Resize image ? Try Image.GetThumbNail(). It will give you good results if your image having embedded thumbnail. If not use Bitmap and Graphics classes to draw an image at your size.

First you have to upload the file as it through HtmlInputFile. Then you can chose to validate its type, get its thumbnail image, resize it.
I have also shared a few tips on image validation and format conversion over here:

GetThumbnail will work perfectly with images which have thumbnails embedded. But I always prefer to use Graphics and Bitmap classes as it gives full handle to resize the image.

It provides way to iterate through the collection using a foreach.

Hi all,
Can you please let me know a data bound control in ASP that can bind to a result from a stored procedure and refreshes the result by itself?
I think i may need a code in Javascrpit for refreshing data by itself?
More detailed :
I want an asp page which displays all the orders from a sql server table.
I want to be able to refresh this page automatically whenever a new order
is inserted into the SQl server table.
Please advice
Thank you

Let me explain what i exactly need :
Is there a way to automatically refresh a control on the page without the user generating an event? For example, can I refresh a datagrid on a page every 5 seconds?
Thank you very much for your help.

Why? Some users will be happier typing.

That's how HTML upload control works. But AFAIK, if you type instead of selecting, it won't post the form. Have you checked it ?

Hi,
In datagrid go to propertybuilder. Goto Format Tag and under columns, select the email column and under email column go to items and you'll find the wraptext check box on the rightside of the pane. check that check box then the text gets wrapped.

hi all,
got a nasty one. Trying to get the selecteditem that a user clicks in an gridview, however the gridview is in an update panel. At first i thought the problem was with the session state - but what actually happens is the update panel does a postback sends everything back to the server but the server only sends back whats in the update panels.
The main problem is when a user clicks the button, this causes an asynchronous postback the event fire in a different order to normal so i detected the button that was pressed after the page load event has fired and therefore miss capturing from session.
Has anyone solved this?
Here is my code: -
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
<br />
Dim selectedItemID As Integer = CType(Session("SelectedItemID"), Integer)<br />
<br />
End Sub
Protected Sub itemsGridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles itemsGridView.RowCommand<br />
<br />
Try<br />
<br />
Dim selectedItemID As Integer = CType(Session("SelectedItemID"), Integer)<br />
'Check for custom CommandName Argument<br />
If e.CommandName = "SelectItem" Then<br />
<br />
' Convert the row index stored in the CommandArgument<br />
' property to an Integer.<br />
Dim index As Integer = Convert.ToInt32(e.CommandArgument)<br />
<br />
' Retrieve the row that contains the ImageButton clicked<br />
' by the user from the Rows collection.<br />
Dim row As GridViewRow = itemsGridView.Rows(index)<br />
<br />
' Get a handle on ImageButton clicked<br />
Dim imgbtnItem As ImageButton<br />
imgbtnItem = row.Cells(13).Controls(0)<br />
<br />
<br />
selectedItemID = row.Cells(0).Text<br />
<br />
'Session("SelectedItemID") = selectedItemID<br />
<br />
End If<br />
Catch ex As Exception<br />
MsgBox(ex.Message.ToString, MsgBoxStyle.Information, "ItemsGridView RowCommand Error!")<br />
End Try<br />
<br />
<br />
End Sub
