WPF - Making a checkbox select rows within a data grid

Ray Dean

Hi All.

New to C# programming, I set myself a challange to build a GUI application. The application populates a datagrid with data from a table. I have a checkbox added to the datagrid column, and what I would like is for the checkbox to be the sole method for selecting items within the datagrid. So if the checkbox is checked 10 times for 10 datagrid items selected, those items are selected from the datagrid. This is what I have so far and I am stuck with the checkbox issue.

As can be seen below, despite selecting server id 7,8 the datagrid row only recognises 3 as its the only one highlighted.

"GridServerList" CanUserAddRows="False" AlternatingRowBackground="Beige" Grid.Column="5" HorizontalAlignment="left" Height="365" Width="625" AutoGenerateColumns="False" Margin="9,159,0,0" VerticalAlignment="Top" Grid.ColumnSpan="8" SelectedItem="{Binding PopulateDataGrid, Mode=TwoWay}" >
"chkSelectedServer" Binding="{Binding IsChecked, Mode=TwoWay}" Header="Choose" IsReadOnly="False" CanUserSort="False">
"CheckBox" BasedOn="{StaticResource {x:Type CheckBox}}" >
"Checked" Handler="OnChecked" />
"{Binding Server_Id}" Header="Server_Id" IsReadOnly="true"/>
"{Binding Server_Name}" Header="Server_Name" IsReadOnly="true"/>

Within my CS file, I do not have any code relating to the functionality that I require.

Follow the article, the complete step by step solution. https://www.aspsnippets.com/Articles/Add-CheckBox-Column-to-DataGridView-in-Windows-Forms-application-using-C-and-VBNet.aspx

to get columns value of all selected row (checked row) as a dataTable
private DataTable GetSelected()
{
    DataTable dt = new DataTable();
    dt.Columns.Add("ServerId");

    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
        bool isSelected = Convert.ToBoolean(row.Cells[0].Value);
        if (isSelected)
        {
            dt.Rows.Add(row.Cells[1].Value,);
        }
    }
    return dt;
}

There were plenty of adding a checkbox in your datagridview, I strongly encourage you to use one of the following instead of CheckBoxColumn

If you are binding data from database then add a column of Bit datatype which stores 0 or 1, when you bind with gridview, it will shown as checkbox

OR

In the same way, if using DataTable, then add a column of bool datatype.

Its far easy way, not in terms of showing checkboxes but also retreiving of checked/unchecked items.

Good Luck
