How do you determine what column fire custom sort event?

What I am looking for in how to determine what column the grid is being sorted on when the CustomSort event is being fired. I see there is a property column that appears to provide this information but it is marked obsolete so therefore will not compile. Could someone point me in the right direction?

Where is IndexFromPoint?

I have a RadListBox on my form. I would like when the user right clicks on the list, the item under the cursor is selected before the context menu is displayed. I know with a standard Listbox, you can use "IndexFromPoint" in the mousedown method.

What is the solution here?

Thanks!

Populating with Data through a Bindinglist

My Problem is that I have to programatically fillup a GridView or Listview which has a Bindlist as datasource.
For now it works, but the GUI object is refreshing and scrolling to the last added row and selecting it.
How can I stay in place for example the first row? Does this work also if the cell is edited?

Overlay/State Icons for nodes

Hi,

Is there a method for adding "State"/"Overlay" icons to tree nodes? Such that you have an Image set for the node, but can then apply an overlay icon to show it's "State"?

This would allow us to show a "Virtual", "Readonly" state on top of the normal HTML, PDF icons we're using etc.

Thanks,
Paul

CreateCell Event

Hi,
I've been following the examples of this thread : http://www.telerik.com/community/forums/winforms/gridview/show-mulitple-images-in-a-gridview-column.aspx

This works fine, if the grid is painted only once. But if i scroll or change rows, the CreateCell event runs.
Also the scrolling make the buttons appear in cells that it should not appear in. I think this have something to do with the reuse of the cells in some way..

In my CreateCell i create an event for the button (like shown in the attached thread). BUt with the CreateCell going crazy all the time, this event is created a lot of times.. how can i avoid this?

Regards
SVein Thomas

Tree From Self-Referencing Data

I'm having problems getting self-referencing data to display in my RadTreeView. I'm using the Q1 2007 release in VS Team Suite SP1 on Vista 32bit.

I'm trying to bind the tree to a DataSet which holds the following Xml data:
<Toc>
<Node>
    <Title>Main Title</Title>
    <Target>d03.xml</Target>
    <id>1</id>
    <parentId>-1</parentId>
</Node>
<Node>
    <Title>Child Title</Title>
    <Target>d0300000.xml</Target>
    <id>2</id>
    <parentId>1</parentId>
</Node>
</Toc>

When using the Property Builder and selecting the DataSet as the DataSource, "Toc" as the DataMember, and Toc.Title as the DisplayMember then I get no items at all shown in the resulting WinForm.

When setting properties in code as below I get the title of the two nodes; however, no graphics or parent/child relationship are shown.

dataSet1 = new DataSet();
dataSet1.ReadXml("d03_toc.xml");
radTreeView1.DataSource = dataSet1;
radTreeView1.DataMember = "Toc";
radTreeView1.DisplayMember = "Toc.Title";
radTreeView1.ValueMember = "Toc.id";
radTreeView1.ParentIDMember = "Toc.parentId";

It's completely unclear in the help file if or how I'm supposed to use the Property Builder to create any nodes when using a bound data source. Is this part of my problem?

I'd certainly appreciate a pointer as to where I've gone wrong.

Requirement of a 3rd Y-Axis

Hi,

My client has a requirement to have a 3rd Y axis, since the Rad Chart tool does not have this feature we planned of having a background chart to display the Y axis based on that we are trying to plot the series on the Foreground Graph.

We have tried to handle this by using Prepaint Event of the chart Control..

The problem we are facing is that The Prepaint of the foreground is executed more than once when my mouse cursor is on the plot area.

Things are fine till this execution is correctly done , But some times the prepaint is executed more than once beacuse of the mouseover.

so ,
1. can some one please give us an overview of the complete Cycle of the Chart ploting
2. explain When and How the prepaint event is triggered and if there is a code where we can stop triggering this event that would also be useful.
Am Using C#.Net 2005.

-- Any Links or any Documents on this can be of great use to us.
-- Prepaint Event is what we are stuck with and This event is fired when i call mouseMove function also...

Thank u in Advance !!
