Scrolling two grids

[Dmitry]

I have a scenario where i have two grids side-by-side in my WPF app and as i scroll one grid id like to scroll the second one to keep in sync. both grids will contain one column that will have a matching key.

how can i accomplish this?

Hello Dmitry,

I am sending you a sample that demonstrates how you can sync two grids.

This is a very interesting example, thank you, it does do the basics of what I need.

The only concern I have is what happens when one of the grids is sorted. Id need to keep the grids in sync then by a key value (which will be the only thing matching between them) and not an exact visual position. I have some ideas but I welcome more suggestions.

Hi I am having some trouble using this in .Net 4. I have Q3 2011 SP1 Installed, Have you disabled this feature ?

[Kristjan Einarsson]

To be more precise I get this error:
'Telerik.Windows.Controls.RadGridView' does not contain a definition for 'ItemsControl' and no extension method 'ItemsControl' accepting a first argument of type 'Telerik.Windows.Controls.RadGridView' could be found (are you missing a using directive or an assembly reference?)

Hello,

You can use ChildrenOfType<T> extension method and find the required ScrollBar-s and GridViewScrollViewer-s. I am attaching the updated sample with binaries from our current official release.

Works like a charm, thank you.

ps. do you have any tips if on of the grids has two more columns that are frozen,, or will that always be a problem ?
Thanks again

Hello,

Could you clarify a bit - what is the exact behavior that you require in case there are frozen columns ?

Hi again,
Yes, in the grid with the frozen columns has two more columns so the two grids don't scroll at the same pace
Example
grid 1
frozen1| frozen2|Col1|Col2|Col3......
grid 2
Col1|Col2|Col3......

So my temp solution for now is to put two columns in the grid 2 with an empty header and freeze them, then put width on those frozen columns, that way I get the same scroll for both grids..... I was just wondering if there is any other way to accomplish that ? Otherwise this works well.

Cheers

Hello,

I believe such functionality cannot be easily supported since the width of the columns needs to be calculated, the speed of scrolling as well. 
Nevertheless, I am happy to see that you find a proper solution for your specific scenario that fits your current requirements.
