I took your advise and looked around; after putting together parts of other people's solutions I finally was able to get it right. Turns out I had to provide yet another callbackEventReference (with a function named Release(arg, context)) that would tell my server to do something, and I called that function from within the timer function... long story short, it worked and Im super happy

Hi i have a compare validator to validate a date field:
<asp:comparevalidator id="CompareValidator1" runat="server" type="Date" operator="DataTypeCheck" controltovalidate="txtDateOfOrder" errormessage="Please enter a proper date">
If i enter the date in the dd/MM/yyyy format the validator throws the error message as it wants the date to be in the MM/dd/yyyy format.
I want an dd/MM/yyyy format to be entered in my textfield.
my web.config has:
<globalization fileencoding="utf-8" requestencoding="utf-8" responseencoding="utf-8" culture="en-US" uiculture="en-US">
How can i make the validator to accept dd/MM/yyyy format????
Thank,
Sanded

I think your validation expression should read something like this:
\d{2}/\d{2}/\d{4}
but then again, this would also apply to mm/dd/yyyy...
why don't you use the CustomValidator control? that way you can write it the way you want it.

+ The simple way to know the id of the textbox at the client side is to view source the web page. Or you may want to look at the ClientID property from the server side code.
+ Also, to pass the value of the TextBox from the server side, you first need to get reference to the TextBox control like you are doing in the ItemDataBound, then you simply access the Text property of the control.

Greetings!!!
I have a problem, my web aplication has a Master Page and other page what inherits from the master page. The Master page has a treeview control and a herder. When a choose an option in a node from the treeview it displays the page but the postback appears in the selected page y also in the master page, and then the state of the treeview dissapears.
Waht can i do for avoid the postbak in the master page?
DIEGO
|
|
|
|
|
remove the MyBase.OnLoad from the MasterPages's VB File, if its not being used.
|
|
|
|
|
Ok, it would be a solution, but in the Load event there is the code for loading the treeview, if i use Atlas for ASP.NET ?
Thanks
|
|
|
|
|
I apoligize. I'm not familiar with Atlas for ASP.NET. I'll reasearch my responses better next time.

|
|
|
|
Ok, no problem and Thank you for your help.

Hey AreJay,
Try to implement client callback-enabled type tree view so that you wouldn't need to post back each time you select a node... AND you can find one right out of the box at this website!

The MasterPage in its nature is a user control which is then combined with the content page to produce the entire web page. So when a postback occurs, the whole web page is reloaded including the contents, header and the treeview control in the masterpage. In this case, if you only want to reload the contents, but the master page part, you may have a couple of options which you can consider:
+ Use frame (or iframe) like you see the online MSDN library web site.
+ Use Atlas (or Ajax in general) to dynamically load the output markup of the content web page only, then attach it to the current document at the client side.

Hi there
I'm working whit Visual Studio 2005 developing an ASP.NET 2.0 WebPage
I have a DropDownList Control with 2 options to select. I want to generate a validation message according to the selection made in the DropDownList Control. Any ideas???
THANX ¡¡
|
|
|
|
|
Server-side or client-side?
|
|
|
|
|
|
<br />
Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles DropDownList.SelectedIndexChanged<br />
Dim script As String = ""<br />
Dim ctrl As DropDownList = CType(sender, DropDownList)<br />
If ctrl.SelectedValue = "something" Then<br />
' Some Kinda Validation occurs<br />
script = "alert('This is what was selected: " & ctrl.SelectedValue & "');"<br />
Else<br />
' Some Kinda Validation occurs<br />
script = "alert('This is what was selected: " & ctrl.SelectedValue & "');"<br />
End If<br />
Me.ClientScript.RegisterClientScriptBlock(Me.GetType, "Alert", script, True)<br />
End Sub<br />
Is this what you had in mind?
|

just an fyi- make sure you provide the html control name when incorporating it within the script string... server controls sometimes take a different name once the result page is sent from the server back to the client.
Now, why would anyone be interested in server-side validation? Postbacks are very inefficient! To validate without making round trips to the server, look into using validation controls such as RegularExpression or CompareValidator.

I have created a report generator that creates an XML and passes it back to the browser as an Excel Doc. It works fine but the application lives within https and seems to kill the application with this error:
Microsoft Internet Explorer
Internet Explorer cannot download DataGrid.aspx from www.mysite.com.
Internet Explorer was not able to open Internet site. The requested site is either unavailable or cannot be found. Please try again later. This creates the XML based off user selection etc.....
Report_Gen.aspx
<br />
Dim dataDirPathXML As String = Server.MapPath("..\DataGrids\XML\")<br />
ds.WriteXml(dataDirPathXML & Session.SessionID & ".xml", XmlWriteMode.WriteSchema) <br />
Response.Redirect("..\DataGrids\DataGrid.aspx") <br />
This passes the XML back as Excel.....
DataGrid.aspx
<br />
Dim temp As String = Server.MapPath("XML\") & Session.SessionID & ".xml"<br />
If System.IO.File.Exists(temp) Then<br />
Dim streamReader As New System.IO.StreamReader(temp)<br />
Dim sBuilder As New StringBuilder(streamReader.ReadToEnd)<br />
Dim stringWrite As New System.IO.StringWriter(sBuilder)<br />
Dim htmlWrite As New HtmlTextWriter(stringWrite)<br />
Response.Clear()<br />
Response.AddHeader("content-disposition", "attachment;filename=" & Session.SessionID & ".xls")<br />
Response.Charset = ""<br />
Response.Cache.SetCacheability(HttpCacheability.NoCache)<br />
Response.ContentType = "application/vnd.xls"<br />
Placeholder1.RenderControl(htmlWrite)<br />
Response.Write(stringWrite.ToString())<br />
Response.End()<br />
End If<br />
I've been to the Server.MapPath("..\DataGrids\XML\") location and the xml is not being created.
What am I missing? I've tested this out-side the https and runs fine (local host or Live production server). Please any experiences with this kind of issue would be helpful.
