我在页面中添加了一个全选复选框，并使用JQuery为其编写逻辑：
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.2.min.js">
</script>
<script>
$(document).ready(function () {
var chkAll = $("#<%= chkSelectAll.ClientID %>");
var domCheckbox1 = chkAll[0];
if (typeof domCheckbox1 !== "undefined") { var isChecked = domCheckbox1.checked; }
if (isChecked == true) {
$("#<%= GVAccounts.ClientID %>").find("[type='checkbox']").prop('checked', true);
}
else{
$("#<%= GVAccounts.ClientID %>").find("[type='checkbox']").prop('checked', false);
}
});
</script>
select all code会检查gridview的子网格中的所有复选框（chkSelect在下面的代码中）：
<asp:Label ID="lblSelectAll" runat="server" Text="Select All : "></asp:Label>
<asp:CheckBox ID="chkSelectAll" runat="server" AutoPostBack="true" />

当我单击全选复选框时，它会选择gridview中的复选框，但不会触发gridview中复选框的后端逻辑。逻辑是，当选中一个复选框时，它应该启用gridview中的其他控件，代码如下：
Protected Sub chkSelect_CheckedChanged(sender As Object, e As EventArgs)
For Each row As GridViewRow In GVAccounts.Rows
cmd = New SqlCommand("select submitted, id, effective FROM DmdOD where no = @no and entered = '" & ddDate.SelectedItem.Text & "' order by effective, time_, seqno_dmddmhi_dmhi", conn)
cmd.Parameters.Add(New SqlParameter("@no", row.Cells(1).Text))
Dim strRead As StringReader = New StringReader(Session("xml").ToString)
Dim xml As XmlTextReader = New XmlTextReader(strRead)
Dim gvChild As GridView = DirectCast(row.FindControl("gvChildGrid"), GridView)
For Each childrow As GridViewRow In gvChild.Rows
If chk.Checked Then
childrow.Cells(8).Enabled = True
childrow.Cells(9).Enabled = True
childrow.Cells(10).Enabled = True
childrow.Cells(11).Enabled = True
childrow.Cells(12).Enabled = True
childrow.Cells(13).Enabled = True
LoadXMLFromSession(childrow, hidden)
Else
childrow.Cells(8).Enabled = False
childrow.Cells(9).Enabled = False
childrow.Cells(10).Enabled = False
childrow.Cells(11).Enabled = False
childrow.Cells(12).Enabled = False
childrow.Cells(13).Enabled = False
LoadXMLFromSession(childrow, hidden)
'Clear out values when not selected
ddNoteList.SelectedIndex = 0
ddlNote.SelectedItem.Selected = False
ddlNote.Items.FindByValue("").Selected = True
ddBranchBox.SelectedIndex = 0
txtAccountBox.Text = ""
ddTypeBox.SelectedIndex = 0
txtSubBox.Text = ""
LoadDefaultValues()
WriteXML()
'LoadXMLFromSession(childrow, hidden)
End If
Next
Next
'CheckForSubmit()
End Sub
为了让这个行为正常，我缺少什么？
答案 0 :(得分：0)
chkSelect_CheckedChanged是一个asp.net函数，当你使用jquery选中复选框时，它不会被激发。
如果你想从jquery调用CodeBehind方法，那么你可以使用Ajax和PageMethods：
