Hi

I have a tableadapter already created by the wizard in dataset. I have to add a 'Where xxx In (y1, y2...etc)'. I tried many way like adding a string parameters, but did not work.

How to solve this?, so I can write something like:
myTableAdapter.Fill(dsMainFormReport.tbTheTable, strWhereClause);

Regards

You could extend the TableAdaptor object with this proc

public int FillBySelect(SomeDataSet.SomeDataTable Table, string
Select)
{
this.Adapter.SelectCommand = new SqlCommand(Select,
this.Connection);
if (this.ClearBeforeFill)
Table.Clear();

return this.Adapter.Fill(Table);
}

Open your desired dataset designer .At the bottom where the fill is shown...Right Click ..add new query, then you will see a selct statement..add a where clause Like this....:
Where Lastname=@Lastname (for example)..Contunue with the wizard..and click finish.
then in a form Load or wherever you want call the table adapter as you said initially with the desired parameter...

Dear All I am not that guru. Till now I did not get it very well. my mind got crazy about this subject. I did not even try to open the wizard's code before. If I want to add such as "Where xx = @yy" it will be easy, But to use "In (y1, y2...etc)", I couldn't. btw, I hear about LINQ, but I did not use it before. Regards
