Hello 
I have used the same approach mentioned here a solution by @Ben where I want to triger a client action when the user select the checkbox from the grid, it works fine for me the good part, But when ever I try to navigate to another page it gives me the following error, let me know if we can fix this

I am attaching the Oml file that might helpWhat I am trying to do is,1) I wan to capture the ID's on a on change of a check box,  I will get the Id of the selected checkbox

2) I have added the JS and used it on a Oninitilize of grid handler



Thanks & Regards

Hello @Tousif Khan 

I also did a small change to make it more performant using the following script:


OutSystems.GridAPI.GridManager.GetGridById($parameters.GridWidgetId).rowMetadata._grid._rows._g.onSelectionChanged = function(e) {
    var currentRowIndex = e.row;
    var currentRow = e._p._rows[currentRowIndex];
    
    //use col position to only trigger in the checkbox
    if(currentRow && e.col === -1){
        if(currentRow.isSelected) {
            $actions.SelectedIds(false,currentRow.dataItem.Employee_.Id);
        } else {
            $actions.SelectedIds(true,currentRow.dataItem.Employee_.Id);
        }
    }
    this.selectionChanged.raise(this, e);
}

Please check the oml attached on the screen DataGrid_Alternative.

Cheers,
GM

Hi Tausif,

The following minor changes to your script would fix this issue

GridAPI.GridManager.GetGridById($parameters.GridWidgetId).rowMetadata._grid._rows._g.onSelectionChanged = function(e) {
    var currentRowIndex =  e.row;
    var currentRow = e._p._rows[currentRowIndex];
    if(currentRow){
        if(currentRow.isSelected) {
            $actions.DeleteOnClick(true);
        } else {
            $actions.DeleteOnClick(false);
        }
    }
    this.selectionChanged.raise(this, e);
}
