Question

我的列表視圖的ItemTemplate如下

<a href='<%# getpath(Eval("IMAGE_PATH")) %>' title='<%# Eval("IMAGE_DESCRIPTION") %>'> 
    <asp:Image ID="capty" CssClass="capty" runat="server" 
     AlternateText='<%# Eval("IMAGE_DESCRIPTION") %>' 
     ImageUrl='<%# retriveurl(Eval("IMAGE_PATH")) %>' 
     Height="100px" Width="150px"> 
    </asp:Image> 
</a> 

我隱藏源

int count=ListView1.Items.Count; 
    List<ImageGallery> _list = new List<ImageGallery>(); 
    for (int i = 0; i < count; i++) 
    { 
     ImageGallery ob = new ImageGallery(); 
     ob.ImageName = ?? 
     ob.Description = ?? 
     _list.Add(ob); 
    } 

現在我要插入的評估和演示（「IMAGE_DESCRIPTION」）數據添加到ob.Description和ob.ImageName = Eval（「IMAGE_ID」）。如何做到這一點？

List<ImageGallery> _list = new List<ImageGallery>(); 
for (int i = 0; i < ListView1.Items.Count; i++) 
{ 
    ImageGallery ob = new ImageGallery(); 
    ob.ImageName = ""; 
    ob.Description = " "; 
    _list.Add(ob); 
}

您可以使用FindControl來獲取圖像。您傳遞您想要查找的控件的ID（「capty」）;它會返回一個對象，因此您需要將其轉換/取出到控制類型Image。見下：

List<ImageGallery> _list = new List<ImageGallery>(); 
for (int i = 0; i < ListView1.Items.Count; i++) 
{ 
    Image image = (Image)ListView1.Items[i].FindControl("capty"); 
    ImageGallery ob = new ImageGallery(); 
    ob.ImageName = ""; 
    ob.Description = image.AlternateText; 
    _list.Add(ob); 
}
