c# - Dropdownlist in edit mode of a gridview -

in application in c#, when edit row in gridview choose new data dropdownlist.

i populating dropdown this:

<asp:templatefield headertext="gender">     <itemtemplate>         <asp:label id="gender" runat="server" text='<%# eval("gender").tostring() %>'></asp:label>     </itemtemplate>     <edititemtemplate>         <asp:dropdownlist id="ddl_genderlist" runat="server">             <asp:listitem value="" text="---"></asp:listitem>             <asp:listitem value="m" text="m"> </asp:listitem>             <asp:listitem value="f" text="f"> </asp:listitem>         </asp:dropdownlist>     </edititemtemplate> </asp:templatefield> 

but when press 'edit' button template , enters in 'rowupdating' event, selected value dropdownlist every time first value dropdownlist.

i need selected value in dropdownlist it's value displays in label gender.

does have ideas?

i've tried many ways set selected value in 'rowdatabound' event, no luck.

i tried this:

protected void gvproducts_rowdatabound(object sender, gridviewroweventargs e) {     datarowview drowview = (datarowview)e.row.dataitem;      if ((e.row.rowstate & datacontrolrowstate.edit) > 0)     {         dropdownlist genderlist = (dropdownlist)e.row.findcontrol("ddl_genderlist");         genderlist.selectedvalue = drowview[1].tostring();     } }
