Forms Data Controls :: Gridview With Checkbox Update One Time In A Button Click Not Every Time?

Mar 11, 2010

I have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.

Call A Web Service At Regular Intervals

Oct 30, 2011

I have a web service that calls a stored procedure to retrieve a list of users and email addresses from a database and sends reminder emails to them.

I need to set it up so this web service runs once a day automatically. My first thoughts are a 'windows service' but I've never built one before. I've looked at the documentation and thought 'sounds like a thousand things could go wrong there' if, like me, you know very little about Windows.

Forms Data Controls :: Update Datalist Automatically - Using Update Panel?

Nov 27, 2010

I am using 3.5 c#. I am trying to do this:

In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.

I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!

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.

Forms Data Controls :: Get A ListView To Automatically Update Itself?

Sep 6, 2010

I have a web page into which a user control is loaded. This user control contains a ListView. In the Page_Load event handler of the user control I have this code:

listView1.DataSource = TaskList; // Note: "TaskList" is a data table

It should be noted that the TaskList data table is actually instantiated in the web page. The user control then obtains a reference to it.

Everything described to this point works fine. Where I'm running into trouble is when I add a new row to TaskList. I had *thought* that the ListView control was dynamically connected to the data table, such that when I altered the contents of the data table in any way, that the changes would be automatically reflected in the ListView.

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.

Forms Data Controls :: Automatically Tab To Next Textbox In Gridview?

Sep 9, 2010

I have a gridview which contains textboxes. The user uses a barcode scanner which scans barcodes into the textboxes.

What I would like is to move to the next textbox after an item has been scanned in i.e. automatic tabbing to the next textbox.

Does anyone have any advise how I can do this?

What I have noticed is that when the user scans an item, the page does a full page postback even though the grid is in an update panel. And after the postback, the focus on the textbox just scanned in has been lost.

Web Forms :: Automatically Update Data Source According To Another Field?

Jul 28, 2010

There is a field called school which is a dropdown menu, I manually edit items and made it like these: select school, name of 6 elementaries and 2 middle schools, and a high school.I have another field called grade level, which is a drop down menu too, i manually entered the grade items for it: select grade, Kindergarten, 1, 2, 3......12.

I would like after user selects a school in the drop down menu, the field called grade level dropdown box' data source will be updated according to school. For example, if it is a middle school selected, the data source of grade level will be updated to 6, 7 8 grade, if it is elementary the grade will be updated to 1, 2, 3, 4 5 etc. In this way later, when user goes to select grade it will show appropriate grade level lists according to schools.
