wierd vb.net issue - Tilted Forum Project Discussion Community

NeoSparky · 05-06-2004, 01:14 AM

Ok,
So i'm writing this app for school. Everything works great except one thing.

On one page I have 7 texbox's in a 7x2 table. labels down the left, textbox's down the right.

What happens is on load the colors for the background of the textboxs's look proper. but after the page is finished loading the background color's go to a yellowish color. (the same as the text forecolor)

If I delete every other label, it shows up properly. I also took the html output and saved it as an html file. Same issue. Removed the form tag and it renders properly, with all 7 labels.

to add to this. the browser I'm using is i.e. 6.0 on windows XP. (Same computer as the development box)

If I goto another machine running i.e.6.0 on win2k, it renders properly in all situations.

any idea's?

I do know that the swith from desgin mode to html mode can mess up your html code ... (the editor adds stuff by itself sometimes)

are u sure you don't have any css linked to the page etc ? maybe show us some code ?

sorry I thought you were talking about asp.net ... ignore my previous comment :-)

First the simple...
you have properly set bgcolor and your text color correct?
It might also help to set the colors in Code rather then the net toolbox. worth a try?

are the lbls and txtBoxes in the same Table? and when you take the lbls off it works fine?

have you tried to place them into diffrent tables?

NeoSparky · 05-06-2004, 10:57 AM

Yes, the labels and the textboxs are in the same table.
The bgcolor is set properly, tried both in code and setting it directly in the properties.

Just tried another thing.. If all the labels have the same text in them.. i..e. label#.text = "label" then they also display properly..

Here is the aspx:
<%@ Register TagPrefix="uc1" TagName="Header" Src="Header.ascx" %>
<%@ Register TagPrefix="uc1" TagName="Menu" Src="Menu.ascx" %>
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="Customers.aspx.vb" Inherits="BlueSky.Customers" EnableSessionState="True"%>

Just tried putting the labels in one table, and the textbox's in
another,, and it's workin.. still it looked better (other than the color) with labels on the left, and text box's on the right in one table.. guess i'll just have to play with the width's n such.

edit: Spoke too soon.. Now after a couple of refreshes 4 of the 7 look proper. 3 change to a yellow background upon loading.
