Thank you for letting us know. I would try to ask our developer teams to fix it asap. If it is possible, I would send you unofficial hotfix for this before March 10th.

Hello Andre,

Thank you for your question. It gives us some insights about this. Our developer teams are planning to implement/enhance it elegantly in the next release.
But for now, actually it can be done by overwriting the export code.
First, you would need to edit the status bar item template and add the option for XML.
Secondly, rewrite/handle the export mechanism manually.
If you want, I can try to build a sample for you.

Hello,

It should not happen. Basically, it also should show time out when the response is too long. Perhaps, you can help us by giving the evidence or other details such as your code?

I can replicate the issue as well in here. I will forward this issue to our developer teams.

Hello David,

Please allow me to help you in answering your question.

1. We are binding to a SqlDataSource for the selects, but the updates and inserts are using custom objects.
The insert and updates are ok and work fine when the method onbatchupdate method is called, but the page then displays  
"WebGrid failed to update 1 out of 1 changes due to errors.Please review and correct your changes"

The following records were not updatesd.
Record '69': Object Reference not set to an instance of an object".

The code seems to be looking for the insert and update statements in the SqlDataSource which do not exist. How can i stop this from happening.?

I think the problem is not because it could not find your insert/update method. But it seems your method itself should the problem.
For simple case, try not to use batch update first. Just use regular simple insert, update and delete. See if your insert/update method are working in non batch-update scenario.

2."Accept All Changes" button on the bottom of the grid is far far too small. How do i make this button appear larger and place it at the top of the grid..

It could not be moved to the top. Even though you can larger the size, the style would be bad.
We have design each of images in status bar have their own size. 
Unless, you want to customize the style by yourself. In this case, you need to get the element of the status bar, and change the size (width and height) of the icon.

3.How do we remove "Paste Multiple rows from clipboard" in the context menu. Its buggy & not needed.

You can find it in our documentation "How-to: Add/Remove a menu in WebGrid's context menu ".
