I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?
I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
DDL3.Items.Insert(0, new ListItem(" please select ", "0"));

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

I have a dropdownlist attached to a cell when edit is selected. I am using the following code to populate the drop down list with the value that is on the row.
dlBU.Items.FindByValue((e.Row.FindControl("lblBU") as Label).Text).Selected = true;
This works famously when I have a value in the cell. It fails when the cell has not yet been populated. Is there an if then clause that if the value of e.Row.findcontrol("lblBU") is null no default value?
I'm using a DropDownList with a data source which successfully populates the list. However, I want one of the items to be selected, namely the one where the value matches the path and query of the current request.
Using the debugger in Visual Studio 2008 reveals that item.Selected becomes true exactly once in the loop, but the rendered select has no option that is selected.
I'm using Visual Studio 2008 version 3.5. I have a dropDownList with over 800 names. The user wants to be able to type in it and select the name. I have seen this functionality in Telerik combobox but do not have license. How this functionality can be accoplished?

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
I need to the display the ddl as Select Type and when i click the dropdownlist to see the values in it, it should display the three values, but i should not use Select Type as a list item and it should not be displayed in the list. It should only be used as a default text in ddl.
Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:
In a gridview i have a TemplateField containing a radioButtonList. I have around 100 rows with data and each radiobuttonlist has around 5 options. I would like to have the user to select an option from the radiobuttonList and then in my button click event to record the selected value of the radiobuttonlist for each row. The area im struggling with is how could the click event of my button send the selected value for each row?

I have a form with two GridView controls and a FormView control. All the data is populated using a SqlDataSource for each control - I'm not using any code behind to populate the controls. So far so good. The first GridView is called grdTrades with code like this:
[Code]....
At the moment when the page loads, the frmOrderDetails FormView is not populated. The user has to click on an order in grdOrders to populate the FormView. Is there a nice way to do this?
I have a gridview with two columns (item templates) one is a dropdown and the other is a textbox. I need to select an item from the dropdown (which I can do) and then get the cost of it and then put the cost in the texbox item template of the gridview. So I think I need to pass the row number and cost_id of the selected item to a procedure to get the cost of the item. Here is my so far code that I have now Idea how to pass the values of the gridview and then pass the cost of the item back to the proper row and textbox of the girdview.
I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.
