I have an application that saves and loads data to and from a database, via a DataGridView.
Originally, I setup another form that accepts the data and when the "Search" button is pressed, it closes and loads it into the main form's database.
But, my boss doesn't want to do it this way. I actually like this new method better... but I can't get it to work
The DataGridView has 14 columns. The user should be able to fill out 1 or all of the cells and that data should be used to complete the search, which is then populated into the DataGridView.
I have all of that figure out, with the exception of figuring out when to call my search method.
I tried capturing the "Enter" key press in the KeyDown event, but that only works when the DataGridView itself has focus, and not when a row, column, or cell does.
I then tried the RowLeave and RowValidated events, but then I get an exception stating that I can't call that method from those events.

I'm doing a simple search of rows in a DataGridView. If the search finds a record matching the search criteria that row gets selected. I just added the BindingSource.Find method
If the row I'm searching for is currently showing in the DGV's viewable area, then my code will find the record, if it's not showing, meaning you have to scroll up or down to see the record, my search does not find the record.
(Correction: It finds the record but the DGV does not scroll to have the selected row be in the viewable area.)
Here's my
vb
Private Sub SearchForSite(ByVal site As String)
DeSelectAllDGVRows()
Me.Cursor = Cursors.WaitCursor
[Code]....

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?

Data in Table1 is as follows
Code-------product--------weight
1-------------Apple----------2.00
2-------------Mango---------3.25
3-------------Banana---------6.50
Then I have Datagridview with three columns same as
Code, Product, Weight
I have following codes
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
dt = GetTable(str)
If dt.Rows.Count > 0 Then
DataGridView1.Rows(0).Cells(1).Value = Trim(dt.Rows(0).Item(0))
DataGridView1.Rows(0).Cells(2).Value = Trim(dt.Rows(0).Item(1))
End If
End Sub
When I enter 1 in row(0).cells(0) then other two columns fill automatically, but when enter 2 in next row then nothing retreived from database.I think this line should me modified as current row and current column.
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)

This is the code I posted before. I have a thread open but it is confusing. I have a search of a datagridview. The search works. Now I would like to highlight the corresponding row of the search result. Scroll down to the highlighted row. If there are multiple results to the search critiria the next one should be highlighted.
Dim foundit As Integer = 0
Dim intResponse As DialogResult

I'm a bit of a noob at this and finding that all my research that's led me to wanting to do things right for data integrity are making it a bit more complicated on the front end.
Presently I have a Form in which I have two DataGridViews that I'm populating, each with it's respective stored procedure.
What the form is for is for linking rows from the one DataGridView (I'll call it DGV1) to a different one in the other DataGridView (DGV2).
Now to facilitate the ease of doing this for the user I want to both have the dgvs fully populated so that if the user wants they can just slide on through and manually select the rows in each they want and then there'll be a button to select which I'm planning to then use another stored procedure to then insert this connection between these two items into the database.
Another thing to facilitate this is a search bar. I want them to be able to type in something and have the datagridviews both navigate to where their selection is as well as selecting it so that it's then ready to be bound to the selection in the other.
What I'm wanting to know, and having a hard time figuring out, is how do you get such a search function to work on DataGridViews that I have bound to these read only stored procedures? How do I search and select within the DataGridView? And then how would I go about using the selection from two different datagridviews and putting those as parameters in the stored procedure that I wanted to use to then record the relationship in the database?

Am developing a software for submission as project. As a part of it, am planning to create a Phonebook package. I created a database in access and i integrated it in VB.Net.
Information:
Database name : Contacts.accdb
DataTable : Contacts
Contents in table : First Name,Last Name, Phone, Address...
Platform : VB.NET in Visual Studio 2010
I integrated the access database in VB.NET using Data->Add new Data source and I successfully made it. Now I got a DataGridView. :) Now arises a question How to search a name in "First Name" Column? I just Googled to find row Filter. That appeared gr8 to me till I got a problem of adding new records. Once I applied Filter, I couldn't see the Addition of new records and I can't make selection process in DataGridView. Then I found that Filtering is not Searching. Any one to help me in searching the data in Dataview?
I'll post my codes here:
CODE:
I have a textbox named "TextBox1", Binding navigator that is automatically generated on copying the DataGrid named "ContactsBindingNavigator" and DataGrid cotaining Contacts table named "ContactsDataGridView".

I am creating a program which searches saved .htm files for the source codes. I get the source code and do manipulation on the code to pull the values I need into a datagridview.
Is there anyway to search a datagridview column to see if a value exists first, so no duplicate rows of data will be added? I was thinking of making access table and linking the datagridview to it, but i'm not sure how to set the database links up with code (other than the gui), and then still search the column so I don't put in duplicate rows.So far, I have only come up with the way to add the data row by row...

I tried out the video tutorial from Beth Messi about how to create a search. The tutorial teaches us how to do it through query builder in which we just have to type LIKE@fieldname = '%' for each field we wish to appear on a toolstrip. A toolstrip menu will automatically be generated and placed underneath the form bar for us after we click ok.
Now, I would like to know how can I do this with code? I can use a code which will move the auto generated toolstrip into the tabcontrol but when I have more than 1 tabcontrol, that's when I start having problems - the toolstrips are starting to cover up the tabcontrol. I know I can move the datagridview lower but that is going to leave a big space above it.

I need to design a search/filter for a DataGridView. The search contains 2 comboboxes and 1 textbox. combobox1 are the field names, combobox2 is the criteria (=, <>, like), and the textbox is to input values.
For example:Users will select the Road Name field from combobox1, "=" from combobox2, and Main St will be typed in the textbox. After a button is pressed, the datagridview should filter to whatever the user inputs.

I am having difficulty with searching on a Dataridview. I want the user to be able to enter a characters into a textbox and as they enter them the Datagridview will reduce down base on the name that is being typed in.So for example the user types: Smthis will show all the Smith and all the Smarts etc.So to do this user the Textbox change event. This I think works ok. The problem I have is getting it to filter on that data.
I have a dataset:
HTML
SELECT CompanyID, CompanyName, Address1, Address2, Address3, Town, County, Country,

I have a VB.NET search routine, part of which is provided, below, that checks all Text cells in a DataGridView for a given string (inclusive), using a basic set of nested loops to perform the search:
' Search for the first occurrence of the given string
For Each row As DataGridViewRow In dgvMembers.Rows
' Skip the new row
[Code].....
is there a way to replicate this behavior using LINQ? Basically I would like the query to select (or return) the first DataGridViewCell whose text contains the search string. I've done some tinkering with sub-queries and the like, but I'm still having trouble wrapping my brain around the concepts (too many years of writing T-SQL, I guess).
