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:

KlantMetaData (=> Klant is Dutch for Customer ):

DynamicDropDownList Control I created:

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

Forms Data Controls :: Cascading DropDownList In DetailsView Field?

Feb 9, 2011

I have an ASP.NET/C# web project that uses an Entity Data Model and Entity Framework to interact with my database. I also have a DetailsView control that will serve as the control used to insert a new record. The user will need to be able to select from multiple,
cascading dropdownlist controls to determine what parent record this new record will belong to. Here is an example.Say we have an online ordering system with the following hierarchy.

Customers -> Orders -> OrderParts -> Parts

We're going to add a new part to an order, under a customer. Ultimately the orderparts table won't have a reference to a customer, just an order. The order will have the reference to the customer. In the DetailsView for the new orderparts record we will need two cascading dropdownlist controls. One for customer and one for order, since we won't want to view some crazy amount of orders all in one dropdownlist.

However, the customer dropdownlist should not be bound to the detailsview control since there is no field for it. I also don't want to use the AJAX control since I don't want to create a separate web service to provide all of this information to the dropdownlist controls.

Forms Data Controls :: C# Dynamic Gridview Using Template Field As Control?

Mar 31, 2010

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.

After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

Forms Data Controls :: Dynamic DetailsView - Adding Template Field By Code?

Feb 11, 2010

I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.

Below is my sample code:

[Code]....

the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:

Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.

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:
