I'm going to try and make this as short as possible another developer created some controls, I am attempting to use a checkboxlist that when an item is selected to have the data entered in a Listbox.  With using a postback the page refreshes every time I select an item, so I started searching on how to postback without refreshing the page. The closest that I have gotten is with the attached code; the issue with the current code is the information is entered into the box but it is as though some event is waiting to happen after I select an item because I am getting the spinning symbol when I move around various spots on the page and it prevents me from clicking on a seperate button while this is occurring.  If anyone can provide any assistance please help.  I have attempted to use the below forums as reference.

We are using the RadGrid control to retrieve User objects from a repository that uses NHibernate to retrieve the objects. I am using an object data source defined as:

The method signature for GetAll is as follows:

With NHibernate, some Users are actually AdminUsers which extends User. It seems the repository is currently returning an AdminUser object first, and the control seems to be assuming then that the rest of the objects will be AdminUser rather than User. This causes the following exception to be thrown:

Is there a way to force the control to assume that data bound objects are User rather than AdminUser? Thanks!

Working Code: I have a Grid, and it has list of filename's with radio button. If I select a radio button, I can display image for the filename in the RadImageEditor. If I change the radio button or click another row, the image is updated properly. When image is displayed and If I click on zoom in zoom out, and then reset, the image is displayed in its original form the way it was loaded.
1) The problem comes when I first rotate an image, then click on reset changes , the image does not come to its original form the way it was initially loaded.
2) Continuing the step 1, if I now try to change radiobutton so try to load another image, an error is thrown.

Let me know any better way or possible solution to this issue. The demo does not give proper information for this issue, so putting in this forum.

I'm trying to Clear a RadComboBox in javascript, and have it post back (when AutoPostBack is enabled). I've been searching around for a solution, and this is the best I can come up with - but it feels incredibly hacky - is there a more appropriate method of doing this?


Thanks

Hi Telerik developers;

This problem RadGrid in radwindow open in server side GridClientSelectColumn selected

Gird in Columns


C# is Radgrid item data bound

RadWindow open and grid columns no selected GridClientSelectColumn
I want you selected the selected object
This radwindow image in click

I have a RadGrid that displays the results of a query submitted by the user. If the user requeries I want the vertical scroll position to be at the top of the grid, not at the position of the previous query. How do I do this?

I have tried the following in the PreRender event all to no avail:

           RadGrid1.MasterTableView.CurrentPageIndex = 0;
and this..

          if (RadGrid1.MasterTableView.Items.Count > 0)
            {
                RadGrid1.MasterTableView.Items[0].Selected = true;
            }
Here are my property settings

        <telerik:RadGrid ID="RadGrid1" runat="server" AllowSorting="True" Width="100%"  
            Height="450px" ShowStatusBar="True"
            AutoGenerateColumns="False" CellSpacing="0" GridLines="None" 
            onprerender="RadGrid1_PreRender" 
            onitemdatabound="RadGrid1_ItemDataBound" 
            ondetailtabledatabind="RadGrid1_DetailTableDataBind" 
            onneeddatasource="RadGrid1_NeedDataSource" 
                OnItemCreated="RadGrid1_ItemCreated"

Hi - After upgrading from Q3 2013 to Q3 2013 SP1 I get borders around my check boxes in IE 8.  Chrome and firefox do not have them. 
You can see this here in your demo
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

Is this change expected behavior for IE 8? or is this a bug?

Thanks

Hey

I'm trying to figure out how to edit the default css in the webresource.axd file, as its failing compatibility and accessibility tests. 

For example..

*html .RadTreeView .rtMinus{margin-right:1px}

Anyone know where I can find that file and edit it?

Thanks

John

Hello,
    In the web application we are developing using the latest version of RadControls for Ajax, we make use of RadSplitter and RadTabStrip. We would like to format the selected tab's  text as bold so we have tried several approaches to accomplish it, one of them using the tab's SelectedCssClass:
The other approach we have tried is to directly modify the CSS class of the selected tab:

Both of these approaches produce the expected result but are also causing a problem: the last tab in the tabstrip ocassionally disappears. We have looked into the issue using Firebug and we noticed that the inner list of the tabstrip does not update its width when a tab caption is made bold (therefore the tab width increases) and it causes the last tab to be wrapped on the following row because there is not enough room left for it.
We have tried updating the list's width through client side code every time a tab is selected, but we couldn't get the tabstrip to work properly given that it also has the scroll buttons enabled.
Please advise us on how to fix this issue.
Thank you.
