I have a RadGrid with a hierarchy view (about 5 levels deep).  I bind programmatically in the OnPreRender event.  EnableViewState=false.  The ItemCommand event fires for any item in the first three levels of the hierarchy but when I try to expand something beyond that level, the event doesn't fire anymore.  Any ideas?

Hello,

I need to build same code as in this sample but I have no declarative datasources.
Is there somewhere some samples off a full code behind version.

How to have the master grid triggering an ajax event to rebind details when a row is changed, how to select first row and, if exists, first details row.


Thanks for help.

I've created a system for importing images, where each image is "processed" during the import process.  This process allows you to resize, crop, flip, rotate, add whitespace, etc.  For the whitespace, I allow the user to select a color (so that the whitespace can be blue, for example).  To do this, I use a RadColorPicker.  (My first time using this control!)

My problem occurs when I import a lot of images.  (I'm using the multi-file upload control - thank you!)  For each uploaded image, I show a processing panel that allows them to manipulate the image.  If there are a lot of images, there are a lot of panels.  Each panel is probably about 400-500 px high, which can make for a long page.  When it's over 9999 px high, you start seeing these hidden sliders.  In the HTML source, I see the following:


If you look, you can see there is a slider (class="RadSlider RadSlider_Default" style="position:absolute; top:-9999px ...)

Is there a way to get rid of this?  Obviously, you're hiding this.  Can't you do a style="display:none;" instead of shoving it up so high?

I've uploaded a screen snapshot to show this.  Note the slider stuck in the middle.  This is actually related to another color picker that is in a similar window/tile farther down the page - like 9999px farther down.

Thank you.

How can I prevent a user from uploading two files with the same filename using the asyncupload control?

How can i validate the *.mp4 format only in RadUpload?

I tried like AllowedFileExtenstion=".mp4";  But it doesnt work for me.

I am relatively knew to the Telerik controls but have been a developer for several years. I want to implement a load on demand combo box for my newest project(well several really), the control will load from a page method. I got the control to load initially, but as you type the dropdown just bounces a little without narrowing the search or showing any type of error. Below is the code that is currently being used for the control, and page method.

private const int ItemsPerRequest = 20;

[WebMethod]
public static RadComboBoxData GetContributors(RadComboBoxContext context)
{ 
     DataTable data = GetContributors(); 
     RadComboBoxData comboData = new RadComboBoxData();
     int itemOffset = context.NumberOfItems;
     int endOffSet = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count);
     comboData.EndOfItems = endOffSet == data.Rows.Count;

     List<RadComboBoxItemData> results = new List<RadComboBoxItemData>(endOffSet - itemOffset);
     for (int i = itemOffset; i < endOffSet; i++)
     {
          RadComboBoxItemData itemData = new RadComboBoxItemData();
          itemData.Text = data.Rows[i]["Contributor"].ToString();
          itemData.Value = data.Rows[i]["ContributorID"].ToString();
          results.Add(itemData); 
     }

     comboData.Message = GetStatusMessage(endOffSet, data.Rows.Count);
     comboData.Items = results.ToArray();
     return comboData;

}

private static string GetStatusMessage(int offSet, int total)
{ 
     if (total <= 0)
     {
         return "No matches";
     } 
     else
     { 
         return string.Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", offSet, total);
     }
}

I have a page with several editors and I would like to have a single toolbar to use with all the editors. This toolbar should always be visible.

I have created a sample page that is CLOSE to what I want. However, the toolbars are being duplicated - one for each RadEditor. I know that I will have to use to javascript change which Editor is active when the toolbar is clicked. That's no problem, though.

What do I need to change to only have 1 toolbar that's always visible?

I am using the following RadContextMenu in conjunction with a radgrid


As you can see I am using a web service call to populate the menu items of a submenu when I right click on one of the grid rows. This works perfectly.

However, I have run into a problem. The service call at times can take a second or two. That is not really an issue. However, if I select to expand the menu item that is populated using the web service (thus initializing the web call), then click a different menu item (which performs a partial postback) before the web service populates the menu, I get the following error:  'this.get_element()' is null or not an object.

I am guessing that the callback function for the webservice is looking for the radmenu and not finding it, because a postback has occurred. Using the OnClientItemPopulationFailed to suppress the error does not work. I would like to cancel the service call in the OnClientItemClosing event. Does anyone have any idea how to get an instance of the web call and abort it?

Thanks
