Question

我正在尝试确认消息，同时点击删除删除按钮 GridView 。如果我符合，则只会在 GridView 中删除该行。

* .ASPX

<Columns> <asp:CommandField ButtonType="Button" ShowDeleteButton="true" /> </Columns>

* .ASPX.CS

protected void grdPersTable_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { Button buttonCommandField = e.Row.Cells[0].Controls[0] as Button; buttonCommandField.Attributes["onClick"] = string.Format("return confirm('Are you want delete ')"); } } protected void grdPersTable_RowDeleting(object sender, GridViewDeleteEventArgs e) { Label lbl0 = (Label)grdPersTable.Rows[e.RowIndex].FindControl("lblId"); txtId.Text = lbl0.Text; obj.DeleteV(Convert.ToInt32(txtId.Text)); grdPersTable.DataSource = obj.GetTableValues(); grdPersTable.DataBind(); lblMessage.Text = "Deleted successfully !"; }

Answer 1

我得到了回答朋友

<asp:TemplateField>
      <ItemTemplate>
            <asp:Button ID="deletebtn" runat="server" CommandName="Delete" 
             Text="Delete" OnClientClick="return confirm('Are you sure?');" />
      </ItemTemplate>
</asp:TemplateField>

我将 CommandField 更改为 TemplateField

谢谢！

Answer 2

更改rowdatabound事件，如下所示。

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        ((Button)e.Row.Cells[0].Controls[0]).OnClientClick = "return confirm('Are you sure you want to delete?');"; 
    }
}

Answer 3

只需在onclientclick事件上调用javascript函数并要求确认。如果返回true，则可以调用服务器端代码进行删除。

以下是解释代码

<asp:LinkButton ID="lbDelete" runat="server" OnClick="lbDelete_Click" OnClientClick="return fnConfirm();"> Delete</asp:LinkButton>

以下是javascript函数：

<script type="text/javascript">
function fnConfirm() {
    if (confirm("The item will be deleted. Are you sure want to continue?") == true)
        return true;
    else
        return false;
}
</script>

Microsoft 的文档显示了如何使用 ASP 数据源的 DeleteCommand 参数执行此操作的示例：

https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.webcontrols.sqldatasource.deletecommand?view=netframework-4.8

它使用 DataSource 类的“OnDeleting”参数和事件。

删除CommandField中的确认消息？
