HTMLPlaceholder Floats in SharePoint 2010

[Robert]

I am trying to create a Silverlight web part to be used on a SharePoint 2010 site.  The goal is to present some data in the RadGridView, and based upon the record selected, show an existing InfoPath report in the HTMLPlaceholder.  This works as expected within the VS 2010 development environment, but once the XAP has been used as a Silverlight Web Part in SP2010, the HTMLplaceholder portion of the display no longer scrolls with the rest of the page.  What am I missing?

12/16/2010 Update:  I have tried this with the HTMLplaceholder

• in the Main.xaml
• in a seperate user control, added to the Main.xaml by ContentPresenter
• using RadDocking
• using RadWindow

All versions present the same floating HTMLplaceholder content.  I've attached screenshots to illustrate.

Hello Robert,

In SharePoint the default style of the page is defined in the corev4.css file.
It defines the following styles that have to be modified in order to allow you to move the HtmlPlaceHolder with the page ScrollViewer:

body.v4master{
height:100%;
width:100%;
overflow:auto;
}

body #s4-workspace{
overflow:inherit;
position:relative;
left:0px;
}

You can find the modified file attached for further reference. I hope this info will help you.

We have the same problem, but this solution don't fit our needs. It changes the behavior of SharePoint 2010.

Hello Manuela,

I am not sure what you mean when you say that the solution changes the behavior of SharePoint 2010. Can you please elaborate on that?

Also, please keep in mind that the RadHtmlPlaceholder renders external pages in an IFrame positioned above the Silverlight plugin and therefore all styles applied on the page where the plugin is hosted affects the way the IFrame is renedered. So you can control the ScrollBars visibility mostly through styles.

The SharePoint 2010 Toolbar is scrolling out of the visible area in your solution. I don't want to explain, but this is realy bad. What i need to know is, will Telerik fix it,and when? Or should i find a solution by my self?

Hello Manuela,

RadHtmlPlaceholder renders external pages in an IFrame positioned above the Silverlight plugin and therefore all styles applied on the page where the plugin is hosted affect the way the IFrame is rendered. This is the reason why, we have little control over the way any external pages are displayed inside the HtmlPlaceholder.

And you can control the ScrollBars visibility/functionality mostly through styles. On our side the above suggestions worked as expected, although we will keep looking into other solutions to your scenario. However, it would be best if you check the style applied to the page where you add the Silverlight WebPart hosting the HtmlPlaceholder control and manage the overflow properties accordingly to the page's content and your requirements.
