The tablix 'Tablix1' is invalid. The value for the DataSetName Property is missing - Help

Question

For some weird reason i can not run my report, when i try to preview i get this error:

(PLEASE RIGHT CLICK THE IMAGE AND CHOOSE VIEW IMAGE TO SEE IT LARGE)

Here is how my tablix property looks like:

Any idea what to do? The current .rdl was copied from another one. I changed the newly copied .rdl values to match my needs. I always do that and works perfect, instead of creating the design from scratch every single time.

Answer 1

Just right click on your table => tablix properties=> and set dataset name you want from dropdown and then execute.

Answer 2

Looking at your pictures, in the picture up top the error mentions 'Tablix1' is invalid. The 2nd Screenshot, the name of the Tablix is 'Tablix2'. Try changing the name back to 'Tablix1', or using the Properties section see if you can select Tablix1 in the drop down, and possibly delete it.
