For a project, i need to resize ToolWindows when they are floating, and are at a certain position at the screen, but the onlocationChange event isn't fired when I move the floating window on the screen

It is fired  before i make the window floating.

I'm using the 2010 Q2 SP1 release.

Hi,

I would like to cancel an edit in the RadGridView as soon as the user clicks another row (or when the grid loses focus).
In the CurrentRowChanged Event i call Grid.CancelEdit but it always returns false and the new row is still in Edit-mode after that.

I found the ActionOnLostFocus property in the knowledgebase but that's for Silverlight and i couldn't find that property for WinForms.

Any ideas on how to get the canceledit working?

Hi Telerik Team,

Please advice if I can change the background colour of Filtering Row in RadGridView, if so then how can I do that. I just want to do that to make it stand out from other rows in the grid.

Many thanks,

Sheraz

This is probably a very dumb question.

Hi:

I have a strange problem that I could solve and it's driving me nuts!

I have dynamically added a Lookup column to my grid during form load:

    c = New GridViewLookUpColumn("ColFinalGrade_Manual", "FinalGrade_Manual")
    c.ValueMember = "GdRule_GradeCode"
    c.DisplayMember = "GdRule_GradeCode"
    c.DataSource = ds_Gd.Tables(0)
    RGV_StdEnrl.MasterGridViewTemplate.Columns.Insert(RGV_StdEnrl.Columns.Count - 1, c)

Then during CellBeginEdit of the grid, I have the following codes (except from longer codes)

    If RGV_StdEnrl.Columns(e.ColumnIndex).UniqueName = "ColFinalGrade_Manual" Then
        Dim editor As IInputEditor = Me.RGV_StdEnrl.ActiveEditor
        If Not editor Is Nothing AndAlso TypeOf (editor) Is RadComboBoxEditor Then
            Dim comboElement As RadComboBoxElement = CType(CType(editor, RadComboBoxEditor).EditorElement, RadComboBoxElement)
                            For I As Integer = 0 To comboElement.Items.Count - 1   (!!!!!PROBLEM IS HERE!!!!)
                                If comboElement.Items(I).Text = "" & RGV_StdEnrl.MasterGridViewTemplate.Rows(e.RowIndex).Cells("ColFinalGrade_Manual").Value Then
                                    comboElement.SelectedIndex = I
                                    Exit For
                                End If
                            Next
    . . .

The problem is:  The item count for comboElement is ALWAYS 0 when I click on that particular cell FOR THE FIRST TIME after the form is loaded. So, the correct value never gets selected.  In fact, during the FIRST run of CellBeginEdit, the DataSource for the comboElement is ALWAYS Nothing.  There is nothing I could do to change that. EVEN IF I first test for it begin nothing and then try to assign it a datasource at that time (If comboElement.DataSource Is Nothing Then comboElement.DataSource = theTable), the item count for the comboElement remains 0.  It almost as if it doesn't want to take anything. No error is generated either.

The strangest part is: This problem only happens ONCE every form load (the very first time that cell is click).  After that, the above code works exact as it should.

I'm just stumped, and would appreciate some help on this.

Thanks!

I have a check box column in a RadGridView, and I can't seem to make it read only.  I've searched through the forums, and only found people with the opposite problem.  I've seen posts about people with read only grids where they want one column editable.  What I want is a checkbox column that is NOT editable, but try as I might, you can edit the check boxes in this grid.

I set the grid's ReadOnly property to True.
I set the individual column's ReadOnly property to True.
I set the grid's AllowEditRow to False.
I even set the grid's BeginEditMode property to BeginEditProgrammatically.

Nothing has any effect.  What do I have to do to make a simple read-only grid?

Is there something I'm missing... I have the Ribbonbar with the Office2007Black theme.  I set the tab shapes to TabVsShape and I can see it at design time.  However, the tabs are still rectangular at run-time.  What am I missing?
