实际上 GridViewCommandEventArgs 中没有 Row，因此您需要从命令源命名容器中获取行

GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);

那么你就可以使用

TextBox myTextBox = row.FindControl("MyTextBoxId") as TextBox;

希望这可以帮助！

如果您使用 LinkBut​​ton

 LinkButton ctrl = e.CommandSource as LinkButton;
   if (ctrl != null)
    {
        GridViewRow row = ctrl.Parent.NamingContainer as GridViewRow;
        TextBox txtDescription = (TextBox)row.FindControl("txtDescription");
    }

GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);

Label lblProdId = (Label)row.FindControl(“lblproductId”);

如果你想在行命令中找到一个控件使用

controlname controlId=(controlname)e.FindControl("controlId");

例如，如果你想找到一个ID为lbl的标签，那么使用..

Label lbl = (Label)e.Row.FindControl("lbl");

您可以在控件中使用“CommandArgument”和“CommandName”。这里有2个论点：

<asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" CommandArgument='<%# Container.DataItemIndex + ";" + Eval("idinterlocuteur") %>'>

然后在你后面的代码中你可以获得参数：

string[] arg = e.CommandArgument.ToString().Split(';');
int index = Convert.ToInt16(arg[0]);
string idinterlocuteur = arg[1];

现在你争论找到你的控制：

CheckBox Check1 = GridView1.Rows[index].FindControl("MyCheckboxinrow") as CheckBox;

GridViewRow gvr = (GridViewRow)((Control)e.CommandSource).NamingContainer; int rowIndex = gvr.RowIndex;

        string Cat_name = (GridView1.Rows[rowIndex].FindControl("TxtName") as TextBox).Text;

如果您在 gridview 项目模板中使用用户控件，则((Control)e.CommandSource).NamingContainer可能不会返回您的 gridviewrow。

在这种情况下，我使用以下代码获取当前行：

var c = ((Control) e.CommandSource).NamingContainer;
while (c.GetType() != typeof(GridViewRow))
{
    c = c.Parent;
}
var currentRow = (GridViewRow) c;

它不漂亮，但它有效。

 GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);                    
                    HiddenField hdMeasurementId = ((HiddenField)row.FindControl("hdMeasurementId"));

GridViewCommandEventArgs 不支持行，所以使用命名容器来查找控件。

  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       Control ctrl = e.CommandSource as Control;  
       if (ctrl != null)
       {
           GridViewRow gvRow = ctrl.Parent.NamingContainer as GridViewRow; 
           Label slno = (Label)gvRow.FindControl("slno");  // Find Your Control here
           TextBox txtno = (TextBox)gvRow.FindControl("txtno");  // Find Your Control here
           // Your work start here
       }
    }
