Forms Data Controls :: Dropdownlist In The Edit Template

Aug 24, 2010

I have a transaction table with a field called product. There is a limited number of choices for product so I also have a product table. I am showing the transactions in a ListView with a dropdownlist for Product. The field Product can be blank (all works well then). The user can leave the field blank or they can choose from the dropdownlist. I am running into a problem with the dropdownlist in the Edit Template. No matter what the product is in the transaction file, I get a page error of "ddlEditProduct has a SelectedValue which is invalid because it does not exist in the list of items". I have verified the product does exist in the product table.

<asp:DropDownList ID="ddlEditProduct" runat="server"
DataSourceID="dsProduct"
DataTextField="Product"
DataValueField="Product"
AppendDataBoundItems="true"
SelectedValue='<%# Bind("Product") %>' >
<asp:ListItem Selected="True"></asp:ListItem>
</asp:DropDownList>

C# - Filter Subcategory Dropdownlist Inside Editable Template Of Listview / Formview

Aug 20, 2010

In my listview object insert/edit template, I have two dropdownlists (category, subcategory). When a user selects a category (autopostback), I would like the subcategory dropdown to filter to only the those that match the categoryID from the category ddl. This seems to be complicated by the fact that it is in a listview object. I'm currently using a queryextender on the subcategory datasource, but I'm not sure how to apply the selectedvalue of the category to the queryextender. The subcategory just shows all items and is not filtered. How do you accomplish this?

Forms Data Controls :: Get Dropdownlist Parameter Value From Different Template Field In Detailsview

Mar 22, 2010

I've been struggling with trying to figure out how to do this for about 2 weeks now. I have a DetailsView with several template fields in it. The first field (Unit_Code) is a dropdownlist item where the user would select a Unit based off the Unit_Code's Unit Name. Further down I have a field named (System), system needs to get it's value from the selectedvalue or selectedindex that the user selected in the (Unit_Code) dropdownlist. I have another dropdownlist item (Component) that will need to get the selected value from System to sort on, so once I have the first Unit_Code to System figured out I should be able to figure out the System to Component part seeing as it will basically be doing the same thing.

My aspx page code is below:

AJAX :: Dynamic Data - DropDownList Field Template With Cascading DropDown Extension?

Sep 10, 2010

Have spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension.Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated. The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values.Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :)Attribute I created:

Forms Data Controls :: Dropdownlist In Edit Template, In Detailsview. Getting "SelectedValue Does Not Exist In List?

Jun 7, 2010

I have a standard gridview and detailsview. My detailsview has some fields which are templates, with dropdownlists. The user selects a record in the gridview, then can go down to the detailsview, select Edit, and change some values (using dropdownlists).I am getting the error, "DDL has a selectedvalue which is invalid because it does not exist...." when I click Edit in the detailsview.

I know the problem has something to do with the dropdownlists not being instantiated or bound until I enter Edit mode. Is that right? In what event should I databind my dropdownlists? I've tried several things but could not get it to work. Do I have to loop through all the rows of my details view looking for the dropdownlists, or can I access them directly from some event?

Web Forms :: How To Show Different URL's On The Same Page Using Dropdownlist

May 23, 2010

I have an .aspx Page with dropDownList, where you can choose State. The list contains 50 States. Then I have a GridView displaying all the stores of this particular state, which is dependent on dropDownList through the SQL Data Sources WHERE clause.

But the problem is, every time I change the State in the dropDownList and subsequently refreshing GridView - the page URL stays the same dealers.aspx.

I don't want to create 50 pages for 50 States, but now I need to have 50 different URL's. Is there a way to change URL's dynamically, based on dropDownList choice? And so people can get directly to URL of choice. For example dealers.aspx/California.
