执行数据库更新后，您不会重新绑定数据。

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();
    }
}

BindData是您检索数据的地方：

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