Not work when Set DisplayMode to Disabled by if condition

[Ed_Cheung]

The Problem is when I only type in title and issue description the create button change to edit mode, it seem did not check the site and categories fields.

I tested I choose a value of categories choice and cancel it, then it work. So I set the default and DefaultSelectedItem to Blank(), it still not work on initial state. Any thing I done wrong?
 

I using SharePoint list to store the information.
Title data type: text
Issue description data type: text
Site data type: choice
Categories data type: choice

Hi @Ed_Cheung ,

The reason is even if no item is selected in the Combo box, by default, there is a Blank() record in it. Only if you select some item then de-select it IsEmpty() would return true. See below screenshots:

.

So, for above reason, IsBlank() is the way to achieve your goal.

Hope this helps.

Hi @Ed_Cheung ,

After a bit more test I found that IsBlank(Combobox.Selected) would return true if nothing selected in the combo box:

So you need to replace that two IsEmpty() function with IsBlank():

If(
   IsBlank(Title_DCValue_CreateForm.Text) ||
   IsBlank(IssueDescription_DCValue_CreateForm.Text) ||
   IsBlank(Site_DCValue_CreateForm.Selected) ||
   IsBlank(Categories_DCValue_CreateForm.Selected),
   DisplayMode.Disabled,
   DisplayMode.Edit
)

Hope this helps.
