I have a situation where I drag from a RadListBox to a RadTreeView.  It is quite similar to this Telerik example.

When a RadListBoxItem is dropped, it fires the OnClientDropping event.  The event argument has a get_sourceItem() method where I can access the RadListBoxItem and its attributes.  The event argument also has a get_destinationItem() method, but it is coming up null.  I'm guessing this is because the destination item is a RadTreeNode and not a RadListBoxItem.

I need to compare a custom attribute in the source and destination items before I allow the drop to occur.  How can I get a reference to the destination RadTreeNode and check its custom attributes inside the OnClientDropping event handler?

Thanks!

In IE8 the filter boxes are not aligned with the columns. I converted IE8 to compatibility mode and everything worked fine. I am wondering if there is a work around or did telerik provide a solution to this problem. If anyone has a quick fix it would be appreciated!

Hi Telerik,

I am using a RadGrid with a NestedViewTemplate. Within that NestedViewTemplate is another RadGrid.
All data is binding correctly using Advanced DataBinding techniques. My problem is the nested grid just will not fire the "ItemCommand" event.

If I say add a button within the template this will fire correctly. It's just any commands sent from the inner grid that wont fire.

I've tried adding an ItemCommand eventhandler directly to the inner grid but still nothing. So in the code below the "AddPayment" command fires as it's a button seperate from the grid. But no matter what I've tried (GridButtonCol, Button within a Template Col etc)
no ItemCommand is fired for RadGrid: Payments.

I am trying to uncheck all nodes in a treeview using the clientside API.  I noticed that in the documentation, there is an unselectAllNodes() method, is there a way to do this to uncheck nodes too?

Edit:

This did what I needed: 

It is strange, I followed the example online and it is not functioning as expected. I have three textboxes when GRid is in edit mode and two of them are supposed to be currency and the other just plain text. But the RadInputManager is forcing the Plain textbox to be currency as well. This even after the datatype was set to string. Help please

hi there i would like to override couple of sitemap css like lets say
RadSiteMap .rsmItem {  

Hi,
  I realize this may be an odd question, but here is my situation, i have two tables:
table1:
stateid, statename

table2:
CountyId, CountyName, stateId

I'm trying to have a structure like this:

Statename
 --> CountyName

my challenge is how to relate the two table to get the parentId. 

I think the answer is simple but for some reason I just can't get the sql right.

Cal

For this code:

http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/outlookstyle/defaultcs.aspx

Is it possible to remove the field name : from the group header text (so the grouping only shows the value, i.e. "Saturday,March 28, 2010").

Thanks,

Richard

I am using RADGRID for listing related things and grid is loaded dynamically.

I have issue with filter control of RADGrid. It works fine for the first time and after pagin/sorting it stops working and giving this error
"'null' is null or not an object". While debugging I found that this is some viewstate related issue but I am not able to solve it.

Pls suggest on this.

Regards,
M G
