asp.net Checbox在GridView中的应用实例分析

本文实例讲述了asp.net Checbox在GridView中的应用方法。分享给大家供大家参考，具体如下：

先看效果图：

前台代码：样式自己定义哦！

   
     
       
         
       
       
       
       <%#DataBinder.Eval(Container.DataItem,"oldName")%>
       
       
     
         
       
       
         
           
         
         
       
     
     
   
   

     
     
     
   

后台代码：

protected void HkrGridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
      TableCellCollection tcHeader = e.Row.Cells;
      tcHeader.Clear();
      //第一行表头
      tcHeader.Add(new TableHeaderCell());
      tcHeader[0].Text = "序号
No.";
      tcHeader.Add(new TableHeaderCell());
      tcHeader[1].Text = "附件名称";
      tcHeader.Add(new TableHeaderCell());
      tcHeader[2].Text = "备注";
      tcHeader.Add(new TableHeaderCell());
      tcHeader[3].Text = "选择";
    }
}
protected void HkrGridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    GridViewRow gr = e.Row;
    if (e.Row.RowIndex != -1)
    {
      e.Row.Cells[0].Text = (e.Row.RowIndex + 1).ToString();
    }
}
private void HkrGridViewBind(){
    string strSql = "SELECT keyId,newName, oldName, localHome,memo FROM aq_file_up WHERE (relaid = @relaid) AND (fjType = @fjType) AND (usestatus = 1)";
    SqlParameter[] sps = {
              new SqlParameter("@relaid",this.hdnRelaId.Value),
              new SqlParameter("@fjType",this.hdnFjType.Value)
               };
    DataTable dt = pms.SqlHelper.ExecuteDataTable(CommandType.Text, strSql, sps);
    tabGridView1.DataSource = dt;
    tabGridView1.DataBind();
}
rotected void Button1_Click(object sender, EventArgs e)
{
    CheckBoxAll.Checked = false;
    CheckBox1.Checked = false;
    for (int i = 0; i <= tabGridView1.Rows.Count - 1; i++)
    {
      CheckBox cb = (CheckBox)tabGridView1.Rows[i].FindControl("CheckBox");
      cb.Checked = false;
    }
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
   for (int i = 0; i <= tabGridView1.Rows.Count - 1; i++)
    {
      CheckBox cb = (CheckBox)tabGridView1.Rows[i].FindControl("CheckBox");
      if (cb.Checked == false)
      {
        cb.Checked = true;
      }
      else
      {
        cb.Checked = false;
      }
    }
    //CheckBox1.Checked =true;
    CheckBoxAll.Checked = false;
}
protected void CheckBoxAll_CheckedChanged(object sender, EventArgs e)
{
   for (int i = 0; i <= tabGridView1.Rows.Count - 1; i++)
    {
      CheckBox cb = (CheckBox)tabGridView1.Rows[i].FindControl("CheckBox");
      if (CheckBoxAll.Checked == true)
      {
        cb.Checked = true;
      }
      else
      {
        cb.Checked = false;
      }
    }
    CheckBox1.Checked = false;
}
