Displaying Selective Columns In An Asp.net Gridview?
Oct 10, 2011
This is a follow up to my previous question: Filter DirectoryInfo files by date in asp.net
I have a gridview that is populating data from DirectoryInfo. However, I only want to display certain columns, and customize the column names and the hyperlink value in the row.
My code is:
Dim files As FileInfo() = New DirectoryInfo(strDirectoryPath).GetFiles().Where(Function(x) x.LastWriteTime >= (dtStartDate) AndAlso x.LastWriteTime <= (dtEndDate)).ToArray()
[Code]....
How can I loop through the columns, to display only "name", "extension" and LastWriteTime?

I have a gallery which holds a large number of thumbnail images and I want to show 6 at a time.
I have this working using the code below, but I can not get the images to display as 2 rows of 3 - it shows as 6 rows of 1.
I can get the desired result by using a datalist but that stops the pageindex function from working.
I'm sure there's an easy solution but I can't figure it out.
<asp:GridView id="GridView1" runat="server" AutoGenerateColumns="False" AllowPaging="True" PageSize="6" onpageindexchanging="PageIndexChanged" PagerSettings-Mode="NextPrevious" PagerSettings-NextPageText="Next" PagerSettings-PreviousPageText="Previous">

In my application,i have a gridview in which columns are created at runtime.Actually these columns are created when i am entering data in a database table.[code]where Column1,Column2,column3 may vary during runtime.i need to enter values to these columns during runtime.But i cant bind these columns because these are created during runtime.The first column "Description" will not change.It will remain constant.For each description, there will be values for each column.At last these data will be saved to the database.How to add columns in the gridview during runtime?

I'm trying to write a jukebox application as part of my undergraduate coursework at university, and have hit a brick wall. Using while loops, I'm trying to display tracks/songs under particular genres, as listed in a simple text file, from which the programme reads.The issue is, although I can get the columns to be named after the appropriate genres, as stated in the text file, the songs are read, and placed in the first column, regardless. I can't seem to get them to move to the next column, when the previous genre is finished.[code]

I am making a change to some code written in vb.net, its a winforms app. The menuitem uses the System.Windows.Forms.MenuItem control. I need to display the values in that drop down menu into 2 columns. It displays a number of items and therefore is too long.I wish to display the items side but side in 2 columns. In C# you can use ToolStripMenuItem which allows you to display multiple columns. Even though ToolStripMenuItem is available in Vb.net its difficult for me in the current app to switch to that tool.

I am working on an ASP.Net website and have a GridView displaying some data,in the OnRowDataBound event I am setting the border of the row for certain rows based on some criteria. This all worked fine when I was testing my pages locally, however when I put these pages within our master page (this is part of a company intranet site) the row borders disappear in IE yet display fine in firefox.
Is there anything that could be causing this? So far there is no CSS style applied that I know of as I set the border inside the event handler like so:
e.Row.BorderStyle = BorderStyle.Solid
e.Row.BackColor = Color.FromName("#fed69c")
e.Row.BorderColor = Color.FromName("Red")

I've got a gridview with two buttons in it. I would like to determine which button has been pressed in my VB code. Is this possible? I've been able to determine which row number has been pressed, or what the value of the first element in the row is, but columns don't seem as easy.

I'm making a console game that shows some data:
#: Item Name Item Slot Cost Item Price
in that order. The thing I want to do is to make it come out in nice even columns...but I can't seem to make it do that. It comes it out in nasty uneven rows that don't look attractive...
Basically, here's what it looks like now:
1. Sword Slots: 2 Price: $40
2. W. Stick Slots: 4 Price: $1
I want to get each column to line up nicely with the other (since I control the size name).

I have two comboboxes say
DDL 1 : Artist
DDL 2: Albums
And a Gridview containing (album name, artist name, no.of tracks, year, etc), What I want to achieve is: when an option(artist1) in DDL1 is chosen, then the albums related to DDL1 needs to display in DDL2 and also it must update the appropriate values in the gridview (artistname, albums(album name -no of songs, year)etc... based on the selection made (language: Asp.net(VB)-Sql server ).

I am creating a WEB report in Visual Studio 2010 in VB.net. The report needs to display a table (please see the attached image). I am thinking to use the GridView component which i think it's the most appropriate one to choose. In the database there are students' data and marks. I can't alter the database in any way and i have to use Visual Studio 2010 with VB.
What i need to do is to show 3 different pictures(for example) depend on the student's marks. I got the pictures file in PNGs but this can be flexible.For example, over 70 will be a Smile picture. over 60 will be the Normal face. and over 40 will be the picture with no smile. I bit difficult for me to explain but i hope u get my point.
So pls advice me how can i achieve this. I am quite a newbie to this pls put as detail as you can. if there is a choice between client and server side script, i prefer server side script. Data source can be flexible (sql, or linq or anything).

I'm trying to create a document that displays a list of items, with details below each item. I feel like what I'm trying to do should be relatively simple, and the answer is hiding under my nose, but I can't find what I'm looking for.
For an example, let's say I'm just listing people, with a child list of their favorite foods.
This is how the data will eventually be displayed:

I'm trying to do this with a gridview control. I'm not sure that's what I should be using. But what I'm having trouble with, is getting the gridview to only list items with a unique USERID. And then using that unique USERID to list each item individually below.
Is there any kind of "automated" way of pulling this off using standard .net controls without going in and manually piecing it all together from the codebehind?

I have a variable defined as follows:Dim iRows As List(Of String())I've also been converting that to a list of lists just to make it easier to work with.Dim iRows As List(Of IList(Of String))I would like to bind that list to a GridView using the contents of the nested array/list to dynamically define the columns. I don't know ahead of time how many columns there will be, but I do know that they are all the same throughout the list.

I re-wrote this to make it more readable. If you want to skip right to the chase, look at the ALL CAPS comments in the code blocks. All necessary code has been included for debugging. I've searched multiple forums (including ASP.NET), and the MSDN library and cannot fix this >.<
