Hello, good day!

I have a datagrid which have 32 columns that is Quantity, Unit Price and amount. The Quantity and Unit Price which contain data are bind from database. My problem is how do i write a code that calculate the amount of each rows in the datagrid and put it in the Amount column?
(Amount=Quantity * Unit Price)

Anyone can help me to solve this problem? Thanks.. Smile | :)

You can get the calculated value while fetching the records itself from the database. Or also you can calculate that in OnItemDataBound event of the datagrid.

here is the sample code which will help you:

public void dg_OnItemDataBound(object sender, DataGridItemEventArgs e)<br />
		{<br />
			if(e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)<br />
			{<br />
				DataRow drv = e.Item.DataItem;<br />
				Label lbl = (Label)e.Item.FindControl("lblValue");<br />
				lbl.Text = drv["Quantity"].ToString() * drv["Unit Price"].ToString();<br />
				DropDownList dd = (DropDownList)e.Item.FindControl("ddl");<br />
				string str = "javascript:return ValFunc(" + dd.ClientID.ToString() + ");";<br />
				dd.Attributes.Add("onChange",str);<br />
<br />
<br />
			}<br />
		}

Here label control will be there in your datagrid as template column and will display the calculated value.
Also you have to take care about the casting.

ResxResourceWriter

Hi,
Am developing a utility to read from a .resx file, edit the resource key contents, and then write it back to the .resx file.
Am able to change the file contents using ResxResourceReader() API and then changing the key and value, but am unable to write the tree back to the .resx file.

Any help would be of great help.

You basically use the ResxResourceReader class to read the resource, and should use the ResxResourceWriter class to edit the contents and overwrite the original file with this object.

I know nothing about web.config.

I am doing a web application. I stored my images in a folder which I created in the C:\... from the Solution Explorer window. I then added the existing item.

Finally from the toolbox standard, I added the image control and changed the image url.

Does this work? Unsure | :~

If the images are stored under the web root, then there will be no permissions issues. If the images are stored elsewhere on the hard drive, then by default, the ASPNET worker process does not have read/write permissions on any other folders.

The best practice would be to keep your images under the web root, particularly if they are just static images for display.

I guess that you are running your web site with the built-in web development server, if you run under the IIS, there should be no problem. The reason for that is that the built-in server services all the requests sent to it, it includes the dynamic web page like .aspx as well as the static files such as the images file. So to make it work with the built-in server, you simply group the image files in a folder, say Images, then you use the location tag to configure the authorization settings to allow all the users to access the Images folder.

Thanks a lot minhpc_bk,

But i want to ask you a question.

If i use the location tag to configure the authorization settings to allow all the users to access the my images folder.

It have any problem about security in my web site?

thanks

Well, this setting basically helps you overcome the built-in server issue, when you put your ASP.NET application in the live/production box, your web site normally runs with the IIS server instead of the built-in server. And this setting does not have any effect on the folder as the requests for the static files like the images are handled by the IIS, but the ASP.NET engine. I'm not sure which security you concern, but assuming you don't have any special setting for the images folder at the IIS level, all the users are basically able to access the Images folder with or without this setting in your web.config file.
