What is with perfomance of RadGridView?

[Anton]

Hello.

We are use RadGridView (2018.1.116.45). We have RadGridView, which contains 1-100 rows and 10- some thousand columns. Data update is very slowly and interface is slows down when splitter (horizontal or vertical) is uses. What is a problem? where is "RadGridView for WPF is the ultimate grid control that provides outstanding performance" ?

Hello Anton,

I've tested the control with 100 rows and 10k columns and it was working pretty smoothly. Especially for an items control with 1 million data cells. You can check the attached project and let me know if I am missing anything.

Also, the RadGridView provides an outstanding performance in a big variety of different scenarios and setups. However, as the control tries to incorporate also a rich set of features there could be several cases where the performance may not be as fast as in the most generic setup.

For even better performance, you can take a look at the RadVirtualGrid control. The control rendering is optimized as much as the WPF framework allows, but this comes at the cost of many missing features. The control is very suitable for displaying and editing text based values in very huge amounts. You can see this in its Scrolling 1 Trillion Cells demo.
