| problem to insert value in dropdownlist on formView control Lior Levy 01:46:12 |
| |
Hello,
I'm using the SqlDataSource to insert value in dropdownlist, but i want to add a -- Add New -- at the end of the
list, but can't find a way to make it.
It works very well if I delete the SqlDataSource of the DropDownlist...
maybe the inserted item is overwrited by the SqlDataSource !!?
protected void FormView1_ItemCreated(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Insert)
{
DropDownList dropDownList1;
dropDownList1 = (DropDownList)FormView1.FindControl("DDL_ca");
if (dropDownList1 != null)
{
dropDownList1.SelectedIndexChanged += new EventHandler(DDL_ca_SelectedIndexChanged);
SqlDataSourceActions.ConnectionString = "ConnectionString";
dropDownList1.Items.Add(new ListItem("Add New1", "999"));
dropDownList1.DataSourceID = "SqlDataSourceActions";
dropDownList1.DataValueField = "CA_code";
dropDownList1.DataTextField = "CA_desc";
dropDownList1.DataBind();
dropDownList1.Items.Add(new ListItem("Add New2", "999"));
}
}
}
Any Ideas?

| Gridview Linq Query Bill Booth 21:18:10 |
| | Hi All,
I am trying to run a Linq query on a GridView Rows Collection that will
select the distinct contents of one cell. The query below will do the
job; however, it uses late binding. The variables cust and customerList
are both object types. I just cannot seem to get around this.
Any advice will be appreciated.
Bill
Dim gridList As GridViewRowCollection = CustomerGrid.Rows
Dim customerList = From cust In gridList _
Select cust.Cells(4).Text _
Distinct
For Each i In customerList
Debug.WriteLine(i)
Next

| Planning to keep the list alive Efran Cobisi 19:28:42 |
| | Hi all,
I am worried about the retirement of our lists as most of us are.
Therefore, I am making arrangements with Richard in order to move all of
the lists to my servers and keep them alive.
Hope to get back to you with some good news soon.

| User Configurable Menu Brady Kelly 16:01:05 |
| | I'm using a Menu control dynamically populated from a database table, and
need to provide the users with a facility to edit the menu items. Currently
I only cater for two levels of item, but three are now required. I would
like, if possible, to use the actual menu as a menu editor, when somehow
placed in 'edit mode', and I am considering changing the persistence to an
XML file to handle the hierarchical relationships better. My concerns here
are being able to limit menu items exposed to certain users only, and to
prevent manual editing of the XML file breaking the menu. Maybe an
automated backup that will go to 'last known good menu'. Suggestions on how
I may go about this will be most welcome.

| "Could not retrieve the current project" Eyvind Axelsen 16:50:50 |
| | Whenever I try to "Configure" an OleDbDataAdapter in the designer, it
presents a simple message box with the error message "Could not retrieve
the current project". This has happened before, but I have always been
able to get rid of by either restarting VS or rebuilding the entire
solution, but now I have tried this several times, in addition to
rebooting the computer and other kinds of voodoo, but to no avail. The
error shows up for every adapter in my project, of which there is quite
a few. Does anyone know of a solution?
Thanks,
Eyvind.

| debugging - Break on value change? Graeme Hood 15:39:24 |
| | I'm trying to find out where and when a value in a session variable is
gettting changed. I know I can use conditional breakpoints, but then I
would need to know what line of code to insert it into.
Is there such a thing as a condition watch that will stop execution as
soon as a variable has a specified value? Using VS 2008.

| Re: Validation of viewstate MAC failed. Patrick Newberry 23:03:53 |
| | On a series of pages with web forms I have, I found that when I start a
form, the leave it for a while and come back, when I press the submit
button I get a Server error in '/' Application.
Validation of veiwstate MAC failed. If this application is hosted by a
web farm or cluster, ensure that <machinekey> configuration specifies
the same validationkey and validation algorithm. AutoGenerate cannot be
used in a cluster.
I am assuming the session is timing out.
Is there anyway to prevent this from happening?

| Form.Show and events Graeme Hood 13:15:58 |
| | I have an app that seems to behave differently (possibly) after
installing VS2008 and .Net 3.5
Suddenly the event handler for combo boxes (SelectedItemChanged) is
getting called when Show() is called rather than when the combo item is
set prior to showing the form. Could something have changed in .Net to
cause this behaviour. This worked fine in a previous release of my
application some months ago and no code has changed.

| sitemap provider error Andrew Dunn 09:45:24 |
| | Hello,
I have an error with the sitemap provider. This is my sitemap section in
the web.config file:
<siteMap defaultProvider="=BH_SiteMapProvider" enabled="true">
<providers>
<add name="BH_SiteMapProvider"

When I run it I get the error:
The provider '=BH_SiteMapProvider' specified for the defaultProvider

Could anyone point me how to fix this?

| Web issues Dean Cleaver 09:10:07 |
| | Hi,
We've just had a problem occur that I have no idea how to fix or even find. This is the entirety of the event log error:
EventType clr20r3, P1 w3wp.exe, P2 6.0.3790.3959, P3 45d6968e, P4 extramile.ichange.web, P5 3.3.8.3, P6 487e902a, P7 1044, P8 22, P9 exception, P10 NIL.
extramile.ichange.web is our web assembly, and between that and the code below in other assemblies, there's 750,000 lines of C# and not a hint of where to look. It seems to function for a bit (I've seen login pages come up) but then something goes wrong, it doesn't call any of the Application_Error code, and just shuts down our app pool.
Any suggestions would be most appreciated.
Dino

| Error when creating new Web Site Andrew Dunn 05:02:31 |
| | Hi,
I'm trying to get back in to asp.net programming after an absence of 4
years. I am trying to create a new Web Site in VS 2005 and I get the
error:
Error 1 c:\inetpub\wwwroot\Andrews\Default.aspx: ASP.NET runtime
error: The given assembly name or codebase was invalid. (Exception from
HRESULT: 0x80131047) c:\inetpub\wwwroot\Andrews\Default.aspx 1
1 http://localhost/Andrews/
Error 2 The given assembly name or codebase was invalid.
(Exception from HRESULT: 0x80131047)
I've searched google with no luck. It's a brand new project so I haven't
even written a single line of code. Any ideas?

| AssociatedControlID in a custom templated control Bill Bassler 20:37:30 |
| | Can anyone point me to information on how to suppoer AssociatedControlID
for Label controls that might be dragged into templated panel-like server
control?
I have a control that I created that supports expanded and contracted
panels so that you can drag any controls into the panels at design-time.
However, when I attempt to set the AssociatedControlID property to
associate a Label that is also inside of the panel I get a non-sensical
design time duplcate control ID FindControl error on the Label control in
question for the first control that exists in the template. This would
seem to some kind of naming container issue where maybe the Label control
is attempting to find the control defined in the AssociatedControlID
property but it cannot.
Is there something maybe I need to implement in TemplatedControlDesigner
code to wire this stuff up?

| windows integrated authentication and Oracle Mark Aurit 20:34:35 |
| | I realize this is a little off-topic, unfortunately there isnt an ado news group. If someone can reply Im glad to take it offline.
My question is whether anyone has any experience (or knowledge) with an asp.net web app that interfaces with Oracle using windows integrated security. I believe I read somewheres that its possible, but it means running the accounts under a higher-level of privileges than a normal account does, something like that.
I have a security guy at work intrigued with sql server and integrated security, and I need to be able to tell him if the same can be done with Oracle and what the ramifications were.
Thanks, Mark

| sql server authentication with named domain account Mark Aurit 13:01:32 |
| | (I posted this yesterday but it didnt come back. Since its of important
to me right now Im going to post it
again, sorry if you are getting it twice)
Im creating an asp.net/sql server app; Id prefer to use a sql server
account to maximize connection pooling, our security guy wants
integrated security. We've reached an agreement where I can use a
single account as long as its a domain account, but Ive been unable to
figure out how to do so (if its even possible). Im thinking I either
need to use integrated security but force sql server to use a single
account, or use a regular connection string, naming the domain account
and password with Integrated Security=false.
Does want I want to do sound possible?
Thanks, Mark

Emne: Re: [DOTNET-WINFORMS] Styling multi content buttons in WPF
you could bind the controls that you want to change to the buttons
foreground property using a relative source
I have included an example below, watch out for wrapping.
There are 2 methods in the example. Setting the property binding
using the style does not work for the disabled foreground color, but
setting the binding on the control itself does,

How does one do the following:

Sc.MyArray[0] = "This is test 1";
Sc.MyArray[1] = "Thisis test 2";

| BUG??? Reflection and DEVPATH Yosi Taguri 19:04:05 |
| | hi there
I'm devloping an application which relies on assemblies that are not on my
path during devlopoing time.
I wanted to redirect all the assembly searches to a pecified place.
I've found the DEVPATH solution in help
I've added the DEVPATH as an envirinment variable.
restarted VS.NET so it will take effect (although it has no meanning for
vs.net)
I've created a config file as in the help:
<configuration>
<runtime>
<developmentMode developerInstallation="true"/>
</runtime>
</configuration>
and still I get an exception while trying to load thru reflection an
assembly that is in the DEVPATH.
using fuslogvw.exe I can see:
LOG: Processing DEVPATH.
LOG: DEVPATH is not set. Falling through to regular bind.
how can I activate it?????
what am I doing wrong?
