这两天做OA时用到GridView显示数据。为了提高用户体验。想写一个单机行的事件。结果发现GridView竟然没有这个事件只好求助百度大神了。

最终终于找到了解决办法。好了废话不多说了。贴上代码

首先在前台设置一个隐藏的ButtonField

<Columns>
                    <asp:ButtonField Visible="False" Text="SingleClick" CommandName="SingleClick" />
</Columns>

然后在RowDataBound和RowCommand事件里写上这些代码。

 protected void gvRoleInfos_RowDataBound(object sender, GridViewRowEventArgs e)
    {
if (e.Row.RowType == DataControlRowType.DataRow) 
        {
            LinkButton _singleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];
string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");
            e.Row.Attributes["onclick"] = _jsSingle;



        }
    }






protected void gvRoleInfos_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        GridView _gridview = sender as GridView;
int _selectIndex = int.Parse(e.CommandArgument.ToString());
string _commandName = e.CommandName;
if (_commandName == "SingleClick") 
        {
            _gridview.SelectedIndex = _selectIndex;
        }

    }

然后在本页面重写Render方法

  protected override void Render(HtmlTextWriter writer)
    {
foreach (GridViewRow row in gvRoleInfos.Rows) 
        {
if (row.RowType == DataControlRowType.DataRow) 
            {
                Page.ClientScript.RegisterForEventValidation(row.UniqueID + "$ct100");
                Page.ClientScript.RegisterForEventValidation(row.UniqueID + "$ct101");
                Page.ClientScript.RegisterForEventValidation(row.UniqueID + "$ct102");
            }
        }
base.Render(writer);
    }
