  Hello,

  I’m using the code below to load my multiselect control with all columns from C1Screen1 Grid control. How do I automatically select all the columns in my MultiSelect control and hide a column when its column name is deselected and show the column when it’s column name is selected?
  
  Also when I place my mouse on a column name of the Multiselect control how do I display a description? For example when place my mouse on the row with NSN, would like to display description as National Stock Number below or above the NSN…

  For ida As Integer = 0 To C1Screen1.Splits(0).DisplayColumns.Count - 1
  
  C1MultiSelect1.Items.Add(C1Screen1.Splits(0).DisplayColumns(ida).Name)
  
  Next
  
  C1MultiSelect1.TagWrap = True

  Thanks,

  Victor

  Hello Prabhat,

  Enclosed is a sample project. Initially, I would like to see to all the Grid’s columns in the Multiselect control selected, and when I deselect a particular column I would like to hide it in the Grid and when I select it again I would like to see it in the Grid.

  Thanks,

  Hello Prabhat,

  How do I view the definitions when I place the mouse the rows? For example if I place mouse over the row with NSN, would like to display next to it “National Stock Number”

  Thanks,

  Victor

  Hello Prabhat,

  Thank you for the solution but I meant when hovering over the row of the MultiSelect control not the column of the Grid control…

  Thanks,

  Victor

  Hi Victor,

  Sorry for the confusion.
  
  Currently, it is not possible to get the hovered item in MultiSelect so we have escalated this request to the devs and will let you know once we get any updates on this from their end.

  Hello Prabhat,

  Similar to the dropdown control inside a Grid. In the MultiSelect control, is it possible to have a “Select All” on the first row automatically selected, and clear all the selection if I deselect it?

  Thanks,

  Victor

  Hi Victor,

  You can use the ShowSelectAll property of the C1MultiSelect to true to show select all checkbox or not.
