Gridview: embedding a texbox and button in each row, passing info from that row to a function?

I'm making an administrative interface that lists records in a GridView.

For *each* row in the gridview, I would there to be two interface elements
in addition to some information associated with the record. Those interface
elements are a Button and a TextBox. The idea is that the administrator
using the interface will fill in an e-mail address and press the button if
they want to send that particular record to someone by e-mail. (I know how
to manage all of the e-mailing stuff.)

I know how to do a variation of this using a commandname on a simple link in
a repeater, but I have never done this with a textbox.

I've made many interfaces similar to what's described above using Classic
ASP.

How would I do this in a GridView? I imagine I'd build it using an
ItemTemplate. But I'm fuzzy on how to make the UI elements repeatable, how
to determine which row has been invoked, and how to grab the necessary
information out of the dynamically rendered/named UI elements or otherwise
pass the necessary info to the function I build to invoke the e-mailing
functionality.

Hi KF,

thanks for posting and sharing us the information.

I haven't an account on thet www.experts-exchange.com/ so that I cannot see
that implementation. Here are some of my thoughts on this for your
information:

1. Use a TemplateField as an additional column in the GridView and put
Email TextBox and Button in that Templatefield's ItemTemplate. e.g.

===============
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="btnSendEmail" runat="server"
Text="SendTo: "
CommandName="Send" CommandArgument='<%#
((GridViewRow)Container).RowIndex %>' />
<asp:TextBox ID="txtEmail"
runat="server"></asp:TextBox>

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
===============

2. We need to set CommandName and CommandArgument properties for the Button
in template. So that we can reference it in the Gridview's RowCommand event
later. Register the "RowCommand" event of GridView.

3. Here we add the code in "Rowcommand" event. We first ensure that the
CommandName is "Send", and then, get RowIndex from CommandArgument.
And Find controls from the GridViewRow and do the email sending stuff ...


=====================
protected void GridView1_RowCommand(object sender,
GridViewCommandEventArgs e)
{
if(e.CommandName=="Send")
{
int rowindex = int.Parse(e.CommandArgument.ToString());

GridViewRow row = GridView1.Rows[rowindex];

Response.Write("<br/>Row: " + rowindex);

TextBox txt = row.FindControl("txtEmail") as TextBox;

Response.Write("<br/>Will send email to " + txt.Text);


}
}
============================

Hope this also helps.
