Hi,

I want to hide a textbox when the value of a datasource field is below a specific value (opacity = 0), if the value of the field has the specific value the opacity must be 1, if the value of the field is higher than the specific value the the opacity must be 0.5

I already managed the change the opacity bases on the value in the field.

I have a datasource from 0 to 1 with increments of 0.1 and when I scroll in the datasource the opacity is following

Can someone help me with this?

Kind regards
Koen Deschepper

you probably have a good reason for the 3 state opacity thing but you will not be able to do the evaluation of certain level within your XAML code. You will need code behind and compile the title into a .dll file.
On the other hand why no use regular vMix scripting checking your datasource value , test it and then do a transparency value to another textblock that is binded to your opacity of your text
Or use it to set the alpha of the title (input)

Hi doggy,
thx for your quick reply.

I need to control 12 textboxes so playing with the alpha of the title is not an option.
I will go for the scripting in vmix.

Kind regards
