View 2 RepliesI need to allow labels in disabled panels to retain a their prominent forecolor. So, I am considering replacing all labels in panels that become disabled with LinkLabels. By disabling the control and setting its disabled color to black it holds the color. However, I have always been of the opinion that one should use the lightest control possible.
View 3 RepliesI'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

I have a CSS class called selected which highlights the DIV as the current step. When they're all in separate pages, I just had to move the selected word to the next DIV.But how can I achieve the same in Master Page VB .Net? It seems to be one page for all. When the next page loads, how do I get it to highlight the next step?

View 4 RepliesI'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()
End Sub

Is there a way to do it in 2010 .Net? It errors on Forms. also it doesn't like FontSize, I don't see a setting for font size in the drop down, can we set it no more in 2010? I am using RTB's as well.

View 3 RepliesI have a label's value that is posted back from a previous page and I want to use this label to do a simple calculation in the current page, but when I do the calculation the page (refreshed) the value of this label and automatically deleted the value (Since there would be no value in postback when it refreshed).
Here is the code behind file:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Label2.Text = Request.Form("Hidden1")
End Sub
and here where I want to use the label
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Stotal As String
Stotal = Val(Label2.Text) * 10
Label3.Text = Stotal
End Sub
How can I save the value in the page via view state or any other method?

View 2 RepliesI have an Obout grid that I have been trying to work with and I put all of their code in my site so that I could have my grid stay expanded when the page does an automatic refresh.How or what is the correct way to code for a If (Page.IsPostBack) code.Next is there an online free convertor, translator, for javascript to VB.NET; if not is there someplace that I can go to where they will explain the different meaning of the javascript in comparision to what it would mean in VB.Net (such as var I think means dim or it could mean something else I am not sure.)Final is there a good source on grids and how they work with a view state or a session? But it needs to be basic as I am still trying to understand all three of those processes.

I have more than 30,000 rows in a table. It takes a lot of time to load all the data in the gridview. So I want to display 100 rows at a time. When I click next page button, another 100 rows should be displayed. When I click previous page button, previous 100 rows should be displayed. If I type page 5 in a text box, then I want to jump over to the 5th lot of rows.
I also want to display how many pages there will be. Can we implement this concept in vb.net [winform] gridview. I am using database PostgreSQL.

View 4 RepliesI have a grid view with a nested text box in it. I would like to turn view state off but the fact of the matter is when data is posted, the text boxes inside the gridview aren't available (there are no rows in the gridview on postback)I am using ASP.NET 2.0 so would this fall into control state, not view state?
Sample ASPX code of the gridview:
[Code]...
Control's information is not stored in the View State (for things like selected value and .text etc.)Control state, introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state. A page developer can disable view state for the page or for an individual control for performance. However, control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.[URL]..

View 6 RepliesI am writing a program in which I need a particular set of buttons and labels to perform the same function... in a manner such that only the button next in order can be clicked (following which an input box pops up to offer options) I tried to define a new button and a new label object which is assigned the current label/ button.
B = Button1
L = Label1
but it doesn't work. I'm not sure if this assignment is allowing only the reference to be passed as I require (so that Button1 reflects changes when I write code for B, etc.) Also i learned that arrays of objects are no longer supported in Visual Studio 2010. Is there an alternative way to do it?.... If I could define an array of objects or something similar I think I'll be able to manage..
