Grid View for ASP.NET Web Forms - How to customize command buttons in individual rows

This example demonstrates how to hide or disable a command item (button or checkbox) in the grid's command column.

To do this, handle the CommandButtonInitialize event. This event is raised for each built-in command button. In the event handler, use the e.ButtonType property to determine the button type. Then, depending on the ButtonType property value, use the e.Visible to hide the button or use the e.Enabled property to disable the checkbox.

protected void ASPxGridView1_CommandButtonInitialize(object sender, DevExpress.Web.ASPxGridViewCommandButtonEventArgs e) {
    bool isOddRow = e.VisibleIndex % 2 == 0;
    if(isOddRow) {  // some condition
        // hide the Edit button
        if(e.ButtonType == DevExpress.Web.ColumnCommandButtonType.Edit)
            e.Visible = false;

        // disable the selection checkbox
        if(e.ButtonType == DevExpress.Web.ColumnCommandButtonType.SelectCheckbox)
            e.Enabled = false;
    }
}
