Setting a ComboBox's Value

[Fred]

Hi,

I am having a problem setting a combobox value in code on form load using
comboBox.SelectedValue method. The code below when debugging show the
combobox equal to an undefined value. The value I am trying to set is
present the items collection. I also have tried using .SelectedItem method
and I get an object reference error. Any ideas?

comboBox.SelectedValue = comboBoxValue;

Thanks

Fred,

Have you used DataBinding with Display,Value pair to add items to the
ComboBox, in that case use SelectedValue property, otherwise use
SelectedIndex property to select a default value during load.

Hope it helps.

this.cboCollect.Items.Add("abc");

this.cboCollect.Items.Add("e");

this.cboCollect.Items.Add("g");

this.cboCollect.Items.Add("h");

cboCollect.SelectedIndex = 3;
Thanks,
Vijai
