Hi Folks,

I have small question regarding lists.

C#

private void ComboBox_SelectedValueChanged(object sender, EventArgs e)
       {
           
               if (dataSourceNameComboBox.SelectedItem != null)
               {
                 
                   int dataval = Convert.ToInt32(datatypeComboBox.SelectedIndex);
                   Model.ContProduct.Id= dataval ;
                   Model.Contlist.ToList<>();

                  
               }
           
       }


----- Here I want to pass 'dataval' value to the  Model.Contlist.ToList<>(); list to filter the data-----

BLL:

 public List<ContlistViewModel> Contlist{ get; set; }

DAL:

public class ContlistViewModel
{
        public int Id { get; set; }
        public string Name{ get; set; }
        public string Description{ get; set; }
        
}

Not clear. What is the integer value you need to pass, what does it represent? Why passing it is a problem?

Actually on change event of combobox list I want to display the data. So, I am getting selected index of the combo box and then I am passing it to the list. Then as already list is filled with the data and we are passing filter value as selected index, we will get the data based on the combo box.
If not can you please suggest me some method based on the current data available.
Thanks in advance!!

I'm not entirely sure what you mean by "pass 'dataval' value to the Model.Contlist.ToList<>(); list" - but I'm guessing it means "I want to use this as an index"

Why are you converting an integer value to an integer?
So try:

C#

private void ComboBox_SelectedValueChanged(object sender, EventArgs e)
       {
               if (dataSourceNameComboBox.SelectedItem != null)
               {
                   int dataval = Convert.ToInt32(datatypeComboBox.SelectedIndex);
                   Model.ContProduct.Id= dataval ;
                   ContListViewModel cvm = Model.Contlist[dataval];
                   ...                    
               }
       }

But to be honest, I'd probably load the Comboxbox with the ContlistViewModel items directly, and use the SelectedItem property instead, overriding ToString in the class as necessary.
