I have two comboboxes say DDL 1 : Artist , DDL 2: Albums and a Gridview containing ( album name, artist name, no.of tracks, year, etc), What I want to achieve is: when an option(artist1) in DDL1 is chosed, then the albums related to DDL1 needs to display in DDL 2 and also it must update the appropriate values in the gridview( artistname, albums(album name -no of songs, year)etc...(language: Asp.net(VB)-Sql server ).

I am trying to bind a DropDownList inside a repeater control to an existing data set (to be able to edit the data) and I have been searching for an answer to this problem for a day and a half now without any luck.
View 19 RepliesI am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.
I also read this article [URL] but still can't understand how to bind dropdown in a repeater.
I want to display 2 things inside the Repeater Control.
1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.
2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)
Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.
Here is my code so far ....

I'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void

I have bootstrap accordion and it is inside repeater,
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate>
Employee Name: <ul><%# Eval("Name") %></ul>
[Code]....
There is one employee, so the first two accordions is working fine from toggle up and toggle down
SCENARION 2:
There are 3 employees, for the first employee the first two accordions is working, but the rest are not.
So the problem here is when I click the accordion of second employee it does not toggle down but the first employee's accordion is going down.
What I want here is each employee can toggle down and toggle up their own accordions, even though that accordion don't have data.

Asp.net 3.5 using code behind I am using a repeater control. My datasource appears in code behind. I decided to NOT have my listitems populate from the database. I want the user to select a value, send it to the database via an update statement, and then when the user returns to the page (on pageload), have the user's previous selections appear on the screen. note the following:
When I use textboxes and labels, ALL of my data appears within the table of the repeater control. However, when I replaced one of the text boxes (originally used for testing purposes only) with a dropdownlist, I get the following error message'ddlDDuring' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value My Repeater1_ItemCommandI updates the data within the repeater perfectly. On page load, I want the data from the database to display as the dropdownlist's selected value (or selected item.text). Here is my Asp code
<asp:Repeater ID="Repeater1" runat="server"
onitemcommand="Repeater1_ItemCommand">
---
<
td><asp:Dropdownlist ID="ddlDDuring" runat=server SelectedValue ='<%#Bind("DueDuring")%>' >
<asp:ListItem Value="-select-" Text="-select-" />
<asp:ListItem Value="1st half" Text="1st half" />
<asp:ListItem Value="2nd half" Text="2nd half" />
<asp:ListItem Value="Split" Text="Split" />
</asp:Dropdownlist> </td>

I tried the following code changes on asp page: I changed "SelectedValue" to "Text" and still get the same error message I changed "SelectedValue" to "SelectedItem" and don't get the error message, but dropdown is not populated I set AppendDataBoundItems = true Set first list item value = "" Verified that every field in the table column matched the items in the dropdown list. There were NO null fields in the database.
I just want to understand this error message, as I have exhausted all that I am doing. I also made an attempt to bind the dropdown list, but sine this can only be done within the loop of finding the repeater control, I would either get an error message, or it just would not work.

I am using jQuery to do a cascading dropdown list (State, City). In order to pull the information from the database I have a web service that I reference. The code all works like a champ when I use the JavaScript on the ASPX page for proof of concept, but when I place the JavaScript in the userControl and then put the userControl on the ASPX page, it breaks.
The next foreseeable thing that will potentially complicate things further is that the userControl will be inside of an updatePanel
I have a user control inside a repeater. I am binding a collection of objects to the repeater.
My user control has a public property to retrieve the object (setobject)
How do i pass each object through to the user control and not just the object property value? What is the syntax to do this?

I have a composite control inside a repeater. I am trying to set the controls public properties inline like so (this is a simplified example):
<uc1:Control runat="server" ID="id" Value='<%# Eval("value") %>'>
When I place the repeater inside a user control INSIDE ANOTHER user control and onto the page this works - the property is correctly set, if I inspect it inside the EnsureChildControls() method of the custom control the composite control's Value propertyis set to Eval("value") as intended.
