I have a datagridview control that will be used to allow the user to input records. The control uses a combobox column to select a type of service. There is a rate associated with the type of service that I then want to display in the grid. The user then enters a quantity and the last column mulitplies the rate and quantity to get a total. I have the combobox , quantity and total columns figured out but I don't know how to get the rate column to automatically be selected when the type of service is selected. Below is the code.... sets up the datagridview
Dim dv As New DataView(LookupManager.Lookups.LookupServiceType)
Dim Column1 As New DataGridViewComboBoxColumn
With Column1
I read data from a xml file and display all the contents in datagrid view. I want to extract collection of columns with same or similar contents - i.e I have three columns A,B,C and five rows in xml file. In column C, row no. 1,3,5 is filled with 'X's and row no. 2,4 is filled with 'Y's. I want to extract all columns which is related to the Columns C's content 'X'.Right now I am only able to extract one column which is related to X from Column C. How can I fix this ??
i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.
After I have retrieved my data from my access database, I would like to insert text into one of the columns in a new row. Is this possible? Here's a snipit of my code I use to retrieve the data from access:
If con.State = ConnectionState.Closed Then con.Open() sdr = cmd.ExecuteReader() rtime = Now()
[Code]....
It's the rtotal_time value that I need to insert into a new row, in and cell, the datagrid.
None of the Microsoft videos I have watched, or the other posts I have seen, have given me the pieces I need to understand this process. This is the one key piece of understanding that I need to finish about 4 different programs I have started in the last 2 years. All of them key on understanding the following processes:
I'm in the process of converting an app to vb.net 2008. I was using an msflexgrid previously. I am not using a database to fill the datagrid but as the application recieves data via a tcp connection I place the data into the datagrid's columns. The problem I am having is with column widths. I found this code by doing a search on here and added to my form.
Another noob question from me...one of these days I'll get the hang of this VB!I am importing data from an Access table that has four columns/fields. I have set up the relevant headings etc on the list view control...but I have also set up a 5th column as I want to have that representing the percentage change between columns 3 and 4 (which are numeric).
Here's my code. What I want to know, is that having confused myself with code I've written / adapted from advice given etc where do I put in a forumula to add something to a column in my list view that is a calculation based on two columns imported from the table?
I finally got this code to work after hours of toiling:

Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
I finally got this code to work: vb Dim path As String = OpenFileDialog1.FileName Dim myDataset As New DataSet() Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""") Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn) myData.Fill(myDataset) DataGridView1.DataSource = myDataset.Tables(0).DefaultView

Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could: vb For x = 1 To xldoc.rows.length - 1 DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text Next
there is another problem in my system.... after publishing my project, i find that my data in datagrid view is not updated as in the ms access database i wonder why.... here i gave my coding
Private Sub Form6_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.REKOD_PELAJARTableAdapter.Fill(Me.LcrsdDataSet4.REKOD_PELAJAR)
I'm working in VS 2008, vb.net. I have a data grid that is getting filled based on a store procedure. When I preview the datagrid, I will get 29 rows back. This includes rows that have NULL values in it. And that's what I need. But when I run the program, it will only return in the Datagrid 12 rows, the rows that don'r have any NULL values. Where or how can I change it so the DataGrid will show NULL values?

i've made a small tool that searches an access DB in back end & dumps the results in a Datagridview, now i want to export those results to excel, after googling i found a code that does it for me , it's working partially for me. It writes the Headers to a new excel file but then for some reason i getting below error (on the blue line in code):
I have an application which opens one of several excel templates, fills a datagrid view with Excel Named Range data. Once the data is modified in the application I neet to save it to an excel spreadsheet. I currently have the following working:1. This sub writes 2 columns of data (Ingredient) and (Result) from those named ranges and places them in the datagrid

This code works and the only problem is that after running the code the excel application does not close.Now I need to write the completed updates from the datagrid view and the other controls back into a workbook.Ive been searching around but have not found the proper way to do this and how to kill the oexcel application in the code above.
I have two forms and I am running a sql query to provide a set of variables in my first form that I need to pass to my second form. Here is the code that I have:[code]to form 2 which then shows the data retrieved from a sql query in the load event to a datagrid view.
I'm trying to code a button which has a SELECT statement to get information from one table but I want the information displayed in a data grid view.From the data grid view, this data will be stored in a different table within the same database.Previously i had used a list box to display the information but i could not save it in the data base.[code]Is there any way you can display this on a data grid view like i did on the listbox?Im using a datagrid view textboxcolumn column.
I am using Visual Basic 2008, and SQL Server 2005. I have a single-user client-server app (i know that sounds stupid, but its for future expandibility and also the fact that documentation was easier to find for SQL server than Access files).The app is basically a medicals records system.
In one of the tables, called 'visits', it stores the dates on which each patient visits the doctor, among other things like symptoms and diagnosis. Another table stores all the patient names and IDs along with other details, and a relation has been set up between the patient ID in the patients table and the visits table. So i dragged the visits table from within the patients table (to get only the visits for that particular patient), and dragged it onto the form to make a datagridview. However, the datagridview didn't seem to recognise MS SQL server's smalldatetime format, and tried representing it as a picture. When i changed the format of the column to text boxes, it gave me a type mismatch error (Inconvertible type mismatch between SourceColumn 'VisitDate' of DateTime and the DataColumn 'VisitDate' of Byte[].) That means, for some reason, it is trying to convert the smalldatetime data to byte before it shows it, which is leading to the error. How do i fix this?
Also, I remember seeing some option for using completely custom column types in the datagridview, but i cant seem to find it now. The options in 'Edit Columns' are very limited, but i would like to set it to a masked text box, or something with a fixed format. Can someone recommend a good column type for representing dates, and how to make the datagridview show that kinda column?
how to retrieve image from access database?.. I've just finish retrieving data to the datagrid view. I want to retrieve also the image (also stored in the database as path inside the table where the data stored) in the picturebox. When i clicked the specific data in datagrid view, it will show preferred image to picturebox.
I have a few forms that the user uses to select data records and then perform some analysis on them.So the selected records are presented in a datagrid and each in turn it reviewed and the analysis data added to the extra columns, works very.
However, if the user clicks on a column to sort the grid, the unbound fields are not sorted with it, just blanked out. I can prevent them from sorting, but it would be nice if it could sort the full grid.
I use visual basic 2010 professional edition. I am working on a project on it with access on the backhand. i want to view the data in datagrid control for the stock management. I also want to setup a query in the query builder which will search the database according to the ID but i cant get it right i dont know why. i type in the form filter this: LIKE @ID + '%'. But when i click somewhere else, an error appears which says: Data type error in expression.
I'm new to visual basic 2010 ultimate. I want to make a search button to "search" ms access 2007 database for specific data and display the results in datagridview. I also want to display the data to textboxes.
