Question

我有detailsview代码，用于更新单个字段的值。更新按钮我保持在页脚模板中。它在Visual Studio中完美运行，如果我发布到服务器并通过Url访问，页脚模板更新按钮是不可点击的。

请建议。

mycode的：＆lt;％@ Page Title =“”Language =“C＃”MasterPageFile =“〜/ RedTagMasterPage.master”％＆gt;

<script runat="server">

protected void BtnUpdate_Click(object sender, EventArgs e)
{  
    Label lblstatus = (Label)DetailsView1.FindControl("lblUpdateStatus");
    string Vname = DetailsView1.Rows[0].Cells[1].Text;
    TextBox NewQADNo = (TextBox)DetailsView1.FindControl("txtbxQADno");

    if (NewQADNo != null)
    {
      System.Data.SqlClient.SqlConnection myConnection;
      System.Data.SqlClient.SqlCommand myCommand;
       using (myConnection = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["MaterialsConnectionString"].ConnectionString))
       {
        string strUpdate = "UPDATE tblVendorMasterRegisteration SET QADVendorNo=" + NewQADNo.Text.Trim() + " Where VendorName ='" + Vname + "'";
        myCommand = new System.Data.SqlClient.SqlCommand(strUpdate, myConnection);
        myConnection.Open();
        myCommand.ExecuteNonQuery();
        myConnection.Close();

        lblstatus.Text ="Updated Successfully.";

        }
    }
    }

深入思考后，我开始知道风格定位给出了问题。 Detailsview Style =“position：relative; to Style =”position：center;

Detailview页脚模板按钮不可点击
