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 ?

Atually the validation controls are colled only on a post back. You will need take help of javascript to get the validations done in case of OnclientClick event

This will give you the value on the text box
(Change the Cell[3] to the column number you want)

string str = ((TextBox)gridView1.Rows[e.RowIndex].Cells[3].Controls[0]).Text;

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

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!

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

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?

We use MS Indexing Service to catalog our sites and search the catalog using VB ASP.Net. Works well.

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?
