.net - Verify Which LinkButton Is Clicked On A Page_Load?
Aug 23, 2010How do I check which LinkButton is clicked in the Page_Load of the page. This is to avoid calls to service so that it only executes what is present in its event.

View 5 RepliesI have a very common problem with asp.net . I have designed a webpage that performs some action on its load event but whenever a user clicks on back button those actions are not performed as Page_Load event is not called.I have searched a lot of forums but wasn't able to get a exact answer. All I was able to know that it was happening due to cache memory maintained by browsers. I don't want to delete that cache. I want browser to work in normal way.

<asp:LinkButton ID="LB1" runat="server" CssClass="regular" OnClick="LB1_Click">
Today</asp:LinkButton>

Today</asp:LinkButton>
<asp:LinkButton ID="LB3" runat="server" CssClass="regular" OnClick="LB3_Click">

I want to highlight a linkbutton on its click with a css and then remove its css when another linkbutton is clicked (ie) i want to show active link button.
I have discovered something strange when using a ListView. I have a listview contained inside an uodate panel and everything works OK until I edit the editItemTemplate to use a LinkButton instead of a Button.When i use a LinkButton then the Page_Load event is fired.
View 3 RepliesThere is only one placeholder control on the aspx page:
<asp:PlaceHolder ID="Placeholder1" runat="server" />
On the code behind, I am setting a variable called test and on Page_Load, changing the variable to something else. How come, when I click the dynamically added LinkButton, the test variable is not maintaining it's state:

Dim index as integer=Integer.Parse(e.CommandArgument)
Dim row as GridVIewRow=dgvAllocation.rows(index)
dim chk as checkbox
chk=new checkbox
chk=ctype(row.FindControl("chkSwapSelect"),checkbox) // chk returns nothing

The following works just fine in Chrome.
<asp:LinkButton runat="server" ID="lbEdit" OnClick="lbEdit_Click">
<button type="button" class="edit">
Edit
</button>
</asp:LinkButton>
And here is the CSS for button and its subclass.
[code]...
As you can see, nothing special; just colors and beautiful things.
I click on the blue Edit button and it fires the OnClick postback just fine.... in Chrome! But if I do the same in IE8, it just does nothing; doesn't even detect a click.
I removed the tag and kept just the word "Edit", and it works just fine in IE8 as a simple underlined link; the postback fires.
So, Why can't IE8 accept anything within LinkButton?
I am using Entity Framework with partial classes added on so I can use DataAnnotation attributes. Does anyone know how to add a data annotatin which will verify that a field is a whole number (or a DataType of int or long)? I'm surprised there is no [DataType(DataType.Integer)] attribute. I tried to create a custom attribute, but it doesn't work because the value it receives is always null:

Obviously I'm missing the point, but I don't know enough to know what I'm missing.

so I have code like above, I need to assure a record was actually returned before trying to use it... I assumed I could test for null, but that doesn't appear to work.
I tried: if (task != null) {yada yada yada}
but if I put an ID that doesn't exist in my querystring it throws an exception 'sequence contains no elements'. I realize I can catch the exception but I want to understand how I should be checking for a returned record. The .Single method intellisense says it returns exactly one record or throws an exception if more than one is found... is it also throwing the exception when zero are found I'm not sure if the issue is my check for null or that line that calls .single itself? Now I'm guessing I'm supposed to just catch the exception on the line that's calling .Single... yes?

I posted this previously but it ended up in Languages/C# rather than here. I'm not sure if I chose the wrong forum or the admin moved it. I wanted it in here so I'm re-posting it:
I have an APK file (android application archive, same as JAR file format) that I need to determine whether or not is signed, and if so, extract the certificate info.
The JDK provides a command line tool to do this:
jarsigner -verbose -certs -verify file.apk
I'm trying to determine if there's a way using the Security classes to accomplish the same thing in C# code.
Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.
I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?
How do I check if a value in the dropdownlist is in the table bound to the girdview?
Some fields bound to the gridview contain values that are not in the dropdownlist. I would like to check in the code behind whether the value is there and if not set the ddl selected value to "Select" with a value of "". If the value is there then set the selectedvalue to the value in the gridvidew.
Also, the ddl is nested inside an edit template.
Here's an example:
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Logs_ID"[code]....
