C＃代码

protected void OnRowCommand(object sender,GridViewCommandEventArgs e)
    {
        if(e.CommandName=="Choose")
        {
            GridViewRow row = ((e.CommandSource as LinkButton).NamingContainer as GridViewRow);
            TextBox2.Text = row.Cells[2].Text;
            TextBox3.Text = row.Cells[3].Text;
            TextBox4.Text = row.Cells[4].Text;
        }
    }

尝试此代码。问题在CommandName，因为您没有在LinkButton中提供CommandName

 <asp:TemplateField HeaderText="Update">
          <ItemTemplate>
              <asp:LinkButton ID="link" runat="server" Text="Choose" CssClass="linkbutton" CommandName="Choose"></asp:LinkButton>
          </ItemTemplate>
   </asp:TemplateField>

在ASP.Net中的GridView外部的TextBox中显示GridView Selected Row数据
