الحمدلله تم المطلوب باستخدام نفس التصميم وكله الشغل ع الأكواد

هذه الطريقة استخدمتها
private void btn_uni1_Click(object sender, EventArgs e)
{

grbox_Uni_Collage.Visible = true;
grbox_Uni.Visible = true;
cmbox_Uni_Name.DropDownStyle = ComboBoxStyle.DropDown;
txt_Uni_Note.Enabled = true;
grbox_Collage.Visible = false;
grbox_Specilization.Visible = false;
g = 1;
}

private void btn_collage2_Click(object sender, EventArgs e)
{


grbox_Uni_Collage.Visible = true;
cmbox_Uni_Name.DropDownStyle = ComboBoxStyle.DropDownList;
grbox_Uni.Visible = true;
txt_Uni_Note.Enabled = false;
grbox_Collage.Visible = true;
cmbox_Collage_Name.DropDownStyle = ComboBoxStyle.DropDown;
grbox_Specilization.Visible = false;
g = 2;
}

private void btn_specilization3_Click(object sender, EventArgs e)
{
grbox_Uni_Collage.Visible = true;
grbox_Uni.Visible = true;
txt_Uni_Note.Enabled = false;
cmbox_Uni_Name.DropDownStyle = ComboBoxStyle.DropDownList;
grbox_Collage.Visible = true;
cmbox_Collage_Name.DropDownStyle = ComboBoxStyle.DropDownList;
grbox_Specilization.Visible = true;

g = 3;
}
