Form automatically resizing

[Phillip Foster]

I'm sure the answer is already out there somewhere, but I couldn't seem to find it.

I seem to have this same problem on both of my development machines. 

When using a RadForm, the form resizes at random. I make the form to be something like 800x400, but when i tab to code and then back, or when i compile and launch the application, the size is 800x200.

I'm sure that i've done something wrong, but not real sure what it is. 

thanks!

Hello Phillip,

Thanks for contacting us and for reporting this issue.

Could you please give us further details on the case like whether you have set the AutoScaleMode property of the form to Font? If yes, please try setting it to None and see whether the issue will persist.

Thanks for your time.

Best wishes,

I checked the autoscalemode and it was set to Font, however when i changed it, It still did the same thing.

Please view the attached images to see what I mean.

Any other suggestions? this problem is still happening. It seems to be during the OnPaint or something. If I minimize and restore the form is about an 1.5" shorter than before. See Attached document.

Thanks.

Hi Phillip,

Since we are not able to reproduce the issue on our side, we would like to kindly ask you to prepare a simple Windows Forms application that reproduces the case and send it to us in a new support ticket. In this way we will be able to directly debug it and see what goes wrong.

Thanks for the understanding and for your time.

Hi,
I am also experiencing this problem.  It is fine on my dev machine but when  i give the app to someone else to run on thier machine they get the issue.  They get the issue on just opening the app but then if they change the screen they are viewing it on (dual screen) then the window repaints differently .  I have tried matching resolutions with the other machines and opening. Mine is still ok and theirs still has the issue??? also tried running it on a machine exactly the same as mine and they get the probelm as well. 

Are there any solutions to this yet??  If you need an exmple give me an email address and i can send you my project...  I have also created a support ticket for this as it is urgent...

Thanks Aaron

Aaron,
This may  or may not be the same issue that you are experiencing. They did eventually send me a work around to keep the issue from happening. the cause of the issue was because I had a Large Icon in my title bar (128x128, see screenshot). Each time the screen painted, the application did not take the large icon size into account and therefore paints the form smaller than it should. As a workaround, you must insert this block of code:

#region Overrides
     private const int WM_SETICON = 0x80;
     protected override void WndProc(ref Message m)
     {
         base.WndProc(ref m);

         if (m.Msg == WM_SETICON)
         {
             this.SetClientSizeCore(
                  this.ClientSize.Width,
                  this.ClientSize.Height);
         }
     }
     #endregion

It seems to be working for me.

Hello

Thanks for the help but i tried the code and it didnt work.  There seems to be a resizing heiarchy problem and the controls are not auto resizing based on their parent control.

Many thanks

Aaron

Hi Hatam,

Thank you for writing.

We already have similar issues reported in our Feedback Portal. However in all the cases the form size is growing. This is why I want to kindly ask you to take a look at these cases and try to find any connection with your case. The items are located here and here.

Also the provided information is not sufficient for me to reproduce the observed behaviour. This is why I want to kindly ask you to open a support ticket. In it you can provide us with your project together with the exact steps that I need to take in order to reproduce the issue on my end. 

Once I am able to do that, I will be able to investigate it and provide you with adequate support.

I am looking forward to your reply.

Hello
I was able to fix the issue by lowering Font size of the Title bar for my forms , when it's higher then like 9.5pt , the title bar can't handle it and makes this bug , i hope this helps for others with the same problem too.
