推荐答案

在后面的代码中执行此操作。

To do this in the code behind.

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
    If e.CommandName = "check" Then
        'Enable Editing on the GridView
        GridView1.EditIndex = GridView1.SelectedIndex
        'Assign value to the row selected
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        'Assign selected gridview row
        Dim checkBox As CheckBox = GridView1.Rows(index).FindControl("ChkAll")

        checkBox.Checked = true 'or false or whatever based on your command.
    End If
End Sub

如果你想在Javascript中做一个关于CodeProject的好文章



使用Javascript在GridView中检查/打开CheckBox [ ^ ]

首先给出所有同名复选框的类名，然后在所有复选框的oncheckchange事件中调用Jqury / Javascript函数。在你的Jquery / Javascript中。设置检查/取消选中属性。

first you give the class name of all the checkbox of same name then call a Jqury /Javascript function in oncheckchange event of all the checkbox . In your Jquery /Javascript . Set the Check/Uncheck Attribute.
