I'm not sure about the number six. Whatever the objects are present in ASP.Net, please let me know
|
|
|
|
|
I think you're getting confused. In classic ASP there were 5 objects available:
Request
Response
Server
Session
Application
In ASP.NET there are hundreds (if not thousands) - every object defined in the .NET runtime is available for use.

I have no idea what you mean, but I'd guess that it's not possible. Your server side creates html which is sent to the client when the client requests it. The client side does not exist while the server side is running.

Are both forms visible at once ? If so, then if they are not parent and child, I doubt you can do that, without polling using AJAX. If only one is visible at a time then the form will work out the new state for itself as it reloads.

Hi
In my webform(webform1.aspx), i have an iFrame control, along with with many web controls.
The "src" attribute of it refers to another webform.(webform2.aspx)
I want text to appear in the frame on clicking a button which fetches the
value from db. Am using a session variable to hold the text to be assigned for iframe.
And am using the following code in WebForm1.aspx
<br />
private void Button1_Click(object sender, System.EventArgs e)<br />
{<br />
Session["Cont"] = "This is a page";<br />
<br />
HtmlGenericControl frame1 = (HtmlGenericControl)this.FindControl("txtFrame");<br />
<br />
frame1.Attributes["src"] = "WebForm2.aspx"; <br />
<br />
Server.Execute("WebForm2.aspx");<br />
Response.ClearContent();<br />
}<br />
And in WebForm2.aspx,Page_Load(..)
<br />
if(Session["Cont"]!=null)<br />
{<br />
Literal1.Text = Session["Cont"].ToString();<br />
}<br />
The problem is when i click the button in WebForm1.aspx, along with actual text, a textbox with some characters is appearing in the iFrame though there's no other control in the target(Webform2.aspx) other than Literal control. 
Please help me in finding out the actual problem and its solution.
Thanks

Hi,
I have this code for my e-Commerce site (asp.net2 with C#) for adding items to Shopping Cart:
protected void btnAddToCart_Click(object sender, ImageClickEventArgs e)
{
string Price = double.Parse(((Label)DataList1.Controls[0].FindControl("PriceLabel")).Text).ToString("0.00");
string ProductName = ((Label)DataList1.Controls[0].FindControl("BookNameLabel")).Text;
string PictureURL = ((Label)DataList1.Controls[0].FindControl("picLabel")).Text;
int ProductID = Convert.ToInt32(Request.QueryString["idLabel"]);
if (Profile.cart == null)
{
Profile.cart = new ShopCart.myshoppingcart();
}
Profile.cart.Insert(ProductID,Convert.ToDouble(Price),1,ProductName,PictureURL);
Server.Transfer("ItemIndex.aspx");
}

Wow - what horrible code.
Try this:
if (DataList1.Controls.Length > 0)
{
Control c = DataList1.Controls[0];
Label l = c.FindControl("PriceLabel") as Label;
if (l != null)
{
string Price = l.Text;
Apart from the layers of code with no error checking, what on earth possesses you to do a double.Parse, then turn it back to a string ? If you want to make sure the value is a double, use double.TryParse, not a method that, if it fails, throws an exception.

This is quite a general error message.
You will need to check that all code referenced in the c# is correct at time of processing:
i.e. dont refer to a control in c# which doesnt exist in aspx page
For example you could be finding a control that doesnt exist or

the above might not exist or be transferring
Can you post your aspx?

The most logical way to do this, is to do it in the data layer.

By only requesting the rows you want to display, for example, select top 10 * from blah

I cant use select top 10 because of my requirment.
Because i am retrieving question accordingly to element id. If element 1 contain 15 question then i want to display only 10 question on a page. If it contain 5 question then i am retrieving question using next element id. If element 2 contain 10 question then i need to display 5 remenign question
from first element and 5 question from element 2 on next page.Next 5 question from element 2 need to bind to seprate data list.
I need to bind question from each element to seprate data list.

Why not use a filter in the datatable ? like "Select top 10 .." Or you may even consider using it in the actualy SQL query that you use to retrieve rows from DB.
OK,. what country just started work for the day ? The ASP.NET forum is flooded with retarded questions. -Christian Graus

How can u use filter to data table? I cant use top 10 query because accordingly to requirment i am getting question for each element. If first element contain 2 rows or rows less than 10 then i am binding that to datalist if it contain less than 10 and element 2 conatin 15 rows i want to display remening rows in next datailst. (if element1 conatin 3 rows then
i want to bind only remening 7 rows to second data list.I want to display only 10 record on a page)
So i am checking the condition if element 1 contain rows lessthan equal toor greater than 10.
Please tell me how can i do this.

Why do you need all the questions if you're not going to show them all ?
Sounds like you need to set up paging in your data layer.

I cant use paging because on each page once all questioin get displayed i need to display "Finish" button on last page. When he click on Finish then he can see all the summery of his survey and if he wish then before submitting survey he can change his answer by usnig previous link by which in on last page.

Perhaps you need only one datagrid then, to show all the questions ? Why do you have two ? Are they on different pages ?
I think you need to keep your previous answers in the session, or in viewstate, as you keep going back to the same page but showing a different page of questions.

I need two data grid because i want to show element name before displaying question in that element. In following fashion.
Element 1
- Question 1
- Question 2
- Question 3
- Question 4
Element 2
- Question 1
- Question 2
- Question 3
in that fashion. At the end of page <next> Link. On next page next question in the same element or any other element. In that ways. Admin can add any number of element in a selected category and any number of question in selected element. When user taken any survey he must see all the question followed by element name before displaying question in that element.

I would render the list of questions with nested repeaters. And, like I said, I would use the same page over and over to render questions and then use viewstate to store all the answers given so far.

Hi
I am using google search box on my intranet which is in an internal network.
I cannot seem to get it to work though is this because google search only works on a website and not an internal intranet.
any help would be great
thanks!

Google does not index your internal site, so why would it be able to search it ? If you don't expose it to the web, then google is not indexing it, simple as that.
