DataRowView does not contain a property with the name "Name"

Hi,

I have just updated to the Q1 2008 release of both ASP.NET Ajax and ASP.Net toolset. I am going through a number of pages trying to update existing ASP.NET controls to ASP.NET Ajax controls and have succeeded with most, but the ComboBox is giving me a problem.

I have an Object datasource on a page (called dsProfession) which returns a simple datatable, and the ASP.NET combobox was linked to this OK. When I change to ASP.NET Ajax combobox it does not like me just putting in the columns names from the Object datasource as it seems to want to validate them.

Is there any work around for this other than manually assigning the values when the page is opened?

The definition of the Combobox is:

    
            <telerik:RadComboBox ID="ddlProfession" runat="server"   
        
            AppendDataBoundItems="True" DataSourceID="dsProfession"   
        
            DataTextField="Name" DataValueField="GroupRef"   
        
            MarkFirstMatch="True" Skin="WindowsXP" Width="200px"   
        
            AutoPostBack="True"   
        
            ToolTip="Select a Profession for the fee quote line from the drop down list">  
        
            <Items> 
        
               <telerik:RadComboBoxItem runat="server" Text="NONE" Value="-NONE-" /> 
        
            </Items> 
        
            </telerik:RadComboBox>

and the definition for the Object datasource is:

    
            <asp:ObjectDataSource ID="dsProfession" runat="server"   
        
            SelectMethod="ListGroup" TypeName="dbGroup2  
        
            CacheDuration="1800"   
        
            OldValuesParameterFormatString="original_{0}">  
        
            <SelectParameters> 
        
             <asp:Parameter DefaultValue="false" Name="ShowArchived" Type="Boolean" /> 
        
            </SelectParameters> 
        
            </asp:ObjectDataSource>

[Solved] Text value of RadTimePicker control

Hi!

Just a simple question. How do I get the text value of a RadTimePicker control in the code behind? I have searched for it but can't seem to find it. There is a DateInput.Text property but that doesn't show the text written. I must be able to distinguish between an empty control and an invalid one. So, if someone for example writes "xyz" into the control, where do I find this value?

Thanks!

embedded video not working?

Hi,

I encountered a problem when i tried to embed video with the radeditor: the video wont play. So i tried the same with the demo project here: http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx (used the RadNavigation.avi video) but it does not work there either. both in the dialog as in the editor in preview mode.

Tried several computers, IE 6 ,7 and 8.

Video plays fine when opened manually, so its not a codec problem.

I just selected a video and inserted it, did not change any settings.

Anyone know whats going on and how to fix this?

autosize dock to contents

Hi,
I am trying to autosize a raddock to its contents. I have a raddock that contains a grid.
I have just moved to Q3 2009, and was previously using Q2 2008.

I have not entered a value for the raddock height, and this used to autosize the height of the raddock to the grid. This does not seem to happen now..

Any ideas please ?
Many Thanks
Mark

Styles get messed up after grid updates

Hi,

I've got a RadGrid that has filtered columns. When I filter the grid, styles elsewhere on my page go a little haywire and the page doesn't look right.

I've been through all the stylesheets looking for conflicting rules but can't find any. I've attached some screenshots to assist.

Any ideas?

Thanks

In the development environment the Ajax operations work perfectly, but in the Production environment they are consistently unreliable. They work only sometimes. This is evident in that if the Ajax transaction has fired as you will see the RadLoadingPanel. If the Ajax transaction did not fire you will not see the loading panel and you will see the browsers progress bar indicating that the page is doing a regular postback, and of course you will see the entire page reload.

We have issues with scenarios like you select a value from a drop menu and then press an Ajaxified button to send that value and get a response back based on it, and the page does a regular PostBack instead of Ajax transaction, and the default value gets sent not the one the User selected from the drop menu.

In our testing of these issues in the production environment, we have found that if we disable Ajax on these pages, by removing the components from the RadAjaxManager, and republishing the site, we no longer have the problem of the default value being sent instead of the one the User selected. This of course, is not what we want to do. We want to use Ajax in our site.

These issues all happen around Ajaxified controls, and only happen in the Production environment. We have none of these type of issues in the development environment.

We publish the site with VS2005 and test it on a development server here, and everything is perfect, then we copy those same files to the Production Server and we have the issues outlined above.

How can I get to the bottom of this issue and resolve it so we can use Ajax in our site?

Scott.
