string s = txtqty.Text;
string k = txtproductprice.Text;

int j = Convert.ToInt32(k);
int l = i * j;
txttotalprice.Text = Convert.ToString(i);
}
--instead use
{
double i = double.parse(txtqty.Text);
double j = double.parse(txtproductprice.Text);
double l = i*j;
txttotalprice.Text = l.Tostring();
}

If you have no idea what the answer is, it's best to stay silent. Your code is not functionally different from his, and both suffer from the same basic problem.

This sort of thing gets posted EVERY day. Imagine if your page actually refreshed EVERY time you typed something ?
This event fires if you force a postback by other means. To do what you want, it needs to be done in javascript,

Why you don't use javscript for that calculation?

Here it is.
function Calculate()<br />
{<br />
document.getElementById('<%=txttotalprice.ClientID%>').value=<br />
document.getElementById('<%=txtqty.ClientID%>').value * <br />
document.getElementById('<%=txtproductprice.ClientID%>').value<br />
}

hi
you know , i think you`d better not do that like this !!! 
because ontextchanged , sends the information to the server andyour page relodes and takes so much time !
it`s better to do this on client side with java script
something like this :
var quantity = document.getElementById('txtqty').value;
var price = document.getElementById('txtproductprice').value;
document.getElementById('txttotalprice').value = quantity*price;
|
|
|
|
|
is there any other way to do this without using javascript
bcoz i dont know javascript n how to implement it... 
|
|
|
|
|
javascript is the best way 
if you have a masterpage , the way that blue boy said is better than mine 
code it like this in your .aspx page :
<script language="javascript" type="text/javascript">
the code that blue boy said
</script>
|
|
|
|
|
oh i forgot to say something else
in your code that you made textboxes you must add this function like this :
<asp:TextBox ID="textboxtotalprice" runat="server" MaxLength="20" onfocus="Function_name();"></asp:TextBox>
|
|
|
|
|
its not workin...
function Calculate()
{
document.getElementById('<%=txttotalprice.ClientID%>').value=
document.getElementById('<%=txtqty.ClientID%>').value *
document.getElementById('<%=txtproductprice.ClientID%>').value
}
<asp:textbox id="txttotalprice" runat="server"
="" ontextchanged="txttotalprice_TextChanged" autopostback="True" oninit="Calculate()">
wat to do...
|
|
|
|
|
change it to this one :
<script type="text/javascript" language="javascript">
function Calculate()
{
document.getElementById('<%=txttotalprice.ClientID%>').value=
document.getElementById('<%=txtqty.ClientID%>').value *
document.getElementById('<%=txtproductprice.ClientID%>').value
}
</script>
<asp:TextBox ID="txttotalprice" runat="server" onfocus="Calculate()">
notice that javascript is Case Sencetive !

<asp:textbox id="textbox name" runat="server"
onblur="total()">
|

hiii

oninit(),onload(),onunlload,ontextchanged(),onprerender()...exist

Dear Guys,
You People have left one thing,onblur event(given by padmanabhan) should be written to Two text boxes(txtqty and txtproductprice).In Function we have to Check whether these two TextBoxes are not null and if it is not so , Then multiply and display data in third textbox. Writing an event for third textbox is of no use here.

Hi,
I am am using commit and rollback transaction in asp.net.
due to some reasons transaction is not working.In the following code i am deleting the record and then inserting new record.If the transaction fails the transaction will be rollback.but it is not rolling back the transaction.
The following is the code:-
public static void insertdata()
{
string strfilename = "~\\Documents\\" + ViewState["MissionCat"];
string strexcelConnectionString=@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath(strfilename) + "; Extended Properties=\"Excel 8.0;HDR=YES;IMEX=1;\"";
string strsqlConnectionString = ConfigurationManager.ConnectionStrings["conn"].ToString();
using (OleDbConnection connection = new OleDbConnection(strexcelConnectionString))
{
connection.Open();
OleDbCommand command = new OleDbCommand("Select [Mission] ,[Civilian] ,[Military] ,[Police],[Unknown] ,[Non-UN] ,[Total] FROM [Sheet1$]", connection);
SqlConnection cnntrunc = new SqlConnection(strsqlConnectionString);
cnntrunc.Open();
SqlTransaction myTrans = cnntrunc.BeginTransaction();
SqlCommand truntble = new SqlCommand();
truntble.Transaction = myTrans;
truntble.Connection = cnntrunc;
try
{
using (DbDataReader dr = command.ExecuteReader())
{
truntble.CommandText = "DELETE FROM MissionCatReport";
truntble.ExecuteNonQuery();
myTrans.Commit();
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(strsqlConnectionString))
{
bulkCopy.DestinationTableName = "MissionCatReport";
bulkCopy.WriteToServer(dr);
}
}
}
catch (OleDbException ex)
{
myTrans.Rollback();
throw ex;
}
catch (InvalidOperationException ex)
{
myTrans.Rollback();
throw ex;
}
finally
{
cnntrunc.Close();
}
}
}
Can any one please tell me where i am going wrong.
