Problems with inherited form with control RadTabStrip

Hi,

I have created the template form with the control RadTabStrip. When the other form inherites from the template, I can’t add more TabItems in design time, because it fails. The errors are:

Element already added!
Hide

at Telerik.WinControls.RadElementCollection.CheckElementAlreadyAdded(Object value)
at Telerik.WinControls.RadElementCollection.OnInsert(Int32 index, Object value)
at System.Collections.CollectionBase.System.Collections.IList.Insert(Int32 index, Object value)
at Telerik.WinControls.RadItemCollection.OnInsertComplete(Int32 index, Object value)
at System.Collections.CollectionBase.System.Collections.IList.Add(Object value)
at Telerik.WinControls.RadItemCollection.AddRange(RadItem[] value)

But if i comment the line

this.radTabStrip1.Items.AddRange(new Telerik.WinControls.RadItem[] {

this.tabItem2});

and change it for

this.radTabStrip1.Items.AddRange(new Telerik.WinControls.RadItem[] {

new Telerik.WinControls.UI.TabItem()

});

there is no error. In run time it doesn´t present this error.

RadToggleButton and RadTrackBar ToolTipText

I tried to add a tooltiptext to RadToggleButton and RadTrackBar.
The code is below:

toggleButtonMagnifier.RootElement.ToolTipText = "Magnification Toggle";
toggleButtonMagnifier.ShowItemToolTips = true;

Also tried the other way:
((RadMenu)AttachmentView.Controls[1]).MenuElement.Items[0].ToolTipText = "Magnification Toggle";

but tooltiptext did not pup up.

Any suggestion?

Thanks,

Susan

ShapedForm.StartPosition

I am creating a shaped form as a DialogResult:

Dim Result As DialogResult = frmShapedForm.ShowDialog(Me) 

In my frmShapedForm.designer.vb, I am specifying:

Me.StartPosition = FormStartPosition.CenterParent 

to center the form atop the parent (opener) form but it is not working, when i change the form to inherit from Windows.Forms.Form, everything works as expected.

Completing an edit without changing rows

Hi,

I have a grid bound to a list of custom objects. The first column is a GridViewBoolean Column. When a user clicks on the check box I would like the value immediatly reflected back into the underlying data source rather then having to change rows for it to be commited.

Is this possible?

Thanks.
