我需要顯示一個AjaxControlToolkit ModalPopupExtender控件，當用戶選中/取消選中GridView內的CheckBox控件作爲TemplateField時。ASP.NET如何從CheckBox顯示AjaxControlToolkit模式彈出框

在這裏看到最終的解決方案......
我們終於解決了這個問題。所以我決定在這裏發佈完整的解決方案和最終的代碼。
GridView控件
<asp:GridView ID="gvDocs" runat="server" CssClass="grid" AutoGenerateColumns="false" AllowPaging="true" AllowSorting="true"
OnPageIndexChanging="gvDocs_PageIndexChanging"
OnSorting="gvDocs_Sorting"
OnRowDataBound="gvDocs_RowDataBound">
<AlternatingRowStyle CssClass="grid_row_alternate"/>
<HeaderStyle CssClass="grid_header" />
<RowStyle CssClass="grid_row" />
<SelectedRowStyle CssClass="grid_row_selected" />
<Columns>
<asp:BoundField DataField="ID"/>
<asp:BoundField DataField="COLUMN_A" SortExpression="COLUMN_A" HeaderText="COLUMN_A" />
<asp:BoundField DataField="COLUMN_B" SortExpression="COLUMN_B" HeaderText="COLUMN_B" />
<!-- TemplateField with the CheckBox and the ModalPopupExtender controls -->
<asp:TemplateField HeaderText="Check" SortExpression="CHECK_COLUMN">
<ItemStyle HorizontalAlign="Center"/>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server"/>
<!-- Modal Popup block -->
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" BackgroundCssClass="modalBackground" DropShadow="True" TargetControlID="CheckBox1" PopupControlID="panModalPopup" CancelControlID="CancelButton"/>
<asp:Panel ID="panModalPopup" runat="server" style="display:none; text-align:left; width:400px; background-color:White; border-width:2px; border-color:#40A040; border-style:solid; padding:10px;">
Are you sure?
<br /><br />
<div style="text-align:right;">
<asp:Button ID="ConfirmButton" runat="server" Text="Confirm" OnClick="ConfirmButton_Click" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "ID") %>'/>
<asp:Button ID="CancelButton" runat="server" Text="Cancel"/>
</div>
</asp:Panel>
</ItemTemplate>
</asp:TemplateField>
</Columns>
背後
protected void gvDocs_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType.Equals(DataControlRowType.DataRow))
{
// Setting the CheckBox check reading the state from DB
CheckBox CheckBox1 = (CheckBox)e.Row.FindControl("CheckBox1");
CheckBox1.Checked = DataBinder.Eval(e.Row.DataItem, "CHECK_COLUMN").ToString() == "Y"; // Or any other value that works like true/false
}
}
protected void ConfirmButton_Click(object sender, EventArgs e)
{
string id = ((Button)sender).CommandArgument; // Get the ID column value
// Update the CHECK_COLUMN value on the DB or do whatever you want with the ID...
BindData(); // Method that do the GridView DataBind after the changes applied to the DB
}
有些事情的代碼知道
1）ModalPopupExtender1控件位於GridView的TemplateField中，因爲它需要訪問CheckBox1及其單擊事件。這可能不是有史以來最好的解決方案，但它有效，所以如果你的GridView不是太複雜並且是分頁的，它不會影響性能。
2）爲了趕上ConfirmButton點擊事件，你必須從ModalPopupExtender控制設置中刪除OKControlID屬性。

然後我所需要的相應行的ID，以使對數據庫的更新。
- END
這是在GridView
<asp:GridView ID="gvDocs" runat="server" CssClass="grid" AutoGenerateColumns="false" AllowPaging="true" AllowSorting="true"
OnPageIndexChanging="gvDocs_PageIndexChanging"
OnSorting="gvDocs_Sorting"
OnRowDataBound="gvDocs_RowDataBound">
<AlternatingRowStyle CssClass="grid_row_alternate"/>
<HeaderStyle CssClass="grid_header" />
<RowStyle CssClass="grid_row" />
<SelectedRowStyle CssClass="grid_row_selected" />
<Columns>
<asp:BoundField DataField="ID_DOCUMENTO" Visible="False"/>
<asp:BoundField DataField="NUM_PROT" SortExpression="NUM_PROT" HeaderText="N. Prot." />
<asp:BoundField DataField="DATE_PROT" SortExpression="DATE_PROT" HeaderText="Data Prot." />
... some other BoundFields ...
<asp:TemplateField HeaderText="Da archiviare" SortExpression="DA_ARCHIVIARE">
<ItemStyle HorizontalAlign="Center"/>
<ItemTemplate>
<asp:CheckBox ID="chkArchiviare" runat="server" AutoPostBack="True" OnCheckedChanged="chkArchiviare_CheckedChanged"/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
這是ModalPopup塊
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" DropShadow="True" TargetControlID="panModalPopup" PopupControlID="panModalPopup" OkControlID="btnConferma" CancelControlID="btnAnnulla" />
<asp:Panel ID="panModalPopup" runat="server" style="display:none; width:400px; background-color:White; border-width:2px; border-color:Black; border-style:solid; padding:20px;">
Are you sure?
<br /><br />
<div style="text-align:right;">
<asp:Button ID="btnConferma" runat="server" Text="Conferma" OnClick="btnConferma_Click"/>
<asp:Button ID="btnAnnulla" runat="server" Text="Annulla" OnClick="btnAnnulla_Click" />
</div>
</asp:Panel>
現在，我想在每次選中/取消選中複選框時顯示ModalPopup，並且該彈出窗口必須顯示帶有2個按鈕的確認消息：確認並取消。 確認必須對數據庫進行更新，然後回發。 取消只能隱藏彈出而不回發。
我知道ModalPopupExtender偵聽OnClick事件。所以，我是否需要一個Button，LinkButton，ImageButton等，或者我可以做我想做的事情？
噢，真好！我會試一試！謝謝！ –
我把'TargetControlID =「chkArchiviare」'這是我在GridView上的CheckBox控件的名稱，但我得到AjaxControlToolkit的運行時錯誤，它說：「ModalPopupExtender1的TargetControlID無效。無法找到ID = chkArchiviare的控件」 。有任何想法嗎？ –
你需要把modalpopup和panel放到gridview項目模板中，我確定 – AGuyCalledGerald
