How to add Checkbox into the first column?

[wg]

Hi,

I want to add Checkbox into the first column, like Assembly Minifier of telerik (Actually is Minifier made of TreeListView?)

Also please check the attached pic.

Thanks in advance,
Bill

Hello wg,

 You can use a GridViewCheckBoxColumn and bind it to a boolean property of your model.

 The Assembly Minifier currently uses RadTreeView, as work on it began before the rewriting of RadTreeListView.

Hi Yavor,

Thank you so much for the quick answer.

Maybe I should not ask here, but how to define multiple column with RadTreeView? I took a look at the demo of RadTreeView but I didn't find it. So, looks RadTreeView misses multiple column and TreeListView misses Checkbox?

Or how can I build a layout like Assembly Minifier with both  Multiple column and Checkbox?

Thanks,
WG

Hello wg,

 RadTreeView does not support a true multi-column layout by design. Checkbox selection is built-in, as detailed in this demo.

 You can also insert a GridViewCheckBoxColumn in RadTreeListView to also achieve a CheckBox, which you can bind to a property of your data object.
