In DGV, I have 2 checkbox columns. Column1 and Column 2. Once I checked a checkbox in a column and it happens that there is already a checked checkbox in the other column and they are in the same ROW. It will automatically disable/uncheck the Checked Checkbox.. Meaning only One CheckBox must be allowed to be marked if happens that they are in the same row.

I'm maintaining a Master Table call "MaterialList" in Datagridview Windows Form now I want to ADD Expandable row option to that Datagridview.
For your information : MaterialList Table is link to MaterialSales Table with Primary Key MaterialCode. By the way if I click any item of MaterialList the Sales Details should appear in that GridView. I'm using Visual Basic 2010 and Database SQLServer.
I would like to create a DataGridView that displays records that fill either 18 or 35 columns. I would like to avoid displaying all 35 columns for all records, instead showing the 17 extra columns on a second row for records that need them.How would I go about this? I'm guessing I need to create a new class that inherits from DataGridViewRow and override it's Paint or PaintCells method, but I have no experience with overriding Paint events, so I'm kind of lost after that.

I have searched the forums for an answer to this problem and while I have found simalar issuses, I have not found a solution that works for me. I have created a dataset and populated it. I know that this is true because I can view the information in the dataset in other ways such as using labels or textboxes. However to display the data in a organized and usable way I would like to display the information in a DataGridView control. I DO NOT need to be able to modify or add anything to the datagridview, JUST view the information there. I am not using any wizards to complete this and so I need to be able to complete everything programmaticly. I have written the code involved to the best of my understanding. When I run the application, there are no crashes or errors thrown, I just can't get the datagridview to populate. Below is the code that I am currently using:
[Code]...
I try to select the last row like this:
Dim lastRow As Integer = DGV.RowCount
MsgBox(lastRow)
DGV.Rows(lastRow).Selected = True
The messagebox returns the correct number, but when it comes to select that row it says:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
But if I assign it a row, example: DGV.Rows(5).Selected = True
My code works fine but what I'm trying to do is bind the data without it inserting the column names in the mysql table.[code]
