This is my first time using DataGridView, and I've managed to solve most of my problems but one.In my datagridview table, I want the user to be able to add and remove rows as they please, they just select the row, click delete, and that row is goneMy problem is there is a row that is labeled the "new row" (i think?) that has an asterisk beside it(to the left) that will generate an error if you try to delete it.How do I remove the asterisk beside the row and make it so the row is deleteable by the user, and that it will not generate an error?Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")

You may want to use a For loop inside a For loop. Use a string to build each line of output before you send it to the ListBox. Your program should produce correct output even if the input is 0 or 1. Be sure to catch all exceptions and handle them intelligently. After this step, your program window should look like this.
NOTE: I had some trouble getting the desired output for the 10 and 4 user inputs to print out right... Rather than there being 2 rows next to each other, they should be spread apart by the number of asterisks on the top (and bottom...) thus creating the "asterisk square".
