errors with System.Data.Datarow

Hi, this is my code:

Dim datarow1 as DataRow

datarow1 = DataSchema1.Clientes.NewRow()
datarow1 = DataSchema1.Clientes.Select("IdCliente=IdClienLabel.Text)
NombreCliente.Text = datarow1("Nombre").ToString

And the DataSchem....select... line gets underlined in blue and it says that "a value of type '1-matrix dimensional of System.Data.DataRow' can't be converted to '2' "

Any clue? Thanks heaps!!

The Select() method of the datatable returns a 1-dimensional array of type DataRow. The following example should give you a guide.

VB Code:

Dim rows() As DataRow
rows = DataSchema1.Clientes.Select("IdCliente = IdClienLabel.Text")
 
If (Not rows Is Nothing) Then
    Text1.Text = rows(0).Item("Nombre").ToString
End If

Hey thanks for your help,

I'm still getting an error, now what if get is from the line that goes ...rows(0)... it says the index is out of matrix range.

What I'm trying to do is to select rows of data applying a filter from my dataset, I thought just defining a variable as datarow and having it contain the results from select() would be enough but I guess it isn't.

Thanks again.

If the number of elements in the array [datarow array] is less than one, it should return nothing -- I think.

May be you should try

VB Code:

If (rows.Length > 0) Then
    Text1.Text = rows(0).Item("Nombre").ToString
End If

Ok yeah, that was the problem the select() method was giving me no results. But now I've tried setting it this way:

Dataschema1.Clientes.Select("IdCliente=4") and it still gives me no results back. And I know there is a Client whos ID is 4. In the table IdCliente is defined as integer.

How come it isn't retrieving the data correctly.?

Thanks lots!!!

Ok, got it! It is because I had to do Dataschema1.ReadXml()

Do I have to read the xml everytime I run a form? Can't I do it at the beginning of the application once for all?

Thanks again
