Questions on UI for ASP.NET AJAX Forum

For some reason any error that occurs within a request initiated by AJAX Manager, even if it's handled within a try..catch block is generating a javascript PageRequestManagerServerErrorException error and the try...catch code is not being executed. This *only* happens after the site has been deployed to our web server. It does not happen when running locally on our machines. I've tried setting CustomErrors in the web.config to On and Off with no change. Any ideas?

Exact error:

Message: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
Line: 6
Char: 84093
Code: 0

and/or

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

Same issue as here: http://forums.asp.net/t/1044963.aspx?PageIndex=3

Defect in List View control

Hi,

I've found an issue with the Listview control. I have within my application 2 list views on one page, within different user controls. If something is updated in one, it needs to reload the other, I have to do this using client side java script. I can get them to look like they are refreshing, it fired all the correct events etc, debugging shows that the control has the new values within it, however the web page doesn't update to show the new item(s). I've created a full test project to demonstraight this. I use __doPostBack on a control which is within the RadAjaxManagerProxy to update the control, but it doesn't update. If you turn Ajax off it works as expected.

I need to upload the test solution or email it to you, can you let me know how to do this please?

Cheers,

Davoc

Excel output on Mac - cells moving upis

Hi

Clients have reported a strange problem with Excel output from a grid; can anyone help?
It is serious because it is not obvious to the user that it has happened, so they see erroneous data, rather than an error message...

If a line of output in excel has an empty cell, then the content of the cell immediately below it moves up
to fill the space, as if all the columns are independent. The context is that the file is downloaded, then opened
on mac using Excel in Office for Mac 2011.

I could try writing a space character instead of of a null value but I am not sure that is the right answer.

The output is fine on PC, and also fine in the pdf version opened on Mac

Help!

Thanks

Clive

PS:
Mac OS: 10.6.5
Website server: windows server 2003, iis6, asp.net 4.0, RadAjax version is Q2 2009

Need access to Parent Cells in Grid Hierarchy: *.aspx

I am using the following code to select the parent row. I need to do this when the item is expanded but it's working only on collapse How do I make work on expand.
Private Sub RadGrid1_ItemCommand([source] As Object, e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid1.ItemCommand
   If e.CommandName = RadGrid.ExpandCollapseCommandName Then
      Dim item As GridItem
      For Each item In e.Item.OwnerTableView.Items
          If item.Expanded Then
            item.Selected = True
          End If
      Next item
   End If
End Sub 'RadGrid1_ItemCommand

Alternately, does or can Telerik provide an option to do this. When a Parent row in a Grid Hierchy is expanded automacally select the row if row selection is tuened on (multiple or single)

Scriptmanager ScriptReference error in Sharepoint

hello,

I have been trying to include the telerik jquery libraries.
I realize by running on sharepoint I have to turn Assembly
references into the full assembly name with version info and
key number. so as a result I have changed my script references as in the code block below.
Keep in mind that this code runs in a master page, and that the page works when
I comment out the the script references. Otherwise I get the error which I posted below this
code block. Perhaps I am writing the reference incorrectly? Thanks for any help

Export Question (Ignore Paging)

I have a screen that allows the exporting of grid. When the page first loads, I do not bind the grid to save loading time (there is a bunch of search criteria at the top). Now, I have an export and search button the user can click, but if they click export before the data is bound, I get an error stating the datssource needs to be set first.

What am I missing here?

[Solved] Specified argument was out of the range of valid values. Parameter name: index

Hi.
I got this error when i tried to edit the row in a hierarchical grid. I have one nested grid where i changed the UnitPrice value in ItemDataBound event. I need do divide the value to get the right currency. (If i do not, than i can do edit action in the nested grid without getting the error.) I have found in the forum other thread with the same error but it does not solve my case. The code i use is:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

LoadTransAndDetailValues(e);

}

private void LoadTransAndDetailValues(GridItemEventArgs e)

{

var item = e.Item as GridDataItem;

if (e.Item.DataItem is Detail)

{

var detail = e.Item.DataItem as Detail;

double? unitPrice = detail.UnitPrice;

item["UnitPrice"].Text = (unitPrice.HasValue && unitPrice.Value != 0) ? (unitPrice.Value / 100.00).ToString() : "";

}
