Web Forms :: How To Use The Repeater For Binding Images For A Photogallery
Jan 21, 2010
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?

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 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.

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 a repeater that is looping a user control, like this:

OnItemCommand="repItems_ItemCommand">
<ItemTemplate>
<dmg:confirmItem runat="server"

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 have tried binding images to repeater from one folder called images . But now, I am trying to bind the repeater with different folder's images, based on which menu item is clicked like "Wedding", "Birthday". When "Wedding" is clicked then it repeater should be loaded from Wedding folder's images similarly with "Birthday".
Currently i am using following code to load from single folder.
if
{
Repeater1.DataSource = di.GetFiles();
Repeater1.DataBind();
(!IsPostBack)string imgDir = Server.MapPath("~/images");DirectoryInfo di = new DirectoryInfo(imgDir);

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'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 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'.**
