Dev GridControl common properties of GridView,

1. Hide the top GroupPanel:

GridView1.OptionsView. ShowGroupPanel = false;

2. Obtain the value of a field in the selected record:

SValue = Table. Rows [gridView1.FocusedRowHandle] [FieldName]. ToString ();

3. data read-only:

GridView1.OptionsBehavior. Editable = false;

4. MasterDetailView not displayed:

OptionsColumn. ReadOnly = True

Editable:

8. settings of the template column:

In Columns, find ColumnEdit in its attributes.

Taking LookUpEdit as an example:

First, add LookUpEdit from the menu In-Place Editor Repository on the left of Designer. name Re1. then. add three Columns to the Columns attribute. caption is sequential: number, name, and gender. fieldnames are FID, FNAME, and FSEX in sequence. set NullText of Re1 to null.

AutoSearchColumnIndex attribute is set to 2. ImmediatePopup attribute is set to True.

Set SearchMode to OnlyInPopup.

Then, attach this template column to column 1 as mentioned above (that is, set ColumnEdit attribute of Column 1 to Re1)

Finally, we need to bind the data source and display item to Re1 in the code.

Re1.DataSource = DALUse. Query ("select fid, fname, fsex from dual"). Tables [0];

Re1.DisplayMember = "FSEX ";

Re1.ValueMember = "FNAME ";

GridView1.Columns [0]. AppearanceCell. TextOptions. HAlignment = DevExpress. Utils. horzarignment. Center;

GridView1.Columns [0]. OptionsFilter. AllowAutoFilter = false;

GridView1.Columns [0]. OptionsFilter. AllowFilter = false;

GridView1.Columns [0]. OptionsFilter. ImmediateUpdateAutoFilter = false;

11. Set freeze columns (left frozen ):

GridView1.Columns [0]. Fixed = DevExpress. XtraGrid. Columns. FixedStyle. Left;

12. Get the cell data (0 rows and 0 columns ):

String ss = gridView1.GetRowCellDisplayText (0, gridView1.Columns [0]);

String ss = gridView1.GetRowCellValue (0, gridView1.Columns [0]);

13. Set cell data:

GridView1.SetRowCellValue (0, gridView1.Columns [0], "123 ");

14. To set the automatically added row number, add the mdrawrowindicator event to the gridview first.

Private void gridview_CustomDrawRowIndicator (object sender, DevExpress. XtraGrid. Views. Grid. RowIndicatorCustomDrawEventArgs e)

{

If (e. Info. IsRowIndicator & e. RowHandle> = 0)

E. Info. DisplayText = (e. RowHandle + 1). ToString ();
