How to fetch value of hidden filed from selected row in gridview.
Scenario:
I have a grid view.. the grid view contains hidden field.
I want when a particular row of the gridview is selected then the value of the hidden field should be retained in viewstate and then when Update button is clicked i want to pass this value as a query string . How to do this. Will using viewstate be good in this case???

0	Hi, In the buttons command argument you can pass the value & on rowcommand event you can catch that button. I thing there no need of any viewstate from my side. I hope, this will help you. Thanks & Regards, Shailesh Sp, if this helps please login to Mark As Answer. \| Alert Moderator

0	Don't use the selectedindexchange. rotected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e) { if (e.CommandName == "RowClick") // set EnablePostBackOnRowClick property of RadGrid ClientSettings as 'True' to fire this { HiddenField1.Value = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["OrderID"].ToString(); //save the selected row index in a HiddenField Session["OrderID"] = HiddenField1.Value; } } Sp, if this helps please login to Mark As Answer. \| Alert Moderator

Don't use the selectedindexchange.
rotected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

if (e.CommandName == "RowClick") // set EnablePostBackOnRowClick property of RadGrid ClientSettings as 'True' to fire this
{

HiddenField1.Value = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["OrderID"].ToString();
//save the selected row index in a HiddenField
Session["OrderID"] = HiddenField1.Value;
