Workaround:
Set the MaxDate in the custom provider:
Public Class MyMaskDateTimeProvider
Inherits MaskDateTimeProvider
Public Sub New(mask As String, culture As CultureInfo, owner As RadMaskedEditBoxElement)
MyBase.New(mask, culture, owner)
Me.MaxDate = DateTime.MaxValue
End Sub
End Class
Hi,
I am working with the RadGridView in my c# winform application. I am using the custom font ("Font Awesome 5 Free Solid") for the RadGridView using the "CellFormatting" event to view the icons along with the text. Here i am able to see the proper icons with text but when i open the filter menu to filter out the rows, i am unable to see the icons (icons shown as the box) as in filterbox we don't have any custom font.
I tried to working out the properties of the RadTreeNodeCollection but here we dont have any Custom font property for the same.
i want to show the text as it is in the filterbox along with the text and the icon.
so can you suggest what i can do to view the icons in the filterbox?
Check the attachment for reference.
Everithing works fine but is it possible to set the parent row to collapsed, if there are child rows?
I might be missing something, but I have Hyperlinks in a column in my RadDatGridView.
I tried searching for a Support document explaining this, but didn't find any.
When the grid is exported to excel all data is coming across, but the column with hyperlink is not
a hyperlink in Excel.
Below is sample of the code used to make the "HyperLink" column in my grid.
radGridView1.DataSource = dtResults;
radGridView1.Columns.Remove("Path");
GridViewHyperlinkColumn col = new GridViewHyperlinkColumn();
radGridView1.Columns.Insert(5, col);
col.Width = 200;
col.FieldName = "Path";
col.HeaderText = "Path";
col.Name = "Path";
Coded used to do the Export....
GridViewSpreadExport spreadExporter = new GridViewSpreadExport(this.radGridView1);
spreadExporter.ExportVisualSettings = true;
SpreadExportRenderer exportRenderer = new SpreadExportRenderer();
spreadExporter.RunExport(filename, exportRenderer);
Thanks.
Roger
Hello,
In our Environment it's not possible to assign a GroupComparer to another GridView template then MasterTemplate. The GroupComparer property is always null after assignment.
It's possible to assign our custom comparer to the MasterTemplate and it will be triggered, but not in another template then MasterTemplate.
Best regards.

Using a custom control using the Telerik Presentation Framework, I am receiving a NullException inside the GridCheckBoxHeaderCellElement during the GridViewElement's data load.
The custom control construction follows an example I found somewhere (reference is lost to me at this point):
ControlContainingGridView inherits from RadControl
CreateChildItems creates and adds ControlContainingGridViewElement
ControlContainingGridViewElement inherits from RadElement
CreateChildItems creates and adds some layout controls AND a GridViewElement
public partial class ControlContainingGridView : RadControl {
public ControlContainingGridView() {
InitializeComponent();
this.TextChanged += ControlContainingGridView_TextChanged;
}
private void ControlContainingGridView_TextChanged(object sender, EventArgs e) {
controlContainingGridViewElement.Text = this.Text;
}
private ControlContainingGridViewElement controlContainingGridViewElement = null;
protected override void CreateChildItems(RadElement parent) {
controlContainingGridViewElement = new ControlContainingGridViewElement();
this.RootElement.Children.Add(controlContainingGridViewElement);
base.CreateChildItems(parent);
}
public object DataSource {
get {
return controlContainingGridViewElement.GridView.Template.DataSource;
}
set {
try {
controlContainingGridViewElement.GridView.Template.DataSource = value;
} catch (Exception ex) {
Debug.WriteLine(ex);
}
}
}
internal void SetupColumns(Action<MasterGridViewTemplate> setupColumns) {
controlContainingGridViewElement.GridView.Template.AutoGenerateColumns = false;
setupColumns(controlContainingGridViewElement.GridView.Template);
}
}
public class ControlContainingGridViewElement : RadElement {
private TextPrimitive textPrimitive = null;
private RadButtonElement addButton = null;
private RadButtonElement deleteButton = null;
private RadGridViewElement gridViewElement = null;
public RadGridViewElement GridView { get { return gridViewElement; } }
public bool ShowAddButton { get { return addButton.Visibility == ElementVisibility.Visible; } set { addButton.Visibility = value ? ElementVisibility.Visible : ElementVisibility.Collapsed; } }
public bool ShowDeleteButton { get { return deleteButton.Visibility == ElementVisibility.Visible; } set { deleteButton.Visibility = value ? ElementVisibility.Visible : ElementVisibility.Collapsed; } }
public string Text { get { return textPrimitive.Text; } set { textPrimitive.Text = value; } }
protected override void CreateChildElements() {
DockLayoutPanel dlp = new DockLayoutPanel();
dlp.StretchHorizontally = true;
dlp.StretchHorizontally = true;
dlp.LastChildFill = true;
DockLayoutPanel dlpBar = new DockLayoutPanel();
dlpBar.StretchHorizontally = true;
DockLayoutPanel.SetDock(dlpBar, Dock.Top);
var imagePrimitive = new ImagePrimitive();
DockLayoutPanel.SetDock(imagePrimitive, Dock.Left);
textPrimitive = new TextPrimitive();
DockLayoutPanel.SetDock(textPrimitive, Dock.Left);
var slp = new StackLayoutPanel();
DockLayoutPanel.SetDock(slp, Dock.Right);
var addButton = new RadButtonElement {
Text = "Add",
MaxSize = new Size() { Height = 20 }
};
var deleteButton = new RadButtonElement {
Text = "Del",
MaxSize = new Size() { Height = 20 }
};
slp.Children.Add(addButton);
slp.Children.Add(deleteButton);
dlpBar.Children.Add(slp);
dlpBar.Children.Add(imagePrimitive);
dlpBar.Children.Add(textPrimitive);
gridViewElement = new RadGridViewElement {
StretchHorizontally = true,
StretchVertically = true
};
gridViewElement.Template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
gridViewElement.Template.AllowAddNewRow = false;
gridViewElement.Template.AllowDeleteRow = false;
gridViewElement.Template.AllowDragToGroup = false;
gridViewElement.ShowGroupPanel = false;
gridViewElement.ShowGroupPanelScrollbars = false;
dlp.Children.Add(dlpBar);
dlp.Children.Add(gridViewElement);
this.Children.Add(dlp);
base.CreateChildElements();
}
}
During Form load, I programmatically add columns and provide a binding source
private List<SampleModel> sampleModels = new List<SampleModel>();
private BindingSource sampleModelsBinding = new BindingSource();
private void RadForm1_Load(object sender, EventArgs e) {
sampleModels.Add(new SampleModel() {
When = DateTime.Parse("1980-04-23"),
SomeText = "Purple Bananas",
IsTrue = true
});
sampleModels.Add(new SampleModel() {
When = DateTime.Parse("2002-07-20"),
SomeText = "Ball & Chain",
IsTrue = false
});
sampleModelsBinding.DataSource = sampleModels;
controlContainingGridView.SetupColumns((grid) => {
grid.AddDateTimeColumn(nameof(SampleModel.When), "When");
grid.AddTextBoxColumn(nameof(SampleModel.SomeText), "Some Text");
grid.AddCheckBoxColumn(nameof(SampleModel.IsTrue), "Is True");
});
controlContainingGridView.DataSource = sampleModelsBinding;
}
Inclusion of the CheckBox column results in the following error:
Exception thrown: 'System.NullReferenceException' in Telerik.WinControls.GridView.dll

Workaround:
private void RadGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
if (e.RowInfo is GridViewSearchRowInfo)
{
e.RowInfo = new MySerachRow(e.ViewInfo);
}
}
{
public MySerachRow(GridViewInfo viewInfo) : base(viewInfo)
{
}
public override string GetCellFormattedValue(GridViewRowInfo row, GridViewColumn column)
{
if (row is GridViewSummaryRowInfo)
{
return "";
}
return base.GetCellFormattedValue(row, column);
}
}
Please refer to the attached gif file. You will notice that for the GridViewMaskBoxColumn with numeric mask the filtering doesn't work. For the other columns each key stroke filters the grid rows.
Workaround: either use a GridViewDecimalColumn or change the default editor for the GridViewMaskBoxColumn :
this.radGridView1.EditorRequired += radGridView1_EditorRequired;
private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
{
if (this.radGridView1.CurrentColumn.HeaderText == "MaskBoxColumn")
{
GridSpinEditor spinEditor = new GridSpinEditor();
RadSpinEditorElement element = spinEditor.EditorElement as RadSpinEditorElement;
element.ShowUpDownButtons = false;
e.Editor = spinEditor;
}
}

RadGridView
NEW
- New property inside GridViewSearchRowInfo: DeferredSearch. Gets or sets a value indicating whether grid will wait until enter key is pressed before it starts a search.
I have implemented this and it is exactly what I want and need, Thank you!
However I thought I might point out that when you tab out it doesn't implement the search, only when you press enter.
And when you press the X to clear the search it clears the text box but not the search. the count of found and the highlighted finds remain
In my gridview need support of different heights of rows. I solved it with the autosize property.
But now I have a side action that the header row and filter row also react to the autosize property.
Attached you can see this behaviour...
Here my code:
Grid.MasterView.TableFilteringRow.MinHeight = 40
Grid.AutoSizeRows = True
Is there a chance to separate data rows from filter and header row?
Regards,
Dimitri
Steps to reproduce:
- Click column header to sort.
- Click button which to export to Excel.
- The rows return to unsorted.
- Scroll down slightly and scroll back up and the sort is restored.
This happens after calling RunExport.
I attached a gif and a sample project.
GridView is not correctly drawn if it's not populated and the theme is set to "TelerikMetro" or "TelerikMetroBlue" (the bottom line is missing).
Steps to reproduce the behavior: create a RadForm, add a RadGridView to it and set the theme to "TelerikMetro" or "TelerikMetroBlue" by using ThemeResolutionService.ApplicationThemeName.
To reproduce:
- Set the AutoSize to true
- Add GroupDescriptor
- An InvalidOperationException is thrown
