Expand a row to show a UserControl

[j0rge]

Hi,

1. Is it possible to create a button (image button would be nice since the GridViewCommandColumn is just wrong for this, it should be a + and -) per row? I know you do not support Hierarchies but can I "infuse" a button?

2. On that button click I would like to increase the height of the Row to add a user control that will show details, pie charts, etc. This usercontrol should be as wide as the whole row (not only a cell).

I am thinking of hacking into  the source code but now when Q2 is comming up... well it would be better not to have to migrate that code every time a service pack or version of the Telerik controls is released.

Thanks,
/ jorge

Hi j0rge,

Thank you for writing us.

Currently it is not possible to embed such a user control in our grid control. Nevertheless, this is a nice and powerful feature and we will add it tp our high priority to do list. However, since this is a major feature we can't give you a strict deadline. Still, we will work to deliver it in the near future.

Regarding your first question, consult the codeblock below:

// put this code in your form's load method
this.samplTableTableAdapter.Fill(this.sampleDatabaseDataSet.SamplTable);
this.radGridView1.Columns.Add(new GridViewDataColumn( "Button" ));

void radGridView1_CellFormatting( object sender, Telerik.WinControls.UI.CellFormattingEventArgs e )
{
    //this example put progress bar into column "Button"
    if (e.CellElement.ColumnInfo is GridViewDataColumn && ((GridViewDataColumn)e.CellElement.ColumnInfo).DataField == "Button")
    {
        if (!(e.CellElement.RowElement is GridHeaderRowElement)) //exclude Header element in the data column
        {
            if (e.CellElement.Children.Count > 0)//the progress bar is already added to cell
                return;
            RadButtonElement button = new RadButtonElement();
            button.Text = "+ / -";
            button.Click += new EventHandler( button_Click );
            e.CellElement.Children.Add( button );
            ApplyThemeToElement(button, "ControlDefault");

        }
    }
}

 private void ApplyThemeToElement(RadItem item, string themeName)
{
    DefaultStyleBuilder builder = ThemeResolutionService.GetStyleSheetBuilder(item.ElementTree.Control,
        item.GetThemeEffectiveType().FullName, string.Empty, themeName) as DefaultStyleBuilder;

    if (builder != null)
        item.Style = new XmlStyleSheet(builder.Style).GetStyleSheet(); //clone because control might modify it later
}

Thanks again for contacting us. Your feedback is important in letting us know how to develop your products so that they would be most useful to you.

All the best,
