این قطعه برنامه چه مشکلی داره؟ قبل از اجرا هیچ اروری نمی ده ولی زمان اجرا در خط dv.sort["soal"] ایراد می گیره
namespace kalanjar
{
public partial class Form1 : Form
{
SqlConnection conn = new SqlConnection("Server=DANESH-PC\\SQLEXPRESS ;Database = kalanjar; trusted_connection=yes");
SqlCommand cmd = new SqlCommand();


DataTable dt = new DataTable();
DataSet ds= new DataSet ();
DataView dv = new DataView();
SqlDataAdapter da;
int tempp;
public Form1()
{
InitializeComponent();
}

private void textBox1_TextChanged(object sender, EventArgs e)
{

}

private void button1_Click(object sender, EventArgs e)
{

dv.Sort = "soal";
tempp= dv.Find(textBox1.Text.Trim());
if (tempp != -1)
{
textBox2.Text = dv[tempp]["javab"].ToString() ;
}
}

private void Form1_Load(object sender, EventArgs e)
{
conn.Open();
da = new SqlDataAdapter("select * from table1", conn);
cmd.Connection = conn;
da.Fill(ds);
dv.Table = ds.Tables["table1"];

}
}
}

در کل برای sort کردن باید به این روش عمل کنید من یه سمپل براتون میزارم :

کد:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string sqlQuery = "SELECT * from Table1" ;
SqlConnection conn = new SqlConnection (ConfigurationManager.AppSettings["ConnectionString"]);
SqlDataAdapter sda = new SqlDataAdapter(sqlQuery, conn);
DataTable dtData = new DataTable();
sda.Fill(dtData);

gvResults.DataSource = dtData.DefaultView;
gvResults.DataBind();
}
}

protected void btnFiltering_Click( object sender, EventArgs e)
{
string sqlQuery = "SELECT * from Table1";
SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
SqlDataAdapter sda = new SqlDataAdapter (sqlQuery, conn);
DataTable dtData = new DataTable ();
sda.Fill(dtData);

DataView dvData = new DataView(dtData);
dvData.RowFilter = "state = '" + txtFilter.Text.ToUpper() + "'";

gvFilter.DataSource = dvData;
gvFilter.DataBind();
}

protected void btnSorting_Click( object sender, EventArgs e)
{
string sqlQuery = "SELECT * from Table1";
SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
SqlDataAdapter sda = new SqlDataAdapter(sqlQuery, conn);
DataTable dtData = new DataTable();
sda.Fill(dtData);

DataView dvData = new DataView(dtData);
dvData.Sort = "city";

gvSort.DataSource = dvData;
gvSort.DataBind();
}
}
