GridTemplateColumn dissapears after postback

I am using Telerik.Web.UI 2009.1.311.20. I have a grid in a master page and I am creating its structure and populating it from the content pages. This is the code I use in a content page:

    
            protected new void Page_Load(object sender, EventArgs e) 
        
                { 
        
                    ContentPlaceHolder cph = Master.Master.FindControl("PageContents") as ContentPlaceHolder; 
        
                    RadGrid grid = cph.FindControl("RadGrid1") as RadGrid; 
        
                    if(!IsPostBack) 
        
                    { 
        
                        DefineGridStructure(grid); 
        
                    } 
        
                    PopulateGrid(grid); 
        
                } 
        
                public override void DefineGridStructure(RadGrid grid) 
        
                { 
        
                    grid.MasterTableView.DataKeyNames = new string[] { "CustomerID", "Name"}; 
        
                    GridBoundColumn boundColumn; 
        
                    GridTemplateColumn templateColumn; 
        
                    boundColumn = new GridBoundColumn(); 
        
                    grid.MasterTableView.Columns.Add(boundColumn); 
        
                    boundColumn.DataField = "Name"; 
        
                    boundColumn.HeaderText = Resources.Strings.Name; 
        
                    templateColumn = new GridTemplateColumn(); 
        
                    grid.MasterTableView.Columns.Add(templateColumn); 
        
                    templateColumn.DataField = "CustomerId"; 
        
                    templateColumn.HeaderText = ""; 
        
                    templateColumn.AllowFiltering = false; 
        
                    templateColumn.ItemTemplate = new ImageLinkTemplate("CustomerId", "~/Images/View.gif", 
        
                        "CustomersView.aspx", Resources.Strings.View); 
        
                } 
        
                public override void PopulateGrid(RadGrid grid) 
        
                { 
        
                    CustomerService service = new CustomerService(); 
        
                    grid.DataSource = service.GetGridData(base.GetCompanyId()); 
        
                }

The problem I have is that whenever I do a post back (by sorting the grid or navigating to a different grid page), the GridTemplateColumn is no longer shown. Any suggestions on how to fix this?

RadGrid ViewState off (CommandArgument)

Hi,

I want to use RadGrid with ViewState set to false. Each of my grid row has some text of data, a serverside hyperlink and button?
How can I subscribe to these events as the CommandArgument that is retrieved on ItemCommand is null?

What's the workaround for this? Any pointers in this direction is greatly appreciated?

Regards,
Rajesh

Could you help me to understand what is happened?

Thanks in advance!

[Solved] FireFox DatePicker?

Is the Popup Calendar broken for FireFox in the DatePicker control? It seems to work in IE. Do I have a bad install/config? I have the classic RadControls running in the same app. I also had promethus running and upgraded it to the latest RadControls. Other controls in this new version seem to work fine. I've always used the DatePicker from classic (which works in firefox & ie) but now trying to upgrade my whole app to the latest RadControls. However, if the Popup Calendar is busted in FireFox I can't overhaul to the latest RadControls :/.

Minutes Per Row Issue

I recently upgraded to the AJAX Q2 2008 controls.
When I did a strange problem started happening. The rows per minute on the scheduler control started doubling. When i put in 5, the scheduler shows 10. When I put in 10, the scheduler shows 20 minutes per row.
I've debugged and can watch the value being set on the scheduler and it doubles that value.
Is anyone else having an issue with this property of the control?
Thanks....

Javscript Error on Drag Drop - TrackChanges?

Hello,

I'm getting a "null" or not an object error when the javascript gets to this line:

firstTreeView.trackChanges();

I'm trying out the TreeView component in the 2009 Ajax controls with Visual Studio 2005. I used the example vb files. Then, deleted the qsf references because I wasn't sure how to fix them. The demo code works for the text box and the grid, but whenever I drag and drop an item from one treeview to the other, it doesn't complete and I notice the JavaScript error. I traced it this line using alerts.

Is there sometime of setup that's required to get this to work?

Thanks,

Mike

[Solved] Rating or Slider in Grid

Hi All,

I want to implement an Ajax rating control in my Grid. My initial idea is to include the rating control from the MS AJAX toolkit, but will happily settle for a telerik slider instead. I hope this has been posted and resolved before, but can't find any references.

"Out of the box" / Workaround or not possible.

Links, guidance or alternatives will be gratefully received.

Cheers.
