Is there a way to create only the InsertItemTemplate in the FormView and then assign it to EditItemTemplate. Something like
Page_Load
{
FormView.EditItemTemplate = FormView.InsertItemTemplate;
}
I am using a formview on main web page and the Item template displays my data correctly but I get and error when I try and link to the edit or insert templates.This happens on our remote tesing server only.On my local machine running the page on the local server in VS 2010 everything works fine.But then doesn't it always work on your local machine.I might also mention that I am compiling for asp.net 4.0.
Here is the stack trace :
System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'MYCORPABIGWEB01$'. at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()

I would like to change the layout of the edit and insert templates to show multiple columns (instead of the default 1), and make the required fields show in the first column. Please point me in the direction I need to go.
View 1 Repliesi am using two tables for salary components like bonus,hra,ta,da.one is salary lookup table for viewing which components are chosen and according to this salary table is created dynamically.i want to view data fields of salary table in gridview and update thier value.
now problem is that how to create template field and edit template field for updating fields of salary table because field of the salary table changing every time as it is creating dynamically.
I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
I'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?
I added a RequiredFieldValidator to my InsertItemTemplate, and it seems to be working fine. The problem I am having, however, is that now I cannot do anything else in the ListView (like edit or delete items) UNLESS the required field has a value. Is there some way I can manually do the validation when the user clicks the 'Insert' button on the InsertItemTemplate, or some other little trick I can perform so the user doesn't have to first type in a value just to delete something else in the list?
View 1 RepliesI 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.
View 8 RepliesI need to create and use asp.net FormView with pager, dynamically from code behind in C#.
View 2 RepliesThis is probably a dumb question, but I have to ask because I spend so much time editing my formviews and listviews. Is there a way to edit the default template setup for these controls, in the code or somewhere? When you drag them over you get the default text with textbox column names; then I spend over 30 mins editing each to look the way I want it to.
I know I can create standard templates for WebForms and save them as Exported Templates.
And is it possible to edit the default control when you drag them on to the page, to list certain attributes automatically. example (validation controls you always have to add ControltoValidate I would like to drag mine onto the page and it say controltovalidate="" and then all I do is fill in the blank. Intellisense is fine, but sometimes you get brain freeze after hours of web design and forget the needed attribute and you have all to go through all of the errors and mistakes.
The ultimate would be, to drag a FormView Control and when you Refresh the Schema, you get textboxes, label controls instead of text for column name, and divs for forms, and Image Buttons , I am sure there is an XML file that runs the code that you can edit or something.
OR
ASP Developers, When you develop the next ServicePack allow us to edit or create default templates to customize the default templates, in VS and VWD.
to force a table width in Formview control templates? I have created a table in the ItemTemplate that works fine but I can't seem to get the table to fill the entire width of the display area. I tried wrapping the entire FormView
in a div tag and setting the width to 98% but it didn't work either. Aplogies in advance if this has already been asked. I found a lot of references to GirdView (which didn't help) and nothing helpful r/e FormView except the div tag suggestion.
Here is the code I am using for the ItemTemplate (VS 2008, VB [preferred], in a master page):
Sample ItemTemplate
<ItemTemplate>
<table cellspacing="0" style="width:98%;">
<tr>
[code]...
After I use FormView in InsertMode and the record is added, I want it to switch directly to EditMode.
I assume I would place this command in this action:
protected
void FormView1_ItemInserted(object sender,
FormViewInsertedEventArgs e)
However, I can't find the correct command to issue.
my EditItemTemplate is not appear in my page, when i load my page it's does'nt exist but I already change my DefaultMode to Edit
View 1 RepliesI use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?
View 3 RepliesI 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.
This is what i have using VS and VB: formview that is bound to a sqldatasource. In the formview i set up three panels and the visibilty is controlled by three buttons. I want to be able to click the edit link button and have the panel that is visible in readonly mode be the one visible in editmode
View 6 RepliesThere is a dropdown with two status (Cleared, Pending) in the formview.
I want to hide Edit button of the form if the dropdown displays Cleared. So that the user may not edit further in the data.
I'm trying execute code only when FormView is in Edit mode ---but the code following line this is being executed even in read-only mode.
If formname.CurrentMode
= FormViewMode.Edit
Then
there are 2 pages (SummaryGridviewPage.aspx and FormviewPage.aspx) there are insert, item and update templates in the FormviewPage 1st case - there is no problem to insert new record, select and update action in the FormviewPage
2nd case - However, there is problem when i select a record in GV and direct to FormviewPage for edit this code is added in Formviewpage to open the record at readonly mode, no problem
Private Sub RF_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Session("RecordID") <> "" Then ' to check New or Old record
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.ChangeMode(FormViewMode.ReadOnly)
End If
End Sub
however, no record if go further from readonly to edit mode then Code is added to the Edit button
Protected Sub BtnEdit_Click(ByVal sender As Object, ByVal e As EventArgs)
FormViewProject.ChangeMode(FormViewMode.Edit)
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.DataBind()
End Sub
Now edit problem is solved but when go back to the 1st case (new record, and then edit) Now new record can be inserted, and then show it in readonly mode. but then try to go to edit mode, no record show i think BtnEdit_Click code is conflicted with the built-in "Edit" command Could anyone show me some info how formview retrieve specific record in a proper way?
Is it possible to update and edit a record in Formview at the same time. Currently, the formview's default mode is set to Insert where users can add a new record to an SQL database, however, when that record is added I need that information to update another table all on one click. Is this possible with a stored procedure or a button that allows both?
View 4 RepliesI find the repetition of sets of controls for each of the EditItemTemplate, InsertItemTemplate, and ItemTemplate templates of a FormView to be tedious and risky, in terms duplicating layout and code etc. I would much rather create a xxxDetails user control, and use this in each template, cutting layout and code location down to one location.
However, this introduces several complexities for data binding scenarios. Are there any extablished patterns or practice guides for using user controls in these scenarios?
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.
