I am working with Syncfusion tools, and am trying to add a ComboBoxAutoComplete control to a Windows form. I have a DataTable that I'm using as my DataSource with two columns: ID and Name. I set the DataSource, DisplayMember, and ValueMember properties like so:
ComboBox1.AutoCompleteControl.DataSource = table
ComboBox1.DisplayMember = "Name"
ComboBox1.ValueMember = "ID"
The control loads correctly, but it appears that the DisplayMember does not get applied. The control will display only the ID of the selected item. When I expand the drop-down, it displays the entire table (both columns). I tried setting the DisplayMember and ValueMember directly on the AutoCompleteControl, but those properties do not exist. Is there a different property that is used to control what text is displayed in the ComboBoxAutoComplete control?
We have prepared the simple sample in which we have assigned data table to "DataSource" property of AutoCompleteControl inside the ComboBoxAutoComplete to enable the AutoComplete features.
To display the value based on DisplayMember assigned the Data table columns to “Columns” (collection property) of AutoCompleteControl and set “MatchingColumn” value as True for which column has been set in DisplayMember.
Please check with the sample from below location.

I have a small project about datagridview and listbox in vb.net. But I don't know how can i create property table for each item which is inserted to list box.
I don't know how to describe but It's like that
I have a datagridview as property table to display and modified data, a text box and button to insert data to listbox.
When I add item "Shape1" it will create property table for"Shape1"
I fill data to property table for item "Shape1". Then save it as database.
Everytime when I click to item "shape1". It will show property table of shape1 again and I can modified and save it again.
Could you please tell me Is there any way or example to do like that.
I have a kendo grid in which I am using the roweditor function to allow user to change values of networks listed as network1, network2, network3 lets call it as gridNetwork.
I have a combobox on the same page having networks listed same as network1, network2, network3 what was there in grid. The user can select values from this combobox let us call it as comboNetwork.
Based on the selection made in the comboNetwork, the value of the selected row(s) network should also change in gridNetwork.
Any suggestions?
I have created a jsfiddle,give a try:

What you want is on-change function bound to your comboBox that will update your underlying data model that you have bound to your grid.
In that function, update the model, the refresh the grid's datasource that the model is populating.
If I setup a lookup for a field when designing a table (i.e. through the Lookup Wizard) and I set "Allow Multiple Values" to "Yes", a multi-select combobox (i.e. with check-boxes) is displayed in the relevant field in the "Datasheet" view of the table. My question is the following: Is the text-box component of a multi-select combobox control actually of any use? While a single-select combobox lets you type a new value that is not in the list or facilitates the auto-complete feature when typing a value that is included in the list, but the multi-select combo box prevents you from typing anything in its textbox, and that behavior doesn't seem to change via the properties of the combobox control.
The reason I need this feature is because I want to type there something not in the list, in order to trigger the control's NotInList event, so that I can update the corresponding lookup table with the new value I typed.
Thanks
I have a datagrid from devexpress in a winform application.I populated the datagrid from code (datasource=my datatable with 2 strings columns and one of type int (receive 0 and 1 values-should be checkbox on form).
I added a datagrid and from designer I added 3 columns.The last one of type checkbox.I set
UnboundType=Integer,
UnboundExpression=my column name from datatable :
DisplayFormat = Numeric,
columnedit = checkbox,
Displaycheckedvalue = 1,
displayuncheckedvalue = 0.
When I run the application always my checkboxes are blue.If i press one checkbox appear a check but when i go to the next row the previous value is again blue.What should i do so why the application keep the checks?
Don't set the column to be unbound, it is in your datasource after all.
What you want to do is just to set Displaycheckedvalue and displayuncheckedvalue as you have done, nothing more.
You can make a class which got a property for each column of your table. The int value would be a bool and so you can use List as datasource. The Grid will automaticly add checkboxes for the bool value.
If you want to use DataTable see Stig's post but in my opinion it is more beautiful to use classes and List.
I have an Ext.grid.EditorGriPanel which has an combobox editor in its columnModel (the store of combox has just only 2 items: enabled/disabled). When a new blank row is inserted to grid, I want the combobox in that column have to be set to a default value (enabled), and the dropdown is not expanded.
I've tried to use
grid.colModel.columns[2].editor.select(0)
to get the combobox editor and set "enabled" value for it, but it did not work. Another way is using grid.colModel.columns[2].getCellEditor(rowIndex), but it returns an EditorGrid (I was so surprised because the ExtJS 3.3.1 API doesn't have this component).
Could you please help me on this problem?
Thank you so much!
When a new blank row is inserted to
grid, I want the combobox in that
column have to be set to a default
value (enabled), and the dropdown is
not expanded.
When the new record is inserted to the grid's store, the value of your column (in the record) needs to be set to "enabled". I'm not sure if you are doing it like this currently? In other words, the value must not be set to the editor of the column. Set it directly in the record.
(Also, you can define default values to be used for all records using the recordType property of the store - see ExtJS API documentation for more details - but this is optional.)
Finally, note that the combobox will not be displayed immediately after the row is added. The combobox is displayed only when you start editing that particular cell - this is the way EditorGrid works in ExtJS. But at least you should get the new row to immediately display the correct value ("enabled") with this advice.
