Display visible rows

[Pavel Ruslanovich Kovyev]

Добрый день.

Использую RadGridView, данные получаю при помощи ItemSource из коллекции элементов. Строчки грида можно сгруппировать и свернуть  так, как показано во вложенном рисунке.

Как мне определить какие строки видны, а какие свернуты? Т.е. найти элементы из коллекции, которые в гриде видны.

Good afternoon.
I use RadGridView, data obtained using ItemSource from the collection of elements. Grid Lines can be grouped and collapse as shown in the attached picture.
How can I know which rows are visible and which are rolled? How can I find items from the collection, which in the grid visible.

Hi Pavel Ruslanovich Kovyev,

This way you can find the rows visible at the moment ( the ones in the viewport) .

var rows = this.RadGridView1.ChildrenOfType<GridViewRow>();
*To have access to the ChildrenOfType  method you will need to add a  using Telerik.Windows.Controls;

*Please have in mind that in the collection returned the the first element would be a special row ( GridVIewNewRow ) which you may need to skip.

This way you have the rows visible. To have the data items associated with these rows  - you need read the Item property of the row , or its DataContext.
