使用会话更新gridview [英] gridview updation using session

问题描述

GridViewRow row = GridView1.Rows[e.RowIndex];

       if (Session["dt"] != null)
       {
           DataSet dt1 = (DataSet)Session["dt"];
           dt1.Tables[0].Rows[row.DataItemIndex][0] = ((TextBox)(row.Cells[1].Controls[0])).Text;
           dt1.Tables[0].Rows[row.DataItemIndex][1] = ((TextBox)(row.Cells[2].Controls[0])).Text;
           dt1.Tables[0].Rows[row.DataItemIndex][2] = ((TextBox)(row.Cells[3].Controls[0])).Text;
           dt1.Tables[0].Rows[row.DataItemIndex][3] = ((TextBox)(row.Cells[4].Controls[0])).Text;
           GridView1.EditIndex = -1;
           binddata();
       }

       if (Session["key"] != null)
       {
           Response.Write("hello");
           DataSet dt2 = (DataSet)Session["key"];
           dt2.Tables[0].Rows[row.DataItemIndex][0] = ((TextBox)(row.Cells[1].Controls[0])).Text;
           dt2.Tables[0].Rows[row.DataItemIndex][1] = ((TextBox)(row.Cells[2].Controls[0])).Text;
           dt2.Tables[0].Rows[row.DataItemIndex][2] = ((TextBox)(row.Cells[3].Controls[0])).Text;
           dt2.Tables[0].Rows[row.DataItemIndex][3] = ((TextBox)(row.Cells[4].Controls[0])).Text;
           GridView1.EditIndex = -1;
           binddata();
       }

我发现错误只有第一行对其他人进行了很好的更新我发现错误在session ["key"]中的位置1没有行..(session ["dt"]运行良好，它是一个空的数据集)

only the first row is updated well for others i found error There is no row at position 1 in session["key"].. (the session["dt"] is working well it is an empty dataset")

推荐答案

好吧，简单的错误指出Session["key"]的数据集只包含一行.

您需要使用DEBUGGER并查看自己存储在Session["key"];中的内容，并验证它存储的数据集包含的行数比您期望的要多，并且已为其编写了代码. (预计这里有4行)

Well, error simple states that Session["key"] has a dataset that has only one row in it.

You need to use DEBUGGER and see yourself what is stored in Session["key"]; and verify that it stored a dataset that has more that many rows as much you expect and have written code for. (Here 4 rows expected)
