在ASP.NET控件转发复选框图像 [英] Checkbox for images in an ASP.NET repeater controls

问题描述

我与ASP.NET工作。我使用一个中继器来显示图像，我也正在使用的每个图像的复选框。

I am working with ASP.NET. I am using a repeater to display images, and I also am using a check box for each image.

如何选择单个图像和更新它们的值按图片ID？

How can I select individual images and update their values as per image id?

我的code是：

 protected void Button3_Click(object sender, EventArgs e)
        {
            foreach (RepeaterItem ritem in Repeater1.Items)
            {
                CheckBox btn = ritem.FindControl("CheckBox1") as CheckBox;
                if (btn.Checked == true)
                {
                    string chrck = btn.Text;
                }
            }
        }

这在我的控制，我有使用：

This my control which i have use :

    <asp:Repeater ID="Repeater1" runat="server">
         <ItemTemplate>
               <br />
               <img ID="ImageZoom" runat="server" 
                    src='<%# DataBinder.Eval(Container.DataItem, "ImageUrl") %>'  
                    style="display: inline; height:auto; left: 0pt; top: 0pt; 
                    width:auto;" />
                <asp:CheckBox ID="CheckBox1" runat="server" Enabled="True" 
                      Text='<%# DataBinder.Eval(Container.DataItem, "ImageId") %>' 
                      oncheckedchanged="RepeaterCheckBox_CheckedChanged"/> 
          </ItemTemplate>
    </asp:Repeater>
    <br />
    <br />
    <asp:Button ID="Button1" runat="server" onclick="Button3_Click" Text="Pint" />

但在C＃code，我总是让价值器isChecked = FALSE 。即使我选中的复选框，并当我点击的品脱的按钮，我只得到虚假的。我怎样才能解决这个问题？如果我选中该复选框，它应该返回true。

But in c# code, I am always getting IsChecked value = false . Even if I checked Checkbox and also when I click on pint button, I am getting only false . How can I solve this? If I checked the checkbox , it should return true.

推荐答案

尝试的ItemDataBound 和的FindControl

try with ItemDataBound and FindControl

void Repetarer_ItemDataBound(Object Sender, RepeaterItemEventArgs e) 
{
          if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 
          {
               var control = e.Item.FindControl("CheckBox1") as CheckBox;      
               string result = control.Text;
               ..... 
          }
       }
