HTML CONTROL


HTML Controls are HTML elements exposed to the server so you can program against them. HTML controls expose an object model that maps very closely to the HTML elements that they render.
HTML Anchor Control
It allows programmatic access to the HTML <a> element on the server. There are two ways to use the HtmlAnchor class. The first is for navigation: using the HRefproperty to define the location of the page to link to. The second is for postback events: using the ServerClick event to programmatically handle the user’s clicking a link.
<html xmlns="http://www.w3.org/1999/xhtml" >
<script runat="server">
    Protected Sub Page_Load(ByVal sender As Object,ByVal e As EventArgs) _
Handles Me.Load
        anchor1.HRef = "/QuickStart"
    End Sub
    </script>
<head runat="server">
    <title></title>
</head>
<body>
     <h3><font face="Verdana">Simple HTML Anchor Sample</font></h3>
    <form id="form1" runat="server">
    <div>
       <p><a id="anchor1" runat="server">Go To Quick Start</a></p>
    </div>
    </form>
</body>
</html>

HTML Button Control
It allows programmatic access to the HTML <button> tag on the server. The <button> element allows Web developers to create user interface (UI) form buttons that can be composed of embedded HTML elements, including other server controls.
<html xmlns="http://www.w3.org/1999/xhtml" >
<script runat="server">
    Protected Sub btnSample_Click(ByVal sender As Object, _
ByVal e As EventArgs)
        Span1.InnerHtml = "You clicked btnSample"
    End Sub
    Protected Sub btnSample2_Click(ByVal sender As Object,
ByVal e As EventArgs)
        Span1.InnerHtml = "You clicked btnSample2"
    End Sub
    </script>
<head runat="server">
    <title></title>
</head>
<body>
    <h3><font face="Verdana">HTMLButton Sample</font></h3>
    <form id="form1" runat="server">
    <div>
        <p>
        <button id="btnSample" onserverclick="btnSample_Click" runat="server"
                style="font:8pt verdana;background-color:Green;border-
color:Black;height=30;width=100">
                <img src="Chrysanthemum.jpg" height="20" width="50"/>
                        Click Me
        </button>
                &nbsp;With embedded image
          </p>
        <p>
        <button id="btnSample2" onserverclick="btnSample2_Click"
                 runat="server"
             style="font:8pt verdana;background-color:Green;border-
color:Black;height:30;width:100"
            onmouseover="this.style.backgroundColor='yellow'"
            onmouseout="this.style.backgroundColor='Green'">
 
            Click Me too!
         </button>
            &nbsp;With rollover effect
 
        </p>
        <span id="Span1" runat="server"></span>
    </div>
    </form>
</body>
</html>


HTMLGeneric Control
HtmlGenericControl provides a server control implementation for all unknown HTML Server control tags not directly represented by a specific HTML server control (examples <span>, <div>, <body> etc).
<html xmlns="http://www.w3.org/1999/xhtml" >
<script runat="server">
    Protected Sub SubmitBtn_Click(ByVal sender As Object, _
                    ByVal e As EventArgs)
        Body.Attributes("bgcolor") = selectColor.Value
    End Sub
 
    </script>
<head runat="server">
    <title></title>
</head>
<body id="Body" runat="server">
    <h3><font face="Verdana">HTMLGenericControl Sample</font></h3>
    <form id="form1" runat="server">
    <div>
        <p>
            Select a background color the page:
            <select id="selectColor" runat="server">
                <option>White</option>
                <option>Wheat</option>
                <option>Green</option>
                <option>Red</option>
            </select>
        </p>
        <input type="submit" runat="server" value="Apply"
onserverclick="SubmitBtn_Click" />
    </div>
    </form>
</body>
</html>



HTMLImage Control
An HTML Image server control renders the image file specified by its SRC property in an HTML <img> tag.
<html xmlns="http://www.w3.org/1999/xhtml" >
<script runat="server">
    Protected Sub SubmitBtn_Click(ByVal sender As Object, _
                                  ByVal e As EventArgs)
        image1.Src = selectCereal.Value
    End Sub
    </script>
<head runat="server">
    <title></title>
</head>
<body>
    <h3><font face="Verdana">HTMLButton Sample</font></h3>
    <form id="form1" runat="server">
    <div>
        <img id="image1" runat="server" src="Grains.jpg" />
        <p>
            <select id="selectCereal" runat="server">
                <option value="Grains.jpg">Healthy Grains</option>
                <option value="cornflake.jpg">Corn Flake Cereal</option>
                <option value="honeyoat.jpg">Honey Oats</option>
            </select>
            <input id="Submit1" type="submit" runat="server" value="Apply"
                onserverclick="SubmitBtn_Click" />
        </p>
    </div>
    </form>
</body>
</html>


HTML Select Control
The HTMLSelect control provides a dropdown list. This sample illustrates using the HtmlSelect HTML control.
<html xmlns="http://www.w3.org/1999/xhtml" >
<script runat="server">
    Protected Sub Apply_Click(ByVal sender As Object, _
                              ByVal e As EventArgs)
        span1.Style("background-color") = selectColor.Value
    End Sub
    Protected Sub AddToList_Click(ByVal sender As Object, _
                                  ByVal e As EventArgs)
        selectColor.Items.Add(text1.Value)
    End Sub
 
    </script>
<head runat="server">
    <title></title>
</head>
<body>
    <h3><font face="Verdana">Simple HTMLSelect Sample</font></h3>
    <form id="form2" runat="server">
    <div>
        Select a color <br />
            <select id="selectColor" runat="server">
                <option>Blue</option>
                <option>Green</option>
                <option>Lemon</option>
            </select>
            <input id="Submit1" type="submit" runat="server" value="Apply"
                            onserverclick="Apply_Click" />
        <p>
        Don't see your color in the list above <br />
        <input id="text1" type="text" runat="server"/>
        <input id="button1" type="submit" runat="server" value="Add to List"
                            onserverclick="AddToList_Click" />
        </p>
        <span id="span1" runat="server">
            Click the button to apply a background color to this span
        </span>
    </div>
    </form>
</body>
</html>

GRIDVIEW GROUPING

When displaying data, we sometimes would like to group data for better user experience or when displaying long list of hierarchal data, we would want to display them in a tree view kind of structure. There is more than way of doing this, but I am going to explain achieving this functionality using  AJAX Collapsible Panel Extender Control .
