Custom Server Controls :: 'sites On All The Servers Seem To Be Affected?
Nov 3, 2010
I'm hosting a few .net sites, some collapse with this error on an almost daily basis. I've moved the sites between servers, but sites on all the servers seem to be affected, so it is not just a bad install.This problem is acknowledged by MS and they have a fix here:http://support.microsoft.com/kb/975410But they don't provide the fix they talk about.Does anyone have any way to resolve this that does not need Microsoft (since Microsoft clearly aren't bothered to fix it)?

for some SQL queries I know the expected number of rows that must be affected by UPDATE, DELETE or INSERT statements. It could be a number such as 1 or a range such as 0-1 or 1-2 etc.
What is the best way to enforce that this is the number of affected rows and that otherwise an exception is thrown?
Also, can I limit the number of rows affected for UPDATE/DELETE/INSERT to say 1 row and otherwise get an exception?

I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
[Code]....
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

How would I add a (dropdown) list of available values for a custom server control property?
(Just like 'Visible' property of most controls has valid values of 'True/False' and nothing else can be entered or selected)

I am creating a custom server control, and I am wanting to include a JavaScript file in the dll file when the control is built. I have tried suggestions from the following websites:[URL] But after following the directions, If I use firebug to see what errors show up, the JavaScript functions that are being called all say "goNext is not defined" which leads me to believe the JavaScript file is not being added correctly.
Some information on what my control looks like
I have the JavaScript File in a folder called Script. The namespace of the project is CustomControl, and the Name of the project is MaskedDateTextbox.
In my AssemblyInfo I have the following:
<Assembly: AssemblyVersion("1.0.*")>

I've build a custom server control inheriting from WebControl. Basically it is a kind of button. All is working perfectly except one thing: the PostBackUrl is inoperative.
I probably forgot to implement something. Actually I just added the property PostBackUrl. Probably I should also implement an interface of call something.

I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).

I am trying to set up my web site on a stand alone server using Windows Server 2003 with IIS 6 which will access SQL server database (2008) on windows 2008 R2 server (also not in the domain) I am using form authentication and I have configured a custom identity account in IIS6. The local account is on both servers with same password and I have registered the account using aspnet_regiis.exe -ga The application pool in my iis6 has the custom local account set as the identity and my web.config file has the appropriate tags in the system.web element <identity impersonate="true" />
The problem is the local account does not seem to get passed to the sql server. Right now my iis settings are anonymous access (using the local acct vs isr) and no authentication specified under that - I did try Integrated and basic but it prompts for the username and password which I do not want. One article I read stated this: windows authentication does not support delegation (passing credentials from one server to another) and is limited to the one hop rule, only a primary token can be passed to a second server. windows
authentication on iis (all versions) gives the thread a secondary(impersonation) token which can not be used to access any network resouce

I have a control inherited from datalist because I want all the same functionality but with a couple of extra properties.
I have a method that goes off and gets the data inside the control (instead of using a separate datasource ID). It's reading it from XML into a datatable.
If on the code behind of the aspx page I put the control on I put a thecontrol.databind() in the page load, all works well.
However I'd rather not have to do this, instead the control should bind itself.
I gather it's something to do with the order of events but I'm not sure what to do about it.
I don't want to reinvent the datalist wheel, just add a couple of properties and get it's own data
Sample code (some code removed for clarity)

I'm having a dumb problem that is killing me. I have created the simpelest custom server control in VS 2008 c# called MyMsgBox. On the ASP page I put it in and register it. But, in the .cs file, when I try to call one of its functions I get the compile error that it is not found. The funny thing is that intellesense has it in the list and all of the functions with their given arguements. At the top of the .cs file I am using the namespace. The code for the custom server control is in the App_Code folder.
Also when I remove all refrences to its functions, the code compiles and when debugging the constructor for the class MyMsgBox gets hit.
<%@ Register TagPrefix="cc1" Namespace="CustomServerControls" %>
...
<cc1:MyMsgBox ID="msgBox1" runat="server" />
Task.aspx.cs
...
Using CustomServerControls;
...
this.msgBox1.confirm("Would You Like to add a new Task for this PO/Contract? ", "hid_f"); Error Message: 'Tasks' does not contain a definition for 'msgBox1' and no extension method 'msgBox1' accepting a first argument of type 'Tasks' could be found (are you missing a using directive or an assembly reference?)

I have some (probably very basic) questions about developing custom controls. I am wanting to derive a set of button controls, and the first one I have started on is a "DeleteButton", that has a additional property (DeleteConfirmationText) that is built into the OnClientClick attribute. To get that added, I overrode the Render method as follows:
[Code]....
This all works well. Now, I will add some logic to make sure that there is some text in the DeleteConfirmationText property, but that isn't the intent of my question.
What I am also wanting to do is to override some of the default property values, so I added that to the default constructor:
[Code]....
Now, in the designer in VS2008, and I look at the properties for the control, there isn't a default value shown in the "Properties" section, and the Causesvalidation still shows the underlying classes default value of "True". As well, in design mode, where the GridView control that containse my DeleteButton control would be displayed, there is an error box "There was an error rendering the control. 'Are you certain you want to delete this attorney?' cound not be set on property 'DeleteConfirmationText'. Here's the markup where I am defining the deletebutton control:
[Code]....
What am I doing wrong?
