pass parameter in hyperlink

Hi

I am displaying the results of a query in a datalist. There are 2 fields returned with one an icon set as a hyperlink as follows:

name

When someone clicks on the icon I would like the name parameter to be passed to a new page to be used in a new query. Can someone please point me in the right direction.

Matt

The simplest way of doing this is to append the name as a query string variable, e.g.

<a href="http://links.10026.com/?link=http://someurl.com?name=xyz">...</a>

Thanks for the quick response. My code looks as follows:

<ItemTemplate>

<asp:HyperLink ID="Hyperlink1" runat="server" NavigateUrl="~/Login.aspx"><asp:Image ID="Image1" runat="server" ImageUrl='<%# SetUrl(Eval("status")) %>' ImageAlign="Middle" /></asp:HyperLink><br />
<asp:Label ID="term_idLabel" runat="server" Text='<%# Eval("term_id") %>' Font-Names="Arial" Font-Size="Small" ForeColor="White"></asp:Label><br />
<br />
</ItemTemplate
Which displays my data as:

name1 name2

If the user clicks on name1's icon I'd like to pass name1 as the parameter. How do I access this term_idLabel instance?
You'll want to change the NavigateUrl property in HyperLink1 so the term_id is evaluated and passed as a parameter. Try this:

NavigateUrl='<%# Eval("term_id", "~/Login.aspx?name={0}") %>'

The string will be formatted with the value for term_id replacing the {0}.

Passing a parameter to another page

On one page I have a datagrid which is filled when the user selects some search criteria (e.g. surname or DoB) in different text fields and clicking on a button control.

The datagrid also contains a 'button column' which the user can use to edit and save changes to individual records to the db.

I use the following code to access the PK of the table in question as a parameter for my update query:

Dim strPatID As String = e.Item.Cells(0).Text
strSQL = "UPDATE blah "
strSQL = strSQL & "SET blah blah blah"
strSQL = strSQL & "WHERE patid = '" & strPatID & "'"

All of this works fine.

However, I also want users to be able to add records to a related table (which is at the many end of a relationship) based on the record they've selected from the datagrid. I've set up a 'hyperlink column' in the same datagrid which redirects them to another page where they'll be able to add data and save it. Fine so far.

The problem is of course, I need the patid as the foreign key to this second table. How can I pass this as a parameter to the second page? Am I doing this the right way or is there a better way to add records to related tables?

I hope I've made myself clear. Please let me know if you need additional information.

Thanks in advance for any help.

MoYou could pass it in the querystring to the new page:

DetailEntry.aspx?PatID=xxxxxx

On the second page, you can use Request.Querystring("PatID") to get the value
Thanks very much for the response Jim. I'll try it out.
Best regards to JimRoss:

In addition to using QueryString, you can also think of :

Session Variables as another solution, in addition to the other solutions.

Passing A Value To Server

Basic Web Form... A few text boxes and a checkbox - and a card reader...
The effect I want to accomplish is this:
The basic credit card fields are there and can be filled out. But if the
user swipes the card, I want to fill out the fields automatically and make
them read only. (So far I can do this.)
But I also want a checkbox to appear that indicates the card was swiped.
The user can clear the checkbox, re-enabling the fields so they can be
edited, but then I will no longer consider the data as being swiped. I want
the check box to disappear if they clear it.
Using server controls, if I create a checkbox, but make it not visible, then
it's not available at the client side to work with from client side code.
So I would need to send some flag back to the server to indicate a post back
and have the page re-rendered properly. But how do send info to the server
like that without having a visible control to attach the data to?
(Does this make any sense? Not sure if I'm explaining it well.)
Is there a way to send a value back to the server, in a postback, where the
data is not a property of a server control that's tracking viewstate? The
session object is only available on the server side right?
Any guidance here is appreciated. Thanks.
Jerryto send additional value to server , one commonly used method is
a HiddenControl (you will access it like Request.Forms["HiddenContrlName"]
from code behind)
or a TextBox Webcontrol with size 0 or attribute style='display:none' ..
But if the only purpose of post back is to display/check the checkbox ,
probabaly a better approach is to do the display/check in the client side
javascript ..
Instead of settign Visibility=False, you would just add an attribute to
make it hidden , but still available at client code
CheckBoxName.Attributes.Add("style='display:none'")

Okay... I can have the checkbox on the form and available with 'Display:
None'...
But I can't seem to find the proper syntax to change the display state and
make it visible on the client side...
Thanks.

there any javascript error when you call the function to display the

function toggle(id)

Once this works, you can compare with the HTML your aspx generated and that

Obviously there is some thing not right other than the syntax.. :) .. Is
there any javascript error when you call the function to display the
checkbox?...

if still no luck, you may want to create a simple HTML page with only
following code in it...

<INPUT TYPE=checkbox ID=chk1 style='display:hidden'>
<INPUT TYPE=button ID=btn1 onClick="toggle()" value="Click to Toggle
Display"
<script>
function toggle(id)
{
el = document.getElementById("chk1");
var display = el.style.display ? '' : 'none';
el.style.display = display;
}
</script
Once this works, you can compare with the HTML your aspx generated and that
may help in finding the issue..
