VS 2008 Display String In A Integer Column In A DataGridView?

Nov 8, 2009

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:

C# - Display An Image In A Datagridview Column Header?

Jul 28, 2009

At 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:

[Code]...

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

Display Data From Checked Box Column Row In The Datagridview Control

Mar 14, 2011

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

DataGridView - Display Two Column Editable Grid Not Bound To A Database

Oct 7, 2011

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]

DataGridView Cell Formatting To Display Image Based On Another Column Value?

May 7, 2012

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?

VS 2008 Conversion From String To Type 'Integer'

Mar 18, 2012

So I'm trying to create a program in Visual Basic for my uni coursework and I'm kinda stumped a tad here. I've created most of it, I just need to write the files to a txt file (in the same folder as the program [bin/debug]).

I'm creating a some kind of employee reference form. Fill in your details, figures out gross pay, net pay and all the taxes an employer has to deal with. When you press Save, the details should all write to a file and I should be able to select from multiple ID's in my combobox for the employee ID reference. If I try to save a file with the same ID number I should get thrown an error. every ID should be saved under the Employee ID box.

Here's my code for the save button:

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim s As employee = New employee
