Listbox Binding

Question

Hi All,

    I am storing mutiple selected items indexes of a listbox in the database.

When I am trying to bind those indexes to the Listbox only the last indexed item is highlighting.

for (inti = 0; i < measure.Length; i++){

Measures.SelectedIndex =Convert.ToInt16(measure[i]);

}

 

measure is the array contianing the indexes. Measures is the Listbox.

measure[0]= 1, measure[1] = 4 . Only 4th index values is binding

Help me to bind all the selected indexes.

 

Thanks in Advance

Hi,

           Instead of using SelectedIndex, you need to use the SelectedItem  collection

            listBox1.ItemsSource = "1 2 3 4 5 6 7 8".Split(' ');
            listBox1.SelectedItems.Add(listBox1.Items[2]);
            listBox1.SelectedItems.Add(listBox1.Items[4]);
            listBox1.SelectedItems.Add(listBox1.Items[6]);

         I just showed an example of how to select multiple items.  So in your code you can write something like this

         for(int i=0;i<measure.Length;i++)

         {       Measure.SelectedItems.Add(Measure.Items[i]);         }

Hope it Helps

Thanks Kiran, but there is a small problem again,

measure[0] = 1

measure[1] = 4

I used the code which is given by you, it is selecting the first two values, but I need to select second and fifth items bcoz the indexes are 1 and 4.

 

Thanks,

hi ,

 i was just giving an example , so i kept it in that for loop.   You need to write it like this .

  I am assuming your Listbox name is Measures ,  and the array where you stored the selected indexes is Measure

  so Measure[0] =1 , Measure[1] =4

  You need to get Measures.Items[1] and Measures.Items[4]  , right.

  So you need to change that to

  Measures.SelectedItems.Add(  Measures.Items[Measure[i]]   );      

 Hope it Helps
