Ajax tab pages navigation failed

Question

 Hi friends,

            I have added ajax tab container in my web page. that has two tab pages. when i click my first  tab page button  i want to save the value of the first tab control values and automatically  the second tab need to be open. i tried the following code but it did not open. 

 

bool result = bil.InsertBuyer(buyer);

if (result)

{

// BuyerEntry.TabContainer1.ActiveTabIndex = 1;

// Response.Redirect("~/BuyerList.aspx?value" + 1);

// BuyerEntry.TabContainer1.Tabs[0].Visible = false;

BuyerEntry.TabContainer1.ActiveTab = BuyerEntry.TabContainer1.Tabs[1];

BuyerEntry.TabContainer1.ActiveTabIndex++;

BuyerEntry.txtbid.ReadOnly = true;

BuyerEntry.txtname1.ReadOnly = true;

BuyerEntry.txtbid.Text = buyer.BUYERID;

BuyerEntry.txtname1.Text = buyer.BUYERNAME;

}

in the above code I insert the value using InsertBuyer method. then if inserted I want to open the next tab.
