Items are many datarows.

I have a combobox. And i have a datagridview.
i want when click combobox it drops datarows of datagridview down.
How can i do that ! thanks

you want a dropdown datagridview?

I assume that you mean that you want the values from one of the columns in the grid to be displayed in the ComboBox. Assuming that your data is bound, you can simply bind the same data to both the grid and the ComboBox. The specify which column to display in the ComboBox using the DisplayMember property:

vb.net Code:

Me.BindingSource1.DataSource = myList
 
Me.DataGridView1.DataSource = Me.BindingSource1
 
Me.ComboBox1.DisplayMember = "SomeColumn"
Me.ComboBox1.DataSource = Me.BindingSource1

In that case 'myList' might be a DataTable or any other list you care to bind. "SomeColumn" can be the name of a DataColumn or the name of a property of the items in the list.

Thanks Jm. But i am sorry. i mean i need all rows in datagridview or another dataset will drop down when i click combox.
It means not a column as you mention , i want all columns.
i am sure it is possible. because i saw that. but i dont know
thanks. :thumb:

It is possible, but you would either have to buy it, or make it. If you want to buy it I think ComponentOne had a similar control.

If you search for multicolumn combobox you will almost certainly find some results. It's been mentioned on this forum many times before. You might also try The Code Project as I'm sure there's at least one example there.

Thanks JM.
It is thing which i need.

Is that autocomplete combobox ?

Did you read about that control? Did that information give any indication of what the control is for? Did it give any indication that it was for displaying multiple columns?
