Forms Data Controls :: Detailsview Edit For Cascading Dropdownlist

Mar 2, 2010

I have created two dropdown lists. The 2nd DDL depends for values on the 1st DDL. I have written code on the SelectedIndexChanged event of 1st DDL to change values of 2nd DDL. also i have used detailsview. In the template field i have used 2 DDL mentioned above. they are having SelectedValue='<%# Bind("") %>' property. Everything works fine but when i tried to edit record in detailsview & select value from 1st DDL then it gives me following error.

Server Error in '/' Application. Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

May 10, 2012

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 looked at your article regarding cascading dropdownlists and was really useful but in my case I want to use two drop down lists and a grid view.

Forms Data Controls :: Gridview With Dropdownlist Edit / Getting An Error

Jan 6, 2010

I have create a grid view with a dropdownlist for one of the columns. This works fine, but when I click edit and then update I get an error saying it cant update due to null value.

Forms Data Controls :: GridView Edit Fails On DropDownList

Jun 30, 2010

I have created a Gridview (using ObjectDataSource) for Edit/Updates. I am getting an error on my DropDownList which is configured with the list items Yes and No only for both text and values.

Most of my data in my SQL table has values of either Yes or No, however there are some records that are BLANK or even NULL sometime.These rows fail in my GridView when attempting to Edit.

I tried going into the DDL Edit List items and adding a Blank with and empty value however each time i try to save the page VWD removes it.

How do i account for reverse lookups of all possible values Yes/No/Blank or Empty/NULL in my DDL?

Data Controls :: Populating DropDownList In Edit ItemTemplate Of GridView?

Aug 29, 2013

I read your article on ASPSnippets and everything worked great.  I am having one problem and this is preventing me from moving forward.  When I select the edit for a row (I only have two columns), the drop down comes back blank (no records).  I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list?  I can't tell if the column automatically adjusts because I am not returning any records.

Forms Data Controls :: Implement A Form Of Cascading Dropdownlists And Associated Controls?

Dec 4, 2010

I've got 3 SqlDataSource controls, and 2 dropdownlists and 1 detailsview on a page. The first SqlDataSource is associated with the first dropdownlist, and second SqlDataSource (which is filtered based upon the selection chosen in the first dropdownlist) is associated with the second dropdownlist and the third SqlDataSource (which is filtered both by the selection of the first dropdownlist and the second dropdownlist) is associated with the detailsview. The idea is the user selects something in the first dropdownlist, and it is supposed to update what is returned by the second SqlDataSource control and second dropdownlist, and that in turn is supposed to change what is returned in the third SqlDataSource control and it's associated detailsview. All of the dropdownlists have AutoPostback set to True.
