I tried this solution given in the below link. Which did not work.
http://www.telerik.com/help/aspnet-ajax/radpanelbar-dynamically-created-radmenu.html

Unable to see the menu on top of RadPanelBar1 and only able to see only 1 submenu item "Child 1" if i donot set myMenu.Width to 100%.
I donot want to increase the height of the panel as I have some other items to be shown below myMenu.
Please help me.

CDN fallback

If the telerik static CDN is not available, will it fallback to pulling the CSS from my server? If not, is it feasible for you to add that feature? Even though it is not likely that the Amazon CDN would not be available, you can never completely rely on cloud services, as seen from the recent Azure downtime. I would appreciate your thoughts on this one.

RadControls doesn't work when ViewPage applying MasterPage

Hi,

I was trying to add RadControls into my ASP.NET MVC Page but failed. Finally, I was found the reason is that when ViewPage applying any MasterPage. The page will always get "Validation of viewstate MAC failed" error after PostBack. See below:

---

Server Error in '/' Application.

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

Source Error:


            Line 113:            // Tracing requires Page IDs to be unique.
Line 114:            ID = Guid.NewGuid().ToString();
Line 115: ProcessRequest(HttpContext.Current);Line 116:        }
Line 117:

Source File: D:\Projects\TEST\SystemWebMvc\Mvc\ViewPage.cs Line: 115

I was tried to do any possible modification but still can't solve this problem.

Does anyone know how to overcome this situation?

Thanks.

2 questions: Master-Details and validation.

Hi.
My first question is about Master-Details grid:
I've created a hirarchial grid where the details table is a many-to-many junction talbe (i.e - master is custumers, details is customerToProduct) and all the details have is a single dropdown column with the name of the detail.

My problem is that if I set the AutoGenerateEditColumn to True, I also get an Edit column in the details grid, that I don't want.
My question is How can I set the edit column only for the master table?

My second question is about validation. I used the code examples provided by telerik to add a RequiredFieldValidator to a textBox column, and with a little t & e managed to adapt it also to Numeric columns and DateTime columns.
Now I have 3 methods, each for every column type mentioned about (text, numeric, and datetime).
My problem with that is that all of these 3 methods have almost the exact same code, except for the editor part - see attached snippet:

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
        Dim item As GridEditableItem = CType(e.Item, GridEditableItem)
        Dim editor As GridTextBoxColumnEditor = CType(item.EditManager.GetColumnEditor("ContactName"), GridTextBoxColumnEditor)
        Dim cell As TableCell = CType(editor.TextBoxControl.Parent, TableCell)
        Dim validator As RequiredFieldValidator = New RequiredFieldValidator
        editor.TextBoxControl.ID = "ID_for_validation"
        validator.ControlToValidate = editor.TextBoxControl.ID
        validator.ErrorMessage = "*"
        cell.Controls.Add(validator)
    End If

for Numeric column I use Dim editor As GridNumericColumnEditor = CType(item.EditManager.GetColumnEditor(ColumnUniqueName), GridNumericColumnEditor)
and for DateTime column I use Dim editor As GridDateTimeColumnEditor = CType(item.EditManager.GetColumnEditor(ColumnUniqueName), GridDateTimeColumnEditor)

My question is how can I use a single method to attach a required field validator to all kinds of built-in columns of the grid?

Saving/Restore group collapse state

With the GridSettingsPersister class, I can save the group by expression and it works great.

In addition, I have a situation where the user wants to save the collapse state of some of the groups. Is this possible?

For example, the user will:

1. Group the list by 'project status'
2. Collapse specific groups (i.e. Pending, Cancelled)
3. Go into the details screen (i.e. another page so I store the gird settings here)
4. Go back to the list (where I need to restore the grid settings)

At step 4, all the specific groups that have been collapse are now back to their un-collapsed state.

Thoughts?

Thanks,

Loy.
