Problem regarding to tabpanel control of ajax

Hi Kaushik,

I think you should set the CheckBox's AutoPostBack ="true", and when it is clicked , control the Tab on the server side. For example:

protected void Page_Load(object sender, EventArgs e)
{
if (!CheckBox1.Checked)
{
this.TabContainer1.Tabs.Remove(this.TabPanel1);
}
}

I hope this help.

Best regards,

Jonathan
