hi I have a checkbox where I need to check something if it is selected.  In the cellbeginedit event I check the value of the checkbox but it is false when I clearly set it to true. Is there a different way to approach this?  All I need to do is call a function if the checkbox is set to ticked.  The column is also added at run time if that helps. Thanks.

Hi

How to sort pages in RadPageView?

I was looking for method Sort or Comparer property but I did not find anything. Is it possible to sort pages in RadPageView?

I use version 2011.1.11.419.

Regards

HelIo,

I have a structure that looks like following:

Class TreeNode  { 
    public TreeNode Parent { get; } 
    public IEnumerable<TreeNode> Children { get; } 
    public …  
} 

I want to bind this structure to a Telerik RadGrid with detail tables for each level of the children. I know that radgrid supports declarative binding to a self-referencing hierarchy, but that assumes you have a flat dataset (e.g. from a database) and can look at a parent key field of some sort. My question is: It is possible to bound a radgrid to a data structure like the one I mentioned and is there a way to do it declaratively?

Thanks in advance,

Misa

Hi,

When using a CommandBarDropDownButton and having two menu items, the sizing appears to be off (see attached image) and there is a lot of extra padding at the bottom.  This works fine with 3 or more menu items.  Is there a way to correct this?

Thank you.

I have a RadTreeView with top nodes and each top node may have children (subnotes) depending on my database data source.

Top node 1
    |___ Sub node 1
    |___ Sub node 2
    |___ Sub node 3
Top node 2
    |___ Sub node 1
    |___ Sub node 2
    |___ Sub node 3
    |___ Sub node 4
Top node 3
    |___ Sub node 1

I have consigured all my top nodes to have a ContextMenu (radContextMenu1) associated with it.
For all the Sub notes of any top node (so for Sub node 1, 2, 3 of Top node 1; Sub node 1, 2, 3, 4 of Top node 2 and Sub node 1 of Top node 3 and any other subsequent Sub note of any other possible Top node), I want a context menu (radContextMenu2) to appear and I want to do this through C# code, not at design time.
The only example that you seem to provide is how to acomplish this at design time and only with predefined nodes; not database driven ones, like mine.

Here is the only example that you provide:

RadTreeView1.Nodes[0].ContextMenu = radContextMenu2;

This will NOT work in my case since my menu is constantly changing based on my dasaset.
In essence, I am looking for something like this:

RadTreeView1.AllSubNodesAtLevel[0].ContextMenu = radContextMenu2;
(where level 0 would be ALL the Sub nodes in the above pictured schema)

Thank you!

HI,

I have a GridView with a checkbox column. When I would click on the column header checkbox checks all stay true.
Could anyone help me?

Hi,

I have list control with data on a user control.

I have subscribed for a double click event for a listcontrol.

as there are lot of items in the controls, when the user clicking on scroll bar to go donw the list. it is firing the double click event and thus selecting the wrong item, instead of continue scrolling down as the click was on the scroll bar and not on the item.

please advice.

Regards,
khizar

I have tried setting the ThousandsSeparator both in the Property Builder and in code, but it has no effect on the display of the grid's numbers.  I am referencing GridView v2011.1.11.315.

Is this a known issue or am I missing something? 

Hi,

When I move by mistakes a node on the node over him, the application crash with the error bellow.

To reproduce this,
> Create a treeView with 2 nodes inside!
> Move the second node into the first one,
> Do it again (Move the second node that is already into the first one exactly as you did before)

I hope you can reproduce it and tell me how to avoid this problem.

Best regards, Fred

Is it possible to customize Group By labels in the group panel?
I've looked and the following example (http://www.telerik.com/help/winforms/gridview-grouping-formatting-group-header-row.html) and it only demonstrated how to customise group heading rows, not the labels in group panel.
