.NET - Textbox Control - Wait Till User Is Done Typing?
Mar 22, 2009
Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. Like measuring the time since the last textchange event and if it was > than a certain value then it would proceed to run the rest of my procedures.
Basically after I queue all works, I want to wait until all I queued has been done. How do I do so?[code]I notice there is no way to know how many threads are still running in the threadpool.
Is there a way to make the textbox stop typing when a user types numbers? I don't want an error message, I'd just like the user to be able to insert 10 numbers and then it shouldn't add any newly typed numbers.[code]....
In an application I have, when a user types in a textbox, the data in a listview is refreshed to reflect what the user is typing.As it stands, it does a refresh after each key is entered.Is there any way to smartly wait until the user has finished typing before initiating a data refresh?
Is there a way to find out if the "TextChanged" event is fired because the user is typing into a textbox or the programmer called myTextBox.Text = "something"? I don't want to react when the user is typing each letter into the textbox so I am using the "Validated" event to catch when the user is done so I can react. The problem is I don't have a way to catch when the programmer does "myTextbox.Text = "something". The only way I know to catch changes there is to use TextChanged but then I don't want to be reacting when the user is typing each letter into the textbox.
While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.

I'd like you filter some results in a grid, and i want the user to be able to type a value into a textbox, and then the grid will be filtered by that value. I don't need help with the grid or how to populate it. My question is in regards to the textbox; How can i tell when the user has stopped typing so i can automatically load the grid? I thought about doing a refresh automatically in the TextChanged event, but that seems silly since the user could still be typing more characters.
how can i format a number while typing it on a textbox. For example, I type 1234.50 on a textbox and it will show 1,234.50 on the same textbox. I am trying this with my code but with no luck.
Private Sub txtClimit_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtClimit.TextChanged Me.txtClimit.Text = FormatNumber(Me.txtClimit.Text, 2, , , TriState.True) End Sub
I want to format the contents of my textbox while typing.I know that I can do this in LostFocus event, but I want it to be done while I am typing. Does anyone have any suggestions on how to implement this?
I need to do it like this. while typing ex. 100000, the textbox would display 100,000. I tried everything I know, I fired up keypress and textchanged events but still failed.

i've got my basic AutoTyper ready (well and one with autoupdating etc in it) but it's only a singular line. [Code] What I want to do it to type multiple lines, I know I'll have to enable multiline on the TextBox. I want it to type one line per time interval using 1 timer. I don't know how but I know it would have to count the lines but from then on I'm stuck. I will need to make it type line 1, then on the next loop line 2 and go on until it's reached the amount of lines from the count then repeat from line 1. [Code]
I want that it is not possible to type anything in a textbox, but i do need to place something in it. This is my temporary
Private Sub textbox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles textbox1.TextChanged If textbox1.Text = Nothing Then Else textbox1.Text = Nothing End If End Sub
But in this way I cant place anything either. I want only that it is not possible to type something in it.
I'm using a custom webbrowser to display a special intranet for my company.I need to be able to display a custom keyboard whenever the user can type in the webbrowser. So if they click on a textbox within the page to type, this custom keyboard appears.when the user is in 'typing mode'. I thought maybe checking when the cursor changes to 'ibeam' which is the typing cursor? How might I do that, or is there an easier way?
I want it when I type anything, it will start at the third character of the textbox. Ex. I have this amount textbox that has .00 on it, whenever I type numbers it will start after the period. So if I type 300 then it will show 300.00
I want to make login form. It contain two Textboxs and one button (Login). If textbox is empty then button look like Disable If I type text in textboxs (Textbox1) and (textbox 2) both then button Enable. for logining...
I need to work with multiline textboxes. I am currently developing a web application that was started by someone else. The only problem I have is the text in my multiline textboxes is going to the next line before it needs to. I have played around with settings, removed the textboxes and added them back, and I am still having the same problem. When typing in the textboxes, the text moves to the next line after pressing the space bar.
I have a form that allows users to enter information into a few textboxes. When users click save, the information will be transferred into the datagridview.
My problem now is, for instance, there is a textbox called "Price" with the datatype "money" which users are only allowed to enter numbers. If users enter alphabets, errors will occur. I don't wanna use try catch, I would like to try different methods such stopping users from entering anything into the textbox when the datatype isn't correct - nothing will appear in the textbox when users hit all the keys in the keyboard except for numbers.
I am using third party tool "gridlookupedit" of DevXpress in my application. I have loaded the gridlookupedit control on the key Down event of it. Now if i type a character "A" the dropdown gets loaded with all values starting with "A". Now a step ahead i want to load the GridLookUpEdit only after two characters. for rg: the control must load values only when user types any two characters. If user types "A" it should not load. if user types "Ab" then the control should be loaded by the values starting with "Ab".
I have UC that inherits a textbox. It is meant to only accept numeric values. I want to be able to add a property to give the end user the choice of setting the FORETCOLOR to another color other than that which they have chosen for the normal FORETCOLOR settings. Is there some line of code that will allow me to access FONTCOLOR dialog box when a user clicks the FORECOLORNEGATIVE property setting in the Properties settings?
