如何获得按钮Id和字段名在gridview

本文关键字：gridview 字段 何获得 按钮 Id | 更新日期: 2023-09-27 18:09:08

我有一个gridview，我正在为每个列创建dynamic控件。

为例:

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

注: LB指Link Button

我在RowCreated事件

中生成如下按钮
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);
}

在click事件中是否有办法找出特定实例的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LB的第一行和第一列我想得到LB Id和name即，Country

如何获得按钮Id和字段名在gridview

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);
}

和Click Event:

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

您可能应该为网格视图添加行命令按钮。请参考此处

，您可以在RowCommand Event

中获得所有期望的值
protected void gridMembersList_RowCommand(object sender, GridViewCommandEventArgs e)
 {
     }

只需将sender对象转换为按钮类型并获取值:

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

   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");
        }
    }

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();
  }
}
