I have a gallery and patching to SharePoint, inside there is a checkbox and needing to and check after the patch button is pressed. ?I have set a Reset variable to other fields but not sure how to "uncheck" the checkbox.

Set(fmsVal,Blank());Set(infraVal,Blank());Set(eucVal,Blank());Clear(imgColl);Set(resetVar,false);Set(resetVar,true);Reset(AddMediaButton1_1)=true;

Any help would be appreciated

Thanks

Hi @mezcalbean ,

Sorry, I'm a little confused. Do you want to change the value of a column through a checkbox?

If so, maybe you could try the following.

OnCheck:

Patch(DateSource,ThisItem,{ColumnName:true})

OnUncheck:

Patch(DateSource,ThisItem,{ColumnName:false})

Default:

ThisItem.ColumnName

Best Regards,

Charlie Choi

Hey, if I understand correctly you want to uncheck all boxes when pressing a button. In this case you can set the "Reset" property of the boxes to a specific variable:
And then set the on the "OnSelect" property of you button you can put:
UpdateContext({Var:true}); UpdateContext({Var:false})
The first line will set the var to "true" and thus uncheck all the boxes of the galley. The second line immediately reset the var to "false" so if you recheck boxes and reclick on the button the process will work again the boxes will once again be unchecked.
