I have an Element that Inherits from LightVisualElement. In CreateChildElements I add three controls - StackLayoutPanel, Image and Label - however the Size is always 0 which causes problems in another controller where I try to stack several Elements together.

Why is the Size 0?

When is the Size initialized?

protected override void CreateChildElements()

{

base.CreateChildElements();

mainPanel = new StackLayoutPanel();

mainPanel.Orientation = System.Windows.Forms.Orientation.Horizontal;

checkBox = new LightVisualElement();

checkBox.DrawText = false;

checkBox.ImageLayout = System.Windows.Forms.ImageLayout.Center;

checkBox.ShouldHandleMouseInput = false;

checkBox.NotifyParentOnMouseInput = true;

mainPanel.Children.Add(checkBox);

label = new RIOLabelElement();

label.TextAlignment = ContentAlignment.TopCenter;

label.Font = new System.Drawing.Font("Segoe UI", 8, FontStyle.Italic, GraphicsUnit.Point);

label.ShouldHandleMouseInput = false;

label.NotifyParentOnMouseInput = true;

mainPanel.Children.Add(label);

this.Children.Add(mainPanel);

}

Nested PageView

I am dynamically adding tabs to a pageview. How can I add subtabs?

When I click on a tab, I need the tabs within the top tab to show.

Here is the code I have. The first set of tabs work. Can't figure how to add child tabs

//create a tab for each line

DataTable dt = GetLines();

if (dt.Rows.Count > 0)

{

foreach (DataRow row in dt.Rows)

{

RadPageViewPage newLine = new RadPageViewPage();

newLine.Text = row["DEPARTMENT_DESCRIPTION"].ToString();

pvMain.Pages.Add(newLine);

//get the list of what runs on each line (by Department_id)

DataTable dtLines = GetLineDepartments(Convert.ToInt16(row["DEPARTMENT_ID"].ToString()));

if (dtLines.Rows.Count > 0)

{

foreach (DataRow rowDept in dtLines.Rows)

{

// add depts tabs to the line

RadPageViewPage newDept = new RadPageViewPage();

newDept.Text = rowDept["LINE_DESCRIPTION"].ToString();

//newLine.Controls.Add(newDept); //how do I add to the newline RadPageViewPage

newLine.

}

Radscrollablepanel scrolls up automatically

Hello,

I have this annoying issue about the radscrollablepanel, what i do is inside the scrollablepanel i put a radgridview on it.
When the gridview is populated the radscrollablepanel adjust and works well, but the issue is when you scroll at the middle or bottom part
of gridview and click on row or cell. It automatically scrolls you up into the top instant and by that you cant edit something in rows which you have scrolled.
Is there any ways to stop the scrollablepanel in scrolling automatically?

Save and load to xml using MemoryStream

Hi

I'm trying to save and load a RadDock layout to a database field using a MemoryStream but the code fails on loading the layout with error 'System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1.'

I have very similar code to save and load layouts for RadDock and it works. Also I can save and load dock layouts if I use xml files but I don't want to use them.

I'm using Progress OpenEdge andthese are code snippets for saving and loading the layout.

METHOD PRIVATE VOID SaveDockLayout( ):
    DEF VAR l_MemoryStream AS System.IO.MemoryStream   NO-UNDO.
    DEF VAR l_UTF8Encoding AS System.Text.UTF8Encoding NO-UNDO.
    DEF VAR lc_char        AS LONGCHAR                 NO-UNDO.

    ASSIGN
        l_MemoryStream = NEW System.IO.MemoryStream()
        l_UTF8Encoding = NEW System.Text.UTF8Encoding()
        .
    radDock1:SaveToXml(l_MemoryStream).
    lc_char = l_UTF8Encoding:GetString(l_MemoryStream:ToArray()).
    COPY-LOB FROM lc_char TO tt_stored_layout.layout.

    l_MemoryStream:Close().
    l_MemoryStream = ?.
    DELETE OBJECT l_MemoryStream NO-ERROR.
    DELETE OBJECT l_UTF8Encoding NO-ERROR.

END METHOD.

METHOD PRIVATE VOID LoadDockLayout( ):
    DEF VAR l_MemoryStream AS System.IO.MemoryStream   NO-UNDO.
    DEF VAR l_UTF8Encoding AS System.Text.UTF8Encoding NO-UNDO.
    DEF VAR lc_char        AS LONGCHAR                 NO-UNDO.

    COPY-LOB FROM tt_stored_layout.layout TO lc_char.

    ASSIGN
        l_UTF8Encoding = NEW System.Text.UTF8Encoding()
        l_MemoryStream = NEW System.IO.MemoryStream(l_UTF8Encoding:GetBytes(lc_char), 0, l_UTF8Encoding:GetByteCount(lc_char))
        .
    radDock1:SuspendLayout().
    radDock1:LoadFromXml(l_MemoryStream).
    radDock1:ResumeLayout().

    l_MemoryStream:Close().
    l_MemoryStream = ?.
    DELETE OBJECT l_MemoryStream NO-ERROR.
    DELETE OBJECT l_UTF8Encoding NO-ERROR.

END METHOD.

Can you help or give me an example of using a method to save and load dock layouts withouth resorting to xml files?

Kind regards

Tung

Theming dockControl

Hello

I'm using ThemeResolutionService.LoadPackageFile to load a tssp file and apply the theme for the whole application with ThemeResolutionService.ApplicationThemeName = AppliThemeName;

My RadForm (F1) has MdiChildren detect by a RadDock (RD1).

One of these MdiChildren is an other RadForm (F2) which contains a radDock (RD2) which contains some others RadForm (F3x) added with DockControl method.

The F3x RadForms are not themed.

Is there anything else to do for apply theme in this case?
