How To contain multiple fileds in the querystrig, DataNavigateUrlFormatString=xxx.asp?ID={0}&Name={1}

<asp:TemplateColumn HeaderText="稿件编号">
                        <ItemTemplate>
                            <asp:HyperLink   runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"EventPaperID") %>'
                                NavigateUrl= '<%# "CommonProcessPlatform.aspx"+ "?" + "PaperID=" + DataBinder.Eval(Container.DataItem, "EventPaperID") + "&Event=" + DataBinder.Eval(Container.DataItem, "EventEvent") %>' Target=_blank ID="Hyperlink1">
                            </asp:HyperLink>
                        </ItemTemplate>
</asp:TemplateColumn>

It is noticable that in the above code, some strange variable names are used such as EventPaperID, EventEvent, etc. Those variables are used due to the SQL query is a JOIN query between tables Event and Manuscript.

The SQL statement is as follows

     cmdManscript="SELECT Event.ID AS EventID,  Event.Event AS EventEvent, Event.OutStanding AS EventOutStanding, Event.Date AS EventDate, Event.PaperID AS EventPaperID, Manuscript.AuthorName AS ManuscriptAuthorName FROM Event,Manuscript " + strWHERE +"  And Event.PaperID = Manuscript.PaperID ORDER BY Event.Date DESC";


The following referece is good enlightening material
http://www.dotnet247.com/247reference/msgs/13/66028.aspx

am using a datagrid to display 3 bound columns and a
hyperlink column. I am trying to figure out if it
possible to have more than one querystring parameter
inserted into each hyperlink using the
DataNavigateURLField.

It looks like you are only able to specify one column
from the datasource to insert as a value that differs for
each row. The example below is one I found in the MSDN
documentation which shows one DataNavigateField and its
format string.
--------------
<Columns>
<asp:HyperLinkColumn
HeaderText="Select an Item"
DataNavigateUrlField="IntegerValue"
DataNavigateUrlFormatString="detailspage.aspx?id=
{0}"
/>
</Columns>
--------------

Conceptually what I want to be able to do is have a
format string that looks like:

DataNavigateUrlFormatString="detailspage.aspx?p0={0}&p1=
{1}"

So that I can have two query string parameters be
populated from two different columns in the datasource.
The rows would have hyperlinks that would look like:

www.somesite.com/somepage.aspx?p0=2&p1=23
www.somesite.com/somepage.aspx?p0=5&p1=19
www.somesite.com/somepage.aspx?p0=8&p1=99
.....

Is there a way to do this?

thanks
Michael

Hello Michael,

It turns out that this is pretty easy to do. Here is the code:

>>
            <asp:DataGrid id=DataGrid1 style="Z-INDEX: 101; LEFT: 8px; POSITION:
absolute; TOP: 8px" runat="server" DataSource="<%# dataSet11 %>">
                <Columns>
                    <asp:TemplateColumn HeaderText="URL">
                        <ItemTemplate>
                            <asp:HyperLink runat="server" Text='<%# DataBinder.Eval(Container,
"DataItem.title") %>'
                                NavigateUrl='<%# DataBinder.Eval(Container, "DataItem.title") + "?"
+
                                DataBinder.Eval(Container, "DataItem.title_id") + "&" +
                                DataBinder.Eval(Container, "DataItem.pub_id") %>'>
                            </asp:HyperLink>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                </Columns>
            </asp:DataGrid>
<<

What I did was create a project with a DataGrid populated from the pubs
database / titles table. I went into property builder and defined a
hyperlink column bound to title. In this dialog is a choice to convert to
a ItemTemplate. You can pretty much do what you want at this point.
Above, I passed the title_id and pub_id in the query string.

Let me know if you have any questions. Hopefully this is what you are
after!

Enjoy,
