ASP.NET

Ok so I've been through some of the articles, had a rat through ASP.Net and solved most of the problems. Heres how it stands

I have a gridview gvProducts with autogenerate colums (I just want to see the data first)
I am using a ObjectDataSource which conforms to the required structure with Start & Max row parameters and rowcount etc.
The object returns a table, the grid displays the header text for each column but the is no data.

I have tested the proc (SQL 2005), debugged through the code and the proc returns a table with the required 19 rows, the object returns a populated datatable. The bloody grid won't show the data, only the header text.

The ASP Code

<asp:gridview id="gvProducts" runat="server" allowpaging="True" autogeneratecolumns="true" datasourceid="dsProduct" enablesortingandpagingcallbacks="True" pagesize="19"><br />
		<pagersettings mode="NextPrevious" /><br />
	</asp:gridview><br />
	<asp:objectdatasource id="dsProduct" runat="server" selectmethod="GetPagedForGroup" typename="CSD.OurLibrary.clsProduct" enablepaging="True" selectcountmethod="GetRecordCount" startrowindexparametername="iRowIndexFrom" maximumrowsparametername="iMaxRows"><br />
		<selectparameters><br />
			<asp:sessionparameter defaultvalue="1" name="iGroupID" sessionfield="GroupID" type="Int32" /><br />
			<asp:parameter name="iRowIndexFrom" type="Int32" defaultvalue="0" /><br />
			<asp:parameter name="iMaxRows" type="Int32" defaultvalue="19" /><br />
			<asp:sessionparameter defaultvalue="" name="sFilter" sessionfield="Filter" type="String" /><br />
		</selectparameters><br />
	</asp:objectdatasource>

I never use this objectdatasource stuff, but I assume GetPagedForGroup is a method that gets called. Have you set a breakpoint to see if it gets called and waht it returns ?

I'm just starting to do some ASP work so it is a bit of a curve!

This calls to the database and returns a datatable, and yes I have set the break points and it is working fine, the table is populated and the method returns it to the page.

As the grid actually displays the colums as the header text I assume it is working OK, I feel it is a setting on the gridview I have screwed up. Hence the minimisation of the formatting etc.

OK - what if you get rid of this object thingy, and instead call your data layer from code and assign a datasource/databind the control ?

Yep - works perfectly, gets the 19 rows, binds and displays the records. Dead | X|

Ok - got over the nth hurdle, the objectdatasource had enablepaging set to true.

Now to make it to as its told Sigh | :sigh:

Wrong problem - enable paging turned off the requirement for recordcount.
The root cause of the error was that I was returning a table for record count instead if an integer. D'Oh! | :doh:

Changed the extract to ExecuteScalar and solved the problem.

Hi guys, I have a recent project at work that requires me to work on a Search Engine that can do searching within the web application. I have no experience with it and it's proving to be quite a challenge.

Can someone point me in the right direction where I can find solutions/answers to how to design and create a search engine for an ASP.NET web application?

Google is a good answer Smile | :)

If the site is online, I'd tend towards using the site: feature of google to generate my searches.

We use MS Indexing Service to catalog our sites and search the catalog using VB ASP.Net. Works well.
Do a google on indexing service.

How do I store a text that contains < >s? ASP.net doesnt allow me to send these to the server? How is it handled usually? By replacing the tags with some symbols and changing it back to tags code behind, before using it?

How to Refresh ObjectList in Mobile Application?

1-Mar-08 9:45

The same way it's done in these forums. ASP.NET has nothing to do with it, it's all the browser. You do this to get a < - <. You use gt for greater than and amp for an ampersand.

Seeing as your question relates to mobile development, wouldn't it be better to post it in the 'Mobile Development' forum?

I started getting this warning when I compile, and I'm not sure why. How do I resolve it?

Things I've done recently (since yesterday) that I think might have prompted these warnings to start appearing:

1) Added a default.aspx/cs page to each sub-folder to prevent someone from browsing them. Is there a better way to do this?

2) Changed a library DLL, and then re-added a reference to it.

Anybody have any clue about this?

I've seen the temporary files go a bit wacky at times. Clear the temp folder listed and it should be fine.

As for preventing browsing, add entries in the webconfig

<location path="SubFolder">
  <system.web>
    <authorization>
      <deny users="*"/>
    </authorization>
  </system.web>
</location>

If I put that in the web.config, the sight can't get to the files it needs (in this instance, it's a folder called "css").

So you want to protect css files from being accessed? Just trying to understand what you're looking to do.

Noooo... I want to prevent people from browsing the folder itself. In other words, if they enter http://blah.com/css in their browser, I don't want them to see a directory listing. Right now, the way I'm doing that is to create a Default.aspx (and Default.aspx.cs) in the folder that redirects them to the root Default.aspx.
