Dear Telerik!

I have a problem with RadSplitButton in RadControls for WinForms.

I have one or more RadRibbonBarGroup within some buttons and for this reason my form isn’t narrow enough, the RadSplitButton (which is in the RadRibbonBarGroup) has an error.

So when I open down the RadRibbonBarGroup than click on an item (the item open a new form) on RadSplitButton, the RadSplitButton remains open.

I attach some screenshot to show you my problem.

Is there any solution for this?

Thanks in advice!

RadGridView populate Template

Hello,
I´m working with radgridview for winforms, I'm a begginer in it, and I have a problem, I don't know how to populate the template of de grid, I try with this code:

Private

Sub rgvProgramacionEntregasCabecero_ChildViewExpanded(sender As Object, e As Telerik.WinControls.UI.ChildViewExpandedEventArgs) Handles rgvProgramacionEntregasCabecero.ChildViewExpanded

Try

'gvtProgramacionEntregasDetalle.DataSource = Obtener_DetalleViaje(rddlCentroDistribucion.SelectedValue, Today.AddDays(-30), _GrupoViaje)

Me.rgvProgramacionEntregasCabecero.Templates(0).DataSource = Obtener_DetalleViaje(rddlCentroDistribucion.SelectedValue, Today.AddDays(-30), _GrupoViaje)

End Using

Catch ex As Exception

RadMessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, RadMessageIcon.Error)

End Try

End Sub

but it doesn't work as I expected, when I expanded the principal grid, the template(or de child grid) is empty, so the function Obtener_DetalleViaje return information... I'm not shure it is the way to populate it, someone can help me?
I hope to be clear, thanks in advance

how do I know when the expression editor is closed?

I would like to be able to use the expression editor as a stand-alone component. I've been playing with both the WinForms and WPF versions.

I do realize the WinForms version doesn't directly support standalone operation, so what I've done is created a RadGridView and made it invisible. I add some columns programmatically, and enable expression editing on the first one (only).
Then I have a button which launches the expression editor:
RadExpressionEditorForm.Show(grid1, grid1.Columns[0]);

Which does bring up the expression editor, and I see the other columns I've defined in the "Fields" list.

But the method RadExpressionEditor.Show() method is not modal -- it returns immediately, and I don't see an alternate ShowDialog() signature. Also, the method returns void, so I don't know whether the user pressed Cancel or OK.

I'm guessing that what I should do is handle some event on the grid view to know when the dialog has been dismissed ... but I've tried several, including CellValueChanged() and CellEndEdit(), and they don't ever seem to get called.

What am I doing wrong?!?

Getting RecurrenceRule string from the Edit Recurrence Dialog

Hello!

I use a non-Telerik form to add/edit Appointments. I want to use Telerik's Edit Recurrence dialog instead of creating a whole new form like I did for adding/editing appointments. I want to do something like:

EditRecurrenceDialog dialog = new EditRecurrenceDialog(appointment);

dialog.Show();

I would assume that once the dialog exits, I would be able to retrieve the recurrence rule from the appointment that I passed in's RecurrenceRule property, but the dialog closes right after it opens, and then returns a null exception when I access the RecurrenceRule property since I didn't get to create a recurrence rule with the form. Any help would be appreciated! Thanks!

GirdView Export to Exel with Dynamic Data Binding

I have a RadGridView that I set the datasource at run time. When I export it all the rows that are visible on the screen export fine, however the ones you can't see the excel row height is 3.75 pixels. (See attached screen shot) How do I get the export to export the correct format of all rows not just the ones visible? One other side note is if I scroll through the list and then export it exports correctly.

this.tSQL = "EXEC dbo.GetDetailsForCodeType '" + strSelectedCode + "','" + strSelectedCodeType + "'";
DataTable dtMarketDetails = this.da.GetDataTable(this.tSQL);
this.dgMarketDetails.DataSource = dtMarketDetails;

As a test I setup another GridView and pre set the data source and that exports just fine.

Move DescriptionTextListDataItem Separator Line

I'm currently using a RadDropDownList with a set of DescriptionTextListDataItems in DropDownList mode and it looks great except that it's drawing a thin gray separator line between the item text and the item description like this:

Text

----------

Description

Text

----------

Description

Is there a way to remove this separator line and to have a separator line between the list items? What I'm looking for is something like this:

Text

Description

----------

Text

Description

I'm not sure the way I'm doing it now is correct or the preferred way.

private void SearchTypeList_CreatingVisualListItem(object sender, CreatingVisualListItemEventArgs e)

{

e.VisualItem.BorderColor = SystemColors.Control;

//e.VisualItem.Children[0].Children[1].Children[1].ShouldPaint = false;

foreach(var child in e.VisualItem.Children)

{

if(child is StackLayoutElement)

{

foreach(var child1 in child.Children)

{

if(child1 is StackLayoutElement)

{

foreach(var child2 in child1.Children)

{

if(child2 is LinePrimitive)

{

child2.ShouldPaint = false;

return;

}
