well, if u r using VS.NET 2005 u can do it in a very simple way by using an SqlDataSource object. You can configure the SqlDataSource object by appropriately selecting the server name, the database and the table u want to add the data. Then it automatically generates the SELECT,INSERT,UPDATE,DELETE statements or u can use ur own stored Procedures to do them.
then drag n drop a formview on to the application and set it's datasource to SqlDataSource.
e.g: FormView1.DataSource = SqlDataSource1;
FormView1.DataBind();

Not quite what I was looking for. I do have a datasource and what not but I am looking for a better way to grab the actualy entered data without having to declare 2 variables (Textbox and a integer) just to get the data from the formview.

I have a dynamic report engine which builds the report parameters from the stored procedures on SQL server. Everything works fine except the CustomValidator controls. When I add one for a Date Validation function I get the error "Condtional Compilation Turned Off". Does anyone know what this is from?
From .aspx page
<div id="EditForm" runat="server">
<asp:Table ID="parmTable" runat="server" CellPadding="3" CellSpacing="3">
</asp:Table>
</div>
From .aspx.cs file
case NMTCConstants.DATE_TEXTBOX:
// New Text Box
TextBox newDateTextBox = new TextBox();
newDateTextBox.ID = name + "_" + fieldTypeCode;
if (fieldLength != "")
newDateTextBox.MaxLength = Convert.ToInt32(fieldLength);
// New Masked Edit Extender
AjaxControlToolkit.MaskedEditExtender meeNew = new MaskedEditExtender();
meeNew.ID = name + "_MEE";
meeNew.TargetControlID = name + "_" + fieldTypeCode;
meeNew.MaskType = MaskedEditType.Date;
meeNew.Mask = "99/99/9999";
// New Image For Calendar
Image iNew = new Image();
iNew.ID = name + "_I";
iNew.ImageUrl = "~/images/Calendar_scheduleHS.png";
// New Calendar Extender
AjaxControlToolkit.CalendarExtender ceNew = new CalendarExtender();
ceNew.ID = name + "_CE";
ceNew.TargetControlID = name + "_" + fieldTypeCode;
ceNew.Format = "MM/dd/yyyy";
ceNew.PopupButtonID = name + "_I";
// New Custom Validator
CustomValidator cvNew = new CustomValidator();
cvNew.ID = name + "_CV";
cvNew.ControlToValidate = name + "_" + fieldTypeCode;
cvNew.Display = ValidatorDisplay.None;
cvNew.EnableClientScript = true;
cvNew.ErrorMessage = "Invalid Date";
cvNew.ClientValidationFunction = "validateDate";
// New Validator Callout
AjaxControlToolkit.ValidatorCalloutExtender vceNew = new ValidatorCalloutExtender();
vceNew.ID = name + "_VCE";
vceNew.TargetControlID = name + "_CV";
// Add Table Row
newTblCell = new TableCell();
newTblCell.Controls.Add(newDateTextBox);
newTblCell.Controls.Add(meeNew);
newTblCell.Controls.Add(iNew);
newTblCell.Controls.Add(ceNew);
newTblCell.Controls.Add(cvNew);
newTblCell.Controls.Add(vceNew);
newTblRow.Cells.Add(newTblCell);
parmTable.Rows.Add(newTblRow);
break;

I'm returning data from a sql query that populates a gridview however I want to modify what's displayed in 1 of the gridview columns based on whether or not a value returned in the sql query is null.
Basically, if the value in a particular row of data is null, I want to return an imagebutton that says "Add". If the value is not null, I want to return an imagebutton that says "Edit".
For example, something like this:
if(SqlQuery.SqlRow(20).SqlColumn(4).Value = null)
{
gridView.gridRow(20).gridColumn(4).Value = "<a href='addData.aspx'><img src='images/add_button.jpg'></a>";
}
else
{
gridView.gridRow(20).gridColumn(4).Value = "<a href='editData.aspx'><img src='images/edit_button.jpg'></a>";
}
Any idea how I can do this?
Thanks.

There are many ways you can handle this, one that comes to mind is On the column where you want to add this functionality
1.- Make that column a template column, this will allow you to Add controls to the column anyway you want
2.- add an Image Button on the column
3.- On the tag look for the source property of the image button
4.- Add something like this
<br />
<asp:imageButton <br />
id=imgButton1 <br />
runat=server <br />
ImageSource="<%(Eval(Container.DataItem, 'Column'))'Add.jpg':'Edit.jpg'%>" /><br />
About the property of the image I don't recall if it is Source or Image Source but you get the Idea

go to any login view in your website click on the smart tag and administer your website .
go to security and choose select authentication type and choose from the internet.
this should do it
and if it doesn't go back to your solution and delete the database it will be created again when u create a user.

Hi guys. I'm new to the MB and ASP.NET as well. I'm developing a Web portal that will drill down the customer's selection of products. The catalog is received via XML from a remote server. They would like the buttons to show up dynamically based on how many records are in the xml. I have all the code written to use XPath and find the specific contents and display the buttons, but since I don't have static buttons I am having a hard time with the click event. I've done some reading on this issue but I still don't quite grasp how to resolve it. It seems even if I set something like btnProduct1.Click += new EventHandler(btnProduct1_Click), the event never fires. After the click the page reloads and I lose the buttons. I am creating the buttons in the Page_Load but this just displays the same buttons I clicked, the event is still ignored. Is there a method I can use to click one of the buttons, and make a call to either a function or transfer to a new page? I just need to bring along the button text to the new page (I am currently loading it in Session.Contents) as those buttons will be created based on what was clicked. Sorry if this is a little long, I want to be sure it is clear what I'm trying to do. Thanks much for any feedback you can provide.

In order to get your postback working, you need to build the page exactly as was before the postback. In other words, you need to generate the page exactly as it was before the button was clicked. The the event will fire...
You can use a property of the buttons (for example the Tag property) to store information about which button was clicked. Determine the button pressed like so
<br />
if (sender is Button)<br />
{<br />
try<br />
{<br />
Button btnPressed = (Button)sender;<br />
}<br />
catch<br />
{<br />
}<br />
}<br />
(place the code in the event handler of your button...

Hi,
I was wondering, is there a way to fire a cross-page postback via C# code?
The problems is: I have one error page that displays an error occurred in another page. I don't want to pass the error text through a query string parameter, so I need this kind of approach. And, I cannot use Session to this.
Any hint?
Thanks in advance...

Can you not pass an error using a code or something.... like errorpage.aspx?e=123 and then check the number to display diffrent errors?
Why can you not use sessions?

We don't use Session because we have a load balance server configuration. I know, there's a approach for this, but we simply don't use.

Ah, uh, Server.Transfer()?

I'm new to the web and have a site with an SSL certificate but my local Dev machine does not. I just was implementing some security code from from the article "Switching Between HTTP and HTTPS Automatically: Version 2" by Matt Solars and I am having trouble testing it.
What do other developers normally do? Do I need to buy another certificate and install it locally or is there some option I can check on IIS for testing?

I downloaded and installed the SSL Diagnostics and am running IIS 5.1 but I do not see where I can create a certificate.
Where am I going wrong?

I am about to create a simple web app and I remember hearing about saving the application configuration in a database from school. This sparked my curiosity and have been searching the web for this technique but I was unsuccessful.
Does anybody know anything about this?
Please point me in the right direction or send sample code to learn from.
Thanks,

It is often to see this tag on a aspx page in which javascript is created with somepage.ashx http handler. Does anyone know how or any good articles talking about how this is done, how to cache the javascript in client side and how to triger a rebuild for the javascript if data changed on server?

You can append a random number querystring to the URL to prevent the useragents and proxy servers from caching your file.
