Simply get the id of selected item from the listbox control  by this line
int id  = listboxcontrolid.Selected.Value;

Only make sure at the time of binding listbox you should bind Value field with id column than you will get id by above pice of code.

hope this help you

Use JQuery

 <select name="List_0" size="4" id="List_0" multiple="multiple">
        <option value="Komal ">Komal </option>
        <option value="Ranjeet">Ranjeet</option>
        <option value="Vishal ">Vishal </option>
        <option value="Gaurav">Gaurav</option>
        <option value="Dhanpat">Dhanpat</option>
    </select>
    <input type="button" id="btnSelectedItems" value="Selected Items" />
Here is the jquery script:


$('#btnSelectedItems').click(function() {
                alert($('#List_0').val());
            });

Hi

Try this

The code below is from the code behind and it allows you to get multiple selected values from the listbox and pass it to the string variable called DriveWheels. 


string DriveWheels = string.Empty;
 
 for (int i = 0; i <= LstDriveWheels.Items.Count – 1; i++)
   {
    if (LstDriveWheels.Items[i].Selected && LstDriveWheels.Items[i].Value != “-1?)
     {
      DriveWheels += LstDriveWheels.Items[i].Value + “,”;
     }
   }

hi,

Try below code:

private void getId()
{
    age.categories.ToList().ForEach((c) => listcategories.Items.Add(c));
    listcategories.SelectedIndexChanged += (sender, e) => {
      Category category = (Category)listcategories.SelectedItem;
      // Do something with category.Id
    }
}
