I think the loading image positioned in the grid pager works fairly well, but it has a couple drawbacks. For one, it is not always noticeable. If the grid is tall and the user clicks on a column header to sort, they are not necessarily going to see the grid pager loading image. So, they might be wondering if anything is going on. Also, if the grid doesn't have paging enabled, then the pager isn't displayed. so you get no loading image. The solution would be to provide a loading image which is displayed over the entirety of the grid content (not the column heders, command item, pager/footer, etc.. just the rows). Can you provide a way of accomplishing this?

Also, IMO it would be good if you move the default loading image here. It seems like a more natural location for it.

As an example.. I believe your Rad Window Loading IMage used to be in the Window status bar, and now it appears in the center of the window.. much better behavior.

The grid's pager is sometimes impossible to see without scrolling the page, and not visible at all under certain circumstances (ie when paging is not used). This makes it a poor location for a loading panel which is supposed to be displayed whenever a grid command is being executed. This loading panel should always be visible, so Telerik needs to come up with a different place to display it.

My recommendation would be to have a loading panel appear over the rows of the grid.. the actual stuff which is being changed by whatever grid command is being executed (sorting, filtering, etc.). However, the specific location isn't that important so far as the loading image is always visible and obvious to the user.

Hello Albert,

Please download the attached example (simple website) and let me know whether the demonstrated behavior suits your needs. You only need to add the DLL files to the BIN folder in order to run the website.

Again... its not about whether it is possible to add a large loading image to a grid. This is obviously possible. Its about the poor location of the built-in loading image. And it seems, in addition to being in a poor location, it doesn't even behave properly in some circumstances, as is outlined in this thread:

I really think telerik needs to rethink the grid's status bar loading image. They did so with RadWindow with great results. Why is RadGrid being ignored?

Hello Albert,

We appreciate your feedback. It is actually possible to put the loading panel in any place you want with a few lines of code needed to tweak its location. I believe there is no "universal" place where we can put that image because every project have its own requirements. I'm not trying to convince you that the current location is the best one, however moving the image to another place will most probably require introducing a breaking change which we'd like to avoid. What's more important is that you can actually tweak it the way you need as I mentioned above.
If you believe that there is a bug in our control I would recommend that you submit a bug report with a simple project attached so that our developers can debug and then eventually fix it.

I have once again encountered a situation where the default loading image location is causing issues. I have a grid with no paging. Hence, no pager. Hence no loading image. The grid has an edit form which takes time to initialize. When the user clicks on an EditCommandColumn button. Nothing happens... for about 5 seconds. My customer asked me why the loading image does not appear and I told them it was because there is no paging in the grid. When they asked me why the grid requires paging in order to display a loading image, I had no good answer.

Its been 4 years since I brought this issue to your attention. I really don't understand why it hasn't been addressed. Its so obvious. The default location of the loading image is a poor choice in many scenarios. I'm not asking you to move the image, if some others don't care about its location or prefer it there for whatever reason. I'm just wondering why you don't create the ability to have a loading image in a more natural and appropriate location, just like you have done with RadWindow. I mean, why is providing a functional interface a priority for the RadWindow team, but not RadGrid?

You could always provide a grid property that allowed users to choose the location they prefer if you are worried about a breaking change. The issue isn't whether or not I can hack a loading image and make it work more or less the way I want. The issue is that this functionality ought to be built into the grid. I have projects that have many dozens of grids in them. I shouldn't have to add a bunch of potentially fragile client-side code, not to mention a unique loading image control to each one in order to get a grid with an appropriate loading image location. Its very frustrating to me that I raised this issue 4 years ago and it seems like you guys don't even recognize the problem. If you're going to provide a loading image in the grid which is used to indicate something is occurring, THEN THE LOADING IMAGE OUGHT TO BE VISIBLE!!!
