The DataTable class has a Merge method, which returns a new DataTable that you can use as your datasource:

U can show it by using SoredProcedure in DB...
or

I am trying to separate this word, as an example the String is ASP_01, so I want to separate it into two like store ASP in one variable and the 01 in another variable, is it possible for me to do this in asp.net visual basic,
I am newbie in this,
Thanks for helping me.
You need to use the Split Function. Link
dim str As String = 'ASP_01'
dim newWord As String = str.Split(new Char {"_"c})
dim 1stWord As String = newWord[0] //result is "ASP"
dim 2ndWord as String = newWord[1] //result is "01"

Error:
Conversion from string "INSERT INTO [myDB].[dbo" to type 'Double' is not valid.
I am trying to add the dropdownlist index, the dropdownlist selected item's value, the dropdownlist selected item's text and the text from a textbox.
How can I resolve the issue.
ddlInsurancePlans.SelectedIndex is a number, you're using the addition operator, therefore you're implicitly trying to convert the left (string) into a format compatible with the right (double).
Use .ToString to explicitly cast SelectedIndex as a string.

I am passing a username in a session like below and would like to get the first letter of the first name and last name. So for example Doe, John I would like to get "JD" etc. Any idea how I would do this? Thank you
Session("Username")
As an example following your requirements. Lastname stored in first position and firstname stored in last position, but the order of the returned string is First/Last
string username = "Doe, John";
string[] parts = username.Split(' ');
string result = parts[1].Substring(0,1) + parts[0].Substring(0,1);
Console.WriteLine(result);
No error checking is present for clarity, but if you want this for a real work some checks on length of parts is mandatory
If you have only spaces between the parts of the username, try with this RegEx :
initials = Regex.Replace(Session("Username")," *([^ ])[^ ]*","$1")
--> the string "[^ ]" gets every character which is not a space (you can add the char '-' if you want)
By this way, you get a solution which works with people called "John Joe Jibbs" ^^
This is just a proof of concept.

Wordpress have "p" variable in query string for showing post where id of post = p variable. Is there any way to change this var name? Or to add variable that will be doing the same thing? Im looking for a way to make wordpress recognize query like this:
wordpresssite.com/?id=123
Those are just query vars , and P?simply means post .
To change it you can create a custom post type (CODEX).
Then, for example, if your custom post type name is : "bulding" , it will show as
?bulding=xx
Just as page shows as page_id= and attachment shows as attachment= ( both are post types , but reserved and implemented as default )
That being said, I do not really understand why one would like to change it , and why is that disturbs , but I would sure like to hear that ..

If the item count for the datasource of it is less than 20,i need to generate 20 rows with single column.If it is between 21 and 40 then 20 rows and two columns.if it is between 41 to 60 then 20 rows and 3 columns and for more than 60 records then as normal that checkboxlist behave.
Any suggestion is appreciated.
Thanks

Try this:
int itemCount = <YOUR_DATASOURCE_ITEMS>.Count;
int columnCount = Math.Ceiling(itemCount/20.0)
<YOUR_CHECKBOX_LIST>.RepeatColumns = columnCount;
