    <p>I've designed a web page in asp.net. And in that page i placed html control too like <code>&lt;a&gt;</code> &amp; <code>&lt;div&gt;</code>. I have written one java script function which is hiding the <code>&lt;div&gt;</code> when i'm clicking on the <code>&lt;a&gt;</code> tag. Its working fine. But when i'm clicking on the asp.net button then page refresh occur again. And it is loading my previous design of the page. I set the <code>display:none</code> of the <code>&lt;div&gt;</code> at the design time. so it is hiding my <code>&lt;div&gt;</code> again when occuring any other server side event. And i don't want let it happen.</p> <p>Javascript function-</p> <pre><code>&lt;script language="javascript" type="text/javascript"&gt; function toggle5(showHideDiv, switchTag) { try { '&lt;%Session["temp"] = "'+more+'"; %&gt;'; var ele = document.getElementById(showHideDiv); var imageEle = document.getElementById(switchTag); if (ele.style.display == "block") { ele.style.display = "none"; imageEle.innerHTML = 'More'; } else { ele.style.display = "block"; imageEle.innerHTML = 'Less'; } } catch (err) { alert("Error"); } } &lt;/script&gt; </code></pre> <p>html code is-</p> <pre><code>&lt;div id="divSearch" style="float:left;height:100%;width:100%;"&gt; &lt;span style="float:right;height:27px;"&gt;&lt;a id="displayText" href="#" onclick="javascript:toggle5('toggleText', 'displayText');"&gt;More&lt;/a&gt;&lt;/span&gt; &lt;/div&gt; &lt;div id="toggleText" style="display:none;height:100%;width:100%;"&gt; &lt;div id="divCalls" style="width:24%;float:left;height:30%;"&gt; &lt;span style="float:left;width:100%;color:#3b5998;"&gt; &lt;asp:CheckBox ID="chkNoCall" runat="server" Text="No call made in " AutoPostBack="True" oncheckedchanged="chkNoCall_CheckedChanged"/&gt; &lt;asp:TextBox ID="txtNoCall" runat="server" Width="12%" Enabled="False"&gt;&lt;/asp:TextBox&gt;&lt;span&gt; days&lt;/span&gt;&lt;/span&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>C#.net code of the Checkbox-</p> <pre><code>protected void chkNoCall_CheckedChanged(object sender, EventArgs e) { if (chkNoCall.Checked == true) { txtNoCall.Enabled = true; } else { txtNoCall.Enabled = false; txtNoCall.Text = ""; } } </code></pre> <p>How to solve this problem?</p> <p>thanks</p>

    1. COSome JS and HTML would be helpful. I'm not sure what you're hiding and handling.

    3. CO@AndersDaniel : It should only execute the button event. Because i want to handle other asp.net events too.

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.
