Cellvalue doesn't retain while editing for dynamically added columns

Hi

I am using TreeListView.
I am adding columns dynamically at runtime

GridViewDataColumn column;

for (int icnt = 1; icnt < ts.Days; icnt++)

{

column = new GridViewDataColumn();
column.UniqueName = "key" + icnt.ToString();
column.IsReadOnly = false;
RadTreeListView1.Columns.Add(column);

}

I am populating the cell data in RadTreeListView1_RowLoaded event.

var row = e.Row as TreeListViewRow;

foreach (GridViewCell cell in row.Cells)

{

if (cell.IsLoaded)
{

DateTime dates;

if (DateTime.TryParse(cell.Column.Header.ToString(), out dates))
{

string filter = "dates = '#" + dates.ToShortDateString().ToString() + "#'";

DataRow[] dr = lobjdt.Select(filter);

if (dr != null && dr.Length > 0)

{

cell.Content = dr[0]["hours"].ToString();

}

}

But I am facing one more diffrent problem.
I want to edit cells of cloumns which I have added dynamically.
I am able to click and edit the data ... but data gets disappeares when user leave the cell and click somewhere else in the window.

Editing is working correctly in static clumns.
Am I missing anything while adding columns ?

Focus on particular Row (child node) on page load.

Hi Telerik Team,

I am working on TreeViewList. When page is loaded, the default focus goes to first parent node. Can I set focus on a particular row (child node) on PageLoad? So that user will not need to drill down to that row.

Custom Theme for the GridView

There is a 'tutorial' in the RadGridView documentation that I was attempting to follow: http://www.telerik.com/help/silverlight/how-to-create-a-custom-theme.html

It mentions: "Every theme of RadGridView contains a file called Resources.xaml. This file contains the Brushes and Colors used by RadGridView. The brushes share the colors defined in this file. "

I looked around for these Resources.xaml theme files but was unable to find them. If someone could elaborate on how to go about modifying a theme that would really help me out.

Thanks,
Ryan

Problem with ExportToImage

Hi. We try to get screenshot of chart control in STA thread. The workaround of removing transparency in style is used. But some charts are not displayed yet. Especially Horizontal Bar and Stacked Bar cannot be exported (there are scales only) while bar chart can be exported perfectly. If you want I can send a demo project I've created.
Is there any workaround? Thanks in advance.

Deleting item in the tree list hierarchy

Hi,
I'm trying to delete an item in the tree hierarchy.

       private void ButtonRemove_Click(object sender, RoutedEventArgs e)
        {
            if (DialogRadTreeListView.SelectedItem != null)
            {
                DialogRadTreeListView.Items.Remove(DialogRadTreeListView.SelectedItem);
 
            }
 
        }

I believe the above code only deletes if the SelectedItem is in the first level of DialogRadTreeListView.Items.
If SelectedItem is several levels deep, "Remove" won't find it.
Any ideas how I can delete an item in this case?

Thanks.

-Chris

Virtualization of hierarchy child rows

I noticed that rows of hierarchy child aren't virtualized. So If I have a child table with 500 rows, 500 UI controls will be generated for each of the rows. You can use Snoop to see that. (Rows of root table, at the top of the hierarchy are virtualized, as expected).

Is there a way to extend virtualization to support child tables? If not, is there a plan to support it in the future?
