Complete Hierarchy always in Editmode Bound Server Site

Hi,

i got a Telerik Grid and need all items InPlace EditAble.
It works fine if i just open up a few Levels, but on some deeper Levels i get errors while collapsing/expanding the hierarchy.
The complete hierarchy could not be expanded at startup. (To much data)

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

The Data is bound on serverside.

Could please somebody give me an hint. I tryied a lot of the stuff explained in examples and forum entries.
But didn't get it run without having errors. :-(

Databinding:

protected void RadGridHierarchy_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

if (!e.IsFromDetailTable)

{

RadGridHierarchy.DataSource = GetMaterialHierarchyDataTableFiltered("ROOT", false);

}

protected void RadGridHierarchy_DetailTableDataBind(object sender, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

string ParentCode = dataItem.GetDataKeyValue("MaterialHierarchyNodeCode").ToString();

e.DetailTableView.DataSource = GetMaterialHierarchyDataTableFiltered(ParentCode, false);

}

Set items to editmode:

protected void RadGridHierarchy_PreRender(object sender, EventArgs e)

{

SaveGridValues();

if (_expandedItem != null && _expandedItem.Expanded)

{

if (_expandedItem.HasChildItems)

{

foreach (GridTableView view in _expandedItem.ChildItem.NestedTableViews)

{

foreach (GridDataItem item in view.Items)

{

item.Edit = true;

}

view.Rebind();

}

for (int i = 0; i < RadGridHierarchy.MasterTableView.Items.Count; i++)

{

RadGridHierarchy.EditIndexes.Add(i);

}

RadGridHierarchy.Rebind();

}

protected void RadGridHierarchy_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.ExpandCollapseCommandName)

{

_expandedItem = (GridDataItem)e.Item;

}

Thanks a lot for your help.
I really don't know what to try anymore...

Kind regards

Lars

RadGrid NestedView expand event

Hi, I would like to be able to assign custom content to the NestedView (a literal control inside the nestedview) - only when the arrow is clicked and the view gets expanded.

At that point, I would find a literal control and add content dynamically. I do not want to assign the literal on ItemDataBound as that would find and populate all the literal controls - this is not desirable as they are going out and building feeds from external services and the performance would be terrible.

So what I am looking for is an event to work from, but the ItemCommand would not work, because the literalControl is not yet created/cannot be found in the page life cycle. Any creative thoughts welcome.

Return All Data From Grid

<telerik:RadGrid ID="RadGridItemSizes" runat="server" AllowPaging="false" AllowSorting="True" GridLines="None" Skin="Windows7" Width="95%">

<MasterTableView AutoGenerateColumns="false" EditMode="InPlace" >

<NoRecordsTemplate>

No Sizes Found

</NoRecordsTemplate

<Columns>

<telerik:GridBoundColumn DataField="IT_SizePk" UniqueName="SizePk" Visible="false" />

<telerik:GridCheckBoxColumn DataField="Checked" HeaderText="Select" HeaderStyle-Width="20px" UniqueName="Checked"/>

<telerik:GridBoundColumn DataField="Size" HeaderText="Size" HeaderStyle-Width="40px" ReadOnly="true"

<telerik:GridNumericColumn DataField="SizePremium" HeaderText="Size Premium" HeaderStyle-Width="100px" UniqueName="SizePremium" DecimalDigits="2" DataFormatString="{0:f3}" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

I have the above Grid. And the following Code being used for this grid

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Try

'Put In Edit Mode

Dim i As Integer

For i = 0 To RadGridItemSizes.PageSize - 1

RadGridItemSizes.EditIndexes.Add(i)

Next i

Catch exc As Exception 'Module failed to load

ProcessModuleLoadException(Me, exc)

End Try

End Sub

Private Sub SaveDataSpecificationTab()

Dim Sizes() As Guid = {}

Dim SizesPrices() As Double = {}

For Each DataItem As GridEditableItem In RadGridItemSizes.EditItems

Dim CheckBox As CheckBox = DirectCast(DataItem("Checked").Controls(0), CheckBox)

Dim txtbox As TextBox = DirectCast(DataItem("SizePk").Controls(0), TextBox)

Dim SizePk As String = txtbox.Text

txtbox = DirectCast(DataItem("SizePk").Controls(0), TextBox)

Dim SizePremium As String = txtbox.Text

If CheckBox.Checked Then

ReDim Preserve Sizes(Sizes.Length)

ReDim Preserve SizesPrices(SizesPrices.Length)

Sizes(UBound(Sizes)) = New Guid(SizePk)

SizesPrices(UBound(SizesPrices)) = SizePremium

End If

Next

End Sub

Private Sub RadGridItemSizes_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGridItemSizes.ItemCreated

If (Not Page.IsPostBack AndAlso TypeOf e.Item Is GridEditableItem) Then

e.Item.Edit = True

End If

End Sub

Private Sub RadGridItemSizes_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGridItemSizes.NeedDataSource

Dim Item As ConvergenceDataAccess.Items = New ConvergenceDataAccess.Items(Me.ConnectString)

RadGridItemSizes.DataSource = Item.GetDataTable_ItemSizesPremium(New Guid(ItemPk.Value))

End Sub

This page is also using the RadAjaxManager.

I haven't been able to pull the data from the grid to save using the SaveDataSpecificationTab() Sub - being called by a button.

I've tried pretty much all of the suggestions I have found here and through google.
