Вы не подмена данных после того, как вы делаете обновление базы данных.

protected void GridView2_RowUpdating(object sender, GridViewUpdateEventArgs e) 
{ 

    DB_Function.OpenConniction(); 

string ExpID = GridView2.DataKeys[e.RowIndex].Value.ToString(); 

string CompNm = ((TextBox)GridView2.Rows[e.RowIndex].Cells[1].Controls[0]).Text; 
string JobTitel = ((TextBox)GridView2.Rows[e.RowIndex].Cells[2].Controls[0]).Text; 

string WorkPlace = ((TextBox)GridView2.Rows[e.RowIndex].Cells[3].Controls[0]).Text; 
string StartDate = ((TextBox)GridView2.Rows[e.RowIndex].Cells[4].Controls[0]).Text; 

string EndDate = ((TextBox)GridView2.Rows[e.RowIndex].Cells[5].Controls[0]).Text; 
string ReasonLeave = ((TextBox)GridView2.Rows[e.RowIndex].Cells[6].Controls[0]).Text; 

string CompPhone = ((TextBox)GridView2.Rows[e.RowIndex].Cells[7].Controls[0]).Text; 


    if(DB_Function.UpdateExperiance(ExpID)>0) 
    { 
     GridView1.EditIndex = -1; 

     lblState.Text = " Row is Updated "; 
     lblState.ForeColor = System.Drawing.Color.Blue; 

     BindData(); 
    } 
} 

Где BindData где вы получить ваши данные:

private void BindData() 
{ 
    GridView2.DataSource = (your data source); 
    GridView2.DataBind(); 
}
