Manually coding controls such as gridview, listview, repeater, etc.

Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net

using vs2010 and .net 4

In my project I have a separate DAL built from class files that I'd like to use to store my code for CRUD operations against my database.

I'm having a hard time finding examples of how to code server controls like the gridview, listview, repeater etc., for CRUD operations manually, i.e., without a datasource control of some flavor.

I don't have any problem manually coding the referenced controls to get my data, but I do have problems when it comes to coding them to perform CRUD operations unless I use a datasource control. When I use the datasource controls CRUD operations seem to automagically appear out of nowhere after they're configured.

Can someone point me to some samples somewhere? Have I missed a section at MSDN?

Accessing the different controls inside a GridView control

how we can access a particular control which resides inside a GridView control. In this article I will show you how you can access different controls inside a GridView control. We will see how we can access a TextBox control, a DropDownList control and a ListBox control. If you are working with ASP.NET 1.X then you might want to check out my article Accessing Different Controls Inside a DataGrid.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

How to bind GridView and DropDownList controls using DataTable object

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

Cutting Edge: Data Repeater Controls in ASP.NET


The ASP. NET Repeater is a basic container control that allows you to create custom lists from any data available to the page. It's a handy control, especially since most ASP. NET pages that display data need to repeat the same kinds of data over and over.

how to apply validation controls on Gridview which is created dynamically

I am giving column names for this grid from some other .aspx page by passing column names using querystring.Because i am using this grid for three different pairs of column names.  i would like to know how to apply Required Field Validator, Regular Expression Validator  and Range Validator on Gridview textboxes. So that by using those validators i want to validate user inputs. And i would also like to know how to add rows at runtime for this grid. I am using ASP.net 2.0 and C#.net for this.(Visual Studio 2005) The code i am using to create gridview is below. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="LoadData.aspx.cs" Inherits="LoadData" %>  <form id="form1" runat="server">  <div> <asp:GridView ID="GrdDynamic" runat="server" AutoGenerateColumns="False" ForeColor="#333333" BorderColor="GradientInactiveCaption" BorderStyle="Solid" style="z-index: 108; left: 24px; position: absolute; top: 13px">  <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />  <RowStyle BackColor="#EFF3FB"

Editmode on GridView inside of ListView

I have a listview and inside the listview I have a gridview.  I'm binding data to the listview, then on the listview itemdatabound I'm binding the gridview. I want to make the gridview editable so I have an edit template and an edit command button.  I have the event rowediting and inside there I set the edit index. Now normally I rebind the control and everything works.  But if I rebind this gridview, nothing happens. I can trace through the rowediting and everything is working.  It's setting the edit index, it goes through the databind and gets the right data and binds it to the control. What is happening?  Why isn't my rebound edit mode gridview showing up?

Using FileUpload and GridView controls

Hi to all,I have four controls in my page: FileUpload, LinkButton, GridView, and Button.FileUpload - I use the control to browse and open an Excel file in the client machine.LinkButton - I use the control to trigger the method that copies the Excel file to the server, converts the data of Excel file to DataTable, deletes the Excel file, and returns the DataTable.GridView - I use the control to display the data.Button - I use the control to save the data to the database.I did not see any problem until I uploaded the third file that hanged my page. I noticed that every time I upload a file, the page become slower gradually.Each Excel file has 2,000 records, and every time the GridView displays an item, it searches the data on the database. I think, the more the data in the database, the slower the searches can be.To solve this problem, I set the AllowPaging property of GridView to true. The less displaying of items, the less searching of data can be. But, every time I change the page of GridView, I have to bind again the data to the GridView. In order to bind the data, FileUpload must contain the source file, but not because FileUpload frees the file when the page posts back. And I don't want the user browses the file every time he changes the page of GridView. That is very tedious.Does anyone have encountered this kind of problem? Please share us your solution.Your responses

Datalist, Gridview or Listview

I am extremely new to ASP and just started learning. I want to know which is better between Datalist, Gridview or Listview if I need paging and sorting functionality? This is what I have so far.I've tried Datalist but I am having trouble with the paging portion. I've tried gridview and listview and got the paging to work but for some reason, when I click on Pg 2, it refreshes the search or something and what was shown on Pg 1 would appear again on Pg 2.Thanks in advance for your help.<asp:MultiView id="MultiView1" ActiveViewIndex="0" Runat="server">                        <asp:View ID="View1" runat="server">                        <asp:DataList ID="DataList1" runat="server" DataKeyField="ItemID"                         DataSourceID="SqlDataSourceImage1" Width="100%"                         HorizontalAlign=

disable autopostback of checkbox inside of GridView during SelectedIndexChanged of ListView

Hi, I hope my question is clear: I have a checkbox placed inside a gridview: <GridView><asp:TemplateField HeaderText="Driver">   <ItemTemplate>       <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' />   </ItemTemplate>       </GridView> For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked. Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired. How could I disable the autopostback of the checkbox during the listview item changed. Thanks in advance
