搜索特定行时未处理的GridView触发事件RowEditing

Question

我有一个带有2列的网格视图，一列用于文本框，另一列用于编辑图标。 如果单击编辑图标，它将打开文本框进行编辑，第二列将包含更新图标和取消图标。 在gridview上方还有一个搜索文本框，允许用户搜索特定的行。

第一种情况：例如，当我有5行并单击任意行中的编辑图标时，它将打开编辑框，我可以进行编辑。

第二种情况：当我在搜索字段中键入文本并单击搜索按钮时，它将检索相应的行并将其单独显示在网格视图中。

问题是，当我单击该行（搜索结果）的编辑图标时，它显示：GridView引发了未处理的事件RowEditing

这是我的gridview：

<asp:GridView ID="PSGridView" runat="server" AutoGenerateColumns="False" DataKeyNames="StatusID" DataSourceID="PSSqlDataSource" ShowFooter="True" BorderStyle="None" BorderWidth="1px" Width="100%" ShowHeaderWhenEmpty="True" EmptyDataText="No protocal status."

C＃背后的代码：

protected void PSGridView_RowCommand(object sender, GridViewCommandEventArgs e) {
        var exist = 0;            
        if (e.CommandName == "DeletePS" )
        {
            some code
        }

        else if (e.CommandName == "UpdatePS")
        {
            var exist1 = 0;    
            //When update, check if the new name is already exist in the database
            //*******************************************************************
            var index = Convert.ToInt32(e.CommandArgument);

            if (index >= 10)
            {
                index = index % 10;
            }

            var pageSize = PSGridView.PageSize;
            GridViewRow row = PSGridView.Rows[index % pageSize];

只需做一件简单的事情就可以激发gridview的RowEditing事件。

select gridview
go to properties
select events and then double click on row editing and then run the page again.
