ExtAspNet.GridPanel的一般用法

代码

< ext:Grid  ID ="gridEcUser"  runat ="server"  EnableCheckBoxSelect ="false"  EnableRowNumber ="true"
        Title ="用户管理"  AllowPaging ="True"  
        onpageindexchange ="gridEcUser_PageIndexChange"  PageSize ="10"  
        onrowdatabound ="gridEcUser_RowDataBound" DataKeyNames="UserId" >
         < Toolbars >
             < ext:Toolbar  ID ="Toolbar1"  runat ="server" >
                 < Items >
                     < ext:Button  ID ="btnAddEcUser"  runat ="server"  Text ="添加"  Icon ="Add" >
                     </ ext:Button >
                     < ext:ToolbarSeparator  ID ="ToolbarSeparator1"  runat ="server" >
                     </ ext:ToolbarSeparator >
                     < ext:Button  ID ="btnToHome"  runat ="server"  Text ="首页"  OnClick ="btnToHome_Click"  Icon ="House" >
                     </ ext:Button >
                 </ Items >
             </ ext:Toolbar >
         </ Toolbars >
         < Columns >
             < ext:BoundField  HeaderText ="用户ID"  Width ="50px"  Hidden ="true"  DataField ="UserId"  ColumnID ="UserId"   />
             < ext:BoundField  HeaderText ="姓名"  Width ="150px"  ExpandUnusedSpace ="True"  DataField ="FullName"  ColumnID ="FullName"   />
           < ext:BoundField  HeaderText ="登陆用户名"  Width ="150px"  DataField ="LoginName"  ColumnID ="LoginName"   />
               < ext:BoundField  HeaderText ="用户组"  Width ="150px"  ColumnID ="RolesFullName"  DataField ="RolesFullName"   />              
             < ext:CheckBoxField  HeaderText ="用户状态"  Width ="80px"  ColumnID ="IsOpen"  DataField ="IsOpen"    />
             <ext:LinkButtonField HeaderText=""  Width="60px" ColumnID="ModiUser" Text="修改"  CommandName="Modi" />
            <ext:LinkButtonField HeaderText=""  Width="60px" ColumnID="DelUser" Text="删除" CommandName="Del" ConfirmIcon="Question" ConfirmText="确认要删除用户吗？" ConfirmTitle="易彩国际" />

         </ Columns >
     </ ext:Grid >

 

C#代码：

 

// 数据绑定：

//说明：列的DataField名称要与DataTable中的字段名称一致。


DataTable UserDt  =  UserBLL.GetEcUserList();
gridEcUser.DataSource  =  UserDt;
gridEcUser.DataBind();

 

 

代码

　　　　 protected   void  gridEcUser_RowDataBound( object  sender, ExtAspNet.GridRowEventArgs e)
        {  
            DataRow Dr  =  e.DataItem  as  DataRow;
             if  (Dr  !=   null )
            {
                 bool IsOpen = Convert.ToBoolean(Dr["IsOpen"]);
                 if (IsOpen) e.Values[4] = "<img src='../Images/png-0010.png' style='width:16px;text-align:center'";
                 else e.Values[4] = "<img src='../Images/png-0012.png' style='width:16px;'";
                
            }

 

 Grid中列内容居中的方法：

< ext:BoundField  HeaderText ="姓名"  Width ="150px"  ExpandUnusedSpace ="True"  DataField ="FullName"  ColumnID ="FullName"  DataFormatString ="<div style='text-align:center;width:100%'>{0}</div>"    />

 

Grid的RowCommand事件中获得列值：

 

１：在Grid的DataKeyNames中设置行关键字，如：DataKeyNames="UserId,UserName"

２：

代码

 　　　　 protected   void  gridEcUser_RowCommand( object  sender, ExtAspNet.GridCommandEventArgs e)
        {

             if  (e.CommandName  ==   " Modi " )  // 修改
            {
                 string  DD  =  gridEcUser.DataKeys[e.RowIndex][ 0 ].ToString();
                ExtAspNet.Alert.Show(DD);
            }
             else   if  (e.CommandName  ==   " Del " ) // 删除
            {

            }
        }
