Forms Data Controls :: Asp 3.5 Time Field In FormView / Update/insert Time Fields?

Oct 20, 2010

This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.

Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)

If IsDate(pasDate) Then
If pasDate <= System.DateTime.MinValue Then
Return Nothing
Return CType(pasDate, DateTime)
End If
Catch ex As NullReferenceException
Return Nothing
End Try
Return Nothing
End If
End Function

So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".

I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.

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?

Forms Data Controls :: Formview Update Crashes If ID Fields Are Empty?

Apr 8, 2010

I have a Formview control that has several lookup fields. The value is an int ID but the textfield is the name, e.g. value = StateID, displayed text = StateCode)

If the user leaves that field blank, I get a Server Error when attempting to Update: Failed to set one or more properties on type orgOrganization. is not a valid value for Int32.

In the table for the LinqDataSource which provides the data for the Formview, all fields except the text field OrganizationName allow Nulls.

Does anyone know why this might be happening? I tried a test which just has the numbers, no lookups, and get the same result.

Forms Data Controls :: Time Used As "amount Of Time Available", Not Time On A Clock?

Jul 6, 2010

how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.

Forms Data Controls :: Retain Formview After Insert Or Update?

Jan 18, 2011

I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.

AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?

Forms Data Controls :: How To Update A Dynamic Control Field In A Formview

Jun 28, 2010

I have created a formview with 4 dynamic controls fields that LINQ to a database.


There's an event handle for each of the first three fields whenever a text change with following codes:

' extract textbox from both SubTotal and the modified field
tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit")
tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit")
'extract string from those textboxes
txtSubtotal = tboxSubtotal.Text
txtModifier = tboxModifier.Text
'convert text to double and add them together
Double.TryParse(txtModifier, dblModifier)
Double.TryParse(txtSubtotal, dblSubtotal)
dblSubtotal = dblSubtotal + dblModifier
'post the changes back to SubTotalTextBoxEdit
'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal)
'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)

I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.

Forms Data Controls :: Using A Formview To Update A Database With A Insert Button

Jan 5, 2011

I am *VERY* new to This may seem simple to you all, but I'm really lost. I have a small sized page with three text boxes (part of the InsertItemTemplate) of a formview, and a slightly modified link the system generated to submit the data to be inserted in the database:


If this page is run, it inserts the data into the database fine, clears the form and sits there. I want it to return a simple "Thank you" page in a window of the same size, with a Close Window buttom at the bottom to close the window:


When I set the postbackurl property on the first page, everything appears to work, except the write is never done to the database. If I remove the postback, it works as it did previously.

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 :: Formview Insert Adds All Null Values - Update Doesn't Update Values

Apr 12, 2010

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
