다음 함수를 구현하여 모든 레코드를 성공적으로 정렬하고 있습니다.검색된 레코드를 gridview에서 정렬하는 방법
private const string ASCENDING = " ASC";
private const string DESCENDING = " DESC";
public SortDirection GridViewSortDirection
{
get
{
if (ViewState["sortDirection"] == null)
ViewState["sortDirection"] = SortDirection.Ascending;
return (SortDirection)ViewState["sortDirection"];
}
set { ViewState["sortDirection"] = value; }
}
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
if (GridViewSortDirection == SortDirection.Ascending)
{
GridViewSortDirection = SortDirection.Descending;
SortGridView(sortExpression, DESCENDING);
}
else
{
GridViewSortDirection = SortDirection.Ascending;
SortGridView(sortExpression, ASCENDING);
}
}
private void SortGridView(string sortExpression, string direction)
{
// You can cache the DataTable for improving performance
DataTable dt = GetData().Tables[0];
DataView dv = new DataView(dt);
dv.Sort = sortExpression + direction;
GridView1.DataSource = dv;
GridView1.DataBind();
}
public DataSet GetData()
{
SqlConnection con = new SqlConnection("Data Source=MEHDI-PC\\SQLEXPRESS; Initial Catalog=PIMS; Integrated Security=true;");
{
using (SqlCommand cmd = new SqlCommand())
{
String sql = "select * from dbo.Documents1";
cmd.Connection = con;
cmd.CommandText = sql;
con.Open();
DataSet ds = new DataSet();
using (SqlDataAdapter adp = new SqlDataAdapter(cmd))

이 Gridview2의 검색 기록을 정렬되어 있지만 레코드를 결합 할 때, 그것은 ... 데이터베이스 테이블에서 모든 레코드를 구속력이 : 내가 신청하는 코드는 다음과 같습니다 검색된 레코드를 바인드하여 표시합니다. 내가 어디로 잘못 가고 있는지 이해할 수 없다. 어떤 도움을 많이 주시면 감사하겠습니다. 미리 감사드립니다.
SearchTable() 함수는 어디에 있습니까? 이 함수 코드를 추가 할 수 있습니까? –
@SainPradeep 신속한 답장을 보내 주셔서 감사합니다. 귀하의 검토를 위해 SearchTable()을 추가했습니다. 고맙습니다. –
디버그하여 조건에 맞는 최종 검색어를 확인하십시오. –
