DropDownGrid as standalone....

[Administrator]

Is there a way to use your DropDownGrid as a standalone control, without it being part of a gridcontrol? I''d like to use your DropDownGrid as a combo-box on a form in my app''s gui....

Thanks.

Hi,

The DropDownGrid CellType cannot be used as a standalone control. It is the GridRecordNavigationControl that holds the same parent control for easy editing and viewing. This is used only as a cell type for the Syncfusion''s grid.

I think I found what I need instead...
A MultiColumnComboBox. Where can I find documentation on this control?

How do I populate it?

Can it be populated virtually?

thx

Hi,

MultiColumnComboBox has a GridListControl in the ListBox. That can be populated through the DataSource property and can not be populated virtually. To handle the grid events you will have to use multiColumnComboBox1.ListBox.Grid.

I was able to code on the grid QueryColWidth, QueryColCount, QueryCellInfo, and QueryRowCount events.

The problem I am now facing is that I can only view 1 row of the grid at a time when I click the drop down button. What do I need to do to see more of the grid on the drop down click?

Thanks.

Two more issues:
1- There is never a value in the textbox of the combo, even when I select a row.
2- When I do click in the one row I can see, neither the SelectedIndexChanged nor the Grid.SelectionChanged event is fired.

Hi, 1- The Properties DisplayMember and ValueMember are to be used. 2- The events are triggered without fail. Here is a sample. Let me know if you find any issues. Best regards, Stanley

Thanks.

How about my issue of only 1 row showing at a time in the grid when I click the drop down?

You''ll see the question if you read the thread above the one you anwsered.

Hi,
