                string scriptstring = "radalert('select a destination to copy', 330, 210);";

     else
            {
                // proceed with copy functionality logic
            }
} 

On button click i need the radconfirm popup and when the users selects ok then it shud come here and check the nodes count and rest will go as usual. If i used the _postback the entire page loads which i don't want. So how to handle this scenario. Please let me know.

Hi,

I am building an web application that will be used on several types of clients amongst which some pentium 4 2ghz with 256 mb internal memory (win xp pro, IE 6).

One of the web pages uses Telerik's AJAX controls for dis/enabling and populating controls based on selected values of other Telerik comboboxes. These controls are nested in a table with about 15 rows and 4 columns per row. There 14 controls on the page in total (all RadTextBox, RadMaskedTextBox, RadComboBox for ASP.NET Ajax (version 2008.1.619).

This page is extremely slow on the older clients. It sometimes takes more than 30 sec to update the page after a control has been changed by the user. The loadingpanel is shown and shows the spinning but after some seconds the wheel stops turning and nothing seems to happen. Finally, the loadingpanel disappears and the page update is complete.

I have tried two setups:
1. RadAjaxManager with one RadAjaxPanel around the complete table. The RadAjaxManager has one AjaxSetting to have the RadAjaxPanel update itself

2. RadAjaxManager with several individual AjaxSettings to have the controls update certain other controls and no RadAjaxPanel:

The second approach seems a bit faster than the first but still the page takes a long time to load.

Anyone any suggestions on the best approach in this situation and perhaps some background information why the second setup is a bit faster than the first?

Regards,

Mark
