Forms Data Controls :: DropDownList Inside FormView Insert Template
Sep 13, 2010
I am trying to change the textboxes in the FormView insert template to dropdownlists but they keep setting the parameters to null. Here's what I have:
[Code]....
In Page_Load
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2010", "2010"))
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2009", "2009"))
and in the SqlDataSource
InsertCommand="INSERT INTO [tblSurvey] (... [YearOfQualification] ...) VALUES ( ... @YearOfQualification ... )
And in insert parameters:
<asp:Parameter Name="YearOfQualification" Type="Int16" />
And the insert fails with YearOfQualification as null. If I sue the standard textbox:
<asp:TextBox ID="YearOfQualificationTextBox" runat="server"
Text='<%# Bind("YearOfQualification") %>' />

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

I keep getting a null reference when I try to access a listbox inside the EditItemTemplate of a formview. I check the mode before accessing the control (Formview1.CurrentMode) to make sure it is in edit mode and even set it manually to edit mode again! But formview1.findcontrol("blah") returns null. Formview1.EditItemTemplate does not have a FindControl method, not sure what else to try.

In my listview object insert/edit template, I have two dropdownlists (category, subcategory). When a user selects a category (autopostback), I would like the subcategory dropdown to filter to only the those that match the categoryID from the category ddl. This seems to be complicated by the fact that it is in a listview object. I'm currently using a queryextender on the subcategory datasource, but I'm not sure how to apply the selectedvalue of the category to the queryextender. The subcategory just shows all items and is not filtered. How do you accomplish this?

I am using a formview to show data, with edit, insert and delete enabled. My problem is with the insert.When i click the insert, the formview changes fine to the template for inserting new data, the problem is it was allowing the user to insert the ID themselves, I have made this readonly, but how would i go about ensuring the ID key is made the next number in line? and that it is printed to this textbox?

I created a formview that I am using for data input (DefaultMode=Insert)
One of the objects I have is a text box (see below)
[code]....
When I click submit I get a message that I cannot insert a Null into the field IntershipNumAvailable. This makes sense since I made this field a required field in the database.
How do I get the form to recognize that the user selected item is the one I want to write to the database?
What changes do I need to make here? Do I need to make changes to my parameter list?

I have a formview on a web page, set to insert mode as default. The form view is bound to a SQLDatasource. This datasource has a custom query written to select the details for this formview. The query joins two tables to provide relevant detail and not just an ID for one of the elements on the form view.
The first tabe contains information regarding projects and the second table contains detail regarding Resources. First table has the following definition:

I have a listbox inside a formview in a details page(master/details). The values for the listbox will come from a lookup table and when the user select one or more values it should be inserted in a table. The process sould be like the following:
The user will select one or multiple values and click on a Select button. Then a label should show the selected values. Then the user will click on the Insert button in the formview to insert it in the database.

I have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?

I am using C#, Object Data Source, formview and a BLL. I have two drop down lists and two data sources. One populates the other. Drop down list #1 populates Drop Down list # 2 based on its selection . Drop down list # 1 is populated with DataSource #1. Forview is using DataSource #3 to send the ietms. When I add: SelectedValue='<%#Bind("Make_ID") %>', I get the error below:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control
I have seen a solution online but it is using LINQ and I am not familiar with it. I need to find the selected value of the drop down lists.

I've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table....

I would like to set the one template for edit/insert and view in my custom FormView control . But i got these odd exception Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.Table'.
public class CustomFormView : FormView
{
[PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(typeof(FormView), BindingDirection.TwoWay)]
public IBindableTemplate FormTemplate { get; set; }
protected override void OnInit(EventArgs e)
{
ChangeMode(FormViewMode.Edit);
if (FormTemplate != null)
{
if (CurrentMode == FormViewMode.Edit)
{
FormTemplate.InstantiateIn(this);
}
}
base.OnInit(e);
}
}
edited :
in the first step , I created the new user control and added a formview ("FV")
public partial class Form : UserControl
{
private IBindableTemplate _template = null;
[PersistenceMode(PersistenceMode.InnerProperty),
TemplateContainer(typeof(FormView), System.ComponentModel.BindingDirection.TwoWay)]
public IBindableTemplate FormTemplate { set;get }
protected void Page_Init()
{
if (FormTemplate != null)
{
FV.InsertItemTemplate = FV.EditItemTemplate = FormTemplate;
if (!IsPostBack) FormTemplate.InstantiateIn(FV);
}
}
}
Now , I want to convert this user control to web control.

I have a simple EditItem Template within a Formview that I am using to add a record to a table. There is one field in the form that I would like to assign a variable to. I cannot figure it out. I do not see any properties in VS2008 that allow me to assign the value.
The value that I am assigning is an item number, wich is the primary key in the table that I supply on the form.
