Dear Telerik Wizards,

How can I load the images in a datagrid using AJAX / RadAjax?

I have a large number of images in templatecolumns in a datagrid (up to 100 images) and it is really slow loading the whole grid because of the images.  I would like to display a loading panel for each image while they are loading to speed things up.  Is this possible?  Note that I want this to happen as soon as the page initially loads.

Alternatively, can I show a loading panel for the whole datagrid while it loads?  I can figure out using loading panels when triggered by a client event but I can't figure it out on loading from the start.

Please Help!

Thanks.

Hello Alec,

You can create basic HttpHander which will stream the image asynchronously. Thus when RadGrid has loaded all the other images will continue loading.

You can find sample application illustrating this functionality attached to this post.
