I haven't dealt with datagrids so I may be off on this, and somebody please correct me on this if I am.

I would think the preloader would be in the on load procedure of retreiving the data. On your preloader if it is just text you could add some text to saying "loading.." because you do not load text with a file size. Now if it is images you can load them with a byte or percentage preloader.

This is about the best answer I can give without knowing anything about what you

a "preloader" relates to givning an indication of the time it requires to download a large file from your web server like a movie. In a data grid. The data must be populated by your server (like apache/php) before it is sent to the client (flash) to be viewed. Thus there is no reason to do a "pre-loader" for a data grid. You should limit your result set to your grid so there will be zero delays. Pre-loaders only make sense for things like large graphics or movies (large file size). Data in a grid is text and comparitively small.

I want a preloader to show the user that data is being loaded , the time while data is loaded from server to client datagrid ,interface shows no response or indication of data loading ,so user thinks that there is no response and keeps on clicking the button.

I have not tried it but can't you simply take the code for a preloader of a picture and apply that code to your data grid? I question the need of a preloader because a picture is a large file the text data going into a data grid is very small and I would argue that you shouldn't need one. Your data grid data likely to arive at the same time as your html and swf file.
