Re: How to clear HTML tables created at run time...

I'm not sure at what level you are manually coding to "get tables holding values" but if you are databinding a control to a datasource you can clear that control by binding to a null value.
If you are dynamically writing out HTML to the page then you should write it out to a Literal control and to clear it, you can assign it an empty string.

custom Paging in Grid View

4-Apr-08 0:36

Create a literal control:

<asp:Literal ID="Literal1" runat="server"></asp:Literal>

Add some HTML:

this.Literal1.Text = "... enter html here ...";

Clear the HTML:

this.Literal1.Text = string.Empty;

actually ..as we know gridview have own property of pageing..
this is default .

i do not want to do through allow paging.
but when we use default paging it fetch all the records from the database.
but in custom pageing it fetch only one page records at a time...

You have explained things a little better this time, the word "Custom" can have many meanings and it was not clear what you meant is your previous posts.
I'm glad to see that you have found an article that describes what you want to do, and how to do it.

hi all iam using a javascript file referenced inside a page. In this script iam referencing a JS function found inside the page. It is generating an error."The Controls collection cannot be modified because the control contains code blocks (i.e. )."

the code is as follows
External JS:

var ok =false
....some code
if (!answer)
{
ok=false;
CloseOnOk();
}

where CloseOnOk is a javascript function found on the page

function CloseOnOk()
{
if (ok==true)
GetRadWindow().Close();
else if (ok==false)
{
var txthidden=document.getElementById('<%=txtHidden.ClientID %>');
txthidden.value='1';
}
}

iam also referencing the external javascript from the page
<script language="javascript" type="text/javascript" src="../../Scripts/Confirmation.js"></script>

Any ideas??

Its not clear which piece of code is throwing the error but you can try commenting out the GetRadWindow().Close(); line to see if that is the problem.
Also try changing txthidden.value='1'; to txthidden.innerHTML='1';.

The error message is very clear enough. You can't use session in this event as it's not instantiated. Application_AuthenticateRequest is in the early stage of ASP.NET page life cycle. AcquireRequestState is the event where session will be created. So choose any event that fires after AcquireRequestState.

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

Hi!

I used Win XP Pro to develop an ASP.NET application. Everything is working fine in Win XP Pro. I published/deployed the same application into the Win Server 2003 Standard Edition. The website loads correctly, but I am not able to insert/update/delete data.

I have enabled Named Pipes and TCP/IP.

No errors are shown. The page just refreshes after I click the submit button without showing the new updates.

Hope someone can help me with this prob!

Thanks in advance.

hi all.i have developed this application to send email via ASP.Net(C#.net).now if i embedd an image using CID,the image is visible in outlook,but not in GMAIL,or Yahoomail even if i click to show picture.this,i guess is because the path of the image i am providing is of my system.and other systems can not access this path?the image dat i am embedding is not on the internet but its only at my system.so that means i cant provide any URL too.i dont want to send this image as attachment.i need to embedd it only.and i want it to be visible on Gmail or Yahoomail too..how can i do it?following is the code that i have written:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnSubmit_Click(object sender, EventArgs e)
{
string fileName = FileUploadReciepent.PostedFile.FileName;
fileName = fileName.Substring(fileName.LastIndexOf('\\') + 1);
string filePath = Server.MapPath(".") + fileName;
FileUploadReciepent.PostedFile.SaveAs(filePath);
ExcelReader reader = new ExcelReader(filePath); //Create an Excel file Reader
reader.setCurrentWorksheet(1); //Set current worksheet as 1
Array al = reader.getRange("A1", "A3"); //Get A1 to A3 from worksheet 1

foreach (object cell in al) //Loop through all the cells
{
TxtTo.Text += cell + ",";
MailMessage message = new MailMessage();
message.From = new MailAddress(txtName.Text);
message.To.Add(TxtReceipent.Text);
message.Subject = txtsubject.Text;
message.IsBodyHtml = true;
message.Body = Literal1.Text;
LinkedResource image = new LinkedResource("C:\\My Documents\\My Pictures\\anything.jpg");
image.ContentId = "anything";
//add the LinkedResource to the appropriate view
//htmlView.LinkedResources.Add(image);
SmtpClient client = new SmtpClient("smtp.xxx.com");

client.Send(message);
}
}

{
TextReader a = new StreamReader(FileUploadContent.FileContent);
Literal1.Text = a.ReadToEnd();
}

}
