Can you give us more information about the form? How is the Mark column bound? There is probably an edit method with a collection object in the form. So you will have to use that object to "mark" each row. By the way, please format your code by using Insert Code Snippet, it makes the code easier to read.

Thank you for your reply Anton,

The mark column is checkbox column and is not related to the datasource it is on the form level

----------------------------------------- class SelectAllButton { public void clicked() { MultiSelectionHelper selectionHelper = MultiSelectionHelper::construct(); super(); selectionHelper.parmDataSource(ModuleTable_ds); ModuleTable = selectionHelper.getFirst(); if (ModuleTable.RecId) { while (EX_ModuleTable) { info(strFmt("Selected record is %1", EX_ModuleTable.Module)); Info(int2Str(MarkedControl.value())); MarkedControl.checked(true); EX_ModuleTable = selectionHelper.getNext(); } } } } -------------------------------------------------- class ClearAllButton { public void clicked() { super(); while (ModuleTable) { Info(int2Str(MarkedControl.value())); MarkedControl.checked(false); } } }

Have a look at one of the standard forms like settling customer invoices to see how it's done.

But in the forms provided by Microsoft, there's a lot of functions inside each others, and it is too complicated, my idea is simpler than that, anyways thank you!

The basic idea is to bind your checkbox form control (dataMethod property) to an edit method on the form. The edit method uses a Map (with form scope) to store and retrieve the Marked values for each row in the grid. The map is used as form record cache. In the set part of the edit method, you set the current value of the Marked field using the key of the current record. In the get part, you retrieve the Marked value using the key from the Map.

The code below is untested and certainly not a complete edit method but it demonstrates the basic idea of what you should do.

NoYes ret; if (_set) { mMapMarked.insert(_table.RecID, _marked); } else { if (mMapMarked.exists(_table.RecID)) { ret = mMapMarked.lookup(table.RecID); } } return ret;
