BaseView.PostEditor() Method
Saves the modified cell value to the data source. If the GridOptionsView.RowAutoHeight setting is disabled, the currently active cell editor remains opened.
Namespace: DevExpress.XtraGrid.Views.Base
Assembly: DevExpress.XtraGrid.v23.2.dll
NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation
Declaration
Returns
| Type | Description |
|---|---|
| Boolean | true if the value has been successfully saved to the data source; otherwise, false. |
Remarks
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the PostEditor member must not be invoked for these Views. The PostEditor 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: Immediately update the View on cell value changes
Assume that the content or appearance settings of a View’s specific elements are dependent on cell values, and you want to update these elements immediately after a cell value is changed. For instance, you may want to calculate a custom summary or apply conditional formatting after a user changes a cell value.
To perform this task, ensure that an in-place editor (a RepositoryItem descendant) is assigned to a column. Then handle an in-place editor’s RepositoryItem.EditValueChanged event, and call a Data Grid View’s PostEditor and UpdateCurrentRow methods.
RepositoryItemTextEdit rItemTextEdit = new RepositoryItemTextEdit();
rItemTextEdit.EditValueChanged += RItemTextEdit_EditValueChanged;
gridControl1.RepositoryItems.Add(rItemTextEdit);
gridColumn1.ColumnEdit = rItemTextEdit;
private void RItemTextEdit_EditValueChanged(object sender, EventArgs e) {
if(gridView1.PostEditor())
gridView1.UpdateCurrentRow();
}
Example: Immediately save a Boolean column’s check state to a data source
To save a Boolean column’s check state to a data source once a user toggles the check box, ensure that a check edit in-place editor (RepositoryItemCheckEdit) is assigned to a column. Then handle the RepositoryItem.EditValueChanged event to call the View’s PostEditor and UpdateCurrentRow methods.
RepositoryItemCheckEdit checkEdit = new RepositoryItemCheckEdit();
checkEdit.EditValueChanged += repositoryItemCheckEdit_EditValueChanged;
gridControl1.RepositoryItems.Add(checkEdit);
gridView1.Columns["Marked"].ColumnEdit = checkEdit;
private void repositoryItemCheckEdit_EditValueChanged(object sender, EventArgs e) {
if(gridView.PostEditor()) {
gridView.UpdateCurrentRow();
}
}
