DataGridView Search / Sort - Comparing String In Textbox
Nov 17, 2009
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.
Private Sub txtsearch_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtsearch.TextChanged Dim sqlsearch As String Dim com As New SqlCeCommand sqlsearch = "select * from tbl_philhealth where tmc like '" & txtsearch.Text & "%';" [Code] ..... In datagridview if I search in the textbox I want to see the thing that I put in the textbox..
if i want to search for any thing in the database for example i write in the textbox the key ward how i want to search it then the result show in the table 'DataGridView'
I want to get an input from the textbox, and display the records into the datagridview, But is it possible If no records, the datagridview shows only empty cells?
This is the code to display records. con1.Open() sqlsearch = "SELECT * FROM setting WHERE mname LIKE'%" & TextBox1.Text & "%'" Dim adapter As New OleDbDataAdapter(sqlsearch, con1) Dim dt As New DataTable("setting") adapter.Fill(dt) Form2.DataGridView1.DataSource = dt con1.Close() RefreshDGV()
I am using vb2008 and MsAccess2007. Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged Dim SearchJob As String = TextBox1.Text ds.Tables("MyTable").DefaultView.RowFilter = "ProductID =" & SearchJob End Sub
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?
can some one help me show the code how to pass textbox value and then search it at datagridview.when i write "abc" in text box then datagridview wil show only a record that contain "abc" word.and can it be outomatically show at datagridview.i mean when i just type a at the text box then datagridview will show a record that contain a, and when i add b in text box = ab then datagrid will show record that contain ab word..
I want to search for a string entered in a column of a datagridview in a text file.If this string exists in the file then allow the user to enter it otherwise dont allow the user to enter the string.Also,since I am reading data from the database into the datagridview, I have not added columns to the datagridview using edit columns option. How do I do this in vb.net.I tried doing something like this:
I'm creating a new (or more) tab(s) with a multi-line textbox (filled) at runtime and some text is added. Each time I change/select a (new) tab it needs to search for a string and if found...blablabla.How do I get the control to search in?
I try to read the ID3 Info from a .mp3 file by reading bytes, and then i convert it to a string, and try to compare it to a string (that contains the same word(s)) but wasnt a byte stream beforehand anyhow ALL of my converted strings have a length of 31, regardless of if its a string that says "John" or a string that says "Teenage Mutant Ninja Turtles" how can i make my converted string have the correct length? John = 4 NOT 31!!??
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 am usingh VB.net, I have two textboxes see below:
<tr id="trCheckedBy2" runat="server"> <td> Application Checked by 1:
[Code].....
Now I want to give error message "Username can not be same" when CheckedBy2TextBox text is same as CheckedBy1TextBox. It would be good if we can use .net validator.
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
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:
Imports DiscoveryByte.AddTools.Misc_Tools Public Class ViewDiscoveryFlashCards Private DBBindingSource As New BindingSource
I have a datagridview with 2 columns, 1 is Batch_Number and another is Existing_Stock, there is about 6000 rows.My question is, I want to be able to write in a TextBox and hit a Search Button to search the Batch_Number column and filter out or highlight the row with the matching number to see the Existing_Stock
I 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.
I'm using vb,net 2.0 . How can search for the string "</script>" from asp:textbox and return alert message using javascript? I can search for "<script>" but i dont know how to get it done for "</script>".
i am trying to compare user input number to with strings. i want the users to only input numeric values in a text box. but if they input a string i want an error message to go inform then to input numbers. this is the code i have:[code]
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...
My code is:
Dim prmtimefrom As New SqlParameter("@booking_time", SqlDbType.DateTime) prmtimefrom.Value = TextBox3.Text Dim prmtimeto As New SqlParameter("@booking_tim", SqlDbType.DateTime)
