我一遍又一遍地收到这个错误.
将数据加载到GridView中起作用,但是当我想删除一行时,我会收到该错误.
<asp:GridView ID="OrdersGridView" runat="server" AutoGenerateColumns="False" onrowdeleted="OrdersGridView_RowDeleted">
<Columns>
<asp:TemplateField HeaderText="Product Name">
<ItemTemplate>
<asp:HiddenField runat="server" ID="HiddenField1" Value='<%#Eval("oid")%>'></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="titel" HeaderText="Name" />
<asp:BoundField DataField="oid" HeaderText="Itemno" />
<asp:BoundField DataField="prijs" HeaderText="Price" />
<asp:CommandField ButtonType="Link" CausesValidation="false" HeaderText="Update" ShowDeleteButton="True" />
<asp:BoundField DataField="prijs" HeaderText="Subtotal" />
</Columns>
</asp:GridView>
C#codebehind – 我不是真的从数据库中删除行,但它是一个测试：
protected void OrdersGridView_RowDeleted(object sender,System.Web.UI.WebControls.GridViewDeletedEventArgs e)
{
if (e.Exception != null)
{
lblStatus.Text = e.Exception.ToString();
}
else
{
string sValue = ((HiddenField)OrdersGridView.SelectedRow.Cells[1].FindControl("HiddenField1")).Value;
lblStatus.Text = sValue;
}
}
但点击后,我得到一个bigass黄页与下一个错误：
The GridView ‘OrdersGridView’ fired event RowDeleting which wasn’t handled.
解决方法
删除按钮,甚至是具有CommandName的删除的GridView中的常规按钮,将自动尝试启动OnRowDeleting.你可以添加它来使事情变得快乐,但不要做任何事情,所以它不会影响你的删除行为.
您可以将OnRowDeleting添加到GridView中：
<asp:GridView ID="OrdersGridView" runat="server" AutoGenerateColumns="False" onrowdeleted="OrdersGridView_RowDeleted" OnRowDeleting="OrdersGridView_RowDeleting">
然后在你的CodeBehind中添加：
void OrdersGridView_RowDeleting (object sender,GridViewDeleteEventArgs e)
{
}
