Selecting nested RadGrid and accessing child & parent

I have a RadGrid that has another RadGrid nested which also has another nested RadGrid. So there are 3 levels: Level 1 has information about a costumer, level 2 has information about customer´s purchases, and level 3 has info about products that the costumer has bought during the purchase.

Now, I need to be able to select the level 2 row (purchase) and then access the data on all levels to construct a receipt of the purchase. I was able to add the checkbox column to level 2 by adding the GridClientSelectColumn to the column collection and enabling the client side row selection. So visually I have what I need. But my big problem now is:

How do I access the data (contents of the cells) on all levels when I press a "print receipt for selected purchase" -button? I tried accessing it rought the RadGrid1.SelectedItems, but it was null. With just one RadGrid setup I could just use RadGrid1.SelectedItems[0].Cells, but that wont of course work with nested grids.

This might be a noob question, as I am very new to Telerik components. Any recommendations for "RadGrid for dummies" tutorials are welcome.

Thanks in advance!

RadAsyncUpload: Sys.WebForms.PageRequestManagerServerErrorException

Hi,

I am adding the RadAsyncUpload user control both in asp:GridView and page in a single file. After selecting a file and click on Upload I am getting the following error.

---------------------------
Message from webpage
---------------------------
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
---------------------------
OK
---------------------------

The uploaded file is saved into App_Data folder (like nkdeutts.hpj), but OnFileUploaded event is not firing. Before this event is fired I am getting the above error.

If I include the user control only in grid view or only in the page, it is working fine. If I use it in both the places, I am getting the error. Please help me in resolving this error as it is important for me to have the control in both the places.

Thanks.

Designing the Master and Detail

Hello Telerik,

I build the grid columns and set up the relationships in aspx and the data source is set in code-behind. The gird changes depending on a node selection which sends in a ID to filter out the master grid, which in turn filters out the detail grid based off the relationship.

Here is the grid in aspx:

<telerik:RadGrid runat="server" ID="RadGridMemberBoardPosition" Width="350px" Height="460px" AutoGenerateColumns="false" >

<MasterTableView DataKeyNames="MemberId" >

<Columns>

<telerik:GridClientSelectColumn ItemStyle-Width="10%"/>

<telerik:GridBoundColumn DataField="Name" DataType="System.String" HeaderText="Name" UniqueName="Name" />

</Columns>

<DetailTables >

<telerik:GridTableView DataKeyNames="MemberId">

<Columns>

<telerik:GridBoundColumn DataField="FullName" DataType="System.String" HeaderText="FullName" UniqueName="FullName" />

<telerik:GridBoundColumn DataField="EmailAddress" DataType="System.String" HeaderText="EmailAddress" UniqueName="EmailAddress" />

</Columns>

</telerik:GridTableView>

</DetailTables>

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="MemberId" MasterKeyField="MemberId" />

</ParentTableRelation>

</MasterTableView>

<ClientSettings Selecting-AllowRowSelect="true" Scrolling-AllowScroll="true" />

</telerik:RadGrid>

Now in code behind i change the data with the node being selected in a TreeView on the page.

Protected Sub RadTreeViewGroups_NodeClick(sender As Object, e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeViewGroups.NodeClick

If Me.m_cMyManager Is Nothing Then

Me.m_cMyManager = New cMyManager

End If

' get the board positions and the members for those postions - hierarchical grid

Me.RadGridMemberBoardPosition.DataSource = Me.GetGroupBoardPositionDT(Me.m_cMyManager, e.Node.Attributes("GroupId"))

Me.RadGridMemberBoardPosition.Rebind()

End Sub

This code works fine for filling in the master table with the appropriate records. Now when a record is expanded by clicking its arrow - showing the detail grid it is always nothing.

This is the data source for the detail - setup in the page load.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Me.m_cMyManager Is Nothing Then

Me.m_cMyManager = New cMyManager

End If

' get the sql datasource for the detail of the datagrid

Dim mySqlDataSource As New SqlDataSource("System.Data.SqlClient", Me.m_cMyManager.MyDb.ConnectionString(), Me.GetBoardPositionMembersQuery(Me.m_cMyManager))

' add the parameters

Dim myParameter As New UI.WebControls.Parameter("MemberId", DbType.Int64)

mySqlDataSource.SelectParameters.Add(myParameter)

Me.RadGridMemberBoardPosition.MasterTableView.DetailTables(0).DataSource = mySqlDataSource

End Sub

I also tried to put it in the Handles RadGridMemberBoardPosition.DetailTableDataBind event, but it still failed to show the records related to the master table. This is a little different than your example http://demos.telerik.com/aspnet-ajax/grid/examples/programming/hierarchy/defaultvb.aspx so I was wondering if it should all be in the code-behind. Also, if this will work in my scenario with a node changing the data source of a master and detail tables at run-time.

Can you shed some light on this?

Thanks!
SDI
