What are the events are fired during the Datagrid execution?

DataGrid is a server control. When page is processed, it calls Render() method in each control which writes it's output to the response.

1 - ^\s, I guess. But that doesn't prevent entry, it shows a message. You use jscript to prevent keypresses

2 - Then set it to be disabled, and only enable it when you change the value

3 - your code is a disaster, you should read up on SQL injection attacks. Fixing your code so it's safe will also fix the issue you're having.

Hi,
Thanks for your reply.
I am new to web development.

I want to stop user to entering white spaces. I used your regex but it display the error message if user enter any values other than white space . I need the regex which is opposite to it.

2. My calendar is a JavaScript calendar..can u tell me how to enable it. I disabled the textbox at the declaration time like

<asp:textbox id="strDate" enabled="false" onkeypress="return false;" runat="server" cssclass="bgcolor" width="100px">

if (!document.layers)
{
document.write("<img src="cal1.gif" onclick="popUpCalendar(this, Form1.strDate, ">
\"dd/mm/yyyy\")' height=17 width=18> ")
}
</img>

3. can u suggest me something on SQL Injection so that i can resolve my issues.

^[^\s]*$

this won't match text with spaces or line breaks.

You should use parameterized queries or stored procedures to avoid them. Do a search for SQL Injection attack in CP - You will find useful articles.

Then try \s, I guess. ^ means not. Perhaps \S is whitespace and \s is not whitespace.

2 - you need to write javascript to enable the textbox, set the value and disable it again

3 - yes, if you want to be a programmer, I suggest learning how to use google and other search tools. There is at least one excellent article on this site on SQL injection, just type SQL injection into the search box.

Yes. But ^\s will assert the position at starting, AFAIK. "not" would be [^\s]

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 ?
