I have a checkboxcolumn as defined below:
<eo:CheckBoxColumn Width="50" HeaderText="<input id='CheckboxDeleteAll' type='checkbox' onclick='ToggleCheckboxes()' />"></eo:CheckBoxColumn>
In the 'ToggleCheckboxes() function, how do I access all the checkboxes in the grid to select and deselect them?

Hi, You won't be able to access the checkboxes directly. You would access the grid cell and uses interface on the cell object to check/uncheck the checkboxes. This is necessary so that the Grid can properly update its internal data. The code will be something like this:
Code: JavaScript
var grid = eo_GetObject("Grid1");
for (var i = 0; i < grid.getItemCount(); i++)
{
var item = grid.getItem(i);
//This assumes the checkbox column is the first column
var cell = item.getCell(0);
//"1" = checked, "0" = unchecked
cell.setValue("1");
}
Thanks!

Great, thanks.
Is there a way to get the value from the checkbox in the header?

Hi,
You would use regular JavaScript/DOM to access it. The checkbox in the header is not managed by the Grid thus really has nothing to do with the Grid.
Thanks!
