Question: How can I insert items into a listbox from a database?
Here is what I tried:
public void Fetch()
{
using (SqlConnection cn = new SqlConnection(UtilObj.ConnectionString()))
{
cn.Open();
ExecuteFetch(cn);
cn.Close();
}
}
public void ExecuteFetch(SqlConnection cn)
{
using (SqlCommand cm = cn.CreateCommand())
{
cm.CommandType = CommandType.StoredProcedure;
cm.CommandText = "spName";
cm.Parameters.AddWithValue("@Param1", Param1Val);
using (SafeDataReader dr = new SafeDataReader(cm.ExecuteReader()))
{
while (dr.Read())
{
myListBox.Items.Add(dr["Color"].ToString());
}
}
}
}
This shows an empty list when I run the code even though it populates in debugger.
ASPX Page
<asp:ListBox ID="myListBox" runat="server" />
I think you're looking for something like this:-
Get reader object after executing your sp
SqlDataReader reader = cmd.ExecuteReader();
myListBox.DataSource= reader; //reader object
myListBox.DataTextField = "Color"; // the field you want to show in listbox
myListBox.DataValueField = "Color"; // the value filed behind the items.
myListBox.Databind();
Text and Value Fields can be same as well if you want it that way
That's it. It's the same way you bind items to a dropdown list. Just used this in our recent project
Hope it's helpful
