DataGrid Checkbox Event capture
-
Hi All, I have a C# Windows Form, which contains a DataGrid, and one of the column in the DaatrGrid is Checkbox. What I need to do is - when checkbox is checked, all other checkboxes should be unchecked. For ex: if there are 10 rows in DataGrid, and Row - 2 has checkbox checked. Now when "Checkbox column of Row - 5" is clicked, it should un-check "Checkbox column of Row - 2" . Please let me know how can I capture check_event and loop through all rows. Any help or pointers :confused: Thanks in Advance :rolleyes: Ruchi

Actually, it's not a
CheckBox. A check box is merely drawn by theDataGridBoolColumnusing eitherControlPaint.DrawMixedCheckBoxorControlPaint.DrawCheckBox, depending on whether or not the column allows nulls (DBNull). If you want to use an actualCheckBoxand expose the event (better to encapsulate theCheckBoxand expose only what's needed), you'll have to derive your ownDataGridColumnStyle. See the documentation for that class in the .NET Framework SDK, which also includes a sample using aDateTimePickercontrol.Microsoft MVP, Visual C# My Articles

Oh, I almost forgot: if you're using a
DataSetorDataTablefor binding, you can handle theDataTable.ColumnChangingorDataTable.ColumnChangeedevent and then enumerate theDataRows in the `DataTable` and change what you need accordingly.
