You need to setup a DNS server. If you are using Windows server 2003 or 2000 you will find this. XP won't support I guess.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Validators inside GridView

Hi Friends,
I am using GridView. Therein , i am making edit, addnew,delete all the three functions.

Now i am using Validators for the TextBoxes.
I am putting Validators in FooterTemplate for Addnew TextBoxes and in EditTemplate for Edit TextBoxes.

The Validators work for once. That is if i click AddNew LinkButton it will give me the Error message, but once i use Edit or Update and then try it again. It doesnt work.

I think it is losing the ClientID of the textbox?
I am not sure, but i felt so. Because earlier i was using the Ajax ValidatorCallout, which was displaying me Javascript Error message in this situation that, ControlToValidate is null.

Yes i even tried simple JavaScript
Eg: var NewName
NewName = document.getElementById("ctl00_ContentPlaceHolder1_GVGuide_ctl05_txtNewName");
alert(NewName);
for above line it is not able to Get the Control, NewName is always NULL

and
$get('<%=txtNewPhone.ClientID %>').innerText;

this one above code gives me error txtNewPhone doesnt exist, which is inside the GridView.
I am really lost...

All i am trying to do is get a decent grid which can work with validators.

Any Suggestion or Help would be highly appreciated.
If you need to see my code in detail please let me know i will post it here.

Thanks

Cheers

Store the user info in session variable.
On Page_Load event of each page check if session is not null.If it is null then redirect the user to the login page.

Multiply your decimal value by 100. Hey presto, it's now a percentage!

the value is in decimal format ex-0.90,and i want to show it as 90%,
i don’t think Multiplying with 100 solves my issue.

0.90 * 100 = 90. Stick a % sign on the end and voila - you've got '90%'.

I have a column in a report which displays an amount of currency. The currency is stored in sqlserver databse as 'Money' data type.

My problem is when I run the report it rounds off the value and does not disply to any decimal places. I want it to display the currency as 2 decimal places as this is how it is input and stored in the database.

anyone know how to do this?

You haven't explained which reporting tool you are using. However the .NET syntax to format a number to 2dp would be something like mynum.ToString("N2").

In your DataGrid1_PageIndexChanged event write:

this.DataGrid1.CurrentPageIndex = e.NewPageIndex;
this.BindDataGrid( );

Note:BindDataGrid is just to bind the grid with datasource.

HtmlTextWriter change settings before sending out

Leo Smith30-Nov-07 2:29

Yesterday I asked a question on how to retrieve a string of the raw html. Now the problem is that I have changed the data to byte[] and need to write it back to the HtmlTextWriter. The following is a code snippet if I am sending it to a Response value and not a text writer.

<code>
byte[] binBytes = null;
StringWriter str = new StringWriter();
HtmlTextWriter html = new HtmlTextWriter(str);
base.Render(html);

string s = str.ToString();
binBytes = binConverter.ConvertString(s);

System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
response.Clear();

Response.AddHeader("Content-Type", "binary/octet-stream");
Response.AddHeader("Content-Disposition",
"inline; filename=ConversionResult.bin; size=" + binBytes.Length.ToString());
Response.Flush();
Response.BinaryWrite(binBytes);
Response.Flush();
Response.End();

writer.Write(s); // Writer is the original HtmlTextWriter passed to the Render function
</code>

This snippet creates will creates a second window without and leaves the original window blank. I want to do away with the second window and have it create the modified text in the original window. So the question is how can I change the reply header information from the original encoding format and assign it to a new format (text to binary)?

Thanks,
Leo

Hi,
Is it possible to validate whether the given SessionID is valied or not? or in other words how do we identify whether the session is still active or not? for a given session id?

Thanks in advance

Any session id is valid as along as its in session. You can use the Session start event and session end event to do stuff and use the Session.IsNewSession to check within your pages if the session is new and redirect to the default page etc...

Right click the GridView --> Properties then click the event tab, then double click the RowEditing column; This will create an event for editing.
