Forms Data Controls :: Perform Calculations On Database Values Within A Details / Formview

Jun 10, 2010

In 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 :: FormView Loses New Values On Error?

Feb 3, 2011

The new values entered by a user are lost when a error occurs.

I tried to solve this by catching the error in the item updated event as per the code below

[Code]....

however the data in the form gets set back to the original values.

It seams as though the object data source is rebinding the form. How can i determine if this is the case? Is there a way to stop the datasource from rebining?

Forms Data Controls :: Formview Update Mode Not Capturing Control Values?

Jul 22, 2010

I've been spending two days on this. My page formview is in a tab container and I need it to update, insert and display data. Insert and display are ok as long as the default mode is Insert. The problem here is edit mode, it's able to get values from the db(oracle) and display them in edit mode, but when I click save, any values I typed out on the textboxes do not get captured. When I call on my db update class, it just sends old db values. Here is the process: formview shows data selected from gridview, then an update button is clicked to edit the data. there is also a SAVE button to send updated data to db. Example: description textbox = "test", then I type out a different value, and in debug mode, the textbox.text still shows "test" after clicking save.

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='<%#&nbsp;Bind("People")&nbsp;%>'></asp:TextBox><asp:TextBox ID="txtRate" runat="server" Text='<%#&nbsp;Bind("Rate")&nbsp;%>'></asp:TextBox><asp:TextBox ID="txtTotal" runat="server" Text='<%#&nbsp;Bind("Rate * People")&nbsp;%>'></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?

Forms Data Controls :: Populating Formview Fields Using Database?

Feb 1, 2010

I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.

Right now I have a datasource populating the formview via the wizard, not sure what to do next.
