Forms Data Controls :: Unable To Bind One Field By Using The EditTemplate From FormView Control
Aug 12, 2010
I've seen this before, I fixed long time ago and now cannot remember how I did :) My store procedure won't update the record because the sql field 'itemId' is being passed as ZERO always.
<EditItemTemplate>
<table border="0" width="100%">
<tr>
[Code]....
<td class="cxml_item_name">Active:</td>
<td class="cxml_item_value"><asp:CheckBox ID="ActiveCheckBox" runat="server" Checked='<%# Bind("Active") %>' /></td>
<td class="cxml_item_name">Created:</td>
<td class="cxml_item_value"><asp:TextBox ID="CreatedTextBox" runat="server" Text='<%# Eval("Created") %>' Width="250" ReadOnly="True"/></td>

In almost all cases, my edit template and insert template in the formview are the same.
So instead of copying pasting the same markup, i decided to put it in a user control. The display works fine, however, the databinding doesn't work anymore. It works fine if I put the markup directly in to the formview template.

I can insert a checkboxlist selected value as comma delimited string into the database. But I have hard time to reload it in formview edit mode. I added a hidden label to retrieve the comma delimited string and try to use checkboxlist databound event, but it doesn't work. I don't know what problem is in my code.

I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:

The EditItemTemplate does not even load when I click the edit button on my FormView control, but I don't get an error message either.

I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.

I have created a formview with 4 dynamic controls fields that LINQ to a database.
rentfoodutilitytotal
There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field
tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit")
tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit")
'extract string from those textboxes
txtSubtotal = tboxSubtotal.Text
txtModifier = tboxModifier.Text
'convert text to double and add them together
Double.TryParse(txtModifier, dblModifier)
Double.TryParse(txtSubtotal, dblSubtotal)
dblSubtotal = dblSubtotal + dblModifier
'post the changes back to SubTotalTextBoxEdit
'totalTextBoxEdit
'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal)
'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.

d2 is using codebehind code to load the item based on the selected value in the d1 : Not working
How to findthe control in the edit template to display item value for d2.

I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.

Does anyone have an example of a formview and a gridview master detail relationship in c# ?
The gridview datasource is a datatable and the gridview is inside of the edititemtemplate of the formview.
In what event of the formview do you bind the gridview datasource?

I need to set the value of TextBox in a FormView when the mode changes to Insert. But when I was trying to get it to work, neither one of the code blocks below worked. The value was not set, despite the TextBox being found. Furthermore, the 'test' label text wasn't being set. I know for certain that both events are firing. I had added the test label to disploay the mode or newmode of the FormView but the label wasn't being set at all.

I now can reference a field in the formview, but, assigning it a value is fighting me.
I want to assign the UserName field in the formview with the login name from the Master (HttpContext.Current.User.Identity.Name).
(A) I tried the likes of: FormView1.FindControl("UserName").DefaultValue = username but of course that doesn't work.
(B) Alternatively, I tried to edit the SQL so that I passed it the HttpContext.Current.User.Identity.Name but didn't have any luck.
InsertCommand="INSERT INTO [TechUserName] ([CertName], [CertLevel], [CertLast], [CertFreq], [CertDue]) VALUES (@temp1, @CertLevel, @CertLast, @CertFreq, @CertDue)"
temp1.text=(HttpContext.Current.User.Identity.Name)

i have a formview1 in edit mode within a modal pop up extender and Update Panel
The update statement works but on the page is a gridview1 where I want
to display the new values.
I have added the below in page code but it still does not bind
the Gridview with new values when after I click UpdateButton in Formview - Only when I refresh the page.
protected void FormView2_ItemUpdated(object sender, FormViewUpdatedEventArgs e)
{
GridView3.DataBind();
ObjectDataSource50.DataBind();

I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView
ID="fvTicketUpdate"
runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.

I have an email contact form that I have successfully populated the account users Username and email address into text boxes
I also use a text box and session variables to send parameters to a stored procedure and return a single row result in a form view.
The thing I am having an incredibly hard time figuring out is how to populate a single textbox with the data from any of those fields. or the whole control as a single summary.
Just for starters I am actually an IT Manager and NOT a coder so this is entirely a hack job if there ever was one...
here is my aspx code
<%@ Page Language="C#" AutoEventWireup="true" MasterPageFile="~/RMSWeb.master" CodeFile="Service2.aspx.cs" Inherits="_Default" %>

i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)

I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.
