Imports C1.Web.Command
• C#
using C1.Web.Command;
3. Enter the following code in the Page_Load procedure to open the URL in a new window when you click on the first group in the Topic Bar:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Assign the variable name to the first group
Dim group1 As C1WebTopicBarGroup = CType(C1WebTopicBar1.Groups(0),C1WebTopicBarGroup)
'Assign the text name for the first group
group1.Text = "Group 1"
'Assign the C1WebGroupHeader.ClientScripts property to execute the client side script when you click on the group
group1.ClientScripts.Add(New ScriptDef("onclick", "alert('You clicked on Group 1');"))
'set the EnableExpandCollapse to false to prevent the group from collapsing when you click on the header
group1.EnableExpandCollapse = False
End Sub
• C#
protected void Page_Load(object sender, EventArgs e)
{
C1WebTopicBarGroup group1 = (C1WebTopicBarGroup)C1WebTopicBar1.Groups[0];
group1.Text = "Group 1";
//Assign the C1WebGroupHeader.ClientScripts property to execute the client side script when you click on the header
group1.ClientScripts.Add(new ScriptDef("onclick", "alert('You clicked on Group 1');"));
//this will prevent the group from collapsing when you click on the header
group1.EnableExpandCollapse = false;
