In one of the web page say "Default1.aspx" I have a Gridview.I am using 2 DataKeyNames in Gridview. i.e., DataKeyNames="G_Name, Param_ID" Also, I have one Hyperlink inside Gridview, upon clicking, page navigates to other page say "Default2.aspx"
code of "Default1" page:
<asp:GridView ID="GridView1" runat="server" DataKeyNames="G_Name, Param_ID" AutoGenerateColumns="False" Width="100%" PageSize="8" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField HeaderText="Goal Name" DataField="G_Name" Visible="false"/>
[Code]....
code of "Default2" page:
protected void Page_Load(object sender, EventArgs e) {
if (!Page.IsPostBack) {
string name = Request.QueryString[0].ToString();
string id = Request.QueryString[1].ToString();
}
}
I want to pass multiple parameters in querystring. I wrote above code.
Problem is: I am unable to write the correct syntax for Hyperlink NavigationUrlTherefore, it is giving me below error:
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'GF_Name, Param_ID'.
at Line:
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("GF_Name, Param_ID","~/Default2.aspx?Name={0}&Id={1}") %>'
Text='<%# Eval("GF_Name") %>'></asp:HyperLink>

We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...
