Hi friends,

I Have gridview by default no columns declared in the aspx page. I declared the columns dynamically based on the requirement. I have a subject dropdownlist control ,inwhich selectedIndexchanged event I created dynamic columns(label,and textbox) show in the page.. For label control I bind the data from database and for Textbox i just enter the data from here. Outside the gridview I Have the button for save this gridview value to database.In button click event i would like call the gridview data for saving in the database. But I Have an issue with gridview state level.In this button click event postback, gridview loses their data value,so i cannot able to read the data from gridview. what is my task is I want to read the gridview data to save to database. help me.

I post my code previously. but no result. i tried my level best.

Please show the Page Load Code.

protected void Page_Load(object sender, EventArgs e)
{
Button1.Visible = false;
Button2.Visible = false;
if (!IsPostBack)
{
int year = DateTime.Now.Year;
int month = DateTime.Now.Month;
DataTable acyear = inter.bindacademicyears(year,month);
// acyeardropdown.Items.Insert(0, "Select Year");
for (int i = 0; i < acyear.Rows.Count; i++)
{
acyeardropdown.Items.Add(acyear.Rows[i]["FromYear"].ToString() + "-" + acyear.Rows[i]["ToYear"].ToString());

}
bindmedium();

I have created the gridview columns dynamically in the subjectdropdown_selectedIndexChanged event not in the page_load event. and my gridiew has editable textbox control. in that i enter mark then only i pass this grid in the another button click event.
