    text
    copied!<p>I have problem with positioning ModalPopupExtender in the center of the screen when it's PopupDragHandleControlID property is set (without this property it works fine ).</p> <p>ModalPopupExtender is not positioned in the center of the screen. I thinks what causes the problem is the page's CSS layout cause when i disable it, popup positioned in the center of the screen (I don't understand why page's css affects ModalPopupExtender only when it's PopupDragHandleControlID property is set )</p> <p>Thepage:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;Untitled Page&lt;/title&gt; &lt;link href="layout.css" rel="stylesheet" type="text/css" /&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div&gt; &lt;div id="header"&gt; &lt;/div&gt; &lt;div id="container"&gt; &lt;div id="center" class="column"&gt; &lt;div id="centercolcontent" class="centercolcontent"&gt; &lt;asp:ScriptManager ID="ScriptManager1" runat="server"&gt; &lt;/asp:ScriptManager&gt; &lt;asp:UpdatePanel ID="UpdatePanel1" runat="server" &gt; &lt;ContentTemplate&gt; &lt;asp:Button ID="btnShowPopup" runat="server" Text="Open" /&gt; &lt;asp:Panel ID="pnlUploader" runat="server" CssClass="pnlUploader" style="display: none;"&gt; &lt;cc1:ModalPopupExtender ID="mdlPopup1" runat="server" TargetControlID="btnShowPopup" PopupControlID="pnlUploader" CancelControlID="btnCancel" BackgroundCssClass="modalBackground" PopupDragHandleControlID="pnlUploader" RepositionMode="RepositionOnWindowResize" /&gt; &lt;div id="pnlDragMe" class="pnlDragMe"&gt; Image Uploader &lt;/div&gt; &lt;div class="upload" id="upload"&gt; &lt;div id="status" class="info"&gt; Please select a file to upload &lt;/div&gt; &lt;div class="commands"&gt; &lt;asp:Button ID="btnUpload" runat="server" Text="Upload" OnClientClick="javascript:onUploadClick()" /&gt; &lt;asp:Button ID="btnCancel" runat="server" Text="Cancel" /&gt; &lt;/div&gt; &lt;/div&gt; &lt;/asp:Panel&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;div id="left" class="column"&gt; &lt;/div&gt; &lt;div id="right" class="column"&gt; &lt;/div&gt; &lt;div id="footer"&gt; &lt;/div&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>The CSS:</p> <pre><code>body { min-width: 630px; } #container { padding-left: 200px; padding-right: 150px; } #container .column { position: relative; float: left; } #center { padding: 0px 0px; width: 100%; } #left { width: 200px; padding: 0 0px 0 0; right: 200px; margin-left: -100%; } #right { width: 130px; padding: 0 10px; margin-right: -100%; } #footer { clear: both; } * html #left { left: 150px; /* RC fullwidth */ } /*** Equal-height Columns ***/ #container { overflow: hidden; } #container .column { padding-bottom: 1001em; /* X + padding-bottom */ margin-bottom: -1000em; /* X */ } * html body { overflow: hidden; } * html #footer-wrapper { float: left; position: relative; width: 100%; padding-bottom: 10010px; margin-bottom: -10000px; background: #FFF; /*** Same as body background ***/ } body { margin: 0; padding: 0; } #header, #footer { font-size: large; text-align: center; padding: 0.3em 0; } #left { /*background: #66F;*/ } #center { background: #DDD; } .modalBackground { background-color: Gray; filter: alpha(opacity=70); opacity: 0.7; } </code></pre>
