Hai One of the form in my application contain a combo box which has the client names currently I coded this like the following comboName.DisplayMember = client_name; comboName.ValueMember = client_id; But I want to show both 'client_name' and 'client_code' in the same combobox that means both 'client_name' and 'client_code' as DisplayMembers if any body have any idea about this please share it.... Thanking you in advance

If you want to use a standard ComboBox rather than the custom one which Pritish appears to be using then you'll need to create a List where each item in the List combines the two fields you want to use for a particular row. Something like the following if the ID is always of a constant width: List list = new List (); foreach(DataRow row in dt.Rows) { list.Add(String.Format({0} {1} row[client_id] row[client_name]); } comboName.DataSource = list; // no need to set DisplayMember and ValueMember properties To get the columns to line up properly you'll also need to use a fixed-width font such as Consolas.

protected override void OnDropDown(System.EventArgs e){ Form parent = this.FindForm(); if(this.dataTable != null || this.dataRows!= null){ MultiColumnComboPopup popup = new MultiColumnComboPopup(this.dataTable ref this.selectedRowcolumnsToDisplay); popup.AfterRowSelectEvent+= new AfterRowSelectEventHandler (MultiColumnComboBox_AfterSelectEvent); popup.Location = new Point(parent.Left + this.Left + 4 parent.Top + this.Bottom + this.Height); popup.Show(); ===== multiColumnComboBox1.Table = dtable;//DataTable //Column to display after selection multiColumnComboBox1.DisplayMember = Band; multiColumnComboBox1.ColumnsToDisplay = new string[]{BandSongAlbum};//columns to display //in the dropdown grid
