Forms Data Controls :: How To Update A Gridview Footer With A Mathematical Operation

Jan 12, 2011

I 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 is what my current code looks like

Data Controls :: GridView Crud Operation Outside Of GridView?

May 7, 2015

I have a simple add form on the page and below it is its gridview with edit and delete buttons. Everything works fine, but when i click on edit on a particular row/record, it changes to edit row but i want the record to be edited in the original add form (which is above the gridview).

I am able to edit a record on the gridview but i want it to be edited in the add form. Is there any particular way to do this? I came across formview concept but not sure if i am able to do that with it.

Below is the form and gridview code.

<%@ Page Title="Add User" Language="C#" AutoEventWireup="true" CodeFile="adduser.aspx.cs"
Inherits="_Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

DataSource Controls :: Gridview Insert Operation With Multi Value Listbox?

Dec 15, 2010

I am inserting mortgage loan scenarios in via GridView table. Let's say $100K loan with FICO score 700 in state of MN.

Sometimes I want to apply the same scenario to multiple states rather than Inserting one row at a time. I figured a Listbox with SelectionMode="Multiple" option would be to way to go.

Mar 7, 2010

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

Forms Data Controls :: Syntax For Passing ListView Data To SQL Input Parameters?

Dec 11, 2010

I have a ListView displaying data from Table A using a SqlDataSource.

I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure

(The scenario is much more complex but I've left out anything not relating to this exact problem).

I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.

This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":


Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.

What do I use instead of the word Description to reference this column in the Parameter?

Forms Data Controls :: Unable To Retrieve New Inputs And Syntax Error

Jul 27, 2010

I am trying to update the database with the edited data. However, it did not manage to read the edited data from the textbox. It returned the retrieve data that I have done in the Page_Load instead.

Why Can't Use C# Syntax In Inherits Attribute For A Closed Generic But CLR Syntax Is Fine

Jan 15, 2011

The following CLR syntax works fine in my aspx page:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage`1[HomePageViewModel]" %>

But this C# syntax does not:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage<HomePageViewModel>" %>

Note, I am not using ASP.NET MVC, but this works fine if using System.Web.Mvc.ViewPage<> from ASP.NET MVC.
My MyBasePage looks like this:

public class MyBasePage<TModel> : Page where TModel : class {
public TModel Model
get { return (TModel)HttpContext.Current.Items["model"]; }
