Hello all,

I am having trouble pasing a querystring value as a property to one of my 
controls. My control is set to take a value on the property ProductID. I 
want the page that is calling the control to provide the ProductID value, 
that will be a dynamic field, either from a database or from the URL 
Querystring. For example, I would need to read the following: 
http://mysite.com?id=123456

123456 is what I would like to be in the ProductID value.

I tried the different codes below and none seem to pass the value:
------------------------------------------------------------------------
<uc1:control id="mycontrol" ProductID='<%Request.QueryString("id");%>' 
runat="server">
</uc1:control>

<uc1:control id="mycontrol" ProductID='<%Request.QueryString["id"];%>' 
runat="server">
</uc1:control>

<uc1:control id="mycontrol" ProductID='<%# Request.QueryString["id"]%>' 
runat="server">
</uc1:control>

and I also tried puting it in a variable and then adding it:
<%string strID = Request.QueryString["id"]%>
<uc1:control id="mycontrol" ProductID='<%Response.Write(strID);%>' 
runat="server">
</uc1:control>


I would also appreciate it if someone can show me how to easily put a data 
field value into a variable. In classic asp it was fairly easy. I tried a 
few different ways in ASP.net and I cannot get it right.

I would like the euivalent to the following classic code:
Dim strField
strField = rs.Fields.Item("field").Value


Thanks!

Elmer try this in page load even of the user control.



PRODUCTID = Request.QueryString("ID").ToString

Hope it helps..

Elmer,

	If you are using C#, the correct syntax is:

	Request.QueryString.Get("id");

	If you are using Request.QueryString[ -- then it expects an
index here indicating the nth element in the querystring. I'd assume
that VB.NET has a similar syntax.

Good luck,
Minh.

Here's yet another way to accomplish this with VB.NET:

Dim requestColl As NameValueCollection
requestColl = Request.QueryString
Dim requestArray() As String = requestColl.AllKeys
ID = CInt(requestColl("eid"))

When using this approach, however, you must include the following line 
outside of your class definition:

Imports System.Collections.Specialized

Elmer, I have tried it out, and although I got my solution to work, but I 
am not sure whether it is what you want to accomplish.
Follow the steps below and see whether you can understand how it works 
after that:

Create a VB Web Application.
Add a Web User Control in the same project.
In WebUserControl1, add a TextBox.
Double-click on any part of the form, and above the Page_Load event, type 
this: 
    Public EmployeeName As String

and inside the Page_Load event, type this: 
        TextBox1.Text = EmployeeName

Now go back to Design View of WebForm1, and drag WebUserControl1 from 
Solution Explorer onto WebForm1.
Double-click on any part of the form, and above the Page_Load event, type 
this if it is not there yet: 
    Protected WithEvents WebUserControl11 As WebUserControl1

and inside the Page_Load event, type this: 
        WebUserControl11.EmployeeName = "Elmer M."

If you manage to see your name in the TextBox, then it is working normally.
You can of course change the string "Elmer M." to Request.QueryString
("id") or rs.Fields.Item("field").Value.

For more info, 
look for 'passing values in Web Forms pages' in vs.net documentation.
