纯脚本搞掂DataGrid表表头不动,表身滚动。

先看效果:

孟子以前也做过这事,不过他的方法前台后台都要弄,还是VB的(^-^),好像也不支持像我的自动生成列的DataGrid,所以还是自己动手,纯脚本搞掂,其实很简单,就几行:

      
  function ScrollDataGrid() 
        

            
var tb = document.getElementById("tbHeader"); 
            
var dg = document.getElementById("dgSearchResult"); 
             
            
if(dg!= null
            
{     
                
var dv = document.getElementById("dvBody"); 
                
var th = dg.rows[0]; 
                
for(var i = 0 ; i < th.cells.length;i++
                    th.cells[i].width 
= th.cells[i].clientWidth; 
                
var tr = th.cloneNode(true); 
                 
                
//tr.applyElement(tb); 
                tb.createTHead(); 
                
var tbh = tb.tHead; 
                tbh.appendChild(tr); 
                tr 
= tbh.rows[0]; 
                
var td = tr.insertCell(); 
                td.style.width 
= 19
                td.width 
= 19
                td.innerHTML 
= tr.cells[0].innerHTML; 
                th.style.display 
= 'none'; 
                
if(dg.scrollHeight < 300 ) 
                    dv.style.height 
= dg.scrollHeight * 1 + 2
                 
                 
            }
 
 
                
<table width="100%" border="0" id="tbHeader" cellpadding="4" cellspacing="0"> 
                                        
</table> 
                                        
<div style="OVERFLOW-Y: scroll; HEIGHT: 300px" id="dvBody"> 
                                            
<asp:datagrid id="dgSearchResult" style="BORDER-COLLAPSE: collapse" runat="server" Width="100%" CellPadding="4" DataKeyField="编号" BorderWidth="1px" BorderStyle="Solid" BorderColor="RoyalBlue" GridLines="None"> 
                                                
<SelectedItemStyle ForeColor="SlateGray"></SelectedItemStyle> 
                                                
<ItemStyle VerticalAlign="Middle"></ItemStyle> 
                                                
<HeaderStyle HorizontalAlign="Center"></HeaderStyle> 
                                                
<Columns> 
                                                    
<asp:ButtonColumn Text="选择" HeaderText="&lt;font face=webdings&gt;6&lt;/font&gt;" CommandName="Delete"> 
                                                        
<HeaderStyle Wrap="False" Width="40px"></HeaderStyle> 
                                                        
<ItemStyle Wrap="False" HorizontalAlign="Center"></ItemStyle> 
                                                        
<FooterStyle Wrap="False"></FooterStyle> 
                                                    
</asp:ButtonColumn> 
                                                
</Columns> 
                                            
</asp:datagrid></div>
