nested grid problem

[MaruBindiya]

i m using nested grid and in child grid i m using EmptyDataTemplate in which i hv one htmlanchor tag which is redirecting to another page when that child grid is empty and i m passing parentgridrow id as query string parameter to that anchor tag. here i m giving u code what i m using. Protected Sub ParentGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles ParentGrid.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim s As SqlDataSource = CType(e.Row.FindControl("SqlDataSource1"), SqlDataSource) s.SelectParameters(0).DefaultValue = e.Row.Cells(0).Text CType(e.Row.FindControl("ChildGrid"), GridView).DataBind() End If End Sub Protected Sub grdProduct_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Dim grd As GridView = CType(sender, GridView) Dim grdr As New GridViewRow(-1, -1, DataControlRowType.EmptyDataRow , DataControlRowState.Normal) Dim cell As New TableCell cell.ColumnSpan = 2 cell.Width = Unit.Percentage(100) Response.Write(CType(sender, GridView).Rows.Count) End Sub it is giving output like shown below: 0 7 0 2 0 15 where 7 indicates 7 row of 1st child grid (child grid in 1st row of parent grid) same way 2 and 15 also means in my parent grid there r only 3 row (means there r only 3 child grid would created) then why i m geting other three zeros. can any one explain me the execution flow for nested grid. Thanx in advance,

This Event is firing twice. That is before DataBinding (Empty Grid), and after DataBinding (With Data).
