PowerApps Drop Down

Hey I'm new to power apps. I have a question regarding drop down.

 

So imagine I have one drop down question with choices a,b,c,d. And I have one more drop down question with choices 1,2,3,4. Now if I select "c" in the first drop down, automatically the second drop down should show "1" and user should not be able to edit this. 

 

But if I select any other choices(a,b,d) from first drop down, the user should be able to choose any choice from second drop down.

 

so how do I write a formula to achieve the above scenario?

Depending on the flexibility you need - the easiest way is to just provide the data to the second dropdown from the first.

ex.  Items property of Dropdown1:

Table(
    {Value: "a", Choices: [1,2,3,4]},
    {Value: "b", Choices: [1,2,3,4]},
    {Value: "c", Choices: [1]},
    {Value: "d", CHoices: [1,2,3,4]}
)

Then, Items property of Dropdown2:

Dropdown1.Selected.Choices

 

I hope this is helpful for you.

lets assume the first dropdown is called DropDown1 and the second dropdown2

 

change the default of dropdown2 to If(DropDown1.Selected.Value = "C","1",Blank())

change the DisplayMode of dropdown2 to If(Self.Selected.Value = "1", Disabled, DisplayMode.Edit)

 

in the above it assumes that 1 is text e.g. "1", to change it to a number you need to change it to just 1.

@Sindhu_Ambati ,

i think it should be enough the following.

On the second dropdown ->

DisplayMode:

if(FirstDropDown.Selected.Value=“c”,Disabled,Edit)

Default:

1

Hope it helps !
