C#: Using one Data Table in order to fill 2 different comboboxes?
- by odiseh
Hi all.
I have 2 comboboxes on a form (form1) called combobox1 and combobox2.
Each comboboxes should be filled with data stored in 2 different tables in Sql server 2005: table1 and table2
I mean: combobox1 -- table1 combobox2 -- table2
I fill data table with proper data and then bind the comboboxes to it separately.
My problem is: after filling 2 combos, both of them have equal data got from table2.
This is my code:
DataTable tb1 = new DataTable();
//Filling tb1 with data got from table1
combobox1.Items.Clear();
combobox1.DataSource = tb1;
combobox1.DisplayMember = "Name";
combobox1.ValueMember = "ID";
combobox1.SelectedIndex = -1;
//filling tb1 with data got from table2
combobox2.Items.Clear();
combobox2.DataSource = tb1;
combobox2.DisplayMember = "Name";
combobox2.ValueMember = "ID";
combobox2.SelectedIndex = -1;
What's wrong?
It seems that if I get 2 different data tables (tb1 and tb2) , every thing will be all right.
Any suggestions please.
Thank you
