The error message says it completely.
You are trying to select the first table from a table. 
This line should be:
Label1.Text = dt.rows(0)("Column Name").ToString()

Thank you all
Finally i found the solution:
instead of writing :Label1.Text = dt(0)("Column Name")
i wrote Label1.Text = dt.rows(0)("Column Name").tostring
and it works 
Good Luck

Hello,
I have a gridview on my aspx page which is bounded to a SqlDataSource. SqlDataSource selects some rows from DB and gridview displays the results. Results are like;
Code / Point
------ / -----
FRA / 234
USA / 230
RUS / 228
GBR / 225
I want to add a new image column to gridview, and show the flags of countries on that column. I store the flag images on a folder, and flags are named like FRA.jpg, USA.jpg etc..
So i need to read the "Code" column and get the flag from folder with the text in "Code" column. As a result i will display all results from SqlDataSource plus one extra column which data of extra column will change according to the results.
Is this possible ?

Ilker.

Yes, it is.
You need to modify/construct the table with one more column for the image.
Once you have the information from the database, loop through the all the rows and for each row read the image from the folder and add the image to the datatable.
I would also think of keeping the flag images in the database and get them as a result. This would prevent me to read the images from the folder.

Thank you for your response. But instead of the ways you offered, i tried a different solution.
I added an ImageFied to my DataGridView and also i put the flags of countries in a folder under my website.
For the SqlDataSource Select Command, i added another parameter to select statement; like, "SELECT NATION_CODE, '~/images/Flags/'+ NATION_CODE +'.GIF' AS FLAG ... FROM ....... ". So the query returns the nation codes and the folder path for the images.
I select the ImageField and typed 'FLAG' for the DataImageUrlField property, so it follows the result of sql query.
By this way, i did not store the images as binary data on my tables. This was important for me, cos the data on the table was changing so frequently. Also i did not loop the gridview for the second time, so page loads quicker. My start point was finding nation code somewhere in codebehind, but the final solution seems much more better.
Anyway, thank you for your answer, that makes me think how i can use DB, so i got the solution..

hi,
I am using a griview inside an update panel.When the gridview renders it occupies the space of another division below it.It is making my layout slightly different from what i want.But when I don't use the update panel,my layout is ok.

Hi, Ive just started using vs2008
im trying to call a method in a parent aspx page from a user control.
ive usually done this using something like:
((PageClass)this.Page).Method();
But for some reason PageClass never appears in intellisense...
- I cant reference the page class from the control - this is very strange
Ive put the page and the control in the same namespace but still no luck.
Ive also tried using events instead - but after the event is assigned in the parent it still seems to be null in the control...
Any ideas what im doing wrong??
Thanks,
Chas

I am looking for a simple search form that a user enters in their search criteria then the script searches a DB for results and displays them on a new page. Any links to pages or help will be greatly appreciated.

What kind if data you want to search If the data are in DB, then just read the data in dataset and display in different page. You can use GridView, Repeater or XSL to render the result in page.
Let me know if any problem.

If you don't know how to do this, if you don't even know where to start, you should turn off the computer and read a book on ASP.NET.

Before you search further please have a look into this link[^].
I think this would give you a proper explanation on using a list view.
Keep me posted if you face any issue.

I don't think, this has any relation with ASP.NET.

I'm using a querystring to pass values from a page to page. Now the thing is if you copy the URL, close the application, open IE and paste the URL, you get the same page. So, since I believe I'm passing sensitive information I think this is very much insecure. Please help me secure my information. Say if "the crook" pastes the URL, I want my application to prompt them to login first.

You can use Session over here.
On login Page, after authentication, Store the userID in Session.
like,
Session["UserID"]=userID;
Now, validate the information in every page when you need,
Protected Void Page_Load(Object Sender, EventArgs e)
{
if(Session["UserID"] == null)
{
Response.Redirect("Login.aspx");
}
else
{
}
}

There is verious way to make it Secure. You can use encrypted Query String,
