Telerik RadGrid에서 선택된 행 수 식별

Telerik의 RadGrid 컨트롤을 FormView와 함께 양식에서 사용하고 있습니다. RadGrid에서 행을 선택하면 선택한 행의 세부 정보가 FormView 컨트롤에 표시됩니다. 페이지에 버튼을 클릭하면 FormView의 모드가 "삽입"으로 변경되지만 RadGrid의 행이 선택된 경우에만 변경됩니다. 그렇지 않으면 레이블이 나타납니다. 불행하게도, RadGrid의 선택된 항목 수를 0 이상으로 계산할 수는 없습니다. 즉, RadGrid에서 행이 선택되어 있어도 버튼을 클릭하면 항상 레이블 텍스트가 표시됩니다. 버튼 여기Telerik RadGrid에서 선택된 행 수 식별

다음은 RadGrid 마크 업입니다 RadGrid의 선택 항목 수를 식별에 어떤 도움을 주시면 더 좋구요

if (rgAssnmtList.SelectedItems.Count > 0) 
{ 
    fvInspsDets.ChangeMode(FormViewMode.Insert); 
} 
else 
{ 
    fvInspsDetsLbl.Text = "Please select an assignment from the table at the top of the screen."; 
    fvInspsDetsLbl.ForeColor = System.Drawing.ColorTranslator.FromHtml("#CA2823"); 
}

사용 radGridView1.SelectedCells.Count 셀을 선택하려면 또는 radGridView1.SelectedRows.Count

또한 RowInfo 및 ColumnInfo 선택한 row 및 column에 액세스하는 데 사용합니다.

확인이 샘플 코드 :

this.radGridView1.MasterTemplate.BeginUpdate(); 
int count = this.radGridView1.SelectedCells.Count; 
for (int i = 0; i < count; i++) 
{ 
    GridViewRowInfo row = this.radGridView1.SelectedCells[i].RowInfo; 
    GridViewColumn column = this.radGridView1.SelectedCells[i].ColumnInfo; 

    string text = Convert.ToString(this.radGridView1.SelectedCells[i].ColumnInfo.HeaderText); 
    GridViewCellInfo cell = this.radGridView1.SelectedCells[i]; 
    double val = Convert.ToDouble(cell.Value); 
} 
this.radGridView1.MasterTemplate.EndUpdate();
