RadGrid in RadGrid in FormView

[Miranda]

Hi Folks, first time on this forum so please be gentle.

I have an asp.net Formview with a RadGrid (rgTradeName) inside it.

rgTradeName has two RadGrids nested inside the edit form template (rgAPSummaryEdit & rgAPSummaryEditNew). 

rgAPSummaryEditNew has a grid button column and is fires rgAPSummaryEditNew_ItemCommand when the user clicks on the button.

What I need to do is add the line from rgAPSummaryEditNew that the user has clicked on to the data that populates rgAPSummaryEdit. The hard part is finding rgAPSummaryEdit in the c# page-behind. So far rgAPSummaryEditNew_ItemCommand looks like this:

    protected void rgAPSummaryEditNew_ItemCommand(object sender, GridCommandEventArgs e)
    {
        RadGrid rgTN = (RadGrid)fvLicenceSummary.FindControl("rgTradeName");
        if (rgTN != null)
        {
            
        }
    }

rgTN is not null when I run this, but I have no idea how to loop through rgTN to find rgAPSummaryEdit. I've tried quite a number of things, none of them worked.

Can anyone please tell me how to find this RadGrid nested in a RadGrid Nested in a FormView?

Thanks in advance.

Hi Miranda,

I guess you want to access the RadGrid inside EditForm during the Edit and bind it. Please check the following code snippet.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server">
    <MasterTableView >
        <EditFormSettings EditFormType="Template">
            <FormTemplate>
                <telerik:RadGrid ID="RadGrid2" runat="server" OnNeedDataSource="RadGrid2_NeedDataSource">
                </telerik:RadGrid>
              </FormTemplate>
        </EditFormSettings>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
  if (e.CommandName == RadGrid.EditCommandName)
  {
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
      GridEditableItem parentItem = e.Item as GridEditableItem;
      RadGrid grid = parentItem.FindControl("RadGrid2") as RadGrid; //Search for the inner RadGrid
      grid.Rebind();
    }
  }
}
protected void RadGrid2_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
 (sender as RadGrid).DataSource = GetDataTable("SELECT * FROM Orders ");// bind the RadGrid with data
}

Thanks,

Hi Shinu, thank you for the reply. The aspx that I have is this:
    <asp:FormView ID="fvLicenceSummary" runat="server" DataSourceID="sdsLicenceSummary" DefaultMode="ReadOnly" OnDataBound="fvLicenceSummary_DataBound" OnItemCommand="fvLicenceSummary_ItemCommand" 
            OnItemUpdating="fvLicenceSummary_ItemUpdating">
        <EditItemTemplate>
            <rad:RadGrid ID="rgTradeName" runat="server">
               <MasterTableView Width="880" CommandItemDisplay="Top" DataSourceID="sdsTradeNames" DataKeyNames="BrandCode">
                  <EditFormSettings EditFormType="Template">
                      <FormTemplate>
                         <rad:RadGrid ID="rgAPSummaryEdit" runat="server" AutoGenerateColumns="false" OnItemDataBound="rgAPSummaryEdit_ItemDataBound">
                             <MasterTableView>
                                <Columns>
                                   <rad:GridBoundColumn HeaderText="Licence Number" DataField="LicenceNumber" />
                                   <rad:GridBoundColumn HeaderText="EV Code" DataField="EVCode" />
                                   <rad:GridButtonColumn ItemStyle-HorizontalAlign="Right" ImageUrl="/images/form_icons/delete.png"
                                       ButtonType="ImageButton" CommandName="Remove" Text="Remove" UniqueName="AlterColumn">
                                   </rad:GridButtonColumn>
                                </Columns>
                              </MasterTableView>
                           </rad:RadGrid>
                           <rad:RadGrid ID="rgAPSummaryEditNew" runat="server" AutoGenerateColumns="false" OnItemCommand="rgAPSummaryEditNew_ItemCommand">
                              <MasterTableView>
                                <Columns>
                                   <rad:GridBoundColumn HeaderText="MA Number" DataField="Description" />
                                   <rad:GridBoundColumn HeaderText="EV Code" DataField="EVCode" />
                                   <rad:GridBoundColumn DataField="LicenceAuthorisedProductCode" Visible="false" />
                                   <rad:GridBoundColumn DataField="LicenceMANumberCode" Visible="false" />
                                   <rad:GridButtonColumn ItemStyle-HorizontalAlign="Right" ImageUrl="/images/grid_icons/AddRecord.gif"
                                      ButtonType="ImageButton" CommandName="Add" Text="Add" UniqueName="AlterColumn">
                                   </rad:GridButtonColumn>
                                </Columns>
                               </MasterTableView>
                              </rad:RadGrid>

And the C# is this:

    protected void rgAPSummaryEditNew_ItemCommand(object sender, GridCommandEventArgs e)
    {
        RadGrid rgTradeName = (RadGrid)fvLicenceSummary.FindControl("rgTradeName");
        if (rgTradeName != null)
        {
            //How do I find rgAPSummaryEdit from here?
        }
    }

So the item command event belongs to the second nested RadGrid (rgAPSummaryEditNew)  that is nested within rgTradeName.and the first line succesfully finds the first nested Radgrid and what I need to know is how to loop through the rgTradeName object in order to find the RadGrid nested within it please?

Put another way, within the item command event I need to have an object which is rgAPSummaryEdit.

Thank you.

Hi Miranda,

If you want to access the grid inside EditForm when the main Grid is in editmode, try the following code snippet.

C#:

protected void rgAPSummaryEditNew_ItemCommand(object sender, GridCommandEventArgs e)
{
    RadGrid rgTradeName = (RadGrid)fvLicenceSummary.FindControl("rgTradeName");
    if (rgTradeName != null)
    {
        foreach (GridDataItem item in rgTradeName.EditItems)
        {
          GridEditableItem edititem = (GridEditableItem)item.EditFormItem;
          //Access the grid inside editform
          RadGrid rgAPSummaryEdit = (RadGrid)edititem.FindControl("rgAPSummaryEdit");
        }
    }
}

Thanks,
Shinu
