请建议该怎么做。我没有线索。源对象就是触发命令的对象。只需将源代码转换为图像按钮,然后检查按钮是1还是2
protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
{
ImageButton imgBtn1 = e.item.FindControl("imgBtn1") as ImageButton;
ImageButton imgBtn2 = e.item.FindControl("imgBtn2") as ImageButton;
}
更新
由于上面的代码不起作用,请尝试以下方法:
protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
{
ImageButton fired = source as ImageButton;
if(fired!=null && fired.Id=="imgBtn1")
{
//imgBtn1 fired the command
}
else
{
// and so on...
}
ImageButton imgBtn1 = e.item.FindControl("imgBtn1") as ImageButton;
ImageButton imgBtn2 = e.item.FindControl("imgBtn2") as ImageButton;
}
您是否尝试将命令名应用于图像按钮
<telerik:GridTemplateColumn UniqueName="TemplateColumn">
<ItemTemplate>
<asp:ImageButton CommandArgument="btn1" ID="imgBtn1" runat = "server"/>
<asp:ImageButton CommandArgument="btn2" ID="imgBtn2" runat = "server"/>
</ItemTemplate>
</telerik:GridTemplateColumn>
protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
{
if(e.CommandArgument=="btn1")
{
//imgBtn1 fired the command
}
else if(e.CommandArgument=="btn2")
{
//imgBtn2 fired the command
}
ImageButton imgBtn1 = e.item.FindControl("imgBtn1") as ImageButton;
ImageButton imgBtn2 = e.item.FindControl("imgBtn2") as ImageButton;
}
我不熟悉telerik控件,但我很确定您要做的是为每个按钮指定ItemCommand
属性,然后GridCommandEvent
将有一个相应的属性,告诉您单击了哪个命令。Icarus:-它的给定错误-->'fired'为空。我只点击了上面提到的一个项目按钮,而不是其他任何东西。可能是什么问题>??@Kings尝试在每个图像按钮上设置CommandArgument属性,并检查e.CommandArgument以查看是否触发了btn1或btn2。将编辑我的答案,看看这是否有帮助。“CommandName”属性在更简单的意义上对我有效。但我花了时间试图理解你的第二种方法。这一点稍加修改就行了。非常感谢您这么多的努力。@Kings,很高兴它能帮上忙:)
