Forms Data Controls :: How To Get Item Databound Value In A FormView

Apr 27, 2010

i already have a DataList, and i get any information from the rows i need by adding code such as:


Well what i am doing there is using the values from the items that the DataList has obtained from the rows, now, what i need to do is EXACTLY the same, but for the FormView, i realised that this code does not work for the FormView, but only DataList control.

give me the code for doing exactly as shown, but for the FormView control.

Forms Data Controls :: DataBinding And DataBound FormView's Events?

Dec 27, 2010

I have a very simple form that contains a FormView Control Bound with a SqlDataSource, The DefaultMode of the FormView control is "Insert". I noticed that when I run the page for the first time, the databinsing and databound events of the FormView Control occurs after the PreRender Event of the page ! I know very well the life cycle of a page, but I dont know when the data binding occurs in the life cycle of a page and if it can differ from a control to another.

Is there an article or a tutorial explaining all those things.

Forms Data Controls :: Databound DDL Inside Formview When SelectedValue No Longer Exists?

Aug 31, 2010

I have a page that has a formview on it. Client info, name, address, usual stuff. The formview is populated by a DataSource, that calls a SQL stored procedure for the client info. It all works great.Within the formview, I have a dropdownlist for the Staff assigned to the client (StaffId is a member of the Client record called during the Formview binding). When the formview is in Item mode, the Staff name appears in a label, when in Edit mode, the dropdownlist
is bound and populated by another DataSource that calls a stored procedure of ActiveStaff. When the assigned staff exists, the StaffId is correctly bound to the DDL SelectedValue and the current staff name appears selected in the DDL when in edit mode, as it should.

Forms Data Controls :: Item Databound Event Thowing Security In Medum Trust Webserver?

Jun 28, 2010

last year I inherited a webapplication that seems to refuse to run on a new hosting company's servers due to a "security violation"... Our old host was bought out and now sucks...So I uploaded the code to the new company - looking forward to some sleep and found that my life was about to get more complex.. I go the good old generic security error

System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object

The biggest issue was that it didn't say where the error was.. Digging deeper (taking the code appart one block a time) the error was being triggered by the followin itemdatabound event. My host says it is because they are running under medium trust, but I am not seeing why this block should cause issues. Any help very much appreciated.

Sub dlstAlsoDish_ItemDataBound(ByVal s
ByVal e
As DataListItemEventArgs)
Handles dlstAlsoDish.ItemDataBound
If e.Item.ItemType = ListItemType.Item
Or e.Item.ItemType = ListItemType.AlternatingItem

Web Forms :: Formview Same Id For Controls Allowed Only If Databound?

Apr 5, 2010

I've got a formview with controls in different template views and I have a query just out of curiosity.

In my edit template I've got for example:

<asp:TextBox ID="IsPrestigeTextBox" runat="server" Text='<%# Bind("IsPrestige") %>' />
<asp:CheckBox ID="IsPrestigeChkbx" runat="server" />

and then the same code exactly in my insert template:

<asp:TextBox ID="IsPrestigeTextBox" runat="server" Text='<%# Bind("IsPrestige") %>' />
<asp:CheckBox ID="IsPrestigeChkbx" runat="server" />

However, the databound items seem to be allowed to have the same ID whereas the non-databound checkboxes arent.

What's going on there?

Forms Data Controls :: Control Parameter EVAL From A Formview Item

Aug 31, 2010

I have a Formview ('formview1') with a pager. I also have a gridview ('gridview1') linked to a SQL datasource ('History'). I need to set the SelectParameter ('Serial') of the datasource to be the value of a field on the current page in the formview. The value i need to get is in the ItemTemplate and is a label called 'SerialNumberLabel'. So, something like:

<asp:ControlParameter Text = "Eval fromview1.currentpage.itemtemplate.SerialNumberLabel" >

I also need to ensure that the SQL source and gridview rebind when the pager is activated.

Forms Data Controls :: How To Populate A Formview When Select An Item From The Dropdownlist?

Jun 12, 2010

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview.

I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:

Forms Data Controls :: Can't Seem To Retain Label Values In Formview Edit/ Item Mode

Mar 15, 2010

In web config file I have add key values specified.

In the formview I have labels on edit , item and insert mode that I want to display all the time by getting those values from web config. I'm able to do that with no problem but when I change the modes between edit to insert or item view, I lose those label values until I hit the "select" twice from the Gridview, those values re-appear. Below is the snippet of the code. What do I need to do to retain the category values all the time?

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.

I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.

Populating A Listbox From SQL Server In Databound Formview

Oct 24, 2010

I am "trying" to switch my form from SqlDataSources to ADO.NET data sources. So I have a DAL setup, and ObjectDataSources in my form referencing these DALs. These data sources are bound to the form's objects. So far so good. In the InsertItem Template of one of the form's FormViews I have a list box that I am trying to populate with a value pair (ID, TechName) from a database table and I get the following error:
"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." Apparently, one of the two workarounds involves programmatically loading the listbox. The code below shows one of my attempts, resulting in the above mentioned error:

Protected Sub TestFillDefaultValueInFormView()
Dim vInspectorList As DropDownList
If (FormViewHydInspection.CurrentMode = FormViewMode.Insert) And Not IsPostBack Then
vInspectorList = DirectCast(FormViewHydInspection.FindControl("DDlstInspBy"), DropDownList)
Dim vInspectorDA As New DataSetHydrantsTableAdapters.TechnicianTableAdapter()
Dim vInspectors As DataSetHydrants.TechnicianDataTable = vInspectorDA.GetTechnician()
Dim vInspRow As DataSetHydrants.TechnicianRow
Dim vInspectorHT As New Hashtable
vInspectorHT.Add("0", "Select Technician")
For Each vInspRow In vInspectors
If vInspRow.TechID <> 0 Then
vInspectorHT.Add(vInspRow.TechID.ToString, vInspRow.TechName)
End If
vInspectorList.DataSource = vInspectorHT
vInspectorList.DataTextField = "value"
vInspectorList.DataValueField = "key"
End If
End Sub

I tried populating the listbox directly using the Listbox.Items.add() method (which is the way I have it now so I could continue solving other problems, and it works!) but I could not find a way to add a value pair. I did try:

vInspectorList.DataTextField = "Select Technician"
vInspectorList.DataValueField = "0"
but that left a listbox without any data.
