Question

我正在寻找是否有类似于ASP.Net GridView的DataGrid.SelectedItem的功能。

情况是，在WPF中，单击按钮，我使用DataGrid.Items.Add(class_object)添加一个类对象在WPF DataGrid中，如果我单击任何数据网格行中的按钮，我可以使用以下代码来获取类对象：

DataGrid dg = sender as DataGrid;
MyClass editedrow = (MyClass)dg.SelectedItem;

我的问题是，在ASP.Net gridview中是否有任何这样的功能来添加一个类对象以及在Button上点击检索类对象？

修改

我按照第一条评论中的说法尝试了以下内容：

GridView gv = sender as GridView;
MyClass editedrow = (MyClass)gv.SelectedRow;

显示错误'System.Web.UI.WebControls.GridViewRow' to 'Nubicus.gui.MyClass'

Answer 1

试试这个

GridView gv = sender as GridView;
GridViewRow editedrow = (GridViewRow)gv.SelectedRow;


    <asp:Button ID="btnEdit" runat="server" Text="Edit" OnCommand="dgSODetails_Command"
CommandName="Edit" CommandArgument="<%# ((GridViewRow)Container).RowIndex %>"
OnClick="btnEdit_Click" />


protected void btnEdit_Click(object sender,EventArgs e)
{
        Button btn = (Button)sender;
        GridViewRow row = (GridViewRow)btn.NamingContainer;
        int i = Convert.ToInt32(row.RowIndex);
        string SO_ItemType= row.Cells[1].Text 



}
