Hi,

I have a gridview control on a page that has as its column a hyperlink
field. This hyperlink field opens another page and passes a parameter.
The hyperlink field has values as follows:
DataNavigateUrlFormatString = ManageUser-MBoxes.aspx?User={0}
DataNavigateUrlsFields = UserName.
The gridview is bound to an SqlDataSource control which returns the value of
UserName.

I want to display the value of the selected UserName field passed in the
parameterwhen the linked page is open in a TextBox control.

How do I bind the value of the TextBox control the the parameter passed to
the page via the hyperlink?

Any help would be appreciated.

Hi Morris,

As for the "bind url parameter from linked page to textbox" issue, I think
you can consider the following means:

1. If using code behind is acceptable, you can simply put the following
code in Page_load event to attach the querystring parameter to the Textbox.
e.g.

===============
protected void Page_Load(object sender, EventArgs e)
{
txtUsername.Text = Request.QueryString["User"];
}
===============

2. Another approach is using databinding expression, e.g.

<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtUsername" runat="server" Text='<%#
Request.QueryString["User"] %>'></asp:TextBox>

but you need to explicitly call "DataBind" method of the textbox to trigger
the databinding:

protected void Page_Load(object sender, EventArgs e)
{
............
txtUsername.DataBind();

}



3. Another means is use the new feature of ASP.NET 2.0, you can build a
custom expression builder. This can help you embed normal codesnippet in
your ASP.NET server control's tag(attribute). Here is a good blog article
detailedly describe this:

Hi Steven,

I used option 2 and it worked well. Thanks for your help.
