Weird text appearing problem when using RadGrid inside UpdatePanel

Hi guys,

At the moment I am using a RadGrid inside an UpdatePanel. However on row select of this grid, I always get a weird text on top of the Grid, but inside the Panel which is something like this :

29592|updatePanel|ctl00_cphMain_ctl00_cphMain_dgTestPanel|

Anyone encountered this issue before?

Thanks,
Bernard

Upload form with adUploadProgress on IIS - SharePoint 2010

Hi everyone,
I am trying to implement an upload form (sync/async) on SharePoint 2010 web site hosted on IIS 7. Both asp.net page and web.config are correctly configured and the web part runs with no error (I mean, the page loads, checkbox and select buttons work as expected).
However the uploading process on button click returns with the following message:

RadUpload Ajax callback error. Source url was not found:
Telerik.RadUploadProgressHandler.ashx?RadUrid=63d4f5ee-2777-4728-9467-bb7fbf5ca5e5
Did you register the RadUploadProgressHandler in web.config?

Is there something I miss? Is there some particular issue regarding IIS 7 and SharePoint?
I registered Telerik DLL (Telerik.web.ui) on web configuration file and the asp.net page includes the aforementioned DLLs.

Thanks in advance.
Regards

Giulio

Telerik.Web.UI Disables Microsoft Report Designer

Hi, All:

I have a solution in Visual Studio 2012 (compiled for .NET 4.0) that requires the Telerik RadScheduler and a few other RadControls (AutoCompleteBox, RadTreeView, RadTimePicker, and a few others). Because we have custom event handlers for these components, we must add references within our project to Telerik.Web.UI and Telerik.Web.UI.Skins.

This solution also requires reports created using the Microsoft Report Viewer. If we try to run the Report Wizard to generate the report template, a dialog box titled Microsoft Report Designer displays the message "Object reference not set to an instance of an object". To get around this, we have tried adding an RDLC file and then creating a Dataset that points to a business object that returns the report's collection of data. Unfortunately, this also does not work in that the business objects available within the project do not display in the Dataset drop-down within the Dataset Properties dialog accessed via Report Data for the RDLC file.

When I remove the above two references, these issues disappear, but break the code associated with the RadScheduler and other controls arlready mentioned.

Has anyone else experienced this issue? If so, please provide information about how you resolved, if you did resolve. Thanks in advance for any information you can provide.

[Solved] Adjust width on excel export

When I export to excel the width is always set to 100%. This can be seen by exporting to excel and opening the file in notepad. For example, notice the 100% below:

<table rules="all" border="1" id="ctl05_grdBudget_ctl00" style="width:100%;table-layout:auto;empty-cells:show;">

Is there a way to prevent this? When I set the width in the NeedDataSource handler the grid displays on the page with the set width. However, this does not persist when exported to excel. I have tried setting the width prior to calling MasterTableView.ExportToExcel however this does not seem to make a difference as it is always 100% for the export.

From what I have seen, the only way around this is to set the width of each column which I do not want to do. I want to have the grid auto size when exported. If you edit the exported file and remove width:100% then open it in Excel, it will display the way I would like it to.

The reason I am asking is because the columns are too wide to fit on a single page when you go to print in Excel. Below is the code I am using if it is of any help.

<%--Button to perform the export--%>

<asp:LinkButton runat="server" ID="lnkExport" Text="Export"></asp:LinkButton>

<%--The grid itseld--%>

<telerik:RadGrid ID="grdTest" runat="server">

<MasterTableView AutoGenerateColumns="false">

<Columns>

<telerik:GridBoundColumn SortExpression="Name" HeaderText="Supervisor" DataField="Name" />

<telerik:GridBoundColumn SortExpression="Unconfirmed" HeaderText="Unconfirmed" DataField="Unconfirmed" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Private Sub grdTest_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles grdTest.NeedDataSource

Me.grdTest.DataSource = New List(Of Object) From {New With {.Name = "Name 1", .Unconfirmed = 5},

New With {.Name = "Name 2", .Unconfirmed = 3}}

'manually setting the width, this displays as it should on the page

Me.grdTest.Width = Unit.Pixel(500)

End Sub

Private Sub lnkExport_Click(sender As Object, e As EventArgs) Handles lnkExport.Click

Me.grdTest.MasterTableView.ExportToExcel()

End Sub

Callback error when in Sharepoint 2013 (2010 Compatability mode)

I developed a control to sort and order modules in a document. This is done in a telerik treeview control.

This works fine in Sharepoint 2010. Now I have the requirement to deploy this to Sharepoint 2013, but the site collection is running in "2010 compatibility mode". What happens now is, the page is loaded and I see all the controls. But after the second, sometimes the third click on any button in the treeview (does not affect other standard buttons on the page), the control disappears when trying to rebind. The code behind is executed, but in the browser console (same behaviour in IE/FF) I see errors like
IE: window._WebForm_InitCallback() -> (SCRIPT438: Object doesn't support this
property or method )
FF: init.js -> too much recursion

The control is still "available" in the page source, but seems not to be able to draw itself again. I added screenshots to show the control before and after. The browser shows a long list of maybe 100 entries "WebForm_Initcallback, init.js. This is probably the "too much recursion shown in the javascript debugger.

I started with a 2011 Telerik.Web.UI control version, since this is an old project, but on seeing the error, updated to the latest version 2014.1.225.35. This solution works fine in Sharepoint 2010, and Sharepoint 2013 (site collection in non-compat mode)

I can't pinpoint the error, since it's thrown in minified sharepoint javascript files. Has anyone experienced this problem before?

[Solved] opening contextmenu causes losing the hover style of the target element

Hi All,

I use radcontextmenu on a html table, the table has a row hover style applied which highlights the row when mouse hovers on it. But when right click on the row to open the context menu, the hover style disappears. I have noticed the browser default contextmenu doesn't have this issue. Please see the screenshots and css attached.

.hor-minimalist-b tbody tr:hover td

{

background: #F3E2A9;

color: #009;

}

Thanks in advance,

Jason
