Jiwa

I want to lock a sales order line from any editing.

I've tried the following but it doesn't work. Obviously removing the comments

Code: Select all

foreach (JiwaFinancials.Jiwa.JiwaSales.SalesOrder.SalesOrderLine line in salesOrderForm.SalesOrder.SalesOrderLines)
{
   if (!line.CommentLine && line.QuantityDemand > 0)
   {
      //salesOrderForm.grdLines.LockRow(line.ItemNo, true);               doesn't work
      //salesOrderForm.grdLines.ActiveSheet.ActiveRow.Locked = true;      doesn't work either      
   }
}

Any other tip?

That is because LockRow takes a first parameter of the row in the grid not the line item number, if you loop over the actual grid and then get the line by record id and get the value from the Key column and then check your conditions it will work below is how to get the key value.

What I am saying is the link between the lines and the grid is line's ID in the collection and the first hidden column in the grid where Jiwa puts the ID when it displays the lines. Jiwa does this for nearly all grids, you just have to work out what that first column is which you can usually find by looking at the setup function in the form.

Code: Select all

string LineID = salesOrderForm.grdLines.get_GridText("Key",row).ToString();


to get the line use

Code: Select all

SalesOrderLine line = salesOrderForm.SalesOrder.SalesOrderLines[LineID];


So what's the difference between your line

Code: Select all

SalesOrderLine line = salesOrderForm.SalesOrder.SalesOrderLines[LineID];

and my line?

Code: Select all

foreach (JiwaFinancials.Jiwa.JiwaSales.SalesOrder.SalesOrderLine line in salesOrderForm.SalesOrder.SalesOrderLines)

It's the same line isn't it?
The first parameter of salesOrderForm.grdLines.LockRow takes an integer.

There is no difference but if you use your for each loop you are then going to need a loop to roll over the grid inside it, basically you will end up with one loop if you look up the id of the line from the key column, below is the code for LockRow, the first value must be valid as the row you want to lock all it then does is go over the columns and locks the cells. The sales order line number also has nothing to do with the row number in the grid.

Code: Select all

        public void LockRow(int Row, bool LockValue)
        {
            IEnumerator enumerator = null;
            try
            {
                enumerator = ((IEnumerable)base.ActiveSheet.Columns).GetEnumerator();
                while (enumerator.MoveNext())
                {
                    Column current = (Column)enumerator.Current;
                    base.ActiveSheet.Cells[Row, current.Index].Locked = LockValue;
                }
            }
            finally
            {
                if (enumerator is IDisposable)
                {
                    (enumerator as IDisposable).Dispose();
                }
            }
        }


The sales order line number also has nothing to do with the row number in the grid.

OK. But then by that reasoning this should work. It doesn't.

Code: Select all

for(int row = 0; row <= salesOrderForm.grdLines.ActiveSheet.RowCount - 1; row++)
{
   salesOrderForm.grdLines.LockRow(row, true); 
}

Another important aspect is to where you are performing this locking of cells / rows.

We performing locking / unlocking of cells as part of the DisplayLine in the form - which is called in reaction to all sorts of events... and then permissions set might also lock grid columns.

Ahhh! That might be the hint I'm looking for! Cheers Mike.

Of course the other way of doing things would be to not lock the line but add a change event handler for the grid in the set up before handlers and simply tell the user they can't change the line and then simply client cancel exception and then Jiwa will never know the user did anything.

Not quite as elegant as locking the row but it would achieve what you need fairly simply.

I just remembered I had to do a slight of hand to let certain columns be editable on a snapshot greater than 1 adding a change event to grid behind Jiwa worked.

I can't see why doing the same to lock columns wouldn't work as easily as unlocking them

I think I have it sussed.....basically I reckon I've possibly determined that LockRow doesn't work. Might need more testing to check.

I need to use LockColumn and just specify each column, kinda like the plugin Sales Orders - Round Cash Sales to Nearest 5c.
In that plugin is

Code: Select all

   public void SalesOrderForm_LineDisplayed(object sender, System.EventArgs e, JiwaFinancials.Jiwa.JiwaSales.SalesOrder.SalesOrderLine SalesOrderLine, int Row)
   {
      JiwaFinancials.Jiwa.JiwaSalesUI.SalesOrder.BaseSalesOrderEntryForm salesOrderForm = (JiwaFinancials.Jiwa.JiwaSalesUI.SalesOrder.BaseSalesOrderEntryForm)sender;
      if (SalesOrderLine.PartNo == "ZRounding" && SalesOrderLine.NonStock)
      {
         for(int row = 0; row <= salesOrderForm.grdLines.ActiveSheet.RowCount - 1; row++)
         {
            if (salesOrderForm.grdLines.get_GridText("Key", row).ToString() == SalesOrderLine.RecID)
            {
               salesOrderForm.grdLines.LockColumn(true, "UnitOfMeasure", row);
               salesOrderForm.grdLines.LockColumn(true, "QuantityUnitOfMeasure", row);
               salesOrderForm.grdLines.LockColumn(true, "QuantityOrdered", row);
               salesOrderForm.grdLines.LockColumn(true, "QuantityBackOrdered", row);
               salesOrderForm.grdLines.LockColumn(true, "QuantityDemand", row);
               salesOrderForm.grdLines.LockColumn(true, "QuantityThisDelivery", row);
               salesOrderForm.grdLines.LockColumn(true, "SellPrice", row);
               salesOrderForm.grdLines.LockColumn(true, "PriceIncGST", row);
               salesOrderForm.grdLines.LockColumn(true, "ExtPrice", row);
               break;
            }
         }
      }
   }

so I just used that same concept & it seems to be doing what I was hoping.

EDIT: So I've done more testing. LockRow does work after all!
