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.

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?

I use rad scheduler, and I translated the labels of the appointment  to Hebrew.
How can I change the position of the controls so that  the start date  will be before the end date (right to left) ?

thank you

I'm looking for a gauge with multiple concentric circles, each circle showing values of different entities. Something like this...(see attachment)

Here each needle shows value of corresponding entity. I saw some gauges in jQuery & Ajax. So I was wondering if I could find something like this.

Hi all,

 I am new to telerik controls, I am having two RadDatePickers(FromRadDatePicker and ToRadDatePicker) and a TextBox(TotalTextBox).I want the Number of days from the Two raddatepickers to the Textbox. I am getting it by using this below code I also want subtracting the saturdays and sundays and custom holiday list if any.

For Example:-

FromRadDatePicker  31-Aug-2012
ToRadDatePiker     05-Sep-2012

The TotalTextBox Should be 2( 1 and 2-Sep is saturday, sunday and 4-sep is a custom created festival Holiday)

How to create Custom Created Holiday List, and Subtracting the Saturday and Sunday?

Any one Please help me out.

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.

hello,
how to Access NoRecordsTemplate control Using Javascript/jquery?

Hi

I have a RadComboBox with a EmptyMessage and want to clear the content, I've tried:

cboSearchGenre.Text = null;
cboSearchGenre.clearSelection();
and
cboSearchGenre.Text = "";
cboSearchGenre.clearSelection();
and
cboSearchGenre.set_text(cboSearchGenre.get_emptyMessage());
cboSearchGenre.clearSelection();

But I always get a empty ComboBox without the EmptyMessage or in the last example I get a ComboBox with the EmptyMessage as Text content not empty, how can I clear the CombBox and get the EmptyMessage from Client Side?

I am using RadSplitter on my master page for layout. My layout is similar to layout in THIS demo. Thea only difference is that I have one extra pane at the bottom for footer. So, my master page layout would be something like this:

I want NestedSplitter to resize according to ContentPane height, with no vertical scroll bar within ContentPane. I've also found THIS article describing how to accomplish that but I keep getting some JavaScript error: "undefined" is null or not an object. Could you please help me?

Hello,
we are using RadEditor in SharePoint 2010.
If we put the below tags:

<figure class="freestyle left">
       <img src="/csvstories-cookingcaravan.jpg"/>
       <figcaption class="caption">
               Caption Arial Regular 11px #666666<br />
               Image format: Landscape 300 x 180 px
       </figcaption>
</figure>

RadEditor will remove it the final tags and we are not able to use it.
Is there some specific configuration we are missing?

thanks
