Don't use a LinkButton[^] for this; use a HyperLink[^] instead.
Clicking a LinkButton will cause the current page to post back to itself and run through the entire page lifecycle. Your code will then call Response.Redirect, which will return an HTTP 302 response telling the browser to request a different page.
Clicking a HyperLink will cause the browser to request the correct page directly.

need to download file when user click on file .
|
|
|
|
|
The easiest way to do this is have a hyperlink to the file. When they click it, their browser will download it. You can also look into Response.TransmitFile().

2) Take the extracted images and convert to .txt & also convert the text inside the pdf to plain text(.txt) -- 2nd API.
OR 2nd way :-

Hi people,
Could you please help me on how to convert an html document to a pdf document. I need like a free third party tool that can do the job. I've tried iTextsharp but it won't copy the styles from the html document to the pdf file. I've also tried Winnovative, but it prints out a watermark specifying that I am using a demo version.
I need a solution that can convert the file to pdf without the watermark but with the styles. Thanks a lot in advance guys.
Kind Regards,
Denzil.

Hi Mohammed, I've also used Evo, but it's a demo version, and the watermark specifying that it's a demo version still prints out on the output.

You can try its trial period till it expires and if it fits for your requirement fully then you can think of purchasing the license.

I was giving a project to remove all silverlight components from a website. my question is this possible or should I just rewrite the site as an asp.net wed application
|
|
|
|
|
It depends. Is it a silverlight project? Then yes, you likely should rewrite it. Or, is it an asp.net web app that loads some pages that have silverlight?
I think either way you'll have to re-write whatever the SL was doing.
Good luck.

Hi, I need Chat box component (like as FB chat room) for a social network site.
|
|
|
|
|
And which of the hundreds of freely available components did you try and why did they not meet your needs? You have to give us something to go on here. There's no reason in your question why I shouldn't sell you my million dollar chat box component, right? It's really shiny.

I use WebMatrix 3. I've got an ASP.NET Web Pages site that draws fractals, it uses a SQL Compact database and works fine locally.
But after I published it to the Azure Cloud and tried it, I get an error in the Database.cshtml that it doesn't work. Error: Failed to find or load the registered .Net Framework Data Provider.
The URL is: http://aljo-fractals.azurewebsites.net Click on the option Database and you'll get to see the error.
I guess I need to add a framework to use the database, where do I get that?
This must be easy to fix, but how...

Hi,
I have developed an ASP.net VB application on 1.1 in which we insert certain data into a particular table which is on sybase.
My table structure:
CREATE TABLE dbo.at_ip_disbursement
(
doc_id numeric(7,0) IDENTITY,
doc_type varchar(30) NOT NULL,
rim_no int NOT NULL,
item_type varchar(80) NULL,
customer_name varchar(80) NOT NULL,
rsm_name varchar(80) NOT NULL,
branch_no int NULL,
business_unit varchar(30) NOT NULL,
input_dt datetime NOT NULL,
Category varchar(30) NULL,
deferral_details nvarchar(600) NULL,
days_deferred int NULL,
Deff_Expdt datetime NOT NULL,
Deferred_Dt datetime NULL,
rm_comments nvarchar(600) NULL,
creator_id varchar(10) NULL,
modifier_id varchar(10) NULL,
status char(1) NOT NULL,
App_Authority nvarchar(600) NULL
)
LOCK ALLPAGES
go
IF OBJECT_ID('dbo.at_ip_disbursement') IS NOT NULL
PRINT '<<< CREATED TABLE dbo.at_ip_disbursement >>>'
ELSE
PRINT '<<< FAILED CREATING TABLE dbo.at_ip_disbursement >>>'
go
Now the piece of code where the insert takes place:
Public Shared Function AddDisbursement(ByVal DocType As String, ByVal Rim As Int32, ByVal CustomerName As String, ByVal RSMName As String, ByVal BranchNo As Int32, ByVal Business As String, ByVal InputDate As String, ByVal Category As String, ByVal DeferralDetails As String, ByVal DeferredDays As String, ByVal DefExpDate As String, ByVal DefDate As String, ByVal RMComments As String, ByVal CreatorId As String, ByVal App_Authority As String, ByVal Item As String) As String
Dim logger As SKLogger = New SKLogger
Dim connMosaic As String = System.Web.HttpContext.Current.Session("connStr").ToString()
Dim cmdText As String
cmdText = "INSERT INTO at_ip_disbursement(" & _
"doc_type, " & _
"rim_no, " & _
"customer_name, " & _
"rsm_name, " & _
"branch_no, " & _
"business_unit, " & _
"input_dt, " & _
"Category, " & _
"deferral_details, " & _
"days_deferred, " & _
"Deff_Expdt, " & _
"Deferred_Dt, " & _
"rm_comments, " & _
"creator_id, " & _
"status, " & _
"App_Authority, " & _
"item_type) " & _
"VALUES (" & _
"?," & _
"?," & _

"?," & _
"?," & _
"?," & _
"?," & _
"?," & _
"?," & _
"?," & _
"'A'," & _
"?," & _
"?)"
Dim conn As OdbcConnection = New OdbcConnection(connMosaic)
Dim cmd As OdbcCommand = New OdbcCommand(cmdText, conn)
cmd.Parameters.Add("@DocType", OdbcType.VarChar).Value = DocType
cmd.Parameters.Add("@Rim", OdbcType.Int).Value = Rim
cmd.Parameters.Add("@CustomerName", OdbcType.VarChar).Value = CustomerName
cmd.Parameters.Add("@RSMName", OdbcType.VarChar).Value = RSMName
cmd.Parameters.Add("@BranchNo", OdbcType.Int).Value = BranchNo
cmd.Parameters.Add("@Business", OdbcType.VarChar).Value = Business
cmd.Parameters.Add("@InputDate", OdbcType.Date).Value = InputDate
cmd.Parameters.Add("@Category", OdbcType.VarChar).Value = Category
cmd.Parameters.Add("@DeferralDetails", OdbcType.VarChar).Value = GetNull(DeferralDetails)
cmd.Parameters.Add("@DeferredDays", OdbcType.Int).Value = DeferredDays
cmd.Parameters.Add("@DefExpDate", OdbcType.Date).Value = DefExpDate
cmd.Parameters.Add("@DefDate", OdbcType.Date).Value = GetNull(DefDate)
cmd.Parameters.Add("@RMComments", OdbcType.VarChar).Value = GetNull(RMComments)
cmd.Parameters.Add("@CreatorId", OdbcType.VarChar).Value = GetNull(CreatorId)
cmd.Parameters.Add("@App_Authority", OdbcType.VarChar, 1200).Value = GetNull(App_Authority)
cmd.Parameters.Add("@Item", OdbcType.VarChar).Value = GetNull(Item)
Try
conn.Open()
cmd.ExecuteNonQuery()
Catch ex As Exception
logger.LogException("AddDisbursement", ex.ToString())
AddDisbursement = ex.Message
Finally
cmd.Dispose()
conn.Close()
End Try
'Return True
End Function
Now through javascript i allow user to input only 500 Characters(which works perfectly). Once the user submits data (say for example 400 characters) which is under the field "App_Authority" i get the following error:
ERROR [HY000] [INTERSOLV][ODBC SQL Server driver][SQL Server]ct_param(): user api layer: external error: A data length of 399 exceeds the maximum length allowed for CHAR data.
The same happens when i try to insert data into fields "RMComments" and "DeferralDetails"
Kindly advise me.
Thanks in Advance

Above is varchar, but in the table, you made it nvarchar,
It's a mismatch, that involves unicode I think, in which one is double the space of the other,
varchar is a 8bit codepage
[edit]
adjust your column in the table to take 1200 or whatever the value is suppose to be or vice versus
App_Authority varchar(1200) NULL

I need to add hot keys to my ASP.net MVC3 application. please give me any ideas on the best way to implement this in MVC?
for eg:
go to home page of my application when Ctrl + Q is used
to log_out when Ctrl + K is used
|
|
|
|
|
JQuery hotkeys is probably the best way to do that, but please don't override common functions like ctrl-Q which the user has an expectation for already. If you change the behavior of that key, users won't like it.

I posted my real answer on Facebook. However, what you need to do here is go back to basics and learn some SQL. Your question is like, Day 2 of a basic SQL class. I don't even know how to answer it other than to give you the ANSI join syntax, which is freely available on Google. So, I don't understand why you are asking people on here to help you? You need to learn the basics of the language first, so you can ask intelligent questions.
http://www.w3schools.com/sql/[^]
select <columns list>
from <table>
join <table2> on <table.column> <operator> <table.column>
That's tripping you up? Please explain why.
|
|
|
|
|
This worked
var res =(from tb1 in dt1.AsEnumerable()
join tb2 in dt2.AsEnumerable() on tb1["A"] equals tb2["AA"]
Gridview.Datasource = res;
Gridview.DataBind();
anyways thank you

In your question you did not say you wanted Linq style stuff, didn't even say you were using c#. Look at your answer and your question and ask yourself if it's possible to go from one to the other.

Anyway i shall strive to frame my question better the next time around,thank you jasmine.i have another question for you.suppose i have the row index of a gridview (that i obtain on clicking the first cell in that row) how do i obtain the value of 3rd cell in that very row.If my question was ambiguous pardon me.

Keep in mind that I get an email copy of your comments even if you delete them later. I'm just trying to help you get better answers. Whenever you post a question, please read it carefully before posting, to make sure you've given the information needed to answer the question completely.
When working with GridView object, it can be tricky to get values from the data - much better to get those from the underlying dataset itself. But, you can sometimes get it this way...
(because it's zero-indexed, this would be the third cell from the left)
myGridView.Rows[myRowIndex].Cells[2];
The problem is, the object living at that reference is a "TableCell" object, and you'll have to extract the data value out of there somehow. Remember, the GridView is the VISUAL object, not the data object. The best way to find data when the user clicks on a row in a GridView is to use the primary key and go back to the original DataSet which is bound to the control.
