  1. POTwo placeholders inside modal popup
    text
    copied!<p>I have a modal popup extender. Inside the panel I have two placeholders. Both are visible false. When I press a button and have code like <code>this.ModalPopupExtender1.Show(); PlaceHolder1.Visible = true; PlaceHolder2.Visible = false;</code> The modal popup opens. When I have code like this:</p> <pre><code>this.ModalPopupExtender1.Show(); PlaceHolder1.Visible = false; PlaceHolder2.Visible = true; </code></pre> <p>The modal popup doesn’t open. How can solve this issue? I attach my asp.net code:</p> <pre><code>&lt;asp:Button ID="btnShowPopup" runat="server" style="display:none" /&gt; &lt;asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="pnlpopup" TargetControlID="btnShowPopup" CancelControlID="btnCancel" OkControlID="btnUpdate" BehaviorID="ModalPopupExtender1" DropShadow="true" BackgroundCssClass="modalBackground"&gt; &lt;/asp:ModalPopupExtender&gt; &lt;asp:Panel ID="pnlpopup" runat="server" BackColor="LightGray" CssClass="modalPopup" Width="600px" Height="450px"&gt; &lt;asp:PlaceHolder ID="PlaceHolder1" Visible="false" runat="server"&gt; &lt;table class="style1"&gt; &lt;tr&gt; &lt;td&gt; &amp;nbsp;&lt;/td&gt; &lt;td&gt; &amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; Name:&lt;/td&gt; &lt;td&gt; &lt;asp:TextBox ID="txtName" runat="server" CssClass="textEntry"&gt;&lt;/asp:TextBox&gt; &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtThoughtName" ErrorMessage="*" ValidationGroup="r"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; Description:&lt;/td&gt; &lt;td&gt; &lt;asp:TextBox ID="txtDescription" TextMode="MultiLine" Columns="37" Rows="5" runat="server" CssClass="textEntry"&gt;&lt;/asp:TextBox&gt; &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="*" ControlToValidate="txtDescription" ValidationGroup="r"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; Date:&lt;/td&gt; &lt;td&gt; &lt;asp:TextBox ID="txtDate" runat="server" Width="150px"&gt;&lt;/asp:TextBox&gt; &lt;asp:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="txtDate"&gt; &lt;/asp:CalendarExtender&gt;&lt;asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ErrorMessage="*" ControlToValidate="txtDate" ValidationGroup="r"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;/td&gt; &lt;/tr&gt; &lt;td&gt; &amp;nbsp;&lt;/td&gt; &lt;td&gt; &amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td colspan="2"&gt; &lt;asp:Button ID="btnUpdate" runat="server" CommandName="Update" OnClick="btnUpdate_Click" Text="Create" ValidationGroup="r" Width="100px" /&gt;&amp;nbsp;&amp;nbsp; &lt;asp:Button ID="btnCancel" runat="server" onclick="btnCancel_Click" Text="Cancel" Width="100px" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/asp:PlaceHolder&gt; &lt;asp:PlaceHolder ID="PlaceHolder2" Visible="false" runat="server"&gt; &lt;table class="style1"&gt; &lt;tr&gt; &lt;td class="style6"&gt; Join a Group:&lt;/td&gt; &lt;td&gt; &lt;asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource3" DataTextField="GroupName" DataValueField="GroupId"&gt; &lt;/asp:DropDownList&gt; &amp;nbsp; &lt;asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click"&gt;Create a Group&lt;/asp:LinkButton&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="style6"&gt; &amp;nbsp;&lt;/td&gt; &lt;td&gt; &lt;asp:Button ID="btnUpdate3" runat="server" CommandName="Update" Width="160px" OnClick="btnUpdate2_Click" Text="Join Group" ValidationGroup="a" /&gt; &amp;nbsp; &lt;asp:Button ID="btnCancel3" runat="server" onclick="btnCancel2_Click" Width="160px" Text="Cancel" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="style6"&gt; &lt;asp:Label ID="Label3" Visible="false" runat="server" Text="Group Name:"&gt;&lt;/asp:Label&gt; &lt;/td&gt; &lt;td&gt; &lt;asp:TextBox ID="txtgroupname" Visible="false" CssClass="textEntry" runat="server"&gt;&lt;/asp:TextBox&gt;&lt;asp:RequiredFieldValidator ID="RequiredFieldValidator3" ControlToValidate="txtgroupname" ValidationGroup="z" runat="server" ErrorMessage="*"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="style6"&gt; &amp;nbsp;&lt;/td&gt; &lt;td&gt; &lt;asp:Button ID="Button2" Visible="false" ValidationGroup="z" runat="server" Width="160px" Text="Create New Group" onclick="Button2_Click" /&gt; &amp;nbsp; &lt;asp:Button ID="Button3" Visible="false" runat="server" Width="160px" Text="Cancel" onclick="Button3_Click" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre>
