ColumnView.GetRowCellDisplayText(Int32, String) Method

Gets the display value of the specified cell.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v24.2.dll

Declaration

C#

public string GetRowCellDisplayText(
    int rowHandle,
    string fieldName
)

VB.NET

Public Function GetRowCellDisplayText(
    rowHandle As Integer,
    fieldName As String
) As String

Parameters

Name	Type	Description
rowHandle	Int32	An integer value specifying the handle of the row in which the desired cell resides. Row handles are not data source indexes, see the Accessing Rows in Code. Row Handles section of the “Rows” article for more information.
fieldName	String	A string representing the field name of the column that contains the required cell. A ArgumentNullException exception will be thrown if the current View does not contain a column with the specified field name.

Returns

Type	Description
String	A string representing the required cell’s display text.

Remarks

Use the GetRowCellDisplayText method to obtain a textual representation of a specific cell’s value. The returned string is formatted as specified by the GridColumn.DisplayFormat property of the column in which the specified cell resides. If you need to obtain the cell’s actual value use the ColumnView.GetRowCellValue method.

The GetRowCellDisplayText method returns an empty string if the specified row handle doesn’t point to any of the rows within the current View or points to a group row.

For more information on row handles refer to the Rows document.

Note

In Instant Feedback Mode, this GetRowCellDisplayText method has limitations. It returns a correct value only if the target row has been loaded. Otherwise, it returns an empty string.

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the GetRowCellDisplayText member must not be invoked for these Views. The GetRowCellDisplayText member can only be used with Views that display real data within the Grid Control. Use the following methods to access these Views with which an end user interacts at runtime.

• GridControl.MainView - returns the top most View in a grid;
• GridControl.FocusedView - returns the focused View;
• GridControl.DefaultView - returns the currently maximized View;
• the sender parameter of View specific events;
• GridView.GetDetailView - returns a detail clone View for a specific master row.

Example

The following code shows how to select rows that contain “Mexico” in the Country column and copy data from these rows.

C#

using DevExpress.XtraGrid;
using DevExpress.XtraGrid.Columns;
using DevExpress.XtraGrid.Views.Base;

ColumnView view = gridControl1.MainView as ColumnView;
GridColumn colCountry = view.Columns["Country"];
GridColumn colCompany = view.Columns["CompanyName"];
if (colCountry == null || colCompany == null) return;

// Enable multiple row selection mode.
view.OptionsSelection.MultiSelect = true;
view.ClearSelection();
int rowHandle = -1;
// Select rows that contain 'Mexico' in the Country column.
while (rowHandle != GridControl.InvalidRowHandle) {
    rowHandle = view.LocateByDisplayText(rowHandle + 1, colCountry, "Mexico");
    view.SelectRow(rowHandle);
}
int[] selectedRowHandles = view.GetSelectedRows();
if (selectedRowHandles.Length > 0) {
    // Move focus to the first selected row.
    view.FocusedRowHandle = selectedRowHandles[0];
    // Copy the selection to the clipboard
    view.CopyToClipboard();
    // Copy the selected company names to a Memo editor.
    memoEdit1.Text = "";
    for (int i = 0; i < selectedRowHandles.Length; i++)
        memoEdit1.Text += view.GetRowCellDisplayText(selectedRowHandles[i], colCompany) + "\r\n";
}

VB.NET

Imports DevExpress.XtraGrid
Imports DevExpress.XtraGrid.Columns
Imports DevExpress.XtraGrid.Views.Base

Dim view As ColumnView = CType(GridControl1.MainView, ColumnView)
Dim colCountry As GridColumn = view.Columns("Country")
Dim colCompany As GridColumn = view.Columns("CompanyName")
If colCountry Is Nothing OrElse colCompany Is Nothing Then Return
'Enable multiple row selection mode.
view.OptionsSelection.MultiSelect = True
view.ClearSelection()
Dim rowHandle As Integer = -1
'Select rows that contain 'Mexico' in the Country column.
While rowHandle <> GridControl.InvalidRowHandle
    rowHandle = view.LocateByDisplayText(rowHandle + 1, colCountry, "Mexico")
    view.SelectRow(rowHandle)
End While

Dim selectedRowHandles As Integer() = view.GetSelectedRows()

If selectedRowHandles.Length > 0 Then
    'Move focus to the first selected row.
    view.FocusedRowHandle = selectedRowHandles(0)
    'Copy the selection to the clipboard
    view.CopyToClipboard()
    'Copy the selected company names to a Memo editor.
    MemoEdit1.Text = ""
    For i As Integer = 0 To selectedRowHandles.Length - 1
        MemoEdit1.Text += view.GetRowCellDisplayText(selectedRowHandles(i), colCompany) & vbCrLf
    Next
End If
