Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object

Hello,

I'm trying to get File Explorer hooked up to a SQL Server 2008 database, and I can't get past this error. It displays the folders, and I can see it hitting the database and returning records, but when the page loads it throws this error:

Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object

Does anyone have a solution for this error? Also, the files are being saved as binary streams, so if anyone has any code on how to convert these back into files using File Explorer, I'd be in much gratitude.

Thanks,

Scott

Centering RadDock's Titlebar text.

Hi Telerik,

This should (hopefully!) be really simple.

I have this:

.RadDock .rdTop{text-align:center;}

This does basically what I want -- it centers the title of the RadDock. But, when the calculation is made on where to center it, it takes into consideration the far LHS of the RadDock to the start of the first command on the RHS. This is causing my text to be displayed off-center compared to the content in the RadDock.

Is there a way to do something like text-align:center text-shift-right: 38px? I tried using text-indent, but it seems to indent how far the icons are from the RHS and not the text itself.

Thanks!

Self opening window

Hi

I open my window in code behind using VisibleOnPageLoad and AjaxRequest. I also set a navigation url in this ajax request. When I want to close window I call javascript function on page which was loaded as content of the window. Function look like this:


<script type="text/javascript">
    
    function GetRadWindow() {
        var oWindow = null;
        if (window.radWindow) oWindow = window.radWindow;
        else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
        return oWindow;
    }
 
    function CloseAndRebind() {
        GetRadWindow().BrowserWindow.selectionFinalize();
        GetRadWindow().Close();
        return false;
    }
    
</script>
>

But when window is closed, it opening itself.

bind data to chart

Hi people,

I'm new at this forum, so I hope I post this in the right place. I have a database with several data in. I want to select a data in database with dropdownlist. When you select the value in ddl, the selected data should come to chart.... My example;
- Database: ProblemDescription,
- My Tables: ID, Name, Department, Problems, Description, Date, Hour

I show the items of Department in dropdowlist, what I want is; when you choose a department you must see the Problems in Xaxis and I count the items in Yaxxis. My query; SELECT Department, Problems, COUNT(*) AS totalProblems FROM tblProblemDescription GROUP BY Department, Problems
Does anyone show me a way how to solve this problem with databinding in RadChart.

Tooltipified Radgrid Example

In your Tooltipified Radgrid I have implemented everything that I see.
However, after I load the page, I currently don't databind anything (or retrieve any data) and the tooltip appears as if it's loading and then it disapears a second later. When it disapears, it causes the page to completely referesh.

Any idea what's happening here?

Let me give you a little FYI about my scenario:
This is a user control within a user control. I use a radajaxmanagerproxy object in the user control that represents the tooltip. The first usercontrol is a customized grid that I use through out the web app.

I've registered the tooltip control on the grid control page (which appears to be fine). I've written the events on the the grid page for ondatabind/onajaxupdate simarlily (again just trying to get the tooltip to show up.

Thanks for any help. I'm kind of at my wits end on this one.

Header context menu localization

Hi telerik team

I would like to localize the header context menu items of the rad grid (not grid column headers)

<MasterTableView Name="Class_MasterTableView" EnableHeaderContextMenu="true"

Remarks:

I'm using rad controls for asp.net ajax Q3 2008

framework 3.5
IE 7
windows vista

I post this question later but the reply was describing how to localize grid columns [not grid header context menu] but when I tried to post a reply by following the supplied link, it always give me "the page can not be found"

this occurs since the new web site was published .

thanks in advance

FormDecorator doesn't redecorate text.

Hi All,

I am a bit new working with the RadFormDecorator. I assume I'm missing something trivial, but I couldn't find anything.

I have this:

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">

</telerik:RadScriptManager>

<telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server" DecoratedControls="All" Skin="Web20" />

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<fieldset>

<legend>Settings</legend>

<table>

<tr>

<td class="style4">

Auto-Refresh Enabled:</td>

<td class="style5">

<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" oncheckedchanged="CheckBox1_CheckedChanged" />

</td>

<td class="style6">

<telerik:RadNumericTextBox ID="RadNumericTextBox1" Runat="server" Label="Auto-Refresh Interval:" MaxValue="60" MinValue="0" ShowSpinButtons="True" Value="0" Width="175px" Enabled="False">

<NumberFormat DecimalDigits="0" />

</telerik:RadNumericTextBox>

</td>

</tr>

</table>

</fieldset>

</telerik:RadAjaxPanel>

</form>

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)

{

RadNumericTextBox1.Enabled = (sender as CheckBox).Checked;

}

When the page first loads RadNumericTextBox's Label is grayed out because RadNumberTextBox is disabled. The user checks the checkbox, RadNumericTextBox becomes Enabled, but its font color stays gray.

I know I could just overwrite the font color, but I'm pretty sure this is something RadFormDecorator should be able to handle.

Any ideas?

Thanks
