Custom parsing while data binding with entity framwork

Hi there,

I developed some projects with entity framework up till now - so my skills with this technology (WPF/WinForms) are quiet good. But I'm rather new to ASP.net. In WinForms there are two events for data binding "Parse" and "Format" and in WPF we have custom implemented IValueConverts. But what ways are there in ASP.net (not MVC)?!?

I successfully attached an EntityDataSource to a RadGrid. Inserts/Updates/Deletes are working as expected! But trying to implement some piece of user defined value parsing drives me crazy!

For an example I give you the following column definition:

<

EditItemTemplate>

<asp:TextBox ID="TextBoxPrice" Text='<%# Bind("Price", "{0:#.00} €") %>' runat="server"></asp:TextBox>
</EditItemTemplate>

As you can see, there is a value from the data source (property 'Price') bound with formating information to an appropriate TextBox control. But when I try to update - of course - the operation fails. The string "10,00 €" could not be parsed as an numeric value. Now I would expect an event wich gives me the instance of the current bound item or a value that I can change - anything to customized changing string "10,00 €" to "10,00" or custom filling values to the object. But I can't find anything related :-S

Am I missing something here???

Best regards,
Oliver

[Solved] how to hide EditForm templatae after updating or inserting is accomplished

Hello... I am using a custom template for editing or inserting elements in a grid. I implemented the UpdateCommand where I call a stored procedure in order to add or update information.

Before that event returns, I am calling Rebind method of the grid which causes the edited item be refreshed, but the edit form remains visible. How can I hide the edit form?

Any help will be greatly appreciated.

Thanks
Jaime

Switching between edit modes

I have implemented the "Edit on Double-click" functionaliy found in the online demo for my grid, but I need users to be able to edit in popup mode using a form template if they click a button column that I have added. That same popup needs to be used for new item inserts as well.

Here is the column I added:

    
            <telerik:GridButtonColumn ButtonType="LinkButton" CommandName="Edit2" Text="Edit2"></telerik:GridButtonColumn>

and here is the code behind:

    
            Protected Sub radgridItems_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs)  
        
                    If e.CommandName = RadGrid.InitInsertCommandName Then 'add new item clicked 
        
                        If radgridItems.MasterTableView.EditMode <> GridEditMode.PopUp Then 
        
                            radgridItems.MasterTableView.EditMode = GridEditMode.PopUp 
        
                            radgridItems.Rebind() 
        
                        End If 
        
                        e.Canceled = True 
        
                        e.Item.OwnerTableView.InsertItem() 
        
                ElseIf e.CommandName = "Edit2" Then 'custom button 
        
                        If radgridItems.MasterTableView.EditMode <> GridEditMode.PopUp Then 
        
                            radgridItems.MasterTableView.EditMode = GridEditMode.PopUp 
        
                            radgridItems.Rebind() 
        
                        End If 
        
                        radgridItems.MasterTableView.Items(e.CommandArgument()).Edit = True 
        
                        radgridItems.Rebind() 
        
                    ElseIf e.CommandName = "Edit" Then 'normal edit 
        
                        If radgridItems.MasterTableView.EditMode <> GridEditMode.InPlace Then 
        
                            radgridItems.MasterTableView.EditMode = GridEditMode.InPlace 
        
                            radgridItems.Rebind() 
        
                        End If 
        
                        radgridItems.MasterTableView.Items(e.Item.ItemIndex).Edit = True 
        
                        radgridItems.Rebind() 
        
                    End If 
        
            End Sub

The problem is that the popup does not display when the user clicks the "Edit2" column or when they click "Add new record". Curiously though, the row is highlighted in yellow as if it was set to edit mode. What am I doing wrong here?
