GridView选择行 删除行问题
对GridView数据操作,我实现的功能是单击行,把这行的数据显示到几个文本框,同时行的底色也变掉;单击行最后的ImageButton按钮,删除这行。
现在问题是,我选择行,显示数据和颜色功能没什么问题,但是每次都要点
击2次ImageButton才能删除行,第一次点击它执行的还是SelectedIndexChanging的代码。
代码如下:
(发现去掉QuestionListRowDataBound中的代码就能点一次删除行了,但是这样的话当我单击行显示数据和行颜色功能就不起作用了)

protected void c_Question_GridView_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
  {
  DisplayRowData(GetCurrentRowData(e.NewSelectedIndex), parameters);
  }

protected void c_Question_GridView_RowDataBound(object sender, GridViewRowEventArgs e)
  {
   
  if (e.Row.RowType == DataControlRowType.DataRow &&
  (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate))
  {
  e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(
  e.Row.Cells[0].Controls[1], string.Empty));
  //e.Row.Cells[0].Controls[1]是LinkButton:id='c_LblQuestion' 
   
  }
  }

protected void c_Question_GridView_RowDeleting(object sender, GridViewDeleteEventArgs e)
  {
  GridViewRowDeleting(parameters,e.RowIndex);
  }
