I have to implement a column (TransactionCompleted) which will only hold two states Yes/No. I am using SQL Express and wonder which would be the best DataType to go for that column, if I prefer to display the data in a DataGridView column as CheckBoxes later in my application?
View 5 RepliesI am using VB express 2008 with MSAccess as Database. I have a table DailyExpenses in MsAccess with four columns of which one is ColumnPaid having checkboxes. I used following query to display records of DailyExpenses in Listview: Dim cmd As New OleDb.OleDbCommand("Select * FROM DailyExpenses ", con)
It is working fine but it displays False in the column PAID in Listview instead of checkboxes. How i can display checkboxes in Listview?
I am having trouble in allowing the user to select the row in the datagridview.
I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.
Currently i have the below code which can populate the checkboxclumn only.
dbProvider = "PROVIDER=MICROSOFT.Jet.OLEDB.4.0;"
dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"
con.ConnectionString = dbProvider & dbSource

i have a problem with a SELECT statement.I have a table <EisagogiStoixeion> with 6 columns, one of then is < AgonPeriodos>. I want to display data in a datagridview depending on the column <AgonPeriodos>. I use the Select statement like this :
SELECT * from EisagogiStoixeion where AgonPeriodos = '" & textbox1.text &"'.
Value not set for one or more required parameters. This is my problem on the fill command.
If i don't use the where statement everything is ok and i can see the data including the data from the AgonPeriodos column.
I believe the following code, which clears/unchecks the checkbox in the "RowSelect" column, actually runs, but it runs VERY slowly. In testing I have approximately 2300 rows in my DataGridView:
Private Sub btnClearAll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClearAll.Click
Dim curRowIndex As Integer = 0
Try
dgvWISDataGrid.SuspendLayout()
For curRowIndex = 0 To dgvWISDataGrid.RowCount - 1
[Code] .....
The app appears to "hang" because this loop is taking so much time. When I hit the pause button, it always seems to freeze on the "dgvCell.Value = False" statement and when I hover over it the popup says "Property evaluation failed." Something is taking quite a long time or is interfering with this routine.

View 5 RepliesI am working on a project. Part of my project requires me deal with datagridview in windows form. I used 'Choose Data Source' wizard to display data from Microsoft SQL Server 2005 and into the datagridview. In my windows form, I have a datagridview with the columns - Email , CustomerNam e and Select. I also have a Add Contact button.
I have 2 questions which is:-
1) How do I insert checkboxes in the Select column
2) Upon inserting checkboxes in the Select column how do I display the rows, that I have selected using checkboxes in the Select column, to display into the textbox in another windows form?

View 5 RepliesAt runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn
MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp")
InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred.
By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:

Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?

I'm just wondering if it's possible to display a string in a integer column in a DataGridView? The reason I'm asking is that I have a column wich displays the place for each runner (it's a sports application). And if the runner is disqualified, it will display "DSQ" instead of the place.
Now, if I want to sort by clicking the column header, there's a problem if there are more than 10 runners. If there are like 12 runners, the sorting will be like this:

I need to display an two-column editable grid not bound to a database. I took a look at ListView with Mode=Details, but it appears that only cells in the first column can be edited. I then took a look at DataGridView, and am having two issues:
1. When editing a cell, it adds a new row: [url] How can I prevent this?
2. I don't like the grey background and would like the grid to fill the whole space, right and below.
BTW, if you know of a good tutorial on using the DataGridView unbound, I'm interested. [Code]
I have a SQL database, with some "status" strings. For every status I need to display a .bmp image .
I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:
Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)
I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.
I edited the DGV, and add a new image column.
I created a directory in my solution called "references" where I put all the .bmp files
I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.
LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?
I am using a list<of T> as a data source for a datagridview and would like to handle the draw event of the datagridview to evaluate the string length of the column cell. If larger than a particular number then I would just do something like

View 2 RepliesI have a data grid view that contains several columns. The first column is the only column I care about and it contains Result IDs. The view may be filter from time to time. I want to get the Result IDs from all the visible rows and put them into a table variable so I can use ADO.Net to send that table to a SQL Server stored procedure. I currently use a loop (see below).
