是否可以在“行命令"事件中获取数据键值 [英] is it possible to get a Datakey value in a Row Command event

问题描述

我整个上午都在为这个问题而苦苦挣扎...可能，我需要为特定的数据行提供值

这是我尝试过的代码

Hi ive been struggling all morning over this issue...it it possible, i need the value to for a particular datarow

here is the code ive tried

protected void Get_RowData(object sender, GridViewCommandEventArgs e)
    {

        //int ind = GridView1.SelectedIndex;
        //string id = GridView1.DataKeys[ind].Value.ToString();
 
        if (e.CommandName == "Modify")
        {
            GridViewRow row = (GridViewRow)((LinkButton)e.CommandSource).NamingContainer;
            int index = row.RowIndex;
            int employeeID = Convert.ToInt32(GridView1.DataKeys[index].Value);

            table1.Visible = true;
      // int index = Convert.ToInt32(e.CommandArgument);

          //  string indextest = GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Values["airid"].ToString();

            SqlConnection con = new SqlConnection(connectionString);
            con.Open();
            //SqlDataAdapter da = new SqlDataAdapter("sp_GetAir", con);

            DataSet ds2 = _ds.Copy();
           // da.Fill(ds2);
            DataTable dt = ds2.Tables[0];
            DataRow dr = dt.Rows[employeeID];
            txtairline.Text = dr["airlines"].ToString();
            txtdepcity.Text = dr["depcity"].ToString();
            txtdeptime.Text = dr["deptime"].ToString();
            txtdepdate.Text = dr["depdate"].ToString();
            txtarrvcity.Text = dr["arrvcity"].ToString();
            txtarrvtime.Text = dr["arrvtime"].ToString();
            txtarrvdate.Text = dr["arrvdate"].ToString();
                      
        }

    }

推荐答案

这是您在代码中用于获取特定行中数据键值的行.

This is the line you have used in your code to get the datakey value in particular row.

int employeeID = Convert.ToInt32(GridView1.DataKeys[index].Value);
