Is this how the titlebar for the telerikmetrotouch theme should look? With the deep line over the control buttons to the right, but shallow over the form name?

I'm seeing it on each form, but would rather it were the same depth over the whole title bar. Im pretty sure the project manager will complain when he sees it.

[Solved] GridView Virtualization CustomColumn

Good evening,

I was trying to implement a generic column where depending the type of object being bind to it, different editors would be used.

At this moment i've settled for boolean, text and list and everyting is working well except the display of the checkbox.

The following happens: GridVirtualization

As you can see in the picture above, the top of the grid shows up fine, but on the bottom the checkboxes show up as text, as i use the scroll bar the lines eventually refresh to display the checkboxes(wich is why i assume this is something regarding the UI Virtualization).

I have tried invallidating rows, using dgvCustomer.TableElement.Update(Telerik.WinControls.UI.GridUINotifyAction.Reset) and a couple of alternatives that i have forgotten meantime.

The setup uses 3 custom cells, and the following custom column.

01.using System;

02.using System.Collections.Generic;

03.using Telerik.WinControls.UI;

04.

05.namespace Inl.TelerikExtensions40.WinForms

06.{

07. public class GenericDataColumn : GridViewDataColumn

08. {

09.

10. public GenericDataColumn() : base()

11. {

12. }

13.

14. public GenericDataColumn(string fieldName) : base(fieldName)

15. {

16. }

17.

18. public GenericDataColumn(string uniqueName, string fieldName) : base(uniqueName, fieldName)

19. {

20. }

21.

22. public override Type GetCellType(GridViewRowInfo row)

23. {

24. if (row is GridViewDataRowInfo)

25. {

26. if (row.Tag != null)

27. {

28. var types = (Dictionary<int, Type>)row.Tag;

29. if (types.ContainsKey(base.Index))

30. {

31. return types[base.Index];

32. }

33. }

34.

35. return typeof(CustomTextBoxCell);

36. }

37. return base.GetCellType(row);

38. }

39.

40. public override Type GetDefaultEditorType()

41. {

42. var cellType = GetCellType(base.OwnerTemplate.DataView.CurrentItem);

43.

44. if (cellType == typeof(CustomTextBoxCell)) {

45. return typeof(RadTextBoxEditor);

46. }

47. if (cellType == typeof(CustomCheckBoxCell))

48. {

49. return typeof(CustomCheckBoxEditor);

50. }

51. if (cellType == typeof(CustomComboBoxCell))

52. {

53. return typeof(RadDropDownListEditor);

54. }

55.

56. return base.GetDefaultEditorType();

57. }

58.

59. public void SetType(Enumeration.DataTypesEnum tipo, GridViewRowInfo row)

60. {

61. Dictionary<int, Type> types = default(Dictionary<int, Type>);

62.

63. if (row.Tag != null)

64. {

65. types = (Dictionary<int, Type>)row.Tag;

66. }

67. else

68. {

69. types = new Dictionary<int, Type>();

70. }

71.

72. if (types.ContainsKey(base.Index) == false)

73. {

74. switch (tipo)

75. {

76. case Enumeration.DataTypesEnum.Texto:

77. types.Add(base.Index, typeof(CustomTextBoxCell));

78. break;

79. case Enumeration.DataTypesEnum.Booleano:

80. types.Add(base.Index, typeof(CustomCheckBoxCell));

81. break;

82. case Enumeration.DataTypesEnum.Lista:

83. types.Add(base.Index, typeof(CustomComboBoxCell));

84. break;

85. }

86. }

87.

88. row.Tag = types;

89. //row.InvalidateRow();

90. }

91. }

92.}

I'll be willing to supply any other code necessary.

Thank you in advance.

[Solved] Custom search with scrolling in the datagrid

Hello Telerik Team,
at our project we have specific request on search feature in datagridview. When user starts typing in datagrid we have to perform incremental search in selected column (in THE column that is sorted) as user types. At the same time the grid should scroll through records the datagrid.

I know the similar functionality in that use case is achieved via filter, but customer want to have all the items in the grid while searching for the record.

is there any easier way to implement this (than my solution mentioned lower)? Perphaps by telerik API?

It's just a first draft because i will have to extend this code so that typed string is somehow "visible" to the user)

private string searchString = "";
        private void grdKlienti_KeyPress(object sender, KeyPressEventArgs e)
        {
            searchString += e.KeyChar;
            int sortColumn = grdKlienti.Columns.Where(a => a.IsSorted).First().Index;

            int scrollTo;
            for (scrollTo = 0; scrollTo < grdKlienti.RowCount; scrollTo++)
            {
                if (grdKlienti.Rows[scrollTo].Cells[sortColumn].Value.ToString().StartsWith(searchString))
                {
                    break;
                }
            }

            grdKlienti.GridElement.ScrollToRow(scrollTo);
        }

Styling RadGridView Relationship Tabs

I'm a creating my own theme using the Visual Style Builder for WinForms. I have styled much of the RadGridView the way that I want to except the Relationship tabs (Captions). They are confusing me. I don't see them. Are they under another control? I don't see them in the preview or design mode for the RadGridView. What I am referring to is the GridViewRelation when there is more than one for a GridViewTemplate, it shows tabs. I want to style those in a theme (hopefully not in code at runtime).

Multiple rulers

Hi.

I'd like to use the scheduler for a work time recording software where users can enter their worktime by creating events in the scheduler.
There is also a time clock in the office and I'd like to highlight the times when users came in or left the office, just like the ruler does.
So, is it possible to draw two rulers per day? Or is it possible to draw custom lines?
Right now, I am changing the background color of the timespan where the user is in the office, but that approach has a low performance
because I handle that in the CellFormatting event and I have to check if the current cell is in that timespan.
