Hello,
My issue is that when coming from anoher page with a Sesssion variable holding a specific DataKeyName I am unable to see the selected item unless the item is on the current page. I want to know if there is a function like NavigateAndSelect(DataKeyName) that allows me to first navigate to the specific page and then select an item on that page. If no suh functionality is available then is there a workaround for this?
Best solution for us at this moment is a server-side solution.

Thank you

RadGrid entirely in the code behind 'No Rows' Issue

I have created a hierarchical grid entirely in code behind. On a grid partialy created I get the mouse over effect of the row changing colour, however with this grid I do not. Any help with this would be most appreciated. I have tried the example where you set the http://www.telerik.com/help/aspnet/grid/grdsetstyleonmouseover.html, but I get an error 'this.Row is undefined'

session timeout causes postback?

From what I understand, the way the demo is set up, when the 'Continue Session' button is clicked, a callback should reset the session on the server, meaning the entire page should not be refreshed. And indeed I do not notice a page refresh on the demo. Yet, my page refreshes every time the session is continued. Is there a way to reset the session without this page refresh?

Numeric Textbox losing css class on mouse over

Hello Telerik support,

We have several numeric textboxes throughout our web application and we added our own styling to them through adding a css class to them ("moneybox"). However, they lose this added class after a mouse over.
I think the problem lies with the fact that you change the css classes with Javascript on mouse over and mouse out, and then forget to re-attach the user-added css class.
How can we solve this problem? Besides the solution we have implemented now, which is, adding the css class again after the mouse over through the use of Javascript (jquery), as you see below:

<Telerik.Web.UI.RadNumericTextBox ID="tbActivityValue" Culture="nl-NL" CssClass="moneybox" NumberFormat-DecimalDigits="2" runat="server" MinValue="0" TabIndex="1"></Telerik.Web.UI.RadNumericTextBox>

Added jquery:
/* Add class moneybox to the Telerik Numeric Textboxes in the repeater */
        $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").addClass("moneybox");
        $(".numerictextboxholder .riTextBox.riHover").mouseout(function() {
            $(".numerictextboxholder .riTextBox.riHover").addClass("moneybox");
        });
        $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").mouseout(function() {
            $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").addClass("moneybox");
        });
        $(".numerictextboxholder .riTextBox.riHover").mouseover(function() {
            $(".numerictextboxholder .riTextBox.riHover").addClass("moneybox");
        });
        $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").mouseover(function() {
            $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").addClass("moneybox");
        });
        $(".numerictextboxholder .riTextBox.riFocused").blur(function() {
            $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").addClass("moneybox");
        });
        $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").blur(function() {
            $(".numerictextboxholder .riTextBox.riEnabled.sfi_textbox").addClass("moneybox");
        });

Radchart - Pie chart Legend not as expected

Hi

I was trying to generate the Pie chart. Everything was fine except the Legend. It is giving me - Item1, Item2 Item3 etc instead of actual item values...

Have look at the code,

        Dim chaSer As New ChartSeries
        radChart.AddChartSeries(chaSer)
        radChart.ChartTitle.TextBlock.Text = "Polling Result"
        radChart.Skin = "WebBlue"
        radChart.Attributes.Add("Palette", "Colorful")
        getRespDt()

            chaSer.Type = ChartSeriesType.Pie
            chaSer.DefaultLabelValue = "#%"
            chaSer.Appearance.ShowLabels = True


        chaSer.DataYColumn = "Count"

        chaSer.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels

        radChart.DataSource = dtPoll
        radChart.DataBind()

        Response.ContentType = "image/png"
        radChart.Save(Response.OutputStream, ImageFormat.Jpeg)

Thanks,
Pradip

RadGrid Expression Problem in HelpDesk

Dear Telerik-Team,

I purchased the Premium Collection and want to update my applications I dveloped on the "Demo"-Dlls.

I have downloaded the latest build of the Telerik WebMail demoapplication and I wanted to include the purchased Telerik.Web.UI DLL in order to get rid of the demo hint which is displayed when using the demo-dlls.

I didn't do any changes to it, but when running the default.aspx file, I get an error saying: "The column [Received.Value.Date] could not be found". When I comment the GridCalculateColumn for grouping the date, but still have the one for the conversion-column, I get an error saying that the function call to "Subject.Replace" is invalid. Now, I switched to the markup code and think that the problem comes from this code:

    
            <telerik:GridCalculatedColumn UniqueName="Date" DataType="System.DateTime" DataFields="Received" 
        
                                        Expression="Received.Value.Date" HeaderText="Date" Visible="false">  
        
                                    </telerik:GridCalculatedColumn> 
        
                                    <telerik:GridCalculatedColumn UniqueName="Conversation" DataType="System.String" 
        
                                        DataFields="Subject" Expression='Subject.Replace("RE: ", "")' HeaderText="Conversation" 
        
                                        Visible="false">  
        
                                    </telerik:GridCalculatedColumn>

When I replace the new DLL (I purchaed) to the demo dll, everything goes right. So I guess that something in the DLL has changed. I have made several changs, but did not have any success.

So I would like to ask you if you can help me with this issue?

Kind regards,
Best wishes from Germany,
Marco

Quick calendar variable question

How can a client send dates to my calendar via variable?

example of what im talking about.

http://host.com/calendar.aspx?Date=2011,10,03

or similar?

they are planning on running a script that pulls information from my calendar... how can I allow them to do this?

i'm not too concerned about the format, i want to simulate if they actually clicked on the date.

also, is there a way to do a RSS type feed?
