I have been working on Rss Feed project for quite sometime now, i am trying to dynamically populate a repeater with corresponding description when a title is clicked. here is my code:

XML

        <asp:XmlDataSource ID="XmlDataSource1" runat="server"
                DataFile="http://www.channelstv.com/home/feed/"
                XPath="rss/channel/item[position()<6]">
            </asp:XmlDataSource>
                <br />
             <asp:Repeater ID="Repeater1" runat="server" DataSourceID="XmlDataSource1" >
            <ItemTemplate>

           <a href="Default.aspx?News=<%# XPath("title")%>"><%#XPath("title")%></a> <br />--%>

                 <%#DateTime.Parse(XPath("pubDate").ToString()).ToString("MMMM dd, yyyy")%>
                 <hr style="color:#0099ff;" /><br />
            </ItemTemplate>
        </asp:Repeater>

the above code will display 5 feed title and publish date, i want to be able to display corresponding description for each title on another page when any of the link is clicked. Please idea will be appreciated. Thanks in advance.

So, what is the issue?

Uwakpeter 10-Jan-14 12:49pm

This my code will display five feed title as links, when a user clicks on any of the feed title, he or she will be redirected to Default.aspx, I want to be able to display the feed title that was clicked and corresponding feed description on Default.aspx. Thanks.

So, is it not reflecting the values in Default.aspx page for every link?

Uwakpeter 10-Jan-14 23:28pm

Yes sir, I want to display description that comes with each title on Default.aspx

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 11-Jan-14 1:05am

Check the HTML of the page and see what is the href value showing on each link.

Uwakpeter 11-Jan-14 10:39am

these are the href value for each link:

href="Default.aspx?News=Celebrations In Central African Republic After Leader Resigns"
href="Default.aspx?News=Bayelsa Government Upholds Demand For More Power Stations"
href="Default.aspx?News=Nigeria’s Economic Policies To Aid Customs’ Performance – Okonjo-Iweala"
href="Default.aspx?News=Over 165 Terror Suspects To Be Released On Presidential Directive"
href="Default.aspx?News=Navy Chief Warns Warri Warring Factions".

Also i want to be able to replace the whitespaces within the string with a dash, any assistance on this will be appreciated. Thanks in Advance

As the href seems to be different for each link, so problem is in Default.aspx page.
So, can you show me how exactly you are reading the value in that page?

Also no need to replace dash for the spaces, rather use HttpUtility.UrlEncode Method (String).

Uwakpeter 11-Jan-14 11:28am

the white spaces are showing as %20 on the url, i want to replace the %20 with dash so it could be optimized for search engine.

On default.aspx i am reading the query string like this:

<%#Request.QueryString["News"].ToString()%>

but it doesnt seem to display, and i dont know how to display the corresponding description alongside with each title. Thanks

Uwakpeter 11-Jan-14 11:41am

and also how can i use the HttpUtility.UrlEncode Method (String) with the query string within the repeater item template

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 11-Jan-14 23:19pm

<a href="Default.aspx?News=<%# HttpUtility.UrlEncode(XPath(" title="))%>">

You can encode like this.

About showing the description, you are not sending the description to that Default.aspx page, you are sending only the title. You should send description too.

Uwakpeter 12-Jan-14 6:06am

You didn't show how to encode. I have added a label for the descriptionlike this: <asp.Label ID = "desc" runat="server" text ='<%#Xpath("description")%>' Visible="false"> Now my question is: how can I access the text property of the desc Label on Default.aspx and databind it to a repeater control?

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 14-Jan-14 10:48am

See it carefully...

<a href="Default.aspx?News=<%# HttpUtility.UrlEncode(XPath(" title="))%>">

I have included the HttpUtility.UrlEncode() inside the href, which I have already mentioned in my previous comment.

Uwakpeter 15-Jan-14 6:16am

yes it works but it is using plus sign, is there anyway i can encode with a minus sign or dash?

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 15-Jan-14 6:38am

No, you can't do that directly.

But you can do like...
1. How does Stack Overflow generate its SEO-friendly URLs?[^]

OR

Just replace before encoding like...

<a href="Default.aspx?News=<%# HttpUtility.UrlEncode(XPath(" title=").ToString().Replace(" ", "_"))%>">

Do you understand this?

Uwakpeter 15-Jan-14 6:47am

yes that works also, Thanks. But still having non alphanumeric character like(-,:%&) not being replaced in the string. could this be handle as well? Thanks so much.

please could u still help? still could not get description on pageload, i have been able to get the text using:

public string text = "";
Label label = new Label();
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) // Add this
{
label = e.Item.FindControl("Desc") as Label;
text = label.Text;
}
}
I tried getting it on page load like this: disPanel.Controls.Add(label); but no success!

Solution 1

The solution for this is already in your code.
Put a label somewhere on your Defailt.aspx page and get the title from the query string like this.

Request.QueryString("News")

Yes I have been able to display the title and description Default.aspx using the querystring, but it is only the first title and corresponding description that always displayed, I want to be able to display such that the title and description will change on every link that is clicked. Thanks...

No, you can't do that directly.

But you can do like...

OR

Just replace before encoding like...

JavaScript

<a href="Default.aspx?News=<%# HttpUtility.UrlEncode(XPath(" title=").ToString().Replace(" ", "_"))%>">

If you want to use Replace some characters again, then you can do like...

C#

HttpUtility.UrlEncode(XPath(" title=").ToString().Replace(" ", "_").Replace("CharacterToReplace", "NewCharacter").Replace("CharacterToReplace", "NewCharacter"))

Use as many times you want. :)
