Binding Random XmlDataSource To A Repeater With Xpath?
Jan 18, 2011
I'm creating page to put together a list of cinema trailers on an asp.net web page inside of a repeater.
The source of the data is an online XML feed.
To do this I'm binding the repeater as follows...
string XML_FEED_URL = "http://some-cinema-feed.com/comingsoon/";
XmlDataSource data_source = new XmlDataSource();
data_source.DataFile = XML_FEED_URL;
data_source.XPath = "/movies/movie[position() > 0 and position() < 3]";
this.moviePreciewsRepeater.DataSource = data_source;
this.moviePreciewsRepeater.DataBind();
The issue is that the length of the feed changes regularly and rather than selecting a range of movies with the XPATH (i.e. 1-3 in the XML) I need to select 3 totally random movies from the XML and bind this back to the repeater.

I have a traffic rss feed which I want to filter when a user enters some text in the text box. For example, if the user enters “Leicester” in the search box then only data containing “Leicester” in the “Tile” OR “Desscription” with be displayed.
<asp:DataList ID="dl_traffic" runat="server" DataSourceID="Xml_1" style="font-family:Arial;font-size:14px;margin-left:2px">
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<SelectedItemStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<AlternatingItemStyle BackColor="White" />
<ItemStyle BackColor="#EFF3FB" ForeColor="Black" />
<HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
<ItemTemplate>

What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")

I have a repeater that is looping a user control, like this:
<asp:Repeater ID="repItems" runat="server" EnableViewState="false"
OnItemCommand="repItems_ItemCommand">
<ItemTemplate>
<dmg:confirmItem runat="server"
[Code]....
All works brilliantly the first time around, the basket items are bound to Basket objects and everything is great.
However, when I receive an ItemCommand from my repeater, and update the basket contents (Note: No adding or removing is done here, just updates the quantity) then I rebind to see the latest values, and BOOM! Null reference - no Basket object in the user control Page_Load. This is despite tracing through to see that the BindItems() method is called as usual, and the Baskets are there.

I am in situation where I need to bind multiple types to a single repeater.Say for example I have 2 types in different namespaces
abc.businessLayer.Type_A [properties - Name(string), Country(string)]
xyz.businessLayer.Type_B [properties - FirstName(string), Location(string)]
Now I need to bind the repeater with the combined results of above 2 type collection with the repeater column names "Full Name" and "Country".I am planning to add a new Type_C.cs in the application layer and iterate the A and B type collection to assign the properties in C and finally bind the repeater with Type_C.Can someone let me know if there is better way to go with such kind of issue?

I use a label for sending my html data to the view(ASP.net.). Below you see a short version of my code-behind page:
[Code]....
This practice is in my eyes not the best one. The html-code is much bigger in the real situation and I don't like that in my code-behind page. I would only send the image source to the view and bind them in some ASP.net tool. I think the ASP.net repeater is the best. But I have no idea, how to do this?

I have this array: string[,] productData = new string[5,7];
I bind it to a repeater and a call a method like: <img src="<%# getPhoto1WithReplace(Container.ItemIndex) %>"
Which is defined like:
public String getPhoto1WithReplace(Object itemIndex) {
int intItemIndex = Int32.Parse(itemIndex.ToString());
if (productData[intItemIndex, 3] != null) return this.ResolveUrl(productData[intItemIndex, 3].ToString());
else return String.Empty; }
I do not understand why it calls getPhoto1WithReplace with itemIndex as 5. My array has 5 indexes: 0,1,2,3,4, so How Container.ItemIndex can be 5?

I've had a bit of a problem trying to bind a generic list to a repeater. The type used in the generic list is actually a struct.
I've built a basic example below:
[code]....
I then create two fruits using the struct (apple and orange). These fruits are then added to the list.
Finally, I bind the generic list to the DataSource property of the repeater...
The markup looks like this:
[code]....
I expect to see the fruit name and price printed on the screen, separated by a horizontal rule.
At the moment I am getting an error relating to actual binding...
**Exception Details: System.Web.HttpException: DataBinding: '_Default+Fruit' does not contain a property with the name 'FruitName'.**

I have a couple of Checkbox controls in the Item Template of a Repeater and am trying to set them (checked or not) based on an underlying data value. With Labels the <%# Bind... > syntax can be used but there does not seem to be an equivelent for a Checkbox.
So I have moved into the code, specifically the ItemDataBound handler of the Repeater control but cannot seem to instantiate the Checkbox controls.
In the handler repProjectList_ItemDataBound(object sender, RepeaterItemEventArgs e) I can instantiate the Repeater by casting sender or the RepeaterItem by using e.item and both have FindControl() methods but neither seem to find my Checkbox.
Further, once I am able to 'find' the Checkbox, I'm not sure how to reference the various values in the underlying data source.

The title pretty much explains it. I want to bind a single item to a detail type control. I can bind to a repeater perfectly fine and obviously only one item will be displayed. It seems like there would be a better suited control for this. I know about FormView and DetailsView but they both generate a table which I don't really want. Something similar to the Repeater since it doesn't generate any content other than what you put in the template.

i have a database of values that I am rendering in a table via the repeater control. (Previously I was using a gridview but I know require a repeater) I have a checkbox being 'repeated' for each record and I can get the id of each row to do some logic, but what I cannot get is whether it is checked or not as the value is null. As the database has no null values, I can only asume it is not binding for the checkboxes as current true values do not have a check in the box. The onCheckedChanged event carries out the logic required to change whether record is disabled via the database. With a gridview
Checked='<%# Bind ("Disabled")%>' was enough
<td
class="GridCentre"[code]....
is this done with the itemdatabound event? and how is it done?

I am attempting to bind a Repeater (but it could be a GridView or ListView) to a list of objects. The List's type is an abstract type, which has two different classes derived from it, both with different properties. Because they have different properties, I cannot just have one ItemTemplate. If I bind a control to a property of one type of class and the other type doesn't have it, it throws an error.
Here's where I'm at:
I cannot use <% if (whatever) { %> some stuff <% } else { %> some other stuff <% } %> because I cannot access the databound item to make the choice based on its type. I cannot use the <%# %> syntax, which lets me use the databound information, because you cannot code logic like if...then...else. I cannot (rather not) call a function and return a string with the code because what I want to render is complex and contains further nested databound controls. Has anyone found an ingenious way of doing if it is this type of object, display these controls, else display these other controls?

I've been using a repeater to build a website's site map page by binding to the web.sitemap file. For example, to display 2 levels of links:
[Code]....
So far, everything works well. However, in some cases, I do not want to display certain pages in the site map. I've added a custom attribute to each node (nodisplay= 'true').How can i check for this attibute, and avoid it from being displayed by in the repeater.

I have this DropDownList bound to a XmlDataSource, but the XPath must depend on another input (another DropDownList). I modify the XPath and rebind inside the parent DDL's SelectedIndexChanged, but the page does not refresh. What should I do to display the update?
protected void ProductDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
CompMapping.XPath = "//couple[@product='" + ProductDropDownList.SelectedValue + "']";
CompMapping.DataBind();
ComponentDropDown.DataBind();
}
ComponentDropDown is set to AutoPostBack=True, but that's not enough. Could it be related to the fact both DropDownLists are in a UserControl?

have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>

I am Trying to build a Treeview Control using an XMLDataSource which consumes a XML file (which is set dynamically) . The Problem is that the XML file Size is huge, arround .5 MB so the page load is hit because of this . Now i know that there is a PopulateOndemand Property of the treeview and there is also a populateondemand property of Treenodebinding which is used in XMLDataSource .
