View 4 RepliesHow can I get my textbox to automatically insert 'http://' before the url? It is an address bar in my web browser.
It needs to check if http:// is already there, and if it isn't, add it before the url.
I have a textbox that represents a primary key in my database. Because the values are nvarchars I can't automatically increment for a new insert. Instead I have to read a value from a drop-down, perform some magic, and create a new incremented value for the new insert.
I've written codebehind that does all this when the drop-down is selected. It works, in that it puts correct values into the textbox. However when I try to insert, I get an error that that field cannot be null.
I'm pretty sure it's because I'm doing this in the codebehind : myTextBox.text = newValue
which wipes out the binding the textbox should have : Text='<%# Bind("UniqueName")
How can I calculate the needed value for this field programmatically and set it back to the screen so the user can see it (and possibly override it) and still keep the databinding intact so I can create the new record?

I am using a combobox in VB .net to show customer's name. They also can type new names if they wish. Can I somehow save these new names in my sql database dynamically?
What I mean is if the name is new and does not exist in my database, can it be automatically saved to the database?
My combobox is bound to my name table.
I was just wondering if this is possible. I have a site that admins use to add products to our database. The database is in SQL Server 2008 and I use Visual Studio 2010 using VB.net and was hoping that upon addition of a new product, it would automatically generate a folder assigned to that product's ID.I haven't found anything online that would suggest that this is a possibility, but it would make it a lot easier for me. As of right now, I have to remember to create a folder in the X: drive for each product that has been added. We are up to 645 products now,

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?
