You have two options for handling row header clicks:
1. Hyperlink
The following code will render a hyperlink in the resource header:
protected void DayPilotScheduler1_BeforeResHeaderRender(object sender, DayPilot.Web.Ui.Events.BeforeHeaderRenderEventArgs e)
{
if (!e.IsCorner) // don't modify the upper-left corner
{
if (!DayPilotScheduler1.IsExport) // required if you are using PNG Export
{
e.InnerHTML = String.Format("{1}", e.Value, e.Name);
}
}
}
2. ResourceHeaderClick event
You can handle that event using PostBack:
ResourceHeaderClickHandling="PostBack"
or JavaScript:
ResourceHeaderClickHandling="JavaScript"
CallBack handling doesn't make much sense here, you wouldn't be able to redirect to another page.
