Actually there is no Row in GridViewCommandEventArgs, so you will need to get the row from the command source naming container
实际上 GridViewCommandEventArgs 中没有 Row，因此您需要从命令源命名容器中获取该行
GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
then you will be able to use
然后你就可以使用
TextBox myTextBox = row.FindControl("MyTextBoxId") as TextBox;
Hope this helps!
希望这可以帮助！

If u want to find a control in row command Use
如果你想在行命令中找到一个控件使用
controlname controlId=(controlname)e.FindControl("controlId");
For example if u want to find a lablewith Id lblthen use..
例如，如果你想找到一个带有 Id lbl的标签，那么使用..
Label lbl = (Label)e.Row.FindControl("lbl");

GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
Label lblProdId = (Label)row.FindControl(“lblproductId”);

You can use "CommandArgument" in your Control with "CommandName". Here 2 arguments :
您可以在带有“CommandName”的控件中使用“CommandArgument”。这里有2个参数：
<asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" CommandArgument='<%# Container.DataItemIndex + ";" + Eval("idinterlocuteur") %>'>
Then in your code behind you can get arguments :
然后在你后面的代码中你可以得到参数：
string[] arg = e.CommandArgument.ToString().Split(';');
int index = Convert.ToInt16(arg[0]);
string idinterlocuteur = arg[1];
And now you arguments to find your controls :
现在你有理由找到你的控件：
CheckBox Check1 = GridView1.Rows[index].FindControl("MyCheckboxinrow") as CheckBox;

If you are using usercontrols in your gridview itemtemplate then ((Control)e.CommandSource).NamingContainermight not return your gridviewrow.
如果您在 gridview itemtemplate 中使用用户控件，则((Control)e.CommandSource).NamingContainer可能不会返回您的 gridviewrow。
In that case I used the following code for getting the current row:
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;
It's not pretty, but it works.
它不漂亮，但它有效。

if your using LinkButton
如果您使用 LinkButton
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);
HiddenField hdMeasurementId = ((HiddenField)row.FindControl("hdMeasurementId"));
