Microsoft JScript runtime error: Object doesn't support this property or method

Hi,

I have a page setup that consists of a script manager, tabstrip, a multipage, and two pageviews each with their own distinct ListView bound to independent Linq datasources that are reading two different tables...

There is NO backend code to the project that I'm working on yet; however, when I when I click the edit item button on any of the list items belonging to the listview that is located on the second pageview, I get the following error:

"Microsoft JScript runtime error: Object doesn't support this property or method" From what I can see in the debug window, the error is being thrown at a.beginUpdate(); If I continue past that error, everything seems to load just fine...but I'm not sure that I have any confidence using the RadListView with this error being raised...

There does not seem to be any issue when clicking the edit button on the first listview...I have recreated the project and removed any backend code and stripped it down to the basics and the issue is still there with two list views on the same page...

Does anyone have any idea what needs to be done to solve this?

Thanks.

Docking doesnt save the position

Hi,

i have created a dynamically docking control. At Page_Init (not Postback) I initialize the Docks. But when I move one of the docks every dock is in his start position in the dockingzone after postback, so I can't change the position of the single docks.

ViewState is disabled.

I hope someone can help me. Thx for help.

            <asp:UpdatePanel  runat="server" ID="UpdatePanel1">

Legend Disappears on Postback

Hi,
Im using Promethus RAD chart. In my user control, I have three charts which are dynamically binding and im having different legend for different charts.

In my ascx, i have this much code and im doing all the things in code behind.

<telerik:radchart ID="RadChart1" SkinsOverrideStyles="false" runat="server" Width="600px" Height="430px" seriespalette="" visible="false" >

</PlotArea>
</telerik:radchart>
Legend Creation in code behind:

Dim lbl1 As New LabelItem

With RadChart1.Legend.Items(0)

.TextBlock.Text =

"81 to 100% - Appraisal criteria fully met"

.Marker.Appearance.FillStyle.MainColor = Drawing.Color.Green

.Marker.Appearance.FillStyle.SecondColor = Drawing.Color.GreenYellow

.TextBlock.Appearance.TextProperties.Color = Color.Black

End With

Dim lbl2 As New LabelItem

With RadChart1.Legend.Items(1)

.TextBlock.Text =

"41 to 80% - Appraisal criteria partially met"

.Marker.Appearance.FillStyle.MainColor = Drawing.Color.Yellow

.Marker.Appearance.FillStyle.SecondColor = Drawing.Color.Silver

End With

With RadChart1.Legend

.AddLabel(lbl1)
.AddLabel(lbl2)

.Appearance.Position.AlignedPosition = Styles.AlignedPositions.BottomLeft

.Appearance.Location = Styles.LabelLocation.OutsidePlotArea

RadChart1.Legend.Visible =

True

End With

IN the ascx control, i have combo box with the chart types... when the user changes the chart type and click refresh , then the next chart is loaded. but when the user just changes the chart type alone, then nothing should happen.

actual result : when the user changes the chart type, chart remains the same..but legend text and marker diasppears completely leaving blank white space. but when i click refresh, then legend comes properly.

Is there a way to keep the legend as it is when the user changes the chart type in combo box.

Could you pls.

Thanks

Rad Window close on server side button click event

Let me explain, what I need to perform, I've parent page, on button click show radwindow, I've written the javascript window.radopen("url", null); script. Rad window is opened, and it contains two buttons, undo and continue. When undo button is clicked, it has to close the radwindow and continue button is clicked, it has to close the rad window and redirect to the parent page and update the grid which is there on the parent page.

I've used all the possible code snippets which are posted related to closing of radwindow such as the one shown here : http://www.telerik.com/community/forums/aspnet-ajax/window/radwindow-close-on-server-side.aspx.

To be more clear, I've attached the screen shot of the code snippets which I've written to implement it.

Dynamically creating time slot context menu

Hi, what I am trying to do is create a time slot context menu based upon the selected value of a radcombobox. What I see happening is that the scheduler is bound once but never server-bound again unless I change the selected date or otherwise do some action on the scheduler.

I have tried to fire rebind() and select a date but the binding (whether inside _databound, _init) does not fire.

                    functionschedule.rebind();         
            functionschedule.set_selectedDate("2/3/2010"); //rs.get_selectedDate());         
            alert('rebinded');         

Am I going to need to build the context menu on the client? Does client "rebind()" require a web services datasource?

Thanks, Chip

What version of RadGrid to use

I am running MOSS 2007 Enterprise and WSS 3.0. IIS shows that my sites are running with ASP.NET 2.0 (and no other framework options). Can I just follow the instructions here, http://www.telerik.com/help/aspnet-ajax/moss-install-aspnet-ajax-35.html and then my SharePoint sites will run the RadGrid for ASP.NET 3.5?

[Solved] Toolbar: Change text of existing items -> wrong css class

Hi,

I need to localize the FileExplorer on server side because translations should be user-customizable and therefore are loaded from a database. That works fine except for one problem:

Except for the last item (Upload) in the Toolbar, all other items have the css class: rtbIconOnly set on them. This results in the Text being displayed with 17px height instead of the default and without a space between the icon and the text.

I could work around this issue by applying some custom css, but the 'clean' way would be to remove the .rtbIconOnly css class from the first menu items. Where is this defined, because I can't find out where this is set to change it.

The css I used is this:

    
            /* hack for Telerik file explorer .rtbIconOnly css class to look like normal icon+text buttons: */ 
        
            .RadFileExplorer .RadToolBar .rtbIconOnly .rtbText { 
        
                font-size: 12px !important; 
        
                padding:0 2px 0 22px !important; 
        
            }

Thanks in advance,

Sebastian
