gridview 更新不执行代码

Question

各位大侠，帮我看看，到底是什么状况..
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
                OnRowDataBound="GridView1_RowDataBound" 
                OnPageIndexChanging="GridView1_PageIndexChanging" 
                OnRowDeleting="GridView1_RowDeleting"
                OnRowCancelingEdit="GridView1_RowCancelingEdit" 
                OnRowEditing="GridView1_RowEditing" 
                OnRowUpdating="GridView1_RowUpdating" AutoGenerateColumns="False">
                    <Columns>
                    <asp:BoundField DataField="ClassifyID" HeaderText="一级主码"  ReadOnly="True">
                    <ItemStyle Width="18%" />
                    </asp:BoundField>
                    <asp:BoundField DataField="ParentID" HeaderText="二级子码" >
                    <ItemStyle Width="18%" />
                    </asp:BoundField>
                    <asp:BoundField DataField="ClassifyName" HeaderText="图块类别">

                    <ItemStyle Width="18%" />
                    </asp:CommandField>
                    <asp:CommandField HeaderText="删除" ShowDeleteButton="True"><ItemStyle width="10%" /></asp:CommandField>
                    </Columns>

        }
        catch (Exception err)
        {
            Response.Write(err.Message);
        }
    }
除了“更新”按钮点下去，一点反应也没有（GridView1_RowUpdating()，都不执行），别的都可以正常使用

Answer 1

 GridView属性加DataKeyNames="主键" 

Answer 2

public void Bind() 
    { 
        string strsqlcode;         strsqlcode = "select ClassifyID ,ParentID ,ClassifyName ,ClassifyMark from Gallery_Dwg_Dir"; 
        conn = new SqlConnection(strcon); 
        conn.Open(); 
        SqlDataAdapter dpart = new SqlDataAdapter(strsqlcode, conn); 
        DataSet dset = new DataSet(); 
        dpart.Fill(dset); 
        GridView1.DataSource = dset.Tables[0]; 
        GridView1.DataBind(); 
        GridView1.DataKeyNames = new string[] { "ClassifyID" }; 
        conn.Close(); 
    } 我上面是这样写的   应该怎么改么？

Answer 3

我也想调试啊，问题是  不管哪个做断点，点更新，都没动静    感觉就像，没给OnRowUpdating事件写代码一样  protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) 
根本没执行

Answer 4

你怎么调试的。
我没用过RowUpdating事件.
如果你调试正常就说明这个事件对UPDATE不起作用。
否则的话你调试方式错了，不太可能吧

Answer 5

好吧，我这样说吧：
我把这句删了  OnRowUpdating="GridView1_RowUpdating"  ，就是说，更新，按钮事件没定义。点击“更新”按钮也不会出错，就是没反应

Answer 6

 OnRowUpdating="GridView1_RowUpdating"这句删了？有反映才怪。还是调试吧

Answer 7

GridView“GridView1”激发了未处理的事件“RowUpdating”。  这应该是必须出现的啊？？
如果，都没有错误，我都不知道怎么调试了你教我下    我学asp.net 不久，都不怎么懂

Answer 8

GridView1这控件我也用的不熟。。
静待高人吧

Answer 9

NND  终于，弄出来了
经过，把里面的控件 一个个，排除。
终于发现，导致更新按钮的脚本不执行的原因是与“RequiredFieldValidator”验证脚本冲突
