将行从GridView绑定到DataTable并在另一个GridView中显示它 [英] Bind Rows From GridView to DataTable and Display It In Another GridView

问题描述

我将从gridview中的列中找到一个值。如果该列中有行具有此值，我将这些行添加到DataTable中。然后我将它绑定到另一个gridview以显示这些行。但是，当我尝试这样做时，INT中的列不能在INT中显示出来，但只能在TEXT中显示出来。此外，只有1行被绑定到数据表并显示在另一个gridview中，如果许多行在该列中具有特定值，而不仅仅是1行，我想要很多行。



这是我使用的代码：

I am going to find a value from a column in a gridview. If there are rows that have this value in that column, I will add those rows to a DataTable. Afterwards I will bind it to another gridview to display those rows out. However, when I tried to do this, columns that are in INT cannot be displayed out in INT but can only be displayed out in TEXT. Also, only 1 row is being binded to the datatable and displayed out in another gridview, I want many rows if many rows have the particular value in that column, not just 1 row.

This is the code I used:

public void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
        {
 DataTable dt = new DataTable();
            DataRow dr;
            dt.Columns.Add(new DataColumn("DATE"));
            dt.Columns.Add(new DataColumn("CODE"));
            dt.Columns.Add(new DataColumn("PERSON_NAME"));
            dt.Columns.Add(new DataColumn("STATUS"));
            dt.Columns.Add(new DataColumn("HOBBIES"));
            dt.Columns.Add(new DataColumn("SCORE"));
            dt.Columns.Add(new DataColumn("ITEM"));
            dt.Columns.Add(new DataColumn("QUANTITY"));
            dt.Columns.Add(new DataColumn("TYPE"));
            dt.Columns.Add(new DataColumn("RATING"));
            dt.Columns.Add(new DataColumn("PRICE"));
            foreach (GridViewRow gvr in GridView1.Rows)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    if (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "STATUS")) == "Regular")
                    {
                        dr = dt.NewRow();
                        dr["DATE"] = e.Row.Cells[0].Text;
                        dr["CODE"] = e.Row.Cells[1].Text;
                        dr["PERSON_NAME"] = e.Row.Cells[2].Text;
                        dr["STATUS"] = e.Row.Cells[3].Text;
                        dr["HOBBIES"] = e.Row.Cells[4].Text;
                        dr["SCORE"] = e.Row.Cells[5].Text;
                        dr["ITEM"] = e.Row.Cells[6].Text;
                        dr["QUANTITY"] = e.Row.Cells[7].Text;
                        dr["TYPE"] = e.Row.Cells[8].Text;
                        dr["RATING"] = e.Row.Cells[9].Text;
                        dr["PRICE"] = e.Row.Cells[10].Text;
                        dt.Rows.Add(dr);
                        GridView2.DataSource = dt;
                        GridView2.DataBind();
                    }

有人可以帮我吗？非常感谢!!

Can someone please help me on this? Thanks a lot!!

推荐答案

我认为正确的版本将是

I think correct version would be

new DataColumn("STATUS", GetType(int)); 

或类似的东西（从记忆中写下来。

or something very similar (writing from memory.
