View 3 RepliesI've got a combo box that's bound to a virtualpathbinding source. The column it's bound to (Display and value members) have duplicates that I'm trying to hide/remove.
I cannot remove the duplicates programatically as it errors (the control is bound, cannot change data).
I need to get all the different values from my dgv, but no duplicates, and add them as rows to my dataset.for example if my dgv col1 have the following values:
a
b
c

the procedure must get the values from dgv1 and add it to a dataset if the values isnt already there.My dataset should have this:

The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime
