单击编辑buitton时停止Gridview值更改

Question

我需要有关此Gridview问题的帮助。我在Gridview基础上根据ID构建下拉列表搜索，如下图所示

我遇到的问题是，当我单击“编辑”按钮更新Gridview时，Gridview的值会更改并返回到表格中的第一个值，如下图所示

C＃代码GridViewMYD88_RowUpdating

  protected void GridViewMYD88_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        GridViewRow row = GridViewMYD88.Rows[e.RowIndex];

        Label TestID = (Label)GridViewMYD88.Rows[e.RowIndex].FindControl("lblId");
        Label SampleBranchID = (Label)GridViewMYD88.Rows[e.RowIndex].FindControl("lblSampleBranchID");


        string TechniqueforMYD88  = (row.FindControl("txtTechniqueforMYD88") as TextBox).Text;
        string MYD88ExonsAnalyzed = (row.FindControl("txtMYD88ExonsAnalyzed") as TextBox).Text;
        string SequenceofEntireMYD88 = (row.FindControl("txtSequenceofEntireMYD88") as TextBox).Text;
        string MYD88MutationStatus = (row.FindControl("txtMYD88MutationStatus") as TextBox).Text;
        string NumberofMYD88Mutations = (row.FindControl("txtNumberofMYD88Mutations") as TextBox).Text;
        string MYD88pL265PMutation = (row.FindControl("txtMYD88pL265PMutation") as TextBox).Text;
        string OtherMYD88MutationDescription = (row.FindControl("txtOtherMYD88MutationDescription") as TextBox).Text;
        string MYD88VAFPercentage = (row.FindControl("txtMYD88VAFPercentage") as TextBox).Text;
        string MYD88RefAllelesReads = (row.FindControl("txtMYD88RefAllelesReads") as TextBox).Text;
        string MYD88VariantAllelesReads = (row.FindControl("txtMYD88VariantAllelesReads") as TextBox).Text;
        string MYD88OverallReadDepth = (row.FindControl("txtMYD88OverallReadDepth") as TextBox).Text;

        using (SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["Molecular"].ConnectionString))
        {
            con.Open();

            using (SqlCommand sc = new SqlCommand(@"UPDATE MutationResults

                            SET TechniqueforMYD88=@TechniqueforMYD88, MYD88ExonsAnalyzed=@MYD88ExonsAnalyzed, SequenceofEntireMYD88=@SequenceofEntireMYD88,

                             WHERE

                sc.ExecuteScalar();

            }
            con.Close();
        }


        GridViewMYD88.EditIndex = -1;
        this.BindGridMutationResults();
    }

任何帮助如何解决此问题。感谢
