    copied!<p>adding onclick event to input element (type=image) in large html table (around 2000 rows) causes the page to render slow (in IE 9). the input element appears once for each row. if i remove the onclick it renders fast. onclick calls a javascript function. is there an alternate way to attach the event that would not slow down rendering? javascrpt function is in a .js file that is included in the head and it makes an ajax call to a different page to load a div and display it as a popup dialog (jquery-ui dialog).</p> <pre><code>&lt;table class="tables_wrapper" style="width: 1450px; table-layout:fixed"&gt; &lt;colgroup&gt; &lt;col style="width: 150px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 150px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 150px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 150px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 150px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 30px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 30px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 30px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 100px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 150px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 30px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 30px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 100px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 100px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;col style="width: 100px; word-wrap:break-word; word-break: break-all; " /&gt; &lt;/colgroup&gt; &lt;asp:Repeater runat="server" EnableViewState="false" ID="repeater1"&gt; &lt;ItemTemplate&gt; &lt;tr&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name1%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name2%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name3%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name4%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name5%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name6%&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="image" src="images/tick.png" alt="" onclick='ShowName("&lt;%# ((User)Container.DataItem).Name7 %&gt;", this); return false;' /&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name8%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name9%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name10%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name11%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name12%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name13%&gt;&lt;/td&gt; &lt;td&gt;&lt;%# ((User)Container.DataItem).Name14%&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/ItemTemplate&gt; &lt;/asp:Repeater&gt; &lt;/table&gt; </code></pre>
