Webgrid 7 checkbox column type setting value, for all rows

The snippet you found is still using previous WebGrid reference. If you are using WebGrid 6 or 7, please use this snippet to achieve the same functionality:

function checkAll() {
    // get an instance of the WebGrid
    var grid = ISGetObject('grdObj');

    //Header processing
    var RowHeader = grid.RootTable.GetElement(WG40.COLHEADER, WG40.HTMLTABLE).getElementsByTagName("tr")[0]
    RowHeader.getElementsByTagName("td")[1].getElementsByTagName('input')[0].checked = true;
    
    // collect all checkboxes
    // get all rows element of the WebGrid
    var rows = grid.RootTable.GetElement(WG40.BODY, WG40.HTMLTABLE).getElementsByTagName("tr");

    // iterate through all rows
    for (var i = 0; i < rows.length; i++) {
        if (rows[i].type == "Record") {
            // get the first column of the current row (checkbox)
            var cell = grid.GetRowByElement(rows[i]).GetCell(0).CellElement;
            cell.childNodes[0].checked = true;
        }
    }
}

I also attached a sample that I used to test the snippet.

Webgrid 7 checkbox column type setting value, for all rows

Hello,

I'm looking for setting all checkbox values (on my first column - column type checkbox).

I would like to do that client-side and I'm using JavaScript. I found a sample "Using Checkbox combined with client-side programming" :

function selectAll()
{
    // get an instance of the WebGrid
    var grid = wgGetGridById("WebGrid1");
    
    // collect all checkboxes
    // get all rows element of the WebGrid
    var rows = grid.Tables["Categories"].gettbTBElement().rows;
    
    // iterate through all rows
    for (var i=0; i< rows.length; i++)
    {
        if (rows[i].type == "Record")
        {
            // get the first column of the current row (checkbox)
            var cell = wgGetCellByPosition(rows[i], 0);
            cell.childNodes[0].checked = true;
        }
    }
}

All this function work well except the cell.childNodes[0].checked = true instruction. I get an error "childNodes.0" is null or not an object...

Do you have any ideas ?
