passing client side variable value to server side

 i have a grid and  by click on the rows, the onrowclick event is fired on client side. I want to pass the row index to the server side. 
As there are not sessions variables in javascript so i am stuck to pass the row to the server side.. I have made a texbox and set its value
to the index in the onrowclick event but when refresh calls, the text box became empty as the value set is on client side, i want page to persist
the value,  How can i do that? Tel me some way passing the row index to the server side??

Hi,
You can call GridView_SelectedIndexChanging event on row click event so that you can get the index of the row that is selected
To achieve this you have to add attribute "onclick" to row in GridView_RowDataBound event as
e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.GridView, "Select$" + e.Row.RowIndex);

And in GridView_SelectedIndexChanging you can do whatever you want since you are getting the row index
Thanks & Regards,
