Forms :: Calculate Values In Column And Display In DataGridView?
Aug 29, 2011
i am doing a small project for my business and i got stuck with this 2 weeks ago and still no progress.
I have an access db table "store" that has columns: (filldate,brand,model,plateno,mileage,litres) where i am storing these info each time a car in my company fills gas. For example (8/25/2011,Renault,Megane,5487844,3943,20).
What i want to do now is to display in a datagrid the total consumption of gas (litres) with the kilometers driven (mileage) between 2 dates.

I have a datagridview in a form in windows application in which I have a column which accepts date values. In this column I want user to enter numeric values alone and when the user moves to next cell the value should get formatted to date type value(ex: 05/09/09). Similarly I have another column which must accept alphabets alone.

I have a DataGridView bound to a binding source. I have also, however, added an unbound column in which I plan on putting numbers calculated from the bound columns. The problem is, Any time I edit my unbound column (on any row), the value doesn't stay. If I programmatically edit the values, they never show up. If I type in the cell, then upon hitting enter or clicking outside of the cell, whatever I typed disappears.

I am making a combobox from my data source. Basically, This is a projects form and the user needs to select the the primary contact which is contrained by the customer id (GETbyCustomerID) set in another field. I have it working... mostly except the combobox only displays the contact ID which is completely useless to the user. I need to know how to display the First and Last name (both are seperate columns in the table).

I have a MainForm which contain SecondaryForm as a control of the MainForm.SecondaryForm contains DataGridView which loads data from sql server and I add a collumn named SUM that SUMs all the values of the same row. This is provided within the LOAD event of the SecondaryForm.When SecondaryForm.Load events finishes, the program goes back to MainForm right after the line "SecondaryForm.Show" and here the values of the column SUM disappear.When i write those values runtime, they never disappear.

At runtime, I have a collection of rows (Row class). Each of them consist of column values, represented by instances of a ColumnValue class. The name of the columns are determined at runtime, and are in a separate columns descriptor collection (Column class).I want to create a DataGridView that displays all Row instances. Of course, the DataGridView's columns shall be exactly those specified by the Column instances in the containing collection.But since DataGridView's columns can fetch their values from a list item's public properties only, and I cannot easily define such a property at runtime, I cannot use DataGridView to display the tabular data.
' Classes for table structure representation
Public Class TColumn ' describes my columns
Public Name As String

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?

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'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:
