معلش يا غالى عايز تعمل الفاصل بين العناصر هذه العلامة |

انا حاولت ولكن ظهرت نفس المشكلة

Sub savedata(ByVal dg As DataGridView, ByVal filename As String)
Dim mList As New List(Of String)
For Each mRow As DataGridViewRow In dg.Rows
mList.Add(String.Join("|", From mCell In mRow.Cells Select mCell.Value))
Next
Dim mSB As New System.Text.StringBuilder
For Each mItem In mList
mSB.AppendLine(mItem.Replace("|", vbBack))
Next
IO.File.WriteAllText(filename, mSB.ToString)
End Sub


Sub loaddata(ByVal filename As String, ByVal dg As DataGridView)
For Each mLN As String In IO.File.ReadLines(filename)
Dim mList As New List(Of String)
For Each mItem In mLN.Split("|")
mList.Add(mItem.Replace(vbBack, "|"))
Next
dg.Rows.Add(mList.ToArray)
Next
End Sub

يريت تعدله انه يضيف العنصر كما كان

يعنى لو كان العنصر الاول مثلا 5 سطور
يبقا عند استدعاء الملف
يتم اضافة ال5 اسطر للعنصر الاول كما كان

وهكذا

معلش انا عارف انى تعبتك معايا

جعله الله فى ميزان حسناتك
