Question

我有一个gridview，我在其中为每列创建dynamic控件。

例如：

  -----------------------------------------------------------------
       Name | Column 1 | Column 2|
   ------------------------------------------------------------------
    Country |  LB      |  LB     |
            |          |         |
   -------------------------------------------------------------------
     City   |  LB      |  LB     |
            |          |         |
   -------------------------------------------------------------------

注意：LB指的是链接按钮

我在RowCreated事件

中按如下方式生成按钮

for(int i = 0; i < 4; i ++)
{
   LinkButton lb = new LinkButton();
   lb.Click += btnForTvDisplay_Click;
   lb.ID = lb + i;
   lb.Text = "Save";
   e.Row.Cells[rowIndex].Controls.Add(btnForTvDisplay);
}

点击事件有任何方法可以找出该特定实例的Name和link button Id

void lb_Click(object sender, EventArgs e)
{
    //what to do to retrieve values
}

我的意思是，如果我点击第一行和第一列的LB，我想获得LB Id和name，即国家

Answer 1

尝试：

for(int i = 0; i < 4; i ++)
{
   LinkButton lb = new LinkButton();
   lb.Click += btnForTvDisplay_Click;
   lb.ID = lb + i;
   lb.CommandName="Name";
   lb.CommandArgument=i;
   lb.Text = "Save";
   e.Row.Cells[rowIndex].Controls.Add(btnForTvDisplay);
}

在Click事件中：

void btnForTvDisplay_Click(object sender, EventArgs e)
 {
      LinkButton bt= sender as LinkButton ;
      string name=bt.CommandName;
     string id=bt.CommandArgument;
 }

Answer 2

只需将发件人对象转换为按钮类型即可获取值：

void lb_Click(object sender, EventArgs e)
 {
      Button bt= sender as Button;
      string id=bt.Id;
     string text=bt.Text;
       //get more information...
 }

Answer 3

您应该为网格视图添加一个rowcommand按钮。请参阅here

您可以在RowCommand Event

中获取所有预期值

protected void gridMembersList_RowCommand(object sender, GridViewCommandEventArgs e)

 {
     }

Answer 4

   protected void grd1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            TextBox txt = (TextBox)e.Row.FindControl("txtTaskName");
            DropDownList ddlTaskStatus = (DropDownList)e.Row.FindControl("ddlTaskStatus");
            Label lblSerialNoCat1 = (Label)e.Row.FindControl("lblSerialNoCat1");
        }
    }

Answer 5

protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
 {

 if (e.Row.RowType == DataControlRowType.DataRow)
  {

    Label lbl_ID = (Label)e.Row.FindControl("lbl_ID");
    string Id = lbl_ID.Text.Trim();
  }
}
