[Solved] Find detailsviews in nestedview

[BOS]

How do I loop thru all detailsviews in a nestedview without using the ID's?

<NestedViewTemplate>
                        <asp:Panel ID="Panel1" runat="server"">
                            <telerik:RadTabStrip ID="RadTabStrip1" runat="server"
                                                 MultiPageID="RadMultiPage1"
                                                 SelectedIndex="0">
                                <Tabs>
                                    <telerik:RadTab runat="server" Text="Tab1" PageViewID="RadPageView1">
                                    </telerik:RadTab>
                                    <telerik:RadTab runat="server" Text="Tab2" PageViewID="RadPageView2">
                                    </telerik:RadTab>
                                    <telerik:RadTab runat="server" Text="Tab3" PageViewID="RadPageView3">
                                    </telerik:RadTab>
                                </Tabs>
                            </telerik:RadTabStrip>

                            <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" RenderSelectedPageOnly="false">
                                <telerik:RadPageView ID="RadPageView1" runat="server">

                                                       ConnectionString = ...
                                    </asp:SqlDataSource>

                                    <asp:DetailsView ID="DetailsView1" runat="server"
                                                    Width="1000px" AutoGenerateRows="False"
                                                    DataKeyNames="Key1,Key2" DataSourceID="datasource1">
                                        <FieldHeaderStyle Font-Bold="True" Width="150px"  />
                                        <Fields>
                                            <asp:BoundField DataField="datafield1" HeaderText="Header1:" ReadOnly="True"
                                                SortExpression="key1" />
                                            <asp:BoundField ...  />
                                        </Fields>
                                    </asp:DetailsView>
                                </telerik:RadPageView>

                                <telerik:RadPageView ID="RadPageView2" runat="server">
                                    <asp:DetailsView ID="DetailsView2" ....

I've tried this, but it doesn't work:

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

foreach (GridNestedViewItem nestViewItems in RadGrid1.MasterTableView.GetItems(GridItemType.NestedView))

{

foreach (Control ctrls in nestViewItems.Controls)

{

if (ctrls is DetailsView)

{

DetailsView dv = (DetailsView)ctrls;

do something ...

}

}

}     }

Hi,

To see more information on the required functionality, please refer to the following topic:

http://www.telerik.com/help/aspnet-ajax/grdtraversingdetailtablesitemsingrid.html

However, please keep in mind that in order for the detail tables to be accessible in such a manner, you would need to set the HierarchyLoadMode to client, so that the inner level is loaded as well.
I hope this information helps.

Sorry, but I'm still lost :-)

I need at solution resembling this:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    foreach (GridNestedViewItem nestViewItems in RadGrid1.MasterTableView.GetItems(GridItemType.NestedView))
    {
        foreach (... DetailsView dtvItems ....)
        {
            setCssDetailViews(dtvItems);
        }
    }
}

For now I use this solution:

foreach (GridNestedViewItem nestViewItems in RadGrid1.MasterTableView.GetItems(GridItemType.NestedView))
{
    DetailsView dv;

    dv = (DetailsView)nestViewItems.FindControl("DetailsView1");
    setCssDetailViews(dv);

    dv = (DetailsView)nestViewItems.FindControl("DetailsView2");
    setCssDetailViews(dv);

    ....
    ..
}

It works, but I need a more dynamic solution, in which I doesn't have to address the detailsviews by the IDs.

Hi BOS,

Try the following too:

protected void Page_PreRender(object sender, EventArgs e)
{
    foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
    {
        if (item.HasChildItems)
        {
            foreach (GridTableView innerView in item.ChildItem.NestedTableViews)
            {
                //innerView is the nested GridTableView for GridDataItem item
            }
        }
    }
}
