문제 설명
asp.net gridview ‑ updatepanel을 사용하여 행당 여러 줄에 바인딩된 데이터 분산 (asp.net gridview ‑ spread bound data across multi lines per row with updatepanel)
그리드뷰 내부에 패널이 있고 행 너비에 대해 '확산'되어야 합니다.
패널에 무엇이 있는지 신경쓰지 마십시오. 내가 여기에 보여 주는 것은 단지 내 요구 사항을 시연하기 위한 것입니다...My HTML:
6<asp:GridView ID="GridView1" runat="server"
AutoGenerateColumns="False"
CellPadding="3"
CssClass="myGrid"
DataKeyNames="Role_Name">
<AlternatingRowStyle BackColor="#E6E6E6" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton ID="imgShow" runat="server" OnClick="Show_Hide_details" BorderStyle="None" BackColor="Transparent" ImageUrl="~/Content/Images/Arrow_Down.png"
CommandArgument="Show" />
<asp:Panel ID="pnlRole" runat="server" Style="position: relative;" Visible="false">
<asp:Label ID="lblAAA" runat="server" Text="aaa" /><br />
<asp:Label ID="lblBBB" runat="server" Text="bbb" /><br />
<asp:Label ID="lblCCC" runat="server" Text="ccc" /><br />
<asp:Label ID="lblDDD" runat="server" Text="ddd" /><br />
</asp:Panel>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Role_Name" HeaderText="Name">
<HeaderStyle Width="100px" />
<ItemStyle CssClass="myGridItemMaxWidth" HorizontalAlign="Left" Wrap="false" />
</asp:BoundField>
<asp:BoundField DataField="Role_Description" HeaderText="Description">
<HeaderStyle Width="150px" />
<ItemStyle CssClass="myGridItemMaxWidth" HorizontalAlign="Left" Wrap="false" />
</asp:BoundField>
</Columns>
<HeaderStyle CssClass="myGridHeader" />
<RowStyle ForeColor="#000066" />
</asp:GridView>
어떤 도움/아이디어/해결책을 주시면 감사하겠습니다.
편집: 내 문제를 더 잘 설명하기 위해 여기에 다른 이미지가 있습니다. 
<tr id="pnlRole" runat="server" Visible="false">
<td colspan="3">
<asp:Label ID="lblAAA" runat="server" Text="aaa" /><br />
<asp:Label ID="lblBBB" runat="server" Text="bbb" /><br />
<asp:Label ID="lblCCC" runat="server" Text="ccc" /><br />
<asp:Label ID="lblDDD" runat="server" Text="ddd" /><br />
</td>
</tr>
Now in the code‑behind you can reference this
protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.CommandName == "Toggle")
{
HtmlTableRow pnlRole = e.Item.FindControl("pnlRole") as HtmlTableRow;
pnlRole.Visible = !pnlRole.Visible;
ImageButton imgShow = e.Item.FindControl("imgShow") as ImageButton;
if (pnlRole.Visible == true)
imgShow.ImageUrl="~/Content/Images/Arrow_Down.png";
else
imgShow.ImageUrl="~/Content/Images/Arrow_Up.png";
}
}
방법 2:
Here is what I came up with ‑
On the left is the GridView when all rows are 'closed'. On the right, after 'opening' 2 rows:
Markup:

<RowStyle BackColor="#b5c7de" />
<AlternatingRowStyle BackColor="#d1e0e0" />

I still have lots of formatting and cosmetic issues but for those I'll open a new post. Hope it helps someone.
