hop of those help? How do I set the initial value of a databound drop down list in ASP.NET? , I think what you want to do is this:
code :
<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Text="--Select One--" Value="" />   
</asp:DropDownList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="DropDownList1"></asp:RequiredFieldValidator>

will be helpful for those in need This does not change anything else than the text of the selected item in your DropDownList. Do you want to change the text and value of the project, or do you want to select the project from the DropDownList that relates to the selected row in the grid?
To change the project name and id, you'll have to change it in the data source behind the ProjectList. But if you just want to select the related project, you can use this:
code :
var row = GridView1.SelectedRow;

if (ProjectList.Items.FindByText(row.Cells[2].Text) != null)
{
    ProjectList.ClearSelection();
    ProjectList.Items.FindByText(row.Cells[2].Text).Selected = true;
}

{
    List<SelectListItem> list = new List<SelectListItem>();
    list.Add(new SelectListItem { Text = "Yes", Value = "Y" });
    list.Add(new SelectListItem { Text = "All", Value = "A" });

I think the issue was by ths following ,
The DataItem property is only available during and after the RowDataBound event of a GridView control.
code :
e.NewValues["Type"] = cmbProductTypes.SelectedValue;
