我有一个将 rowCommand 设置为其中一列的 gridview。一切正常，但我在 gridview 中的每一行都遇到了这个奇怪的错误。RowCommand 块不执行。除最后一行外，所有其他行都有效。如果我对网格视图进行排序并且最后一行位于顶部，则它可以正常工作，但是任何行都位于底部，再次无法正常工作。

和我的服务器端代码
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("zarejdame stranitsata <br />");
//BindServerTime();
// set display preferences
gvSchedules.PageSize = UsersHelper.GetDisplayItemsPerPage();
if (!IsPostBack)
{
chkRecursive.Visible = (PanelSecurity.EffectiveUser.Role != UserRole.User);
// toggle controls
//btnAddItem.Enabled = PackagesHelper.CheckGroupQuotaEnabled(
// PanelSecurity.PackageId, ResourceGroups.Statistics, Quotas.STATS_SITES);
searchBox.AddCriteria("ScheduleName", GetLocalizedString("Text.ScheduleName"));
searchBox.AddCriteria("Username", GetLocalizedString("Text.Username"));
searchBox.AddCriteria("FullName", GetLocalizedString("Text.FullName"));
searchBox.AddCriteria("Email", GetLocalizedString("Text.Email"));
bool isUser = PanelSecurity.SelectedUser.Role == UserRole.User;
gvSchedules.Columns[gvSchedules.Columns.Count - 1].Visible = !isUser;
gvSchedules.Columns[gvSchedules.Columns.Count - 2].Visible = !isUser;
Response.Write("page load za parvi pat<br />");
}
Response.Write("krai na page load<br />");
}
protected void odsSchedules_Selected(object sender, ObjectDataSourceStatusEventArgs e)
{
if (e.Exception != null)
{
ProcessException(e.Exception);
e.ExceptionHandled = true;
}
}
protected void gvSchedules_RowCommand(object sender, GridViewCommandEventArgs e)
{
Response.Write("1111");
Response.Write("aaaa " + e.CommandArgument + "<br />");
int scheduleId = Utils.ParseInt(e.CommandArgument.ToString(), 0);
if (e.CommandName == "start")
{
Response.Write("start schedule<br />");
try
{
int result = ES.Services.Scheduler.StartSchedule(scheduleId);
if (result < 0)
{
ShowResultMessage(result);
return;
}
}
catch (Exception ex)
{
ShowErrorMessage("SCHEDULE_START_TASK", ex);
return;
}
}
else if (e.CommandName == "stop")
{
try
{
int result = ES.Services.Scheduler.StopSchedule(scheduleId);
if (result < 0)
{
ShowResultMessage(result);
return;
}
}
catch (Exception ex)
{
ShowErrorMessage("SCHEDULE_STOP_TASK", ex);
return;
}
}
// rebind grid
gvSchedules.DataBind();
}
我的 PageLoad 中没有任何内容。通过调试，我可以看到输入触发了最后一行的回发，它到达了页面加载，但从未到达 rowCommand 代码块。Response.Write("1111"); 永远不会出现。任何想法都会有所帮助。
