ListView 复选框问题

Question

我有一个网格格式的 ListView，其中包含 headers 作为 (NAME,ID,ADDRESS,GENDER ,MOBILENO,PHOTO,BLOCK).

BLOCK 列每行包含一个 CheckBox。

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

我在 aspx 中的列表视图编码是...

    {
        if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            CheckBox BLOCKCheckBox = (e.Item.FindControl("BLOCKCheckBox") as CheckBox);
            if (BLOCKCheckBox.Checked)
            {

            }
            else
            {

            }

        }
    }

请帮助我......

谢谢....

Answer 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;
        }
    }
