Introduction

Many of you have noticed that RadGridView has MasterTemplate and MasterView of types GridViewTemplate and GridViewInfo, respectively. The aim of this article is to explain what these properties are.

Explanation

One GridViewTemplate corresponds to one DataSource. As its name speaks, it is a template and it defines the structure of the data presented - the number, order, header text and other properties of the columns. In addition it has properties for user interaction - AllowAddNewRow, ShowColumnHeaders, etc.

On the other side, you may have several GridViewInfo's (views) for one DataSource. In a RadGridView displaying flat data, there is one *GridViewTemplate *and one *GridViewInfo *for one DataSource. Therefore, you will find that some of their properties will return one and the same values.

In order to understand the actual difference, let's analyze the case of hierarchical grid with 2 levels of hierarchy - one parent and one child levels. Since there are two DataSources in this case, there are two GridViewTemplates - one per level. These GridViewTemplates govern the data structure properties.
However, you may have several GridViewInfos for one GridViewTemplate - if you have three rows of the MasterGridViewTemplate expanded, you will have three GridViewInfos for the child GridViewTemplate.
