View 1 RepliesI have a problem with a combobox. I have a form (with information about clients) with textboxes binded to a dataview. One of the columns in the dataview contains a number that tells me what kind of client it is. I don't my users want that my users have to fill in a number in a textbox, but I want them to choose a item from a combobox. De selected value should be the value that is actually saved in the database.
This is my
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
VerbindingMaken()
cmd.Connection = cnnVraagbaak
cmd.CommandType = CommandType.StoredProcedure
[Code] .....
De Datasource is the information in my combobox. With Databindings I'm trying to bind it to my dataset (or view, that doesn't work either) with clients. Every time I get a NullReferenceExeption. The moment I remove the line cbo.DataSource = dsRelatie.Tables("Relatiesoort"), I don't get an error, but it doesn't work either.
That dataset is filled (I've checked) and also the derived view. The column Relatiesoort exists. What do I have to do to make it possible for my users to choose an item from a combobox and save the selected value to the underlying dataset?

cmd.CommandText =
"select * from warehouse where x value ='" + ComboBox2.Text + "'" is that possible ?
