I want to choose columns by checkboxes, something like this:
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.

Excel-like pop-up location is not scaled properly on High DPI.
Steps to recreate:
- click on the button on the top row
- press the down key on the keyboard
- Press Space key to select new button, the button on the top row is clicked
The EnableHotTracking property works only in the first level hierarchy. The lower levels still get highlighted.
In the following scenario, we have enabled the pager functionality of the control. If we move to a different page and then set the DataSource to Null, the page index will not be reset.
With releasing .NET 6, there are TimeOnly and DateOnly types which would be more appropriate for managing such values:
https://devblogs.microsoft.com/dotnet/date-time-and-time-zone-enhancements-in-net-6/
It would be good to add support for these types in GridViewDateTimeView.
Currently, the following code gives an exception when entering edit mode:
public RadForm1()
{
InitializeComponent();
DataTable dt = new DataTable();
dt.Columns.Add("DateOnly", typeof(DateOnly));
dt.Rows.Add(new DateOnly(2022,3,3));
this.radGridView1.AutoGenerateColumns = false;
GridViewDateTimeColumn dateColumn = new GridViewDateTimeColumn();
dateColumn.FieldName = "DateOnly";
this.radGridView1.Columns.Add(dateColumn);
this.radGridView1.DataSource = dt;
this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
}
Workaround: you can use the following custom TypeConverter:
public RadForm1()
{
InitializeComponent();
DataTable dt = new DataTable();
dt.Columns.Add("DateOnly", typeof(DateOnly));
dt.Rows.Add(new DateOnly(2022,3,3));
this.radGridView1.AutoGenerateColumns = false;
GridViewDateTimeColumn dateColumn = new GridViewDateTimeColumn();
dateColumn.DataType = typeof(DateTime);
dateColumn.FieldName = "DateOnly";
dateColumn.Format = DateTimePickerFormat.Custom;
dateColumn.CustomFormat = "dd/MM/yyyy";
dateColumn.FormatString = "{0:dd/MM/yyyy}";
dateColumn.DataTypeConverter = new DateOnlyConverter();
this.radGridView1.Columns.Add(dateColumn);
this.radGridView1.DataSource = dt;
this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
}
public class DateOnlyConverter : TypeConverter
{
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
return destinationType == typeof(DateTime);
}
public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
{
if (value is DateOnly && destinationType == typeof(DateTime))
{
DateOnly date = (DateOnly)value;
return new DateTime(date.Year, date.Month, date.Day);
}
return base.ConvertTo(context, culture, value, destinationType);
}
public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
{
return sourceType == typeof(DateTime) ;
}
public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
{
if (value is DateTime)
{
DateTime date = (DateTime)value;
return new DateOnly(date.Year, date.Month, date.Day);
}
return base.ConvertFrom(context, culture, value);
}
}
