I need to provide a drag/drop mapping between elements of two lists or even two trees by dragging.
Does telerik provide anything like what is asked in this post: http://forums.asp.net/p/1169599/2157868.aspx#2157868?
 I don't want to drop elements from one tree to another but instead allow the user to "connect" elements of two different trees via a line. I found a similar question in a thread from 2009 that didn't have any satisfactory replies but I was hoping that the answers may have changed in the last 5 years.  Thanks!

I have a rad grid that I bind with 2 data tables.  I need to add a custom row and merge the cells of that row, add a background color and text that spans the row.  Any suggestions on how to accomplish this?

I have a radgrid that is invisible and need to export it to excel.  It works great if I set the visible property to true but I don't want the user to see this grid as it is a combination of 2 grids that the user does see.

I need to update the radWindow control from a button that is located internally in the radwindow.

The scenario I have is as follows:
Since a main form I call radwindow and it displays me another form, which contains a textbox and a radgrid. When I digit something in the textbox and press down on the button to add, I need to reload the radwindow like the effect of having the radwindow.

As I do this?

sorry for my english, is not very good xD!! 

Thank you for your help.

Hi all,

You guys have helped me out tremendously in getting my radwindow working.  I now have another question.  When I am finished with my pop-up radwindow I click a button that closes the pop-up and returns to the parent page.  How can I make the parent page postback and refresh?

Thanks,
Bob

Hello,

 I have a Master RadGrid that has a nested (child) RadGrid inside its NestedViewTemplate.  The nested RadGrid contains multiple GridTemplateColumns.  Inside one of these GridTemplateColumns I have a LinkButton (or it can it a label, it doesn't matter).  I am trying to create a scenario where when the user's mouse rolls over this LinkButton a ToolTip appears that will display information about the specific LinkButton text, and when the user rolls away the tooltip disappears.  The information on the tooltip will be obtained from a database query that will require an ID to be passed to it as a parameter.

I have seen a few examples of using the ToolTipManager and binding it to specific controls in a RadGrid, but none of the examples cover "Nested" RadGrids or how to send parameters.  I've seen an example where it's possible to open a WebUserControl inside a ToolTip, but I have not been able to get it to work.

Is what I want to do even possible or do I have to use something like a RadWindow or JavaScript?  I'd rather use the Telerik controls if possible.  I'd really appreciate any help (such as an example code).

Thanks.

hello,
I am using the trial version of the latest Asp.net AJAX controls.  I'm attempting to get the RadAsyncUpload Custom Handler example working but am stuck with a http 500 "internal error" error.  I cannot get around this error.  I've tried recreating the project from scratch, etc. -- no luck.  My project is, I believe, a duplicate of the example files.  I tried to attach a zip of my project but it is 16 megs (2meg limit).  How can I get a zip of my project to you?  Many thanks -- john

We are encountering an issue with the RADEditor when editing a page in SharePoint. In Edit mode, there is a very small area on the left & right side of the eidtor window wherein when you click on it, the cursor jumps to the bottom of the editor window then goes back up to (or near) the area where the mouse was clicked. This is very inconvenient for users specially when trying to highlight a paragraph since what will happen is the cursor will jump somewhere at the bottom and will highlight that area instead. I've read this forum and found not exactly the same issue (but somewhat similar - i.e. cursor jumps to top of page when mouse hovers outside the editor window or when pressing enter). Does anyone know how to fix this? Any information is greatly appreciated.

I have attached a picture to illustrate what I mean.

NOTE: I added the borders just to emphasize where exactly the jumping occurs (when mouse is click on that area outside of the border).

using a RadTreeList I wonder how to hide the expand / collaps Icon when there are no records under parent item What I found within this platform ishttp://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.htmlbut as far as I can see this does not work for RadTreeList, doesn't it?

Please explain me how to troubleshoot following issue: 
I'm using NeedDataSource event to bind list
protected void RadTreeList2_NeedDataSource(object source, TreeListNeedDataSourceEventArgs e)
{
    DataTable dt = GetDataTable();
    RadTreeList2.DataSource = dt; 
}

In function GetDataTable() two options available:
Option 1 - get data table from execution of database request 
DataTable table = objController.GetMessages();

Option 2: Build table 'manually'
DataTable table = new DataTable();
table.Columns.Add("SubjectId", typeof(string));
table.Columns.Add("Subject", typeof(string));
table.Columns.Add("UserName", typeof(string));
table.Columns.Add("Status", typeof(string));
table.Columns.Add("Message", typeof(string));
table.Columns.Add("Date", typeof(DateTime));
table.Columns.Add("Related", typeof(string));

table.Rows.Add("e6628832-54c7-4b18-ad2e-290065bc56c3", "Subject1D", "Sent", "User1", "Body1", DateTime.Now, "");
table.Rows.Add("e6628832-54c7-4b18-ad2e-290065bc56c3", "Subject1D", "Received", "User1", "Body2", DateTime.Now, "e6628832-54c7-4b18-ad2e-290065bc56c3");

table.Rows.Add("e6628832-54ca-4b18-ad2e-290065bc56c3", "Subject2D", "Sent", "User1", "Body3", DateTime.Now, "");
table.Rows.Add("e6628832-54ca-4b18-ad2e-290065bc56c3", "Subject2D", "Received", "User1", "Body4", DateTime.Now, "e6628832-54ca-4b18-ad2e-290065bc56c3");

Both options return the same table (I compared) and show the same information in the list.
The problem is when I using Option 1, collapse/expand is not working either manually (clicking +) not programmatecally. No errors/exception fired.
This is internal RadTreeList  - not sure how to find reason for such behavior.
