Helle I have the following problem:
I have a datatable with many rows. OnCheck on checkbox in a row I can change this in the database as well. But if I click the masterCheckbox I do not want to update each row in the database but update all at once. but when I use “onHeaderClick” and “onCheck” always onCheck comes at the first place…
How can i prevent the onCheck event when I use the onHeaderClick event???
Thank you so much
Michael
Hello,
Not sure I understand why “onCheck” is called when “onHeaderCheck” is executed. It might be easier to understand the problem you’re facing if you’d prvide a Code Snippet.
For what it worth, I did not find a way to “prevent” a check form happening, but what I usually is “revert” the check value of the row without making any changes to the DB.
Here’s a code snippet where clicking on header id flipping the the value form the dataSource without event “onClick” being called: Code Snippet
I hope this helps, but in any case if you add more details I’ll take a look and try to answer you best I can.
Have a nice day!

Hello Michael
To prevent the onCheck event when using the onHeaderClick event its better to
disable the data processor (row 13) so that it does not keep track the updates, and instead of saving individual records, create your own query (row 25).
Please check the example: Code Snippet
Thanks a lot Natalia…
