Personalising kendoGridSelectAllCheckbox

[Emna]

I have a kendo-grid-checkbox-column that needs a checkbox in the header. When clicking on it, it' supposed to be a 

SelectAll checkbox there's a specific row i do'nt want to select.

First,  i thought i would just use:   

<ng-template kendoGridHeaderTemplate>   

<input  (click)="onclick( )"  type="checkbox"  >

</ng-template>

followed by an <ng-template kendoGridCellTemplate> 

 But, for unknown reasons, that made it impossible for me to select the other rows , as if they were disabled

Hi Emna,

Thank you for providing an explanation of the issue and a code snippet.

May I ask what was the code in the onclick handler? If you could fork the demo below and modify it to reproduce the undesired behavior, that would be great.

For the time being I can suggest using a CheckboxColumnComponent as seen in this demo:
https://stackblitz.com/edit/angular-fv6ud9?file=src/app/app.component.ts

This approach also has its limitations. For example, clicking the SelectAll checkbox twice, does not clear the selection. This is because if any row is not selected yet, the SelectAll checkbox selects our disabled row, "Chang", after which we immediately deselect it.

There are multiple ways of going about the problem, but it is important for me to understand what exactly the desired outcome it. For this reason I would like to ask what you would like to happen when the user clicks "select all" and then clicks on the row you don't want to select.

Should this row be selectable at all?

Looking forward to hearing from you.

Georgi
