使用ASP.Net Gridview控件中的复选框仅打印选定的列 [英] Print only the columns which are selected using checkbox in a ASP.Net Gridview control

问题描述

我有一个gridview，其中我想为gridview的每一列放置一个复选框，我还需要打印那些已经检查过的列。我可以这样做吗？



目前我有以下代码

< asp：GridView ID =GridView2runat =serverAutoGenerateColumns =false>

<列> < asp：TemplateField HeaderText =NameSortExpression =NameControlStyle-Width =150pxItemStyle-Horizo​​ntalAlign =Left>

< HeaderTemplate>

< asp：CheckBox ID =ChkNamerunat =serverText =Name/>

< asp：Label ID =NameHeaderVisible =falserunat = serverText =NameForeColor =Black><％ - < asp：LinkBut​​ton ID =NameHeaderVisible =truerunat =serverText =ShopName + ContactPersonForeColor =Black CommandName =SortCommandArgument =Name> - ％> < / HeaderTemplate>

< itemtemplate>

< asp：Label ID =Namerunat =serverText ='<％＃bind（名称）％>'CssClass =labelwrap>



< itemstyle width =150px>

< controlstyle width =150px>

< asp：TemplateField HeaderText =FNameSortExpression =FNameControlStyle-Width =200pxItemStyle-Horizo​​ntalAlign =LeftItemStyle-CssClass = labelwrap>

< HeaderTemplate>

< asp：CheckBox ID =ChkFNamePartyrunat =serverText =FName/>

< / HeaderTemplate>

< itemtemplate>

< asp：Label ID =LNamerunat =serverText ='<％＃bind（LName）％>'CssClass =labelwrap>



< itemstyle width =150px>

< controlstyle width =150px>







protected void Button1_Click（object sender，EventArgs e）

{

StringWriter sw = new StringWriter（）;



HtmlTextWriter hw = new HtmlTextWriter（sw）;



GridView1.RenderControl（hw）;



string gridHTML = sw.ToString（）。替换（\，'）

.Replace（System.Environment.NewLine，） ;

StringBuilder sb = new StringBuilder（）;

sb.Append（< script type ='text / javascript'>）;

sb.Append（window.onload = new function（）{）;

sb.Append（var printWin = window.open（''，''，'left = 0 ）;

sb.Append（，top = 0，width = 1000，height = 600，status = 0'）;）;

sb.Append（ printWin.documen t.write（\）;

sb.Append（gridHTML）;

sb.Append（\）;）;

sb.Append（printWin.document.close（）;）;

sb.Append（printWin.focus（）;）;

sb.Append（printWin.print（）;）;

sb.Append（printWin.close（）;};）;

sb.Append（ < / script>）;

ClientScript.RegisterStartupScript（this.GetType（），GridPrint，sb.ToString（））;



}
