GridView - default to nothing selected

Eery time I use the GridView, I have to remember to un-select the last item in the list.

This is almost always to wrong thing to be selected - so why select it by default?

..and the way to swith this 'feaure' off isn't obvious - I always have to look it up....RadGridView1.CurrentRow = Nothing

No problem - I understand the need to protect existing cutomers.

I'm one of them :-)

Hello, Ian,

I am glad that the suggested solution fits your scenario. To be honest the SelectLastAddedRow property was introduced a very long time ago. Its default value has always been true. Changing the default value to false would have a huge impact over all existing projects of our clients. Even though it is just a simple property, it is expected to be a massive change for the existing customers. That is why we would consider improving this behavior in case we receive similar requests from other customers.

Thank you for your understanding.

I'm happy that there are ways to avoid this happening - the single line of code does it perfectly.

My only suggestion was that maybe the default for un-bound grids would be not to highlight the last row.

Hello, Ian,

Thank you for specifying that you are using unbound mode.

I would recommend you to set the MasterTemplate.SelectLastAddedRow property to false. Thus, adding rows programmatically wouldn't manage the CurrentRow in RadGridView:

        public RadForm1()
        {
            InitializeComponent();

            this.radGridView1.MasterTemplate.SelectLastAddedRow = false;
            this.radGridView1.Columns.Add("Text");
            this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
            for (int i = 0; i < 5; i++)
            {
                this.radGridView1.Rows.Add(Guid.NewGuid().ToString());
            }
        }

I believe that it would fit yoru scenario.

Hi Dess,

All my GridViews are populate by data from another system, not using data binding. So I manually create GridViewDataRowInfo instances, and add them to the rows.

Hello, Ian,

Usually, when the RadGridView.DataSource is set, the current row is synced with the current position in the applied DataSource collection. It is designed and expected behavior. Since it is not clear according to the provided information how RadGridView is populated with data, could you please elaborate?

A sample code snippet or a runnable project would be greatly appreciated. Setting the CurrentRow property to null after data binding is a good approach for clearing the selection/highlighting.

Thank you in advance for your cooperation. I am looking forward to your reply.
