I want to place a image with the text "NO IMAGE" in my Repeater when there is no image.What changes must i make in order to achieve this? I want my Repeater datasource to point to an image inside my IMAGE folder in my root directory.

In the code behind I have a function that returns a List(Of SomeClass):
rptRepeater.DataSource = SomeFunction(SomeVariable)
rptRepeater.DataBind()
In the html I have a basic repeater layout and am using the below code to get the Properties of each object returned.
<%#Databinder.Eval(Container.DataItem, "Parameter1")%>
My question is, would there ever be a case that it would execute the Function more than once?
I have a Repeater Control which I bind to a list of Products
Repeater.DataSource = ProductRepository.GetProducts();
Later (in another module), I need to retrieve the products from the Repeater, but it seems not to work with Repeater.Item.DataItem (which is then null).
My question is, is there any reference to the products in the Repeater-Items? Or do I have to set it myself via id field etc. What would be the easiest way to get the "underlying" product objects?
I have an arraylist:
[Code]...
I know how to use <%#Container.DataItem%> to dump everything but I need to get at the items in the array individually, not have them all ditched out to the page in one go. For example, item 1 contains a link, item 2 contains an image path, item 3 contains a description. I need to have them kick out in the correct order to build the link and icon correctly.
Im a ASP.NET beginner. I previously asked how to do some databinding to a repeater without a datasourse.

I have a treeview on this page of which each node has and Id and value. on selected node change event, I want to change the text of repeater selected node. I am writing code like this:
Protected Sub TreeView1_SelectedNodeChanged(sender As Object, e As System.EventArgs) Handles TreeView1.SelectedNodeChanged
Dim EmployeeRepeater As Repeater = CType(Me.Form.Controls(1).FindControl("Repeater1"), Repeater)
Dim EmployeeRepeaterItem As RepeaterItem

But It is not chagging MyLabel text. How to fix it ? Both treeview and repeater are populated in !Page.Ispostback event?
I'm trying to make my datagrids datasource change when you select a particular item from a drop down menu but all I get is blank cells! any ideas? I don't think it is changing the colums property automatically either.
If chooseType.Text = "Add / Edit Players" Then
updateDB.DataSource = PlayersBindingSource

I have a number of idential repeaters, and I need to iterate through all of the items. I currently have:
For Each item In rpt1.Items
.do some stuff
Next[code]....
Is there a simple way to reduce this to a single For Each ... Next loop?
Edit: There are a number of local vars involved in "do some stuff", which is why I can't just pass the item into a function - the call would have to include about 8 ByRef params.
I have created an application which uses an sql server connection as its datasource. The problem I'm having is that the application needs to work on computer that has no network connection. How Can i change the datasource so that on runtime it can work off a machine that is not connected to a network? The datasource from the sql connection only contains one table with no data. It only needs to be updated with a target folder that can be changed to any location on any computer already written in the code.
The connection string suddenly stands as: Dim MyConnectionString As String = "Data Source=MY-PC;Initial Catalog=ImageLocs;User Id=test;Password=test;Pooling=False"
In a windows forms project, I have several combo boxes. The first combo box contains a list of objects. Those objects then have several lists which are used as the datasource's for the successive combo boxes, depending on which item is chosen in the first.

I am using VB.Net with Framework Version 2.0.
I am trying to refresh my combobox when an item is selected and added the highlighted code as shown below; [code]Items collection cannot be modified when the DataSource property is set.
View 3 RepliesI have a small requirement and that is as follows:
I am populating a ListBox using stored procedures and the ListBox is populated as follows:
lstItems.DisplayMember = "emp_name"
lstItems.ValueMember = "login_id"
lstItems.DataSource = accessFunction.getEmployees
The ListBox gets populated correctly. After it is populated, i have a CommandButton and on the click event of the button, i want to remove selected items from the ListBox. So in the click event of the CommandButton, i have written the following code:
lstItems.Items.Remove(lstItems.SelectedItem)
After selecting an item from the ListBox and when i click the CommandButton, i get an error as "Items collection cannot be modified when the DataSource property is set".
how i can delete items from the ListBox.
I have a combobobox on my form, and I use the following code to populate the data from SQL Server:
cbname.DataSource = DSAssetName.Tables(0)
cbname.DisplayMember = "IDWLNAME"
cbname.ValueMember = "FIDWID"

I am trying to use datasource and bind in my application to set a dropdown list to the results of a query. The dropdownlist populates correctly (shows each different type_name in the set) but later when I use ddltype.selectedvalue - I am always getting the value from the first item in the dataset. Here is the code.

I have two tables "Person" and "Alias" in a one to many relationship. I have a DGV for "Person" and want to use a combobox for the Aliases. I also have a textbox and a button for the user to type the alias name and click the button to add the alias name to the combobox and update the dataset. I keep getting the "Items collection cannot be modified when the DataSource property is set." Error. But if i use a DGV instead of a combobox for aliases, I have no errors and everything works fine. If I remove the datasource property for the combobox it will not get populated with the data already entered, so how, or can I, set it up where the combobox gets populated when the form loads and able to add items to the combobox????

I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
[Code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater
I have a parent repeater with nested repeaters.My problem is I am trying to use 'Next' and 'Previous' buttons to rebind my repeater (rptTabContent) and thus the inner repeaters also, but when I try to manipulate the state of these links during the ItemCommand event they are overwritten by the bind.
View 1 RepliesI have about 15 .RPT files on my .NET 2.0 site, and I recently changed to a new database server.I successfully changed the Datasource on 14 of those .RPT files, but on one, after making the change, I get "Failed to Save Document" when I try to save the updated report. I can change the subreport's Datasource, and save it just fine, but when I try to change the main report's Datasource I get that error message.I'm definitely doing a "Verify Database" at various times throughout the process, but that doesn't seem to help.
View 2 RepliesI am looking for a way (or an event) that works whenever I add or remove an item from a listbox. I was looking through the events and will give the textchanged event a try, but was hoping for something like a collectionchanged or itemschanged event?
View 3 RepliesHow do i change the values inside a listview after inputing some values from another window. The window with the list view doesn't close.

View 2 RepliesI have two combo boxes. box1 and box2 both on same form. Depending on what is selected in box1 will determin the items in box2. I would like box2 to change in real time (not pressing a button!)
Whats the best way to do this? use a timer on the form with lots of if else (or case) statments?
In my dialog I want to prevent the user to browse freely in certain places (this is due to the fact that my application will be running in a terminal server environment). So I want to to limit the items that will be visible in the top combobox of the server. I want it to start with "My Computer" instead of the usual "Desktop". Furthermore I only want to add mapped network drives under "My Computer" so that the user won't be able to see any local resources.With Spy++ I have been looking around at what happens when a FileDialog starts.
So far I have found that for each item in the combobox CB_SETITEMDATA and CB_INSERTSTRING methods are executed. By using a hook to the combobox I am able to intercept these messages, but sofar I am unable to determine the exact contents of what is inserted, so I am unable to determine wether it is the "Desktop" item or not.I have also discovered that the "My Computer" node is only added at the moment that the combobox is expanded. So I would need a way to get a handle to "My Computer" and insert an item for it manually
I am making a program that is in need of labels changing and showing depending on what the user clicks on a file Dialog.
Everything works fine except for that when I change the labels, it uses the entire file path, and I ONLY want the file name. How would I be able to get JUST the file name?
