Release 2024 Q1 (2024.1.130)

When the columns are auto-generated, the way to modify the columns is to use the Columns collection. We could expose an event that will be called when the columns are auto-generating. From the event arguments, we could get the newly created column and replace with if needed or modify it. Similar to the CreateRow event of the control.

Currently, the GridViewCheckBoxColumn is not synchronized with the selection mechanism of the control. Checking a checkbox will change the value of the bound property. Synchronizing the selection with the checkbox will require custom code. We could expose GridViewSelectionColumn or modify the GridViewCheckBoxColumn to support this.

By default, in the Property Builder for GridView, the defaults are:

Header Text Alignment = Middle Center

Text Alignment = Middle Left.

This means that EVERY time I create a new grid, I have to remember to make them both the same.

Why make them different? It makes the grid look rubbish whenthe defaults are used.

Enable the ability to MERGE seperate rows (different records), like found in ITunes "Songs" mode where is shows the artwork (then artist,release undernearth) in a custom class, then the related song rows to the right.

Your competitor Dev Express has it already in place.

Currently, the RadSyntaxEditor control will preserve every change applied to its document. We could expose a mechanism to modify the undo/redo stack or suspend/resume the undo operation, thus allowing us to store only valuable changes.

Release R3 2022 SP2

When you use var, object is assumed. Of course, the object contains a GridViewCellInfo, but you have to cast it first to use one of its members.

The goal is to prevent unnecessary casts.

When you inspect a RadGridView Cell with the inspect.exe tool you will see that the Value property is empty.

Last Updated: 14 Nov 2022 20:41 by ADMIN

In this particular scenario, the RadDropDownListEditor element inside the RadComboBoxColumn cell contains an empty string item. So when we try to clear the value of the cell and leave it empty, the internal logic will return the last selected valid value. The following code demonstrate a simple example:

DataTable dt = new DataTable();
dt.Columns.Add("id", typeof(int));
dt.Columns.Add("codice", typeof(string));
dt.Columns.Add("nome", typeof(string));

dt.Rows.Add(0, "", "");
dt.Rows.Add(1, "I622", "Seravezza");
dt.Rows.Add(2, "G628", "Pietrasanta");
dt.Rows.Add(3, "L833", "Viareggio");

The first row in the DataTable which the RadGridView contains an empty value. If for example, the second row is selected and we use Backspace/Delete to clear the text and move to another cell. The selected item won't be changed. The cell value won't be cleared. To workaround this we could avoid using empty strings. We could use space or some other symbol to allow the user to clear the value from the drop-down popup.

dt.Rows.Add(0, "", "-");
OR
dt.Rows.Add(0, "", " ");

GridViewCellInfo offers Style property which allows you to customize the style for the cells defined at the data cell's level: https://docs.telerik.com/devtools/winforms/controls/gridview/cells/formating-examples/style-property

This functionality should work for the header cells as well like this:

            GridViewCellInfo cell = this.radGridView1.MasterView.TableHeaderRow.Cells[0];
            cell.Style.CustomizeFill = true;
            cell.Style.GradientStyle = GradientStyles.Solid;
            cell.Style.BackColor = System.Drawing.Color.FromArgb(162, 215, 255);

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.

Eery time I use the GridView, I have to remember to un-select the last item in the list.

This is almost always to wrong thing to be selected - so why select it by default?

..and the way to swith this 'feaure' off isn't obvious - I always have to look it up....RadGridView1.CurrentRow = Nothing

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);
            }
        }
