Hello,
I have an UltraWinGrid whose datasource is set to a BindingList object. For instance,
this.gridCar.DataSource = this.listCars;
Now, I need one of the columns to be a UltraComboEditor control. So, I'm writing this:
this.gridCar.DisplayLayout.Bands[0].Columns[0].EditorControl = this.comboBrands;
But... when I run the application, no combo is shown.
I have already tried to set the Style property to DropDownList style, but nothing works.
It seems the column does not accept any kind of embedded editor.
Is there anything wrong with my code?
Could you give me a clue why is this not working?
Thank you in advance.
Best Regards,
Pedro Rosas
Hi Pedro,
My first question is, what exactly are you trying to accomplish by assigning an UltraCombo to the column? If you just want a dropdown list in a column, there are better ways to do it than using an UltraCombo. UltraCombo is probably the least efficient way. Here's a link with more info.
HOWTO:What is the best way to place a DropDown list in a grid cell?
Regarding why it's not working, Matt's point is a valid one. You should probably refer to the column by it's Key rather than Index.The Index of a column may change, but the Key will not.
Another possiiblity is that the column in question is not editable. You cannot have a dropdown list in a column that is read-only or disabled. Are you able to type into the column?
