Question

我有一个gridview，每行都有一个编辑和删除按钮。我设法让我的编辑按钮工作，但没有设置删除按钮。这是我的aspx：

 VALUES
        (1, 1, convert(datetime,'2010-01-01'),0,10.0),
        (2, 1, convert(datetime,'2010-01-02'),0,11.0),
        (3, 1, convert(datetime,'2010-01-03'),10,12.0),
        (4, 2, convert(datetime,'2010-01-04'),0,12.0),
        (5, 2, convert(datetime,'2010-01-05'),10,11.0),
        (6, 2, convert(datetime,'2010-01-06'),10,13.0),
        (7, 3, convert(datetime,'2010-01-07'),10,14.0),
        (8, 3, convert(datetime,'2010-01-07'),10,16.0),
        (9, 3, convert(datetime,'2010-01-09'),10,13.0)

这是我背后的代码：

<asp:GridView ID="gvfaq" runat="server" AutoGenerateColumns="false" DataKeyNames="faq_id" OnRowDataBound="gvfaq_RowDataBound" OnRowCommand="gvfaq_RowCommand" OnRowDeleting="gvfaq_RowDeleting" >
        <Columns>
            <asp:BoundField ItemStyle-Width="100px" DataField="text" HeaderText="Text" />
            <asp:TemplateField HeaderText="">
                <ItemTemplate>
                    <asp:Button runat="server" ID="editbutton" CommandArgument='<%# Eval("faq_id") %>' CommandName="Edit" Text="Edit" />
                    <asp:Button runat="server" ID="delbutton" CommandArgument='<%# Eval("faq_id") %>' CommandName="Delete" Text="Delete" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

奇怪的是，我有另一个页面，从我复制/重新发布此代码的地方，并且工作正常。

感谢。

更新如果我检查在其他页面按钮上生成的html，则会添加此代码，但在此处不会成功：

protected void gvfaq_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Delete")
    {
        int ID = Convert.ToInt32(e.CommandArgument);
        DeleteFAQ(ID);
    }
}

protected void gvfaq_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Button l1 = (Button)e.Row.FindControl("editbutton");
        l1.Attributes.Add("onclick", "Javascript:suport(" + l1.CommandArgument.ToString() + ");return false;");
        l1.Attributes.Add("onClientClick", "Javascript:suport(" + l1.CommandArgument.ToString() + ");return false;");
        Button l2 = (Button)e.Row.FindControl("delbutton");
        l2.Attributes.Add("onclick", "javascript:return confirm('Are you sure you want to delete this record?')");
        l2.Attributes.Add("onClientClick", "javascript:return confirm('Are you sure you want to delete this record?')");
    }
}

protected void gvfaq_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    GridView gv = (GridView)this.FindControl("gvfaq");
    int ID = (int)gv.DataKeys[e.RowIndex].Value;
    DeleteFAQ(ID);
}

protected void DeleteFAQ(int ID)
{
    using (SqlCommand myCommand = new SqlCommand())
    using (SqlConnection myServerCreate = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ServerCreate"].ConnectionString))
    {
        myServerCreate.Open();
        myCommand.Connection = myServerCreate;
        myCommand.CommandText = "delete from faq where faq_id = " + ID;
        myCommand.ExecuteNonQuery();
    }
    ScriptManager.RegisterStartupScript(Page, typeof(Page), "Close", "__doPostBack('','Delete');", true);
}

在itemtemplate删除按钮中将命令名更改为“删除”，因为它当前不同

 <asp:Button runat="server" ID="delbutton" CommandArgument='<%# Eval("faq_id") %>' CommandName="Delete" Text="Delete" />

然后检查命令名

protected void gvfaq_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Delete")
    {
        int ID = Convert.ToInt32(e.CommandArgument);
        DeleteFAQ(ID);
    }
}

此外，如果您通过行命令事件处理删除功能，则无需在gvfaq_RowDeleting事件中明确地添加该功能。您应该将其保留为空白。

GridviewRowCommand没有触发
