Hello hirak,

You may handle the Click event of the button and find its corresponding row by the ParentOfType<T> extension method. Afterwards, you may either set the Background property of the row or set it as selected.

 

All the best,

Hi hirak,

In case the definition of the column is as follows:

<telerik:GridViewColumn>
                    <telerik:GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadButton Content="SelectTheRow" Click="RadButton_Click" />
                        </DataTemplate>
                    </telerik:GridViewColumn.CellTemplate>
                </telerik:GridViewColumn>
                <telerik:GridViewColumn>

The Click event may be handled like:
private void RadButton_Click(object sender, RoutedEventArgs e)
        {
            var button = sender as RadButton;
            var row = button.ParentOfType<GridViewRow>();
            if(row != null)
            {
                row.IsSelected = true; 
          //or set its background:
          //row.Background = new SolidColorBrush(Colors.Tomato);      
            }
        }

 

Kind regards,
Maya

Hi hirak,

If you chose the case of selecting the row, you may use directly the SelectedItem property of the grid to get the corresponding item. Otherwise, you may get the item as follows:

private void RadButton_Click_1(object sender, RoutedEventArgs e)
        {
            var button = sender as RadButton;
            var row = button.ParentOfType<GridViewRow>();
            if (row != null)
            {
                row.Background = new SolidColorBrush(Colors.Tomato);
                var item = row.Item as Club;
            }
        }

In this case Club is the business object of the grid.

Hi,

Selection of row on click of button is behaving in a weird way.

It is highlighting different rows rather than the one on which the button is placed and clicked.

Please, update if the code which have send is correct.

Thanks & Regards,
Hirak

Hi,

The highlighting of rows is happening every 30th column and sometimes after every 19th or 6th column.

Please clarify, what is the cause of this behaviour.

Any quick solution to this issue will be highly appreciated.

Thanks & Regards,
Hirak

I used the same code. When I clicked on the button, the outline of that row will become red.  Then, I click on another row, the new row will have outline as red but the previous clicked row will have background red. How can I remove the background red from previous clicked button row? The IsSelected is working correctly.
var btnChange = sender as RadButton;
var row = btnChange.ParentOfType<GridViewRow>();
if (row != null)
{
    row.IsCurrent = true;
    row.IsSelected = true;
    row.Background = new SolidColorBrush(Colors.Red);
}

Hi Bertha,

If you want to modify the appearance of the selected row, you can predefine its template using Microsoft Expression Blend. There you should modify the Border element named Background_Selected in the way you need. I can suggest you to check this help article for a reference.

I hope this information helps.

Hello Raj,

Based on the info you provided, I guess "King" and "Name" are properties of your business object - let's say "Person". Once you cast the item - var person = row.Item as Person;, you will then be able to get its properties like var name = person.Name;
