【发布时间】：2015-02-05 16:04:26
【问题描述】：

我有一个网格格式的ListView，其中包含标题为 (NAME,ID,ADDRESS,GENDER,MOBILENO,PHOTO,BLOCK)。

BLOCK 列的每一行都包含一个 CheckBox。

当BLOCK列中的复选框被选中时，该复选框的特定行应更改为只读，导致该特定行的背景颜色发生变化。

我在 aspx 中的 listview 编码是...

        </SelectedItemTemplate>

    </asp:ListView>

我的aspx.cs 编码是......

 protected void ListView1_OnItemDataBound(object sender, ListViewItemEventArgs e)
    {
        if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            CheckBox BLOCKCheckBox = (e.Item.FindControl("BLOCKCheckBox") as CheckBox);
            if (BLOCKCheckBox.Checked)
            {

            }
            else
            {

            }

        }
    }

请帮帮我.....

谢谢……

【问题讨论】：

您希望实现的逻辑部分应该通过 JavaScript，而不是 C#，或者使用 Ajax 请求（也包括 JS），或者可能完全重新加载页面（纯 .asp）来完成。我认为您需要阅读有关主题的更多信息。
行的背面颜色变化并不重要，
应该改为只读模式

标签： c# asp.net listview checkbox

【解决方案1】：

为块复选框添加 oncheckedChanged 和 autopostback=true

aspx.cs

 protected void BLOCKCheckBox_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox checkbox = (CheckBox)sender;
        ListViewItem itm = (ListViewItem)checkbox.NamingContainer;
        if (lstview1.EditIndex == itm.DisplayIndex)
        {

            (itm.FindControl("NAMETextBox") as TextBox).ReadOnly = true;
        }
    }
