Questions on UI for ASP.NET AJAX Forum

Hello,

Yesterday I upgraded from RadControls for .NET Q1 2010 to the UI for ASP.NET AJAX Q3 2014. I have three solutions which utilize the RadGrid extensively. In my development environment (VS 2010) all of my projects work great. However, when they are deployed to a Windows 2003 IIS 6 server, I am receiving the following errors when I try to sort any RadGrid in my project:

System.InvalidCastException: Unable to cast object of type 'Telerik.Web.UI.RadGrid' to type 'Telerik.Web.UI.GridTableView'. at Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Other basic functions appear to be working properly including rendering of the grid as well as pagination.

Two of the solutions share an application pool on my web server so I though perhaps that might be an issue (even though I know they have their own memory spaces) so I set up a brand new Windows Server 2003 machine patched fully as of this morning. I am still having the error there.

I have verified that I am sending out the correct version of the DLL and verified that my web.config file has the correct entries per the online demos folder installed on my development machine.

Can you please suggest a solution?

Thank you!

RadButton and Overriding Default styles

I am new to Telerik and am struggling with grasping how the styling works with regard to my project.

I have a project using master pages, themes and skins for the various controls (including RadButton). I tried the example on 'Creating a Custom Skin for RadButton' and still found that not all my changes had overridden the Default styles - as I checked it with Firfox's Firebug tool and kept seeing WebResource.axd at the top. How does the WebResource.axd file manage to override some of the styles if I am already got my own custom skin file? Any help would be appreciated.

Thanks

When inheriting from class TelerikSPRadGridWebPart I get reference error

Hi,

I've been trying to create a webpart that inherits from TelerikSPRadGridWebPart. I created an Empty SharePoint 2010 project in Visual Studio and reference Telerik.Ajax.SharePoint from the GAC : C:\Windows\assembly\GAC_MSIL\Telerik.Ajax.SharePoint\2014.3.1024.35__aa9e5f693af67c7b\Telerik.Ajax.SharePoint.dll

I also referenced Telerik.Web.UI (C:\Windows\assembly\GAC_MSIL\Telerik.Web.UI\2014.3.1024.35__121fae78165ba3d4\Telerik.Web.UI.dll)

When trying to build the project, I get this error and this warning :

Error 3 The base class or interface 'Microsoft.SharePoint.WebPartPages.WebPart' in assembly 'Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' referenced by type 'Telerik.Ajax.SharePoint.TelerikWebPart' could not be resolved c:\Windows\assembly\GAC_MSIL\Telerik.Ajax.SharePoint\2014.3.1024.35__aa9e5f693af67c7b\Telerik.Ajax.SharePoint.dll CrossSiteCollectionListViewer

Warning 4 Reference to type 'Microsoft.SharePoint.WebPartPages.WebPart' claims it is defined in 'c:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\SharePointTools\ReferenceAssemblies\Microsoft.SharePoint.dll', but it could not be found c:\Windows\assembly\GAC_MSIL\Telerik.Ajax.SharePoint\2014.3.1024.35__aa9e5f693af67c7b\Telerik.Ajax.SharePoint.dll CrossSiteCollectionListViewer

It seems like a version problem between the Microsoft assembly and the Telerik assembly but I am really not sure. I installed SharePoint (ASP.NET AJAX) with the Telerik Control Panel but I can't find the dll somewhere else than in the GAC.

Maybe someone can help me out here.

Regards,

Martin L.

How do I dissallow specific characters on entry when combo is embedded in grid?

I have a grid with an edit template. In the template I have a combobox that is populated with data from a SQL table, I also have the AllowCustomText="True" set so I can enter values that are not in the dropdown. I want to only allow numeric entries. How can I accomplish this client side with javascript? I can't seem to get it working. Can anyone shed some light on what I need to do?

Here is what I have (I removed the extra columns to shorten the code):

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

var code = eventArgs.get_domEvent().keyCode;

//allow numerics only

if (code < 48 || code > 57) {

sender.returnValue = false;

if (sender.preventDefault) {

sender.preventDefault();

}

Filtering through

Hi, I need to filter the Grid through a Client DataSource in client side.
I can filter the grid applying the filter to the grid directly, however it is not possible filter using non visible columns, so I tried to apply a filter the grid adding filter expressions in the ClientDataSource but nothing happens.
For example
var datasource = $find('MyClientDataSource');
datasource.get_filterExpressions().add({ fieldName: "MyField", value: "MyValue", operator:Telerik.Web.UI.ClientDataSource.FilterOperator.EqualTo });
tableView.rebind();

This code doesnt work. It is possible do this kind of filtering?

Tiles moving to wrong positions

Hi.

I seem to having a small problem here and was wondering if somebody can help me. Whenever I rebind the RadTileList with the "EnableDragAndDrop" parameter set to true, the tiles move to strange places. Here's a screenshot of what happens:

https://www.dropbox.com/s/p7lf15rl16tcuia/Telerik%20RadTileList%20Problem.png?dl=0

When I investigated the HTML that gets generated I noticed that the RadTileList seems to create empty groups for the first couple of tiles and that all the tiles that are outside the current view (those that the user must scroll to see) are still grouped together correctly. Yet strangely, this error only occurs when the "EnableDragAndDrop" parameter is true. If I remove it from the markup the tiles get rendered correctly but then I obviously lose the drag-and-drop functionality which I need.

I am using Telerik Version v2014.1.403.45. Here is the HTML Markup for the RadTileList. The data is allocated via the Databind function.

<telerik:RadTileList runat="server" ID="rtlFavourites" Width="1015px" Height="500px" SelectionMode="Single" AutoPostBack="false" OnClientTileSelected="showContxtMenu" EnableDragAndDrop="true"></telerik:RadTileList>

Any advice?

Thanks!
