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
View 9 RepliesThis 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 made an application that requires you to log-in to be able to use the search features and profile. How would I write the code to be able to log-out without closing out the application and just return to the log-in page?
View 6 RepliesI am using MS Access 2007 as database and VB 2008 to build an application to show the content of 2 tables as a single table.I have two tables in MS Access and i have linked both the tables using "ID" as primary key(1st Table),foreign key(2nd Table). I used Query Wizard to show the data of both tables in a single table(3rd Table).I am able to view the content of all 3 tables using datagridview in vb 2008(Using Code), but i am unable to add,delete,save and search the content of the table using code. My concern is,i will be able to do all these operations using codes only.Would you please help me out in this.
View 5 RepliesI want to be able to type text in a search box (textbox1) and have the datagrid adjust at the same time.

My application uses 3 DataGridViews in asingle Windows form. The 3 are never visible at the same time, and I have a sityation that I cannot figure out. The first examole below works perfectly:
For Each row As DataGridViewRow In dgvBooks.Rows
If row.Cells(4).Value.ToString = "YES" Then
row.DefaultCellStyle.ForeColor = Color.Red
[code]....
The only difference in the 2 blocks of code is the name of the DataGridView. I'm at a complete loss to figure out why one works completely and the other only partially. I have checked the execution, one step at a time and everthing happened at the right time and accurately, The upper case string is correct as is rhe index designation of the field, and I'm lost for a reason.

When I modify and delete data in a DataGridView, I get the error:

I successfully connected a remote MySQL database and it is listed in the Data Connections. My database has two tables, inventory and history, both work and I can retrieve the data from each.The problem is when I try to link the inventory table to a datagridview object. As soon as I enter the configuration wizard a red x appears in my data connections. Regardless of this, however, I can still successfully add my history table. The problem is that the inventory table name isn't visible and I get this error:<``>Could not retrieve schema information for table or view ``.The inventory table is what I need and I don't understand why it blanks out.
