Hi,

I've implemented a nested view template very similar to the example Nested View Template however I am implementing Edit and Insert of items into grids that reside in the template.  On updates I'll be fine but on inserts, what I need is the datakey of the expanded row of the grid in the MasterTable.

Please see aspx below.  When the user issues an Insert from the UserControl of grdEndorsements (AddEditEndorsement.ascx), what I need in order to complete the insert is the DataKeyNames="EntityID" from the expanded row of grdEntities.  So the logic here is, the user expands the nested view under a given row in grdEntities, they see the grdEndorsements in the RadTabStrip/Multipage and they can insert a new item into grdEndorsements.

I know I can get the datakey name for grdEntities when it expands but I want to get it when the user actually inserts.  It is possible that the user may expand more than one row in grdEntities and then go and insert into a row previously expanded.  I've thought of a few possible solutions but open to suggestions.

What I've left out for brevity is the SQL data source of grdEndorsements.  However, I bring it up since the Label ID="LabelEntityID" is the value I need to complete the insert, I use it as the parameter for the Data Source that feeds grdEndorsements and it works just fine.  I'm just not sure how to get that value on insert.

Thanks.

Hi,

I am looking for the opposite.

Radgrid =ONHANDS

Within ONHANDS - NestedViewTemplate with ONHANDS_NESTED. No asp:panel.

Within ONHANDS_ItemCommand, I want to access dataKeyvalues ofONHANDS_NESTED.

 If e.CommandName = "HOTSHEET" Then
            e.Item.Selected = True
            Dim item As GridDataItem = Nothing
            Dim strPlant As String = rgOnHands.MasterTableView.DataKeyValues(e.Item.ItemIndex)("PLANT")
            Dim strSid As String
            Dim innerGrid As RadGrid = TryCast((TryCast(e.Item, GridDataItem)).ChildItem.FindControl("rgOnHands_Nested"), RadGrid)
            'Dim innerGrid As RadGrid = TryCast(item.ChildItem.FindControl("rgOnHands_Nested"), RadGrid)
            'Dim innerGrid As RadGrid = (TryCast((TryCast(rgOnHands.MasterTableView.Items(0).ChildItem, GridNestedViewItem)).FindControl("rgOnHands_Nested"), RadGrid))

            For Each dataItem As GridDataItem In innerGrid.Items
                strSid = dataItem.GetDataKeyValue("SID")
            Next
            'If TypeOf e.Item Is GridNestedViewItem Then
            '    For Each Item As GridDataItem In innerGrid.Items
            '        Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
            '        strSid = dataItem.GetDataKeyValue("SID")
            '    Next
            'End If

            MsgBox(strSid)


        End If

Hello Kiran,

You can use the following approach to achieve this requirement:

    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == "HOTSHEET")
        {
            GridDataItem item = e.Item as GridDataItem;
            // access the inner grid
            RadGrid innerGrid = item.ChildItem.FindControl("rgOnHands_Nested") as RadGrid;

            foreach (GridDataItem innerItem in innerGrid.Items)
            {
                innerItem.BackColor = System.Drawing.Color.Lime;
            }
        }
    }

Hi Eyup,

That does not seem to work in my case. Does not even go into the For each loop.

        If e.CommandName = "HOTSHEET" Then

            CheckSession()
            e.Item.Selected = True

            Dim item As GridDataItem = TryCast(e.Item, GridDataItem)
            Dim innerGrid As RadGrid = TryCast(item.ChildItem.FindControl("rgOnHands_Nested"), RadGrid)
            Dim strsid As String
            For Each innerItem As GridDataItem In innerGrid.Items
                strsid = innerItem.GetDataKeyValue("SID")
            Next

end if

Hello Kiran,

When binding the nested grid programmatically, add also its DataBinding event handler as demonstrated here:
