Asp GridView make hyperlink column editable - asp.net

Question

I have asp:GridView. I can edit all columns without problems, except this one:
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="hyperlinkEdocs" runat="server" Target="HyperLink"
HeaderText="Dopolnitve (eDocs)"
NavigateUrl='<%# String.Format("http://{0}", Eval("CUSTOMER").ToString()) %>'
Text='<%# Eval("CUSTOMER") %>'></asp:HyperLink>
</ItemTemplate>
I am editing columns by click on 'Edit' link (this triggers that columns content is displayed in a text boxes).
How can I make this column editable, so I will be able to edit and update hyperlink in column?

I'm not 100% sure what you are trying to do because I can't see your code behind but why don't you use an edit item template?

Answer 3

<asp:TemplateField HeaderStyle-Width="100px" HeaderText = "ABC">
<ItemTemplate>
<asp:Label ID="label" runat="server"
Text='<%# Eval("id")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="textbox1" Width="100px" Height="50px" runat="server"
Text='<%# Eval("id")%>'></asp:TextBox>
</EditItemTemplate>
<HeaderStyle Width="80px" HorizontalAlign="Center" VerticalAlign="Middle" />
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
</asp:TemplateField>
Edit link click open textbox
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
grd_view();
}
