I am trying to figure out how to change the default layout to 2 columns from 3 columns. I have been able to do it successfully on every page except for search results. I wouldn't mind changing the default layout to 2 columns as I want it all to be uniform.
Here's the catch, I am on a hosted solution (I hate it, but hey, I am just the developer). I have no access to the file system or individual files. I haven't figured out a way to upload and replace any files, so all changes I make have to be done from the back end. I am really hoping this can be done.
Answer is, you can't. Plain and simple.
However, you can hack the hell out of it using jQuery and get it to work right. Here is the code I used:
//Check for 3 col layout.
if($j('.col3-layout').length>0){
//swap the 3 col layout for the 2 col layout
$j('.col3-layout').addClass('col2-left-layout').removeClass('col3-layout');
//grab all the code in the wapper, and place it in the main
var html=$j('.col-wrapper').html();
$j('.main').html(html);
//If products are shown as a grid, reorder them. If it is a list, leave it alone.
if(!$j('.grid').attr('href')){
//Grab all items in the list, push them into an array, and then remove all the data.
var items=new Array();
$j('.products-grid .item').each(function(){
items.push($j(this).html());
});
$j('.products-grid').remove();
//build your output
var html='';
var gridsize=4; //items per row
for(var i=0;i<items.length;i++){
if(i%gridsize==0){//start a new row
html+='<ul class="products-grid '
if(i/gridsize==0)//very first row
html+='first ';
else if(i==items.length-gridsize)//last row
html+='last '
if(i/gridsize%2==0)//even class
html+='even">';
else
html+='odd">';//odd class
html+='<li class="item first">'+items[i]+"</li>";
}else if(i%gridsize==gridsize-1){//very item in row
html+='<li class="item last">'+items[i]+"</li></ul>";
}else
html+='<li class="item">'+items[i]+"</li>";
}
$j('.category-products').html(html); //populate the data.
}
}

So what I'm trying to accomplish is when the grid is fully loaded, I loop over a certain column that contains checkboxes. Depending on the value of the checkbox I should be able to disable it.
Problem is that I can't access the html element that's there. Am i doing something wrong or overlooking something?
What i've tried:
loadComplete: function() {
// Fetch all the ID's of the rows
var rows = $("#table").getDataIDs();
// Loop over the rows
if(rows.length != 0){
for(i=0; i < rows.length; i++) {
// Get the data so we test on a certain condition
var row = $("#table").jqGrid("getRowData", rows[i]);
if (row.gridCheckbox == 1) {
//disable the element
row.prop("disabled", "disabled");
}
}
}
}
It's important to understand that changing one element on the page follow in the most cases to web browser reflow: validation whether some property (position for example) need be changed in all other elements on the page. If you do changes in the loop then your JavaScript code can be really slow.
Thus it's strictly recommended to reduce the number of changes of the DOM. Especially to reduce the number of changes jqGrid provides rowattr, cellattr and custom formatters. If you need for example to set disabled attribute on some rows then you should now do this in loadComplete, but to use rowattr instead to inform jqGrid that some additional attributes (disabled="disabled") should be set on some rows. jqGrid collect first the string representation of the whole table body and it use one assignment of innerHTML to fill the whole body of the grid in one DOM operation. It improves essentially the performance. See code example in the old answer.
I have 6 textboxes at the top of the screen that update an entire column(one textbox per column) based on any changes. I was selecting the columns based on their class (.l#). Here is the code (issues to follow):
function UpdateField() {
var ctrl = this;
var id = parseInt(ctrl.id.replace("item", ""), 10) - 1;
var bound = [".l1", ".l7", ".l8", ".l9"];
var fields = $(bound[id]);
for (var i = 0; i < fields.length; i++)
{
fields[i].innerHTML = $(ctrl).val();
}
};
which is bound to the keyup event for the text areas. Issues are:
1) initially fields.length was -1 as I didn't want to put data in the "add new
row" section at the bottom. However, when running it, I noticed the
final "real" record wasn't being populated. Also, when stepping through, I
noticed that the "new row" field was before the "last row" field.
2) when doing it this way, it is purely superficial: if I double click the field,
the real data hasn't been changed.
so in the grand scheme of things, I know that I was doing it wrong. I'm assuming it involves updating the data and then forcing a render, but I'm not certain.
Figured out how to do it. Modified the original code this way:
function UpdateField() {
var ctrl = this;
var id = parseInt(ctrl.id.replace("item", ""), 10) - 1;
var bound = ['title1', 'title2', 'title3', 'title4'];
var field = bound[id];
for (var i = 0; i < dataView.getLength(); i++)
{
var item = dataView.getItem(i);
item[field] = $(ctrl).val();
dataView.updateItem(i, item);
}
grid.invalidate();
};
I have 6 textboxes (item1-item6) that "bind" to fields in the sense that if I change data in a textbox, it updates all of the rows and any new rows added also have this data.
Parts where the two issues can be explained this way:
1) to work around that, though still it would be a presentational fix and not a real updating of the underlying data, one could force it to ignore if it had the active class attached. Extra work, and not in the "real" direction one is going for (masking the field).
2) It was pretty obvious with the original implementation (though it was all I could figure out via Chrome Dev Tools that I could modify at the time) that it was merely updating a div's content and not actually interacting with the data underneath. Would look nice, and perhaps one could just pull data from the item1-item6 boxes in place of the column if it is submitted, but if someone attempts to modify the cell, they'll be looking at the real data again.
I need to select a specific row in kendoGrid but NOT by data-uid (as data-uid is changed when the grid dataSource is loaded again) but by the row itemID. I saw posts but they only select the row by uid which is not what I needed, I actually need to restart the HTML5 application and when grid is loaded, a specific item should be selected. This is what I've been seeing
Demo: jsfiddle.net/rusev/qvKRk/3/
e.g. the object has OrderID as ID, and every time the grid is loaded, it will be the same, unlike uid, I want to know how will I be able to select a row with OrderID, instead of uid.
You cam mix row itemID and data.uid, I guess.
var grid = $("#Grid").data("kendoGrid");
var dataItem = $("#Grid").data("kendoGrid").dataSource.get(itemID);
var row = $("#Grid").data("kendoGrid").tbody.find("tr[data-uid='" + dataItem.uid + "']");
Going along with what umais has mentioned, the better approach, since there is no built in functionality for this as of yet, would be to iterate through all the records to find the one you need. The function that I built will work even if there are pages of data. The only other way that I can think of doing this would be do do a secondary ajax call; But this works well. Note that i haven't tested it with more than 2000 records.
var dataGrid = $("#GATIPS").data("kendoGrid").dataSource;
var numOfRows = dataGrid.total();
var currentPageSize = dataGrid.pageSize();
dataGrid.pageSize(numOfRows);
var dataGridData = dataGrid.data();
for (var i = 0; i < numOfRows; i++) {
if (dataGridData[i].uid == e)
return dataGridData[i];
}
dataGrid.pageSize(currentPageSize); // reset the view
e is the UID. However this can be substituted for what ever variable you need just replace the check.
a work around that I managed to have, was to go through all rows and check which row model has that ID equal to the parameter, and then get that row data-uid and select the item through data-uid. It's working fine for me, since there were no suggestion, it's the better answer for now.
Well, accordingly to what I have done (and worked for me), and even though the work around isn't the prettiest, set one more Column, with your model id and with ClientTemplate then create any html object (div in my case) inside it give it a html id of your id, so when ever you need it, you just have to go and look with something like:
grid.dataItem($("td div#id").closest("tr"));
Because remember that the dataItem method is waiting for a selector then you get your selectedItem as regular one.
EDIT:
I forgot to say, that you should (or could) use the style property
display:none
If you don't want to display that col.
I have a problem with my product view. I want to display product data. each product is a "box" with an image and text. I want to display six products on a panel. As of the fact that i have many products i want to have a "carousel like view". My idea was the following: Place 6 products on a panel. Load 3 panels and place each panel as a carousel item so that i can swipe to get to another "page".
To save performance I tried to always have only 3 items in the carousel. The active "page" and the page before, and the page after, so that I can swipe to left/right and the next page can be loaded.
I tried to put my logic in the "onActiveItemChange"-Listener of the carousel, but I had massive problems with adding/removing carousel items. So my Question is is it possible to do what i want to accomplish?
Is there a better alternative? Of course my data is in a store, but I don't want that standard list view.
Another Question: Because my first attempt with the carousel failed i tried to build a Ext.Container (card layout) with the panels on it. But how can I listen to a swipe event on a Panel???
thanks for help ;-)
Even I am doing the same, using carousel & a store. Every page of carousel is a view(panel) which would have 4/6 child views(panels). On store load I am creating those children and then divide them into pages and add those pages to carousel.
This is working fine for me and on activeItemChange I am loading more pages:
activeitemchange: function(container, value, oldValue, eOpts) {
var activeItemIndex = container.getActiveIndex();
var galleryTotal = container.getInnerItems() ? container.getInnerItems().length : 0;
if ((activeItemIndex + 1 == galleryTotal)) {
console.log("At last page, time to load");
var store = this.config.store;
store.nextPage({ addRecords: true });
}
}
I think I understand your issue. Assuming you've got 3 items and you're always viewing the middle one (as you move forward, item 0 gets destroyed and one item gets created). And assuming that each item has an id associated with its location in the list.
var current_item = Ext.getCmp('carousel_name').getActiveItem().getId();
current_item = Number(current_item.replace('item', ''));
//Objects to create
var next_item = current_item + 1;
var previous_item = current_item - 1;
//Objects to destroy
var next2_item = current_item + 2;
var previous2_item = current_item - 2;
//Create items
var createItem = function(item_location, type){
var carousel_item = create_content(item_location);
if(type == 'next'){
Ext.getCmp('carousel_name').add(carousel_item);
}else if(type == 'previous'){
Ext.getCmp('carousel_name').insert(0, carousel_item);
Ext.getCmp('carousel_name').setActiveItem(1);
}
}
createItem(next_item,'next');
createItem(previous_item,'previous');
//Destroy items
if(Ext.getCmp('item'+previous2_item)){
Ext.getCmp('carousel_name').getItems().items[0].destroy();//This is a hack, for some reason with the above commented out line, the item was getting destroyed but wasn't being removed from carousel_name
}
if(Ext.getCmp('item'+next2_item)){
Ext.getCmp('carousel_name').getItems().items[Ext.getCmp('carousel_name').getMaxItemIndex()].destroy();//This is a hack, consistency with previous destroy (above)
}
Ok, let me explain my scenario more clearly:
When a cell is edited, it becomes 'dirty' and I style it a certain way by adding a CSS class to the cell via javascript.
Then, if the user Sorts the grid, the styling is lost (I believe because all the rows are recreated) and I need a way to restore the styling to the appropriate cell/row after a Sort.
What I attempted to do is add an entry into data[] called 'status' and onCellChange I loop through data[] and match the args.item.Id to appropriate entry in data[].
grid.onCellChange.subscribe(function (e, args) {
var done = false;
for (var i = 0; i < data.length && !done; i++) {
if (data[i].id == args.item.id) {
data[i].status = "dirty";
done = true;
}
}
}
However, onSort I'm not sure how to match the sorted rows to the data array. (Since I have no args.item) I've attempted to do selector statements:
$(".slick-row")
to restyle the correct cells, but I have no way to associate the rows with their entry in data[].
1) There is no need to search for the item in your onCellChange handler - it is available at "args.item".
2) Sorting the "data" array will not wipe out your change to the item in #1.
3) You mention dynamically styling cells. I see no code for that. If your custom formatter is the piece of code that looks at "item.status" and renders it differently if it is dirty, then you don't have to do anything extra. Sorting the data and telling the grid to re-render will preserve the "dirty" cell styles.
