Hi Friends,

C#

SqlCommand cmd = new SqlCommand("select ID from login order by ID",con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DropDownList1.DataSource = ds;
DropDownList1.Items.Insert(0, "--Select One--");
DropDownList1.DataTextField = "id";                
DropDownList1.DataBind();

In this, I am not able set the DropDown value to 0 i.e.,"--Select One--"

Please check following snapshot...

Please check the answer Answer to - “DropDownList.SelectedIndex = -1” problem
[^]
Where it says to insert that value after the dropdown is bound...
In your codes do like below...

C#

SqlCommand cmd = new SqlCommand("select ID from login order by ID",con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DropDownList1.DataSource = ds;
DropDownList1.DataTextField = "id";                
DropDownList1.DataBind();

DropDownList1.Items.Insert(0, new ListItem("--Select One--", ""));

Try using this and let me know...

Thanks...

You should use AppendDataBoundItems property. Note the correct Code snippets.

C#

SqlCommand cmd = new SqlCommand("select ID from login order by ID", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DropDownList1.AppendDataBoundItems = true;
DropDownList1.Items.Insert(0, new ListItem("--Select One--", "0"));        
DropDownList1.DataSource = ds;        
DropDownList1.DataTextField = "id";
DropDownList1.DataBind();
