ASP.Net – Add a default value to a binded dropdown list

webinfinite — Mon, 13 Jul 2009 16:07:58 +0000

Hello, today you will learn how to add a default value such as “select a value” to the top of your bound dropdown list in vb.net. I am not going to show you how to bind your dropdown list, you can do that by searching this in google if you do not know how to do this.

After your dropdown list has been bound, you should use the following code after you close your connection to the database.

Dim Item As ListItem = New ListItem
Item.Text = “select a value”
Item.Value = “0″
Item.Selected = True
BoundDropDownList.Items.Insert(0, Item)

Hope this helps.

Luckily these days there’s another viable alternative: MySQL.

How do I explode/implode a string in asp.net

webinfinite — Mon, 02 Mar 2009 23:04:39 +0000

So you want to separate your string using explode or join your string using implode in vb.net? Explode/implode are functions of the php environment and do not exist in asp.net therefore you must use the split() function to get your results for explode and join() for implode.

Split() Example

mystring = “hello;sir;how are you”;

arrayData=mystring.Split(mystring,”;”)

Result

arrayData(0) would equal “hello”

arrayData(1) would equal “sir”

arrayDate(2) would equal “how are you”

Join() Example

Dim JoinArray(3)

JoinArray(0) = "Welcome" JoinArray(1) = "to" JoinArray(2) = "Web Infinite"

Dim strSentence as String strSentence = join(JoinArray)

Result
strSentence would equal to “Welcome to Web Infinite”
