Context Menu?

Does anyone know if it is possible to use the RAD menu control in conjunction with the chart? I'd like to be able to perform a particular operation depending on which bar is right clicked...

Any ideas / suggestions would be greatly appreciated.

Thanks!

Selected days between months

Hi. I'm programming an application that works weekly, setting the raddatepicker mindate and maxdate between monday and next sunday (I'm from Spain). All works fine for me with the exception when weeks are between two months (i.e. mindate 01/31/2011 and maxdate 02/06/2011). I view in the calendar the final month selected (i.e. february), I can select the previous days of january but I want to view these days "active" (in bold style) like the rest of february days in the same week. How can I do that?

Thanks in advance.

RadGrid : Script controls may not be registered after PreRender.

Hello,

Let me explain my situation I can not solve that contains a RadGrid.

In the name WebUserControl ListTable.ascx I put inside a RadGrid that lists my records and a select button and Delete.

Then I create a control named ViewModules.ascx.

Inside ViewModules.ascx I create dynamically in my div PlaceHolder and using a variable in my QueryString, add dynamically in my ListTable.ascx PlaceHolder.

I put in my Session variable control ListTable.ascx then replaced in the page when I press a Delete event of RadGrid is within ListTable.ascx.

You find my code below because I can not provide an example as it uses several library of our platform.

Have you any idea how to make my event the delete button or trigger and be able to see more control in my page?

You will find 3 screenshots that show you the steps to view my shares.

This error only happens with all Telerik controls. If I use Microsoft's control that we have by default with Visual Studio, my control works without error.

Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

If Me.IsPostBack AndAlso Not Session.Item("ViewModule") Is Nothing Then

ModuleItemPlaceHolder.Controls.Add(DirectCast(Session.Item("ViewModule"), Control))

Session.Remove("ViewModule")

End If

End Sub

Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not Me.IsPostBack Then

Dim site As CMS.Site.Item = CMS.Site.Provider.GetSite(Application)

If Not site Is Nothing Then

InitHeader(site)

If Me.ModuleType = [Module].Enumeration.ModuleType.None Then

' Loading module icons

ViewIcons(site)

Else

' Loading module

ViewModule(site)

End If

End Sub

Private Sub ViewModule(ByVal site As CMS.Site.Item)

Session.Remove("ViewModule")

If Me.ModuleType = [Module].Enumeration.ModuleType.None Then

Response.Redirect(String.Concat(site.Url, "/Gestion/"))

Else

Select Case True

Case Me.ModuleType = [Module].Enumeration.ModuleType.News OrElse Me.ModuleType = [Module].Enumeration.ModuleType.SlideShows OrElse _

Me.ModuleType = [Module].Enumeration.ModuleType.Testimonials OrElse Me.ModuleType = [Module].Enumeration.ModuleType.User

If Me.RecordID Is Nothing OrElse Not IsNumeric(Me.RecordID) Then

Dim ctrl As CMS.Controls.ListTable = DirectCast(LoadControl("~/CMSControls/Generic/ListTable.ascx"), CMS.Controls.ListTable)

ctrl.Module = Me.ModuleType

ctrl.EnableNewRecord = True

Dim handled As Boolean = False

RaiseEvent InitListTable(ctrl, handled)

Session.Add("ViewModule", ctrl)

ModuleItemPlaceHolder.Controls.Add(ctrl)

Else

End If

End Select

End If

End Sub

Problem with calculated column

Hi,
I'm having problem with calculated column in RadGrid (2010-02). Code:

...

<telerik:GridBoundColumn DataField="Quantity" HeaderText="Quantity" SortExpression="Quantity" UniqueName="colQuantity"></telerik:GridBoundColumn>

telerik:GridBoundColumn DataField="Price" HeaderText="Price" SortExpression="Price" UniqueName="colPrice" DataFormatString="{0:C}"></telerik:GridBoundColumn>

telerik:GridCalculatedColumn HeaderText="Total Cost" UniqueName="colTotalCost" DataType="System.Double" DataFields="Quantity, Price" Expression="{0}*{1}" />

...

Columns Price and Quantity are correct, without calculated column it is grid OK, but when I add it, I got cryptic error:

')' or ',' expected

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: Telerik.Web.UI.ParseException: ')' or ',' expected

Can anybody tell me, what's wrong?

Thank you,
Zdenek

RegularExpressionValidator not firing in panel

Hi,

I have a series of RegularExpressionValidators in an asp:panel which is marked Visible="false". This panel is later made visible and the page is updated with a RadAjaxManagerProxy control. When I later submit the form, using a button in the same panel, one of the RegularExpressionValidators does not fire. It does not even fire on the server-side. What can I do to resolve this?

Thanks.

RadAjaxManager causes RadTreeView not to fire.

Hi,

I am having some issues with getting the RadTreeView and RadAjaxManager to work. After the page loads for the first time, I am still able to collapse/expand the RadTreeView that I've added on the page. As soon as I select and item from the dropdownlist to update the RadTreeView, it no longer allows me to expand/collapse or even click the the nodes. I don't get any errors either.

Note that the code below is inside a ".ascx" file which will be used as a SharePoint webpart. I am currently using VS2010, .NET Framework 3.5, MOSS 2007.

Please help.

Thank you so much!

radGrid export to Excel dataSource error

I have a RadGrid that is filled with a SqlDataSource and an Export to ExcelML button that throws the following error when i try to export it:

Telerik.Web.UI.NullEnumerableException: Cannot perform this operation when DataSource is not assigned

There is obviously data in the grid so the DataSource must be assigned. I can find no reference to this error anywhere.

Resizing Problem and AutoResize option

Hi,

I'm testing the new Auto Resize facility and so far, it has not been successful.

    
            function openRadWin(id) { 
        
                        radopen("http://www.telerik.com", "radWindowFareRules"); 
        
                    }

Above is the example test Javascript I used to open my RadWindow.

    
            <telerik:RadWindowManager ID="radWindowManager" runat="server" AutoSize="True"  
        
                            Behavior="None" InitialBehavior="None"  
        
                            KeepInScreenBounds="True"> 
        
                        <Windows> 
        
                            <telerik:RadWindow  
        
                                id="radWindowFareRules"  
        
                                runat="server" 
        
                                showcontentduringload="false" 
        
                                title="Telerik RadWindow" Behavior="Close" AutoSize="true" 
        
                                KeepInScreenBounds="True" Modal="True" Overlay="True" 
        
                                VisibleStatusbar="False"> 
        
                            </telerik:RadWindow> 
        
                        </Windows> 
        
                        </telerik:RadWindowManager>

This is my page content where I have my RadWindows and my RadWindowManager.

When the RadWindow opens up, it does not resize by the content size eventhough I have set AutoSize to be true. I assumed it will do the work and resize itself but it didn't.

So I tried the old method that people said have been useful.

In my default page, I had this code as my javascript code.

    
            <script type="text/javascript"> 
        
                    function openRadWin(id) { 
        
                        radopen("FareRules.aspx?id=" + id, "radWindowFareRules"); 
        
                    } 
        
                    function GetRadWindow() { 
        
                        var oWindow = null; 
        
                        if (window.radWindow) oWindow = window.radWindow; 
        
                        else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; 
        
                        return oWindow; 
        
                    } 
        
                    function resetWindow() { 
        
                        window.setTimeout(function() { 
        
                            var oWnd = GetRadWindow(); 
        
                            oWnd.SetWidth(300px); 
        
                            oWnd.SetHeight(200px); 
        
                        }, 400); 
        
                    } 
        
                </script>

And in my FareRules.aspx page, I had this Javascript

    
            <script type="text/javascript"> 
        
                    function resizeWindow() { 
        
                        window.setTimeout(function() { 
        
                            var oWnd = GetRadWindow(); 
        
                            oWnd.SetWidth(document.body.scrollWidth + 20); 
        
                            oWnd.SetHeight(document.body.scrollHeight + 70); 
        
                        }, 400); 
        
                    } 
        
                    function GetRadWindow() 
        
                    { 
        
                        var oWindow = null; 
        
                        if (window.radWindow) oWindow = window.radWindow; 
        
                        else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; 
        
                        return oWindow; 
        
                    } 
        
                </script>

And on page's body Onload, I called resizeWindow method which seemed to work fine. On execution, the window seemed to resize based on the contents. However, the problem I had with that is that when I close to RadWindow and open it the 2nd time, the 2nd execution opens with the size of the 1st execution and then resizes. So if 1st execution had contents that was in the size of 800x600, then 2nd execution starts as 800x600 and then resizes to the 2nd execution's content which can be like 640x480. I want all the RadWindows to start with it's default small size and then expand to fit the content. Is it achievable?

Please let me know if I made any mistakes or if you require anymore info regarding this problem. I want to find a solution for this.
