ExtAspNet.GridPanel的一般用法

<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();

 

 

　　　　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：

 　　　　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
            {

            }
        }
