Net datagridview rowvalidating
I want my users to enter some data into a bound Data Grid View (dgv) and when done to have the program fill in some columns (hidden key) and to populate some cells in the same row according to the data entered - like max of several cells.
Can I use Data Grid View Row Validating to update cells? What would be the correct way for me to fill in hidden key information and to calculate some cell values?
You can use a Data Grid View Combo Box Column to act a as "look up table" to show a user friendly version of the field, rather than just a numeric equivalent.
It is enabled in a text box column to enter only non-empty strings. Cell Validating Event Args) Handles Rad Grid View1. For example, if a user types in alpha characters (like "abc") into a numeric field, a data conversion error occurs before Row Validation.In this case we need a "global" error checker to detect data conversion errors.You can handle this case by subscribing to the Data Error event.
In the Grid View Data Error Event Args you have access to the row/column index and the exception. Dim index As Integer ' find the location of the column index = Data Grid View1. Name = "Category" ' the column name (and heading) dgvc.
