[2005] Gridview Datasource

[Righteous_trespasser]

Hi there, I have got a web-page with a grid view on it, initially there is no data source bound to the grid ... When I press a button, I want the datasource to be set, now I tried the following code but absolutely nothing happens ... where's the mistake that I'm making ... ?

    Protected Sub ButtonSelectCourse_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonSelectCourse.Click
            Label1.Text = "RadioButton1"
            GridView1.DataSource = AccessDataSourceFDES1
            GridView1.DataBind()
            GridView1.Visible = True
            Dim n As Integer = GridView1.Rows.Count
    End Sub

where I say "Dim n as integer = Gridview1.Rows.Count", I just used that to see if there was infact any changes made and the grid was maybe invisible or something, but the count is 0 ...

hmmm... i've never tried anything like this, but i do have a suggestion.

instead of:
GridView1.DataSource = AccessDataSourceFDES1
GridView1.DataBind()

try this:
GridView1.DataSourceID = "AccessDataSourceFDES1"
GridView1.DataBind()

because i assume that AccessDataSourceFDES1 is an actual DataSource object on your page and not something you are creating programmatically.

Yes it is an actual DataSource lying on the page, but the ID thing doesn't work either, and I know the DataSource contains Data ... 12 rows of it ...

Seeing that that way of doing it doesn't really want to work ... how about this ... Is there a way to change the Datasource's query and then just refresh the Gridview?

[Righteous_trespasser]

but to change the query realtime ... (while the page is open) ... so if a user clicks on a button it changes the query and refreshes the grid ...

While this isn't a proper solution to your question, what happens when you attempt to create a regular dataset and bind the gridview to that dataset?

[Righteous_trespasser]

I have found another way ... Each time another option is taken, instead of trying to bind another datasource to it, I just change the Select Query and then DataBind it again ... because they all come from the same database, they just have different queries ...
