How to get the selected item value from the legend using c#.net

[Chandu]

Hi Friends, 

I have the telerik rad chart,  when i click on  specific item in the Legend it has to redirect to other page with selected item id with query string, can you please help me for this.

Ex: default.aspx?id=io# 1388249 or  default.aspx?id=io# 1389656

Thanks in advance

Hello Chandu,

Achieving this functionality is not possible using C# alone. You will have to modify the Attributes property of each legend item by attaching JavaScript code:

void RadChart1_BeforeLayout(object sender, EventArgs e)
{
    foreach (var item in this.RadChart1.Legend.Items)
    {
        item.ActiveRegion.Attributes = "onclick='self.location=\"http://www.telerik.com/\"'";
    }
}

You can then easily modify the redirect URL to suit your own needs. Note that the BeforeLayout event is when you can access the legend's items at earliest.
