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

Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.

I have 3 cascading dropdownlists. Everything works OK EXCEPT whenever I change the selection in the dropdownlist, the old values from the previous selection are added to the new values (specifically DropDownList id=InstructorList and CourseNumberList)
ASPX page,
<asp:AccessDataSource id="CourseNameSource" Runat="Server" DataFile="r:angel_file_storageCourses.mdb" SelectCommand="SELECT DISTINCT CourseField FROM (SELECT Mid(CourseField, 1, 4) AS CourseField FROM Course_Load) ORDER BY CourseField"/>

I have a problem I have been googling the entire day and still have no soloution. I have a detailsview with 2 dropdownlists. Fisrt one is ddlCaregory. Second is ddlSubCategory. The value is passed from the first ddl to display the SubCategory linked to ddlCategory. Both ddlCategory and ddlSubCategory are Templatefields. This is also in VB.
The Details view has a sqlDataSource (sdsApplicants), ddlCategory has a Datasource (sdsCategory) and ddlSubCategory (sdsSubCategory). ddlCategories lists the data returned from sds Categories and save any changes to sdsApplicants. I can get ddlSubCat to display the correct SubCatagory bases on ddlcategory sesection but as soon as I try bind it to sdsApplicants I get the following error
'ddlSubCategory' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

I have two ListBox in my ascx file, I fill them with some data (no problem here), I make them multiple and increase the size, below is my code.
[Code]....
I use some jQuery code to exchange element between them (Here too, no problem). My problem begin when I post my form, I'm unable to get the data from the DropDownList with attribute multiple or size. I tried in my controler to add a FormCollection parameter, I can see every element in my form except those select tag with more options than id and name. I tested to put a manual select tag in my code with only an id and a name then add size and multiple attribute, when there is only id and name I can get the value but when there are more I can't get my select tag in the FormCollection
Also I need to get all the value in the ListBoxand not only the ones who were selected. I have been searching answer for 2 fays now... Without success, I only find resource on how to show ListBoxbut not how to get values from them in mvc web site and I don't find any resources who talk about multiple selection ListBox, I think I'm a bad searcher but....

I have a problem with binding a DropDownList. Let's assume a database five years old with many historical records. In order to enable just working with active data every datasource has a column hidden which is occasionally set by administrator in order to clean up old records. The selection looks like
1) SELECT Id, Value FROM Table WHERE Hidden = 0
The issue arises when the user opens a form with old data. As some records in DropDownListhave have already been hidden an exception is raised as the component cannot find the data for the list. For this case the following selection is valid
2) SELECT Id, Value FROM Table
it is possible to combine these two selection queries? The display value should always use query 2 while the listed values should use the query 1.

I really have a big problem(stuck) with two dropdownlists inside a detailsview.I have 4 detailsview : DdlRt,DdlRt2,ddlMobv1,ddlMobv2. Basically what happens here is that DdlRt2 gets populated when DdlRt is selected and ddlMobv2 gets populated when a specific value from ddlMobv1 is selected.
In code posted above the detailsview has a "Update" command and the problem is when the update command is executed the data is successfully posted to the db BUT! THE VALUES from DdlRt2 and ddlMobv2 dissapear! And I can't insert any more Items. The only Item that stays in these two dropdownlists is the default "Select Department" item which is't set in codebehind but is set in .aspx.....I can't figure what I'm doing wrong here It must be something with databinding & events.
So my question is "Why can't I insert any more items to these two dropdownlists after the "Update" command on the DetailsView is set or how can I preserve the values that are already in"?
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataSourceID="odsRegister"
DefaultMode="Edit" Height="50px" Width="125px" > [code]....

I'm trying to filter data based on the selected value from a drop down list and the according values of a local variable within a gridview_rowdatabound event. For example, if "In Arrears" is selected, the gridview should return all rows where the account balance is less than -100. So far, when I select a value from the dropdown list, it has no effect on the gridview. Here's the code I have:
If (DropDownList1.SelectedIndex = 0) Then
e.Row.Visible = True
ElseIf ((DropDownList1.SelectedIndex = 1)
And (AccountBalance <= -100))
Then
e.Row.Visible = False
ElseIf ((DropDownList1.SelectedIndex = 2)
And (AccountBalance > 100)
And (AccountBalance < -100))
Then
e.Row.Visible = False
End
If

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.

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:
Sub On_Inserting(ByVal sender As Object, ByVal e As DetailsViewInsertEventArgs)

I would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?

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:

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">
<Fields>
<asp:BoundField DataField="MasterTableID" HeaderText="MasterTableID"/>
<asp:BoundField DataField="Name" HeaderText="Name"/>
<asp:TemplateField HeaderText="Reference" SortExpression="Reference">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList_Reference" runat="server"
DataSourceID="ObjectDataSource_ReferenceTable" DataTextField="Reference"
DataValueField="ReferenceID" SelectedValue='<%# Bind("ReferenceID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="LabelReference" runat="server"
Text='<%# Bind("Reference") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
</Fields>
</asp:DetailsView>
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.

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.
