无法运行gridview.databind（），EventArgs的错误 [英] Unable to run gridview.databind(), eventargs error

问题描述

我有一个列表框，在选定的变化，运行速度将数据绑定到一个GridView的方法。我得到的错误：无法投类型的对象System.EventArgs为键入'System.Web.UI.WebControls.GridViewRowEventArgs。我有打电话从其他控制另一gridview.databind（）我的code的其他部分，所以我不知道为什么它现在抛出这个错误？

 保护小组lstEmployees_SelectedIndexChanged（BYVAL发件人为对象，BYVAL E上EventArgs的）把手lstEmployees.SelectedIndexChanged
    暗淡x As中的Int16
    暗淡startStr，endStr作为字符串    如果txtAdminSelectedDate.Text＆LT;＆GT;  然后
        dtWeeks = GetWeek（txtAdminSelectedDate.Text）
    万一    如果dtWeeks.Rows.Count＆GT; 0，则
        X = dtWeeks.Rows（0）.Item（0）的ToString（）的IndexOf。（ - ）
        endStr = dtWeeks.Rows（0）.Item（0）的ToString（）子串（X + 1，11）
        startStr = dtWeeks.Rows（0）.Item（1）的ToString（）
        dtWrkHours = GetHoursOfTheWeek（startStr，endStr，_user）.Tables（0）
        gvAdmin.DataSource = dtWrkHours
        gvAdmin.DataBind（）
        sStatus =的String.Empty
        aStatus =的String.Empty
        AdminTot = 0
        timeTot = 0
    万一结束小组
 

解决方案

我忘了我问这个问题，但删除的RowDataBound并重新创建它固定它。我知道这是一个很奇怪的。

I have a listbox, that on selected change, runs a method to bind data to a gridview. I get the error: Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.GridViewRowEventArgs'. I have other parts of my code that call another gridview.databind() from other controls, so I have no idea why it's throwing this error now?

Protected Sub lstEmployees_SelectedIndexChanged(ByVal sender As Object, ByVal e As     EventArgs) Handles lstEmployees.SelectedIndexChanged
    Dim x As Int16
    Dim startStr, endStr As String

    If txtAdminSelectedDate.Text <> "" Then
        dtWeeks = GetWeek(txtAdminSelectedDate.Text)
    End If

    If dtWeeks.Rows.Count > 0 Then
        x = dtWeeks.Rows(0).Item(0).ToString().IndexOf("-")
        endStr = dtWeeks.Rows(0).Item(0).ToString().Substring(x + 1, 11)
        startStr = dtWeeks.Rows(0).Item(1).ToString()
        dtWrkHours = GetHoursOfTheWeek(startStr, endStr, _user).Tables(0)
        gvAdmin.DataSource = dtWrkHours
        gvAdmin.DataBind()
        sStatus = String.Empty
        aStatus = String.Empty
        AdminTot = 0
        timeTot = 0
    End If

End Sub

解决方案

I forgot I asked this questions, but deleting RowDatabound and re-creating it fixed it. I knew it was something weird.
