编辑GridView时点击文本框弹出一个窗口。

function aa()
{
   window.showModalDialog("aa.aspx");
}
</script><asp:GridView ID="gvXGJL" runat="server" AutoGenerateColumns="False" PageSize="10"
Width="98%" AllowPaging="True" AllowSorting="True" DataKeyNames="ID" OnRowCancelingEdit="gvXGJL_RowCancelingEdit" OnRowDeleting="gvXGJL_RowDeleting" OnRowEditing="gvXGJL_RowEditing" OnRowUpdating="gvXGJL_RowUpdating"OnRowDataBound="gvXGJL_RowDataBound">

              <EditItemTemplate>
                   <asp:TextBox ID="TextBox1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Name")%>'Width="95%" ReadOnly="true" onclick="aa()"></asp:TextBox>
              </EditItemTemplate>
              <ItemTemplate>
                   <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
              </ItemTemplate>
         </asp:TemplateField>

Answer 1

我在RowDataBound这里面写也是不行的！

Answer 2

现在改了下代码
protected void gvXGJL_RowDataBound(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string _jsEdit = "showModalDialog('ChooseMaintenancePriceFrame.aspx?Cateogry=',null,'dialogWidth=650px;dialogHeight=500px;help:no;status:no')";
                TextBox TextBox1= (TextBox)e.Row.Cells[0].FindControl("TextBox1");
                if (TextBox1!= null)
                {
                    //这条OK
                    e.Row.Cells[0].Attributes.Add("onclick", _jsEdit );
                    //这条就不行了
                       e.Row.Cells[0].Attributes.Add("onclick", "aa()");                }
            }
}
真是很郁闷！

在RowDataBound里面写，好像还需要改那个属性才能生效
