Question

I have a drop down list populated from a database. When i use the dplTags.SelectedItem.Value it only returns the first value and not the one i selected?

Could Someone tel me where i’m going wrong?

When i call it:

String TagID = dplTags.SelectedItem.Value; // Will only select the first value????

It always returns the TagID of the first item, not the selected one :\

This is how i bind it:

using (var conn = new SqlConnection(Properties.Settings.Default.DBConnectionString))
            {
                conn.Open();

                SqlDataAdapter daTags
                = new SqlDataAdapter("Select * From Tag", conn);

                DataSet dsTags = new DataSet("TagCloud");

                daTags.FillSchema(dsTags, SchemaType.Source, "Tag");
                daTags.Fill(dsTags, "Tag");

                daTags.MissingSchemaAction = MissingSchemaAction.AddWithKey;
                daTags.Fill(dsTags, "Tag");

                DataTable tblTag;
                tblTag = dsTags.Tables["Tag"];

                dplTags.DataSource = dsTags;
                dplTags.DataMember = "Tag"; 
                dplTags.DataValueField = "TagID"; //Value Member
                dplTags.DataTextField = "Value"; // Display Member
                dplTags.DataBind();
            }

Please help, Thanks in Advance.

Where are you binding data to these dropdown list controls? They should be bound only in the initial loading of the page as follows. I suspect that you are binding them in every page load and therefore selected values disappear.

protected void Page_Load(object sender, EventArgs e)
{

    if (!Page.IsPostBack)
    {
        //Please check if you are binding checkbox controls here. 
        //If not bring them in here
    }
}
