I added a lot of myComboBox controls to form.
Every combobox shows all its content selected.
Selection is removed only when I tab off from the control.

How to hide selection initially?
There is not HideSelection property in Combobox.

Andrus.

class myComboBox : ComboBox {
internal myComboBox(DataRow dr, DataTable table) {
DisplayMember = "DisplayMember";
ValueMember = "ValueMember";
DataSource = lookup.GetPickList();
DataBindings.Add("SelectedValue", table,
dr["controlsrc"].ToString());
AutoCompleteSource = AutoCompleteSource.ListItems;
AutoCompleteMode = AutoCompleteMode.SuggestAppend;
}}

Set the focus on another Control.

Thank you.

I add combo boxes programmatically in a loop in UserControl constructor.
Should I set focus in constructor ?

My form creation code is:
class LayoutUserControl : UserControl {

public LayoutUserControl(Control container, int layoutNumber,

DataTable table, string formSource, char
tableType) {

container.SuspendLayout();

int tabI = 1;

foreach (DataRow dr in desktop.DataSet.Tables[0].Rows) {

Control control;

myComboBox myComboBox = new myComboBox(dr, table);

control = myComboBox;

control.TabIndex = tabI++;

elem.control = control;

container.Controls.Add(elem.control);

flds.Add(elem);

}

container.ResumeLayout();

}

Set the focus at the end of the loop.

Kevin,

thank you. I added
myComboBox.Focus();

immediately after line

container.Controls.Add(elem.control);

inside combo boxes creation loop.

However texts in all combo boxes are still selected.

What I'm doing wrong ?

I told you to (1) Set the Focus on some other Control than the ComboBox, and
(2) to do it "at the end of" the loop, meaning *after* the end of the loop.
The ComboBox is already getting the Focus. You want to put the Focus
elsewhere.

Kevin,

thank you for your patience.

I added Focus(); outside the loop, after container.ResumeLayout() line.
I also tried to add Focus(); to textbox control outside the loop.

All texts in all combo boxes are still selected in all cases.

What I'm doing wrong ?
