I have a combobox and i m populating it from DB
Like this,i called it in load event

Categorycls c = new Categorycls();
 comboBox1.DataSource = c.GetCategories();
  comboBox1.DisplayMember= "Category Description";
   comboBox1.ValueMember = "CatID";

and GetCategories is as

public DataSet GetCategories()
        {
            d = new DBConnection();
            d.OpenConn();
            select = new OleDbCommand();
            select.CommandText = "Select * from [Categories]";
            select.Connection = d.getConnection();
            adapter = new OleDbDataAdapter(select);
            adapter.Fill(ds, "Categories");
            return ds;
        }

the problem is arising that on load it displays and error "cannot bind to new display member.
Parameter name: newDisplayMember
The column names are same as of DB
Can any one tell the reason and solution?
Regards

Can you also post your database table structure as I think the DisplayMember is not set to the correct column.

The Problem is your getting catefoiries in Dataset and the Combobox is accepted only in table.

Try this line

MIDL

Categorycls c = new Categorycls();
 comboBox1.DataSource = c.GetCategories().Tables[0];
  comboBox1.DisplayMember= "Category Description";
   comboBox1.ValueMember = "CatID";
