问题描述

< pre> DataSet info1 =  this  .GetData.getInfo（  SELECT 0 AS EmpNo，Er.EmpID，（Er.FName&''& Er.LName）AS [员工姓名]，Ed.DeptNo AS [部门号]， Er.Gender AS [Sex] FROM（EmpRegist AS Er INNER JOIN EmployeeDept AS Ed ON Er.EmpId = Ed.EmpId）WHERE Ed.DeptId = +（ object ）DpetID +   AND Ed.Status = 0 AND Er.EmpStatus = 1 ORDER BY + str，  EmployeeDept）; 
  if （info1.Tables [ 0 ]。Rows.Count >   0 ）
 {
  for  （ int  index =  0 ; index <  info.Tables [ 0 ]。Rows.Count; ++ index）
  //  错误出现在下面的代码 
 此 .dgvPrint.Rows.Add（（ object ） 0 ，（ object ）（index + < span class =code-digit> 1 ），（ object ）info1.Tables [ 0 ]。行[index] [ 员工姓名]。T oString（），（ object ）info1.Tables [ 0 ]。行[index] [ 部门否]。ToString（），（ object ）info1.Tables [ 0 ]。行[index] [  EMPID]的ToString（））; 
} 
  if （ this  .dgvPrint.Rows.Count >   0 ）
 此 .btnPrint。已启用=  true ; 
  else  
  this  .btnPrint.Enabled = 假; 
 
 
} 

我的尝试：

我如何解决< blockquote class =quote>< div class =op>引用的错误：< / div>当控件是数据绑定时，无法以编程方式将行添加到DataGridView的行集合中< / blockquote>

解决方案

< blockquote>

Quote：

当控件是数据绑定时，无法以编程方式将行添加到DataGridView的行集合中

我会说它很安静......因为你现在使用网格显示一些数据源（因此数据绑定），你不能直接改变它...

你必须将行添加到数据源并刷新显示...

<pre>DataSet info1 = this.GetData.getInfo("SELECT 0 AS EmpNo,Er.EmpID,(Er.FName&''&Er.LName) AS [Employee Name], Ed.DeptNo AS [Department No],Er.Gender AS [Sex] FROM (EmpRegist AS Er INNER JOIN EmployeeDept AS Ed ON Er.EmpId = Ed.EmpId)  WHERE Ed.DeptId=" + (object)DpetID + " AND  Ed.Status=0  AND Er.EmpStatus=1 ORDER BY " + str, "EmployeeDept");
            if (info1.Tables[0].Rows.Count > 0)
            {
                for (int index = 0; index < info.Tables[0].Rows.Count; ++index)
//Error Appears on the code below
                    this.dgvPrint.Rows.Add((object)0, (object)(index + 1), (object)info1.Tables[0].Rows[index]["Employee Name"].ToString(), (object)info1.Tables[0].Rows[index]["Dept No"].ToString(), (object)info1.Tables[0].Rows[index]["EmpId"].ToString());
                        }
            if (this.dgvPrint.Rows.Count > 0)
                this.btnPrint.Enabled = true;
            else
                this.btnPrint.Enabled = false;
                        

        }

What I have tried:

How can i solve the error that says "<blockquote class="quote"><div class="op">Quote:</div>Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound</blockquote>"

解决方案

Quote:

Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound

I would say it is quiet clear... As you grid now use to display some data source (hence data-bound), you can not alter it directly...
You have to add rows to the data source and refresh the display...
