Why doesn't this update panel work right?

I don't understand why this update panel doesn't work right.   It doesn't do a partial update.  Enable partial page rendering is set to true but clicking the button causes a full page post back.  The text of the label changes with the full post back. So, the event is firing and being handled but not with a partial post back.    This is with in a content page with in a Master Page.Does anyone see what I've done wrong? <asp:ScriptManager ID="MainScriptManager" runat="server" EnablePartialRendering="true"></asp:ScriptManager> <asp:UpdatePanel ID="pnlHelloWorld" runat="server" UpdateMode="Always"> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnHelloWorld" EventName="Click" /> </Triggers> <ContentTemplate> <asp:Label ID="lblHelloWorld" runat="server" Text="Click the button!"></asp:Label> <br /><br /> <asp:Button runat="server" ID="btnHelloWorld" OnClick="btnHelloWorld_Click" Text="Update label!" /> </ContentTemplate> </asp:UpdatePanel> protected void btnHe

Windows Update error message 84B30001 - SQL Server 2008 SP2 update fails


I am running Windows 7 Professional on a 64 bit platform and have Windows update on and selected to notify me when updates are available.  The other day, I received an error message that an update failed to install properly.  The update that failed is to update SQL Server 2008 SP2 - KB 2285068.  I have made several attempts to retry this update with the same result.  When I Googled the error message, all of the responses deal with the SQL Server 2008 SP1 update not SP2.  Couldn't find a solution to this problem - nor could I find one in the KB article - which basically explains details of SP2 and DOES give me the option to instal SP2 from here.  Don't want to take the chance and download it from here - maybe I should though.  Can usually find a solution to a Windows update error in Google - can't find one this time.

Any suggestions?

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!

Error message when selecting a row in webdatagrid



I have a webdatagrid control that is loaded by using an sqldatasource.  I have add and edit methods that behave correctly, however, I have a problem when I delete a row.   I can delete the row correctly from the datagrid and the database, but as soon as I select another row in the grid straight after, I get an error:

Microsoft JScript runtime error: 'undefined' is null or not an object


There are no events wired up to the row select, so it doesn't appear to be that.


Can anyone help?
