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"];

}
}
}

من سی شارپ نصب ندارم میتونی پیغام اررور رو بنویسی یا عکسشو بزاری ؟

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();

}

}
