Select group level checkboxes

Saradhi posted over 13 years ago

I have a multi level grouping (let's say two groups) and one of the column is Checkbox column.

My functionality is when I select the checkBox in Header column I should be able to loop through all the group row level checkboxes and select all the check boxes in group level rows.

and when I select the checkBox in group1 (let's main group) I should be able to loop through all the sub-group level checkboxes and select all the check boxes in sub-group level rows.

I am able to select the corresponding checkBoxes in the actual data rows on the selection of Header checkbox/main group checkbox/Sub-group checkbox but could not get hold of group level checkboxes.

Can some please help on this?

Thanks

Hi Sayap,

To access the row data of a particular GroupByRow, you can use:

RowCollection rows = ((GroupByRow)this.grid1.Rows[0]).Rows;

foreach (Row row in rows)

{

}

Hope this helps,

Hi Steve

How can identify the actual GroupbyRow in a xamgrid?

When I click on a column header (with a checkbox), how to get the row collection?

Thanks

Hi Steve,

I got the same question as Harold E. How do we get the row collection? (given user clicks on the checkbox from the sub group level header row, so that I can only select/unselect the belonging rows' checkboxes)

Please advise.

Hi,

Assuming your checkbox is defined in the header using a HeaderTemplate:

<ig:CheckBoxColumn Key="Bool">
    <ig:CheckBoxColumn.HeaderTemplate>
        <DataTemplate>
            <CheckBox Click="CheckBox_Click" />
        </DataTemplate>
    </ig:CheckBoxColumn.HeaderTemplate>
</ig:CheckBoxColumn>

You can access all rows in the given collection with the following code:

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
    CheckBox cb = (CheckBox)sender;
    HeaderCellControl cell = (HeaderCellControl)cb.Parent;

    foreach (RowBase row in cell.Cell.Row.Manager.Rows)
    {
        if (row.RowType == RowType.DataRow)
        {
            ((MyDataObject)row.Data).Bool = (bool)cb.IsChecked;
        }
    }
}

 

Hope this helps,
