Formula Calculation

[Greg Wright]

I am having a problem with a formula calculating after I insert a column (using InsertRange). Even if I reset the formula, it still won''t work. The attached sample shows an example. When the form first loads, the formula works fine. If the button is clicked (which adds a column using InsertRange), the value of the formula cell doesn''t change when any of its dependent cells is changed. Am I doing something wrong, or is this a DirectTrac issue? FYI: I am running 1.6.1. Thanks, Greg GridFormulaTest_2962.zip

Do I need to call ResetFormulaTag()?

In 1.6.1, resetting the formulatag does seem to avoid the problem. In 2030, you can clear a couple of hashtables and recalculate things without having to visit each cell trying to reset the formulatag.

Here is code that seemed to avoid teh problem in 1610 for me.

this.gridControl1.Model.Cols.InsertRange(this.FormulaCol, 1);
this.gridControl1[1,4].ResetFormulaTag();
