I'm trying to rebind same grid to different datatables. The problem occurs when after sort by column gridview is rebound. During rebind it crashes bypassing catch..

Has anyone come across this (run this method , sort the gridview on any columns and run method again)

try

{

dt = new DataTable();

dt.Columns.Add(new DataColumn(string.Format("{0}{1}", "x", (new Random()).Next(1, 20))));

dt.Columns.Add(new DataColumn(string.Format("{0}{1}", "y", (new Random()).Next(43, 320))));

for (int i = 0; i < 15; i++)

{

DataRow dr = dt.NewRow();

dr[0] = (new Random()).Next(1, 90);

Thread.Sleep(100);

dr[1] = System.Convert.ToDouble("1." + (new Random()).Next(1, 203222));

dt.Rows.Add(dr);

}

dt.AcceptChanges();

this.dataGrid1.DataContext = dt;

this.dataGrid1.Rebind();

}

catch (Exception e)

{

string x = e.Message;

return;

}

Drag&drop (some restrictions) .. Treeview

Hi.

I am using the TreeView control.
however, there are some restrictions I need enforced.
Basically I want the user to be able to re-arrange the sub items in a tree node but not be able to drop a node outside of its parent.
How can I do this?

Lower part saw the same contents question.
Will be a plan which will upgrade. Now is the use possible?

Reply will wait.
Thanks...

Scrolling with Long Tree

Hello,

I have a long tree view, where the tree items go below the viewable area of the page. I tried wrapping this with a ScrollViewer, but that didnt' do anything. How can I enable scrolling for this long tree?

Right now, the list of items is truncated.

Thanks.

Encapsulating the grid

I'm interested in encapsulating and extending the RadGridView, for example adding New Row and Delete Row buttons above the grid, as a UserControl, but still support XAML manipulation of the GridView by the window upon which my UserControl exists.

Is there a way to add the buttons, etc. with Templates? (instead of encapsulating in a UserControl)

Thanks!

[Solved] GridViewComboBoxColumn values are hidden when using ComboBox DataTemplate

Hello,
I'm using dotnet 3.5, WPF.
XP pro SP3.
IE6.0.2900
RadControls_for_WPF_2009_1_0526_TRIAL
C#

I have created a simple RadGridView with a GridViewComboBoxColumn column.
I have added a combobox "DataTemplate" so that the column cells will look like a combo, and not just
when pressing on one of the cells.

In the constructor of the window1, I call FillStatusComboColumn() to fill the combo with possible values.

*** The problem is that using the "DataTemplate" in the XAML causes the values in the
combobox to disappear. ***

Any ideas ?

Thanks
