Change Grid tool tip from "Drag to group or reorder" to "Drag to reorder"

Hi,

Is it possible to change grid tool tip from "Drag to group or reorder" to "Drag to reorder" only as we are not allowing user to group columns. This tool tip can be seen when you hover mouse cursor on column header on rad grid.

Many thanks.

Unable to use RadFilter with RadGrid

Hi,

We have a scenario here where we are creating a RadGrid and adding it to a ASP.NET Placeholder control dynamically from Code Behind.

But we are unable to use RadFilter with this RadGrid. Loading of RadFilter is based on the example shown in below link.

http://demos.telerik.com/aspnet-ajax/filter/examples/firstlook/defaultcs.aspx

Difference is that we are using it with a dynamically generated RadGrid.

The issue is that when we click on the RadFilter to generate new filter expression it throws an 500 exception. As we have configured AJAX within application we are not able to identify what can be the reason of such an error message.

The error is as below :

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

While debugging we identified that FIlterContainer object is NULL for the RadFilter even when a valid Grid Id is provided. As the Grid is generated dynamically, the ID is assigned from code behind.

Did someone encountered such an issue with RadGrid and RadFilter ? We are highly frustrated with this. Not able to figure out what could be the reason. If there is some issue with dynamic coding............

Any help asap would be appreciated.

Thanks,

Nutan

[Solved] Why GridCalculatedColumn does not display decimal numbers?

Why GridCalculatedColumn does not display decimal numbers?

    
            <telerik:GridCalculatedColumn DataFields="CustomersActivated,Customers" Expression="({0}/{1})*100" DataType="System.Double" DataFormatString="{0:f}" telerik:GridCalculatedColumn/>

For values like 1 and 300 grid displays "0.00" instead of "0.33"

How do I determine if a postback was caused by a node expanding?

I have a load-on-demand tree (i.e. most nodes have node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack). In the Page_Load method how can I determine if the postback was caused by a node expand event?

[Solved] RadGrid DetailTables SelectedValue

I have a RadGrid with a nested DetailTables section, below there's the aspx code.
When the user clicks on a details row I want to get in C# code the DetailsTable selected DataKey or a telerik:GridBoundColumn value. I've tried attaching to RadGridAspnetUsers_ItemCommand event but couldn't find how to get the value.

Telerik Imagemap issues in IE8

Hi all,

I'm using below control in the application.
Telerik controls version : 2008.2.1001.35 (for Telerik.Web.UI.dll)

I'm trying to open an image in image map editor using the telerik controls. I see below error on the screen
-----------------------------------------------------------------------------------------------------------------------------------------------------

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)
Timestamp: Tue, 22 Jun 2010 15:26:48 UTC

Message: Invalid argument.

-------------------------------------------------------------------------------------------------------------- ------------------------------

Investigation:
Based on some calculation, I see some negative value is assigning to a variable _45 in scriptResource.axd in the function wrapwithRoundCorners(). Just for testing purpose, I've modified to a positive value in debug window. I didn't see any issue then. If I left this with -ve value, it is throwing above said error.

Question:
I would like to know whether there are any issues with the combination of IE8 and windows7. Any inputs are appreciable to further proceed on this.

Thanks,
Mallesh.

EditorDialogs folder

Hi Telerik,

We are wanting to modify some built-in dialogs for RADEditor. The version of RADeditor that we have installed is 5.7.3.0 and we have MOSS 2007.
In the instructions it says to copy the EditorDialogs folder to the \wpresources\RadEditorSharePoint\5.x.x.0__1f131a624888eeed\Resources\ directory.

My question is where do I copy the EditorDialogs folder from initially? I can't seem to locate it.

Thanks,
Claudz

RadTabstrip Javascript Error

Hi All,
i am using RadTabstrip in MOSS environment

    
            <PublishingNavigation:PortalSiteMapDataSource ID="SiteMapDS" Runat="server" 
        
                   SiteMapProvider="CurrentNavSiteMapProvider" EnableViewState="true" StartFromCurrentNode="true"   
        
                   StartingNodeOffset="0" ShowStartingNode="false"/>  
        
                 <telerik:RadTabStrip runat="server" ID="RadTabStrip1" skin="Suntab" EnableEmbeddedSkins="false" DataSourceID="SiteMapDS"/>

How ever iam getting an error in Javascript (IE and Chrome ) in ScriptResource.axd

    
            ,set_element:function(_c2){  
        
            this._element=_c2;  
        
            thisthis._element._item=this;  
        
            this._element._itemTypeName=Object.getTypeName(this);  
        
            }

this._element is null or not an object. when i remove the RadTabstrip this error does not happen

Can somebody let me know what could be the reason

Thanks in Advance
Thomson
