Body
I have a RadComboBox that has around 400 items (from a DataBase) and I get the following JavaScript error as soon as I select "Check All": "A script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive. " To optimize the CombBox I have set LoadOnDemand to true & OnClientItemsRequesting="StopRequest", but this does not seem to help. ComboBox Properties aspx code: <pre><code> <telerik:RadComboBox ID="CUD" Width="260" Height="150" runat="server" AutoPostBack="false" CheckBoxes="true" EnableCheckAllItemsCheckBox="true"> </telerik:RadComboBox> </code></pre> Please assist me in anyway you can as soon as you can. Thank you! MyName.

1. COTry using FireFox with FireBug to see whether it's the callback to the server taking too long, or if its related to a JavaScript file running. I had that happen in 3 scenarios so far: 1) there was an infinite loop 2) the bandwidth of the client machine was very slow or 3) the page had to process a LOT of DOM elements.

Guidance

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.
