Question

I know for a fact that the function below (Database.GetTables) is bringing back the value/s that I want. However, when I try to do the binding to the list box, nothing populates in it. Am I missing anything? What’s the correct way to populate a list box from a datasource?

protected void ddlDatabase_SelectedIndexChanged(object sender, EventArgs e)
{
     if (ddlDatabases.SelectedIndex != 0)
            {
                lbxTables.DataSource = Database.GetTables(ddlServers.Text, ddlDatabases.Text);
                ddlDatabases.DataValueField = "name";
                ddlDatabases.DataBind();
            }
        }

I have also tried:

ddlDatabases.DataTextField = "name";

And no luck.

Answer 1

You’re starting by setting up the DataSource on your listbox control, but end up calling DataBind on the dropdown menu.

Try this:

protected void ddlDatabase_SelectedIndexChanged(object sender, EventArgs e)
{
    if (ddlDatabases.SelectedIndex != 0)
    {
        lbxTables.DataSource = Database.GetTables(ddlServers.Text, ddlDatabases.value);
        lbxTables.DataBind();
    }
}

You can also add in the DataValueField and DataTextField on lbxTables there before lbxTables.DataBind();
