I have a function that resides in a class, in my aspx.vb file I want to call the function on a button click event.  The function invokes a web service and will return y or x depending on the input.  My question is how can I bind y or x to a gridview.  

so In my asp.vb file I have:        
LimitByCompanyCode.GetLSODataset(txtBeginDate.Text, txtEndDate.Text, radioSelection.SelectedValue)

'So how can I get whatever the function returns and show that in my gridview?

it seems your webservice returns a dataset so you should call it like this


dim ds as DataSet= LimitByCompanyCode.GetLSODataset(txtBeginDate.Text, txtEndDate.Text, radioSelection.SelectedValue)

if ds.tables.count > 0 then

myGridView.DataSource=Ds.tables(0)
myGridView.DataBind()

end if

I've been trying that... I get the following error: Value of type 'System.Data.DataTable' cannot be covnerted to 'System.Data.DataSet'.

I'm gunna take a wild guess and say your function "LimitByCompanyCode.GetLSODataset" returns a System.Data.DataTable, note a System.Data.DataSet. Check into that. If it does return a table, either change it to a DataSet, or, if that's not appropriate, declare a new DataSet and add the table to it. That will look like:

Dim someSet As New DataSet;
someSet.Tables.Add(LimitByCompanyCode.GetLSODataset( /*Overloads*/ ));

Hope that helps,
Nate

I see,

in 2.0 it allows to return a datatable. (however, in 1.1 there was restriction that you can only return a dataset)

so try

dim dt as DataTable = LimitByCompanyCode.GetLSODataset(txtBeginDate.Text, txtEndDate.Text, radioSelection.SelectedValue)


-thanks
