Hello,
I would like to have in my gridView a delete button(no commandButton) for each row added.
When i clicked on one of this buttons, i would like the corresponding row to be deleted.

This is what it does:
ICreate the button on cellFormatting and add an eventHandler

    
             Private Sub GridViewPrepack_CellFormatting(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles GridViewPrepack.CellFormatting 
        
                      If Not (e.CellElement.Children.Count > 0) Then  
        
                                Dim myButton As New RadButtonElement 
        
                                'Display style of the Image 
        
                                if  CType(e.CellElement.ColumnInfo,GridViewDataColumn).FieldName = "Delete" 
        
                                        AddHandler myButton.Click, AddressOf DeleteButton_Click 
        
                                        'add the button to the cell 
        
                                        e.CellElement.Children.Add(myButton) 
        
                            End If 
        
                        End If 
        
                End Sub

Now, i would like the row to be deleted when the delete button is clicked, but i don't know how.
I tried this, but it doesn't delete the right row

    
             Private Sub DeleteButton_Click(ByVal sender As Object, ByVal e As EventArgs) 
        
                    GridViewPrepack.Rows.Remove(GridViewPrepack.CurrentRow) 
        
                End Sub

.
can you help me?
Thank you

ShowParentGroupSummaries don't update

Dear Support,

We use RadGridView with Summaries rows and Parent Summaries rows. On loading all sum are correct. But when the user change a value in the grid, the summaries are updated but not the parent summaries rows.

I attached pictures showing the problem. AfterLoad is the gris after the form is loaded, and afterChange is the gris when I change the value of the first row from 75 to 65. Top Summaries and group summaries have updated but not the parent summaries.

Please advise,
Nadia

DropDownList size/length/displayed item count (Solution)

Hello,

I looked sometimes for a solution to change the count of items displayed in the Popup of the RadDropDownListEditorElement.

My solution now is:

Use of EditorRequired event from RadPropertyGrid, Setting the editor to RadDropDownListEditor. Getting the EditorElement as RadDropDownListEditorElement and define the MinSize of Popup as follows:

RadDropDownListEditor editor = new RadDropDownListEditor();

RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;

element.Popup.MinimumSize = new System.Drawing.Size(element.Popup.MinimumSize.Width,

element.ItemHeight * 10);

editor.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

e.Editor = editor;

where as 10 ist the count of items to be displayed.

Regards from Leipzig

Delete Button in Gridview Doesn't fire UserDeletingRow event?

Hello guys i have a problem regarding my RadButtonElement.
I have this RadButtonElement inside my GridViewCommandColumn.
here is my Code:

Private Sub rgvSKUDetails_CommandCellClick(sender As System.Object, e As System.EventArgs) Handles rgvSKUDetails.CommandCellClick

If TypeOf rgvSKUDetails.CurrentRow Is Telerik.WinControls.UI.GridViewNewRowInfo Then

Exit Sub

End If

rgvSKUDetails.Rows.RemoveAt(rgvSKUDetails.CurrentRow.Index)

End Sub

I was Expecting that this CommandcellClick event will fire the.

Public Sub rgvSKUDetails_UserDeletingRow(sender As System.Object, e As Telerik.WinControls.UI.GridViewRowCancelEventArgs) Handles rgvSKUDetails.UserDeletingRow

Msgbox("Why Did you delete it?"

)

'This section here, im supposed to update the database that the 

record has been deleted, but since this event is not firing is 

there anyway that i could capture the event so i could update the database 

that the user deleted the record?

'Perform Update to database

End Sub

i needed it because i want to update the database that the particular row was deleted by the user.

Thanks IMO
