I am using Ajax tabcontainer and repeater to bind the data and also some other fields like session values. All are working fine but when comes to button click whether it is asp.net button or HTML button or link button or imagebutton or any other buttons available i have tried all those buttons in that binded page. Those buttons are not firing at all please anybody help me regarding this issue.

What I have tried:

In Page load
Label.Text = Session["Object"].ToString();
Label1.Text = Method().ToString(); // <-- This method is used get the details and append to asp.net label
int count = Convert.ToInt32(Method1()); // <-- This method1 is used to count the details
hdnCount.Value = count.ToString();
// It is used to get the details from database
// and binds to Dataset to create AjaxTabPanels
BuildDataSet();
// This is used to fetch the details from the database
// and creates the tabpanel for ajax tabconatiner
AddTabPanels();

Solution 1

Here are my suggestions:

(1) Have you tried setting a break point at your Button Click events to see if it hits there?

(2) I'm not a fan of UpdatePanel control, but can you try removing the ChildrenAsTriggers="false" in your UpdatePanel control?

Show us the relevant codes that causes this error. Which line in your code throws the error?

Also, I didn't ask you to remove the UpdatePanel completely. Just the ChildrenAsTriggers attribute.

Member 8583441 11-Dec-18 1:53am

I have removed ChildrenAsTriggers attribute but no use

Vincent Maverick Durano 11-Dec-18 7:08am

So which line the error occurred?
