如何在页面加载的第一行gridview.rowcommand [英] How to gridview.rowcommand for the first row on page load

问题描述

亲爱的

我的方案是当我在行命令下的gridview中单击链接按钮时。选择第一行并执行进一步的工作。我想在绑定网格后在页面加载时执行相同操作。如何使用asp.net在页面加载时为第一行调用row命令。



我的代码在这里

 尝试 
 {
  if （e.CommandName ==   do）
 {
 GridViewRow row =（GridViewRow）（（（LinkBut​​ton）e.CommandSource）.NamingContainer） ; 
会话[  reg_no] =（（HiddenField）row.FindControl（  hidRegNo））。值; 
  string  CS_FLAG =（（HiddenField）row.FindControl（  hid_Flag））值。 
会话[  CS_IS_HANDLE] =（（HiddenField）row.FindControl（  hid_IsHandle））。值; 
  if （CS_FLAG ==   Y ）
 {
  this  .lnk_Enlarge.Visible =  false ; 
 Panel_Disable（）; 
 lblStatus.Text =  此帐户已被锁定并已移至主管; 
 ModalPopupExtender.Show（）; 
} 
  else  
 {
会话[  Loan_acct] =（（HiddenField）row.FindControl（  hidLoanNo））值。 
会话[  Cycle_cut] =（（HiddenField）row.FindControl（  hidCycleCut））。值; 
会话[  Bucket_Code] =（（HiddenField）row.FindControl（  hidBucketCode））。值; 
会话[ 模块] =（（HiddenField）row.FindControl（  hid_Mod））。值; 
会话[ 产品] =（（HiddenField）row.FindControl（  hid_Prod））。值; 
会话[ 城市] =（（HiddenField）row.FindControl（  hid_City））。值; 
会话[  Billing_Cycle] =（（HiddenField）row.FindControl（  hid_BillingCycle））。值; 
 此 .Tabs.Visible =  true ; 
  this  .pnl_ActLog.Visible =  true ; 
 ShowFinancial（）; 
 ShowSituationSummary（）; 
 Show_PIL_Overdue（）; 
 ShowActivity（）; 
 ShowAppInfo（）; 
 ShowDelinquencyHistory（）; 
 ShowSchedule（）; 
 ShowContacts（）; 
 Show_Diary（）; 
 Load_All（）; 
 Show_Actions（）; 
 Show_DiaryNote（）; 
重置（）; 
} 
} 
 lbl_Status.Text =  ; 
} 
  catch （例外情况）
 {
  throw   new 异常（ 应用程序错误： + ex.Message）; 
} 
 

解决方案

如果你要做的就是选择第一个gridview行进行编辑页面加载，尝试在调用网格的DataBind（）方法之前设置gridview的EditIndex属性。像这样...

 GridView1.EditIndex =  0 ;

                   Reset();
               }
           }
           lbl_Status.Text = "";
       }
       catch (Exception ex)
       {
           throw new Exception("Application Error: " + ex.Message);
       }

解决方案

If all you are attempting to do is select the first gridview row for editing when the page loads, try setting the EditIndex property of the gridview before you call the grid's DataBind() method. Like so...

GridView1.EditIndex = 0;
