Public Sub ResetControl(ByVal mypage As Page)
       Dim myForm As Control = mypage.FindControl("Form")
       For Each ctrl As Control In myForm.Controls
           'Clears TextBox
           If TypeOf ctrl Is System.Web.UI.WebControls.TextBox Then
               TryCast(ctrl, TextBox).Text = String.Empty
           End If


           'Clears DropDown Selection
           If TypeOf ctrl Is System.Web.UI.WebControls.DropDownList Then
               TryCast(ctrl, DropDownList).ClearSelection()
           End If


           'Clears ListBox Selection
           If TypeOf ctrl Is System.Web.UI.WebControls.ListBox Then
               TryCast(ctrl, ListBox).ClearSelection()
           End If


           'Clears CheckBox Selection
           If TypeOf ctrl Is System.Web.UI.WebControls.CheckBox Then
               TryCast(ctrl, CheckBox).Checked = False
           End If


           'Clears RadioButton Selection


           If TypeOf ctrl Is System.Web.UI.WebControls.RadioButtonList Then
               TryCast(ctrl, RadioButtonList).ClearSelection()
           End If


           'Clears CheckBox Selection
           If TypeOf ctrl Is System.Web.UI.WebControls.CheckBoxList Then
               TryCast(ctrl, CheckBoxList).ClearSelection()
           End If


           If TypeOf ctrl Is System.Web.UI.WebControls.GridView Then
               TryCast(ctrl, GridView).Columns.Clear()
           End If

       Next




   End Sub

我曾经在按钮单击模式下调用以下代码.但是我遇到了错误.请指教

受保护的Sub btnSaveReq_Click(ByVal发送者作为对象，ByVal e作为System.EventArgs)处理btnSaveReq.Click

ResetControl()

end sub

i used to call the below code in button click mode. but i am getting error. please advice

Protected Sub btnSaveReq_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSaveReq.Click

ResetControl()

end sub

推荐答案

Protected Sub btnSaveReq_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSaveReq.Click

' TODO: Add your save code here



ResetControl(Me.Page)

end sub
