hello.
please look at the Image. How to formula the column by part1 and part2? thanks!
Hello Psky,
If I understand well your requirement, to solved your task, you should implement custom formula (function) into your UltraCalcManager and apply this formula to your column -"Formula5". After that each time when you make changes into your "part12" column, you should call ultraCalcManager1.ReCalc(); method.
Please take a look at the attached screenshot, video and sample for more details. Let me know if you have any questions.
Hi,Boris. you do not understand it. i hope add a formula column. it's data come from part4. the column part4 is not string.
please watch the picture.
Hello,
I am not able to understand how would you want to sum the string column and show it in the int column.
Are you looking for the summaries functionality: http://help.infragistics.com/NetAdvantage/WinForms/2013.1/CLR4.0/?page=Infragistics4.Win.UltraWinGrid.v13.1~Infragistics.Win.UltraWinGrid.UltraGridOverride~AllowRowSummaries.html?
Nobody can reply to me。How to do it?
Sorry, The last column is sum(part4) group by part12. you know?
