DB/Reporting :: Auto-Expanding In Height Textbox?
Mar 29, 2009
Just started trying to convert all my access database into Sql Server databases and also create vb .net application for them all. First problem I encountered was there doesn't seem to be anything like a continous form(I know there is a datagridview). So i thought i would create a flowlayoutpanel. Place lots of textboxes on it and fill each of textboxes with information form my dataset. now on to the problem. one of the textboxes is the item description field. This field can have one word or many words

The First Question is not that important but you know that when you click on 'Favorites' in IE 8 a form thing comes up? Well I've been trying to do that for a long time but I can't figure out how. 2: In IE8 when you expand the window and collapse the window, the toolbars expand and collapse as well. How do I make my tool bars in my Web Browser do that. 3: I actually have a third question and that's, How do you make a horizantal scroll bar on your web browser control. (just like in Internet Explorer.)

I'm trying to get specific rows in a DataGridView to resize to the minimum height required to display my wrapped text. There's only field with multiple lines, and usually its in the vicinity of 1-2, but can get up to four. When I called[code] DataGridView1.AutoResizeRow(loadcol)[/codein a for-loop, it made every column enormous,enough to fit maybe 9 or 10. I don't want the user to have to resize columns to see pertinent data, nor to have to scroll and try to remember all the data as they edit

I have a richtextarea with a bunch of text in it. I would like to somehow make it expand to fit all the text without showing scroll bars. I would like the width to stay standard and the height to expand. Is there a good way of doing this? I planned on looping through and adding a pixel to its height every time.. and then checking if the scroll bars are visible. There is no simple way of doing this in vb.net that I can find without using windows api specific methods.

How to change the height of each row of datagridview in order for it to more taller. I use this code
Me.DataGridView1.RowTemplate.Height = 100
I want it to adjust base on the content of the text.. so that each row dont have the same height and it will base only on the size of the text or content of the current row?

been trying to find examples of how to go about auto sizing the controls i have within a grid control if the users screen is larger than the default size.Currently i am unable to resize the controls when i enlarge the form. Is there any code currently that can find all controls inside the grid and resize them on the fly when the form is resized?My current code is:
<Window x:Class="Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

I just found a way to finally do this, but it still has problems. In particular I can highlight all lines in a textbox apart from the last one and when I hightlight a line the previous remains with the same yellow colour(it should change back to white). Is there any way to fix these problems?

I have a multi line textbox (in a windows form in vb.net application) that displays values from an array. What I would like is to have the height of the textbox increase automatically so that all the rows are visible in the textbox without the need to scroll down. Also I would like to know how this will affect any controls directly below the textbox in question. ie if the textbox grows in size, will it push the items below it further down or will it overlap them?

Private Sub TextBox1_() Handles TextBox1.MouseDoubleClick
TextBox1.Height += 15
End Sub
Private Sub TextBox1_TextChanged() Handles TextBox1.MouseWheel
TextBox1.Height -= 15
This code seems to work ok for dynamically controlling a textbox height. Would like to know if there is a way to have the textbox height auto size to accommodate each entry. Autosize does not appear to be a property of textbox.

I am trying to get a line to expand whilst the user hovers over a specific Label or Button, I thought the best way to do this would be using a however so far I cannot get the process to loop until the user stops hovering over the item.
Public Class Form1
Dim Sec As Integer
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Sec = Sec + 1
[code]....
That is pretty much what I have so far, it works however I have to keep hovering and then exiting the Label for the size to increase. I have tried various loops however most of them just end up in an infinite loop.Just to clarify, I would like the X2 dimension of the Line to increase until the user stops hovering over the form.

This is, at least for me, most bizarre Visual Studio 2010 behavior ever. I'm working on MVC3 project, I copied a line of code from another project (VS2010 also, MVC1 if it matters) which looks like this: [Code] Now, if I type 1.2, it's fine, nothing happens, but if I type 1.12 it is expanded to 1.1200000000000001. Both target_height and height are integers. Why does one Visual Studio display 1.1 while other expands it to 1.1000000000000001? What is going on?

[code]i want to extend the window width everytime i expand the expander control to the right.when i run the above quoted xaml and expand the expander control after the build, everything works like expected, but as soon as i manually resize the window, the content of the expander control will expand into the existing area to the left. how can i change this behaviour, so that the window will extend its width to the right side and the content will end up in that new area?

I am developing a WinForm application using VB.NET (I am fluent in C# as well, so post in whatever language) and have run into some trouble. I have an image on my form that I would like to expand when clicked on. I have all that logic set, but I want that when it expands, the user has to click on an 'X' in the upper right corner of the PictureBox to close the expanded image. While the image is being displayed, I don't want the user to be able to interact with the rest of the UI on the form.
Basically I need something along the lines of (pardon me for switching to HTML but I know this works there) creating a div that covers the whole screen, making it opaque, putting another div on top of that, and then putting the image and the 'X' button on top of that. I have tried using opaque forms (didn't work), and panels with a transparent backcolor (didn't work either). I've resorted to taking a screenshot of the form, setting it as the image of a PictureBox, and putting the PictureBox on top of that. However, that seems like way to much overkill.
My current layout is MainForm -> Dynamically create new Form and add it to Main Form -> Add PictureBox to Dynamic Form and set its image to be a screenshot of MainForm -> Add a PictureBox on top of that PictureBox and set its image to the expanded image that I want

I do have a TreeView inside a splitterpanel-control. After executing the ExpandAll()-Method, a scrollbar appears on the panel and the first nodes are no longer visible, because the panel scrolled down to the bottom-nodes. How do scroll back to the top-nodes programmatically, because I want the user to see the first nodes on the top?

I'd like to design a Winform with expanding controls if that 's overly complicated. The idea is that I would have rows of information, each with an "Expand" button. On pressing the button, the rows underneath the selected row would move down and the controls that are associated with the selected row (some textboxes/ dropdowns etc) would appear. Vice versa when you click the "Hide" button.

Heres my problem, My app outputs info into a textbox as a log and appends the new lines to the end of the textbox, is there a way i can scroll the textbox so it displays the end of the text? I had considered writing the line at the top and appending the rest of the data to it but the line is hard to do this way (it uses info from 2 seperate subs and would need a global or a new textbox) and ideally i would like the info at the end in chronological order. the textbox is refreshed at the end of each entry.

what I need to do is automatically (through a timer or similar method) look up a newly added record, and if it exists, have a number returned and populated to a specific textbox. I have the looking up the record and getting the field I want returned working fine, but I just cannot find any way to have it populate a textbox. Another small wrench in the works is that it's a web form. I think I'd be ok with a Windows form.The reason I need this is, the user will not be sure when this record has been added and it would work fine if they wanted to click a button until it is actually added to the table, retrieved and the number needed populates the textbox. However, the folks who gave me the spec prefer the user not to have to keep clicking a button for an undetermined amount of time. So, I've been trying to use a timer. I've tried everything I could think of to get it to populate the textbox. Even javascript didn't seem to work and neither did trying to a redirect back to itself. Everything is fine except for filling in the texbox.
