Disable Enable button on dropdown selection

[Anonymous]

Hello Experts,

i want button to be enable or disable on dropdown selection. in dropdown either value will be filled or it will be blank. If dropdown has value button will be enable otherwise disable . so i am writing this on dropdown ONChange property:

If(IsBlank(Dropdown9_1.Selected.Result),UpdateContext({var3:true}),UpdateContext({var3:false}))

on button DisplayMode:

If(var3=true,Disabled,Edit)

 But button is always active not following condition , am i making any mistake :? , i tried with ISEmpty function , still same. please advise

I suggest you remove the formula on the OnChange if the objective is to change the display mode based on the drop-down being blank.

Then

Change the formula on the display mode of the button to;

If(IsBlank(Dropdown9_1.Selected.Result),DisplayMode.Disabled,DisplayMode.Edit)

Hi @Anonymous ,

I'm not getting all the context of your app, but please try to put:

If(Len(Dropdown9_1.Selected.Result)>0,UpdateContext({var3:false}),UpdateContext({var3:true}))

 and also you can use:

If(var3,Disabled,Edit)

as var3 is already a bool variable.

Hope it helps !
