DataSource Controls :: Cascading DropDownList With LINQ?
Sep 8, 2010My application includes a gridview control with and Edit mode which allows users to do selections using cascading dropdownlist. My code is based on tutorial by Brian Orrell (link below). I am able to statically populate the dropdownlist but in my case I need to populate it dynamically based on a previous selection of a dropdownlist, I would like to do it programatically so I can manipulate data.

DataSource Controls :: Linking A FormView And DropDownList Together With SQL?
Jan 19, 2010I'm having trouble linking a form view I have on a web page with a drop down list on the same page. Basically, what I need to happen is whenever a new selection is chosen from the drop down list, the details in the form view should also change to represent that selection's criteria.
I have my drop down list connected to SQLDataSource1 and my form view to SQLDataSource2, and these are populating as expected, it's just the problem lies when changing the selection in the drop down list - the form view doesn't follow what is selected.
does anything have to be added in the properties options of either the data source controls or the form view? For example, in the "Events" section, there is a "DataBinding" and "DataBound" selection item that can be used - should anything be entered in this to connect the two?
PS - Here is the code I have in the back end of the page:

View 1 RepliesDataSource Controls :: Null Option In Qurery Parameters / Using Query With DropDownList And Textbox Controls?
Dec 18, 2010I have SqlDataSource with a few parameters (code below). If I understand this code correctly if parameter is NULL I should receive all items from the query. It works fine with query editor. But when I try to use this query on my page - with DropDownList and Textbox controls as source of parameters - it doesn't work. I suspect that main reason of problem is value which these controls pass to the query. Instead of NULL this is an empty string. Is it possible to pass NULL value from DropDownList or TextBox to
the SqlDataSource?

View 2 RepliesForms Data Controls :: Reload Datasource And Dropdownlist?
Jun 10, 2010i think i can't see the forrest for the trees.......there HAS to be a simple way to do this. so i created a web page and on that page i have two dropdown lists. the first is STATE and the second is COUNTY. the STATE is a static list. but the COUNTY is generated whenever the STATE changes. now....when i set up the COUNTY dropdown list, it prompted me for a datasource. i have a store procedure which takes the 2-letter STATE code and returns all the counties for that state. so i set up the datasource for the COUNTY drop down list by just following the prompts from visual studio. i gave it a default state of Alabama (AL). and all is fine. so here's my question: how can i reload the datasource and subsequently the COUNTY dropdown list? i see no way to access the datasource that the environment generated for me.
well.....i thought.......i'll just do it the old fashioned way and set up a command.......connectionstring.......and sql statement and load the results into a datareader (do i REALLY have to do all that?)
but it still doesn't work. what's the simplest way for me to just re-fire my stored procedure and pass it the STATE parameter and reload the datasource and dropdown list?
DataSource Controls :: DropDownList With Static And Dynamic Data?
Jan 8, 2010I have several dropdownlists which are databound to a SQL DB but I am also needing to add 2 items to them. I am using the code below.
With the code in the Calendar1_SelectionChanged sub (Which is when I want it to fire) It loads the data from the sql but not the static content
If I move the code to the Page_Load sub and add "If Page.IsPostBack Then" then it loads the static content but not the SQL.

View 2 RepliesForms Data Controls :: Connecting A DropDownList To A DataSource?
Jul 13, 2010I have a problem with connecting a DropDownList to a DataSource.
The scenario: When I add am item to the database (I do this using a GridView/ObjectDataSource / SPROC) I want to update a DropDownList that lists this items as well.This DropDownList is linked with another ObjectDataSource. Now, I listen to the RowCommand event of the GridView and in a certain case I refresh the DataSource of the DrpoDownList and do a DataBind to the DropDownList afterwards.
The strange thing is, that when I take a look at the DropDownList's Items-Collection during the Page's OnPreRender event handling, the items collection contains the new entry but the new entry is not rendered, i.e. when I take a look at the rendered HTML the <option></option> entry for the new value is missing.
After another postback to the page the entry appears in the DropDownList?

Forms Data Controls :: How To Use A DropDownList With A DataSource Returning A Datatable
Jun 10, 2010I am trying to use a datasource with a dropdownlist. Eventually, my data source method to call a stored procedure and load the datatable is returns, but for now, I am just creating the datatable manually. I need each item to have two attributes, the text, whixh the user will see in the DDL, and the value that the program will retrieve from and store back to the file.
It is partly working in that the DDL has 3 items, however the text for each item reads "System.Data.DataRowView"
I have to be close, but I can't figure out what I am doing wrong.

DataSource Controls :: LINQ Load Collection To Populate Dropdownlist?
Apr 5, 2010I have a partial class extending my Entity Model. I'd like to write a method that returns a collection of types from my entity framework model.

I tried returning a list of Objects, and a list of states to my calling method to be used to bind to a drop down list. However I get an error that:

DataSource Controls :: Filtering Between 2 Values In A Query From Dropdownlist Select?
Feb 17, 2010I have dropdownlist of dates and depending on the date that the user selects from list, I would like to filter records that fall between the startyear and finishyear columns in the datasource. (My the problem is that I do not know how to declare the Startyear and Endyear from the query in the code as they appear underlined - probably the BETWEEN syntax is wrong too).
yYear = DropDownList1.Text

cmd = "SELECT BarDetails.*, MenuHeadingId AS Expr1 FROM BarDetails WHERE (MenuHeadingId = 2)" & "WHERE " & yYear & " BETWEEN " & "(" &

Forms Data Controls :: Separate DataSource For DropDownList In DataGridView?
Sep 8, 2010I am using a DataGridView and have a master table which contains values which different tables related to the master data, i.e. StatusID =1 in master table = TrailerStatus (1, 2, 3, 4 and their descriptions) are in a related table. I am able to retrieve the values from Table B 1 = Empty, 2 = Rejected, 3 = Onsite, etc. However, I don't know how to relate the master table StatusID = 1 to default my dropdown list from the relational table 1, 2, 3, 4.
I have been fighting with this for quite some time and just have not found a solid example of how to do this. I actually have two dropdownlists which will need to be correctly wired in order for my application to work.
This will also be an editable dataGridView but I will tackle that challenge once I get this first hair plucked from my butt.
There is some code-behind which doesn't work at all pertaining to a ;; gvSCACDetail_RowDataBound ;;
but I dont' think I can even get the code to compoile when this is not commented out.
Here are some of the details:
<td style="width: 700px; height: 20px">
<asp:GridView ID="gvSCACDetail" runat="server" AutoGenerateColumns="False" AutoGenerateEditButton="True" DataKeyNames="trailerid,locationid,scacid,statusid,capacityid" AutoGenerateDeleteButton="True" DataSourceID="SCACDetailView" Visible="False" Width="698px">
