Add the choice field to dropdown on condition

(0) ShareShare
ReportReport
Posted on by dbbbb 44

Hello,

My aim is to add the 'Rejected' option to the dropdown only if all above dropdowns have a value selected.

If some dropdowns do not have a value selected, the 'Rejected' option should be invisible.

 

Is there a way to do it? Any help would be greatly appreciated!

 

Please see below screenshots for reference:

    Hi @dbbbb ,

     

    Try the following code, ensure you replace things with your column and control names:

    //This will be in "items" property for Dropdown where Rejected should be invisible
With(
 {
 EmptyDropdownValidation: (IsBlank(Dropdown1.Selected) && IsBlank(Dropdown2.Selected) && IsBlank(Dropdown3.Selected))
 },
 If(
 EmptyDropdownValidation,
 //Insert your choices, and add this code
 Filter(
 Choices() , !('fieldName' = "Rejected")
 ),
 //All Visible
 Choices()
 )
)

     

    Hope this helps

    With(
 {
 EmptyDropdownValidation: (IsBlank(Combobox1) && IsBlank(Combobox2) && IsBlank(Combobox3) && IsBlank(Combobox4))
 },
 If(
 EmptyDropdownValidation,
 Choices('MyList'[@'Status']),
 Filter(
 Choices('MyList'[@'Status']), !(Dropdown_Status = 'Rejected')
 ,
 Choices('MyList'[@'Status'])
 )
 )

     

    Hi @Ethan_R, thanks for replying

     

    I tried your code and get an error for !(Dropdown_Status.Selected = "Rejected") : These types cannot be compared: Record, Text

     

    And for the last Choices('MyList'[@'Status'] I get an error: we expect a boolean at this point in the formula

    Hi @dbbbb ,

     

    Try the following code:

    With(
 {
 EmptyDropdownValidation: (
 (IsBlank(Combobox1.Selected) || IsEmpty(Combobox1.SelectedItems)) && 
 (IsBlank(Combobox2.Selected) || IsEmpty(Combobox2.SelectedItems)) &&
 (IsBlank(Combobox3.Selected) || IsEmpty(Combobox3.SelectedItems)) &&
 (IsBlank(Combobox4.Selected) || IsEmpty(Combobox4.SelectedItems))
 )
 },
 If(
 EmptyDropdownValidation,
 Choices('MyList'[@'Status']),
 Filter(
 Choices('MyList'[@'Status']), !(Status = 'Rejected')
 )
 ,
 Choices('MyList'[@'Status'])
 )
)

     

    Note: Status = 'Rejected', here Status is considered the field name. 

    If Status doesn't work, try "Value = "Rejected""

     

    Hope this helps

    Hi @Ethan_R, we are very close.

    The code does not produce any errors after altering the code to: !(Status.Text = "Rejected")

     

    However, when I enter the last 

     Choices('MyList'[@'Status'])

      The whole If throws an error: The function 'If' has some invalid arguments

     

    Do you have any clue what might cause this to happen?

    Hi @dbbbb ,

     

    There's a small mistake as I copied you code.

    Here's the updated one:

     

    With(
 {
 EmptyDropdownValidation: (
 (IsBlank(Combobox1.Selected) || IsEmpty(Combobox1.SelectedItems)) && 
 (IsBlank(Combobox2.Selected) || IsEmpty(Combobox2.SelectedItems)) &&
 (IsBlank(Combobox3.Selected) || IsEmpty(Combobox3.SelectedItems)) &&
 (IsBlank(Combobox4.Selected) || IsEmpty(Combobox4.SelectedItems))
 )
 },
 If(
 EmptyDropdownValidation,
 Filter(
 Choices('MyList'[@'Status']), !(Status.Text = 'Rejected')
 )
 ,
 Choices('MyList'[@'Status'])
 )
)

     

     

    Hope this helps

    Hi @Ethan_R, the code finally doesn't throw any errors. However, it does not work as expected. After leaving two ComboBoxes blank, I still can choose 'Rejected' in the DropDown. Please see below:

    Hi @dbbbb ,

     

    Please change this condition in above statements as 

     

     

    (
 IsBlank(Combobox1.Selected) || IsEmpty(Combobox1.SelectedItems) ||
 IsBlank(Combobox2.Selected) || IsEmpty(Combobox2.SelectedItems) ||
 IsBlank(Combobox3.Selected) || IsEmpty(Combobox3.SelectedItems) ||
 IsBlank(Combobox4.Selected) || IsEmpty(Combobox4.SelectedItems)
)

     

     

     

    Let me know if this works?

    As its only about this logic, I hope the conditions are met properly.

    Hi @Ethan_R, the above did not resolve the issue. However, after changing

    !(Status.Text = "Rejected") to !(Value = "Rejected"), the code started to work properly!

     

    A final question from my side: why in the EmptyDropdownValidation you check for IsBlank OR IsEmpty? Isn't IsBlank enough?

    IsBlank(Combobox1.Selected) || IsEmpty(Combobox1.SelectedItems)

    Hi @dbbbb ,

     

    It works, 

    Just from personal experience I use both of them.

     

    You can use "IsEmpty(ComboBox1.SelectedItems)" 🙂
