Hi,

I got a radchartview with some scatterlineseries. When the user changes a parameter, the chart should be updated with a new series. That works but the old series is still on it. I tried radchartview.series.clear, but I would need something to clear/reset the whole chart before adding the new series.

How can i do that, please.

RadMessageBox large text height problem

Hello everybody,

we´re (still) updating to RadControls Q3SP1 an we still experience problems with RadMessageBox and large text, like 4000 characters.

In the program we collect multiple messages and append them to a StringBuilder using AppendLine. If this text exceeded 4000 characters, it is cut (StringBuilder.Length = 4000) and a "text-was-cut-message" is appended, so the resulting string has about 4100 charaters and is passed to the RadMessageBoxes Show method.
The resulting MessageBox shows the whole text in the upper portion of the control and is that big (rest (half) of the messagebox is empty), you can´t click "Ok-Button", because it´s located just under the bottom of my monitor.

So, if text is that big - we have to use MS MessageBox.

What I found out while making the screenshot is, that this behaviour depends on the text. I tried to make an example where I put a space after every 50 or 100 characters and a newline after every 500 characters and the text was almost shown as expected.

Greetings,
Daniel

RadMessageBox questions

Hi,

We evaluate Q1 2009 Winforms controls with VS2008 SP1.

1) How to change RadMessageBox title font?

2) How to change RadMessageBox message font?

3) Does the RadMessageBox plays error / success sounds according to the MessageBoxIcon like the .Net MessageBox.Show ?

4) The documentation application that comes with the WinForms doesn't have an entry for RADmessagebox - where to find documentation?

5) Does the RADmessagebox support HTML? I tried <b> and </b> tags but they are shown.

6) The localization feature of the RADmessagebox buttons text is very nice :-)

Thank you!

ChatTextMessage Hyperlink

Hi,

First of all, kudos for having developed the chat control--I will be purchasing the Winforms UI license solely for this capability!

I noticed that the text of a ChatTextMessage can be HTML-formatted. When I create a hyperlink, it looks and acts like one, with the exception that the link target is not launched when I click on it. How can I overcome this?

RadBrowseEditor that accepts file OR directory

Hi,

I'm in a need for a dialog form that in the end returns a FilePath OR a DirectoryPath, with a TextBox that the user can paste something (file or directory).

I tried doing so with a System.Windows.Forms.FolderBrowserDialog but without success.

I'm turning over Telerik, found the RadBrowseEditor and calling the RadBrowseEditor .BrowseElement.BrowseButton.PerformClick() method for opening.

The best/closest DialogType is BrowseEditorDialogType.OpenFileDialog, but the problem is when pasting a DirectoryPath, the control navigates there and no event is raised (same as the system's FolderBrowserDialog, it's even the same used from Telerik).

I tried listening to events ValueChanging and also all those under the BrowseElement object, but nothing works.

Any idea (I didn't want to create a new form, developping the navigation treeview, textbox, since almost everyhing is there)?

thanks

Secondary Axis without data series

Hi,

I would like to add a secondary x-axis to my chart (having relative instead of absolute values) without a belonging data series. But I have problems to get this axis shown. With the following code, the axis is simlpy not shown:

// Secondary x-axis with percent values of current price

LinearAxis horAx2 = new LinearAxis();

horAx2.VerticalLocation = AxisVerticalLocation.Bottom;

horAx2.Minimum = Math.Round(_minX / ulPrice, 4);

horAx2.Maximum = Math.Round(_maxX / ulPrice, 4);

horAx2.MajorStep = Math.Round(ulPrice * 0.03 / ulPrice, 4); // 0.05; // 1 Prozent gerundet //Convert.ToInt16(units)*10;

horAx2.Font = new System.Drawing.Font("Ubuntu", 10F, System.Drawing.FontStyle.Bold);

Is it possible to a secondary axis without a complementay data series?

Thank you

Changing TitleBar colour of a RadForm

Hi,

I'm in the process of evaluating your winform controls and I'm trying to emulate the way the demo app hub changes the title bar of a form, size and colour. For example when selecting the Grid Example the header is about 80 high, dark blue with a back button.

The app I created has a simple Radform and Rad Data View, on load I try to change the TitleBar, but I must be doing something wrong.
I can change the background colour but the background of the system buttons stay the same.

Here's a snippet
this.FormElement.TitleBar.Size = new System.Drawing.Size(this.Width, 100);
this.FormElement.TitleBar.FillPrimitive.BackColor = Color.DarkBlue;
this.FormElement.TitleBar.CloseButton.ImagePrimitive.BackColor = Color.Transparent;

I has also tried to create a new RadTitleBarElement, but the out come is the same.

I know I'm missing something simple here so can you point me in the right direction?

Cheers
Shaun.
