Prevent Editing In WebGrid Child Row Based On Value In Parent Row

To accomplish this, handle the BeforeEnterEditMode client-side event. Depending on the value of the parent row we can either cancel the event or allow it to continue.

Example flow in pseudo-code for this implementation:
1. Is the row a child row? If so, we should check the value of one of the cells on the parent; if not, allow editing as normal.
2. Examine the Value of a boolean cell in the parent row.
3. If the Value is false, then cancel the event, so that edit mode is never entered.
4. If the value is true, allow editing as normal.

In JavaScript:

function UltraWebGrid1_BeforeEnterEditModeHandler(gridName, cellId)
{
var oRow = igtbl_getRowById(cellId);

if ((oRow.ParentRow != null) && (oRow.ParentRow.getCell(3).getValue() == false))
{
// Return true to cancel the event.
return true;
}
else
{
// Return false to let processing continue uninterrupted
return false;
}
}
