MultiColumnComboBox

[Ivan]

Hi,
Is there a way to set formatting of the Text property of the MultiColumnComboBox?

Please consider the following:

The DataSource of the MultiColumnComboBox is a DataTable with the structure:

Column1- DateTime
Column2 –DateTime

MultiColumnComboBox.DisplayMember=”Column1”;
MultiColumnComboBox.ValueMember=”Column2”;

So displayed text would be in the format “mm/dd/yyyy hh:mm:ss AM/PM”, but I want it to be displayed with the “{0:d}” format.

Thank you

Hi Ivan

The MultiColumnComboBox uses the GridListControl internally as its dropdown and we do not have a property to set any custom format for the Text
displayed in a MultiColumnComboBox.

What would be a workaround then?
Thank you

Hi Ivan The display text in the grid can be formatted using QueryCellInfo event of the GridListControl Here is a sample

Thank you for the example, but it does not solve my problem. Although the grid cells are formatted, the text of the MultiColumnComboBox is not. I don''t have a source code for the control, but I suspect that the text property is set by converting the cell value to string (ToString()).
Is there an event I can intercept, when the cell value is read, so I can pass the properly formatted string?
Thank you

Hi Ivan,

To format the text in the MultiColumnComboBox, you need not rely on grid formatting. Handling of the SelectedIndexChanged event would solve your problem.
this.multiColumnComboBox1.SelectedIndexChanged += new EventHandler(multiColumnComboBox1_SelectedIndexChanged);

private void multiColumnComboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
DateTime date = System.DateTime.Parse(this.multiColumnComboBox1.Text);
this.multiColumnComboBox1.Text = date.ToString("{0:d}");
}

Best regards,
Stanley
