Javascript not firing after Ajax callback

I have a quite complex nested controls scenario so I wasn't sure to post here on in the RadGrid section anyway..
The control chain is this:
RadGrid (HierarchyLoadMode = "Conditional") > NestedViewTemplate > Panel > RadMultipage (RenderSelectedPageOnly = "false") > UserControl > FormView

Inside the FormView I have some RadScriptBlock that provide functions or some page load initialization.
Just to make an example (that I'm trying to use for debugging as well) let's say inside the ItemTemplate of the FormView I have

<telerik:RadScriptBlock runat="server">

<script type="text/javascript">

alert('test');

</script>

</telerik:RadScriptBlock>

While inside the EditItemTemplate of the FormView I don't have this script.
I expand the RadGrid nested view of a row and initialize the FormView inside my User Control to FormViewMode = Edit.

So the script inside ItemTemplate it's not fired and that's correct.

Then upon postback (ajax since the RadGrid is Ajaxified with RadAjaxManager) I switch the FormView inside my User Control to FormViewMode = ReadOnly and the problem is that the javascript alert it's not called the same and this is not good.

Same thing of course apply if I expand the RadGrid NestedViewTemplate with FormView inside in FormViewMode = ReadOnly (script works) then after ajax postback I switch to FormViewMode = Edit (no script there it's ok) then after another ajax postback switch back to FormViewMode = ReadOnly (script doesn't work anymore)

I don't know where in the chain is the culprit if in Multipage rendering behaviour or in RadGrid or in ajax or it's not even tied to Telerik controls (in this case forgive me for the question and you can delete the topic).

Any hint? This is driving me crazy.. :)

Grouping by month/year

I have a Radgrid with a column "Period " which is shown as month/year (MMM/yyyy).
The column is bound to an sql table and the field is a datetime.

I have multiple entries for each period and I would like to group the rows by such filed in order to have all months/years collapsable and separated in the grid. How can I achieve that?
I have looked at various examples but I am not coming right. Your support is appreciated.
Thank you,
Felice

[Solved] Replace text in excel footer when exporting

Hi.

I am trying to replace specific characters when exporting to excel as it doesn't recognise the contents as numeric data when I do not. I have managed to get it working for the normal cells but it I cannot seem to get it working for the footers.

Please find my code snippet below, and advise on any possible ways to do this.

Protected Sub grdSingleCurrency_ExportCellFormatting(sender As Object, e As ExportCellFormattingEventArgs) Handles grdSingleCurrency.ExportCellFormatting, grdHoldingsSummary.ExportCellFormatting,

grdMultiCash.ExportCellFormatting, grdMultiCurrency.ExportCellFormatting, grdSingleCash.ExportCellFormatting

If (Not String.IsNullOrWhiteSpace(e.Cell.Text)) Then

e.Cell.Text = e.Cell.Text.Replace(",", String.Empty).Replace(" ", String.Empty)

End If

If (Not String.IsNullOrWhiteSpace(e.FormattedColumn.FooterText)) Then

e.FormattedColumn.FooterText.Replace(",", String.Empty)

End If

End Sub

On to the second issue, how/where can I do the same as the above, but for csv export? As there isn't a csvExportFormatting event.

Any and all help will be greatly appreciated.

Kind regards.
