rdlc report in vs2010, how do i repeat column header on every page?

I just had this same problem and found that you likely need to go a bit further from the standard properties (right-side dialog) into the Advance properties.

After selecting your Tablix, there should be a frame at the bottom showing Row Groups and Column Groups, with an arrow at the far right. Click the arrow and select advanced mode.

Now, the RowGroups section should show (Static) and (Details1), maybe more depending upon your Tablix. Select the static row and in the right-side properties window, there will be an option to RepeatOnNewPage.

After I did this, my column headers displayed as I expected.

Good Luck!

I have had this nagging issue in my bug list for months! I want to make it clear that KDrewiske gave me the solution so don't vote for me, but I can't seem to reply to deerchao's followup question. (Sorry, I'm new to the site)

In addition to KDrewiske's solution, I had to select the second row ('Details1' from the previous example) and turn KeepTogether to false.

I now get column headers on every page and can remove a pesky bug from my list!
