Adding new lines to RichTextbox with different colors

[Jzzocco86]

I am trying to add lines to a richtextbox using .appendtext. Things work fine with the first line, however once I add an new line the whole box changes to the new color.

Below is the code that runs on a submit button. The colors are choosen from a set of radio buttons ($global:textcolor) and there is a text box to type in some text ($mainTextbox1)


$mainButtonSubmit_Click = {
$mainRichTextbox1.ForeColor = [Drawing.Color]::$($global:textcolor)
$mainRichTextbox1.AppendText("$($mainTextbox1.text)`n")
}

Any assistance would be appreciated

You have to select the text to add the color or use RTF color commands with the test.

Thanks for the advice. I am new to using powershell GUIs can you provide a code snippet or article to help.

Here is an old demo of how to add color.

Thanks for the response. I tried that last night but it appears that .SelectionColor is no longer a command. i get the below error message. Am I doing something wrong?


The property 'SelectionColor' cannot be found on this object. Verify that the property exists and can be set.
MainForm.psf (44, 2): ERROR: At Line: 44 char: 2
ERROR: + $mainRichTextbox1.SelectionColor='red'

Heres the updated snippet.

$mainButtonSubmit_Click = {
#$mainRichTextbox1.ForeColor = [Drawing.Color]::$($global:textcolor)
$mainRichTextbox1.SelectionColor='red'
$mainRichTextbox1.AppendText("$($mainTextbox1.text)`n")

Did you actually try and run my example. It works so your form must not be using a richtextbox.

"SelectionColor" is not a command. It is a property.

My apologies for using the incorrect terminology, I am still learning.

Thank you I was not apparently using a richtextbox, I was using a normal textbox.

Once I changed it to a richtextbox things started working as expected.

Thanks again for the help

No need to apologize. It is a common mistake but know you know.
