TabStrip With Multipage - Controls not rendering when Within RadGrid

Hi,

I have a RadGrid within which I use Tabstrip with Multipage as Edit FormTemplate. But when I Change the tabs (OnTabClick) its throws an Object Reference Error.

Below is the stack Trace of the errror

Source: System.Web

Message: Exception of type 'System.Web.HttpUnhandledException' was thrown.

Stack trace: at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.assetresource_manageresource_aspx.ProcessRequest(HttpContext context) in c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\1d05cdea\b7de89b2\App_Web_d4fj34vj.0.cs:line 0 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Probably the multipage controls are not yet intiated at the time of tabclick. Not sure how this can be resolved. I am using stable release of Telerik Q3 2011

Any support/help is appreciated. Let me know if anyone needs markup/codebehind pasted over here.

Regards,
Pratik.

Application Wide Settings

I am currently updating the RadSpell to the latest version in one of my projects. With the older version, I was able to specify application wide settings in the ConfigFile.xml file. It appears that this feature has been removed.

Is there anyway to set properties application wide so that I don't have to specify the same settings over and over again throughout the application? For example, let's say that I wanted to change the default values for WordIgnoreOptions and FragmentIgnoreOptions. I would like this to be consistent throughout the application. It would be nice if I could specify this just once (like I was able to with ConfigFile.xml) and not have to worry about setting the same values for every instance of RadSpell.

I would also like to be able to use the current culture for the Language and DictionaryLanguage properties. I realize I can do this in code for each instance of RadSpell, but I'm looking for something a little more DRY.

Thanks,
Tim

Moving an Application From IIS 6 to IIS 7.5

Hello everyone!

Please, please, please help me!

I moved an application (. Net) IIS 6 to IIS 7.5 (Windows Server 2008 R2).

All the application works, but not that involving the Telerik controls.

An example is when I click the button below!

"
<asp:Button ID="SearchButton" runat="server" CssClass="buttonStyle2"OnClick="SearchButton_Click" OnPreRender="ButtonDisablePreRender"Text="Searchr" />
"

Have tried to update the Ajax Toolkit!

I do not know what else to do!

To be honest I've tried everything!

I am almost giving up, please help me!

The version of telerik is "2011.1.614.35."

RadSpell

I'm not sure if this is the right thread for my question.

Anyway, why is it that RadSpell control doesn't display a "red line" below those mispelled words ?

Expanding DetailTable clears bound items on Master

Hi

I have a problem I can't seem to work out.

Basically I have a MasterTableView / DetailTable relationship. In the master table I am changing the checkbox to an image at the ItemDataBound event - this works fine.

However, when I expand the DetailView the images are removed and the checkboxes re-appear (coincidentially they are always unchecked).

Does anyone know how I should handle this situation so that when the details view is expanded the tick box images remain in the parent MasterTableView?

Many thanks
Carl

protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

var row = item.DataItem as Reporting.EntityModel.Stock;

if (row != null)

{

item["Active"].Controls.Clear();

if (row.Active == true)

{

item["Active"].Controls.Add(new Image() { ImageUrl = "/Assets/Images/tick_small_col.png" });

}

else

{

item["Active"].Controls.Add(new Image() { ImageUrl = "/Assets/Images/cross_small_col.png" });

}

Also, it is showing my URL field. How do I set the DataNavigateUrlField property so they work properly?

Thanks!

Strange visual distortion

I've noticed sometimes when using the Telerik components we get some "visual distortion", which I think is best described by this image:

http://screencast.com/t/pzDqpbhWMw

In short, it seem to be a small black square that shows up sometimes. In this case, it is with a RadRotator, but doesn't show up for all the items. We've seen this with other telerik components as well from time to time. We have tried with several different browsers, and made sure they were set to 100% zoom.

Any ideas?

Or do we have to use a third party jQuery plugin?

Thanks in advance for your help
