Calender control - how to get the day hyperlink

[yarbrough40]

Gang, using the dayrender event I'd like to cast the hyperlink that displays the day to a linkbutton or some type of aspx control to where I can apply some custom javascript to it. For the life of me I can't figure out how to do this. Cast, CType, DirectCast don't work. The control renders itself as a <a href></a> literal control . Any tips on an approach?

Can you post the code you've tried along with any error messages?

[yarbrough40]

I'm not at my machine now but a code example is something like

DIm lb as LinkButton = CType(e.cell.Controls(0),LinkButton)

the error is 'cannot cast type LiteralControl to type LinkButton...'

Anyway, as a solution, I decided to simply clear the controls in the cells, then dynamically create my own linkbuttons. I would prefer to avoid this if I could only because it creates a little more overhead on the postback.

Place a break point on that line and find out which index the LinkButton control exists?

Thanks, the control exists at index 0. the problem is that there is no way to cast the control to some type of aspx type in order to apply custom attributes to it.

Oh, I see what you are trying to do.
Hmm...you can't do that.

When it is rendered, does the day have an ID associated with it?

yes, e.day.date is there so the solution I have settled on is to just clear out the controls in each day cell then instantiate a new linkbutton using that date. It would be nice to avoid that route simply to keep the overhead down. asp.net as we know is pretty resource heavy in general. It is what it is : )

You might have to overwrite the controls...

Or you could look into a JavaScript solution that attaches a click event to the "day" since there is an HTML element with an ID for the "day". Unless you meant to say "no, there is no ID associated with the Day".

It really sounds like you are doing something more than you probably need to. What exactly are you trying to accomplish?

I want to add custom javascript to the existing day hyperlink so that onmouseover I can identify that it is truly a click on that hyperlink as opposed to a click on the larger day-cell (I am firing a different event on the cell click).

Ok, write a JavaScript function that retrieves all of the hyperlinks within your calendar.

I believe the calendar is rendered as a table right?
The table should have an ID and you can use the document.getElementByID() method to retrieve it. Once you have the table, you can use tableVariable.getElementsByTagName() to retrieve all of the hyperlinks within the table.

You can then loop through the hyperlinks and attach a click event to them so that you can set a hidden variable or something in order to indicate that it was the hyperlink clicked, as opposed to the cell.

use a JS loop... great idea!
