Add the following CSS styles to remove borders in RadMenu
<style type="text/css">
/* Rootmenu items */
.RadMenu .rmRootGroup
{
border: none !important;
}
/* Submenu items */
.RadMenu .rmGroup
{
border: none !important;
}
</style>
We use Session and ArrayList to save the selected rows
public ArrayList arrayList = new ArrayList();
Convert "Session" to "ArrayList" for easy manipulation
protected void SessionToArrayList()
{
if (Session["selectedRows"] != null)
{
arrayList = (ArrayList)Session["selectedRows"];
}
}
Get selected rows when Page Index Changed
protected void GetSelectedRows()
{
SessionToArrayList();
foreach (GridDataItem item in RadGrid1.Items)
{
string CustomerID = item["CustomerID"].Text;
if (item.Selected)
{
if (!arrayList.Contains(CustomerID))
{
arrayList.Add(CustomerID);
}
}
else
{
if (arrayList.Contains(CustomerID))
{
arrayList.Remove(CustomerID);
}
}
}
Session["selectedRows"] = arrayList;
}
Reselected rows when Page Index Changed
protected void ReSelectedRows()
{
foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
{
string CustomerID = item["CustomerID"].Text;
if (arrayList.Contains(CustomerID))
{
item.Selected = true;
}
}
}
