CharacterCasing DataGridView VB.NET
Posted on 2013-01-03
I hope that someone can help with this issue.
I have a simple grid with three columns. I want only Column 2 (index 1) to be uppercase.
In the EditingControlShowing Event I have the following code which effectively sets the text when typing to uppercase although when clicking in Column 1 (index 0) or Column 3 (index 2) the text is capitalized before starting editing. In these columns the text that is entered when typing is lowercase once you have entered the cell although the text that was capitalized on initial entry is still capitalized. Any suggestions would be greatly appreciated.
If TypeOf e.Control Is TextBox And UlfDataGridView.Columns(Ul
DirectCast(e.Control, TextBox).CharacterCasing = CharacterCasing.Upper
Else
DirectCast(e.Control, TextBox).CharacterCasing = CharacterCasing.Normal
End If

This sounds like a problem with the TextBox control that is used for the editor, since I believe that it is shared for all the cells.
Another approach might be to attach an event handler to the KeyDown event, and convert the characters to upper case only when typing in the cell.

I realize that I could use the KeyDown event to do this but I was hoping to find an answer for doing this with charactercasing. I would assume there has to be a way.
Is there a way to set the TextBox control's charactercasing back to normal when the cell gets focus or leaving the cell (cellendedit)? I can't seem to figure out how this would be done. I am new to VB.NET programming.
The problem that I am having there is that I can't seem to reference the textbox. In other words if I tried to use the following code it will not work because e is set to ByVal e As System.Windows.Forms.DataG
DirectCast(e.Control, TextBox).CharacterCasing = CharacterCasing.Normal

Note: When I tab to any column the casing works as it should but if I click into the cell is when I have the problem shown above.

You don't really have a reference outside of the EditorControlShowing, so you would need create a module-level reference to the TextBox control that is used with that column. Then, you might be able to change CharacterCasing in the Enter event handler.
This is the code that I finally have went with. Apparently there isn't an easy way to set the CharacterCasing back to lower case before re-entering or leaving the text box.
Private Sub DataGridView1_CellValidated(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles UlfDataGridView.CellValidated
If (e.RowIndex >= 0) And (e.ColumnIndex >= 1) AndAlso (TypeOf DirectCast(sender, DataGridView).Item(e.ColumnIndex, e.RowIndex).Value Is String) Then
DirectCast(sender, DataGridView).Item(e.ColumnIndex, e.RowIndex).Value = CType(DirectCast(sender, DataGridView).Item(e.ColumnIndex, e.RowIndex).Value, String).ToUpper
End If
End Sub
My ideal approach would have been to be able to set the CharacterCasing back to lower. From comments here, reading and research it appears that this is not possible until after the user enters the control. In this case the controls/columns that I would not want in uppercase would be converted to uppercase before the user entered the text box they were editing.
