Thanks for the reply.
I'll try you solution. It looks somewhat better than the the solution I came up with my self. I try to dig in to the UserControl to get the value like this;
Label1.Text = (MaskedTextBox1.Controls[2] as TextBox).Text;
But working with events seems to be a more proper way.
Thanks,
Mike

What is causing the postback? I assume the Button.
Put your code in the event handler of the postback initiator instead of the load event handler. That would then be the Button_Click event handler if my assumption is right.

Hi Allm
I have created a MaskedTextBox UserControl with a number of properties (Value, MinValue, MaxValue etc.) The UserControl works but I am not able to actually get the Value from the UserControl in the main apsx page. In short what I have done:
UserControl with a TextBox, a RangeValidator and some JavaScript to take care of the formatting.
In the main page:
<uc1:MaskedTextBox ID="MaskedTextBox2" runat="server" MinValue="-10000" MaxValue="10000" ErrorMessage="Value must be between {0} and {1}" Required="true" Display="None" /><br />
<br /><br />
<asp:Button ID="Button1" runat="server" Text="Button" /></div><br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
And in the code behind on_load event:
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
if (Page.IsPostBack)<br />
{<br />
Label2.Text = MaskedTextBox2.TextValue.ToString();<br />
}<br />
}<br />
But the value of the TextValue property is not available because the UserControl is loaded after the Page_Load event. How do I get the TextValue of the UserControl in the PostBack of the aspx page?
I would prefer not to use Session or ViewState because I would like to use the UserControl as I would use a 'normal' TextBox. Any ideas out there?
Kind regards,
Mike

Can you post the code used for the TextValue property? Use ViewState for the TextValue property. I believe you must be using String variable instead.

For some reason the code below to fill a datagridview works very intermittently, I was wondering if anyone could spot any coding horrors my inexperience may have allowed in there...
dateFrom = "CONVERT(DateTime, '01/" & MonthDD.SelectedIndex + 1 & "/" & Trim(YearDD.SelectedValue) & "', 103)"
If MonthDD.SelectedValue <> "December" Then
dateTo = "CONVERT(DateTime, '01/" & MonthDD.SelectedIndex + 2 & "/" & Trim(YearDD.SelectedValue) & "', 103)"
Else
dateTo = "CONVERT(DateTime, '01/01/" & Trim(YearDD.SelectedValue + 1) & "', 103)"
End If
SQLString1 = "SELECT [InvoiceNo], [ClientCode], [Date], [PnrCode], [Initials], [Amount], [AccyNC4000], [DisbsNC4090], [DKpgmgmtNC4050], [CorpTaxNC4021], [PersTaxNC4030], [PayrollNC4070], [ExectrustNC4031], [CoySecNC4010], [OtherNC4080], [AccyNC4000]+[DisbsNC4090]+[DKpgmgmtNC4050]+[CorpTaxNC4021]+[PersTaxNC4030]+[PayrollNC4070]+[ExectrustNC4031]+[CoySecNC4010]+[OtherNC4080] as [Total] FROM [transaction] WHERE ("
If PartnerDD.SelectedItem.Value <> 0 Then
SQLString1 = SQLString1 & "([PnrCode] = @PnrCode) AND "
End If
If ClientCodeDD.SelectedItem.Text <> "Select a Client Code" Then
SQLString1 = SQLString1 & "([ClientCode] = @ClientCode) AND "
End If
SQLString1 = SQLString1 & "([Date] >= " & dateFrom & ") AND ([Date] < " & dateTo & "))"
SqlDataSource1.SelectCommand = SQLString1

You should use paramertised queries rather than injecting values in to the SQL. See SQL Injection Attacks and tips on how to prevent them[^]... Actually later on you are using parameters!  Why use two different ways of doing things?
Other than that I can't really see what you are trying to do. The code is quite difficult to read.
Perhaps you need to isolate this SQL and see how it runs on its own with various inputs to see if you can determine where exactly it is failing.

because the dates come from a dropdown that contains a list of months and a dropdown that contains a list of years, these have then to be concatenated into Date Format with variables that I'm using in the SQL statement. This is going to be running on a company intranet so I'm not that worried about SQL Injection attacks
Code to populate the drop downs runs in not page.ispostback
thisMonth = Month(Now())
thisYear = Year(Now())
For j = thisYear - 5 To thisYear + 5
YearDD.Items.Add(Str(j))
Next
MonthDD.Items.Add("January")
MonthDD.Items.Add("February")
MonthDD.Items.Add("March")
MonthDD.Items.Add("April")
MonthDD.Items.Add("May")
MonthDD.Items.Add("June")
MonthDD.Items.Add("July")
MonthDD.Items.Add("August")
MonthDD.Items.Add("September")
MonthDD.Items.Add("October")
MonthDD.Items.Add("November")
MonthDD.Items.Add("December")
MonthDD.SelectedIndex = thisMonth - 1
YearDD.SelectedIndex = 5

Statistiacally most attacks are insider jobs.

Or you could do that to create a DateTime object then pass that as a parameters.

OK, had a go at getting that variable as a parameter as well, works OK, but I still have the same problem, if I change the year or the month drop down and repost the page, it doesn't seem to run the query, as soon as I change the ClientCode or Partner dropdown and repost it, it runs the query with the correct Dates selected as well... This is going to be something really simple I feel and I'm going to look like a right tool...
SQLString1 = "SELECT [InvoiceNo], [ClientCode], [Date], [PnrCode], [Initials], [Amount], [AccyNC4000], [DisbsNC4090], [DKpgmgmtNC4050], [CorpTaxNC4021], [PersTaxNC4030], [PayrollNC4070], [ExectrustNC4031], [CoySecNC4010], [OtherNC4080], [AccyNC4000]+[DisbsNC4090]+[DKpgmgmtNC4050]+[CorpTaxNC4021]+[PersTaxNC4030]+[PayrollNC4070]+[ExectrustNC4031]+[CoySecNC4010]+[OtherNC4080] as [Total] FROM [transaction] WHERE "
If PartnerDD.SelectedItem.Value <> 0 Then
SQLString1 = SQLString1 & "([PnrCode] = @PnrCode) AND "
End If
If ClientCodeDD.SelectedItem.Text <> "Select a Client Code" Then
SQLString1 = SQLString1 & "([ClientCode] = @ClientCode) AND "
End If
SqlDataSource1.SelectParameters.Item("dateFrom").DefaultValue = dateParam
SqlDataSource1.SelectParameters.Item("dateTo1").DefaultValue = dateParam1
SQLString1 = SQLString1 & "([Date] >= @DateFrom) AND ([Date] < @DateTo1)"
MsgBox(SQLString1)
SqlDataSource1.SelectCommand = SQLString1

Fixed it.... had to make an invisible asp:label so I could pass the value from a controlparameter and bind the labels text property as the value...
-- modified at 15:57 Wednesday 27th June, 2007 cos I'm a prat and wrote commandparameter instead of controlparameter :p

What does this have to do with ASP.NET (a framework designed for writing web applications)?
This should go in the SQL Forum.

It's sounding to me like you might be needing to do some string formats. Check out this link... I think it's the answer to your question.

Hi friends,
I working in a module which would look like Windows Explorer, a Folder tree on the left and a File and folder list on the right.
Loading the folder is working fine and loading the right pane to the selected tree node is also done. The right pane data are loaded dynamically. Each files and folders are Linkbutton generated on runtime. I am not able to retain that controls when any of the link button is clicked. I have added a Click event for the Linkbutton which would open that folder and loads the inner data. When the page postbacks, this linkbuttons are cleared and the Click event is not called since the Page lost that control.
Anybody have an idea to solve this problem?
Thanks in advance...

No Vasu. I have tried it.
The sad part is when the Page is postbacked all the Link Buttons created dynamically are cleared.
