How to reproduce the problem
============================
- Create the database and tables (including data) with attached sql files
- Create a WinForms application with an empty RadForm
- Add a new data source to the project and select the created Telerik DB with all tables
- Add a RadGridView to the form
- Create an event handler for the form Load event handler
- Add a TelerikDataSet to the form
- Add an ObjectTableAdapter to the form
- Fill the created adapter from table Object in the form Load event handler
- Add a binding source to the form and set data source to the data set and the member to table Object
- Select radGridView1 and set data source to the created binding source object. Data member is left empty.
- Open Property Builder and press the Build button and create details views
- Run project. Everything looks ok.
- Stop running.
- Select radGridView1 and try to open Property Builder. An error message is generated (see attached file Error messages...
- Save changes and exit studio. Studio is hanging and the process must be kiled.
Hello,
I am having issues with DateTime editor in the grid. We have custom date/time format for our dates - "HH:mm:ss dd-MMM-yyyy" and the datetime editor is set to free form date time with this mask. When user typed a value in the editor it is passed to FreeFormDateTimeProvider.Validate method, which calls DateInput.ParseDate. DateTimeLexer splits this kind of values just fine, but obviously time related tokens comes first and then the date related tokens.
Unfortunately DateTimeParser.Parse method is made the way that it parse date at first and then time from the tokens list. In my case this means time value is parsed and the date value is dropped to default. Why didn't you check that if after ParseDate and ParseTime calls the date portion is null but there are still remaining tokens in the list, so you may call ParseDate one more time?
Do you have any suggestion how could I resolve this issue? Everything related to date time parsing is not extendable at all, starting from DateInput, most of the classes and methods are not public and even some public methods are not virtual. Can I have the Telerik free form date time typing capabilities in the editor but still have time part before date part?
Please run the attached sample project and try to expand a row. The following error occurs:

InnerException:
How can I enter the Value "" (empty string) in the traditional filter system (not Excel like filter).
The grid does not seem to accept an empty string as an argument to "Equals" through the UI.
Ideally I would like to extend the standard filter menu in traditional filtering (and the filter operator drop down in custom filtering dialog) to contain operators "Is Empty" "Is Not Empty" and "Is Null Or Empty", "Is Not Null And Not Empty"

The function OnNotifyPropertyChanged(string propertyName) in RadGridView.cs does not call the base function of RadControl.
RadGridView.cs
protected override void OnNotifyPropertyChanged(string propertyName)
{
if (propertyName == "AutoSize")
{
if (!this.AutoSize)
{
this.RootElement.StretchHorizontally = true;
this.RootElement.StretchVertically = true;
}
else
{
this.RootElement.StretchHorizontally = false;
this.RootElement.StretchVertically = false;
}
}
}
RadControl.cs
/// <summary>
/// Raises the PropertyChanged event
/// </summary>
/// <param name="propertyName">The name of the property</param>
protected virtual void OnNotifyPropertyChanged(string propertyName)
{
this.OnNotifyPropertyChanged(new PropertyChangedEventArgs(propertyName));
}
protected virtual void OnNotifyPropertyChanged(PropertyChangedEventArgs e)
{
PropertyChangedEventHandler handler1 =
(PropertyChangedEventHandler)this.Events[RadControl.PropertyChangedEventKey];
if (handler1 != null)
{
handler1(this, e);
}
}
Because of this i cannot do the following
RadGridView grid = new RadGridView();
grid.OnNotifyPropertyChanged("mypropertyname");
I currently work around this by doing the following
RadGridView grid = new RadGridView();
grid.OnNotifyPropertyChanged(new PropertyChangedEventArgs("mypropertyname"));
I need this functionality because i have a custom control which is derived from RadGridView and it has a custom property that requires databinding with INotifyPropertyChanged. I cannot implement this interface myself because the grid already does this.
I have checked this in both the 2018.1.220 and 2019.1.219 source.
Kind regards,

To reproduce:
- Add items with the same display member open the drop-down and select the second.
- Select another control on the form and then reopen the popup.
- The first item is selected.
Workaround:
class MyMultiColumnComboBox : RadMultiColumnComboBox{
protected override void OnLostFocus(EventArgs e)
{
if (this.DropDownStyle == Telerik.WinControls.RadDropDownStyle.DropDownList)
{
return;
}
base.OnLostFocus(e);
}
}
When you start typing in the search text box some long text, not all key strokes will be handled. Please refer to the attached gifs file illustrating the behavior in the previous version and the latest release.
Please refer to the attached sample project. Run the project and try typing "too long to type" in as your search.
To reproduce:
Update the data source directly and check the OldItems array.

Looks like after last Telerik update to 2019.1.117.40 lilter do digits/numbers is not working any more. When I'd like filter out on decimal columns (or even text column but with linked decimal/int values) I get no results, no rows.
With text columns all is ok.

Steps to reproduce:
- Create a RadGridView
- DataBind the grid to a DataView (it might also fail for other kinds of databinding or content)
- For a column, call BestFit().
- Remove that column from the grid.
- Add the Grid to a parent form or control
- Make the form/control visible.
When the grid is loaded and displayed, a NullReferenceException will be thrown:

Hi
I just found a strange issue using the latest bits of the Telerik RadGridView.
I have a grid that contains ColumnGroupsViewDefinition. Inside one of the group, one of the column is a GridViewComboBoxColumn.
The grid shows correctly on the screen.
If I try to export it using GridViewSpreadExport, I get an exception saying "input string was not in a correct format".
The export works fine if:
-I don't have groups
-I export to HTML using ExportToHTML
-I export to HTML using ExportToCSV
Any help please?
I have the following logic for my View, which has a RadGridView control (add to form at design-time).
GUI is a lightweight view, Controller does the heavy lifting. That part is all good.
However setting the column name and column autosize stuff is a little more "over-complicated" than I'd wish to see. It all works though.
Would be nice to have a "GridViewTextBoxColumnAttribute" as per below, for properties on Custom datasource objects to achieve the same thing in a more concise way.
Or am I missing something and there is a much easier way to do what I want?
I have a number of datasource classes: MyObject, MyCar, MyDog, MyWhatever... that ALL have different property names and datatypes, but may or may-not have the same column name or MasterTemplate style.
Also BestFitColumns is a function of the MasterTemplate, would be nice if it were a property for consistency sake (call to internal function encapsulated in the Set etc), as from a Telerik user's perspective it's just an enum. Then it would be setable in the SmartTag window as well, as functions can't be assigned to.
public partial class RadForm1 : Telerik.WinControls.UI.RadForm, IView
{
public RadForm1)
{
InitializeComponent();
}
private void RadForm1_Load(object sender, EventArgs e)
{
var x = new Controller();
x.SetTemplate(this);
}
public Telerik.WinControls.UI.RadGridView RadGridView()
{
return this.radGridView1;
}
}
public class Controller
{
public void SetTemplate(IView view)
{
var View_RadGrid = view.RadGridView();
View_RadGrid.MasterTemplate.AutoGenerateColumns = false;
View_RadGrid.MasterTemplate.AutoGenerateHierarchy = false;
View_RadGrid.MasterTemplate.AllowColumnResize = false;
View_RadGrid.MasterTemplate.BestFitColumns(Telerik.WinControls.UI.BestFitColumnMode.AllCells);
var cols = new List<Telerik.WinControls.UI.GridViewDataColumn>()
{
new Telerik.WinControls.UI.GridViewTextBoxColumn("DisplayName1"),
new Telerik.WinControls.UI.GridViewTextBoxColumn("DisplayName2")
};
View_RadGrid.MasterTemplate.Columns.AddRange(cols.ToArray());
View_RadGrid.DataSource = new List<MyObject>()
{
new MyObject() { DisplayName1 = "1", DisplayName2 = "2" },
new MyObject() { DisplayName1 = "3", DisplayName2 = "4" }
};
}
private class MyObject
{
[GridViewTextBoxColumnAttribute("DisplayName1", BestFitColumn = Telerik.WinControls.UI.BestFitColumnMode.AllCells, AllowColumnResize = false)]
public string DisplayName1 { get; set; }
[GridViewTextBoxColumnAttribute("DisplayName2", BestFitColumn = Telerik.WinControls.UI.BestFitColumnMode.AllCells, AllowColumnResize = false)]
public string DisplayName2 { get; set; }
}
}
public interface IView
{
Telerik.WinControls.UI.RadGridView RadGridView();
}
[System.AttributeUsage(System.AttributeTargets.Property)]
public class GridViewTextBoxColumnAttribute : System.Attribute
{
private string FieldName;
public Telerik.WinControls.UI.BestFitColumnMode BestFitColumn;
public bool AllowColumnResize;
public GridViewTextBoxColumnAttribute(string fieldName)
{
this.FieldName = fieldName;
}
}
To reproduce: the issue is reproducible in the Demo application >> GridView >> Tabbed Views. Follow the steps from the gif file.
Workaround:
private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
GridDetailViewCellElement cell = e.CellElement as GridDetailViewCellElement;
if (cell != null)
{
cell.MinSize = new Size(e.CellElement.Parent.Size.Width - this.radGridView1.TableElement.GroupIndent , 10);
}
}
This was working this way in 2017 then we changer it so all rows are affected. Bot modes should be supported.
To reproduce: please run the attached sample project and follow the steps illustrated in the attached gif file:
Scrolling to a newly added row does not work when inner templates are visible.
Add data to the inner templates of several rows near the bottom using the button.
Expand these inner templates so they are all visible.
Scroll back up to the top.
Add a new item to the outer grid normally.
The table will jump to where it things the new item is but will fall short, instead scrolling to a location in one of the inner templates.
Workaround:
private void RadGridView1_UserAddedRow(object sender, GridViewRowEventArgs e)
{
foreach (GridViewRowInfo row in this.radGridView1.Rows)
{
if (row.IsExpanded)
{
row.IsExpanded = false;
row.IsExpanded = true;
}
}
}
To reproduce: Initially, the row at index 0 is white, when you move it to index 5 it is still white until you hover it:
public RadForm1()
{
InitializeComponent();
this.radGridView1.Columns.Add("Data");
for (int i = 0; i < 100; i++)
{
this.radGridView1.Rows.Add(i);
}
this.radGridView1.EnableAlternatingRowColor = true;
this.radGridView1.TableElement.AlternatingRowColor = Color.Aqua;
}
private void radButton1_Click(object sender, EventArgs e)
{
this.radGridView1.Rows.Move(0, 5);
}
Workaround:
private void radButton1_Click(object sender, EventArgs e)
{
this.radGridView1.Rows.Move(0, 5);
this.radGridView1.Rows[5].InvalidateRow();
}
