Are these 2 events gone from the control ?

I can not use this anymore since I've upgraded to Q2... And I do not find anything about this in the release docs...

Hi Stargazer,

We did a major revamp of RadGridView editors system. Now, all editors in grid inherit BaseGridEditor class, which is not a RadElement. You can access the underlying editor element by using the EditorElement property. Here is a sample:

void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e) 
    RadTextBoxEditor editor = this.radGridView1.ActiveEditor as RadTextBoxEditor; 
    if (editor != null
    { 
        ((RadTextBoxItem)editor.EditorElement).KeyDown += new KeyEventHandler(Form1_KeyDown); 
    } 
 
void  radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e) 
    RadTextBoxEditor editor = this.radGridView1.ActiveEditor as RadTextBoxEditor; 
    if (editor != null
    { 
        ((RadTextBoxItem)editor.EditorElement).KeyDown -= new KeyEventHandler(Form1_KeyDown); 
    } 
 
void Form1_KeyDown(object sender, KeyEventArgs e) 
    //...     

I hope this helps. If you have more questions, don't hesitate to write us back.

Hello, good morning!

I eventually was able to figured it out last Saturday, with the difference that I used RadTextBoxEditorElement, but had no access to the internet to post it.

Thanks!

Hello 

I tried to put the below code :

Private Sub radGridView1_CellBeginEdit(sender As Object, e As GridViewCellCancelEventArgs) Handles RadGridView1.CellBeginEdit
        Dim editor As RadTextBoxEditor = DirectCast(e.ActiveEditor, RadTextBoxEditor)
        If Not IsNothing(editor) Then
            Dim editorElement As RadTextBoxEditorElement = DirectCast(editor.EditorElement, RadTextBoxEditorElement)
            AddHandler editorElement.KeyPress, AddressOf KeyPresses
        End If
    End Sub

 Private Sub KeyPresses(sender As Object, e As KeyPressEventArgs)
        If Asc(e.KeyChar) <> 8 Then
            If ((Asc(e.KeyChar) < 48 Or Asc(e.KeyChar) > 57) And Asc(e.KeyChar) <> 46) Then
                e.Handled = True
            End If
        End If
    End Sub

but I'm able to insert alphanumeric for the first character, then it just let me enter an integer.
there's solution to just enter numeric for specific cells ?

Thanks

I've run into the same depricated code examples online that don't work.  Basically I'm trying to get a radgrid to behave more like Excel with respect to the up/down keys.  The GridSpinEditor is preventing this I think.  Do you have a code example showing how to get the grid to move from cell to cell in the verticle direction (with the up/down arrow keys).  VB.net Winforms.

Hi Mark,

The grid moves up/down with the arrow keys, when there is no cell opened for edit. When such is opened, the editor will handle the keyboard (if needed), so the spinner or the date time picker can change their values. 

Please refer to the following post of mine, where I have provided an example how to prevent value change of the spin editor with the arrow keys, and move the row selection instead: http://www.telerik.com/forums/gridviewdecimalcolumn-up-down-key#yaJobaxmWEyB16Qaub1Zww
 
I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
