ProgressBar does not update untill after work is done!

Hi, I have an import feature that I want to display progress while its running.
the import feature is located in a MdiChild
the progress bar is located in a radStatusStrip on the Parent form

here is the code I have and yet the Progress bar doesn't move untill after the loop is done.

int j = Textbox_InputText.Lines.Length;
(ss.Items[1] as RadProgressBarElement).Maximum = j;
int i;
            for (i = 0; i < j; i++)
            {
                ....Do import stuff

                //I tried .Value++ also and same results
                //(ss.Items[1] as RadProgressBarElement).Value1++;
                (ss.Items[1] as RadProgressBarElement).PerformStepValue1();



            }

PLEASE Help, I am extremely frustrated with this.

CreateNode event not fired

AllowAdd = true;

When I right-click a node and choose "New", I want to make sure that the Tag of RadTreeNode is set to some important data. I'd expect the CreateNode event to solve this:

private void radTreeView_CreateNode(object sender, CreateTreeNodeEventArgs e)
{
e.Node.Tag = obj;
}

However, this event is not called when I choose "New". Is this a bug or a feature?

Images not updated until scrolling

I'm adding all my nodes in the NodesNeeded event. Then, in the NodeFormatting event, I'm changing the image of the nodes using the ImageKey.

The problem is that NodeFormatting is not called for all visible nodes. It seems it gets called for arbitrary root nodes when I expand one of the roots or when I scroll up and down. What's going on?

UPDATE
If I explicitly set the ImageKey when adding the nodes (which I don't want to do), then all images are updated when I click inside the tree view. Calling Refresh() after adding the nodes does not help.

UPDATE 2
Another problem... when I double-click node A its icon changes to "Open" and is kept open until I select one of its child nodes. When a child is selected, the icon changes to "Closed". I have put breakpoints at all places where I set the icon to "Closed" and it does not fire. Hence, for some reason, the RadTreeView manages to revert the icon to its previous state...

RibbonBar not honoring Theme

When a ribbon is added to my main form, the main window looses its theming for the title bar and window borders.

Steps to reproduce:
Version 2012.1.321.40 Trial
Create a new project - make it a Telerik windows application.
Drop the Office2010Black them on the form in the Designer.
Add the following to your form constructor:

public MainForm()
{
InitializeComponents();
ThemeResolutionService.ApplicationThemeName = "Office2010Black";
}

Run the application. Notice the tile bar is themed. The thing looks nice.

Now add a ribbon bar.
Tell it that it is fine to add the behavior it wants to.
Add a new tab and a new group.
Run the application.

Notice the title bar is no longer themed. Basically it looks really ugly. See the attached PNG file.

What do I need to do to make the entire application honor the theming?

Thanks in advance for your great support.

RadPageView Auto Size Problem, ExplorerBar Mode – PageViewPage AutoSizeToBestFit

Hello,

I would like the RadPageViewPage to automatically resize itself to its contents when the contents is changed.

It appears that when the contents of the RadPageViewPage is changed its height stays the same. fig1 shows the height before content is modified fig2 shows the height after content is modified(pressing ‘Next’ button), fig3 shows the height after one of the RadPageViewPage tabs is clicked, clicking 'Next' after that keeps the same height. It appears that if a tab is clicked the RadPageView resizes itself. So how can I make the RadPageView resize itself to its content programmatically.

Code to reproduce:

public Form1()

{

InitializeComponent();

var spa = new SplitContainer()

{

Orientation = Orientation.Horizontal,

Dock = DockStyle.Fill

};

spa.FixedPanel = FixedPanel.Panel2;

spa.SplitterDistance =300;

this.Controls.Add(spa);

var rpv = new RadPageView()

{

Dock = DockStyle.Fill,

ViewMode = PageViewMode.ExplorerBar

};

((RadPageViewExplorerBarElement)rpv.GetChildAt(0)).ContentSizeMode = ExplorerBarContentSizeMode.AutoSizeToBestFit;

var pag = Enumerable.Range(0, 3).Select(a =>

new RadPageViewPage() { Name = "Page" + a, Text = "Page" + a, IsContentVisible = true }

);

rpv.Controls.AddRange(pag.ToArray());

spa.Panel1.Controls.Add(rpv);

var cn = 0;

var b1 = new Button() { Text = "Next" };

b1.Click += (o, e) =>

{

var cpag = rpv.Controls.Cast<RadPageViewPage>().ToList();

cpag.ForEach(a => a.Controls.Clear());

cpag.ForEach(a => a.Controls.Add(new RadLabel() { Text = (cn++) + "\na\nb\nc\nd\ne\n" }));

};

spa.Panel2.Controls.Add(b1);

}

Any help would be appreciated,

Pie Chart Shows "0%" Near Title

Hello,

I'm using version 2012.3.1310.40
I use ChartView to create a pie chart with the following data
Assets          2248550.22
Income             19748.67
Equity           2228253.95
Liability                 547.60

So, when the chart displays, the Percentage is set as follows:
Assets       50%
Income        0%
Equity         50%
Liability        0%

I notice when the percentage is 0% for any data, the pie chart shows "0%" near the chart title (please see attachment). Or if the calculated data returns 0, it doesn't show any percentage on the chart, but it shows "NaN" near the title as well. (please see attachment).

Any idea why?
Thanks in advance for your help!
Chris

[Solved] RadSplitButtonElement brighter than other button elements using Telerik's themes

I've having some trouble trying to display a RadSplitButtonElement as item of a RibbonBarGroup.
I'm expecting the RadSplitButtonElement to use the same backgound/foreground color as the
other types of buttons once I've applied any of the following themes:
. office2010black
. office2007blue...

As shown in the attached pictures, the element is painted using a brighter color than the other
elements, even when being inactive (which makes it really really visible in my GUI)

I cannot figure out if this may be considered as a bug or was really designed to be displayed like this.
What would you recommend to get the RadSplitButtonElement being displayed with the same default
settings than the other button elements ? Should I build a custom version of the office theme ?
Override a custom RadSplitButton ?

Moreover, as pictured in file inactivesplitofficeblack2010_after, the font color of the split button
remains dark blue once i've applied the office2007blue theme and came back to the office2010black theme.
This issue can also be reproduced with the telerik theme viewer which came with the Q3 2012 release.

Is that already a known issue ?

Thanks a lot,
Antoine.
