在Gridview中显示空行 [英] Show Empty Rows in Gridview

问题描述

我的aspx页面中有一个gridview，其中包含很少的tamplate字段（TextBox）列。我希望用户在运行时输入那些临时字段。如何实现它？

< asp：GridView ID =   gridViewExp runat =   server AutoGenerateColumns =   False ShowHeaderWhenEmpty =   true >  
 
< asp：TemplateField HeaderText =   截止日期 >  
 
< asp：TextBox ID =   txtDueDate runat =   server >  
< asp：CalendarExtender ID =   CalendarExtender2运行at =   server TargetControlID =   txtDueDate格式=   dd / MM / yyyy >  
 
 
< asp：TemplateField HeaderText =  描述 >  
 
< asp：TextBox ID =   txtDesc runat =   server TextMode =   MultiLine >  
 
 
< asp：TemplateField HeaderText =  费用类型 < span class =code-keyword>>  
 
< asp：TextBox ID =   txtChargeType runat =   server >  
 
 
< asp：TemplateField HeaderText =  到期金额（INR） >  
 
< asp：TextBox ID =   txtAmtDue runat =  服务器 >  
 
 
 
< asp：TemplateField HeaderText =   Tax >  
 
 < asp：TextBox ID =   txtTax runat =    server >  
 
 
< ; asp：TemplateField HeaderText =  收到的金额（INR） >  
 
< asp：TextBox ID =   txtAmtRecv runat =   server >  
 
 
< asp：TemplateField HeaderText =   Net Payble（INR） ） >  
 
< asp：TextBox ID =   txtNetPayble runat =   server >  
 
 
 
< asp：TemplateField> 
 
< asp：按钮ID =   btnAddNewRow runat =   server CssClass =  按钮 Text =  添加新行 /> 

提前谢谢

解决方案

为此您必须添加动态具有gridview绑定的表，因为当SP或查询不返回任何值时，将不显示gridview。这就是为什么你必须创建动态表来显示gridview。



请在页面加载事件上添加代码





string name =Name;



DataTable dt = new DataTable（）;



DataColumn dc = new DataColumn（name，typeof（System.String））;

dt.Columns.Add（dc）;



DataRow dr = dt.NewRow（）;

dr [name] =No Record;

dt.Rows.Add（dr）;



GridView1.DataSource = dt;

GridView1.DataBind（）

解决方案

For that you have to add dynamic table with gridview binding because when SP or query not return any value then gridview would be not display. So that's why you have to create dynamic table to show gridview.

Please add code on page load event


string name = "Name";

DataTable dt = new DataTable();

DataColumn dc = new DataColumn(name,typeof(System.String));
dt.Columns.Add(dc);

DataRow dr = dt.NewRow();
dr[name] = "No Record";
dt.Rows.Add(dr);

GridView1.DataSource = dt;
GridView1.DataBind()

Try the following links, you may get some idea.
