i updated my question

private void Subjectbind(string ExamYear, string ExamType)
{

if (ddlExamYear.SelectedIndex == 0)
ExamYear = ddlExamYear.SelectedValue;
if (ddlExamType.SelectedIndex == 0)
ExamType = ddlExamType.SelectedValue;




List<spgetexamtypecourses_result> lstCourses =
objMDLClass.GetAllExamTypeCourses(Convert.ToInt32(ExamType),
ExamYear);
objManage = new StudentManage((Users)Session["user"]);


foreach (SpGetExamTypeCourses_Result objCourse in lstCourses)
{

GridTemplateColumn col = new GridTemplateColumn();
col.UniqueName = objCourse.CourseId.ToString();
col.HeaderText = objCourse.CourseName;
col.ItemTemplate = new GridCustomItemTemplate(objManage.GetExamAnalysisReport(
Convert.ToInt32(objCourse.CourseId), Convert.ToInt32(ExamType),
ExamYear));



gvSubwisePerformance.MasterTableView.Columns.Add(col);

}
gvSubwisePerformance.Rebind();
}
i used this method and i called this method in ispostback method so that if drop down value changes this method is executed automatically.

i got the result for the first time page load.

But i have a dropdown when the dropdown value changed the grid also must be updated .
when i am changing the drop down value the data is coming but the grid is not visible

dynamic grid view loses binding when post back occurs ?

I have a dynamic grid View with template fields and bound fields as columns

for the first page load all binding looks fine.values are populated in all columns

when I trigger an event such as selected index changed in Drop downlist present in the column header(inside template field ) the binding are lost and the event is never catched.

how to retain controls when post back occurs and how to resolve this problem ?

i got the columns and my grid view is binding successfully in first postback event but if again the post back occurs the gridview is not visible
can any one help me?

oh ok thank you

No i Want it in regular expression only
Anyway thank you
