  I have datatable with 3 columns (ID, Name, Description) bound to C1Multiselect. How to get IDs of all selected values in C1Multiselect control. Combobox have DataMember and you can cast data as DataRow. How to accomplish the same in C1Multiselect control?

  Thank You.

  Regards

  Hello,

  You can fetch the IDs of all the selected items in C1MultiSelect by using the C1CheckListSelectedItemCollection class. Also, the DataRow corresponding to the same can be obtained using the Select method corresponding to the DataTable and using the fetched ID as the FilterExpression.
  
  Please refer the attached sample for the implementation of the same.
  
  Let us know if you need further assistance.

  Thanks,

  Hello,
  
  That doesn’t do what I expected. In your example, in combobox I want to see Names (DisplayMembetPath = Name) and after I select multiple choices in combobox, I want to extract each data member (ID) from selected Names. I can’t do that now.

  I need this for simple scenario:
  
  User have to see Names in combobox, and when he selects all that he wants and then for example click button Go, I want to collect all the IDs from selected rows and send to database to fetch some data from database based on the IDs.

  Thank You.

  Regards

  Hello,

  Currently, it is not possible through C1Multiselect. However, I have escalated the enhancement request to our developer team and will revert you once I get any information from them.

  Thanks,

  It’s definitely available via the Watch window. So it should be possible to get this via reflection.

  Hi All,
  
  In the meantime, you can use below workaround for getting selected record’s ids:

  List<int> selectedIds = new List<int>();       
          private void button1_Click(object sender, EventArgs e)
          {
              selectedIds.Clear();
              C1.Win.Input.C1CheckListSelectedItemCollection col = c1MultiSelect1.SelectedItems;
              for(int selectCnt=0; selectCnt < col.Count; selectCnt++)
              {
                  for (int itemCnt = 0; itemCnt < c1MultiSelect1.Items.Count; itemCnt++)
                  {
                      if (c1MultiSelect1.Items[itemCnt].GetHashCode() == c1MultiSelect1.SelectedItems[selectCnt].GetHashCode())
                      {
                          selectedIds.Add(Convert.ToInt32(dt.Rows[itemCnt]["Id"]));
                      }
                  }
              }
  
              if (selectedIds.Count>0)
              {
                  selectedIds.Sort();
                  MessageBox.Show("Your selected ids: [" + string.Join(",",selectedIds) + "]");
              }
              else
              {
                  MessageBox.Show("You are not select any option.");
              }
          }
  

  Also find the sample application attached for complete implementation.
