AFAIK Server.Transfer tells the ASP.NET service to load and execute another aspx page, any other page type can't be executed by the service. You probably want Request.Redirect?

Image update problem

Hi,
I have an image, file upload and a button control on my webform. I am uploading a new image and attaching the image to replace my existing image in button click event. It seems to work fine on my local machine. When I deploy and run on the server side, the image upload is working fine, the image is getting replaced in the background. However my web page still shows old image. If I reload the page then it shows the updated image. I am using the same name for the image when I am doing save as in the button click event. Any inputs why this is happening?

Appreciate inputs

I belive, you are not loading the image after the image is uploaded. Could you please post your code for better assistance?

I have the Image1.ImageURL set to the same jpg filename that I am not changing. So in page load event caused by the button click event the image needs to be loaded. If it is reading from the server then it should show the new uploaded image. However it seems to be not retrieving this data from server. Please see the code below that I used. I even set the Image1.ImageURL in the page load event.. Still does not work. It works great on my local system. Please advice

<br />
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
        Image1.ImageUrl = "SiteURL here/images/studios/S-arc-0001.jpg"<br />
End Sub<br />
<br />
Protected Sub Button6_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button6.Click<br />
        Response.Cache.SetCacheability(HttpCacheability.NoCache)<br />
        If FileUpload1.HasFile Then<br />
            FileUpload1.SaveAs(MapPath("~/images/studios/S-arc-0001.jpg"))<br />
            Image1.ImageUrl = "Site URL here/images/studios/S-arc-0001.jpg"<br />
        End If<br />
End Sub<br />

You are using the Absolute URL for Image Path. Use relative path.

Say,

Image1.ImageUrl = "images/studios/S-arc-0001.jpg"

If you need the Cacheability, set it in the Page Load event.

The relative path may solve your problem.

Caching would be my guess as well, especially as your using the same file name. You could also try changing the filename to include some timestamp based hash.

Allow to Check only one checkbox at a time in the datagrid

BORN...again!4-Mar-07 15:28

Hello,

I have a databound datagrid with vehicle driver details. I add new/blank rows to this datagrid on a button click event to insert new record to the driver table and also have the edit/update functionality.

One of the columns is 'Current Driver?' which is also databound in a template column. Since there can be only one current driver for a vehicle at a given point of time, on checking the 'current driver' checkbox I need to write an itemdatabound event for the datagrid which will allow me to check only one checkbox. I do not want any messages to popup, all I want is if a person checks this checkbox for a record then it should be allowed but previously checked checkbox for any other records should be unchecked automatically so that any given point only record has the 'current driver' status checked.

Is there any way to achieve this?

I use VS2005Pro/.net2.0/VB

Thanks a ton.

Aartee.

Checkbox is meant to be multiple selections. Yet you can do it thru codings.

But radio button is the best control in this scenario.
So use radio buttons and set the groupname property as common name.

Use radio or have a JavaScript function to uncheck.

Every time you create one, write it to a database, and when you are creating a new one, check if it's existed before.

Thanks for ur reply...
i need that key to be secured. so that if u have a key then u should not be able to predict other keys. hence is there any specific algorithm for generating unrelated keys...

you can use Select newid() in SQL Server
this will give you a unique identifier. but it's longer than 12 characters.

There is no way that you can totally disable prediction of keys.

You can use the random generator in the encryption classes, that will give you an extremely good randomness.

hi,
you can use the Guid class to generate an random, unique number,
but you can't set the length or format.

the syntax is easy:
Guid number = new Guid();

i hope this helps you
