RadCheckedDropDownList in RadGridView - writing selections back to database

Hi Curtis,

I am assuming that you are using the approach demonstrated in the Use as RadGridView editor help article. In your case, you can subscribe to the CellValueChanged event which will be called when the cell value is changed. In your case, when you close the editor of the cell, the event handler will be called.

private void RadGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
{          
    if (e.ColumnIndex == 0) // mu column with RadCheckDropDownList
    {
        var value = e.Value;
    }
}

For updating the database, you can check the Updating the Database with ADO.Net which describes a possible approach. In your case, you can check the last section in the article: Updating the database when a single cell value is changed
