Hello,

I'm in the process of putting together a rad grid which contains approx 28-30 columns, and I need to change the column headings for 25 of the columns dynamically.

I have managed to sort the renaming when it's just showing the data, but when it goes into edit mode, using the "EditForms" mode, the titles revert back to the original coumn names.

E.g:

In the grid, I have a column called "Group 1", which gets renamed to "UK", but when it goes into the Edit Form, it goes back to "Group 1".

If you can give me any pointers, I would be very greatful.

Thank you

Dave

[Solved] How to keep an item in insert/edit mode?

hi all,
on ItemInserted and ItemUpdated events we can use:
e.KeepInInsertMode = True
and
e.KeepInEditMode = True
where e is defined as
Telerik.Web.UI.GridInsertedEventArgs
or
Telerik.Web.UI.GridUpdatedEventArgs

but in my case i'm using InsertCommand and UpdateCommand, which use e as GridCommandEventArgs
and i need in a particular condition to keep the item in insert/edit mode, how can i do this??

thnx in advance

Grid, Ajax and Detail... getting lost...

Hello,
I'm trying to implement an ajax solution, but having done SL for 2 years it's hard for me.... maybe I've lost something...
my question is : To correctly have a detail view binded to a datasource I need the data in this form :

    
              [DataContract] 
        
                public class Utente 
        
                { 
        
                    [DataMember] 
        
                    public string Codice { get; set; } 
        
                    [DataMember] 
        
                    public string Descrizione { get; set; } 
        
                    [DataMember] 
        
                    public string PWD { set; get;} 
        
                    [DataMember] 
        
                    public string Filiale {get;set;} 
        
                    [DataMember] 
        
                    public List<Gruppo> GruppiAppartenenza { get; set; } 
        
                }

Or Having them Plain (No List<Group>) but [DataMember] int idgruppo.... [DataMember] string descrizione?

How ho I remove from showing the similar row in the second case?

User control edit form - bind data upon event

consider the following example: http://demos.mcmscontrols.com/ASPNET/Grid/Examples/DataEditing/AllEditableColumns/DefaultCS.aspx

I have the same requirement with one exception, when the value in "Supplier" ComboBox changes,
"Category" should have a different set of options (according to the selected value in "Supplier"),
while values in other controls must not change.

can it be done?

ListView "Edit and Insert Templates" with MVC

We would like to implement the same functionality of the "Edit and Insert Templates" demo
http://demos.telerik.com/aspnet-ajax/listview/examples/templates/editinserttemplates/defaultcs.aspx
, but rather than control the binded with SqlDataSource as shown in the example, our control binding occurs in the code behind of a .NET Model View Presenter (MVP) architecture. We can't seem to find any method or property that indicates the item index when a item in the is selected., when the "Edit" button is clicked. So, there doesn't seem to be a way to determine which "Edit" button was clicked and which item to edit.

Do you have an example the the ListView functionality at http://demos.telerik.com/aspnet-ajax/listview/examples/templates/editinserttemplates/defaultcs.aspx only in a MVP structure?

Thanks in advance,

Keith E.

Hide paging

Hi -

I use the following code to implement add/ insert with FormTemplate and EditFormSetting. Everything work well but I would like to hide the paging when the user is in "Add or Insert mode". The goal is to give the appearance that the grid is completely hidden when in these modes. The header disappears but not the footer paging.

Thanks in advance

Not working EXpand/Collapse in Dynamic created columns

hi all,
I created one rad grid at dynamically. Rad grid fixed static and dynamically added columns in page_load event. For more information about this work around is specified my last post the follwoing thread:

http://www.telerik.com/community/forums/aspnet-ajax/grid/dynamic-template-column-for-command-not-firing-event.aspx

Now i can view hierachical grid accoriding to the xml i gave. with expand and collapse button. But when press expand button it showing the even validation error. if evenvalidation = false showinf somw 'Is Operator' error. I think because of not haveing view state or somw thing like So can you please tell how can i explicetly handle expand and collapse or any other solution to handle this?
