Hi:
I have RadGrid with a calculated column with custom aggregate footer.
I am getting a blank screen.

Hi, 
I am using RadGrid and I have  added the  scriptmanager to the page from code, making sure that the  first control on the  form is  always a scriptmanager. However, while loading the  page it works fine but  on postback it  throws the  error "Script Control may not be  registered before prerender". 

 Stack Trace: 

[InvalidOperationException: Script controls may not be registered before PreRender.]
   System.Web.UI.ScriptControlManager.RegisterScriptControl(TScriptControl scriptControl) +349529

I have  used the  control as follows. 

 <radg:RadGrid CssClass="grid_container" ID="grdProperties" runat="server" EnableAJAX="true"
                                HeaderStyle-Wrap="false" BorderWidth="1" BorderColor="#cccccc" ItemStyle-Wrap="false"
                                AlternatingItemStyle-Wrap="false" AutoGenerateColumns="False" CellSpacing="0"
                                CellPadding="0" GridLines="None" AllowSorting="True" EnableEmbeddedSkins="false" EnableAjaxSkinRendering="false" EnableEmbeddedBaseStylesheet="false"> 
                                <ItemStyle CssClass="grid" BorderWidth="0" />
                                <AlternatingItemStyle CssClass="grid_alt" BorderWidth="0"></AlternatingItemStyle>
                                <HeaderStyle CssClass="grvHeadings"></HeaderStyle>
                                <MasterTableView BorderWidth="0" AutoGenerateColumns="false" ItemStyle-CssClass="grid"
                                    ItemStyle-BorderWidth="1" AlternatingItemStyle-CssClass="grid_alt" BorderColor="#cccccc">
                                    <Columns>
                                        <radg:GridTemplateColumn HeaderStyle-Wrap="false" ItemStyle-HorizontalAlign="Right"
                                            HeaderStyle-HorizontalAlign="Right" HeaderStyle-CssClass="grvHeadings" ItemStyle-Wrap="false"
                                            ItemStyle-BorderWidth="0">
                                            <HeaderTemplate>
                                            </HeaderTemplate>
                                            <ItemTemplate>
                                            </ItemTemplate>
                                        </radg:GridTemplateColumn>
 </Columns>
                   </MasterTableView>
            </radg:RadGrid>
 Could you guide me as how I could  handle this exception. 

Thanks in Advance.

Hi, I am using XmlDataSource with RadGrid. I need to use Column's Aggregate functionality to show sum (in footer) in one column. As datasource is XML, grid considers I have all string data even though I have numbers in the column. How can I use Sum Aggregate functionality with Xml data source?

code sample:
<asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/App_Data/data.xml"  XPath="/root/Row"></asp:XmlDataSource>
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="XmlDataSource1" ShowFooter="true">
    <MasterTableView AutoGenerateColumns="False" DataSourceID="XmlDataSource1">
        <Columns>
          <telerik:GridBoundColumn DataField="col1" HeaderText="Product" SortExpression="col1" Aggregate="Count" ...

Thank you,

I recently downloaded the trial version of Telerik Rad Controls for ASP.NET AJAX.  Last week, I was happily developing with the Telerik toolbox in Visual Studio 2008, but this week when Tererik asked me to upgrade to their latest version I chose not to upgrade.  After that, the Toolbox went missing.  Now I can't even use the tools.  How can I get the toolbox back?

I'm wondering why RadInput only exposes one event for key presses? It seems like it should mirror the functionality of other events. Namely, it seems like there should be two events - OnKeyPressing (fires before new value is set and can be cancelled) and OnKeyPressed (fires after new value has been set).

I'm trying to implement a search box and I want the results to appear automatically as the user types into the RadTextBox. I can't use OnKeyPress because it doesn't fire when the backspace or delete keys are pressed. Even if it did, the value of the textbox hasn't been updated yet so it still wouldn't work. I need "OnKeyPressed" that fires any time any key is pressed and contains the new value of the input control.

Alternately, it might be nice if OnValueChanged actually fired when the value changed instead of when the control loses focus (isn't that what OnBlur is for?).

I have encountered a very strange problem applying a custom skin to a group of RadDatePickers.

Here is my mark up that causes the error.


Looks simple enough but does not render correctly

Error

What is bizarre about this error, is that if I remove the skin related code from ANY ONE of the controls, they all work correctly again.

In this example I have removed the code from the second RadDatePicker.


Running this code results in this image

Image 2

LIke I said above, I can remove that skins code from any one of the rows, and they will all work again.

This is one of the more bizarre errors I have seen in ages. Is this a bug of the RadDatePicker?. Is there another way to apply the skins that might not result in the error?

I am writing to ask if it is possible to add the Futura font type for the Rad Button control;

Working with the Rad Button, and the Font-Names dropdown list - I did not locate Futura as a built-in Font-Name option;

Any insight is appreciated;
