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?
View 2 RepliesI have a basic page which has fields that I read from the database and write to it. I would like to know where I should call the insert and read commands. I know about age_load but heard about page_loadcomplete.I noted that when the user refreshes the page, for some reason the sqldatasource loads the old data(before the write) even though new data has been loaded on the form.
View 2 RepliesIs 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.

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]....

I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?
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.
View 4 RepliesIs it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

View 4 RepliesI'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.

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'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?

My dilemma: I have a POCO: "ReportSource" that is generic. I have a user control wrapping up some report building logic. My user control defines a ReportSource property but it will ultimately be the job of the page that calls the user control to assign that ReportSource property. How can I define the property in my user control without specifying a T? Btw, I tried (just for larks) to make the user control generic... That ended badly. public ReportSource<T> ReportSource {get; set;} (Note that I've tagged this as C# and VB.net... C# is my norm, but I'm having to deal w/ legacy.

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.
View 6 RepliesI 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 running a program that needs to allow the user to be able to change the size of a text box at run time. I know I need to use the MouseDown, mouseMove, and mouseUp events. I just need some help with the coding to send the information.
