当我试图手动插入所需的字段验证器时,我需要字段验证器。当我删除所需的字段验证器时,有人能告诉我发生了什么吗?首先,您需要在gridview上实现事件以启用编辑,MSDN定义: 在单击行的“编辑”按钮时发生,但在 GridView控件进入编辑模式 ASPX:
<asp:GridView
ID="gvCustomers"
runat="server"
OnRowEditing="gvCustomers_RowEditing">
protected void gvCustomers_RowEditing(object sender, GridViewEditEventArgs e)
{
gvCustomers.EditIndex = e.NewEditIndex;
//Re bind the grid view
}
现在,如果在网格视图上单击“编辑”链接时未触发此事件,则表示页面上存在阻止回发的验证逻辑
解决此问题的最佳方法是为导致问题的验证控件(而不是gridview)设置ValidationGroup
属性:
<div id="insertEmployee">
<asp:TextBox ID="txtName" runat="server" ValidationGroup="Insert" />
<asp:RequiredFieldValidator ID="rfvName" runat="server" ControlToValidate="txtName" ErrorMessage="Name is required" ValidationGroup="Insert" />
<asp:Button ID="btnAdd" runat="server" Text="Add" ValidationGroup="Insert" />
</div>
