Question

在我的gridview中，我添加了一个包含LinkButton的列，允许您删除LinkButton所在行的记录：

<asp:TemplateField HeaderText="">
     <ItemTemplate>
          <asp:LinkButton ID="lnkDeleteTxn" Text="Delete" runat="server" CommandArgument='<%# Eval("TxnID") %>' OnClick="deleteTxn" 
          OnClientClick="return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?');"></asp:LinkButton>
     </ItemTemplate>
</asp:TemplateField>

此LinkButton包括显示一个弹出窗口，询问用户是否确实要删除该记录。现在，对于我的RowDataBound事件，我设置它以便每当记录的状态为“已批准”时，删除LinkButton被禁用：

string recStatus = Convert.ToString(DataBinder.Eval(e.Row.DataItem,"StatusDesc"));
if (recStatus == "Approved")
{
    hlTxnEdit.Enabled = false;
    lnkTxnDelete.Enabled = false;
}
else
{
    hlTxnEdit.Enabled = true;
    lnkTxnDelete.Enabled = true;
    //lnkTxnDelete.Attributes.Add("OnClientClick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");
}

问题是，当用户点击禁用的LinkButton时，确认弹出窗口仍会显示，但不应该，因为LinkButton已被禁用。有一点道理，因为设置弹出窗口的属性位于OnClientClick属性上。如何使弹出窗口不显示？我尝试在后面的代码中添加OnClientClick属性，但它不起作用。 LinkButton直接删除记录。

Answer 1

在aspx中进行更改，如下所示......

<asp:TemplateField HeaderText="">
    <ItemTemplate>
        <asp:LinkButton ID="lnkDeleteTxn" Text="Delete" runat="server" CommandArgument='<%# Eval("TxnID") %>' OnClick="deleteTxn"></asp:LinkButton>
    </ItemTemplate>
</asp:TemplateField>

从后面的代码中添加您的确认弹出窗口。

string recStatus = Convert.ToString(DataBinder.Eval(e.Row.DataItem,"StatusDesc"));
if (recStatus == "Approved")
{
    hlTxnEdit.Enabled = false;
    lnkTxnDelete.Enabled = false;
    lnkTxnDelete.Attributes.Add("onclick", "return false;");
}
else
{
    hlTxnEdit.Enabled = true;
    lnkTxnDelete.Enabled = true;
    lnkTxnDelete.Attributes.Add("onclick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");
}

Answer 2

if (recStatus == "Approved")
 {
    hlTxnEdit.Enabled = false;
    lnkTxnDelete.onClientClick = null;//

 }
 else
  {

    hlTxnEdit.Enabled = true;
    lnkTxnDelete.Enabled = true;
    //lnkTxnDelete.Attributes.Add("OnClientClick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");
  }

Answer 3

您可以在这些步骤中解决问题。

从声明html中删除OnClientClick。

在后面的代码中的GridView OnDataRowBound事件处理程序中添加此OnClientClick

lnkTxnDelete.Attributes.Add("OnClientClick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");

确保仅在recStatus＆lt;＆gt;时添加此代码“已批准”。

Answer 4

而不是在模板字段中定义OnClientClick属性。当状态为Approved时，在RowDataBound事件上添加OnClientClick属性。

lnkButton.Attributes.Add("OnClientClick","Javascript");
