I have a user control with some textboxes and linkbuttons,
when I write some text in one of the textboxes and then hit the enter key, the page load event fires.
is it possible to cause one of the other page's events to fire?

Set defaultButton property of the form to the button that you want to use.

hi benams,

What i have understood, the solution is "javascript" check for e.keycode (or e.which) and compare it with 13 the ascii value for enter key then u can call method __doPostBack("control_name","event_to_call")this will cause the postback to the spcified event in the code behind file. Check out if this helps

regards

I tryed __doPostBack("lnb","Click") and __doPostBack("lnb","OnClick"). Both of them cause postback, but non of them fires the Click event of the wanted contorl...

hey benams,

So according to ur present senario, i guess one of the following 2 will help

1. In case the control use server side event u wanna fire is an html control with runat="server" tag, in that case u need to use javascript in the following manner

<script language=javascript type=text/javascript>
function checkKey()
        {
            var key;
            key = window.event.keyCode;
            if(key==13)
            {
                var btn = document.getElementById("Control_ID");
                if(btn!=null)
                {
                    btn.focus();
                    btn.ServerClick();
                }                
            }
        }
        </script>

2) In case the control is an asp control starting with asp: then in that case the earlier way i suggested is appropriate, further follow this link to clear ur doubts

Hope this helps, and if not feel free to query again

Till then happy coding Wink | ;)

I have a web user control with some linkbuttons. I add it dinamically to an aspnet page a few times in the pageload event.
When I click on one of the linkbutttons at first time, the onclick event doesnt fire(only pageload fires), but at the other times I do it, the link button onclick event fires.
I want the event to fire at any click, anyone has an idea how can I fix it?

Hi,
Where did you set the attribute? You should set the attribute after adding the control. The controls should be rendered first and then attributes should be set.

Hi,
what attribute do you mean? I put the onclick="lnb_Click" in the aspx page(where I declare the link button). I also tryed to put in Page_load, Page init and PreRender. Nothing of them works

saanj9-Jun-09 21:24

Earlier you have mentioned that you have added it dynamically. Have you set the attributes to that link button on page load?

LinkButton1.Attributes.Add("onClick", "alert('hello');");

the following error in stored procedure

10-Jun-09 0:11

I don't add a link button dinamically, I add a web user control dinamically.
I set it to be:
lnb.Click += new EventHandler(func); (I want it to execute a server method)
* I do it in on the Page_Load of the user control(not of the aspx page)

maybe it's neccessary to access the link button from the page thar contains my user control?

Seems like a SQL question to me.... Did you google the error message ?

Assuming the error means exactly what is says, in plain English, you can't selecet th_name into a table AND select EmpGUID into @sessionvalue at the same time. That's assuming the error message means exactly what it says.

First of all this is ASP.NET Forum, there is separate Forum for SQL . So that would the proper place for ask this questions.

Did you validate the statement?

If you can't fix it based on what we've told you, then you should talk to your teacher for help. I assume you're not working on commercial code, if you were, you'd be a thief, obviously.
