Sorting groups by week number

Want to sort my group by week number based on the date field.
Trying to convert my old grid (attached old_grid.gif) to Telerik: RadGrid (attached telrik_grid.gif) but the grouping gets sorted recipe from 1-52. I want to get the grouping based on the date field, in this case, week 8 (see attached old_grid.gif)

Attached old_grid.gif is correct grouped........

The asp:SqlDataSource:

SelectCommand="select * from dogtraining where fidnr = @fidnr Order By datum DESC"

The GroupByExpressions:

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldName="weeknumber" FieldAlias="Vecka" />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="weeknumber" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

Rebind and Update in multiple nested itemtemplate

Hi,

I am trying to figure out how to rebind and update only:
RadListView, which exists in a RadGrid nestedviewtemplate, which is again in another RadGrid's nestedviewtemplate

Steps:

I am calling a RadWindow when user clicks on a button, which exists in RadListView itemtemplate
After adding a record, radwindow should close and rebind and update only that RadListView, which called the RadWindow.

Simple example format with out columns and datasources:

<telerik:RadGrid ID="RadGrid1" runat="server">
<MasterTableView>
<NestedViewTemplate>
<telerik:RadGrid ID="RadGrid2" runat="server">
<MasterTableView>
<NestedViewTemplate>
<telerik:RadListView ID="RadListView1" runat="server">
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text="Button" />
</ItemTemplate>
</telerik:RadListView>
</NestedViewTemplate>
</MasterTableView>
</telerik:RadGrid>
</NestedViewTemplate>
</MasterTableView>
</telerik:RadGrid>

I will be really thankful if anyone can help.

[Solved] Able to select disabled items

Hi,

Normally you can't select a listboxitem that is set Enabled="false". But when selectmode="Multiple" and using shift keybord key, you can still select a disabled item.:

<telerik:RadListBox ID="rlb" runat="server" SelectionMode="Multiple">

<Items>

<telerik:RadListBoxItem Text="aaa" />

<telerik:RadListBoxItem Text="bbb" Enabled="false" />

<telerik:RadListBoxItem Text="ccc" />

</Items>

</telerik:RadListBox>

To select item "bbb":
Select the first item. Hold down shift key. Select the last item.
"bbb" gets selected. This should not be possible, right?

Caesar

if (e.Node.ID == "Parent")
{
for (int i = e.Node.GroupItems[0].RenderedFields.Count - 1; i >= 0; i--)
{
e.Node.GroupItems[0].RenderedFields[i] = new OrgChartRenderedField();
}
}

Thanks
