View 1 RepliesDataGridView: Validation On Keystroke In Column (D.G.V.TextBoxColumn)?
Jan 18, 2009I was curious if there is an easy way, besides making a new custom DataGridViewColumn, that on each keystroke validation is done (while the D.G.V.TextBoxCell is being edited), instead of when focus is lost off the cell.Or in a different senerio, if there is a way to restrict user keystrokes while a D.G.V.TextBox Cell is being edited, while not relying on making a new custom DataGridViewColumn. I would go through the work of implementing this new Column, except the customer for the job I am working at wants small, managable code. And even if this is a useful feature, they would want to avoid having an extra class being made.

Decimal Column In Datagridivew Is Not Sorting Numerically?
Mar 16, 2012I have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?

When Adding A Value To Another Value The Results Eventually Change From 2-decimal Places To Multiple Decimal Places?
Mar 13, 2009Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.

New Withheld Amount = 710.79
Running total = 330141.54

As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..
