- ASP.Net >> Hide DataDrig column at run timeHi,
I want to set visible to false in my datagrid to all fields that are an ID.
How can I do this?
I'm using ItemDataBound event but it gives me an error: "Index was out of
range. Must be non-negative and less than the size of the collection.
Parameter name: index"
I have this code:
---------------------------------------------------------------------------------------------
Sub Item_Bound(ByVal sender As Object, ByVal e As DataGridItemEventArgs)
Try
Dim i As Integer = 0
Dim lCol As Integer = dg.Columns.Count()
Dim strH As String
For i = 0 To lCol
strH = dg.Columns(i).HeaderText().ToUpper()
If Left(strH, 2) = "Id" Then
dg.Columns(i).Visible = False
End If
Next
Catch ex As Exception
lblMsgErro.Text = ex.Message()
End Try
---------------------------------------------------------------------------------------------

- Frontpage Programming >> "Embedded" Pagination, how do I?I want to prepare a site that, when printed, the pages are all paginated to
A4. During composition I also wish to prepare a A4 pages.
The rationale that not all those who will need to access the material will
do so via a PC so I want a quick way of being able to produce a hard copy
version that is page for page like the website.
Any ideas please?

How can I get the value of an element of a web.config section?
For example:

<add name = "Name3" value = "Value3" />

I want to get the Value2 given the name of the section "B" and the

- IIS >> http File Downloads...I have a file that I'm trying to access via web. ie. www.mydomain/myfile. There is no extension on my file. I want the user to be prompted with the familiar open...close...save..download dialog box. This use to work with NT 4. I've since move the site to a Win2003 server. Why doesn't this work anymore?

- IIS >> Network Computers not showing upI have Windows 2003 server With SP1.
Approximatly 20 client workstations all running 2000 pro or XP pro.
The issue is when I browse the network the only computer that appears
under the domain is the server. Some of the workstation were migrated
from an NT4 domain, some where just purchashed and added new to the
network. The computers did show up before. I can not recall anything
that has changed to break this behavior. I checked the Computer browser
service on the workstations.
Am I missing something obvious? A new security measure?
Thank you in advance.

ASP.Net >> Open Excel files outside of Internet Explorer
Hi
I'm rendering my datagrid to a HTML stream with a .xls extension to open in Excel however it opens in the browser. Is there a way to programatically force it to open Excel? I know you can configure a setting in windows explorer to do this but i want to do this without any client interaction
Thanks

ASP.Net >> Open Excel files outside of Internet Explorer
Are you sending the content as an attachment with a name? That seems to work
for me... it launches Excel.

ASP.Net >> Open Excel files outside of Internet Explorer
Some code like this should do the trick.
Response.AddHeader("Content-Disposition","attachment;filename=myfile.xls");

- ASP.Net >> Groupname for Radiobutton kills Listener from Buttons?I have the following problem (especially with the groupname-attribut of the
RadioButton-Control) when developing in Visual Studio 2005 Beta.
I load an ascx-control in an aspx-page. This ascx-control itself creates
dynamically many radiobuttons in this way:
foreach (DataRow radiobutton_item in rbl_values.Rows)
{
RadioButton single_radiobutton = new RadioButton();
single_radiobutton.ID = "idname";
single_radiobutton.GroupName = "groupname";
this.Page.Controls.Add(single_radiobutton);
}
When loading the aspx-Page (and its controls) everything is fine and
groupname works as it should (I could only select one of the group). But when
a postback to this site occurs it seems that the listener of the
submit_button (placed on the aspx-Page) is killed. When I do not define the
Groupname of the RadioButton the submit_button works as it should (listeners
are not killed?!) but I can select more than only one radiobutton as I don't
have a group which they belong to.
I tried it already with an alternative:
single_radiobutton.Attributes.Add("name", mygroupname) instead of
single_radiobutton.GroupName = "groupname"; (seen in
http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.dotnet.framework.aspnet&mid=3079eba1-694a-431a-8ae4-a458895a37ec&sloc=en-us)
but this didn't help.
Do you knwo this issue?

- Frontpage Client >> Sharing Main Category ListI am wondering if anyone is able to shed some light on my dilema... I have 6
computers in an office that are now sharing a public folder (so its bascially
networked)... and we are beginning to create and develop and buyers
database... but here's where the problem lies... each of us have different
Main Category listings... so if we enter a person's details and try to put
them in a specific category no one else can pick that category up... is there
a way of simplfying the system so that when anyone of us open up the category
listing - we all have the same ones. And if we change anything in the Main
Category listing - then it changes on everyopne machine. Is this at all
possible??
I would really apprecaite any help.
Cheers

- Frontpage Client >> Not able to allow annonomous users to upload to my folderI am trying to place an upload form into my website. I followed the
instructions given by frontpage until I get to where it says right click on
the folder and deselect the option for allowing scripts. I can not do this
because that selection is "dimmed" as well as the options to allow annonomous
users to upload to the folder and for uploaded files to write over files that
are already there. How do I make these things come out of "dimness" so that I
can chose these options? By the way the allowing scripts option is not
choosen in its present form. Thanks
