I have a simple Silverlight example that I cannot get to work. I noticed that this issue has come up before in the Forum, but I could not find out whether there is a solution, or it is a bug.

I have a tab control with two tab items. In each tab item I have a TChart control that is supposed to stretch to fill the tab item. If I assign a fixed size to the TChart control in the first tab, then the TChart in the second tab will automatically stretch. If I try to make them both stretchable, then the designer preview fails. If I replace the TChart control in the first tab item with a simple button, the button correctly stretches and so does the TChart control in the second tab item. I have tried all kinds of variations but I cannot get both TChart controls to stretch automatically. See attached code. Remove the hard coded dimensions of the first TChart control to reproduce the problem.

Can you help?

Thanks,
Kent

Hello Kent,

I have tested your project and I could reproduce your problem here with your attached code. But, I have been debugging your code, and I found that if I comment StackPanel lines, the first Chart automatically stretch. Please, could you tell us if commenting StrackPanel code works as you want and if it is a good solution for you?

Code: Select all

<!--<StackPanel>
                    <Button Content="button 1"/>-->
                    <!--<my:TChart Name="tChart1" Height="420" Width="620" Margin="0,0,0,0"></my:TChart>-->
                    <my:TChart Name="ChartHMICBEMA"  VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0,0,0,0" />
                    <!-- GetAxisLabel="ChartHMIDisplay_GetAxisLabel" GetNextAxisLabel="ChartHMIDisplay_GetNextAxisLabel" ClickLegend="ChartHMIDisplay_ClickLegend" -->
                    <!---MouseDown="ChartHMICBEMA_MouseDown" MouseUp="ChartHMICBEMA_MouseUp" MouseWheel="ChartHMICBEMA_MouseWheel"  MouseMove="ChartHMICBEMA_MouseMove"-->
                <!--</StackPanel>-->

I hope will helps.

Thanks,

Removing the StackPanel did not solve the problem. The chart in the first tab still does not stretch. The chart in the second tab does stretch.

Hello Kent,

Using next code, last version of TeeChartSilverlight and commented StackPanel both charts are Stretch automatically:

Please, check that previous code behaves like in your application and you get same results that us images. If it doesn't work like, please, you could tell us what version of TeeChartSilverlight you are using

I hope will helps.

Sandra,

I copied and pasted your code into a new project. I am not able to load the silverlight design page in the Visual Studio designer.
I am using Visual Studio 2010 (Version 10.0.30319.1 RTMRel).
I am using TeeChart.NET (Version 4.0.2010.27967 file version 4.0.2010.27966)

I get the following error if I do not provide a Height and Width property for the first TeeChart control:

Hello BlueMonkey,

I have tested again your code and I could reproduce the problem here with TeeChart2010, and I solve it changing the name of application thus:

Code Class name:

Code: Select all

x:Class="SilverlightApplication1.MainPage"

Change for your class name:

Code: Select all

 x:Class="SilverlightTestApplication.MainPage"

Could you please check again if your code works when you change class name and say us if now works as you want?

I hope will helps.

Thanks,

Sandra,

If I change the application name, then it does not match the content of the code behind file and I get a build error:

Error 1 The name 'InitializeComponent' does not exist in the current context

This problem seems to be specifically related to the Visual Studio design view. If I specify constant Width and Height properties, the design view appears and the application will run and display the fixed chart dimensions. If I remove the fixed chart dimensions (leaving the stretchable properties) then the design view gives the error "Value does not fall within the expected range.". However if I run the application in spite of the error in the design view, then the chart window will appear stretchable.

The conclusion is that if I want to see the design view of my GUI, I must supply fixed TChart dimensions. If I want to have a stretchable TChart in my runtime application, I must remove the fixed chart dimensions. I cannot have both.

It would be nice if the TChart would display correctly in the VS design view for both cases. Is this something you can fix?

Sorry, I think that I didn't understand your previous post correctly, but now I could reproduce your problem and I have added it in bug list with number [TW24015010]. We will try to fix it in next versions of TeeChartSilverlight.
