I got a datagridview that gets filled from the database. One of the columns OSorderDate needs to be formated like this - "dd/MM/yyyy hh:mm:ss" but I don't know how to apply this to the column of a datagrid. The column type is DataGridViewTextBoxColumn.
View 1 RepliesI am in the process of building an application in Visual Studio 2008/Visual Basic that has a datagrid. One field of the datagrid needs to be formatted as currency and calculate a total for that column. I have the following that is supposed to give the total cost: [Code] I understand the first two lines, since itconnects the DB to the app. The problem I have is that the following lines and how/where I am supposed to handle them. The "DtGrdVwlAlbums.RowCount() - 1" has a line underneath it and is telling me that it is not declared. I do not know what it is supposed to be declared as, and what it connects/relates to.
View 3 RepliesI have a .aspx file with a datagrid in it[code]...
The .aspx.vb file associated with it fills it in with a datagrid object.[code]...
That all works fine. However I want to format one of the columns with a particular date format. Is there a way of doing that in the vb code? I know I can do it in the .aspx by specifing AutoGenerateColumns="False" and then explicitly defining the columns, but I want to do it in the code as it's more future proof for my application.

View 2 RepliesI am trying to change the datagrid cellstyle alignment of a column in the designer. I set it to middle right but then I run it and it still aligned to the left. I have a lot of datagrids in my application but there are few that doesn't accept any alignment settings which I don't understand at all, can't see any reason, I been looking through the options if there is anything but can't find anything. I just need one column of cells to be aligned to the right whatever I do all of the columns are aligned left and there is an option in the defaultcellstyle that is sat to middle left, but when I try to change it to Not Set it doesn't change.

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

I'm looking to get the following code converted to working VB.NET code. I need to export data from a datagrid into the CSV format that the user can save off, and the code below from David in Dakota would work great, but it's in C#. This is for a Silverlight 4 site we're working on.

I have a datagridview (windows forms) that is inside an mdiChild form. The custom format is given by a "for" instance, something like this:
For row As Integer = 0 To .Rows.Count - 1
If .Rows(row).Cells("someNumber").Value = 0 Then
.Rows(row).DefaultCellStyle.BackColor = Color.DarkSeaGreen
End If
Next
So, for every row in the grid that you find, if ther value in the "somenumber" =0 paint the whole row green. Problem is, if I put the form OUTSIDE of the MDIParent - just put frmMyform.show() in my btn that calls the form-, the grid WILL apply the format; If I call it like frmMyform.mdiparent = frmMdi, then frmMyform.show, the grid WILL NOT apply the format.
