I have a datagrid and one of the columns show the size of a file.
Ex:
87 bytes
978 kb
500 Mb
766 Gb
If i get the number of bytes, calculate the correct value (in kb, Mb or Gb) to show as you can see above and add the value on the cell, it works but when i try to sort the column it does not work. It get's the wrong order.How can i format a column on a grid view so the sorting works correctly?

I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
I have a DGV that is getting data from a sql db. The dates in this db are stored as doubles ie 40025.708681
How do I format this column as Date/Time?
I tried but this doesn't seem to work.
how to do this? DGV1.Columns("HostDate").DefaultCellStyle.Format = "d"
VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I am putting together a kind of "build your own report" page that will have up to 20 options for people to select.Each option, selected by checkbox or dropdown (probably) will add on to the SQL data source to pull only the information needed and display it in a gridview.For instance, the initial query is:
Select
C.Name,
From Clients as C
[code].....
How can I do this, preferably referring to the column using the column name of "My Position" and not a numeric...If this can NOT be done....The other option is to query everything and format it - and then hide columns in the gridview based on items that are not checked. Would this be easier? (Doesn't sound as efficient to me).

I added this template field to a gridview column and need to access the value, an email address, from the column in code behind. I initially added a DataKeyNames, but this only pulls the first record value. It does not seem to select the value for each record when running through a loop.I would like to add the email to a label so that I can perhaps use a FindControl statement, unless someone knows of an easier way. I cannot get the email hyperlink to show up in the label. Works fine without the label tag except for not being able to read the email address.
<asp:TemplateField HeaderText="Email">
