I'm using Oracle Apex Version: 20.1
I have a page item (:P303_ADJUSTAMOUNT) that has a default value that's set via sql query. When the user presses the submit button, I have a DA confirm action that shows a popup window to confirm the amount the user is trying to adjust. This works if the user doesn't change the page item value after initialization, as the modal window displays the value that was retrieved from the sql query (the item's default value).
I created another DA on the page item itself to set the value of the page item on the "Lose Focus" event (Set Value --> PL/SQL). I want the DA to set the item's value to whatever the user has entered at the time. Yet when my confirmation message pops up, the page item is still set to the default value and the value I entered disappears. Where am I going wrong here?
Set Value Dynamic Action
Confirmation Message
Update on 04/26/2022:
I finally got my message to be able to display the page item's value and not the page item's session state value. But I have a feeling I'm doing a little extra work to get the desired result.
New code for dynamic action
Action: Execute JavaScript Code
Code:
var msg;
var amt;
msg = "Are you sure you want to insert a singleton for $"
amt = apex.item( "P303_ADJUSTAMOUNT" ).getValue();
apex.message.confirm(msg.concat(amt,"?"), function( okPressed ) {
if( okPressed ) {
apex.submit('ADJUST');
}
});
Desired Result: Update Confirmation Message
I'm using the date picker to allow a user to select start and end dates.
When the page first loads, both date pickers will display the current month the first time the calendar is opened.
However, I want the start datepicker to open up a view from one year in the past.
I've looked through the api (options and methods) and haven't found anything to specify a month.
Has anybody tried this?
I don't quite get what view means. Just shooting in the dark - if you want to limit the start to 1 year in the past or on certain month in the past, there is a configuration option min.
From the Kendo examples:
<input id="datepicker" />
<script>
$("#datepicker").kendoDatePicker({
min: new Date(2011, 0, 1) // sets min date to Jan 1st, 2011
});
</script>
Update:
var datepicker = $("#datepicker").data("kendoDatePicker");
var d = new Date ();
$("#datepicker").kendoDatePicker({
value: new Date (d.setFullYear(d.getFullYear() - 1))
});
So this should open the "view" at this day 1 year ago. Live at the Dojo
There is a property called dateView that can have the value set.
Dojo Demo
var datepicker = $("#datepicker").data("kendoDatePicker");
datepicker.bind('open', function() {
if (this.value() !== this.dateView.value()) {
this.dateView.value(null);
}
});
datepicker.dateView.value(dt);
This will update the value in the popup calendar without updating the value of the widget itself.
Edit: This actually causes a bug where clicking the selected dateView value doesn't update the actual picker value. I've added a handler for the open event to take care of the mismatch and clear the selected dateView value.
The following issue is that i have 3 calendar controls (different ID) in a ASP.NET page (Framework 4.0), the calendar control is not visible but when i click a button it opens up and lets you select a date, everything is fine until i open the second calendar control when i chose a different date it sets the previous date (from calendar control 1)
Calendedar control code
Protected Sub Calendar1_AddDataControl_SelectionChanged(sender As Object, e As EventArgs) Handles Calendar1_AddDataControl.SelectionChanged
TextBox6_AddDataControl.Text = Calendar1_AddDataControl.SelectedDate.ToShortDateString
Calendar1_AddDataControl.Visible = False
End Sub
Example:
Control 1 Date: 01/14/2013
Control 2 Date: 01/14/2013 but i selected 02/05/2013
Control 3 Date: 01/14/2013 but i seected 02/06/2013
i did my homework trying to read previous questions, looking over the internet and i was unable to find a solution to this, i'm a newbie at coding in ASP.Net using Visual Studio 2010.
I understand your handler methods all have the same body except the TextBox identifier.
When you select a date in your Calendar2_AddDataControl, you want to use its SelectedDate value for the TextBox. The handler method for Calendar2 would look like this:
Protected Sub Calendar2_AddDataControl_SelectionChanged(sender As Object, e As EventArgs) Handles Calendar2_AddDataControl.SelectionChanged
// Display SelectedDate of Calendar_2_
TextBox7_AddDataControl.Text = Calendar2_AddDataControl.SelectedDate.ToShortDateString
Calendar2_AddDataControl.Visible = False
End Sub
assuming it's TextBox7 that should display its selected date.
I am facing problem in Jqgrid. I have a column with hyperlink and on the click of that hyperlink I want row data. Is this possible using Jqgrid. when I am using "getGridParam" I am getting row id as null.
There are two possibilities you can try here:
1) You can use a custom formatter to create the hyperlink, and have a custom attribute on the link where you put in the rowid (prefix the custom attribute name with 'data-' to keep it html5 compatible). Alternatively you could call a javascript function explicitly passing the row id.
2) Instead of the hyperlink's event itself, try using the onCellSelect event of jqGrid where you get the row and column id of the clicked cell, even if its a hyperlink. But this would trigger the event even if the user clicks anywhere inside the cell, not just on the link!.
I'm sure you found the answer to this by now but for some of you using ASP.NET WebForm here is what I used.
Create the Custom Formatter and add it to the column where you want the link to appear:
My columns are from a database I use a Select statement as so:
switch (jqGrdCol.DataField)
{
case "xxx":
CustomFormatter hypLinkxxx = new CustomFormatter();
hypLinkxxx.FormatFunction = "xxxformatOperations"; --> **JavaScript Function**
jqGrdCol.Formatter.Add(hypLinkxxx);
break;
}
Then in the Javascript function:
function xxxformatOperations(cellvalue, options, rowObject) {
return "<a href=somefile.aspx?xxx=" + rowObject[0] >" + cellvalue + "</font></a>"
}
I get the value of the column as a hyperlink.
I had a similar issue and was did look into your question to figure out a solution and I have found out a solution to this.
The solution is by using onCellSelect: function(rowid, index, contents, event)
this gives the rowid and contents ie the content of the cell you have clicked or selected
therfore you can get the entire row of contents which includes your hyperlink as well
Recently i've been working on a rather modest application, which lists contacts. When a detail-link was clicked, a popup would come up with more details and an image of that contact.
The table this was based on contained a column photo_reference, which held a path to a folder under /i/. With this setup, it was easy to get the images working for each contact.
The popup i showed was a bunch of htmlcode i put in the region footer, and hid.
<div id="contact_popup" class="contact_pop">
<div class="contact_pop_imgcontainer">
<img id="id_photo" class="contact_pop" />
</div>
</div>
When the detail was clicked, i retrieved data via an application process, and showed a modal dialog of this container.
Now the scope has changed: users need to be able to upload their own images. So, i went to work and made it so the images get uploaded into wwv_flow_files, and then i move them to a new contact_image table. So far so good. But now i want to display these pictures, and here i'm kind of stuck.
* I could include a column in my IR, and put a blob format mask on it with image. I've got this working, but annoyingly. My image table has as primary key the field 'ID'. My contacts table also has 'ID' as PK.
Since IMAGE:APXT_CONTACTS_IMG:SMALL_PHOTO:ID::::::inline: specifies ID as the PK, it uses ID from my contacts table.
My link between tables is APXT_CONTACTS.CONTACT_IMAGE_ID -> APXT_CONTACTS_IMG.ID.
The way i might make it work is to rename my id field in the image table to contact_image_id. (why couldnt the format mask just take the column it's based on as the value :().
I then could hide the column, and take the image with javascript to show in my popup. However, this preloads all images for the amount of selected rows, which isn't entirely bad, but i'm looking for an alternative first.
get_blob_file_src also seems no use to me because of the limited use of the parameters (file browse item, id field), and even then, could i use this through an ajax callback?
I'd much rather be able to get the image blob via ajax to then display in my popup, but i have no clue as to how to do this. I've made a stored procedure which gets the file to download and call this from an application process (ajax callback), and with firebug i can see the post/response, but i wouldn't know how to get this displayed as an image.
Javascript:
function cimg(){
var get = new htmldb_Get(null, &APP_ID., "APPLICATION_PROCESS=get_img", &APP_PAGE_ID.);
get.addParam('x01', 25);
var greturn = get.get();
alert(greturn);
var pic = new Image();
pic.onload = function(){
document.body.appendChild(pic);
};
pic.src = greturn;
};
Page process:
begin
show_small_photo(apex_application.g_x01);
end;
Stored Procedure:
create or replace procedure "SHOW_SMALL_PHOTO"
(p_contact_image_id IN NUMBER)
is
v_mime apxt_contacts_img.mime_type%type;
v_length NUMBER;
v_filename apxt_contacts_img.filename%type;
v_lob BLOB;
begin
SELECT mime_type, lengthb(small_photo), filename, small_photo
INTO v_mime, v_length, v_filename, v_lob
FROM apxt_contacts_img
WHERE id = p_contact_image_id;
OWA_UTIL.mime_header (NVL (v_mime, 'application/octet'), FALSE);
HTP.p ('Content-length: ' || v_length);
-- needed?
--HTP.p ('Content-Disposition: attachment; filename="'||v_filename||'"');
OWA_UTIL.http_header_close;
wpg_docload.download_file (v_lob);
end;
(I'd rather not have to grant execute to public and call the stored procedure via a link.)
This way i'd only have to load the pictures of links clicked. Though this code doesn't work. I get the alert and see a bunch of those weird chars, so i presume that is the blob talking. But i'm not getting an image anywhere.
Am i missing something? Doing something wrong? I'm totally out of clues.
Instead of my existing code, i might make this work through creating another page, and juggle page items and their values around to try and get the same layout going, and then get that page through ajax?
I'm mainly trying to minimize impact (=work) on the existing app, so i wouldn't have to yet again change pages.
TL;DR: is it possible to retrieve and display an image blob from a table not in the report query, preferably through ajax?
This is Apex 4.02 on an 11g db
Thanks,
Tom
To whom it may concern, here is how i solved/worked around it:
I went with the fetch-another-page route. Maybe i was too technical or too difficult about it in my op, but in hindsight i think i could've boiled it down to:
"retrieve an image blob via ajax and display it".
So if that rings any bells for anyone, let me know.
Some rectifying too:
my images table is a child of the contacts table, as such my FK between those is images.contact_id -> contact.id
I've created a new page in my application, and put a form in based on my images table. I only display 2 items of the type 'display image' (a thumbnail and original size), and 2 hidden items, 'ID' and 'CONTACT_ID'. I've removed all that was not necessary: no buttons, no DML-process, no labels, no templates.
The automated row fetch process takes as 'primary key' my contact id, so i can call the page with contact_id in the url (so that i won't have to do an extra select to retrieve the correct id in the image table).
On the page i need the pictures, i then get the page with the photos on it when required (ie: when the detail icon is clicked and i show my popup).
Following piece of code is called within this function
(only code 'missing' here is where i call another page process to fetch me contact details in a json format)
//page 120 only holds the 2 images for a contact. Due to images being in
//blobs and no easy way to dynamically fetch them, i made a small
//form with the 2 photos on, and id + contact_id
//(contact_id made PK for the ARF-process, since this is what is worked with)
//The page is pulled in, and the photos retrieved
//htmldb_get does not do the job! It only pulls the page from cache, which isnt what i want
// arrays with the arguments and their values for the post
var vArgs = new Array();
var vVals = new Array();
vArgs.push("P120_CONTACT_ID");
vVals.push(cid);
$.post('wwv_flow.show',
{"p_request" : "NULL",
"p_flow_id" : $v('pFlowId'),
"p_flow_step_id" : "120",
"p_instance" : $v('pInstance'),
"p_arg_names" : vArgs,
"p_arg_values" : vVals},
function(data){
var oContainerSmall = $("#id_photo_container").empty(),
oSmallPhoto = $(data).find("#P120_SMALL_PHOTO").attr({"id":"id_photo",
"alt":oContact.lastname + " " + oContact.firstname}),
oLargePhoto = $(data).find("#P120_LARGE_PHOTO").attr("alt",oContact.lastname + " " + oContact.firstname);
$("#large_photo_container").empty().append(oLargePhoto);
$("#large_photo_container").css({"display": "block", "visibility": "hidden"});
//Why remove and remake the container?
//for some reason i couldn't find out, the image width and height get reset to 0 after
// an initial display of the enlarged picture and closing its dialogbox.
//I assume it is an apex+css+javascript issue.
//The only fix i was able to find was to remove the div and remake a new one.
// There have to be some properties set on the div and/or its children through
// the closing of the popup dialog (for the larger picture),
// which then prevents subsequent calls to get the correct values.
$("#large_photo_container").remove();
var oContainerLarge = $("<div></div>").attr("id","large_photo_container").css({"display":"block", "visibility":"hidden"});
oContainerLarge.append(oLargePhoto);
$("body").append(oContainerLarge);
//Hardcoded value here! Adapt when necessary
if($("#id_contact_type").val() == "Conference Room"){
var oLink = $("<a/>").attr("href", "#")
.click(function(event){
explode_headshot(event, this);
});
oContainerSmall.append(oLink.append(oSmallPhoto));
} else {
oContainerSmall.append(oSmallPhoto);
};
$("#contact_popup").dialog({modal: true,
width: 750,
resizable: false,
title: oContact.lastname + " " + oContact.firstname,
close: function(event, ui){
$("#id_photo").attr({"src": "", "alt": ""});
}});
});
I wouldn't call it ideal, but it works, and that's all i need at this time :)
I made a very similar application for showing contact details including photos a few months ago in apex.
I found this web page very useful:
http://blog.hilandco.com/2010/05/how-to-show-blob-type-column-as-image.html
Displaying an image can be as easy as creating an item of type: "display Image". Settings: " Blob column returned by sql statement".
And then an sql statement selecting the correct row:
select blob_content
from my_bitmap_table
where ID = ...
