The problem is that i have a search page. Access Database holding the information. I have a Access Datasource on the page with a Datalist to show the data. I need to find a way on setting it up to says "Sorry no results found" when the is no results. i am unsure on how to do this though.
Below is my datasource and datalist
[Code]....
How can i refresh(Asych) the contents of my Datalist on the parent page from a data change in a page that is displayed in an iFrame on the parent page.
I have movie names with image in the data list that is on parent page.
there another page is openend in the parent pages in an iFrame control.
in that sub page i upload image and other data related to a new movie.
What i want is that when i submit that information in an iFrame page, the DataList should update(Asych) itself on the parent page showing new updated info.
the structure is like;
[code]...
I have several datalist controls inside a panel control.
When I do a databind on the "movie" datalist, data is populated. I can see during the debugging on the aspx page that it goes into the label controls and binds the data.
When I do a databind on the "alacarte" datalist, the data isn't populated even though before doing the databind I validate that there is a record inside the generic collection that I use for each separate type of datalist. When the databind occurs, it goes thru the alacarte datalist and does the databinding to the fields, but when the page renders, it doesn't produce any output inside this datalist.
The code behind below is the databinding for the movie datalist.
DataList grdMovies = ShoppingCart1.FindControl("grdMovies") as DataList;
grdMovies.DataSource = lstMovies;
grdMovies.DataBind();
The code behind below is the databinding for the alacarte datalist. I verified that there is a record inside the lstAlacarte collection with the same field names that are in the html for the alacarte section during the databinding.
DataList grdCartAlaCartePgming = ShoppingCart1.FindControl("grdCartAlacartePgming") as DataList;
grdCartAlaCartePgming.DataSource = lstAlacarte;
grdCartAlaCartePgming.DataBind();
Below is the html on the aspx page for the above controls. I included all of the html so as to see if there is anything I'm doing wrong. I even placed the words "desc" and "price" to see if that would render and it did not.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ShoppingCart.ascx.cs"
Inherits="DishRedesignClient.ShoppingCart" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="cc1" %>
<asp:Panel ID="pnlShoppingCart" runat="server" Height="400px" Width="300px"

I have a datalist and the following link button within the datalist:
[Code]....
I would like to post to a new page and then capture the value from the link button (commandArgument). It appears from other threads I've seen that you have to rebind the datalist in order for the ItemCommand event to fire...is this true? I'd hate to make another DB call to bind my datalist just to make an event fire.

I have a datalist inside 1 datalist.In the first datalist i am binding the "advertisement posted" date field from sql server. In the second datalist i am binding the ads posted on that date using an object datasource. my pro is, i need to show a total of 100 ads in one page. This should not depend on the date. Total 100 postings in the page. For example
Todays date (02/25/2010)
50 postings
yesterdays date (02/24/2010)
if 75 postings are there,
50 postings
it should display only 50 postings under yesterday's date remaining 25 postings should display in next page(paging) with the format like this
yesterdays date (02/24/2010)
remaining 25 postings
(02/23/2010)
75 postings
how can i do the paging like this?
I am using Eval inside a datalist to populate a hyperlink within the datalist with a navigateURL value and I am using it as follows:
<asp:HyperLink ID="HyperLink_FullStory" runat="server" Text="Full Story" NavigateUrl='<%#Eval("LinkAddress")%>'></asp:HyperLink>
The issue I am facing is that the current page URL is getting appended to the 'LinkAddress'(the URL being fetched from the database) and thus,the final URL formed is not a valid one.Can someone suggest how do I remove the current page URL? Is there any way it can be done without writing code in the code behind page?

I've got a few labels in a datalist that are being populated based on the values of a queryString but without the query string the datalist is empty.

I have a rather large datalist on which I have implemented an editing capability. When I click on my edit link, everything works as expected except that when I bind my data focus returns to to the top of the screen, so my user will have to scroll all the way back down to the item he wants to edit. Is there a way to keep the page centered on the item in question through the databind?
