View 5 RepliesDataGridView Update Is Ok, Second Update Fails
Feb 13, 2011I am beginning to work with .NET technology after several years of VB6 and C++ and I want to learn as fast as possible.
My problem is with a DGV. It shows the prices of several store items, and I intend to let the user modify those prices by entering a % in a textbox (radio button states if that % is positive or negative) or by editing cell by cell manually.
As editing prices is kind of sensitive, what I do is loop through the DGV, add or substract the % engtered in the corresponding column and ask for a confirmation after whole DGV loop is done. If user agrees, DB is updated with new values. No problem here.
If user denies (in case he/she made a mistake), I restore grid's DataSource to a copy I made before calculating new percentages and this automatically refreshes my grid to its original state.
The issue is that if a user denies the operation for a 2nd time, this 2nd execution of the code fails at showing the original values, disabling the pseudo-rollback function.
Here is the code:

Unable To Get DataGridView Row Color?
Feb 23, 2012My application uses 3 DataGridViews in asingle Windows form. The 3 are never visible at the same time, and I have a sityation that I cannot figure out. The first examole below works perfectly:
For Each row As DataGridViewRow In dgvBooks.Rows
If row.Cells(4).Value.ToString = "YES" Then
row.DefaultCellStyle.ForeColor = Color.Red
[code]....
The only difference in the 2 blocks of code is the name of the DataGridView. I'm at a complete loss to figure out why one works completely and the other only partially. I have checked the execution, one step at a time and everthing happened at the right time and accurately, The upper case string is correct as is rhe index designation of the field, and I'm lost for a reason.
