My user amends text in a datagrid. When this happens i want a Save button
that currently has enabled set to false to become enabled.

I have been messing around with the CurrentCellChanged event, however this
activates the button just by clicking within the grid.
I want the button to only become enabled when text within the grid is
changed.

How can i do this?.....

many thanks in advance.

Hi,

      First add a tablestyle to the datagrid then I would add a handler to
the datagridtextboxcolumns textbox textchanged event.

Add Tablestyle

Add a handler to textchanged event

Dim colName As New DataGridTextBoxColumn

With colName

.MappingName = "LastName"

.HeaderText = "Name"

.Width = 100

End With

AddHandler colName.TextBox.TextChanged, AddressOf TextBox_TextChanged

Private Sub TextBox_TextChanged(ByVal sender As Object, ByVal e As
System.EventArgs)

'Enable button here

End Sub
