In Quantity Column whether you having textbox or dropdownlist control.

|
|
|
|
And also tell the name of the primary key of your table,so that it will be helpful for us
|
|
|
|
|
In the OnRowDataBound eventhandler of a gridview you can check the values for price and quantity. Multiply them and show the value in your TextBox-object.
There are numerous examples to be found via codeproject.com or google.

Hi,
One way to do this by making all the columns in the grid as template columns.
then in the RowDataBound event using FindControl() method, set the value for Total label.
<br />
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem )<br />
{<br />
decimal Price = Convert.ToDecimal ( ((Label)e.Item.FindControl("PriceLabel")).Text );<br />
decimal Quantity = Convert.ToDecimal ( ((Label)e.Item.FindControl("QuantityLabel")).Text );<br />
Label TotalLabel = ((Label)e.Item.FindControl("TotalLabel"));<br />
TotalLabel.Text = Convert.ToString ( Price * Quantity);<br />
}<br />
<br />
Where did error begin?

Could you help me with a VB example? The "Price" column is a money type in the database and the "Quantity" column is an int type in the database. Here is the code.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
Dim TotalLabel As String
Dim Quantity As String
Dim Price As String
If e.Row.RowType = ListItemType.Item Or e.Row.RowType = ListItemType.AlternatingItem Then
End If
Decimal Price = Convert.ToDecimal ( ((Items)e.Item.FindControl("PriceLabel")).Text );
Decimal Quantity = Convert.ToDecimal ( ((Items)e.Item.FindControl("Quantity")).Text );
Decimal TotalLabel = ((Items)e.Item.FindControl("TotalLabel"));
TotalLabel = Convert.ToString(Price * Quantity)
End Sub
Thank you

I suggest you buy a book on ASP.NET and read it. A book on HTML is an even better idea. Your server side controls, build HTML, that's how they work. You can use css to give a control an absolute position, but I would always avoid that, the flow model of HTML works well for browsers that can be resized or on different size screens.

There are numerous commercial controls that do this, or you can use javascript to write your own.

thanks.

The beauty of web programming is that any site that does what you want on the client side, sends you the code. The issue, from memory, is getting the controls on the server side so you can access the file data posted. I think I ended up adding a finite number of controls and show/hiding them with javascript, instead of just dynamically adding them with script.

I have a major application with a few sub-applications.
One of my subfolder contains some utilities objects; that subdirectory is also inside my sub application.After conversion to 2.0 my main utility object(from the main app.) is ignoring the properties and methods that I have newly created so is the sub utility object...
Is legal to have the same folder in the main and the sub apps.?

Just a quick question, is the ASP.NET textbox control only capable of displaying pure text?
Is there anyway to embed a HTML link inside the textbox? Thanks!
If not, is there anything else I can use? Thanks!!!

Yes. The TextBox control renders to a HTML INPUT tag which can only display unformatted text.

You could create a 'fake' textbox using a DIV tag with the contenteditable=true attribute. Not something I've really tried to do myself, but search Google and you should find some more information.

Thanks for the reply.
Do you know if there are any 3rd party, and free (hopefully) textbox controls that support Hyperlinks?
Thanks!
|
|
|
|
|
FreeTextBox[^] is a free WYSIWYG textbox control for ASP.NET. It does a lot more than just hyperlinks, but I doubt you're going to find a control that just does hyperlinks. You'd have to write one yourself using the DIV approach I mentioned earlier.

Hi, thanks for looking
Im having a weird behavior and i dont know whats going on
I have the following code:
Dim panel As New Panel
Dim lbl As New Label
lbl.ID = "Label1"
lbl.Text = "Text"
panel.Controls.Add(lbl)
Dim lbl2 As Label = CType(panel.FindControl("Label1"), Label)
lbl2 is supposed to have lbl but it has Nothing
On the immediate window i get the following info:
?panel.Controls.Count
1
?panel.Controls(0)
{System.Web.UI.WebControls.Label}
System.Web.UI.WebControls.Label: {Text = "Text"}
AppRelativeTemplateSourceDirectory: "~/Test/"
BindingContainer: Nothing
ClientID: "Label1"
Controls: {System.Web.UI.ControlCollection}
EnableTheming: True
EnableViewState: True
ID: "Label1"
NamingContainer: Nothing
Page: Nothing
Parent: {System.Web.UI.WebControls.Panel}
Site: Nothing
SkinID: ""
TemplateControl: Nothing
TemplateSourceDirectory: "/V01/Test"
UniqueID: "Label1"
Visible: True
?panel.FindControl("Label1")
Nothing
How can i get the lbl control??
I cant just use index because i might have many controls inside the panel, i wont always know the order of the controls
Thanks in advance

Did you add the panel to the form control collection?
form1.controls.add(panel);

Thanks for the reply
Adding the panel to the form solves the problem
I hadnt tought about it
If im inside a class, how can i add those panels to the form?
(In httpcontext.current. i dont see anything like page) I can only think of sending page as a parameter, but is that my only option?
If you know any other, please let me know
Im using this functions where i insert and read controls from panels and the normal flow is insert them, and show them on the client, then read the options set on the client and save those to db
In this case, where this is not working is now that im doing this directly (Not sending it to the client), im just inserting the controls, setting values im reading from DB and then reading them (Here is where im getting hte error)(This might seem dumb, but in the function where i read the values, som calculations are done and i would like to reuse thos function the way they are)

I'm trying to use headers property of httpwebrequest to send a cookie to a server. For diong so, ii'm using add method of httpwebrequest.headers.
I can add any header included cookies. But, the problem is the cookie is not recieved by the server.
How i know that is simple. I wrote one page on server that prints request headers and cooikes. when i use my code on this page the cookie is not there (as i said before any other headers will be shown in this page az request headers).
Please somebody help.

I think u misunderstood me. I want to send cookies from client to server. cookiecontainer is an object for response to put cookies in it. without it httpwebresponse can't send cookies back to client.
