Forms Data Controls :: DropDownList In DetailsView Without SQLDataSource?

Nov 2, 2010

I am trying to use a DropDownList in a DetailsView for the ItemTemplate, InsertItemTemplate, and EditItemTemplate. I must bind this DropDownList to a SQL-Server support table using a function that returns a DataTable. I am not allowed to use a SQLDataSource in my backwards IT department. So, not only do I need to load the DropDownList, I also need to make the SelectedValue equal to the current record that I am viewing, editing.

Forms Data Controls :: How To Move A Detailsview Sqldatasource To Codebehind

Apr 5, 2010

I have working code similar to the following in my Detailsview:

<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:DATABASE %>"
SelectCommand="SELECT Id, PracticeId, FirstName, LastName, Notes FROM Providers WHERE Id=@Id"
UpdateCommand="UPDATE Providers SET
PracticeId = @PracticeId,
FirstName = @FirstName,
LastName = @LastName,
Notes = @Notes
WHERE Id = @Id"
InsertCommand="INSERT INTO Providers (
PracticeId, FirstName, LastName, Notes
@PracticeId, @FirstName, @LastName, @Notes)">
<asp:QueryStringParameter Name="Id" QueryStringField="Id" Type="String" />
<asp:Parameter Name="Id" Type="Int32" />
<asp:Parameter Name="PracticeId" Type="Int32" />
<asp:Parameter Name="FirstName" Type="String" />
<asp:Parameter Name="LastName" Type="String" />
<asp:Parameter Name="Notes" Type="String" />
<asp:Parameter Name="Id" Type="Int32" />

I would like to move all of this to codebehind so it's easier to work with programmatically. For instance the PracticeId is a selection from a dropdownlist that is populated from another table... i need to determine what the current selection is first so i can display the record / bind properly.

Forms Data Controls :: Using AND / OR Parameter From A DropDownList In A SqlDataSource

Jan 29, 2010

I am facing a small issue in using a DropDownList that has only two values (AND and OR) which i want to use to configure a SQL Query in a SqlDataSource. How can i use this thing by passing the value in a SqlDataSource Select Query in such a way to Bind the Result to a GridView. I want something like this -

SELECT [somefields] FROM instinvoice WHERE Namen = @Namen @Option InvoiceNo = @invoiceno where @Namen is from a DropDownList and InvoiceNo is from a TextBox

I m having a problem in specifying this @Option parameter from a DropDownList which contains only two list items - AND and OR. On the Basis of the Selected Value from this DropDownList i want to execute query like

SELECT [somefields] FROM instinvoice WHERE Namen = @Namen AND InvoiceNo = @invoiceno


SELECT [somefields] FROM instinvoice WHERE Namen = @Namen OR InvoiceNo = @invoiceno

Using the Query with @Option gives me a Parsing Error. Why is that so. How can I implement this scenario.

Forms Data Controls :: How To Put Tooltip In Dropdownlist Bind With Sqldatasource

Mar 4, 2010

I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,

item.Attributes.Add("title", someotherdatabasefield);

The end result would be something like this where the text for 'title' comes from the database

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />

Forms Data Controls :: Can't Insert From A Dropdownlist Within A Detailsview?

Oct 18, 2010

I figure that this should be relatively straightforward, but I still can't get it to work. I have a gridview and a detailsview to set up shifts for students and teachers. I would like to be able to insert new shifts using a detailsview. I will limit the students, teachers and location to items that are in a dropdownlist. The problem is that when I handle the iteminserting event. the e.values collection doesn't contain all of the fields I want to populate. How do I add the new fields to the list. This is my codebehind:

Forms Data Controls :: Cannot Insert Value Of Bound Dropdownlist In Detailsview

Apr 25, 2010

I have a dropdownlist in the edititemtemplate of a detailsview. The dropdownlist is bound with an objectdatasource. The detailsview is bound to a seperate objectdatasource which connects it to the insert method. When the page loads the dropdownlist is bound properly. However, when I make a selection and select insert I get the following error: Could not find a property named 'DeptID' on the type specified by the DataObjectTypeName property in ObjectDataSource 'objCurrentProduct'. I've tried to remove the SelectedValue='<%# Bind("DeptID") %> attribute. I can then insert without an exception being thrown but the selected value of the dropdown is not recognized. Here is the code:

Forms Data Controls :: Error In Editing DetailsView With Dropdownlist

Feb 22, 2010

ASP.NET - C# (C Sharp) - SQL Server

I've got a master table and a child table. The master table has a nullable column called ReferenceID and in some cases it should be NULL, but when it's null in a record, I get an error while going to Edit mode of DetailsView.

DB Tables:
MasterTable [Columns: MasterTableID (PK), Name, ReferenceID (FK)(Nullable)]
ReferenceTable [Columns: ReferenceID (PK), Reference]
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False">
<asp:BoundField DataField="MasterTableID" HeaderText="MasterTableID"/>
<asp:BoundField DataField="Name" HeaderText="Name"/>
<asp:TemplateField HeaderText="Reference" SortExpression="Reference">
<asp:DropDownList ID="DropDownList_Reference" runat="server"
DataSourceID="ObjectDataSource_ReferenceTable" DataTextField="Reference"
DataValueField="ReferenceID" SelectedValue='<%# Bind("ReferenceID") %>'>
<asp:Label ID="LabelReference" runat="server"
Text='<%# Bind("Reference") %>'></asp:Label>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
Select Queries:
Select MasterTable.*, ReferenceTable.Reference
From MasterTable INNER JOIN
ReferenceTable ON MasterTable.ReferenceID = ReferenceTable.ReferenceID
Select * from ReferenceTable

In Read Only mode all everything is OK, but when I click on Edit and Postback happens, I get the following error: Server Error in '/Sample' Application. 'DropDownList_Reference ' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value It means that in MasterTable, the ReferenceID shouldn't be NULL, but it should be in some cases.

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.

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 :: Dropdownlist Bound To Sqldatasource Adds Items Instead Of Replacing On Change?

Aug 26, 2010

I have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:


Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).

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:

Forms Data Controls :: DetailsView DropDownList Do Not Find ListItems Entries?

Mar 30, 2010

I am using Visual Studio 10/ASP4 but I am sure this problem is me. I created a program and got it all working. GridView and DetailsView, edit, insert and delete all works. :-)... I have spent 4 solid days attempting to have a simple DropDownList with three items on it EDIT a record. Lots of GOOGLeing for suggestions. It just will not work. The insert dropdown works fine(thats how I created the record). I wrote a new simplified program with just the detailsview and the edititem dropdownlist. Still can't get it to work. The detailsview data has a record and the "mode" field (char(20)) has three letters "FTP" in it. The letters display on the Detailsview. I can edit fine but when I add the following drop down list the page aborted with a

"'DropmodeEdit' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"

Yet there is only one record and it HAS "FTP" in it! The list has FTP in it? I just don't get it, why?

I added an ondatabinding routine and breakpointed it in the try/catch and found the selectedindex pointed to the correct entry and the items list had the correct entry with no spurious data or spaces. The data being passed displayed good in the detailsview, Am I correct in assuming that is bound to the dropdownlist automatically? or is there some majic that I did not get from Rob Burke?

<asp:TemplateField HeaderText="mode" SortExpression="mode" >
<asp:DropDownList DataValueField="mode" DataTextField="mode" ID="DropmodeEdit" Runat="server"
OnDataBinding="mode_OnDataBinding" AppendDataBoundItems="True"


I have used a dropdownlist once before with a datasource instead of listitems, this should be easier?

Forms Data Controls :: Unable To Bind Data To DropDownList In DetailsView

Sep 15, 2010

I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.

The scenario:

DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.

Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.

when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.

The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.

My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".

I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.


The SqlDataSource used to select the parameters from the table and populate the DetailsView


The code of the fields that hold the DDLs in the DetailsView control

Forms Data Controls :: DetailsView: DropDownList Keeps Getting Original Values (user Selection Is Ignored)

Feb 17, 2011

I have EntityDataSource for DetailsView which is in Edit mode by default (showin Update, Cancel link buttons).

This datasource also has foreign key called PecID. If I change the value in textbox bound to PecID, it works fine.
Entering IDs is not very user friendly, so I add dropdownlist and new datasource.

When I select new value from dropDownList and press update the DropDownList's selection is restored to original (previous) value.
Other values in textboxes are saved as expected.

After few hours of trying to figure out what is going on, I got lucky. I figure out that it is important the order of TextBox and DropDownList in field template.

This is the working order (textbox before DropDownList)


This one doesn't work [Code]....
