Forms Data Controls :: Sharing FormView Edit And Insert Templates?

Mar 26, 2010

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;
}

Forms Data Controls :: Validating Page With Listview Edit Item And Insert Item Templates Are Both Present

Aug 9, 2010

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?

Forms Data Controls :: Change Binding Based On Formview Insert Or Edit?

Apr 24, 2010

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?

Validating Controls In ListView Insert / Edit Templates?

Oct 29, 2010

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?

Forms Data Controls :: Formview Insert Template Fill Like Edit Item Template For All Fields

Mar 3, 2010

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.

Forms Data Controls :: Editing The Default Templates In ListView And Formview?

Feb 18, 2010

This 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.

Forms Data Controls :: Formview Force Table Width In Templates?

Mar 29, 2010

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%;">

Web Forms :: Changing FormView From Insert To Edit?

Mar 22, 2010

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.

Forms Data Controls :: Formview From Readonly To Edit Mode

Jan 14, 2011

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?

Using User Controls In FormView Templates?

Apr 24, 2010

I 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?

Forms Data Controls :: Accessing Inside Formview Edit Template

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.
