Hi all,
I have to bind items from database to the dropdown list with ID as the value and Name as Text. But I want 'select' item in the zeroth positon. I'm using the following code:

C#

SqlDataAdapter da1 = new SqlDataAdapter(strng, con);
DataTable dt = new DataTable();
da1.Fill(dt);
ddLogo.DataSource = dt;
//ddLogo.DataBind();
ddLogo.DataTextField = "Ename";
ddLogo.DataValueField = "ID";
ddLogo.SelectedIndex = -1;
ddLogo.DataBind();
ddLogo.Items.Insert(0, new ListItem("--select--", "--select--"));

But when I'm adding the line
ddLogo.Items.Insert(0, new ListItem("--select--", "--select--"));
only the zeroth position is there in the list.
What I've to do.

Thank you

try ddLogo.Items.Insert(0, new ListItem("--select--", "--select--")); ddLogo.DataBind(); instead and see what happens.

Insert into your data table dont go for fresh insert. Do this after fetch from db

C#

SqlDataAdapter da1 = new SqlDataAdapter(strng, con);
DataTable dt = new DataTable();
da1.Fill(dt);

// generate the data you want to insert
DataRow toInsert = dt.NewRow();

// Then add the new row to the collection.
row["EName"] = "--Select--";
row["ID"] = "--Select--";

// insert in the desired place
dt.Rows.InsertAt(toInsert, 0);
ddLogo.DataSource = dt;
ddLogo.DataTextField = "Ename";
ddLogo.DataValueField = "ID";
ddLogo.DataBind();

Solution 1

You could use AppendDataBoundItems[^] property: set it to true, add your items (you could even do it in markup), then set DataSource and call DataBind()
