How to Check ImageURL in DataList


Hi

try this example that we store image name in database and uplaod image in Car_Image folder

Place this function in page code behind:
    Protected Function GetImageUrl(ByVal url As Object) As String
        Dim url1 As String = ""
        If url Is DBNull.Value OrElse String.IsNullOrEmpty(url) Then
            url1 = "~/Car_Image/NOIMAGE.jpg"
        Else
            url1 = String.Format("~/Car_Image/{0}", url)
        End If

        Return ResolveUrl(url1)
    End Function

 
And change the image code to :

<asp: DataList ID="dlCountry" runat="server"  RepeatDirection="Horizontal" >
<ItemTemplate>
<asp:image id="Image1" runat="server" ImageUrl='<%# GetImageUrl(Eval("Image")) %>' />
</ItemTemplate> 
</asp: DataList>

Good Luck
