The AutoCompleteExtender does not show below textbox but in a different position

Tha autosuggest part is working fine. The problem is that auto suggest box shows in a different place altogether and not below my textbox but vertically above the box. If I scroll up or down and then click to autocomplete, its at a different vertical position again. I am also going to have autoCompleteExtenders for other textboxes so its getting very messy.

I dont know if it makes any difference but i am using tables and and this is sitting basically inside a <td> I am also attaching a screenshot of this and some code for the autocomplete portion. Thanks!
<asp:textbox id="txtContentsCommodity" runat="server" CssClass="Textbox" maxlength="300"></asp:textbox>
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" 
ServicePath="../Services/WebService.asmx"
ServiceMethod="FindItem"
MinimumPrefixLength="1"
TargetControlID="txtContentsCommodity">
</cc1:AutoCompleteExtender>

HI There,

Try to do it without tables and see what the effect is. I'm not sure how familar with css you are. Here is some code anyway. There is also a link to an article about table less form layouts.

I'm not sure how much time you have, I think that knowing css well is important for any web developer.

Is there any way around it if I dont do css for this time. I have almost 50 forms built already and changing it at this point is not an option. So i still need to use tables and not change the html structure. Below is a typical row of my example
<TR class="rowcolor2">
																<TD>Commodity Type:</TD>
																<TD>
																	<div><asp:textbox id="txtContentsCommodity" runat="server" CssClass="Textbox" maxlength="300"></asp:textbox>
																	 <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" 
                                                                        runat="server" 
                                                                        ServicePath="../Services/WebService.asmx"
                                                                        ServiceMethod="FindName"
                                                                        MinimumPrefixLength="1"
                                                                        TargetControlID="txtContentsCommodity">
                                                                        </cc1:AutoCompleteExtender></div></TD>

Ok. Can you give me a dummy link to view? I really need to see the generated output.

hi steve - i dont have access to an outside web server right now. Instead what i did is attach a zip file which has 3 files - the aspx, the code behind and the actual source code from the .aspx page . Not sure which one you needed so included all 3. hope it makes sense and sorry for the messy html.

oK. I hacked your code a little and then tested it with the default ajax implementation of the extender.Now it does appear underneath the textbox but you may need to modify the horizontal postion of the list. It just depends on how finicky you are.

Instead of trying to get your exact code to work I just cut some of it and then pasted it into a default page.

Let me you what you think.

I tried but am getting the errors below. i used your version of @register. I think ajax extensions is creating problems.

MrAgileCommented:
what version of ms ajax are you using?
0
 
MrAgileCommented:
you may need to adjust your prefix (<cc1:) similar to what you already had.

kensummersAuthor Commented:
its 2.0 ajax extensions. I changed the prefix to cc1 but didnt make any difference at all. It only wants to work with the one i had before  - <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>.

MrAgileCommented:
ok that make sense. I'm using .net 3.5.

So use the same control that you had before. And with the exception of the two lines below (in code snippet window) copy everything into your page. Make sure that the required field validator is removed and lets give that a go.

I have attached a screen shot of how the page looks on my server.

Test it with the additional code I have given you and without the required field validator and then let me see the result.

MrAgileCommented:
When you go back to square one. did you remove the required field validator? and play around with the placement of the control  itself?





0
 
kensummersAuthor Commented:
yep there is no required validator for sure. Funny thing is no matter where i put this control , be it the first row or very last one. It always pops up in the same  - somewhere in the middle of page position. Depending on how far up/down i have scrolled it might be a bit off , but its never where its supposed to be.
0
 
MrAgileCommented:
remove all  the style sheets in the page as well.
0
 
kensummersAuthor Commented:
nah man...i took out the reference to an external style sheet i was using...still nothing.

also for last few mins i have been stripping my form bare, and guess what it works, the only problem is i deleted ALL the rows except the one the control is using. ughhh
0
 
MrAgileCommented:
ok. Try this.

1. go and get the latest version of firefox.
2. download the add on "firebug"
3. strip out everything on the page that references a stylesheet
4. apply a css class to the control  CompletionListCssClass="dropdownlst" or something to that effect
5. place an inline style (see below) in your page
6. hit f12 in ff and  then move to the css tab of the firebug add on. You should now be able to affect the position of the dropdown and see what the cause is.

I only use tables for reports. I dont use them on any pf the websites that I create cos they are too messy.

good luck with it. Let me know how you go.

did i mention i hate IE. I do have firefox on my system but just didnt think of trying it on there. As soon as i did , using the oroginal form , no stripping...worked perfectly. i didnt even have to go through ur steps, although they do make sense.

Do you think i should give up on IE or is there any hope other than changing them to css?
0
 
MrAgileCommented:
Ah. Unfortunately most people use IE. Using css for layout can be challenging at first but once you have the hang of it things get a lot easier. One thing that you will notice is that IE is different for almost everything. Javascript and css are some of the differences.

I use pure css layouts for every website I build. You still have a few quirky behaviors but they are easy to change with used in conjunction with themes & masterpages.

This website is a real gem  in relation to explaining technologies (http://www.w3schools.com/). have a poke around.

one thing we did not try is to increase the spacing between the table rows. try it.

hey Steve, sorry i was out this weekend or would have replied sooner. I did try to change the height but didn't make any difference. I am just going to stick with Firefox for now and get into css when i get the time. Thanks for ur help!
