Can we make a particular column in DataGrid to behave like text box AutoComplete mode?In the GUI, am planning that the user will select a ProductName and will enter the details in the datagrid.The problem I am facing is am not able to set datagrid column to AutoComplete.If I use Textbox or Combobox for the purpose, am not able to enter the selected content into the datagrid because the datagrid is binded to a dataset.

how to set the Textbox autocomplete source to specific column in my datatable?how can i do that?
View 13 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
