I am aware that there other questions like this, but their solutions do not work for me. Populating the LookupEdit with the DataSource works fine, the user can select the desired PaperSize from the dropdown, and. The problem I have is setting the EditValue, it simply does nothing.
PaperSizes, including the one that is found in the foreach loop. Object o is the item I have set earlier, the PaperSize size that Ive found in the loop, but object p is null. So first, I let the loop search in the BindingSource, which I have to define explicitely now, instead of the Printersettings object.
Finally, I avoid looking up the DataRow and go for the edit value directly. Don't know what limitations. I know this is an old thread but I just got the same problem. The accepted answer is not the best practice since our goal is to get the selected object rather than the key value.
The workaround is to call lookupEdit. This solve the problem if the lookupEdit is not changed via mouse. You have to insure that the assigned value is exists in the lookupEdit's datasource, then try set the. Text property directly. Learn more.Private label sugar scrubs

NET Core Controls. NET Bootstrap Controls.Namespace : DevExpress. ValueMember is a key property that must be assigned when setting up the lookup editor. It represents the field name whose values are used to identify dropdown rows.
The field value of the row currently selected matches the editor's edit value, i. DisplayMember field for the row. Similarly, when you change the edit value, the editor locates and retrieves the record whose ValueMember field contains the new value. If the ValueMember property is set to an empty string, selecting a row from the dropdown assigns the object which represents this row to the editor's edit value.
DataSource property. For LookUpEdit editors, ValueMember can be set to a field name that may or may not exist in the data source.How to get rid of a beehive in a tree
GetNotInListValue event and retrieve values for the field yourself. If the field is found in the data source, its value is retrieved automatically. The ValueMember property must refer to a column that contains unique values. If the data source does not contain this column, you can add an unbound column to a look up editor and populate this column with unique values by handling the LookUpEdit.
GetNotInListValue event. This approach is only applicable for LookUpEdit controls. If the lookup editor's edit value is bound to a field in a data source, this field's type must match the type of the ValueMember field.

Namespace : DevExpress. A lookup editor is an editor with an embedded dropdown window, which displays lookup records the records from which an end-user can select. When a lookup record is selected, the editor's value the BaseEdit. EditValue bindable property and display text are modified accordingly. You may want to filter the popup data source of one secondary lookup editor based on the value of another primary lookup editor. This scenario is covered in the following topic:.
The following list shows some of the members that help you perform the additional customization of the LookUpEdit control. At design time, you can accomplish this by clicking the Populate Columns link in the editor's smart tag menu. See the "Repository items" section in the Editors and Simple Controls topic for more information.
TextEditStyle property automatically switches to Standard when you select either of these modes. AutoSuggest runs a custom Task to return a collection of items for the drop-down panel. As a result, the editor has a virtual data source that changes every time a user text changes.

This mode is primarily used with unbound editors. AutoSearch uses the default search logic to find required items in the data source to which this lookup is bound. AutoSuggest that runs a custom asynchronous task a System. Task object.
This task performs a search against the given data set, and returns the ICollection object with records that match the entered text.
This collection is automatically assigned to the editor's DataSource and its entries appear in the editor drop-down menu. QuerySuggestions - assign a Task that performs the search and returns the suggestions colleciton. Text - returns the currently entered user text. SetMinimumAnimationDuration - while a Task is searching for suggestions, the editor displays a loading indicator.
To prevent this indicator from flickering when the search completes too fast, the SetMinimumAnimationDuration method allows you to set the minimum on-screen duration. SetHighlightRanges - allows you manually choose which parts of found items should be highlighted.Nexys 4 ddr github
You can click the "Open Solution" Ribbon button to view the complete demo code. In this demo, suggestions drop-down menu items are retrieved on the QueryAsync task. The SetMinimumAnimationDuration method ensures the loading indicator is visible for at least one second. The code below demonstrates how this QueryAsync Task is implemented.
The EnsureAllEntries method retrieves all locations from the source. If a user opens the editor drop-down menu, all these entries are visible. Otherwise, the method compares user text with data source records. Each record also contains country and state names, country UN code, and Unicode city name. All records are extracted inside the custom Entry class.
The Entry class contains data fields for Excel file columns, plus additional data fields for values combined from standard fields. The HtmlText property decalred in the Entry class is optional - it is not required to implement the auto-suggest functionality.I did find an example for TestComplete Examplebut couldn't convert it to C.

This question involves a similar problem, but the code is drastically simplified. Still, even as simple as this example is, I can NOT get the dropdown to pre-select the correct value. That much is working, but selecting the correct value on form load will not work. However, when I set either of these during form load, nothing happens; the dropdown has a blank entry selected and the rest of the values are seen when you expand the dropdown.
I've tried each of these methods:. Edit - I posted a comment below under platon's answer, but I'll post it here as well. I eventually used a stored procedure instead to populate this dropdown, instead of an Enum. You need to set the editor's EditValue property to a value according to the type of the editor's Properties. ValueMember field type. I mean, if this is a string field, the EditValue should be set to "2", not 2 and so on. This should help. If not, please try to call the editor's Properties.
