Body
I'm trying to make a button inside templatefield in gridview run a function and send eval based on one of the fields. already tried several methods, but could not make it to do the job. I have a mssql database which contains info about files uploaded and paths to these files. I would like to add a button to each row that will allow me to download the specific file by it's path. this is the sqldatasource and the gridview: <pre><code> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:igroup20_test2ConnectionString %>" SelectCommand="SELECT [f_name], [f_date], [f_description], [f_path], [f_num] FROM [uploaded_files]"></asp:SqlDataSource> <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="False" > <Columns> <asp:BoundField DataField="f_name" HeaderText="Name" SortExpression="LastName" /> <asp:BoundField DataField="f_date" HeaderText="Date" SortExpression="FirstName" /> <asp:BoundField DataField="f_description" HeaderText="Description" SortExpression="Title" /> <asp:TemplateField HeaderText="download"> <ItemTemplate> <asp:Button ID="btn" runat="server" CssClass="btn btn-primary" Text="Download" OnClick='<%# Eval("f_path", "download_file(\"{0}\");") %>' /> </ItemTemplate> <ItemStyle HorizontalAlign="Center" /> </asp:TemplateField> </Columns> </asp:GridView> </code></pre> this is the code behind function: <pre><code>protected void download_file(object sender, EventArgs e,string val) { filename = "Server side exc 2PLATINA.JPG"; string path = val; Response.ContentType = "application/pdf"; Response.AppendHeader("Content-Disposition", "attachment; filename='someName'" ); Response.TransmitFile(val); Response.End(); } </code></pre> another small interesting thing, how come there is no exception about the multiple buttons with the same id?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
