[Solved] How to Customize PrintToHtml() of Silverlight RadGridview

[RAJIV]

Hi,

 

We are using the print feature of Silverlight RadGridview. Our gridview had a number of columns, and our requirement is to Print all the columns displaying on the Grid, but the function PrintToHtml()  is printing only 10 columns.

Is there any way we can customize the function for increasing the width of the Page or print all the columns displaying on the grid(such as 20 or 25)?

  
Thanks

Hello RAJIV,

 What version of RadControls for Silverlight are you using?

Thanks for reply.

The File version we are using is: 2010.2.917.1040

Hi RAJIV,

 PrintToHtml() is a legacy method. In this version you should use the code provided in our Printing demo, which allows you complete control over the printed GridView.

In the printing Demo how would you transfer the Groups IsExpanded property to the printed grid?

Hello MiddleTommy,

 The solution is not very straightforward, but it's doable.

1. In your source RadGridView, subscribe to the GroupRowIsExpandedChanged event. You need to add the Group of the expanded GroupRow in a list (and also remove the Group from the list when a GroupRow is collapsed).
2. Attach to the DataLoaded event of your printed RadGridView. In the handler you will need to iterate over all the IGroup objects you have gathered in the first step and find their counterparts in the printed RadGridView and expand them. Basically:

   foreach (var group in expandedGroups)
   {
       var printGroup = printedGridView.Items.Groups.OfType<IGroup>().Where(g => g.Key == group.Key).FirstOrDefault();
       if (printGroup != null)
       {
           printedGridView.ExpandGroup(printGroup);
       }
   }

Thanks that is awesome.
I would like to suggest for a future version that we store the IsExpanded information in IGroup or somewhere automatically.
Or that we have a method that can check if a group is expanded like so:

RadGridView.IsGroupExpanded(IGroup group)
//actually I like this better than storing it in IGroup.
