Asp.Net - Make short ids for controls

Here is a code for making your controls names/ids shorten than it is, because asp.net as default make every control name: {parent-id}_{control-id} and it makes html code length larger...


public class BasePage : Page
{
protected override void OnInit(EventArgs p_eventArgs)
{
MakeIdsShorted(this, true);
base.OnInit(p_eventArgs);
}

private int currentId = 0;
private void MakeIdsShorted(Control p_ctrl, bool p_recursive)
{
if (p_ctrl is Login)
{
return; // ignore ASP.Login controls
}
if (string.IsNullOrEmpty(p_ctrl.ID) == false)
{
//this.EnsureID();
p_ctrl.ID = "c" + currentId; // p_ctrl.ID.GetHashCode();
currentId++;
}

if (p_recursive == true)
{
foreach (Control c in p_ctrl.Controls)
{
MakeIdsShorted(c, true);
}
}
}
}



Make sure your created page is inherits from BasePage...
