Hi,
public void populate_menu()
{
DataSet ds = GetMenuData();
foreach(DataRow drow in ds.Tables["CATEGORY"].Rows)
{
MenuItem masteritem = new MenuItem((string)drow["category_name"]);
name = masteritem.Text;
get_id();
par_id = Convert.ToInt32 (ViewState["p_id"]);
if (par_id == 0)
{
Menu1.Items.Add(masteritem);
}
else
{
get_category_name();
ca_name = ViewState["cname"].ToString();
Menu1.Items[0].ChildItems.Add(masteritem);
}
}
}
In this I am unable to find the menu index of a particular category. In this I just tried by giving it as "0".
I want the menuindex based on the category name "ca_name".
cheers,
sneha

Why CoupanName is TextBox Type ?

Use
String CouponName;
CouponName =((DropDownList)row.Cells[3].FindControl("ddlCoupon")).SelectedValue.ToString();

I change my code as u suggest but now it show this error in same line of code'System.Web.UI.Control' does not contain a definition for 'SelectedValue' and no extension method 'SelectedValue' accepting a first argument of type 'System.Web.UI.Control' could be found
CouponName =(DropDownList)row.Cells[3].FindControl("ddlCoupon").SelectedValue.ToString();

CouponName will always contains some string value.Casting it to TextBox is meaningless.If you want to have TextBox based on the value of CouponName use some control logic to get it done.

I think you forgot to use text property.
CouponName.text="";

OK, well, given that the error message is in plain english, I'm not sure what to suggest. If you knew how to program, I'd suggest you break this up into as many lines as you can and step through in the debugger to work out what is going wrong.
As you don't know C#, I assume you're either in a class, or teaching yourself. If you're in a class, you should talk to your teacher. If you're teaching yourself, buy a basic book on C#, BEFORE you try to learn ASP.NET.
And if this is paid work, you are an utter disgrace, and should tell your client right now that you are stealing from them. If you work for a company, I'd expect them to go broke soon, hiring people like you. Your best way forward would be to buy a C# book and work through it, in the hope that when they fail and you look for another programming job, you find yourself actually capable of doing some programming and/or understanding basic error messages.
I assume you didn't write this code. Whoever did, isn't very good. It's horrible.
CouponName =((DropDownList)row.Cells[3].FindControl("ddlCoupon")).SelectedValue.ToString();
There are at least four ways that this code could blow up, it should be on at least 4 lines, with extra code to check the assumptions being made.

insead use:
string CouponName = string.empty;
CouponName = ((DropDownList)row.Cells[3].FindControl("ddlCoupon")).Text;

I have no idea how a textbox is getting involved in his code, but I suspect that Cells[3] has a textbox in it, instead of a drop down. He needs to break this in to steps and use the debugger to work out what is wrong. If he's capable of it.

Try this
CouponName.Text =((DropDownList)row.Cells[3].FindControl("ddlCoupon")).SelectedValue.ToString();

Its means your web pages contain more than one Server site Form Tag.

This can't be the whole page, as the form is not closed. If you have only one form on this page, there must be a form tag inside one of the controls you are including.

My guess is that the custom control what you have inside form is generating form.Debug and see the page controls collection and remove if it has more than on server side form.Only one Form runat server is allowed.

An Web Based Application is not like an windows based application which can be installed in any machine. Web Based Application only be hosted on Web Server (IIS) and other user can access it from there.
Your questaions says, you are asking about Web Setup Project.
Here you go :
Visual Studio Setups (Web Setup Part I)[^]
and
Ref[^]

Add web setup project to your exciting project.right click on your websetup project and select add-->project output.
a window should appear.just select ok.
Requirements for runing asp.net web page depends on target mashine but maybe you need:
1-iis
2-.net framework
3-if you use sql database ,you can install sql Express.

you need to read a VERY basic book on ASP.NET, because it's clear you have no idea what it is, or what it does. An ASP.NET application can only run on a web server that has ASP.NET. It gets to users via the web, that's what ASP.NET is for,

Hi im using VS2008 to upload and display images.
I have a control with an <asp:Image control in it... if i save the image to a file on the server and specify the ImageUrl of the control it works fine.
however i want to avoid writing the image to a file before displaying it.
first of all, can I use the <asp:Image control to display the output of a httphandler or do i need to use something like
<img alt=""httpHandler"" src=""../App_Code/ImageHandler.ashx?productid={0}"">
secondly, what if anything do i need to add to the web config? - under HttpHandlers if I add
<add verb="*" path="*" type="ImageHandler"/>
then the actual pages are not loaded - just the results of the http handler as soon as the page loads
(I guess this tells me the actual HttpHandler works as the image is displayed)
the control that wants to use the HttpHandler is in a 'Controls' directory, the HttpHandler is in the 'App_Code' directory
the ImageHandler.ashx file is:
<%@ WebHandler Language="C#" Class="ImageHandler" CodeBehind="ImageHandler.cs" %>
the ImageHandler.cs file is:
using System;
using System.Web;
using DataLinq;
using BLL = BusinesLogic;
public class ImageHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
int _productID;
if (context.Request.QueryString["productid"] != null)
{
_productID = Convert.ToInt32(context.Request.QueryString["productid"]);
}
else
{
throw new ArgumentException("No parameter specified");
}
Product product = BLL.ProductBLL.GetByID(_productID);
if (product != null)
{
context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite(product.Image.ToArray());
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
Thanks,
Chas

ok managed to get this working...
The HttpHandler ashx and cs files didnt need to be seperated and the ashx file needed to be in a different directory to App_Code
I put it in a new directory called HttpHandlers...
I couldnt figure out how to use the handler with an asp:Image control (if anyone has the answer to this that would be great) so i used the img control specifying the src (wrapped in a div specifying the innerHtml)
Cheers,
Chas

The typical way to do this, is to write a page that takes an id on the URL, and returns the bytes of the image from the db. Then your image source url will be something like myhandler.aspx?id=23
