Validation groups in User Controls
Found a neat way of enabling validation groups in user
controls.
http://aspalliance.com/1741_Video_Using_ValidationGroup_Control_with_User_Controls
I made a slight change for this to work with panels. Had to iterate through
child controls to get the ValidationGroups set correctly.
using
System;
using
System.Reflection;
using
System.Web.UI;
public class BaseUserControl : UserControl
{
public
BaseUserControl()
{
this.Load += new EventHandler(BaseUserControl_Load);
}
void BaseUserControl_Load(object sender, EventArgs e)
{
AssignValidation(this);
}
public string ValidationGroup
{
get { return (string)ViewState["ValidationGroup"]; }
set { ViewState["ValidationGroup"] = value; }
}
protected void AssignValidation(Control ParentControl)
{
foreach (Control control in ParentControl.Controls)
{
AssignValidation(control);
PropertyInfo property =
control.GetType().GetProperty("ValidationGroup");
if (property == null) continue;
property.SetValue(control, ValidationGroup, null);
}
}
}
