Multiple QueryString Parameters with NavigateUrl in Hyperlink inside a GridView in ASP.Net

Hi Priyanka88,

Try the following..

Html

 <asp:GridView ID="gvPersons" runat="server" AutoGenerateColumns="false" >
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <a href='<%#Eval("Url")+"?Id="+Eval("Id") %>'>
                            <%#Eval("Id") %></a>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

Code

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                this.gvPersons.DataSource = this.GetData();
                this.gvPersons.DataBind();
            }
        }

        private DataTable GetData()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("Id"));
            dt.Columns.Add(new DataColumn("Url"));
            dt.Rows.Add(1, "WebForm1.aspx");
            return dt;
        }

 Explanation:-

<a href='<%# "Eval("DetailedPage")?ID="+DataBinder.Eval(Container.DataItem,"ID") %>' style="text-decoration:none; font-size:small; color:#22BCE5; font-weight:bold">View More...</a></td>

Here you have kept the Eval part in double quote means it will be treated as one string like-"Eval(".

Second string will be as ")?ID=" so that DetailedPage(Which is your databinder part) will be left with nothing.

So remove your double quote form eval and try as i posted
