I am having problem in maintaining state of gridview when performing
search. My Code goes like this:
protected void Page_Init(object sender, EventArgs e)
{
if (!IsPostBack)
{
GridView1.DataSource = DataSource;
GridView1.DataBind();
}
}
protected void Page_Load(object sender, EventArgs e)
{
string strSql = "Select * from EMPLOYEE" ;
strSql = strSql + "Where " + " E_NAME = TEST"; // depends
on search criteria. For now i have simple SQL statement
DataTable dt =DataSource.GetData();
DataRow[] dr = dt.Select(strSql);
GridView1.DataSource = dr;
GridView1.DataBind();
}
protected void GridView1_SelectedIndexChanging(object sender,
GridViewSelectEventArgs e)
{
usercontrol.BuildEmployeRecord(userID, Info);
}
Each row in gridview have toggle button to expand and collapse, when
clicked, it will call user control to display information related with
that particular record.
The problem is when i click any linkbutton inside user control it will
collapse the row without performing any task it is supposed to do.
I guess the problem is in GridView. When no search is performed
everything works fine. Only when search is performed I am getting this
problem. When Search is performed it re binds the gridview and view
state iformation is changed. Since view state information is changed
the user control won't be able to get same information for any action
to perform.
I'd really appreciate if you can provide me with suitable example to
solve this problem or any glimpse on how to maintain view state even
after gridview is rebind.
Thank you.
