C# 调用RowCommand"；选择"；在GridView上以编程方式

我的目标是根据请求参数在gridview中选择一行打开FormView

首先，我在页面加载中获取参数：

基于此，我希望在GridView中获得相应的行（称为gvPrincipal）并选择它：

问题2：在GridView中，页面索引按预期更新，但行（应该是彩色的）没有更新

此外，每行上都有一个ImageButton：

FormView数据源使用gvPrincipalValue更新：

不幸的是什么也没发生

行未保持未选中状态是我最关心的问题，如何克服此问题？

以下是在C中手动调用rowCommand的方法#

MyGridView_RowCommand（MyGridView，新GridViewCommandEventArgs（imgButton，新CommandEventArgs（imgButton.CommandName，imgButton.CommandArgument））

MyGridView是一个GridView。 imgButton是位于MyGridView中的特定GridViewRow中的ImageButton，我正在调用它的row命令。我正在对同样位于MyGridView中的复选框调用此RowCommand，但复选框通常不能作为row命令中的图像按钮处理

    protected void MyCheckBoxInGrid_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chk = sender as CheckBox;

        GridViewRow row = ((GridViewRow)chk.NamingContainer);



        if (chk.Checked)
        {


            ImageButton imgButton = row.FindControl("ImgDetail") as ImageButton;
            MyGridView_RowCommand(MyGridView, new GridViewCommandEventArgs(imgButton , new CommandEventArgs(imgButton .CommandName, imgButton .CommandArgument)));
        }}
