Text search of "system.serviceModel" in the C:\Program Files (x86)\Microsoft Visual Studio 10.0 doesn

What is the difference between matrix and a tablix?

阅读更多关于 What is the difference between matrix and a tablix?

问题 In Reporting Services. When I drag in a matrix, am I effectively dragging in a tablix? A tablix is a hybrid of table, list, and matrix.

Even though I am suppressing unused groups from displaying, they are still taking up space. Here's what the report looks like now when I choose only one row group and one column group: Notice how even though the undesired groups have property hidden True (as set by an expression)

I'm trying to make a report in BIDS (2008) that will include external images. We want to use the report to proof the images & other info before we approve our flyer for printing. I've done a bit of searching, but haven't gotten the help I need yet. The path to the images will be image specific, like "\\NETWORKSERVER\ServerD\Docs\Flyer's Images\Quarterly Flyer\ImageName.png" The URL works fine when I paste it in the search bar of my local pc or the server that has BIDS installed on it, but the report will not display the image.
