1. created dynamic tabs in tabcontainer,
2. when i click a button first time it works ok, but when i click it on second time i shows following error message.
3. Specified argument was out of the range of valid values. Parameter name: value
Though you have not shared the related code snnipet, above three things suggest that your dynamic tabs are not constructed during second click. This leads to the error when you try to access a particular tab/control using an index.

Make sure you build the tab on postback for proper reference. Further, put a check if the count is correct before accessing anything in the control array.
