In the following I'm selecting the third page and saving the state for user1 and then selecting the fifth page and saving the state for user 2. Now if I load the user1 settings the page is not showing as 3 but the same 5 which was saved for user2.

Is there any work around for this?

Unable to Filter on CHAR column

I have a RadGrid bound to a collection, the collection has integer, strings and char datatypes. I can group by all these nor problem and I can filter with the integer and strings however using the CHAR and equalto does not work.

I have one column that contains either a V or an O (for Vacant or Occupied) when I attempt to filter by V and EqualTo I still get both V and O items, I tried using O and greater then to just get the V no luck still get them all. However I can drag the column to the group by bar and it groups the items correctly.

(I have set the datatype for the column to System.Char)

30 megabyte limit?

Hi. I have a client that I've developed a solution for using RadUpload. We've discovered just recently that there seems to be a barrier somewhere around 30 megabytes. I flipped over to another solution I have that uses RadUpload (different server) and am experiencing the same thing. Both servers are Server 2008, and I've modified the web.config file on both servers as follows:

<httpRuntime useFullyQualifiedRedirectUrl="true" maxRequestLength=102400"



requestLengthDiskThreshold

="8192" executionTimeout="3600"/>

So both servers are configured for a maximum 100MB file and 60 minutes of upload.

I have tested files of various size between 1MB and 28MB and they upload fine - everything, including my ProgressArea, works. When i upload a file above 30 MB, though, my ProgressArea doesn't display, and after about 2 minutes (regardless of connection speed), I get redirected to a 404 or timeout page.

I've tested this on everything from a 512kb (up) connection to a 7mb (up) connection and the barrier seems to be right around 30 megabytes, consistently.

I am running these inside UpdatePanels using AJAX but have added a PostBackTrigger to my upload button to trigger a full page postback when it is clicked.

Hopefully that's enough info to get some help here. I've seen several people with issues related to the web.config settings and the ajax postback settings, but I think I have both of those dealt with. I'd appreciate your assistance.

Thanks,

Chet

How do I generate this chart?

Hi,
I get via LINQ this data structur from a SQL Server:

Count Product Date

1	Product1	03.11.2009
2	Product1	04.11.2009
1	Product2	04.11.2009
3	Product1	05.11.2009
1	Product2	05.11.2009
1	Product3	05.11.2009
3	Product1	06.11.2009

As you can see I want to group my products by the the same date to visualize how many different products are counted on this day.
I want this to show as a line chart.
I attached a file with a image of what i mean.

How can I do this programmatically?

Problems with Scheduller

Hello,

I have a problem with the scheduller. When I click on any option of the tool it refreshes the entire web page, not just the scheduller.

Should I change any property?

Thanks.

ScriptResource.axd error when navigating away from page

I have a couple of pages on my site that dynamically add RadPanelItems to a RadPanelBar and apply header and content templates to them. I have recently noticed that when I navigate away from these pages when the site is debugging, I get a ScriptResource.asxd?d=LotsOfNumbersAnNdLetters..... error that reads like so...

Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.

I can only assume this has something to do with the Templates that get applied, but cant work out whats wrong as the pages work exactly as they're meant to and don't produce any server or client side errors until this one. Again, this error ONLY occurs when navigating away from the page, not on postback.

The templates do have event handlers added to controls that are built in the templates and think it might have something to do with these, but when I comment these handlers and methods out, I still get the same error...

It's very puzzling and I have to get it fixed but have run out of ideas.

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Hi guys,

I am trying to upgrade my existing web project where I'm using the RadControls's 2007 Q2 RadAjaxManager to "Prometheus"'s RadAjaxManager.

I have followed instructions in documentation (Adding RadControls 'Prometheus' to an existing application), but I still receive this error when I open a page with "Prometheus" RadAjaxManager:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

What could be wrong?

Regards,
Alex

Hide Collapse image when no records using an object to populate detail table

I tried the http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html way of hiding the expand/collapse image but with no success. I don't use the HierarchyLoadMode = ServerBind way of populating the details table - but I don't have a problem populating the details table.

Here is the code for the detail table bind and my attempt to hide the collapse/expand column for parent rows with no detail items:

Private Sub RadGridEvents_DetailTableDataBind(ByVal source As Object, ByVal e As GridDetailTableDataBindEventArgs) Handles RadGridEvents.DetailTableDataBind

Dim dataItem As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)

Select Case e.DetailTableView.Name

Case "EventMerchantList"

Dim EventID As Integer = dataItem.GetDataKeyValue("eventID")

Dim eventML As List(Of Merchant)

eventML = Merchant.GetAllMerchantsByEventID(EventID)

If Not eventML Is Nothing Then

If eventML.Count > 0 Then

e.DetailTableView.DataSource = eventML

End If

End Select

End Sub

Protected Sub RadGridEvents_PreRender(ByVal sender As Object, ByVal e As EventArgs)

HideExpandColumnRecursive(RadGridEvents.MasterTableView)

End Sub

Public Sub HideExpandColumnRecursive(ByVal tableView As GridTableView)

Dim nestedViewItems As GridItem() = tableView.GetItems(GridItemType.NestedView)

For Each nestedViewItem As GridNestedViewItem In nestedViewItems

For Each nestedView As GridTableView In nestedViewItem.NestedTableViews

If nestedView.Items.Count = 0 Then

Dim cell As TableCell = nestedView.ParentItem("ExpandColumn")

cell.Controls(0).Visible = False

nestedViewItem.Visible = False

End If

If nestedView.HasDetailTables Then

HideExpandColumnRecursive(nestedView)

End If

Next

End Sub

It seems like this should be an easy thing to do but I cannot find the answer. Thanks in advance for any help I get with this.
