Hello Vishnu,

I am still following up. Have you been able to resolve the issue?
If you have any concerns or questions, please feel free to contact me, I will be glad to help you.
Thank you for choosing Infragistics components!

Hi Vishnu,

This is what you need in order to have a checkbox in the header:

<ig:BoundCheckBoxField DataFieldName="OnSite" Key="OnSite">
    <Header Text="On Site <input type='checkbox' onchange='headerCheckedChangedHandler(this);'"></Header>
</ig:BoundCheckBoxField>

And the following is the code to check the boxes in the column:

function headerCheckedChangedHandler(checkbox) {
    var grid = $find("WebDataGrid1");
    var checkBoxState = checkbox.checked;
    var columnKey = checkbox.parentElement.getAttribute("key");
    var rows = grid.get_rows();
    // iterate through the rows and set the checkBox states and cell values
    for (i = 0; i < rows.get_length() ; i++) {
        var cell = rows.get_row(i).get_cellByColumnKey(columnKey);
        cell._setCheckState(checkBoxState);
        cell.set_value(checkBoxState);
    }
}

Since this is using a template it can be modified in a lot of ways, but also need to be handled manually.
