I have the following RadListBox:
     <telerik:RadListBox ID="AttachmentsRadListBox"  CheckBoxes ="true" runat="server" />
it is located in a RadWindow, therefore I am populating it through the following code which is only called when RadWidnow becomes visible:


                AttachmentsRadListBox.DataSource = AttachDT
                AttachmentsRadListBox.DataTextField = "DocumentPath"
                AttachmentsRadListBox.DataValueField = "DocumentID"
                AttachmentsRadListBox.DataBind()
                For Each item As RadListBoxItem In AttachmentsRadListBox.Items
                    item.Checked = True
                Next
So far so good, the RadListBox is populated and all the items are checked.

Now, there is a Save button on the RadWindow when pressed before closing the window I am trying to read the checked items in the AttachmentsRadListBox (Since the user might have changed the status of the checked items). But every effort on reading the items has failed, for example on the Save button click I have the following: 

        Dim test As Integer = AttachmentsRadListBox.Items.Count  // THIS IS ZERO
        For Each item As RadListBoxItem In AttachmentsRadListBox.Items  // THERE ARE NO ITEMS
            If Not item.Checked Then
                Dim DocumentIDToDelete As Integer = item.Value
            End If
        Next
Why is that the last piece of code does not behave as I hope? The AttachmentsRadListBox is not being bounded again through the postback. The only time that it is bounded is when the RadWindow appears. Then the Save button on the RadWindow obviously creates a postback but I don't understand why AttachmentsRadListBox contains no item at that point.

Thank you.​

We recently updated to the newest version 2015.2.729.40 and our Rotator image onclick doesn't work in Chrome and doesn't work on some machines in IE.

 We had <asp:Image controls in our rotator which are rendered as <mg

 To correct this, we had to change the control type to <asp:ImageButton which renders as <input

  Again, this issue only happened after our recent updated to version 2015.2.729.40

 Simplified example below

I am having a strange problem. First let me start by saying that I am using the Telerik controls supplied by DotNetNuke. So I can not "upgrade" to any other version of the Telerik controls. I am stuck with what I am given.

I wrote a module initially using Telerik v2012.2.724.35 (which was bundled with DNN v6.02.09)and it worked great. I unfortunately am forced to upgrade to a new DNN version because of a bog in Telericks RADSchedule (which effect the month of November only). So...now I am running DNN that comes with Telerik v2013.1.403.40

The problem is that when I click on a button inside the RADGrid and the ItemCommand event fires, previously I was able to obtain the value of each cell in the row that the button was activated in. The *same exact code* running in v2013.1.403.40 of Telerick now returns to me "&nbsp;" for every single cell in the row. It's like the new Telerik version doesn't bind the data to the GridDataItem (e.Item) within the ItemCommand event like it used to.

What am I missing? How do I get the selected row's data like I had before?

I have a HTMLChart that I would like to allow a user to right click on a point on the graph and set a start date and then right click on a second point and set the end date.  After the points are set it would then pass the dates into a stored procedure and update the HTMLChart.  How would I go about doing this?  The chart is currently being populated via server-side code.

Hi,

 I have an autocompletebox in my page which uses a wcf service to fetch data. And I have a client template in autocompletebox which has #=Attributes.blabla # fields. WCF service returns the correct structure of data which has Text, Value and Attributes members and Attributes has the values I set. However the client template display these Attribute fields as undefined. I couldn't find any related item in this forum. 

Can you help me? 

Thanks.
