I have a nested Gridview that displays accounts based on the parent gridview record.  Switching to Edit mode for the rows in the nested seems to work, but the Update function only works for the first row. If you select any row other than the first, the .EditIndex and SelectedIndex = -1
Protected Sub grdProducersList_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles grdProducersList.RowUpdating
        Dim iRow As Integer = e.RowIndex
        Dim grdAccounts As GridView = CType(grdProducersList.Rows(iRow).FindControl("grdAccounts"), GridView)
        'Dim iRow2 As Integer = grdAccounts.EditIndex
        'Dim ddlsecurity As DropDownList = CType(grdAccounts.Rows(iRow2).FindControl("ddlsecurity"), DropDownList)
        Dim srcAccounts As SqlDataSource = CType(grdProducersList.Rows(iRow).FindControl("srcAccounts"), SqlDataSource)
        Dim grdRow As GridViewRow = grdAccounts.Rows(grdAccounts.EditIndex)
        Dim ddlsecurity As DropDownList = CType(grdRow.FindControl("ddlSecurity"), DropDownList)
        'For Each row As GridViewRow In grdAccounts.Rows
        'Dim ddlsecurity As DropDownList = CType(row.FindControl("ddlSecurity"), DropDownList)
        srcAccounts.UpdateParameters("Security").DefaultValue = ddlsecurity.SelectedValue.ToString
        'Next
        ' Dim ddlSecurity As DropDownList = CType(grdAccounts.SelectedRow.FindControl("ddlSecurity"), DropDownList)
 
 
    End Sub
 
Protected Sub grdProducersLIst_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdProducersList.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim CompanyID As String = CType(DataBinder.Eval(e.Row.DataItem, "CompanyID"), String)
            Dim CoopID As String = CType(DataBinder.Eval(e.Row.DataItem, "CoopID"), String)
            'Dim srcAccounts As SqlDataSource = CType(e.Row.FindControl("srcAccounts"), SqlDataSource)
            Dim srcAccounts As SqlDataSource = CType(e.Row.FindControl("srcAccounts"), SqlDataSource)
            srcAccounts.SelectParameters("CoopID").DefaultValue = CoopID.ToString
            srcAccounts.SelectParameters("CompanyID").DefaultValue = CompanyID.ToString
 
        End If
    End Sub

Thanks, for the reply. I'm using e.RowIndex to get the row of grdProducersList, but I'm having trouble either understanding the whole nesting thing, and/or getting the row in grdAccounts that is being selected and updated.

From what I can see, you suggestion to use e.RowIndex works. Since grdAccounts is nested in grdProducersList, how do I determine which row in grdproducerslist the nested gridview is in so I can grab it and the sqldatasource?

I think this is close, but how do I determine what the current row is in grdProducersList?
Dim grdAccounts As GridView = CType(grdProducersList.Rows(0).FindControl("grdAccounts"), GridView)

I believe I figured it out. By using the sender of the  Protected Sub grdProducersList_RowUpdating procedure, I'm able to determie the GridView that fired the event. From this I'm able grab its datasource with   Dim srcAccounts As SqlDataSource = CType(grdAccounts.DataSourceObject, SqlDataSource) and populate the parameter from the dropdownlist.
