Question

I’m doing a project in asp.net using 3-tier architecture. Using various trial and errors i have successfully binded the values inside a column of a table inside the dropdownlist.

The thing that I’m stuck with right now is that during the pageload event i get the values inside the dropdown box that are available in my table. But the real problem is i have to get the first value inside the dropdownlist as “Select” or “Choose any One”. I’m Not able to do this.

Heres my code

        DataTable datatable = new DataTable();
       _bl = new HomeFileUploadBL();
        voo = _bl.SelectNameOfDocument();
        datatable = voo.DocumentName;
        ddlDocument.DataSource = datatable;
        ddlDocument.DataTextField = datatable.Columns["Name"].ToString();
        ddlDocument.DataValueField = datatable.Columns["Name"].ToString();
        ddlDocument.DataBind();

notations are:
ddlDocument refers to DropDownList,
datatable refers to DataTable, _bl refers to the object of business class, voo.Document refers to the value object class,Document is of the type DataTable.

As soon as the page loads the first value from the table is available inside the dropdownlist.

Also when i click on the dropdownlist my first value shoul be “Select” or “Choose any one”

Am im missing that is really obvious. ?

Hi try something like this…

DataRow dtRow = null;  if (ddlDocument.Rows.Count > 0)
    {
        dtRow = ddlDocument.NewRow();
        dtRow[0] = 0;
        dtRow[1] = "Select All";
        ddlDocument.Rows.InsertAt(dtRow, 0);
        ddlDocument.AcceptChanges();

    }
