Dev gridview tips

1. Set a column in the Gridview control to be uneditable.

This. gridData. gridView1.Columns ["change_date"]. OptionsColumn. AllowEdit = false;

Field: change_date is a field in the database and is bound to the gridview.

2. Set the Gridview control to make it uneditable.

This. gridData. IsEnableEdit = false;

3. Set the Gridview control and the column headers cannot be sorted.

This. gridDataDetail. gridView1.OptionsCustomization. AllowSort = false;

4. Make the Gridview Control lose the selected focus

This. gridData. gridView1.FocusedRowHandle =-1

5. Check whether data is selected in the Gridview.

Int index = this. gridData. gridview1.getfocused#cerowindex ();

If the index is smaller than 0, it indicates that no row is selected. Otherwise, the row data is selected.

6. Obtain the row data of the selected Gridview

DataRow vCurrenRow = this. gridData. gridView1.GetFocusedDataRow ();

To convert a model object, you can operate on each line of document data separately.

ModelClass Model = vCurrenRow as ModelClass;

Model. aa = "cc ";

7. Delete the selected row of data in the Gridview.

This. gridDataDetail. gridView1.DeleteRow (this. gridDataDetail. gridView1.FocusedRowHandle );

8. Add an edit row in the Gridview.

DataRow vDetailRow = this. DataDetailSourceTable. Rows. Add (); // this is a new row.
VDetailRow ["primary_key"] = ""; primary_key is the field bound to the Gridview by the database, which can be assigned a value later.

9. obtain all the selected row numbers in the GridView.

Int [] iRowId = this. gridData. gridView1.GetSelectedRows ();
