I was working on Dhtmlx grid . I used the Clist ( Multi-select-combo-box ) data-type . Once the selection is made , I need to validate the list of the selected items . Can some-one who is familiar can help suggesting how to attach event for the "onChange" for Clist datatype ?
Unfortunately, such feature is not available.
All changes can be validated only after the closing the CList select box closing.

I'm not sure how it is possible to get the same contextmenu for an unbound form's control like for bound controls, both with a date value.
There are two unbound controls which get their control value via:
txtErsteSpende:
=Wenn([spSurrKey]>0;DomMin("[zaZahlDatum]";"[tblZahlungen]";"[zaSP_FKEY] = " & [Formulare]![frm110_Spender]![spSurrKey]);Null)
and
txtLetzteSpende:
=Wenn([spSurrKey]>0;DomMax("[zaZahlDatum]";"[tblZahlungen]";"[zaSP_FKEY] = " & [Formulare]![frm110_Spender]![spSurrKey]);Null)
Sorry for these are examples in german: "wenn" means "iif". It seems the bound control allows the context menu but not available for unbound controls.
Or is there a technique without writing vba-code to allow same context menu for both kind of controls?
Any suggestions appreciated
thx
Contextmenu filter a date - bound control
Contextmenu filter a date - unbound control
the goal was:
make the form updatable
display the date contextmenu for the two textboxes
After trying around with subforms which wasn't practable because the form is displayed in data sheet view I found this solution:
qry110:
SELECT tblSpender.spID, tblSpender.spNachname, tblSpender.spVorname, tblSpender.spOrt, tblSpender.spGebdat, DMin("[zaZahlungsdatum]","[tblZahlungen]","[zaSPFKEY] = " & Nz([tblSpender].[spID],0)) AS datErsteSpende, DMax("[zaZahlungsdatum]","[tblZahlungen]","[zaSPFKEY] = " & Nz([tblSpender].[spID],0)) AS datLetzteSpende
FROM tblSpender;
=> works fine but shows #Error in the form's textbox when in table tblZahlungen there is no entry (no ForeignKey) for the PrimaryKey in tblSpender
So I created a second query as recordsource for frm110 based on the first qry110 which checks the NULLvalue:
qry111:
SELECT qry110_Spender.spID, qry110_Spender.spNachname, qry110_Spender.spVorname, qry110_Spender.spOrt, qry110_Spender.spGebdat, IIf(Nz([datErsteSpende],0)>0,DateValue([datErsteSpende]),Null) AS datumErsteSpende, IIf(Nz([datLetzteSpende],0)>0,DateValue([datLetzteSpende]),Null) AS datumLetzteSpende
FROM qry110_Spender;
It works and now the form's recordset IS updatable.
Maybe the form isn't very performant for big data but it's acceptable for my users
thx for your hints
contextmenu for date textboxes
there is a feature called "Filter Row" in Kendo Grid
http://demos.telerik.com/kendo-ui/grid/filter-row
I want to add a drop-down list instead of a text box or a number box, to the filter box. It's for filtering a column that has countries. So I want list of countries in a drop-down list. How can I do this?
It's very similar to the custom Filter Menu (http://demos.telerik.com/kendo-ui/grid/filter-menu-customization). I made the mistake of no using valuePrimitive: true. You might not want it in your situation but keep that in mind.
Here's a sample: http://dojo.telerik.com/OKaS
Also, the filter menu should take up the editor model of the column but it's not always what you want.
Edit
Starting from 2014 Q2 SP1, the template function now receives an object containing "datasource" and "element". In my example, you would have to change the dropdown initialization from "container.kendoDropDownList" to "container.element.kendoDropDownList". The datasource is empty in my example but I'm assuming this can be used to pass the choices to a control without requiring another datasource or to externalize your current. I have not experimented with this feature but I suggest you do before taking my sample blindly.
As Pluc mentioned earlier valuePrimitive: true will help you create a custom filter for your grid/columns to send id's to your controller, if you are not using setting this property true you will receive an Object in your controller instead of a number, the conversion will not be made automatically . This is still working as of 2019
I just found that sample
http://www.ok-soft-gmbh.com/jqGrid/DataToMultiSelect2.htm
I want to have something similar:
I want to be able to post selected values on server and also i want to have a dropdown and based on that dropdown selection another cell value of that row gettign changed
How can i do that?
|Id|Dropdown|ValueChangedOnDropdownChanged|
1 A[A/B] A selected
2 B[A/B] B selected
*[A/B] it is dropdown options
I am not sure that I understand your question correct. The demo which you reference in your question I created before for the answer and this one.
Look at the another old demo. It shows how to implement dependent select (dropdown) list. The demo shows how to it in inline editing, form editing and the searching toolbar. In case of the usage of server base data you will have to use dataUrl and buildSelect to implementation of the same behavior. The dataUrl should be used instead of the v property of the searchoptions or editoptions. The buildSelect can be used ton only to modify the server response, but just as the good place to rebuild the dependent select (dropdown list).
I have a gridview with one column of checkboxes and other columns with different custom controls .
What I want is that when a checkbox is checked an event is triggered which toggles the visibility of other elements in the row .
You can use the approach, illustrated in the http://www.devexpress.com/example=E2284 Code Central example as a starting point to accomplish this task.
Hello sir I am new to the jsp and ajax world. my problem is
If i select one combo option then it should change the other combo options dynamically without submit button press.
for example if i select the country then it should shows their states in other combo.
I am using servlet & JSP and MS-ACCESS as backend. please reply as soon as possible.
THANKING YOU....
You need:
A piece of JSP which returns a string which can be parsed in javascript to create a list of possible combobox items (value, name) to select in the SECOND combobox, based on a VALUE which can be selected in the FIRST combobox
A piece of javascript which receives the onChange event of the FIRST combobox and uses the then selected value to create a XMLHTTP-request to your JSP (at 1)
A piece of javascript which you can pass to the XMLHTTP-request onReadyStateChange event to execute, which reads/parses the parseable string (from 1) and fills the second COMBOBOX with those values
Good luck
