After multi-selecting rows of a DataGrid, how do I obtain values of specific columns from those selected rows using the behind-code?

[Bob Gatto]

Hello, I created a DataGrid in my MainPage.xaml file like this:

<syncfusion:SfDataGrid x:Name="GroupVw" ItemsSource="{Binding Grps}" Grid.Row="3" Grid.Column="0"

                               SelectionMode="Multiple" GridLinesVisibility="None" NavigationMode="Row" Margin="30,10,0,0"

                               HorizontalOptions="Center" HeaderRowHeight="0" Loaded="GroupVw_Loaded">

            <syncfusion:SfDataGrid.DefaultStyle>

                <syncfusion:DataGridStyle RowBackground="white" SelectionBackground="blue" SelectedRowTextColor="White"/>

            </syncfusion:SfDataGrid.DefaultStyle>

            <syncfusion:SfDataGrid.Columns>

                <syncfusion:DataGridTextColumn MappingName="GroupId" Width="0"/>

                <syncfusion:DataGridTextColumn MappingName="GroupName" Width="150" HeaderText="Group Name"/>

                <syncfusion:DataGridTextColumn MappingName="GroupTotal" Width="100" HeaderText="Total" CellTextAlignment="Center"/>

            </syncfusion:SfDataGrid.Columns>

        </syncfusion:SfDataGrid>

What I am looking to do is select 1 or more rows from the DataGrid, and each time a row is selected or deselected, an event or method gets executed that will scan through each selected row and use a specific column value of that row.

Is there anyone out there who can help?

I've tried sending this to Syncfusion tech support as a ticket but they keep answering my question in parts, and I usually have to wait at least a full day before I get an answer.

So please help.

Thanks.

Hi Bob,

Based on the information provided, it seems that the problem you are facing is associated with converting the SelectedRows. We can obtain the specific column value by passing the desired column name, which serves as the mapping name for the converted value.

Code snippet :

private void GroupVw_SelectionChanged(object sender, Syncfusion.Maui.DataGrid.DataGridSelectionChangedEventArgs e)

    {

        var selRows = GroupVw.SelectedRows;

        int cntr = selRows.Count;

 

        if (cntr > 0)

            Ans.Text = "Selected: " + (selRows[0] as GroupInfo).GroupId.ToString();

        else

            Ans.Text = "Nothing Selected";

    }
