MVC :: To Perform Mathematical Operations Within A .aspx View?
Jan 14, 2011Is it possible to perform mathematical operations within a .aspx View.? for example..lets say i have a total number of pencils of say 100. and i have 12 students on a data table with his or her name, and the number of pencils she has
Student Name: Pencil #
John 10
Sarah 12
Linus 19
But while rendering the view i want to calculate the Percentage of pencils one student possesses out of the total. (John would have 10% of the total 100 pencils)
How would i just perform this basic math operation, and encode the result into the view. I know i need to store the 100, and divide by each count of pencils for each student within the foreach loop. but i keep getting 0. This seems very elementary i know.. Help would be very appreciated. Google seems to have nothing for me.
Forms Data Controls :: How To Update A Gridview Footer With A Mathematical Operation
Jan 12, 2011I have two textBox, one button and one gridview. In one texbox, I enter a value, click the button to add this entry to the gridview and the footer is computing the sum as i add more entries to the gridview.
I also have a textbox outside the gridview that will hold an amount, now I want to perform an operation like...(txtOutsideGridview - gridviewEntry1 - gridviewEntry2), and display the result of this operation inside the footer of the gridview, instead of the sum. How do I go about doing this?
So far all I have been able to do is sum up the total of entries within the Gridview, but that is not my desired operation...here is what my current code looks like

Forms Data Controls :: Using A Gridview To Perform Bulk Update?
Feb 9, 2010I have a gridview with checkboxlist for each record. I was updating each record individually based on that check, but now they want it to be a bulk update instead of individual. So i have commented out my individual update and added a button below the gridview and created my button event, how to loop thru the gridview and find the checked records and call my update procedure.
i found something kinda close to what i need, but its in VB and not sure how to convert that to C#

Forms Data Controls :: Use The Gridview To Actually Perform An INSERTand Not A True Update?
Dec 15, 2010if it's possible to use the Gridview (SQLDatasource) UpdateCommand to actually perform an INSERT and not a true update.Here's the dealUsing a Select statement in my SQLDatasource,I'm retrieving records for which there are no History records for a specified period.(Essentially, I'm asking "Show me all records for which there are no historical records within a specified range").I'm using that result set to feed my GridView. Basically, I'm displaying all I need to know about the insert records sans one piece of info.When the user choose the "Edit" button, the row goes into edit mode.Using a template field, I've created a drop down box to allow the user to input the status of the data for that particular time period.When they click the save button,the idea is that the UpdateCommand will fire.However, when I click the save button (in edit mode),I get a postback error that tells me System.Data.SqlClient.SqlException: Must declare the scalar variable "@EQP_PK".

Forms Data Controls :: Perform Calculations On Database Values Within A Details / Formview
Jun 10, 2010In a details or form view I have a number of entries from a database
For example:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage
If I want to perform a simple calculation on these values, and then display them in the same details/form view
Such as:
QBRating =((Passes-Completed/Pass-Attempts)*100)+(AvgYds*5)+(TDPercentage*4)
With the ideal result being:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage, QBRating on the same Details/Form view.
So basically I need to programmatically get at those values, perform calculations on them and them display them back in the same control.
Forms Data Controls :: Place The Textboxes In The ItemTemplate In Order To Perform Row Updates?
Nov 5, 2010I have a gridview that is inside a tabcontainer. In this gridview, I have a commandfield that shows an edit button. It also uses an ItemTemplate to display read-only data and an EditItemTemplate containing textboxes for updating rows. Clicking the "Edit"button works as it triggers the RowEditing event. In this event, I assign the new edit index and rebind the datatable to the gridview. It also displays all controls declared in the EditItemTemplate when the "Edit" button is clicked. But for some reason, when I hit the "Update" button, the RowUpdating event doesn't fire unless I set CausesValidation="false". But with this setting, I am still unable to update a row in the gridview. It seems that gridview's editindex is reset to -1 as I can't seem to find any controls in my EditItemTemplate.
When run in debug mode, I noticed that the gridview's editindex resets to -1 even before the TabContainer's ActiveTabIndexChanged is fired and that the gridview's state changes to read-only as I can only find controls in the ItemTemplate in the RowUpdating event. There's nowhere else in my code that I rebind the gridview's datasource except in the RowEditing event. I have also watched the RowCreated and RowDataBound events but they both don't do any rebinding of the data to the gridview.
I am in a point where I want to place the textboxes in the ItemTemplate in order to perform row updates as I can't find anything on the web that can lead me to solve this problem
Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?
Apr 1, 2011I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
