RadCheckBox readonly

[superold]

Hi,

How can I simulate read-only on a RadCheckBox? the Enabled property changes the text as well.

Thanks,

Hello Jorge Delgado-Lopez,

As far as I understand your question, you would like to prevent a RadCheckBox from changing its toggle state without changing its visual appearance. To do this, you could handle the ToggleStateChanging event and set the Cancel property of the arguments to true.

If you have any additional questions, please contact us.

Hi, 

Thanks for the answer, but I need the actual checkbox to show as "disabled". The problem is that when I disable a checkbox the text changes as well. 

thanks

Hello Jorge Delgado-Lopez,

I have tested the RadCheckBox setting its Enabled property to false, but I did not manage to reproduce the behavior you are describing - the text remains the same, as it should.

In your particular scenario, there should be something else that causes this. Please, give us additional details or send us a small application that demonstrates this problem so we could test it locally. It will help us address any potential issue faster.

Contact us again if you need any further assistance.

Kind regards,

Hi, I'm having the same problem.

I have a checked radCheckBox and when I set it to enable = false, it show as unchecked.

I need a ReadOnly property and cant find it, its not good for me to handle the toggel event.

which property can i use?
I need to prevent the RadCheckBox to change state by the User actions but to show me the state it is on.

thanks

Hi Lior,

We have already addressed this issue in the latest release - Q3 2012 SP1 (2012.3 1211). We recommend upgrading to the latest version in order to take advantage of this and other fixes and improvements.

I am not able to provide you with work around for previous versions of RadControls for Winforms. 

Kind regards,

To get it to work it seems like you need to set the .Checked-property and THEN set .Enabled to false to get it checked. If the control is set disabled in design it does not get checked.

Hello Stein,

Thank you for sharing your workaround for this issue with community.

I would like to mention that we have already addressed this issue and only the users with version prior Q3 2012 should use this workaround.

Should you have any other questions, do not hesitate to ask.

Hi, I think the issue is still open.  If you are using the default theme, it is ok.  However try using a different theme (like VisualStudio2012Light) and the problem is still there.  I'm using the trial version though.  Can this be fixed by just using the theme editor, if yes, how?

I saw from another thread how to modify the theme of the checkbox by making the forecolor transparent but unfortunately it didn't work for me.  The code below (called from Form_Load) will not display the checkbox properly.  It is always unchecked using a different theme like VS2012Light.

checkbox.Enabled = false;
checkbox.Checked = true;

Anyone?

Hello Dennis,

Thank you for reporting this issue.

This is a regression one and I am reopening the case.

I am not able to provide a workaround through Visual Style Builder because this theme uses images to draw the Checkmark and this image is missing for the disabled state. As a workaround, I can suggest to set the enabled state to true (if false) and then set the Cheked property:

private void SetCheckState(RadCheckBox radCheckBox, bool isChecked)
{
    radCheckBox.Enabled = true;
    radCheckBox.Checked = isChecked;
    radCheckBox.Enabled = false;
}

Please refer to the attached sample project that demonstrates this approach. I hope this helps.

Hi,

Was this fixed in the latest Q2.2013 release?

Hello Dennis,

Thank you for writing back.

We changed the internal structure of the RadCheckBox in order to address this shortcoming and the issue should be fixed in Q3 2013.

I hope this helps.
