我正在尝试处理按下按钮字段中的按钮的事件,然后从网站和数据库中删除该行。我这样做但在我的.aspx.cs文件中使用以下代码:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
System.Diagnostics.Debug.WriteLine("testing buttons");
}
}
但是,每当我单击按钮字段中的按钮时,它都会抛出错误,指出未处理该事件。以下代码是整个数据表的aspx。
<asp:GridView ID="gridViewStudent" runat="server" CellPadding="4" ForeColor="#333333"
emptydatatext="There are no data to display">
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:ButtonField ButtonType="Button" CommandName="Delete" HeaderText="Edit" ShowHeader="True" Text="Remove" />
</Columns>
<EditRowStyle BackColor="#2461BF" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#EFF3FB" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#F5F7FB" />
<SortedAscendingHeaderStyle BackColor="#6D95E1" />
<SortedDescendingCellStyle BackColor="#E9EBEF" />
<SortedDescendingHeaderStyle BackColor="#4870BE" />
</asp:GridView>
答案 0 :(得分:0)
从我看到的情况来看,你并没有向GridView
声明所有必需的事件处理程序。对相应的操作使用适当的事件处理程序和事件处理程序方法:
页面标记(ASPX)
<asp:GridView ID="gridViewStudent" runat="server" ...
OnRowCommand="gridViewStudent_RowCommand"
OnRowDeleting="gridViewStudent_RowDeleting">
</asp:GridView>
代码落后(ASPX.CS)
// Row command event
protected void gridViewStudent_RowCommand(object sender, GridViewCommandEventArgs e)
{
// do something
}
// Row deleting event
protected void gridViewStudent_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
// do something
}
