Forms Data Controls :: View Calculations - Multiply 2 Columns And Display Rate
Jan 17, 2011
I have a FormView Bound to an SQL data source. In the DATA there are 2 columns that i would like to multiply together and display there rate
<asp:TextBox ID="txtPeople" runat="server" Text='<%# Bind("People") %>'></asp:TextBox><asp:TextBox ID="txtRate" runat="server" Text='<%# Bind("Rate") %>'></asp:TextBox><asp:TextBox ID="txtTotal" runat="server" Text='<%# Bind("Rate * People") %>'></asp:TextBox>
This is just an example above but i believe it shows what i am trying to do, there is no calculated column in the database so i can not bind to that directly, and i can not just add the column to the data as its not in my permissions. So how do "Bind" the value of two columns multiplied together to a third text box?

I have write this code to create a gridview with 3 columns
DataTable dt = new DataTable();
dt = new DataTable();
dt.Columns.Add("ID", typeof(int)).AutoIncrement = true; [code]....
I would like to add in this code a textbox with the quantity.When i give the quantity i want in another textbox to have the total.
for example 2*1.5=3
How can i do that? My huge problem is that i dont know how to take the values of the 3rd column.The value 1.5 in this example.

I am developing an application using ASP.NET with C#.NET.in my application i have a gridview control and radobutton list having the values as Manufacturer and Distributor. based on the radiobutton selected value,the gridview will bindedup.
i am using SQL SERVER 2005 as backend server. in my database i have one table with columns as
1.mfropendate
2.mfrclosedate
3.mfrawarddate
4.distopendate
5.distclosedate
6.distawarddate
My gridview has 3 columns as Opendate,closedate,awarddate.
if user select the radiobutton as manufacturer,only mfropendate,mfrclosedate,mfrawarddate have to bind. and if user select the distributor the remaining 3 fields will have to bind. for that i had write a storedproc as create procedure sp_GetDraftBids as begin select mfropendate as opendate,mfrclosedate as closedate,mfrawarddate as awarddate, distopendate as opendate,distclosedate closedate,distawarddate awarddate from draftbids end GO
i.e i had taken the alias names for that fields so that i will bind the only 3 columns to grid view as opendate,closedate,awarddate.
My gridview code is
[Code]....
here i had taken the same alias names as i have to bind only 3 columns to gridview.when i run my application i am getting the records in data table with column names as opendate,closedate,awarddate,opendate1,closedate1,awarddate1.i.e it does not allow the same alias name.
for two radio button conditions i.e for manufacturer and distributor the gridview binded with opendate,closedate and awarddate columns as i had binded the gridview boundfields withat names.
but when user select the distributor radiobutton i have to bind the opendate1,closedate1 and awarddate1 to the gridview. for that should i can i change the storedproc are any other solution is there?

I have search for a long long time and could not find a solution to access to grid view's column properties. I have binded a grid view through this method, the bindGridView function will return a table with columns and rows.
The problem here is I cound not access to columns properties such as Grid_View.Columns.Count or Grid_View.Columns[0]."something". It seems like the grid_view does not have any column. But I can access to the Rows properties.
I have put this code within a (!IsPostBack) and set the AutoGenerateColumns to true?
I need to access to columns badly as I need t add additional column to the binded grid view.

I have developed my application using ASP.NET with Visual Basic. I have a table that contains 3 fields. The name of the table is "Customer" and the names of the fields are "Name", "Address", and "Amount". I have a gridview that displays these three columns. I want to summarize the value in the "Amount" column for each record and display the summarize value in the footer of the "Amount" column.
I added some code to the "ItemTemplate" and "FooterTemplate" of the template for the "Amount" field and wrote two functions One function adds the value of the "Amount" field to a variable called "TotalAmount" and the second function 'gets' the value stored in the "TotalAmount" variable.
I am not getting any error messages and all of the items are displayed in the gridview but I am not displaying anything at the bottom of the "Amount" column. What more do I need to do?
This is my code for the "Amount" template:
<asp:TemplateField
HeaderText="Amount"
SortExpression="Amount">
<EditItemTemplate>
<asp:TextBox
ID="TextBox1"
runat="server"
Text='<%# Bind("Amount") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label
ID="Label1"
runat="server"
Text='<%# Bind("Amount", "{0:c}") %>'>
<%#SumAmount(Eval("Amount")) %></asp:Label>
</ItemTemplate>
<FooterTemplate>
<%#GetTotalAmount() %></FooterTemplate>
<FooterStyle
BorderColor="Black"
BorderStyle="Solid"
/>
</asp:TemplateField>
This is the code in my .vp file
Dim TotalAmount as decimal 0.0
Function SumAmount(ByVal Amount
As
Decimal)
As
Decimal
TotalAmount = TotalAmount + TotalAmount
End
Function
Function GetTotalAmount()
As
Decimal
Return TotalAmount
End
Function

I have a gridview with the following columns: months, number of injury, expenses. my month column is a string, my number of injury column is a number and my expenses column is a number. I need to first obtain the month column as an integer and then obtain the number of injury column in my gridview. Once these columns are obtained, I want to be able to get the total number of injuries. How do I solve the problem. First obtain the month column and change it to an interger or gridview
Next obtain the injury column and then add each row in the injury column to get the total number of injuries.

(i have used time picker jquery to get time.)
how should i write the condition in sql and use that in C#

i have a grid view with all columns as TemplateFields( No BoundField). Based on certain condition i have to set Visibility of few columns false. Suppose when there is no column 'CaseList2' in the DataTable, then the second column of the grid (whose column index is 1 )should be invisible. But when the Gridview binds it gives error DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'CaseList2'
i googled it and found that
GridView1.Columns[1].Visible = false;
should work. But its not working actualy.
