Attribute value is not persisting

[Anirban]

I am using RadCombobox in a grid. I have assigned attribute to the rad combobox from Javascript method. The code is below

 var masterTable = $find("<%=radgrdChargeType.ClientID%>").get_masterTableView();
         
         var dataRow = masterTable.get_dataItems()[popupTextControlId];
          var radCmbBxChargeType = dataRow.findControl("radCmbBxChargeType");
 radCmbBxChargeType.trackChanges();
          radCmbBxChargeType.get_attributes().setAttribute("Ani", "Vai");
          radCmbBxChargeType.get_attributes().setAttribute("1", "2");
          radCmbBxChargeType.commitChanges();


Now I am trying to get the attribute value from Code behind page.

 RadComboBox radCmbBxChargeType = gridItem.FindControl("radCmbBxChargeType") as RadComboBox;
            if (radCmbBxChargeType.Attributes["Ani"] != null)
            {
                string att = radCmbBxChargeType.Attributes["Ani"];
            }


But here the data is not persisting, i.e. 
radCmbBxChargeType.Attributes["Ani"]  is showing null.


How I can get the value !!
Note. - getting the exact combobox is not a problem.

It's urgent

Hi Anirban,

In general the custom attributes are supported by the RadComboBox's items not by the control itself. This is why a custom attributes assigned to the RadComboBox are not persisted upon post-back.
Please refer to the following help article discussing this functionality.

Hi Terziev,

Thanks a lot for giving me the reply.
But in case of Radcombobox we have Attributes which we can use at code behind page.

Ex. -

RadComboBox 

radCmbBxMeterDataType = 
        e.Item.FindControl("radCmbBxMeterDataType") as RadComboBox;

string name = 
        radCmbBxMeterDataType.Attributes["

FirstName"];

We can go in that way.Am I right !
But if we assign the attribute to the combobox from javascript and try to access that from Code behind page, it
is giving me the error.

Hi Anirban,

Please, use trackChanges() and commitChanges() as shown in this help topic -
