color the background of a cell

[Shirya]

Hello,
Could you help me with this:
When a cell is selected in my grid, i would like its backcolor to change to "Selected color".
And when another cell is clicked, the previous cell change its backColor to "Original color".

All of this is working when I  insert this code:

Private Sub GridViewPrepack_CellClick(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles GridViewPrepack.CellClick

'Get the right cell and the columnName

Dim myNewSelectedCell = CType(sender, GridCellElement)

Dim columnName As String = myNewSelectedCell.ColumnInfo.HeaderText

GridViewPrepack.CurrentRow.Cells(columnName).CellElement.BackColor = Color.Red

End Sub

 
Here is what i don't know how to do:
There is a commandCell in my grid, and I when i click on it, i want the color of my previous selected cell to stay to "Selected color"
I try to put a condition saying : " if its the command cell, leave my previous selected cell colored"
But it doesn't work.
Can you tell me how to do it?
thank you

Hi Shirya,

Thank you for your question. Please see the code snippet below. If you click on a command button it sets the current row to the previous current row:

Private Sub radGridView1_CommandCellClick(ByVal sender As Object, ByVal e As EventArgs)
    Me.radGridView1.CurrentRow = oldRow

End Sub
Private oldRow As GridViewRowInfo
Private Sub radGridView1_CurrentRowChanged(ByVal sender As Object, ByVal e As CurrentRowChangedEventArgs)
    oldRow = e.OldRow
End Sub

Do not hesitate to write me back if you have more questions.

hello,
thank you for the answer, but i don't know if the solution you suggest can help me.
I try to use your code , replacing the currentRow by currentCell, but it is ReadOnly...
I want to change the currentCell( when its a commandCell) to the previous currentCell.
how can i leave the backColor of a cell to red, when the next Cell clikced is a commandCell?
i hope i'm clear (sorry for my english)
thank you
Shirya

Hello Shirya,

Sorry for misunderstanding you.

Does the code below cover your scenario:

private void radGridView1_CommandCellClick(object sender, EventArgs e)
        {
            GridCommandCellElement commandCell = (GridCommandCellElement)sender;
            commandCell.BackColor = Color.Red;
            commandCell.DrawFill = true;
        }
        GridViewColumn currentColumn;

        private void radGridView1_CurrentCellChanged(object sender, Telerik.WinControls.UI.CurrentCellChangedEventArgs e)
        {
            if (e.NewCell != null && e.NewCell is GridCommandCellElement)
            {
                this.radGridView1.CurrentColumn = currentColumn;
            }
            currentColumn = this.radGridView1.CurrentColumn;
        }

Do not hesitate to write me back if you have more questions.
