Link Button EventArgs

Hi,

It might be me but I am unable to find the EventArgs for a LinkButton or a Hyperlink. i.e. Say I have this function

protected void Clicked_Button(object sender, EventArgs e)
{
Response.Write(e.ID.ToString())
}

The above is not possible cause the e does not contian this information and

protected void Clicked_Button(object sender, LinkButtonEventArgs e)
{
Response.Write(e.ID.ToString())
}

LinkButtonEventArgs does not work cause it does not exist, i.e. so what I need is this. I have that function above which is called by dynamic links. I need to be able to read information about which link was pressed via the EventArgs, but I do not know how to do this with the LinkButton or the ASP HyperLink

Thanks In advance

TO EXPLAIN MY SELF MORE CLEARLY

Or to put it another way, how do I use this method of coding??

CurrentLink.Click += new EventHandler(CurrentLink_Click);

you see now writing this automatically produces this event

void CurrentLink_Click(Object sender, EventArgs e)
{
throw new Exception("The method or operation is not implemented.");

}

But I need to be able to write the event handler so I can use a custom function which I can pass variables into. The below example does not work

CurrentLink.Click += new EventHandler(CurrentLink_Click(CurrentLink));

void CurrentLink_Click(LinkButton e)
{

Response.Write(e.ID.ToString());
}

THank you

u can always call the custom function within the event handler

void CurrentLink_Click(Object sender, EventArgs e)
{
MyCurrentLink_Click(CurrentLink));
}

using this though

void CurrentLink_Click(Object sender, EventArgs e)
{
MyCurrentLink_Click(CurrentLink));
}

where is it getting the information for "CurrentLink" from?

REA_ANDREW

ASKER

void CurrentLink_Click(object sender, EventArgs e)
{
Handle_Click(CurrentLink);//..........<-----CurrentLink is unreachable from here
}
protected void Handle_Click(LinkButton e)
{

}

So I cannot use that function as the LinkButton CurrentLink is unreachable and therefore I am unable to pass it as an argument into HandleCLick().

Thanks for the help so far.

try ..
Handle_Click(Object)

REA_ANDREW

ASKER

Handle_Click(Object) <--------

would this not mean I would be passing an Object as the arument then and not a LinkButton?

i.e. the same would be true if I where to use sender, as this is the instance of the Object Object

that right?

REA_ANDREW,
This is not fair .. i answered ur question and was just not fast enough to comment on ur last question
>>would this not mean I would be passing an Object as the arument then and not a LinkButton?

I would have still understood a spilt between my comments and the last comment by EtherZa. EtherZa just elaborated on what i had already said ..

Didn't want to create any ill feelings :(

Saw the post late; knew the answer and skimmed through the responses to see that it hadn't been answered. Will accept any resolution that admin gives.

EtherZa

Rejojohny

no ill feelings Etherza .. I do not think u did anything wrong by answering the question .. what I was not happy about is the way the question was closed .. infact i did notice the last questin that he had asked but by the time i had seen it u had already commented and i did not see any point in repeating the same thing or saying that you were right .. if u look at the thread u will notice that it took a couple of post to actually understand his requirements ..

My Apologies, I Will post a request to the admins to split these points, ALTHOUGH.

I will assign 150 to you and 350 to EtherZa , reason being that yes you informed me to try and use Object but that was not right, and also at no point did you indicate I had to cast the Sender Argument, which would then hold the information I needed.

EtherZa, hit the nail on the head, and solved it. I indicated that this was 500pts because it was urgent. EtherZa supplied me with a working answer you did not on this occasion.

I agree that I awarded the points hastily, so no hard feelings lad! :-)

Andrew

P.S. Which section do I go to, to get this turned around?

Rejojohny

no problem .. i was a bit hasty in answering too .. what i meant was
Handle_Click(Sender) and not Handle_Click(Object) .. have been working too long on vb where the variable names comes on the right :-) .. anyway and no hard feeling ..
