Basically, to change the current mode of the FormView you can use the ChangeMode method with the FormViewMode.Insert . Here, if you programmatically bind the datasource to the control, you can simply do a checking on the length of the datasource. In case of using a datasource control, you can create a handler for the Selected event of the datasource control, then you can check the AffectedRows to see if you need to change the mode of the FormView.

Hi,
Can anyone tell me, are there any 'tweaks' that can be made to the .NET framework to influence the type of HTML code that is produced?
Thanks in advance.

Hi there. What do you mean by that? Do you mean you want to edit the output html markup?

Hi,
Thanks for the response. What I meant was are there any settings within the visual studio environment that can be amended to influence the HTML content?

I m working on a project in asp.net 2.0.
I want to see "web form designer generated code" in dotnet 2.0.
In dotnet 1.1 we can see this in code behind file(e.g cs file). But in dotnet 2.0 code behind file does not show this.
How can we see this................
Do good and have good.

If you are using the Web Site default template, then have a look at the cache folder of the ASP.NET 2.0:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\XXXX If you use the Web Project 2005 template, you will see it in the same folder as the code-behind source file.

If you are looking to edit this code, then you'll find that it is all auto-generated now. Editing this code, as was possible in asp.net 1.1 was never recommended.

i donot want to edit it. I just want to see that code.

Outlook.Application o = new Outlook.ApplicationClass();
Outlook.MailItem myMail = (Outlook.MailItem)o.CreateItem(Outlook.OlItemType.olMailItem);
for (int i = 0; i < GridView1.Rows.Count; i++)

Hi
I am using Visual Studio 2003 and SQL Server 2000 to try and develop an E-Commerce website. Amongst others I have a Customers table, Suppliers table and a Roles table in the database. What is the standard procedure regarding storing usernames and passwords? At the moment I have Username and Password columns, as well as a foreign key column to the Roles table, in the Customers table as well as in the Suppliers table.
On my login page I have two radiobuttons so the user can specify whether they are logging in as a Customer or a Supplier. That determines then in which table I go to check the username and password. If the user is a valid user, the following line of code runs:
FormsAuthentication.RedirectFromLoginPage(userIndex.ToString(), ChkRemember.Checked);
The problem is that then I do not know how to use the Application_AuthenticateRequest() method in the Global.asax.cs. How would I specify in there which database table to be accessed to retrieve the roles? I tried using session variables, but they were not accepted in the Application_AuthenticateRequest() method.
protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
string[] roles = Access_Customers.GetCustomerRoles(HttpContext.Current.User.Identity.Name);
HttpContext.Current.User = new GenericPrincipal(HttpContext.Current.User.Identity, roles);
}
Am I missing the point completely here? Is there a better way of approaching this? Perhaps have all login data (usernames and passwords in one table)?
What is better from a security point of view to use in authentication and authorization: Cookies or Session variables?
Thanks.
Kobus

Hi
If you have defined roles, user and password in database, then why u r using Application_AuthenticateRequest(Object sender, EventArgs e) event of globaal.cs. You can directly access through database by forms submit button.

hi,
i want to know how should i return values from jagged arrays
public string[][] fync(Type webtype)
{
string[][] dimen= new string[3][];
dimen = getDetails(Type Webtype);
//how should i collect values in dimen
}
public string[][] getDetails(Type webtype)
{
//suppose ss is jagged array of dimension ss[3][]
//ie i have ss[0] = i have something
// ss[1]= i have something else
// ss[2]= i have some third item
return ss;
}
I hope i am doing right
help please
Thanks JIny

A jagged array is just an array of arrays. To create one you first create the main array, then create each sub-array:
string[][] ss;
ss = new string[3][];
ss[0] = new string[] { "Some", "strings" };
ss[1] = new string[] { "Some", "more", "strings" };
ss[2] = new string[2];
ss[2][0] = "Individual";
ss[2][1] = "strings";
When you get the jagged array from the function, you shouldn't create an array first. That only means that you create an array that you will just throw away. Just declare the reference for the array:
string[][] dimen;
dimen = getDetails(webtype);
---
b { font-weight: normal; }

Hi friends,
I just have one small doubt. I just inserted one button into the itemtempelate of a datalist and without writitng any code i ran the project. i tried the same with repeater and datagrid. but the button inserted was not to be seen in any of the above mentioned controls. Where as when i inserted a button to a form i was able to see that button. can anyone tell me why is it like that.

The DataList control is a data-bound control like Repeater, DataGrid. It means you need to bind a datasource to the control to create the UI, otherwise the control displays nothing. You can read more about how to use these controls in MSDN.

I'm playing by the rules, I have a theme setup with a skin file for all my control style settings.
For some reason as I'm working what appear to be defaults for styles for controls keep creeping back into my aspx page and overriding my .skin file.
I think when I bring up the properties of a component in the visual designer and change something innocuous like enableviewstate it's automatically setting a bunch of default style settings that I had just removed.
Is there any setting or way to prevent visual studio from setting any default style settings for components either existing ones or when putting new ones on the forms?
(or is this just a half implemented feature?)
P.S. And why doesn't it preview the page in the designer with the settings in the skin file (or is this again a half implemented feature?)

Hi there,
What do the generated style settings contain? Are they all related to positioning like left, top ...or something else?
