[RESOLVED] How to? fill the list box from a particular table based on selection?

[gjon]

I am wanting to select a table for the FROM part:

categoryComm = new SqlCommand("SELECT ListRelationID, ListRelation FROM ListRelationTbl", conn);

based on what value the user selects in a listbox.

How can I replace ListRelationTbl" with the value from the listbox?

" + listboxtableslct.Value + "", conn);

conn.Open();
// Create command to read the categories
reader = categoryComm.ExecuteReader();
// Populate the list of categories
categoryLst.DataSource = reader;
categoryLst.DataValueField = "ListRelationID";
categoryLst.DataTextField = "ListRelation";

Thank you so much in advance.
