[WB18] Change background color of a button

Startbeitrag von Gianni Spano am 05.05.2017 11:34

Hello to all

First, i apologize for this stupid question, but this is my situation:

i have 5 buttons .
At runtime, when the user push a button it must assume a RED Background color and the other remain GRAY as background.

this is the portion of code:

for j=1 to 5
if j=1 then

Unfortunately it seems that the bg color cannot be changed at runtime.
Is it right or do am i missing something?

This is a screenshot of the window

Thanks in advance


Hi Gianni,

You can change it at runtime.

I have had issues with the iteration. You would find it works with using the proper name of the button.

I have just done a quick test and it works,

I made cmd_button_colour.
server code, ajax "disabled"

IF Static_colour..BrushColor=LightRed THEN

This works correctly.
have a quick look on my site it is there at the moment -

this code should work -IF- the button is a TEXT button. If it uses am image for the background, then the image is ABOVE your background color and will not be visible

Best regards

Hi Gianni,

Another thing to consider is that if you use indirection the affected controls need to be defined as "dynamic" type in the GUI tab.
Standard is "automatic", but since the controls are addressed via text, Webdev does not know the control needs to be dynamic.

Kind regards,

I just implemented this exact feature in WM21. As Fabrice noted, buttons with an image like those from a skin template have the background color hidden.

My code does this:

in global declarations:
gsXBtnImage is string = BTN_Antecedent..BackgroundImage

To change from the startup BG color:
BTN_Antecedent..BackgroundImage = ""
BTN_Antecedent..BrushColor = LightGreen

To return to the default BG:
BTN_Antecedent..BackgroundImage = gsXBtnImage
