Hello Hassan,
Thank you for this clarification. Please note that unless there is specifically provided version in the forums we do test with the latest one and we do provide replied based on our investigations with the latest vesion.
Indeed, I can confirm that this code does not work with your version. However, with the very next version of the suite (2012.1.12.215) everything works as expected.
To work around the issue in your version you need to create custom visual item as the following one:
public class CustomSimpleListViewVisualItem : BaseListViewVisualItem
{
protected override SizeF MeasureOverride(SizeF availableSize)
{
if (this.Data == null)
{
return SizeF.Empty;
}
if (this.dataItem.Owner.ShowCheckBoxes)
{
this.ToggleElement.Visibility = ElementVisibility.Visible;
}
else
{
this.ToggleElement.Visibility = ElementVisibility.Collapsed;
}
float indent = 0;
if (this.Data.Owner.ShowGroups &&
(this.Data.Owner.EnableCustomGrouping || this.Data.Owner.EnableGrouping) &&
this.Data.Owner.Groups.Count > 0)
{
indent = this.Data.Owner.GroupIndent;
}
SizeF desiredSize = base.MeasureOverride(LayoutUtils.InfinitySize);
desiredSize.Width += this.ToggleElement.DesiredSize.Width;
if (this.Data.Size.Height > 0)
{
desiredSize.Height = this.Data.Size.Height;
}
if (this.Data.Size.Width > 0)
{
desiredSize.Width = this.Data.Size.Width;
}
RadListViewElement listViewElement = this.Data.Owner;
if (listViewElement != null && !listViewElement.AllowArbitraryItemWidth)
{
desiredSize.Width = listViewElement.ItemSize.Width;
}
if (listViewElement != null && !listViewElement.AllowArbitraryItemHeight)
{
desiredSize.Height = listViewElement.ItemSize.Height;
}
if (listViewElement != null && listViewElement.AllowArbitraryItemHeight && !listViewElement.AllowArbitraryItemWidth)
{
SizeF measuredSize = base.MeasureOverride(new SizeF(desiredSize.Width, float.PositiveInfinity));
desiredSize.Height = measuredSize.Height;
}
if (listViewElement != null && listViewElement.AllowArbitraryItemWidth && !listViewElement.AllowArbitraryItemHeight)
{
SizeF measuredSize = base.MeasureOverride(new SizeF(float.PositiveInfinity, desiredSize.Height));
desiredSize.Width = measuredSize.Width;
}
if (listViewElement != null && listViewElement.FullRowSelect)
{
desiredSize.Width = Math.Max(float.IsInfinity(availableSize.Width) ? 0 : GetClientRectangle(availableSize).Width, desiredSize.Width + indent);
}
SizeF clientSize = GetClientRectangle(desiredSize).Size;
RadItem editorElement = this.GetEditorElement(Editor);
SizeF sizef = new SizeF(clientSize.Width - this.ToggleElement.DesiredSize.Width, clientSize.Height);
if (IsInEditMode && editorElement != null)
{
float editorWidth = Math.Min(clientSize.Width - this.ToggleElement.DesiredSize.Width - indent, availableSize.Width - indent);
editorElement.Measure(new SizeF(editorWidth, float.PositiveInfinity));
desiredSize.Height = Math.Max(desiredSize.Height, editorElement.DesiredSize.Height);
sizef.Height = desiredSize.Height;
}
this.layoutManagerPart.Measure(sizef);
//this.Data.ActualSize = desiredSize.ToSize();
PropertyInfo prop = this.Data.GetType().GetProperty("ActualSize");
if (null != prop && prop.CanWrite)
{
prop.SetValue(this.Data, desiredSize.ToSize(), null);
}
return desiredSize;
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(SimpleListViewVisualItem);
}
}
}
To put this item in action, you should use the VisualItemCreating event:
I hope this helps.
