View 1 RepliesI have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).

I would appreciate any suggestions.

I have dropdownlist of dates and depending on the date that the user selects from list, I would like to filter records that fall between the startyear and finishyear columns in the datasource. (My the problem is that I do not know how to declare the Startyear and Endyear from the query in the code as they appear underlined - probably the BETWEEN syntax is wrong too).

I have a table called 'Customer' that contains customer information. One of the fields is named "CustomerType". Each record in the 'Customer' table will contain the value of either "C", "I", or "O".
I have a form that contains a "check box list" named "Type". There are 3 values in the "check box list". The values are "C", "I", and "O". The user can select one or more of these values. I have a button on the form named "btnRunQuery.
When the user clicks on the button "btnRunQuery" I want to exectute a query that selects the records contained in the "Customer" table where the value in the field "CustomerType" equal the values the user selected in the "check box list". Example: If the user selected "C" and "O", then I want the select query to select all records that contain either "C" or "O" in the field "CustomerType".
I assume that what I need to do is to capture the values that the user selected in the "check box list" and put them in a variable. Then I need to format the "Where" statement in the query and add a "Parameters.AddWithValue" command.
