In my grid view I use SaveLayout() /LoadLayout() to save the grid's configuration.

I group my grid by one column, and call SaveLayout(). Later, when I call the LoadLayout() method, the grouped column appears above the other ones, as expected, but the rows in the grid are not grouped. 

I'm enclosing two screen dumps to show the problem. 

(I use the Q3 version)

Have run the install WinForms application.

Cannot seem to find and reference to setting up the Visual Studio 2008 Pro Toolbox -- i.e. so I can drag and drop the controls needs on various WinForms etc.

Thoughts on this, much apprieated :-)

Is there some obvious explanation for this that I'm missing?
I'm experiencing what seems like control events being shared, perhaps by using a shared datasource.

I have a form with a RadListBox where the user can select an item in the listbox, and it loads details on the right. This is done by handling the listbox's SelectedIndexChanged event.

Now I'm transitioning to using a RadGridView instead so I can display extra information about the items.
To get it started, I simply added the grid to the form, added the necessary display columns, and without changing anything else, bound the grid's datasource to the same as the list. (No events set up on the grid yet. I just want to make sure the datasource is providing the information I need.)

What's weird though, is that selecting an item in the Grid ALSO selects that item in the listbox. The Listbox's SelectedIndexChanged event fires, and the sender is the Listbox (NOT the Grid, though I've only interacted with the Grid.)

The only thing that seems to 'link' the two controls basically looks like this:

form_Load(...) {
 // MyFactory.AListObject gets a List<display_object> from a data factory.
 // display_object is a simple object with a handful of display-able properties, no actual 'logic' in it.

  myListBox.DataSource = MyFactory.AListObject;
  myGrid.DataSource = MyFactory.AListObject;
}

Any idea why the grid's events are getting sent to the listbox?

P.S.
I'm currently using the Q2 controls.

I am working on a localization provider for the Radscheduler. 

I have translated the values of the comboboxes but now the texts in the comboboxes are unsorted. 

Is it possible to re-sort the comboboxes after applying a localization provider ? 

Kind Regards,

Ramius

Hi,

I'm creating an application that will allow users to drag and drop files from Windows explorer into a RadTreeView.  I have been unable to highlight a node as a drop target when a file is dragged over it.  Is this possible?

Ideally I would like to determine which node the user is hovering over when dragging the file, hightlight the node and change the drop icon to either an allow or disallow icon depending on the node tag.

Many thanks,

Joe

Control version: RadControls for WinForms Q2 2007

I created a theme for my labels to have the following property:
<?xml version="1.0" encoding="utf-8"?>
<XmlTheme xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" ThemeName="TestTheme">
  <BuilderRegistrations>
    <XmlStyleBuilderRegistration BuilderType="Telerik.WinControls.DefaultStyleBuilder">
      <StylesheetRelations>
        <RadStylesheetRelation ElementType="Telerik.WinControls.RootRadElement" RegistrationType="ElementTypeControlType" ElementName="" ControlName="" ControlType="Telerik.WinControls.UI.RadLabel" />
      </StylesheetRelations>
      <BuilderData xsi:type="XmlStyleSheet">
        <PropertySettingGroups>
          <XmlPropertySettingGroup>
            <PropertySettings>
              <XmlPropertySetting Property="Telerik.WinControls.VisualElement.Font" Value="Arial, 9pt, style=Bold" />
              <XmlPropertySetting Property="Telerik.WinControls.VisualElement.ForeColor" Value="ActiveCaption" />
            </PropertySettings>
            <Selectors>
              <XmlTypeSelector ElementType="Telerik.WinControls.UI.RadLabel+RadLabelRootElement" />
            </Selectors>
          </XmlPropertySettingGroup>
          <XmlPropertySettingGroup>
            <PropertySettings />
            <Selectors>
              <XmlTypeSelector ElementType="Telerik.WinControls.UI.RadLabelElement" />
            </Selectors>
          </XmlPropertySettingGroup>
        </PropertySettingGroups>
      </BuilderData>
    </XmlStyleBuilderRegistration>
  </BuilderRegistrations>
</XmlTheme>

When I selected my customized theme for the label, it defaulted back to the original setting. Please advise

If your ComboBox column does not display values until you edit one of the values, check to make sure you populated the DataSource of the ComboBox before populating the DataSource of the Grid.
// BAD 
gridBindingSource.DataSource = _Repository.GetGridData(); 
comboBindingSource.DataSource = _Repository.GetComboData(); 
 
// GOOD 
comboBindingSource.DataSource = _Repository.GetComboData(); 
gridBindingSource.DataSource = _Repository.GetGridData();

We just installed Winforms Q3 2009 and are noticing a problem.

We added a Treeview to a new application and ran the following two lines.

RadTreeView1.Nodes.Add("test")
RadTreeView1.Nodes.Clear()

The problem we are seeing is that after running this, the 'test' node still shows on the screen.
It seems that we are able to delete additional nodes, but that we are not able to delete the last node.
