Forms Data Controls :: How To Bind A DropDownList Inside A Repeater

Oct 29, 2010

I 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 ....

Forms Data Controls :: Retrieve Dropdownlist Value Inside Nested Repeater?

Jul 15, 2010

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?

Forms Data Controls :: Repeater Control Doesn't Bind Correctly After Editing?

Dec 20, 2010

I have a custom page (Page 1) in SharePoint where I have a repeater control. From Page1 I open Page2. This is where I generate a collection of object which i use to bind repeater control in Page1. For the first time everythings work fine. If I have 5 objects to bind, repeater control shows 5 elements.

Now assume, I have 5 elements in page 1. When I open page two It carried over same 5 elements. I delete 1 element and send 4 element as collection to Page 1. In page 1 after I databind the repeater control, it doesn't display correctly. It deletes the wrong element.

I debug my code. The collection which i am binding to repeater shows the correct elements. But while displaying i is not showing correctly.

Dropdownlist Inside A Repeater On Screen

Aug 10, 2011

I have a drop down list inside a repeater on a screen. I have no problems populating the list with all of the options at the time of binding. Everything works out fine EXCEPT the load time.

All of the options are there so it's fine. But my users would like me to fill the drop down list with the values at the time they click on the drop down list.

The repeater itself is inside an AJAX Update panel.

So I am trying to figure out how would I fill the drop down list with the actual values when they click on the drop down list inside the repeater inside the update panel?
