I have a combo box in my winform. I have some items in it. I want to run the autocompelete true and fill from listitems. I am getting this property worked but i want that all the list items should be present in the combo and the whatever i type should remain at the top.
Please suggest
Thanks
to add the listbox item to the combobox you could use:
ComboBox1.Items.AddRange((From item In ListBox1.Items Select item).ToArray)

Somewhat VB beginner here.
I have a list of items in a drop down style Combo box, but instead of using autocomplete on the combo box, i want to do it in a seperate text box, and use the combo box items as the source. Please help!
First you have to setup the textbox properties. Set AutoCompleteMode to Suggest and AutocompleteSource must be set to CustomSource.
Then you have two options:
Dim items() As String = (From item As DataRowView In ComboBox1.Items Select Convert.ToString(item.Item(0))).ToArray
Dim items() As String = (From item As String In ComboBox1.Items Select item).ToArray
First line is the one to use if your combobox has a DataTable as source.
The second line is if you have manually entered items into the Combobox Item List.
Then just add this line to make sure that you get the items into the list of available items for the textbox.
TextBox2.AutoCompleteCustomSource.AddRange(items)
What i wanted is after binding combobox, the first item ( first item will be always header like 'Select Item') need to be in selected style, means the blue back color and typing will overwrite that item (autocomplete starts then).
dropdownstyle is dropdown so that user can type inside combobox.
Wanted like this
When the combobox gets focus the text will be selected automatically.
If you want the combobox to get focus right after the binding you can use
ComboBox1.DataSource = oDataSource
ComboBox1.Focus()
There are two methods :
comboBox1.Focus();
or
comboBox1.select(0, comboBox1.text.Length);
hi i have a combo box in a form which has the following values.cash sales,refund,debtor sales,debtor refund. i have added these values in the items collection.Following is the issue,the combo box during form load does not show the first value which is cash sales and which should be the default value displayed on form load.but its not showing.
I have even set the combo box style to drop down list but still its not showing.
![the combo box in form which has the mentioned issue][1]
Use this to show the default value by index:
ComboBox1.SelectedIndex = 0
Update:
Or if you cant determine the index in design time, you can use:
ComboBox1.SelectedIndex = ComboBox1.Items.IndexOf("defaultValue")
I have a continuous form where i have a listbox assigned to an ID. I cant seem to select anything in the list box. I have the row source property set to a Value List. I manually typed in "Y";"N" for the list.
If I don't assign the control source to the ID, all listboxes are selected at once on the form.
Is there any property I should change?
Thanks
You cannot sensibly use unbound controls on a continuous form.
I want to make custom combo box which have contain datagrid and textbox too.
On clicks into combo box datagridview should be appear and selecting any row particular cell value of the datagridview added on the combo.
thanks in advance..
As your question is written I have no idea how to answer it, I can't figure out how you could sensibly show a DataGridView inside a ComboBox. I'm writing this answer with the assumption that you mean that the form should have a ComboBox that are "linked" to a DataGridView rather than actually contain it.
If so, all you need to do is to add the ComboBox and DataGridView to the form, make the DataGridView invisible. Then you handle the SelectedIndexChanged event for the ComboBox, in the handler, make the grid visibile, find the index of the row and column you want to show and write code like (code not tested so might not be correct):
grid.SelectedRows.Clear()
grid.FirstDisplayedScrollingRowIndex = rowIndex
grid.Rows(rowIndex).Cells(colIndex).Selected = True
grid.Show()
