Light Visual Element

[Filipe]

Hi,

I want to put LightVisualElement object within a radpanel or something like that, because i want to create tags like Gmail ( http://blogs.telerik.com/WinFormsTeam/Posts/09-12-15/gmail-like_labels_in_radgridview_for_winforms_no_problems.aspx ) and put them into a panel.

The telerik example link shows how to put that LightVisualElements within a custom cell in radgrid, but i need to put LightVisualElement within other controls like radpanel.

Hi,

I figure it out how to do add lightvisualelement to radpanel: <radpanel.PanelElement.Children.Add(LightVisualElement)>

Now i have another problem: when i put LightVisualElement inside a radpanel, the element fills all the size of radpanel and i want to give the element only the text size like this function do in Telerik HelpDesk demo:

protected override SizeF ArrangeOverride(SizeF finalSize)
{
    float x = 0;
    foreach (RadElement element in this.Children)
    {
        float y = (finalSize.Height - element.DesiredSize.Height) / 2;
        float width = element.DesiredSize.Width;
        if (element != textElement)
        {
            width += 10;
        }
        element.Arrange(new RectangleF(x, y, width, element.DesiredSize.Height));
        x += element.DesiredSize.Width;
        if (element != textElement)
        {
            x += 2;
        }
    }

    return finalSize;
}

Can you help me.

Hello Filipe,

The simplest way to autosize a LightVisualElement according to its content is to set the StretchHorizontally and StretchVertically properties to false:

visual.StretchHorizontally = false;
visual.StretchVertically = false;

In case of more complex scenarios, you should create a custom layout. The ArrangeOverride method of the Telerik Presentation Framework is similar to the ArrangeOverride method of WPF. For additional information about WPF ArrangeOverride, please refer to the following article:
http://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.arrangeoverride.aspx

As to the TPF ArrangeOverride, please refer to this article.

I hope this helps.

All the best,
Nikolay
