I have a mainForm with a DataGridView control. This DataGridView is not bound to any datasource. All Rows and Columns were added. On another Form, I have a button. When I click it I want the DataGridView to clear all rows.
Does not work, in button click event:
Form1.DatagridView1.rows.clear
Also does not work:
A "Public Sub" on the first form, invoked by the button press - so the change is made within the same form.
At runtime when the dgv is shown,then on clicking the header of a particular row of the dgv,i want to pop up a form...........how to do this?

I am using V Studio 2005, VB. In my application, I am asking the user to enter an ID and click on Search button. Now, when the user enter an ID for the first time, all the columns and rows appear fine in the DataGridView. When the user enters an ID second time (or third, etc), I want to erase the previous contents of the DataGridView and display the new values. For this, I am using .Clear() method of DataGridView which isn't giving me what I want. It is simply clearing the "previous values" and not deleting the "row".

If you want to replace this standard messagebox, handle the DataError-expection
When debugging, there is no break in the code. The messagebox just pops up without showing me exaclty where the error is located.
I am using TextFieldParser to read a .txt file and create a DataTable I then filter the table and create 4 new tables I then bind those tables to BindingSources Then Bind ComboBoxs to the BindingSource Then bind TextBoxes to BindingSource I like the user to be able to Open a new file without having to close the program So upon opening a new file I have a sub routine that clears the tables the rows and the columns of each table as well the DataBindings to each control The problem is once I do the Text Binding as such
Me.list1_MLStxt.DataBindings.Add("Text", Subject_Values.BindingSource1, Form10.mls_txt.Text)
Then when I open a new file I get an error message conversion from string"""" to type double is not valid.If I never perform the binding I can open and reopen different files without a problem. So this is causing me to think that the problem is with the way I am clear something? But I am obviously not sureIs there something I am missing to clear everything properly in order to open and read and bind a new file?

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")
