In the below case, the lnk_click doesn't fire.Do i need to remove the postback condition?I don't to load page everytime..
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server"><div><asp:LinkButton id="lnk" runat="server" OnClick="lnk_Click">click</asp:LinkButton>

I have the following image button:
<asp:ImageButton ID="submit" EnableViewState="true"
ImageUrl="/images/btn_submit.png" AlternateText="Submit" CssClass="f-right"
runat="server" onclick="submit_Click"></asp:ImageButton>
The event is fired in Firefox but not in IE*.
VWD 2008 Express. Visual Basic.
I noticed on a number of formviews that my validation controls seemed to be firing twice (which they were). I just found a case where a "Save" button had
onclick="UpdateButton_Click" in its defintion on the aspx page as well as the event routine having a "Handles UpdateButton.Click." This scenario made the UpdateButton_Click code run twice (and thus I expect that any validation controls would fire twice as well). When I removed the onclick="UpdateButton_Click"from the button defintion, the code only ran once, as desired. This double validation has gotten me especially with customvalidators.
Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
<my code>
End Sub
The question now is, why does having the onclick defined as well as the "Handles" on the event routine cause a double run of the event routine?I am going back into all my code to find where I have this "double" hit and remove the onclick in those instances.
I have a eventhandler in code behind of a UserControl.

I have a button on my webform which builds up a mailto: link, adding the email address, subject and body of the message. What I would like to do is be able to fire the link to open the user's default email client when the link has been built up. At the moment the best I can do is build the link and add it to the InnerHTML of a span, which means the user has to first of all click the button to create the link, then click the link itself. Is there a way to eliminate the second click and open the email client from the code behind?
View 2 RepliesI intend to record some information about my visitors and I will use code in master page to record it. The only missing element is to record user "exit". So I want to fire the code (sp) but with type "exit" when user either closes the browser or closes one of the tabs.
In the past I think I came across some that did that but I cannot find it.
I am after a reliable way to fire the sp and put it in the code in one place.

lets say I have a control with a button in it. I want to use my control on a page but then know when the button in the control has been clicked. I assume I need to fire some sort of event when the user clicks the button and then in my parent page I can hook into onMyCustomEvent or something..
How do I do this?

View 27 RepliesExample I have unsubscribed (is want to clear off the previous subscribed event) and subscribed the events every time when dataobject value has assigned:
_dataobject.OnQueryOpen -= new DataObject.On_QueryOpen(RefreshIGrid);
_dataobject.OnQueryOpen += new DataObject.On_QueryOpen(RefreshIGrid);
But, the RefreshIGrid still fired depend on how many times my dataobject has been assigned.
is it not really unsubscribed on what I have -= from the begining?

im using an update panel and my web form consists of textboxs and combo box, my problem is that when i click the button save for the first time, my page simply postbacks and the event save wouldnt fire, click it the second time and poof save will execute.. I notice that it is caused by my dropdown box and textbox autopostback function, i need to set this to true since i need to execute another function that will disable the dropdown when the textbox is filled and vice versa,set this to false and save will function normally..any ideas how to fix this?
here is the code for that.
<asp:DropDownList
ID="ddNewLocation"
runat="server"
Width="95%"
AutoPostBack="true"
AppendDataBoundItems="True"
onselectedindexchanged="ddNewLocation_SelectedIndexChanged">
<asp:TextBox
ID="txtNewLocation"
runat="server"
Width="90%"
AutoPostBack="true"
ontextchanged="txtNewLocation_TextChanged"></asp:TextBox>
In my default Page I register this listener:
[Code]....
and this Event is never fired
