View 3 RepliesForms :: Label TextAlign?
Mar 9, 2009I have a simple but tricky problem: I have a label inside a container control (form, panel, or whatever). The labels anchor is set to bottom & right, auto-size is set to true and the textalign property is set to middle right. The length of the text changes during runtime. I want to ensure, that the right edge of the label stays sticked to the right edge of its container no matter what the length of the lebels text is. I know I could do that in code, but is there a simple way to do it at the design-time?

Mar 9, 2012I want to assign a string value to a variable in the DataGridView LostFocus event. I found that I can't just do variable = "string value, it will give me the "Unable to cast object of type 'system.eventargs' to type 'system.windows.forms.datagridviewcelleventargs'" error.
The function created by double-clicking on the datagridview is:

RichTextBox Lostfocus Isn't Triggering
Dec 12, 2009I have two richtextboxes, richtextbox1 and richtextbox2 on top of richtextbox1 with richtextbox2.visible = false on form load. Whatever is input in richtextbox1 is placed in an array when rictextbox1 loses focus. Now I have a checkbox that when enabled, hides richtextbox1 and shows richtextbox2. On the first time richtextbox2 is shown, i want it to display the contents of richtextbox1. This is achieved by setting a boolean flag (firsttime=true) on form load, then in the checkbox code if firsttime = true, it displays content of richtextbox1 and sets firsttime to false.

Textbox.lostfocus Vb 2008 Exp?
Apr 1, 2010Have a project which, in one place, has a form with a number of textboxes on it to receive user input. My intention is that, when user tabs out of one box into the next in the sequence, a checking subroutine is called via the textbox.lostfocus event. When I run the app, which this procedure is called by tabbing out of, say, txtTitle without entering any data, I get the Msgbox message, but it refers to the next textbox (txtFName).
It would appear that the focus moves into the next textbox before the lostfocus event is dealt with. Consequently, when the Msgbox opens, it takes the focus away from the next textbox and fires its lostfocus even, which is processed. OK-ing the warning here causes the initial lostfocus event to be processed and the Msgbox shows again. Exiting the sub for the second time leaves the focus in the second textbox. If I then use the mouse to move the focus back to the first box, I fire yet another lostfocus event for the second textbox, etc, etc
How can I trap the lostfocus event and deal with it BEFORE the focus moves into a subsequent control?
The relevant piece of code is:

Why Isn't The LostFocus Event Occurring

View 2 RepliesBreak Textbox Lostfocus Event?
Aug 20, 2010the scenario is the following: I have a textbox ,next to it a button. The user types a value in the textbox, he presses tab, I search this value in the database in the LostFocus event, if there is no match, a browse form shows and the user can select the desired value. After closing the browse form, the focus goes to the next textbox control (and exactly this I want to prevent). The user can click the button next to textbox to choose a value (the browser form appears), but in this case, after closing the form, the focus remains on the textbox control, because before clicking the button, the focus was on it.
So, my question: how can I disable the LostFocus event? Ok, I figured it out: I must use the validating event. It works. But in this case, if I close the form, the event fires up. How can I disable this?

View 9 RepliesRichtextbox LostFocus Sync With An Array?
Jan 10, 2010I have some richtextboxes which display contents of a jagged array. When the RTB loses focus, contents of the RTB are placed in the array (so new entries in rtb are updated in the array). This works OK with moderate numbers (for example jagged array of type (200)(){}) but in a situation where the array is (1500)(){} the rtb takes approx 3-4 seconds to reload when it loses focus. I was thinking of eliminating some lostfocus of triggering with this logic
On RTB LostFocus
If 'nothing was changed in the RTB' Then
Return
[code]....
Nothing was changed in the RTB means that the user Focused in the RTB, scrolled around, but did not change the content in any way. How would I achieve that codewise? In addition, is there a better way to keep the RTB updated with it's corresponding jagged array from LostFocus?

View 12 Replies.net - Decimal.TryParse Is Failing On TextBox.Leave And TextBox.LostFocus?
Dec 22, 2010I have a TextBox in a Windows Forms application in VB 2008 (.NET 3.5) where a user can key an estimate amount. I am allowing them to key dollars and cents, and I want to round to the nearest dollar. The original code had the rounding down when the data was written back to a table, and that worked fine - I have this code in a "Save" routine that fires when the user moves to a different screen or record:
Dim est As Decimal : Decimal.TryParse(txtEstimateAmount.Text.Trim, est)
Dim estimatedAmount As Integer = Math.Round(est)
I decided that it might be nice to actually do the rounding as soon as they leave the field instead, so they're not surprised when they reload the screen and find that 1822.60 is now 1823. So I took the exact same code and added it to the TextBox.Leave event handler. And the weirdest thing happened: instead of the variable est being populated with 1822.60 after the parse, it gets set to -1! What the...?
Debugging the handler shows that the value goes into the parser correctly, and if I do the parsing manually via the Immediate window, it parses correctly, but when I let the code do it, it invariably gets set to -1. What's even weirder is that any number gets parsed as -1, not just decimals, and any non-number gets parsed as 0 (which is correct).
Has anybody else ever run into this before? I tried moving the code to the TextBox.LostFocus event instead, but with the same results. I have no idea what in the heck is going on, and obviously there are workarounds galore for this, but it just makes no sense whatsoever.
EDIT: Here's the full event handler (current behavior for which is to put -1 in the TextBox):
Private Sub txtEstimateAmount_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtEstimateAmount.Leave
' Take any dollars-and-cents amount and round to the nearest dollar
Dim est As Decimal
