I am having a bad time with AJAX request and error message after first OnRowDeleted function call: "Multiple controls with the same ID 'ctl00' were found. FindControl requires that controls have unique IDs."
I build my radtabstrip and radpages and radgrids on pageload.
here is my code for code behind.
Here is my aspx page:
