C# Web App: Setting selected value of drop down list on page load

[dmj07]

Hi all,

I was wondering of an easy way to set the selected value of a drop down list by using a value retrieved from the database. Here is my code:

 
SqlCommand cmdUser = new SqlCommand("SELECT ID FROM Tble WHERE ID = 2", connSQL);
 
        cmdUser.CommandType = CommandType.Text;
 
        SqlDataReader rdrUser = cmdUser.ExecuteReader();
 
        while (rdrUser.Read())
        {
            ddlID.SelectedValue = rdrUser.GetString(0);
        }
        rdrUser.Close();
 
 

On the front end .aspx page the drop down list has a bound data source so I need to set the selected value of this drop down list to the database one.

Many thanks in advance.

Managed to solve this for anybody who may be interested.

New code in OnDataBound function of drop down list.

OnDataBound="dd lID_DataBound"

while (rdrUser.Read())
{
            ddlMaterialType.ClearSelection();
            string test = rdrUser.GetString(0);
            ddlID.Items.FindByValue(test).Selected = true;
}
