Hi all,
I have a radgrid being loaded with a dataset at page load. We have ~60 columns in the radgrid with a bunch of radcomboboxes in each row. I need to have a OnClientFocus event on the radcomboboxes for something I am doing in jquery. I noticed my page load was a bit slower after I added this, so I added a console.log to the onfocus function, and noticed that it is being called 50+ times (I believe it is the total amount of radcomboboxes I have on the page, or at least pretty close) as soon as the page loads.
Is each one of these radcomboboxes grabbing focus on page load for some reason? Is this intended behavior? Is there anything to get around this happening?

Hi,
If the OnClientFocus event handler function is attached from the mark up to the RadComboBoxes defined in your columns than this event will be fired for every combobox in every row. You could try to add this event handler only for specific combo boxes, but this should be done from code behind. The ItemCreated event of the RadGrid should be handled and then a reference to a specific RadComboBox should be obtained. The event handler function should be attached in the following manner:
