hi all,
i have a grid view which include a drop down list, when every time i pull out data from database, i want to assign the value to that dropdownlist.

i like to do something like this:
if(ds.Tables[0].Rows[0].ItemArray[1].ToString() != "")
      ddlRvStatus.selectedValue = ds.Tables[0].Rows[0].ItemArray[1].ToString() ;

how to do that?
<asp:GridView ID="gvReview" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" OnRowDataBound="gvReview_RowDataBound">
                <HeaderStyle CssClass=data_title />
                                        <asp:TemplateField HeaderText="Review Status">
                            <asp:DropDownList ID="ddlRvStatus" runat="server" CssClass="field_item_width">
                            <asp:ListItem Value="Complete">Complete</asp:ListItem>
                            <asp:ListItem Value="Escalated">Escalated</asp:ListItem>
                            <asp:ListItem Value="Incomplete">Incomplete</asp:ListItem>
In .cs file:
DataSet dsReview = new DataSet();
gvReview.DataSource = ds;
gvReview.DataBind(); // when bind the dataSet, i want to assign selected value(which is in dataset) to that dropdroplist, how to do that?

In the gridView_RowDataBound Event
u'll have to find the ddl using findcontrol

protected void gvStationery_RowDataBound(object sender, GridViewRowEventArgs e)
            if (e.Row.RowType == DataControlRowType.DataRow)
                    DropDownList ddlRvStatus = e.Row.FindCOntrol("ddlRvStatus") as DropDownList;
ddlRvStatus.Items.FindByValue(ds.Tables[0].Rows[0].ItemArray[1].ToString()).Selected = true;

Just assign or get the value of the cell, as if it was a "text" cell.
.NET, knowing is a comboBox (or dropDownList) will assign the value to its content (in this case, the combo)
