我用rowcommand
和rowarguements
在同一页面上创建了两个按钮,但是,只有其中一个工作正常,我不知道为什么当我试图点击另一个按钮时出现“意外错误”框。(btnInterview工作正常,btnContact
不管用)
不仅提示错误消息,btnContact
也无法在rowcommand
中触发事件。
下面的代码(.aspx部分):
<asp:GridView ID="GridView2" runat="server" AllowPaging="True"
EmptyDataText="No Sample is found"
OnPageIndexChanging="GridView1_PageIndexChanging"
PageSize="20"
OnSorting="GridView1_Sorting" OnDataBound="GridView1_DataBound"
OnRowCommand="GridView1_RowCommand" Width="100%" AllowSorting="True" OnRowCreated="GridView1_RowCreated">
<RowStyle HorizontalAlign="Center" VerticalAlign="Middle" />
<Columns>
<asp:TemplateField HeaderText="Phone Interview">
<ItemTemplate>
<asp:Button ID="btninterview" runat="server" Text="Interview" CommandName="btninterview_Click"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" CssClass="intBtn" />
<asp:HiddenField runat="server" ID="hidid" Value='<%# Bind("Id")%>' />
<asp:HiddenField runat="server" ID="hidProject" Value='<%# Bind("Project")%>' />
<asp:HiddenField ID="hidEnablebtn" runat="server" Value='<%# Bind("enableButton")%>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Phone Interview">
<ItemTemplate>
<asp:Button ID="btnContact" runat="server" Text="Contact" CommandName="btncontact_Click"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" CssClass="intBtn" />
<asp:HiddenField ID="hidVisibleBtn" runat="server" Value='<%# Bind("visibleButton")%>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
</asp:TemplateField>
</Columns>
</asp:GridView>
下面的代码(c#部分):
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e){
Button btn = (Button)sender;
switch (btn.CommandName)
{
case "btninterview_Click":
//do sth1
break;
case "btncontact_Click":
//do sth2
break;
}
}
您正在使用RowCommand
事件。在这种情况下,sender
不是Button,而是GridView本身。因此,当您尝试将GridView转换为Button时,您将获得Cast exeptions。你应该铸造CommandSource
。
Button btn = e.CommandSource as Button;
我希望你可以直接从GridViewCommandEventArgs本身获取命令名,如下所示,
switch (**e.CommandName**)
{
case "btninterview_Click":
//do sth1
break;
case "btncontact_Click":
//do sth2
break;
}
希望能帮助到你!
