c# - 单击按钮获取行的 DataKeyNames

Question

我有一个 gridview，每行都有按钮:

按钮位于模板字段中:

<asp:GridView ID="storyGridView" runat="server" AllowSorting="True" AutoGenerateColumns="False" 
      BackColor="#DEBA84" BorderColor="#DEBA84" BorderStyle="None" BorderWidth="1px" CellPadding="3"    
      CellSpacing="2" DataKeyNames="PK_NonScrumStory" DataSourceID="SqlDataSource1">
...
        <asp:TemplateField HeaderText="Actions">
            <ItemTemplate>
                <asp:Button ID="viewHoursButton" runat="server" Text="View Hours" OnClick="viewHoursButton_OnClick" />
                <asp:Button ID="addHoursButton" runat="server" Text="Add Hours" OnClick="addHoursButton_OnClick" />
                <asp:Button ID="editButton" runat="server" Text="Edit" OnClick="editButton_OnClick" />
                <asp:Button ID="deleteButton" runat="server" Text="Delete" OnClick="deleteButton_OnClick" />
            </ItemTemplate>
        </asp:TemplateField>

如何在点击时获取数据 key 名称？

protected void viewHoursButton_OnClick(object sender, EventArgs e)
{
    //get PK_NonScrumStory for clicked row
}

Answer 1

我想通了:

protected void viewHoursButton_OnClick(object sender, EventArgs e)
{
    Button btn = sender as Button;
    GridViewRow row = btn.NamingContainer as GridViewRow;
    string pk = storyGridView.DataKeys[row.RowIndex].Values[0].ToString();
    System.Diagnostics.Debug.WriteLine(pk);
}
