How to check the checkbox on group header row?

[Thanh]

Hello,

I'm using Telerik version 2017 R2 for Winform app.

I have a gridview with "EnableHeaderCheckBox" option is "True".

When I group the gridview by a column A, then click on the checkbox on gridview header row (I meant "Select All" checkbox), please see the picture 1 below

[Picture 1] Click on Select All checkbox

[Picture 2] The result of click on Select All checkbox

As you can see in the result (Picture 2), the checkboxes of group header row is not checked automatically. When I click on the Select All checkbox, it just affects to the children checkboxes in each groups, not the checkboxes on group header row.

How can I check all the checkboxes on group header row when I click on the Select All checkbox?

Please give me an advice! Thanks so much!

Hello Thanh,

You need to subscribe to the RowsChanged event and update all rows. I have attached a project that shows this.

I hope this will be useful. Let me know if you have additional questions.
