Development of three tabular data methods in asp.net sites

Asp.net| Data | site

In the development of ASP.net site projects, data is often displayed in tabular format. The most common possibility is the way the DataGrid binds DataSet data. Of the software projects that have been done, there are 3 typical ways of handling tabular data.

1, DataGrid binding data source. This way everyone uses the most, but the DataGrid and ado.net perfect binding way, or unpleasant. Exclusively's DataGrid style is difficult to adapt to the special styles of different projects, and personalization in the DataGrid can be very troublesome.

2, with XML (data) +xsl (style sheet). As you can see, the dataset binding to the DataGrid is a very good mechanism to implement. As shown in the illustration, the implementation of such a table, developers can enjoy the design of the XSL style.

3. Draw the data directly to the HTML. This way some soil, but sometimes very effective, first look at the implementation of the Code. The following code implements the table shown in the previous illustration.

1<table style= "width:100%; Border-collapse:collapse; height:10px ">
2 <tr>
3 <td align= "center" >
4 <table id= "Tblcontainer" class= "msonormaltable" style= "width:380px"; Border-collapse:collapse; height:10px "
5 cellspacing= "0" cellpadding= "6" border= "1" runat= "Server" bordercolor= "#99cccc" >
6 <tr>
7 &LT;TD colspan= "2" align= "Center" >
8 <p><font size= "3" ><strong><font face= "song body" > General Management Department Personnel &LT;/F Ont></strong></font></p>
9 </td>
Ten </tr>
<tr>
&LT;TD align= "center" bgcolor= "#003399" ><font size= "2" color= "#ffffff" >< strong> Person Name </STRONG></FONT></td>
&LT;TD align= "center" bgcolor= "#003399" ><font size= "2" color= "#ffffff" >< Strong> Department Position </STRONG></FONT></td>
</tr>
</TABLE>
</td>
</tr>
</table>

Add the label to the cell in the HTML directly using the Add method of ASP.net WebControls.

if (request.querystring["Audititemid"]!= null)

In the drawing of the page, in which way should be different from the beholder. In the site development, these 3 ways have a typical application, especially the third one, I found in the solution of some of the page processing performance problems in the application is very effective. In addition to automating layout page controls, personalization is much easier than rewriting render in a DataGrid.
