[英]Repeater's Item command event is not firing on linkbutton click
I am having problem with my repeater's OnItemCommand event. 我的转发器的OnItemCommand事件有问题。 When I click the Link Button, its not firing.
当我单击链接按钮时,它不会触发。 Am I missing any environment variable

<table>
<!-- repResearchers begin, 0=display name, 1=url -->
<asp:Repeater ID="repExtResearchers" Runat="server" OnItemCommand="deleteResearcher">

protected void deleteResearcher(object sender, RepeaterCommandEventArgs e)
{
string a;
lblError.Text = e.CommandArgument.ToString();
lblError.Visible = true;
}
Make sure you dont rebind the repeater at every postback. 确保你不要在每次回发时重新绑定转发器。
If (Page.IsPostBack)
return;
repExtResearchers.DataSource = ...
repExtResearchers.DataBind();
Hope that helps. 希望有所帮助。
I'm sure - as this is an EXTREMELY old question - that this has been answered already, but for people who may be running into what I was running into... 我敢肯定 - 因为这是一个非常古老的问题 - 这已经得到了回答,但对于那些可能遇到我遇到的问题的人来说......
If you're using any of the Ajax Controls, they all require a validation group. 如果您使用任何Ajax控件,则它们都需要验证组。 I had a really long page that I was trying to shorten by doing this, so I wasn't noticing that the ajax controls from the Ajax Control Toolkit were throwing errors and not validating.
我有一个很长的页面,我试图通过这样做缩短,所以我没有注意到Ajax Control Toolkit的ajax控件抛出错误而没有验证。 I set the LinkButton's validation group to something that was nowhere anywhere and it started firing.
我将LinkButton的验证组设置为无处可寻的东西,并开始触发。
Hopefully, that helps someone out. 希望,这可以帮助某人。
I had this issue using OnCommand
in a LinkButton
and I had an empty href=""
. 我在
LinkButton
使用OnCommand
遇到了这个问题,我有一个空的href=""
。 When I removed the extra attribute, it posted back. 当我删除额外属性时,它会回发。
It won't fix your ptoblem but change 它不会修复你的问题而是改变
OnClientClick="if (!confirm('Are you sure do you want to delelte it?')) return false;"
to 至
OnClientClick="return confirm('Are you sure do you want to delelte it?')"
Your code is using a double negative to confirm a positive. 您的代码使用双重否定来确认肯定。
