I want to set header column width for grid view. I tried HeaderStyle-Width="30px". But it is depending on Item columns. The column width is setting based on item value. But I want fixed width even if it has value or empty.

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.

View 1 RepliesI am trying to format a string of arbitrary length into a fixed width field for display.
Let's use a width of 20 as an example, and call the string to be formatted s. I'm adding the formatted string to a StringBuilder named b.
Dim b As New System.Text.StringBuilder()
Dim s as New String
If the string I want to display is shorter than 20 characters, I can do this:
b.Append(s.PadRight(20))
or
b.AppendFormat("{0,-20}", s)
So far, so good. But, if the string is longer than 20 characters, I want the string to be truncated to 20 characters as it is appended. The code above appends the entire string.
I tried this:
b.Append(s.Substring(0,20).PadRight(20))
But, this fires an exception if the string was shorter than 20 characters.
So, I ended up with:
b.Append(s.PadRight(20).Substring(0,20))
This seems to do the job. The PadRight prevents the exception by making sure thet string has 20 characters before the Substring is performed.
I was wondering if there is an alternate method that would look more elegant and avoid padding the string just so prevent the substring from causing an exception. Have I missed a feature of String.Format that can accomplish this in one step?
Edited to add solution:
I ended up with the following code:
Module Extensions
<Extension()> _
Function AppendFixed(ByVal b As StringBuilder, ByVal s As String, ByVal width As Integer) As StringBuilder
[Code]....
This uses an extension method to clean up the syntax, as suggested by Joel and Merlyn, and uses the StringBulider Append overloads to avoid creating new strings that will have to be garbage collected, as suggested by supercat.
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 found a code snippet online[code]...
But the problem is that the text it outputs isn't properly formatted. It must adhere to a predefined width.
I am using ms-access 2002. I have to export the data of a ms-access table in Fixed Width format. To accomplish this I am using DoCmd.TransferText method.
DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification."
Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with
DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt"
but no success.
For delimited format it is working fine
DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt"
I have gone through the link [URL]
Error message is same as of me but example shown is related to import of txt file.

View 2 RepliesI'm at the Studio 2008 stage in migrating from VB6 to Studio 2010. My application appears to run OK for the most part, but my MSFlexGrid display's single column is just 8 or 10 characters wide -- it should span the entire grid display (i.e., have the same width as the grid).The Studio 2008-Upgraded code sets several grid properties correctly, but the statement ".ColWidth(0) = .Width" (in the scope of a With block) causes an error. So does the statement ".TextMatrix(0, 0) = string".
Not only are these properties not included in the upgraded control (now identified as AxMSFlexGrid), but some column-related properties are greyed out in the properties list. My grid size was set originally by cursor drag, and the present .Size sub-properties of .Width and .Height are set to the numbers 593 and 329, respectively. (My form has a fixed size and is user-moveable but not user resizable.)

I've a data grid whose source is a data table.The columns in the data table are Serial No.,Item,Description I want the width of each column to be different, like ,the width of serial no. should be very small and that of Description to be lengthier.But, everything is of the same default width.How to adjust the width of each column in a Data Grid so that appearance could be improved?
View 3 RepliesThis problem has been perplexing me for some time now and I've tried various methods of implementing this but all have failed or have been very messy. There must be a recognised way of doing this On a form I have a treeview and listview control. The treeview allows a user to select a node and the listview shows the items within the node - pretty standard stuff. The possible columns (or subitems) list for each item in the listview is big (20 different columns in total). Some users will want to show certain information whilst others won't. Users will also want to customise column location and widths.
Implementing the customer location and widths is easy enough using standard My.Settings variables to store and retrieve the information. The problem is allowing the user to select which columns they want to be visible at any given time whilst still allowing for access to the relevant subitems.
The only method I know to achieve this currently is to set Column.Width = 0. This is not a good solution because the user simply extends the column out again from the user interface. I need to hide the column properly.I've been told that using a repository cache is the way to do this. Unfortunately the person didn't describe this properly and so I'm still stuck at sqaure one. My database access is achieved using Linq to Sql.
