Solution 2

save value of both combo box in a public String variable
Code on form1 where there are 2 combo box

VB

public strSource as string=""
public strDest as string=""

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

strSource =ComboBox1.Text

End Sub

Private Sub ComboBox2_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox2.SelectedIndexChanged

strDest =ComboBox2.Text
 
End Sub

Now on Form2 where there is DataGridView1 write below code on form2 load

VB

DataGridView1.Rows.Add(form1.strSource,form1.strDest)

i assume there are two coloums in DataGridView1
Happy Coding.....

Solution 1

Exactly how you do this depends to an extent on how you display the two forms.

If you create the Form2 and display it from your Form1 (on a button click for example) then you can either write a Form2 constructor that accepts the information as parameters and displays it, or you can add public properties to Form2 which display the information. You can then set the information when you create the instance, and before you call ShowDialog.

If you already have Form2 open, created and displayed (via the Show method) from Form1, then create the properties as above and use Form2 instance you displayed to set the display information via those.

If the Form2 is created outside Form1 (by a parent form for example) then the best way is to create an event in Form1 which tells the parent to get the info and pass it to Form2 (again via Form2 properties)
