I have a dataGridView and a textbox on a form. I want to be able to search through the dataGridView and sort it compared to the string in the text box. Ex: I type "acv" in the text box and all strings containing "acv" are sorted to the top. I'm accomplishing this with a bunch of gymnastics involving datatable.select and some clearing and filling but it's ugly and slow.

TextBox1.Text & "%'"

By using the code above, I can search relevant ProductID details in DGV when I type the ProductID O want to locate. My question is, is it possible to perform multiple search using multiline textbox? That's all the result from the multiline textbox will be searched and showed in the DGV. If this method is possible, what code should i use? or rather, should be using any SQL Statement?

how can i compare both datagridview by using ID?

example 2: ID 4039.. the data from client different from server on Notecharter "Y..JZ".. so, that ID will put into listbox..
so, how can i compare all data in row for each column from server datagridview? If the data in row are same with server, it will be ignore..
I'm building a tool to display xml within a DataGridView and then to compare the rows of data.

I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.

I have an array of words that must be sorted alpabetically using selection sort, I must then be able to search the array with a binary search. I just can't get my head around how you would go about doing it. I know that the words must be first sorted into alphabetical order. Here is the code for selection sort with numbers:
Dim pass As Integer
Dim count As Integer
Dim minmax As Integer
Dim temp As Integer
[code]....
How would you apply that to an array of strings?
A datagridview is sorting numerical values (when clicking the datagridview column header text) in the wrong order based on the initial digit:
[Code]....
Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.
I have a few classes, one is a form, the other is the source of the datagridview. I want to be able to sort the columns of the datagridview by clicking on the header. Here are the classes that I am dealing with:

Public Class ViewDiscoveryFlashCards

View 9 RepliesI have a list of customers (over 50k) that I am trying to change the way my users search and interact. Presently, they fill in parts of a first name, last name, home phone field(s) and then click a button and it searches and presents a listview list to the user for selection of the one they are trying to find. Fairly straight forward behind the scenes with a customers object making the call to the sql server on the network and returning customer objects as indicated. I want to add a datagridview control and display all customers and then have a textbox for the user to type their selection into and have the datagridview update accordingly.
I want the filter to be dynamic as the user is typing. What I have so far is the datagrid loaded with data and the text box. I also have a stored procedure that takes a string(the text box) and returns the customers collection object as the "new" datasource. But as you are guessing, that is to many calls to the database over the network. Just not very efficient. Once I have the original collection object, how can I filter it dynamically in memory as the user inputs characters into the textbox.

That also doesn't work.And the most odd thing about all this, is that the passwordtextbox is getting is value from pass_desincriptada.
This might just be a matter of taste, but I'm wondering if there's a "recommended" way to compare a variable of type Object (which might be Nothing or have a different dynamic type than String) to a string literal in VB.NET. The following options obviously won't work:
If myObject = "Hello World" Then ... -- won't compile
If myObject Is "Hello World" Then ... -- tests for reference equality, which is just wrong
If myObject.Equals("Hello World") Then ... -- throws an exception if myObject is Nothing
If DirectCast(myObject, String) = "Hello World" Then ... -- throws an exception if myObject is not a string
Thus, the only (simple, single-expression) solution I could find is to use
If "Hello World".Equals(myObject) Then ...
which looks a bit clumsy to me. Did I miss any obvious alternative, other than doing type checks or explicit checks for Nothing?(Of course, we're talking about Option Strict On.)
Actually I have datetime value stored in the database. What I am taking from the textbox is a time value. I want to extract those results from the database which are between the given time value....To be more concise, my application is a booking system for a sports club and provides an option to view alreaady made bookings.. Here i offer two options either to view all bookings for a specific game or to filter bookings. In filter bookings one option is to filter through date and time...Date option is running okay but problem lies in time part...I provide two times but unable to view bookings between them...
