Okay... my turn...

Is there a better way of doing this?

XML

<script><!--
function ChangeRB(toPlayer)
{
	document.helpout.rbPlayer.checked = toPlayer;
	document.helpout.rbNew.checked = !toPlayer;
}
--></script>
<script for="ddlPlayer" event="onfocus"><!-- 
ChangeRB (true);
--></script>
<script for="cbExistAsGM" event="onfocus"><!--
ChangeRB (true);
--></script>
<script for="cbExistAsTO" event="onfocus"><!--
ChangeRB (true);
--></script>
<script for="tbFullName" event="onfocus"><!-- 
ChangeRB (false);
--></script>
<script for="tbNick" event="onfocus"><!--
ChangeRB (false);
--></script>
<script for="tbEmail" event="onfocus"><!--
ChangeRB (false);
--></script>
<script for="tbLocation" event="onfocus"><!--
ChangeRB (false);
--></script>
<script for="cbNewAsGM" event="onfocus"><!--
ChangeRB (false);
--></script>
<script for="cbNewAsTO" event="onfocus"><!--
ChangeRB (false);
--></script>
<script for="cbNewAsTMC" event="onfocus"><!--
ChangeRB (false);
--></script>

I don't want to use onfocus="ChangeRB();" because they're actually <asp:...> tags, which have a tendency to deal with events on the server. So what I'm looking for really is a way to say "execute this script when focus moves to any of these controls..."

This works fine as it is but it seems like a waste of bandwidth to me so any abbreviated way of doing it would be a bonus.

Why not? Thats what ASP.NET uses onclick="__DoPostBack()" in their controls...The function gets control control of what is going to be done.

Hmmm... I prefer to keep the commenting in there, just in case someone has scripting blocked or for some reason is using a browser that doesn't support it.

I had a problem doing this with a text box onchange but looking again, I might have done something stupid like using OnTextChange because I can't see why it would go wrong.

Ho hum, I'll try it that way then Big Grin | :-D

Using "onfocus=" doesn't work.

For some obscure reason that I can't see, it doesn't work at all for the drop down list. It does work for the textboxes but the checkboxes are wrapped with a SPAN tag which gets the onfocus; no use to me.

Sigh! Oh well. Back to the inefficient method unless someone has something else...

Why are you doing that?

<input onfocus="function()"

will do it, not?

NO! I'm using WebForms so the declaration is
<asp:CheckBox id="cbNewAsTMC" runat="server"></asp:CheckBox>

Just override RenderContents() and add the event to the input tag that you will have todo yourself (its only one line, just check the output in a webpage and copy/paste). The style will still be preserved.

Hope this helps Smile | :)

Oooo, now that's an idea! I haven't played with WebControls yet but that's a good plan. Cheers leppie.

Yes, its very easy Smile | :)

Just make your control in your favourite HTML editor. Copy the HTML to C# strings, make some variables and use String.Format() to assign in HTML. As easy as pie (not that I ever made one, but at least I'm eating one now Smile | :)

)!

Cheers Smile | :)

actually, CheckBox is a special case. MS made some tradeoffs with CheckBox and RadioButton which aren't readily apparent until you try to add script to them. The surrounding span tag exists so that styles applied to the checkbox will also apply to the label.

one would be better off using the HtmlInputCheckBox and HtmlInputRadioButton for these types of issues. This is because these two more closely match the API for the html elements, and thus have better javascript integration abilities.

Paging results

I have a result set in an array of objects, which I bind to the data grid. How can I page this? I tried the properties, I actually paged, except that inspite of clicking on page 1 or 2, it always shows page 1. How does page 2 get shown?

When you click on a page link, it simply throws back a PageIndexChanged event which you then need to handle. DataGrid1.CurrentPageIndex = e.NewPageIndex will change the page for you but note that you must DataBind the grid after you change the index.

Resizing TextArea

Hi all

I have a TextArea in a TABLE, but I want it t occupy the width of the table. How can this be done? COLS property is not handy at all!

CHeers Smile | :)

I think you can use width="100%" but I also have it in mind that this only works in IE5+. I may be wrong on both counts. I tend to stick to set widths wherever possible with textboxes; not pretty but it works and with all browsers.

Use COLSPAN instead.

I have tried the COLSPAN in the TD , and width in TD.

You only have one TD in a TR? Is that common all the way down?

Did I read your question right the first time around? Was you saying that the textarea must fill the TD? In which case I return to my original answer: style="width: 100%".

We were thinking you said that it must fill the width of the TABLE, so you needed to use colspan to make the TD several columns wide.

It works now, just had to add to my CSS class.

How are you using it? A TEXTAREA tag must have a /TEXTAREA closing tag, and is valid only within a form. Put a form inside a TD element, with a TEXTAREA inside the form, and apply the COLSPAN attribute to the TD.
