I want to maintain the checkbox state with in a gridview while using ajax tab container in asp.net with c#. I have checked a checkbox with in the grid but checked state is coming as false.
I am using the activetabindex changed event with Auto post true of the ajax tab container but check box state in the grid even if checked coming as unchecked.

What I have tried:
In the active tab index changed even on checking the checkbox in the grid checkbox state coming as false.
List<OUT_500_DETAIL> ListDashboard = new List<OUT_500_DETAIL>();
if ((List<OUT_500_DETAIL>)ViewState["RepEnvelopeGrid"] != null)
{
ListDashboard = (List<OUT_500_DETAIL>)ViewState["RepEnvelopeGrid"];
}
OUT_500_DETAIL objDashboard;
int index = -1;
for (int i = 0; i < grdRepresentment.Items.Count; i++)
{
objDashboard = new OUT_500_DETAIL();
objDashboard.OUT_500_FileDetailID = Convert.ToDecimal(((HtmlInputHidden)grdRepresentment.Items[i].FindControl("hidDetailId")).Value);
objDashboard.RemarksByBC = ((TextBox)grdRepresentment.Items[i].FindControl("TxtReason")).Text.ToString();
CheckBox chkEnvelopeSelect = (CheckBox)grdRepresentment.Items[i].FindControl("chkRepEnvelopeSelect");
if (chkEnvelopeSelect != null)
{
try
{
index = ListDashboard.Select((item, k) => new { Item = item, Index = k }).First(x => x.Item.OUT_500_FileDetailID == objDashboard.OUT_500_FileDetailID).Index;
}
catch
{
}
if (index != -1)
{
ListDashboard.RemoveAt(index);
}
if (chkEnvelopeSelect.Checked)
{
ListDashboard.Add(objDashboard);
}
index = -1;
}
}
ViewState["RepEnvelopeGrid"] = ListDashboard;
