GridControl BeforeSelect Event

[Qingde Shi]

Hi,

How to simulate the GridControl to have a BeforeSelect event for a cell or a row? like the BeforeSelect event in the TreeView Control, user can cancel the selection.

Many thanks.

Hi Q,

There are Grid.Model.SelectionChanging(before selection) and Grid.Model.SelectionChanged(after selection) events that you can use to monitor changing selections.

Hi Haneef,

I managed to make BeforeSelect event working. However, the SelectionChanged event was raised at least twice when using ArrorKey to change the selection. Any ideas about how to use SelectionChanged event only once no matter what is the selection change Reason?


Thanks,

Hi Haneef,

I kink of solved the problem by not using the change Reason but caching selected row index and check if selected row index changed.

Now I have another question. To use the GridListControl, do I have to set items by binding to DataSource? Can I do something like this, gridListControl.Items.Add(object value)? the Items property is null by defaut.

Thanks.

Hi Q,

You can set the DataSource property of the GridListControl to bind the datatable.If you want to see multiple column in a list then enable the MultiColumn property. Below is a code snippet


this.gridListControl1.MultiColumn = true;

this.gridListControl1.DataSource = this.dataSet11.Tables["Products"];
