Forms Data Controls :: Strange SqlDataSource Behaviour Updating GridView On Server Vs Development Machine?
Jun 10, 2010I'm having a strange problem - probably has a simple answer but, I haven't been able to find it or figure out the cause. I'm hoping someone has had this same problem and figured it out.
Basically - my application works great on the development machine. So I copy it over to the server and it works great. Come back the next day and my GridView is only displaying the first record...I then log into the server remotely and open the web page on the server and all records are returned, so the application works fine on the server. I then return to the local machine and now the application is returning all rows in the GridView. So, weird but, what whatever, it works. Go away and come back again the next day and...
1 ) Only 1 record from dataset is displayed in GridView
2 ) Log onto server remotely and view webpage on server --> all records now display
3 ) Try again on local machine, now application works fine...grr. What am I doing wrong here? Using Visual Web Developer 2008 on Windows XP. Querying SQL Server 2000 (I know, I should switch to 2005 and use VWD 2010 - but ouch, really!) when a text box value changes (Vendor_PO_TextBox.TextChanged)

DataSource Controls :: Strange Behaviour With Connection Pooling
Jan 12, 2010Some one can explain me the behaviour i am observing is correct..?
[Code]....
and here is the connection string:
<add name="SecurityDB" connectionString="Data Source=xyz,8000;Initial Catalog=abcd;User ID=abcd;Password=defg" providerName="System.Data.SqlClient"></add>
i expect it to fail at 101 iteration as the default max pool size is 100 and i am not releasing any connection after i open(ie., Not closing or Disposing). But the strange behaviour is i can go up to 230 iterations and then it gives me a timeout error, can not acquire new connection.
When i look in SQL Database for number of connections created it is only 100.
My question is : When connection is not released, how is it able to re-use the previously opened connection.
AJAX :: MaskedEditValidator / Strange Behaviour?
Dec 20, 2010I am using the MaskedEditExtender and MaskedEditValidator, but have experienced some strange
behaviour. (See code example below). When entering a date into the textbox this is what I see:
1. The mask
2. Entering the date and time e.g. "19-01-1980 10:11:12"
3. When removing focus from the textbox the result is: "19-01-1980 19:01:19"
The six first digits of the date is copied as the time? If entering a day of the month larger than 23 and any given month, year and time (eg. 25-10-1980 12:12:12) the validation fails as the six first digits are copied to the time resulting in a time 25:10:19 which obviously is not valid.
I have downloaded the AJAX toolkit sample code and experience the exact same behaviour. When running the AJAX Toolkit samples from[URL] works fine!
Additinal info: Culture is danish (DateTime format is dd-MM-yyyy hh:mm:ss). Tried changing my systems culture to en-US but same behaviour.

Forms Data Controls :: Validating Page With Listview Edit Item And Insert Item Templates Are Both Present
Aug 9, 2010I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

Forms Data Controls :: ListView Does Not Insert Item?
Mar 13, 2010What I'm trying to do is: I have a listview control on my page and in my code behind, I created an SQLDataSource object which I defined its Select, Delete, Update and Insert Command strings. I then binded that datasource to my listview. When I load the page, it's obvious the select command works. however, when I perform the insert, the ItemInserted event triggers, but the itemInserted doesn't trigger and there is nothing inserted in my database.I'm not sure what to do here. I also hard coded the insert values in my insert command. So it's not depending on the form values.

Forms Data Controls :: Scrolling One Item At A Time With The ListView?
Apr 30, 2010Suppose I have a horizontally oriented ListView that always shows 4 items and also has a left & a right button: < A B C D >
Now, let's say I have a DataTable containing 20 entries, with indices ranging from 0 to 19.
When the page first loads, this is what'll be displayed: < 0 1 2 3 >
Assuming those buttons are regularly configured DataPage buttons then if I press the right one we'll get this: < 4 5 6 7 >
And if I press the right one again we'll get this: < 8 9 10 11 >
But suppose I'd like the left & right buttons to only scroll one at a time, so that pressing the right one at the start results in this: < 1 2 3 4 >
In such a case, is there a way to configure the DataPager to do this or should I instead introduce regular buttons and perhaps have them call a hidden DataPager?
