I am using ASP.NET. I am not sure what you will call this but I would like text to be displayed in my text box called txtName. So when the form load the text box will have faded text that will say "Required". Then when the user click inside the text box i want the user to place a value inside the text box. Is this possible in ASP.NET? If so, how can this be done????

I have a drop down menu, and based on which item is selected, I call a web service and then dynamically create some text boxes.The first time I drop down the menu and select an item, it works perfectly, and the text boxes are created and populated dynamically. However, the next time I drop down the menu (after the first postback), and select something different..fter the second postback, the original values remain in the textboxes.

View 9 Repliesurl...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.
I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

I have a textbox on a form which I load the contents of a text file into. The values for some of the properties are as follows:
Readonly = false
Wordwrap = false
Multiline = true
Scrollbars = Vertical
When the scrollbars is set to vertical, then I am able to make any changes to the text inside of the textbox, deleting, typing in new text, cutting and pasting, etc. However if the scrollbars is set to both, then the only thing I am able to do is delete the text. It does not allow me to type any text into the textbox. All the other settings are the same as before. How would I make the text region editable with scrollbars set to both?
So I am trying to change the directory where the files are beeing saved. I've made a file where the location is saved. But for some reason, when I have saved the new location and restart the application, the file is is cleared, leaving it empty.

Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.
