Hi,

I have added a ComboEditor in a grid cell. I want to have multiple selections, so the CheckBoxStyle is CheckStyle.CheckBox.

I have created a DataTable with DataColumns in code and assigned to grid.DataSource.

(1) For the ComboEditor, what is the type of the DataColumn?

DataColumn dc = new DataColumn ("colName", typeof (???))';

(2) How can I access the check boxes when I create the grid? In the InitializeRow event of the grid, I create a ComboEditor and assign it to grid.EditorComponent, but when I fill the combeEditor items with ValueListItems with the CheckState = CheckState.Checked, none of the check boxes are checked. Only CheckState.Indeterminate will show a gray checked checkbox.

Regards and thanks.

Hi,

I tried this out in a small sample (which I have attached here just for reference) and I get the same results.

It seems to work if the grid column DataType is object[] but not string[].

I'm going to forward this thread over to Infragistics Developer Support so they can open a case for you and have this looked into as a possible bug.

Hi Brian,

Thanks for the quick reply. It is working, except when I checked some check boxes and I change the focus to another cell, I get the following message:

I created the DataTable and DatColumns

DataTable dt = new DataTable ("dtBeeps");

dc = new DataColumn ("colLeftG1Speakers", typeof (string[]));

dt.Columns.Add (dc);

grdBeeps.DataSource = dt;

I assign a string array to the cell.Value for the items which have to be checked.

In the InitializeLayout event, I added the combo editor to the column.

speakers is of type string[]

if (cc["colLeftG1Speakers"].EditorComponent == null)

{

UltraComboEditor combo = new UltraComboEditor ();

combo.CheckedListSettings.CheckBoxStyle = Infragistics.Win.CheckStyle.CheckBox;

combo.CheckedListSettings.EditorValueSource = EditorWithComboValueSource.CheckedItems;

combo.CheckedListSettings.ItemCheckArea = ItemCheckArea.Item;

foreach (string item in speakers)

{

ValueListItem vli = new ValueListItem (item, item);

combo.Items.Add (vli);

}

cc["colLeftG1Speakers"].EditorComponent = combo;

}

Do I have to extract the checked values of the combo boxes to a string array?

Thanks again.

1) typeof(object), typeof(string), or System.Array. For example, if you wanted to provide a front end for multiple integers, you could use typeof(int[]).

2) The checkboxes are a representation of the cell's value. For example, if the column's data type was typeof(int[]), and you assigned int[]{ 1, 3, 5 } to the cell, the three items corresponding to those values would be would be checked
