VS 2008 Search Database Via DataGridView?
Mar 24, 2011
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 am making a project in VB 2008 that has a Form (form1) that allows me to add new records to a database, and another Form (form2) that allows me to search for records in a database. I have done Form1 already, but my problem arrives in Form2 where I have to query the database. This form consists of 1 textbox (txt_search.text), 1 button (btn_search) and 1 datagridview (datagridview1). The name of my database is db_extras_test2003.mdb and the table I want to search records from is tbl_contacts.
I know +/- the SQL sintax to query the database (SELECT * FROM tablename WHERE columnname = (here i dont know if i put the variable name i have set for the txtbox, or the textbox itself)).I want this in a way that I (or other users) type in the textbox, hit the Search button and the results are shown in the datagridview (i can show the results in another way if it is better to do so).I have done the connection to the database already. The code I have so far is the following, but it doesnt work

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

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)

I was wondering what was the best way to search a database. Is it possible to perform bubble sort etc or any sort of binary search to the database instead of doing a linear search. If so how would I go about doing this through an Sql statement.

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.

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?

I want to search a sql server database from VB.Net and output the results in a Listview. I don't want to use code that involes queries in it, but the queries are to be used in the data set designer, i.e the query builder.Here's what I got so far.
I created a query in the builder called SearchStudent
SELECT FirstName, Surname, Email, PredictedGrade, Notes
FROM tblStudent
WHERE (FirstName LIKE @FirstName) OR
(Surname LIKE @Surname)
Here's the code to search the database and fill the dataset

I just want to simply be able to edit a database directly using a Datagridview. That includes adding new rows, editing existing ones, and deleting rows. So far if I have been able to get one of those actions to work, the others do not. I found the codebank entry by JMC and I am trying to use it to connect to my database. I have a bindingsource, a dataset, and tableadapter created via the designer. Now I need to figure out how to combine all these components.
VB.NET
Imports System.Data.SqlClient
Public Class Form1
Private connection As New SqlConnection(My.Settings.Database1ConnectionString)
Private adapter As New SqlDataAdapter("SELECT ID, Name, Quantity, Unit FROM StockItem", connection)
Private table As New DataTable

I have searched the forums for an answer to my problem, but I have not found any solution.First of all, I know that the datagridview is "supposed" to automatically refresh when new data is entered, but in my case it does not seem to work.
I am using VS2008, with an Access 2007 database. The database has 2 tables, but I am only trying to work with 1 of those tables.For this project I have 3 forms that I am working with. The main form calls a form that has an embedded datagridview for the 1 table in it.
By double clicking on a row, this form hides (Me.Hide()), and the second form appears where the new data is entered for the row selected.
Once the data is saved from the second form, using "Update", the second form hides, bring me back to the main form once again.
If I then click on the button to call up the form with the datagridview, it appears, but not with the new data on it. If I use the "x" button (top right corner) to close this form, and then click on the button to call the form once more, it appears with the correct data.I guess my question comes down to this. Do I need to not use Me.Hide() on this form, and if so, what would I use to make sure that the next time I show the form the data has been updated?

I'm writing my first Vb application and have come to a grinding halt... I've created a windows form which has got a datagridview (which is populated by a tableadapter and a dataset generated from a SQL stored procedure) with two columns (Product and Qty), I'm populating the Product Column using a Stored Procedure, the user then adds the quantity. Once they've finished filling everything out they'll then hit a save button and I then need to insert both columns (along with a reference number which I'm getting from a text box) into a table on a sql server.
