The ASP.NET AJAX library contains a control that does this, I am pretty sure.

You men using Session Variables in .Html files. I guess it will not be possible since the server will not process this pages in any way.. You shoul rename them to ASP / ASPX.

Then you can easily set the Session valiable like tis

Hi there. I am currently working on a website assignment and I need some desperate help.

I am using SQL Server 2005 Express Edition to store my data. I am using C# to write my site.

I have used the OleDb to connect to the database, and to write and read the values.

I have stored binary data (photo, jpeg) via Oledb, there is no problems at all.

However I am stuck big time with retreiving photos. I am also using OleDb to connect to the database, then I placed the retreived data into a Dataset. I was able to retreive other information (such as name, phone numbers) from the dataset. However I am unable to retreive the binary data from the dataset.

I've searched the web, it seemed everyone is using SQLDataReader, so I was curious it is possible to retreive binary data using OleDb at all?

HELP! Any feedback would be appreciated, thanks!

Why have you not used the SQL Server specific classes built in to .NET ?

What have you tried to access your data ? If a datatable has a limit to how big a column can be, perhaps you have to use a datareader to get that byte stream out ?

It's tough to tell what would be the problem as you haven't explained anything. Explain your problem in detail to get help.

Use Server.MapPath[^] to convert a virtual path to a physical path. Then use the stuff in the System.IO namespace to obtain details about all files in a directory and individual file information.

Custom paging with ObjectDataSource

Mycroft Holmes1-Mar-08 11:41

1-Mar-08 11:41

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 ?

Mycroft Holmes1-Mar-08 12:35

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

Christian Graus wrote:
GetPagedForGroup

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 ?

Mycroft Holmes1-Mar-08 14:12

Re: Custom paging with ObjectDataSource - feedback [modified]

1-Mar-08 14:12

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