this can be done using script.
use the script function below..
function FindPrice(ctlCurrentPrice,txtDiscount,ctlCustomerPrice)
{
ctlCustomerPrice.innerText = Number(ctlCurrentPrice.innerText)-
Number(ctlCurrentPrice.innerText)*Number(txtDiscount.value)/100);
}
and use the following code inside the RowDataBound event of gridview..
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox txtDiscount = e.Row.FindControl("txtDiscount") as TextBox;
txtDiscount.Attributes.Add("onchange", "FindPrice(" + e.Row.Cells[0].ClientID + ",this," + e.Row.Cells[2].ClientID + ")");
}

1. I have the following tables in the sql server
(a) tblforms - This table contains all the form names of the project
(b) tbluserdetails - This table contains the user information
(c) userforminfo - this table contains the information about which form pertains to which user.
2. I have a web form named form management , there in the form , i have the dropdownlist and a gridview.
in the gridview , i have two columns (formname , checkbox)
Dropdownlist populates all the user names , and the currently selected user name in the dropdownlist selects the form name in the checkbox of gridview .
Now my question is , how should i select the form name for the particular user and leave the rest unselected in the checkbox.
According to my understanding , i should first populate all the formnames and then for the currently selected user in the dropdownlist , i should extract all the formnames for that user.Now for each form name(extracted for the user) i should loop for 25 forms (because i have 25 forms i the gridview).
Am I proceeding in the right direction ?

Best method would be to bind all the forms from "tblforms" table to the grid view. In grid view's RowDataBound event, query "tbluserdetails" table to find user has this form. If yes find the checkbox and check it.

i have another question.
The administrator is assigning the forms authorization to the user by clicking the checkbox parallel to the forms .
Now , I am going to tell you , the process of assigning the authorization to the user , which i implemented.
I select the form name which ever i have to assign to the user , then i click the save button , now lets say the user select ten forms, then i am iterating the gridview records , i mean putting each record into the loop , now the selected record will go into the database , the rest will be deleted.I mean if i have 25 forms , then iteration will take place 25 times.
Each record is being saved one by one in the loop.
Am i doing right ?

Yes it looks like. Alternatively you can create all insert statements and do a supply all at once which will be much faster as you are opening the connection only once.
|
|
|
|
|
in the user authorization table , there exists following fields
auto increment id
user id
formid
during the insertion the user id being fetched from dropdownlist
and the formod form the gridview
can u please elaborate the method u mentioned latter.

U mean SQL Bulk Copy ?
If it is that , then i need to create a teporary table which will have the userid and formid field.
because the user id lies in the dropdownlist and the formid lies in the gridview.

Hi
I have a strange problem
I have a button which has a cssclass in it and then in the stylesheet is where i specify the details for it.However it is having no affect on the button
below is the code:
<asp:Button CssClass="btcomp" ID="btspec" runat="server" OnClick="btspec_click" Text="Specification" />
.btcomp
{
background-color:#FFFFFF;
font-weight:bold;
width:200px;
height:500px;
}
any clues would be great
thanks
|
|
|
|
|
Are you sure that the stylesheet is linked to the page correctly?
|
|
|
|
|
sorted it, i needed to delete my cache for some reason
thanks

hi a-+s-+p-+,
Since you are applying CSS to Server side Control then either you are not specifying CSS class to style tag inside head as follows.
<head> <br />
<style type="text/css"> <br />
.btcomp<br />
{<br />
background-color:#FFFFFF;<br />
font-weight:bold;<br />
width:200px;<br />
height:500px;<br />
}<br />
</style> <br />
</head><br />
OR you are made separate CSS within the project but not linked CSS to page correctly as follows.
<link href="styles.css" rel="stylesheet" />
Hope this will solve your problem.
Thanks & Regards

Hello everyone,
I'm using ASP .NET 2.0 and I'm making a login page where I want to implement the remember me functionality such that that user be logged in the next time he comes incase he checked the remember me textbox. Now I've read in some articles over the web that you dont store the password in cookies coz it's potentially dangerous. so my question is how do we authenticate the user on the next time he logs in. Need a little guidance on this.
Thanks
Rocky

AFAIK, inbuilt ASP.NET login control have this option. If you are going for a manual implementation, use cookies for this. You can keep the user id in the cookie after encrypting, as saving password in the cookie is not secure. Each time check the session exist, if not check cookie existence. Read the user id from cookie and create a session for that user.
I implemented the same in our project by checking this in a base class where all my pages are derived. I have overridden OnInit and checked the cookie value there. Base class approach can avoid putting the cookie loading code in all the pages and it makes the maintenance easy.
Hope it helps

yea that look quite helpful. actually I'm using the login control but I'm handling the cookies manually. I didnt know it can do it automatically.

you mean all your pages were derived from one of your own class. I think thats a gr8 idea but now I've already made lots of forms. So did that parent class derived from the System.Web.UI.Page class? and then u derived all the other forms from that class u made ur self?
thanks a bundle, it was really good!

Yes exactly. This architecture gives easy way to group common functionalities like session checking to be written in single place. This method makes adding new features like this makes very easy.
You can create many base page classes. Assume in your website you have some pages that require authentication. Instead of checking session in page_load of all pages, create a class something named "AuthenticatedPage" where you do this session checking. Derive all your pages which require session check from this page. You are done and no need to add the code manually to all page_load. This gives high flexibility for maintenance.

I'm definately going to employ this strategy in my next project if not this one!

Hello genious...
I have one folder on sever say Projects
in which there are other 3 sub folders say small,nedium and large...
and in this 3 folders there are some files are stored..
if i want to download only one folder means projects so that all its others folders along with files can be download directly.

Once this project folder is created say Projects.zip ,i will download it easily...
Any Sugestions will be appreciated...

C#, VB J# whatever language you choose, uses the same base classes and also you can use a class library with is developed in J# in your C#/VB application without any problem.
