Dynamically Controlling DefaultMode of Formview

Hi All

Me again, I have another question in my journey within ASP.Net2..

I can see what I want to do but at the moment can't see how to achieve it..

I have a Formview control that is databound. What I would like to be able to do is to dynamically set the DefaultMode of the formview depending on the whether the SQLDataSource is full or empty.. ie.

If Empty DefaultMode="Insert" other DefaultMode="Edit".

The way I thought I could acheive this is using the Page_Load event that checks the SQLDataSource and then sets the DefaultMode of the formview.

.. Does this sound right?.. if so how would I be able to check the status of the SQLDataSource?

I think what you need is the ChangeMode method of the FormView class: http://msdn2.microsoft.com/system.we...hangemode.aspx

This method allows you to switch the FormView from one mode to another. The DefaultMode is just, euh, the Default. It has always surprised me a bit that it's called the DefaultMode, and not just the Mode property that allows you to switch by simply changing the property's value....

Hi All

If anyone is wondering how to check if a formview is empty before dynamically change the mode, I used this:

Code:

Protected Sub FormView1_DataBinding(ByVal sender As Object, ByVal e As System.EventArgs)
        If FormView1.DataItemCount < 1 Then
            FormView1.ChangeMode(FormViewMode.Insert)
        Else
            FormView1.ChangeMode(FormViewMode.Edit)
        End If
    End Sub

.. it seems to work.
