Hi,

I need a way to find out whether i have clicked the Cancel button inside the RadProgressArea control. I need to invoke a custom functionality in the
OnClientProgressUpdating() event whenever cancel button is clicked.  I would like to know how this can be achieved. Code Snippets are given.

<telerik:RadProgressArea ID="RadProgressArea1" runat="server" DisplayCancelButton="true" ToolTip="workign" OnClientProgressUpdating="clientProgressUpdating" />                               

 function clientProgressUpdating( progressArea, eventArgs)
  {
             // Identify if cancel button is clicked.
            {
            // Perform my own custom functionality
             }
   }

Thanks,
Divya

Hey Guys,

We're just porting over to IIS7 from 6 and having problems with our postbacks.  Client fires but no server-side response just reloads the page - not even the click handler executes its code. Seems intermittent, but the following error is common:

[NullReferenceException: Object reference not set to an instance of an object.]
   System.Object.GetType() +0
   Telerik.Web.UI.RadCompression.Compress(HttpApplication application) +820
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&amp; completedSynchronously) +171

Now when I remove RadCompression entries from web.config it all springs back to life, with no problems.

So I'm doing something wrong with IIS7.  I have the Registration code in both System.Web\HttpModules and system.webserver\modules.

Any ideas?
thanks

Hi Team,

We are using Telerik 2016 Q1 SP1 Radgrid in our application. And after this latest upgrade, we have noticed this weird behavior of the Client-side data bound Radgrid in our page. When we try to reorder a GridButtonColumn and increase the page size of the grid, the data does not refresh as expected with the correct page size, but remains the same, for instance if the page size was 10 and after reordering, if we set page size to 20, still we see only 10 records, however page size and the records returned from the database are 20. Additionally, this does not happen if we reorder any other column other than GridButtonColumn.

And we already have set the property, even then it does not work.

ClientSettings.ReorderColumnsOnClient = true;
ClientSettings.ColumnsReorderMethod = Reorder

Can someone please let us know fix for this?

Any help is greatly appreciated!

 

Thanks in advance,

Lax

Hello, I have a RadListview where all the items are always in edit mode and I have a button outside the list that should save all the changes made on each of the items, the problem is that when I click on the button all the ddata typed on the controls in the lis view is lost so I always get empty values.

    protected void Button1_Click(object sender, EventArgs e)
    {        
        foreach (RadListViewEditableItem item in rlv_Opportunities.EditItems)
        {
            System.Collections.Hashtable newValues = new System.Collections.Hashtable();
            item.ExtractValues(newValues);
            string id = item.GetDataKeyValue("lequip_id").ToString();

            RadTextBox rtbSO = (RadTextBox)item.FindControl("rtb_SO");

            string strT = rtbSO.Text;        
        }

}

Hi everyone, I am trying to use the Lightweight render mode in UI for ASP.NET AJAX here with Custom Skin generated using the Telerik ThemeBuilder but it just won't work. Maybe I am missing some settings so I attached here the sample project I made (please note that I excluded in the zip file the Telerik dlls since it adds to the size of attachment). I assigned the rendering mode, skin and use of embedded skins under the web.config for ease of changing it since assigning for each controls is hassle. I have already tried using RadFormDecorator using the settings I used in the web.config but found no luck.

I have recently tried updating my website to use the latest version of RadControls

When I loaded a form which had been created using the previous installed version I got the message

"The server tag 'telerik:RadAjaxLoadingPanel' is ambiguous. Please modify the associated registration that is causing ambiguity and pick a new tag prefix."

I therefore decided to uninstall the new version of the controls and added the old dlls to my bin folder instead

I still got the message even though I had uninstalled the controls.

What can I do to get rid of this message?

Dear SIR

I have 2 questions on RadGrid edit template:

1)  When I added a DatetimePicker control, the Time can't be selected from time popup button. it always shows 0:00.  I found it seems not compatible with AjaxToolkit(V15)? is there any solution?

2) I'd like to activate the control change events, e.g. when I change start date time and end date time, I will calculate the time span to display. or I will set control value when an combobox selectedvalue is changed. How do I activate editor's control events?  

 

Thanks very much.
