    <p>Well, I have a situation where I need to provide a slidetoggle effect for my gridview's dynamically generated rows. I use a javascript + pagemethod to achieve the auto generation.</p> <p>This is my ItemTemplate for the gridview</p> <pre><code> &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;a href="javascript:void"&gt; &lt;asp:Image ID="imgExpandCollapse" runat="server" ImageUrl="~/Images/expand.png" onclick='ShowDetails(this);' ToolTip="Toggle"/&gt;&lt;/a&gt; &lt;asp:Label ID="lblUID" Style="display: none" runat="server" Text='&lt;%# Eval("UID") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; </code></pre> <p>I use the following javascript to generate the rows dynamically by calling a web method.</p> <pre><code>function ShowDetails(ImgObj) { if (ImgObj.src.toLowerCase().indexOf("expand") != -1) { if (document.getElementById(ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")) != null) { document.getElementById(ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")).style.display = ""; } else { var newTr = document.createElement("tr"); newTd = document.createElement("td"); var UID = document.getElementById(ImgObj.id.replace("imgExpandCollapse", "lblUID")).innerHTML; newTd.setAttribute("id", ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")); newTd.setAttribute("colspan", "7"); newTd.setAttribute("Style", "padding:0 0 0 0"); newTd.innerHTML = "&lt;div class='centerAlign'&gt;&lt;img src='../Images/loading.gif'/&gt;&lt;/div&gt;"; PageMethods.GetLogResult(UID, OnSucceeded, OnFailed,newTd); newTr.appendChild(newTd); jQuery('#' + ImgObj.id.replace("imgExpandCollapse", "grdRow")).after(newTr); } ImgObj.src = "../Images/collapse.png"; } else { if (document.getElementById(ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")) != null) { document.getElementById(ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")).style.display = "none"; } ImgObj.src = "../Images/expand.png"; } } function OnSucceeded(result, newTd) { newTd.innerHTML = result; } function OnFailed(error) { alert(error.id); } </code></pre> <p>Now the issue of using a Slidetoggle() is that these rows are autogenerated and they have different IDs. Now if somebody could help me out with this, I would be grateful. Thanks.</p> <p>EDIT: Apparently, I was trying to "slide" a table row, which aint supported for slidetoggle in Jquery. I changed the code and it worked :)</p> <pre><code>function ShowDetails(ImgObj) { if (ImgObj.src.toLowerCase().indexOf("expand") != -1) { if (document.getElementById(ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")) != null) { $("#" + ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")).slideToggle(); } else { var newTr = document.createElement("tr"); newTd = document.createElement("td"); newDiv = document.createElement("div"); var UID = document.getElementById(ImgObj.id.replace("imgExpandCollapse", "lblUID")).innerHTML; newTd.setAttribute("colspan", "7"); newTd.setAttribute("Style", "padding:0 0 0 0"); newDiv.setAttribute("id", ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")); newDiv.setAttribute("style", "text-align:center"); newDiv.innerHTML = "&lt;img src='../Images/loading.gif'/&gt;"; PageMethods.GetLogResult(UID, OnSucceeded, OnFailed, newDiv); newTd.appendChild(newDiv); newTr.appendChild(newTd); jQuery('#' + ImgObj.id.replace("imgExpandCollapse", "grdRow")).after(newTr); $("#" + newDiv.id).show(); } ImgObj.src = "../Images/collapse.png"; } else { if (document.getElementById(ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")) != null) { $("#" + ImgObj.id.replace("imgExpandCollapse", "grdRowDetails")).slideToggle(); } ImgObj.src = "../Images/expand.png"; } } function OnSucceeded(result, newDiv) { newDiv.innerHTML = result; } function OnFailed(error) { alert(error.id); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
