Hi,
I have problems retrieving the text of a raddropdownlist.
I populate the ddl in a quite basic way (Articles is a datatable):

Changing the selected value triggers nothing.
A button near the ddl triggers some events (basically, a databind on a radgrid); at this time i need to read datatextfield and datavaluefield:

ddlArticle.SelectedValue works perfectly and opv really contains the selected value, but ddlArticle.SelectedItem.Text throws an exception:

Exception thrown: 'System.NullReferenceException' in App_Web_prodotto.aspx.11948b1e.cmqcknjt.dll ("Object reference not set to an instance of an object.")

So i tried another way:

Again, opv contains the correct value, but Item.text is null, and Item is null too.

I am using Telerik 2016.3.

Thank you for any help you can provide.

HI,

I  am using a Batch Mode to do updates and deletes,I am using GridButtonColumn for delete  operations and I am using OnDeleteCommand to bind the server side code. Now when I click the Delete buttons the row is deleted on Client side but server side even is triggered only when I hit 'Save Changes' which is fine.

I want to disable the row until the user hits save changes button(for visual indication that this row is marked for deletion and will be deleted on hitting save changes button) and causes a post back.

Thanks,

Harish.

There are 4 directories I'm curious if I need to distribute along with our deployed web products:

RadControls

Scripts

TabControl

radSkins

There are some compatibility issues which we are facing corresponding to the Radtreeview in IE 11 browser. We are getting a JavaScript error on a particular function which is called on the "OnClientNodeClicking", due to which the page is not rendering in the IE 11 browser. However, the same page is rendering fine without any JavaScript error on IE 8.

Please provide a solution for this

I'm having difficulty finding a way to accomplish what I want to do.

My Webform has the following controls on it:

1.  RadTextBox

2.  RadButton

3.  RadGrid

Very simple.   The user is prompted (RadTextBox) to enter the first letters of the customer name that they would like to view (RadGrid).  When they click on the view button (RadButton), the code behind executes in button click event to query the data and executes a .Rebind to refresh the RadGrid.  That all works very well.  My problem is that I'm trying to find a way to empty the RadGrid datasource when the user clicks back into the RadTextBox and it receives focus.  I found a few lines of Javascript in another post on the Telerik forms.   

Here is the script:

            var masterTable = $find("<%= RadGrid_CustData.ClientID %>").get_masterTableView();
            masterTable.set_dataSource([]);
            masterTable.dataBind();

I am able to execute this javascript code from a client-side button click event, but it fails when I try to execute it from the RadTextBox OnFocus client event.   

Does anyone have any ideas on how I can accomplish this ?

Thank you

Hi,

I'm trying to create a multi-column dropdown list based on this example: Telerik APS.Net ComboBox Demo. My problem is I'm getting my data back as a DataSet, it's not a DataSource, and I'm unclear as to how to bind the dataset to the control. I tried using the evals etc as described in the example, but I get an error DataSource expected.

Any help would be greatly appreciated.
