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:
void FormView1_ItemInserted(object sender,
FormViewInsertedEventArgs e)

However, I can't find the correct command to issue.

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.


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?

DetailsView Changing Field Display For Edit Versus Insert Mode?

Jul 18, 2010

For ASP.NET, I'm using a DetailsView for insert and edit of a record. For edit mode I don't want to display the primary key field because it should not be changed. For insert mode, I want to display the primary key field because it doesn't exist and the user can specify it via a DropDownList that insures they will pick an unique value. A TemplateField is used in the DetailsView markup for the primary key field (hence the DropDownList for insert mode).

My problem is that I cannot get the primary key field to not display for edit mode and to display for insert mode. In the markup I have:

<asp:TemplateField HeaderText="name" InsertVisible="True" Visible="True">
<asp:DropDownList ID="ddl2NonMembers" runat="server"
SelectedValue='<%# Bind("member_grp") %>'>

With the TemplateField Visible="True", the HeaderText="name" always displays which I don't want for edit mode. With the TemplateField Visible="False", the field never displays which I don't want for insert mode.How can I achieve the display behavior I want for insert verses edit mode. I'm fine with changing some property programmatically rather than relying an a pure markup approach,

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 :: Changing FormView Mode Using VB.net?

May 30, 2010

I have created a FormView whose defaultmode = "insert". When loaded the FormView displays the InsertItemTemplate. At the top of the page is a DropDownList used to select Clients. I have added a list Item to the DropDownList with value = "0" and text= "Select Client" option. So the Page is in Insert Mode. SO FAR EVERYTHING IS AS EXPECTED.

When I select a Client from the DropDownList, the page remains in Insert Mode (Don't understand why? ) Could it be the default Mode setting? So I added the following vb code.

Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged

If ddlSelectClient.Text <> "(Select Client)" Then
If FormView1.CurrentMode = FormViewMode.Insert Then
End If
End If
End Sub

So after an existing Client is selected, the FormView Mode should be changed to EDIT. AND INDEED THE EDIT ITEM TEMPLATE IS DISPLAYED.

Ah but life is not so simple (after all this is a Microsoft Application). So I enter data in some fields and click the [Update] Button.

Then I get the following message:

FormView 'FormView1' must be in edit mode to update a record.

THe FormView displays the Edit Template, the Update and Cancel Buttons are displayed. All this should mean I am in edit mode.

Just call me FrankenSoft !@#$%^^& or is it MicroStein?

Oh by the way I'm using Linq to SQL data sourcess. Should I be? I'm having a lot of problems with the FormView using Linq.

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")
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)
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
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?
