Merhaba arkadaşlar bu makalemizde GridView nesnesine dinamik olarak resim ve string girişi yapacağız.
Şimdi projemize 3 adet TextBox, 1 adet FileuPload ve GridView ekleyelim. Resim uzantılarını images klasöründeki ekleyeceğimiz image lardan alacağız.
<Columns>
<asp:ImageField DataImageUrlField="PictureExtension" DataImageUrlFormatString="~\images\{0}" ControlStyle-Height="120" ControlStyle-Width="120" />
</Columns>
