Hi, check this out. I hope this is what you're looking for.
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Set the appropriate ContentType.
Response.ContentType = "Application/pdf"
'Get the physical path to the file.
Dim FilePath As String = MapPath("acrobat.pdf")
'Write the file directly to the HTTP output stream.
Response.WriteFile(FilePath)
Response.End()
End Sub
This is the site if you need it.

Hi
I am trying to write a file (with dynamic contents) from asp.net ( Code behind C#) on the server. My application is ending up with error when I am attempting to open the file in create mode.
I could not get past this statement and any help is greatly appreciated.
Thanks
Mahidhar

Sounds like the ASPNET account does not have write/create access. However, granting write/create access may be your easiest option but not the most secure one.

HI George,
Thanks for the good suggestion. I have modified the access permissions for the folder (i.e Server.MapPath) through OS File Manager(Explorer). Added ASPNET user as well as the default logged in users name with write & Execute permissions. Still I am unable to create the file from ASPX/.CS page.
Additionally I also enabled to write permissions for the site in IIS and restarted IIS on every attempt with no luck yet.
I am using VS 2003 on Windows XP Media Center edition.
Thanks for the tips as it gave me a direction to troubleshoot the issue.
Thanks
Mahidhar

Hi Frnd,
I am able to create and read files from Stand alone applications. I am also able to read files from default folder in IIS too. I had the problem to create a new file in IIS context.
Any way thank you for the attempt though it is deviated from the actual request.
let me know if you have faced similar problem or know the work around.
Thank you very much
Mahidhar

it is really agonising when u complete 70 percent of the coding then have to recode.
actually i was just about to complete my project when my pc was stormed by a virus.
so i copied the file from defaullt visual studio folder to removable drive
mind u " from visual studio folder" and not from WWW folder.
then i formatted and then indtalled the od again
then again i installed VS.Net
but then i could access it as it was showing one error message
"the project file cannot be found"
perhaps i have made mistake while copying.
the mistake being copying location was a vs folder not a IIS folder.
suggest me something through which i can work it out.

It sounds like you copied the solution files (*.sln, *.proj), but not the code files in the IIS directory. You should have at least one file (*.aspx) for each page in your project. If this is not the case, you have no hope of recovering your project. You wiped it out without backing up all the files.

Hello all,
This may be a repost but I can't find the original message.
I have a server asp:button control in the content place holder of a content page.
I create the event handler in the code behind through the properties editor. When I click on the button the server side event won't get fired.
I tried using a postback and an hidden input to change a value to achieve the same effect to no avail.
The hidden input's value does not get updated.
What am I missing?
Thank you.

Issue is:
1. when i first time I click the linkbutton on the grid - opens a page A in new window(window.open).
2. when i second time I click the another linkbutton on the grid - opens a page B in new window(window.open).
3. then I click the back button on the browser(gridpage) - now It automatically opens up the page A , Which I dont expect.
Please let me know how to avoid the window that get opened up when I go back on the browser.

Linkbutton column:
<asp:buttonfield commandname="proj_no" datatextfield="proj_no" headertext="Project No."
="" text="Project No.">
<itemstyle cssclass="ca_item_proj">
<headerstyle cssclass="ca_header_border">
Rowcommand:
If e.CommandName = "proj_no" Then
Dim i As Integer = Convert.ToInt32(e.CommandArgument)
Dim proj_no As String
proj_no = CType(ctrl, LinkButton).Text
Session("projectno") = proj_no
Response.Write("javascript:window.open('LinkAspApp.aspx','','scrollbars=yes,menubar=yes,height=600,width=800,resizable=yes,toolbar=yes,location=yes,status=yes');")

Hi,
I am using an ajax update panel with an image button inside, i want to show a message when i click tue button:
Protected Sub button_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles button.Click
Dim msgAlert As String = "alert('My message');"
Microsoft.Web.UI.ScriptManager.RegisterStartupScript(Page, Me.GetType(), "click", msgAlert, True)
End Sub
But when i click the button the message doesn't show, but if put the button outside the update panel the message does show.
i wonder if somebody knows how to show messages when we use an update panel.
Thanks,
Alberto Martinez

To change ObjectDataSource sorting order I use SelectingEventHandler
ObjectDataSourceValitutAsukkaat.Selecting += new ObjectDataSourceSelectingEventHandler(ObjectDataSourceValitutAsukkaat_Selecting);
void ObjectDataSourceValitutAsukkaat_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
{
e.Arguments.SortExpression = "SURNAME";
}
But how to change dynamically Objectdatasource sorting collation ?

But how to change collation order in sorting ?
Tableadapter table default locale is "Finnish", but in runtime I want use different collations
|
|
|
|

What are you binding your objectdatasource to? If it is a gridview, all you have to do is set the SortExpression to the data field you want to sort by when the column header is clicked.

I'm using ObjectDatasource with ReportViewer control and choose
different collation order.
|
|
|
|
|
I am not that familar with the ReportViewer control. I would assume it work similar to other controls, so it should have a sorting event that should get called when the control is requesting a different sort. If it does have a sorting event you could do something similar to what I have documented in my article I posted before.

There exists Selecting event as I write
ObjectDataSourceValitutAsukkaat.Selecting += new ObjectDataSourceSelectingEventHandler(ObjectDataSourceValitutAsukkaat_Selecting);
void ObjectDataSourceValitutAsukkaat_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
{
e.Arguments.SortExpression = "SURNAME";
}
Problem is, that this ObjectDataSource result is filled to tableadapter datatable, which
default locale is "Estonian" and result is sorted by SURNAME using Estonian collation
I want change this sorting collation dynamically to Finnish, swdish and so on.

Your problem is still the same. You have a Reportview control. You do something with that control to affect the sort. So an event off that control is where you will have to work with the sorting. By doing it in the objectdatasource_selecting method you will overwrite anything else you try to do. It will always force the sort to be the same.
Ben

Yes, I m doing before selecting, setting SortExpression
void ObjectDataSourceValitutAsukkaat_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
{
e.Arguments.SortExpression = "SURNAME";
}
and it sorts result by Estonian, now I want change it to Finnsih or Swedish
How to do that ?

I am not sure why Setting the SortExpression to "SURNAME" in the selecting event of the objectdatasource would sort the results by estonian. I am pretty sure that it will always sort that way since it is being set in the selecting event of the object datasource. Normally if you want to dynamically change the SortExpression you do it on the Sorting event of the control that the objectdatasource is bound to. In this case it is your reportViewer. So like I suggested before, on the reportViewer there is a sort method, you need to be using that method to affect the sort and then it will get passed through to your objectdatasource.

Problem is in the sorting collation. ObjectDatasource uses strongly-typed dataset which collation is Estonian. It selects data from database and puts data to that dataset table using that table default collation(Estonian)
I wanna change collation order already in ObjectDatasource not in ReportViewer control.
|
|

|

That sounds more like a culture setting thing. So if you set the Thread.CurrentCulture it should affect String sorting.

Works in this way
dsReportsTableAdapters.RAPORT_VALITUT_ASUKKAAT_KUIDO_STableAdapter ta = new dsReportsTableAdapters.RAPORT_VALITUT_ASUKKAAT_KUIDO_STableAdapter();
dsReports.RAPORT_VALITUT_ASUKKAAT_KUIDO_SDataTable tb = new dsReports.RAPORT_VALITUT_ASUKKAAT_KUIDO_SDataTable();
// set locale for table
tb.Locale = System.Globalization.CultureInfo.CurrentUICulture;
ta.Fill(tb, ....);
this.ReportViewerAsendus.LocalReport.DataSources.Add(new Microsoft.Reporting.WebForms.ReportDataSource("dsReports_RAPORT_VALITUT_ASUKKAAT_KUIDO_S", tb.Select("","SURNAME")));
