Forms Data Controls :: How To Change A Textbox To Dropdownlist In Formview Insert Mode
Jan 5, 2010
I created a formview that I am using for data input (DefaultMode=Insert)
One of the objects I have is a text box (see below)
[code]....
When I click submit I get a message that I cannot insert a Null into the field IntershipNumAvailable. This makes sense since I made this field a required field in the database.
How do I get the form to recognize that the user selected item is the one I want to write to the database?
What changes do I need to make here? Do I need to make changes to my parameter list?

So, I'm trying to use form view in insert mode on a dedicated aspx page. So when a user clicks "Add New" from the main GridView page, it will take the user to an Insert.aspx page that will be in Insert mode ready to collect information.
Here's what I have so far, and all I get is a blank page when I try to run it.

I have a FormView at the very bottom of the page in insert/edit mode. When I click insert/update button, the whole page reload and the pointer does not keep within the Formview but go to the very top of the page far away from the desired FormView.
What can I do here to prevent cursor going outside the Formview ? Is it I can use update panel ? What and where I should use the tags ? Or there are other better way ?

way to change a ListView into Insert Mode when linkbutton is not part of the ListView? Basically I have a button at the top of my page and when the user clicks the button I'd like to put the ListView into Insert Mode. I'm assuming that it's not working currently because the button is NOT part of the listview Layout Template.
<asp:LinkButton ID="lnkMachines" Text="Create New Machines" CommandName="Insert" runat="server" onclick="lnkMachines_Click" />

I am simply trying to get a querystring value and pass it to a textbox in a formview with the default view set to edit mode.
Protected Sub fv_Detach_Engine_DataBound(ByVal sender As Object, ByVal e As EventArgs) Handles fv_Detach_Engine.DataBound
If fv_Detach_Engine.CurrentMode = FormViewMode.Edit Then
Dim tbx_IDProfileAccount As TextBox = TryCast(fv_Detach_Engine.FindControl("tbx_IDProfileAccount"), TextBox)
If tbx_IDProfileAccount Is Nothing Then
tbx_IDProfileAccount.Text = Request.QueryString("IDProfileAccount")
End If
End If
End Sub

I am trying to change the textboxes in the FormView insert template to dropdownlists but they keep setting the parameters to null. Here's what I have:
[Code]....
In Page_Load
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2010", "2010"))
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2009", "2009"))
and in the SqlDataSource
InsertCommand="INSERT INTO [tblSurvey] (... [YearOfQualification] ...) VALUES ( ... @YearOfQualification ... )
And in insert parameters:
<asp:Parameter Name="YearOfQualification" Type="Int16" />
And the insert fails with YearOfQualification as null. If I sue the standard textbox:
<asp:TextBox ID="YearOfQualificationTextBox" runat="server"
Text='<%# Bind("YearOfQualification") %>' />

I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event:
Dim
dv As
TextBox =
CType(DetailsView1.FindControl("txtNew"),
TextBox)
If (e.NewMode =
DetailsViewMode.Insert)
Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
Where do I put the logic and what am I missing?

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 have a formview on a web page, set to insert mode as default. The form view is bound to a SQLDatasource. This datasource has a custom query written to select the details for this formview. The query joins two tables to provide relevant detail and not just an ID for one of the elements on the form view.
The first tabe contains information regarding projects and the second table contains detail regarding Resources. First table has the following definition:

This is my first post on this forum. I have a Gridview with the following Columns
1. Edit Column
2. User_ID (Read Only)
3. Email (Read Only)
4. Role ( A Dropdownlist with 2 list Items namely "Admin" & "QA Lead")
I have used wizard to populate a "Gridview" and the embedded "Dropdownlist" control in it. This is my reference: [URL] My Problem: The Data populates perfectly in Grid and Dropdownlist. But, when I Press "Edit" button the Dropdownlist goes into edit mode in the form of a "Texbox". (i dont want this) I still want it to be an editable dropdownlist.

I have a Formview where students put their information in such as name, address, etc. The text boxes are bound to my database, so once they are done, they choose to update, and my database is updated with their information. My problem is that the students often use All Caps to enter in their information.
I think I need the StrConv somehow, but I just can't seem to get this done. I've seen where it could be done with text boxes, but not when they were in a Formview using parameters.

When a FormView control is in insert mode, a data entry form is shown where the user will type a value into each textbox corresponding to a table column.
How do I disable data entry for one of these textboxes and instead, assign a system-calculated value to that text box?
