Data Card Conditional Visibility

(0) Share

Report

Posted on by tagustin2020

Hello,

I have certain data cards that I wish only to appear if certain project types are chosen from a dropdown control (to confirm, it is not a combobox control). To achieve this, I renamed the data card value vPrefixType and then changed the Visible property of the data cards to vPrefixType.Selected.Value = "110-Name of Program" || "650-Name of Program”

When 110 is selected, all of the correct data cards appear. When 650 is selected, they do not appear. I’m sure it is probably a simple syntax adjustment. Your advice would be appreciated. Thank you. Teresa

So in PowerApps you cant set variables like you do writing code with python, java, c, etc. In those languages you would do like you did and say:

varName = value;

In PowerApps you have to use either the Set(varName, value) function or the UpdateContext({varName: value});

In your case you might try setting/adding to the onVisable property of that screen and adding the UpdateContext method to set your variable. This will make that a local variable to that screen and that screen alone. If you use the variable on multiple screens you can use a set function call on app load and then you can see it from any screen in the app. Once you have decided which works better for your case, (global or local vars) then then the next step is to write your statement to decide when to make something visible. I generally use an If(condition, ifTrueValue, ifFalseValue) function. So something like If(vPrefixType.Selected.Value = "110-Name of Program" Or "650-Name of Program", true, false). So If the selected value is one of those 2 strings visibility is true else its false. Not sure if I explained too much but hope it helped! Happy Power Apping!

Hi@tagustin2020,

Please try to modify your formula as below:

vPrefixType.Selected.Value = "110-Name of Program" || vPrefixType.Selected.Value = "650-Name of Program"

Hope it could help.

Regards,

Qi
