ListBox, multiple display members

marikaludmann

I have a dataset/datatable and trying to get it to get the rows of the table to display in a ListBox. My code so far String disp = dt_shared.Columns["FirstName"].ToString() + " " + dt_shared.Columns["LastName"].ToString(); listBox1.DataSource = dt_shared; listBox1.DisplayMember = disp; listBox1.ValueMember = "Email1Address"; listBox1.DataBindings.Add("SelectedValue",dt_shared,"Email1Address"); dt_shared is the datatable and I am trying to first attempt display the FirstName, LastName and EmailAddress on one line, Second attempt (which is not shown here), also display other attributes in the table as part of the Display member. I thought if I can create a string disp, then I can just assign this to DisplayMember and get FirstName, LastName and EmailAddress Displayed. However, it is only displaying the last element (EmailAddress) in the ListBox. How can I have more than one display member? Marika

What I have is a list of Contacts, which I display in a listBox. The listBox can only display one attribute of the contact, in my case I will display the full name. now I also need to display other attributes of the contacts, (beside the name), but these attributes don't have a fixed number. It could be 1 or it could be 20. So if I need to display John Smith [email protected] 21/09/1978 24 Bandor Street London NW8 Eve Gartner NW8 7JJ If I was to display the attributes beside the name in text boxes, could I do that without knowing in advance the number of textfields? Even if this is possible, I would not be able to arrange it on the screen, so it would occupy the same amount of space each time. Whereas a ListView could be made scrollable. Marika

A listview is for displaying lists. Why would you use that if you are already using a listbox? I would suggest using only one list control and several textboxes to diplay the related info. Tony

I just figured, that this is what I will have to do. However I do have to display several other fields (not just first name, last name), but I realised I cannot do that in ListBox. So now I am looking if I can (when an item is selected) display its related attributes in a ListView So listbox would be Jane SMith John coldrow etc. When Jane is selected in the listbox, the listview would display [email protected] 12/12/1988 24 Marsfield Gdns. The details displayed in the listbox for each person (name) are different, depending on what attributes need to be changed. So my next question would be how can I bind the listbox to the listview, to display only data related to the selected item in the listbox? marika

Add a DataColumn to your DataTable and set the Expression property to concatenate the FirstName & LastName columns. Then set the DisplayMember to this new column. Tony
