这里我要准备一个图表，当我点击btnsearch时clickevent正在触发，但是当我添加updatepanel和Modalpopup扩展器时，这个click事件没有触发 任何帮助都是适当的
protected void btnSearch_Click(object sender, EventArgs e)
{
if ((ddlEmp.SelectedValue != "0") & (dtFrom.Text.Trim() != "") & (dtTo.Text.Trim() != ""))
{
objWork.FK_EmployeeID = Convert.ToDecimal(ddlEmp.SelectedValue);
IFormatProvider provider = new System.Globalization.CultureInfo("en-CA", true);
String datetime = dtFrom.Text.Trim();
DateTime dt = DateTime.Parse(datetime, provider, System.Globalization.DateTimeStyles.NoCurrentDateDefault);
objWork.Fromdate = dt;
provider = new System.Globalization.CultureInfo("en-CA", true);
datetime = dtTo.Text.Trim();
dt = DateTime.Parse(datetime, provider, System.Globalization.DateTimeStyles.NoCurrentDateDefault);
objWork.Todate = dt;
DataTable dtbl = objWork.Chart_ProjectWise_FilterWith_Emp_Date();
// int i = ds.Tables[0].Rows.Count;
ProjectWise.DataSource = dtbl;
ProjectWise.Legends.Add("Percentage").Title = "Work duration of employees";
// here i am giving the title of the x-axis
ProjectWise.ChartAreas["ChartArea1"].AxisX.Title = "Project Name";
// here i am giving the title of the y-axis
ProjectWise.ChartAreas["ChartArea1"].AxisY.Title = "Duration";
// here i am binding the x-axisvalue with the chart control
ProjectWise.Series["Hours"].XValueMember = "ProjectName";
// here i am binding the y-axisvalue with the chart control
ProjectWise.Series["Hours"].YValueMembers = "Duration";
ProjectWise.DataBind();
}
}

请参阅下面的帖子。它说在加载到更新面板中时，asp.net验证脚本无法正确加载。
