Right now I set up the label's margin in xaml

But I want to use property binding, so I created the property in View Model. The type of property is Thickness. But it is not working. I doubt that CategoricalAxis doesn't support it because I saw an example.

Thanks for advice.

In order to create a Custom editor with RadGridView by following a guide at: Create Custom Editor with RadGridView

It looks OK, but I would change the DataMemberBinding to Int32 instead of System.Windows.Media.Color, because System.Windows.Media.Color belongs to View class I don't really want to use it in my ViewModel. The converter looks like:

I use gridview to display a datatable, when columns count is 2000 and rows count is 100, the UI can not render out,

there is a compromise solution is divide the datatable and display them by many gridview side by side,but when drag the horizontal scroll bar，it is not smooth

How to raise the rendering efficiency of gridview

and is there a probably render limit of the gridview , how many columns and how many rows

Hi,

I created a little UI that allow user to personalize the GridView properties.

I a section of this UI, a user can add a "Format Condition" defining an Expression (using RedExpressions) and some Style preferences, in example a row background.

When a FormatCondition class is created, in the constructor, I add a StyleRule to GridView.RowStyleSelector, I bind the StyleRuleCondition to FormatCondition.Condition and I'm waiting for BackGround changes:

            Grid = g;
            Css = (ConditionalStyleSelector)(g.RowStyleSelector ?? (g.RowStyleSelector = new ConditionalStyleSelector()));
            StyleRule = new StyleRule();
            StyleRule.Bind(StyleRule.ConditionProperty, Condition, converter: new Converters.FunctionConverter<string, System.Linq.Expressions.Expression>(Convert));
            StyleRule.Style = new System.Windows.Style(typeof(GridViewRow)
, (Style)Application.Current.FindResource("GridViewRowStyle"));
            Css.Rules.Add(StyleRule);
            BackGroundColor.ValueChanged += (p) => ResetBg();

If BackGround change I edit the Background setter:

if (BgSetter != null) Style.Setters.Remove(BgSetter);

BgSetter = null;

if (!BackGroundColor.Value.HasValue) return;

BgSetter = new Setter(GridViewRow.BackgroundProperty, new SolidColorBrush(BackGroundColor.Value.Value));
Style.Setters.Add(BgSetter);

I think this is logically correct but Grid Style don't change until a rows refresh occours.

How I can force grid to re-evaluate row stryle rules?

When I click the grid view's "add new item" button, it shows a text box where to type in the value for the new row. I want show Window's on screen keyboard when the text box is clicked/tapped. I.e., I start a new Process that starts TabTip.exe for every other text box in my application.

Is there an easy way to do this with the grid view's text box or do I have to override a certain grid view's style? If so, which one?

I took a quick look at the your style structure topic but couldn't find the text box in the styles. I think the text box container is PART_DataCellPresenter because the text box was not displayed after I commented PART_DataCellPresenter out in the style.

The way I have handled this with other text boxes is that I have created a new class that extends TextBox. Then I subscribed to the PreviewLeftMouseUp event whose handler starts TabTip.exe. Maybe I can override some grid view's style to use my extended class or if you have a better solution.

If I set RadTreeViewItem Background it highlights the header only. How can I highlight the whole line?

I have a bar series. I use the default setting. Now I want to customize the margins. See the expected image.

Do not worry about the bar color. I only need to set the margins. I have no idea to do it.

If you could post a sample project, that would be great. Thanks.

Is there a simple way to get the text in a RadComboBox and a TextBox to be aligned?  Both controls are aligned but the text within the controls are slightly misaligned.

Thanks,

Bob
