Use attached project to reproduce! Another case is when the font size is changed from the settings dialog - in this case, the row height is not adjusted. Workaround: Use the following custom print style: class MyTableViewDefinitionPrintRenderer : TableViewDefinitionPrintRenderer { public MyTableViewDefinitionPrintRenderer(RadGridView grid) : base(grid) { } protected override int GetDataRowHeight(GridViewRowInfo row, TableViewRowLayoutBase rowLayout) { int result = base.GetDataRowHeight(row, rowLayout); int newHeight = 0; if (!(row is GridViewGroupRowInfo)) { foreach (GridViewColumn col in row.ViewTemplate.Columns) { if (col is GridViewRowHeaderColumn || col is GridViewIndentColumn || !col.IsVisible) { continue; } string value = row.Cells[col.Name].Value.ToString(); TableViewCellArrangeInfo info = ((TableViewRowLayout)rowLayout).LayoutImpl.GetArrangeInfo(col); float cellWidth = (float)info.CachedWidth; int currentHeight = TextRenderer.MeasureText(value, this.GridView.PrintStyle.CellFont, new Size((int)cellWidth, 0), TextFormatFlags.WordBreak).Height + this.GridView.Font.Height *4; newHeight = Math.Max(newHeight, currentHeight); } } return Math.Max(newHeight, result); } } class MyPrintStyle :GridPrintStyle { protected override BaseGridPrintRenderer InitializePrintRenderer(RadGridView grid) { return new MyTableViewDefinitionPrintRenderer(grid); } }
To reproduce: private void RadGridView1_KeyPress(object sender, KeyPressEventArgs e) { int startIndex = radGridView1.CurrentRow.Index +1; for (int i = startIndex; i < radGridView1.Rows.Count; i++) { var value = radGridView1.Rows[i].Cells["Name"].Value.ToString().ToLower(); if (value.StartsWith(e.KeyChar.ToString())) { radGridView1.TableElement.ScrollToRow(radGridView1.Rows[i]); radGridView1.ClearSelection(); radGridView1.Rows[i].IsSelected = true; radGridView1.Rows[i].IsCurrent = true; radGridView1.Columns[1].IsCurrent = true; break; } } } - Press some key so the grid is scrolled down, then press the down key. - The first row is selected instead of the next one. Workaround: remove this line: radGridView1.Rows[i].IsSelected = true;
To reproduce: 1. Run the attached sample project. 2. Right-click the grid. 3. Quickly navigate to another application (e.g. Windows Explorer) before the context menu is shown & wait at windows explorer to display the menu 4. The context will be stuck.
To reproduce: run the attached sample project and you will notice that the top border is missing as it is illustrated in the screenshot. Workaround: set the RadGridView.AutoSizeRows property to false.
To reproduce: public RadForm1() { InitializeComponent(); radGridView1.DataSource = GetTable(); GridViewSummaryItem summaryItem = new GridViewSummaryItem(); summaryItem.Name = "Name"; summaryItem.Aggregate = GridAggregateFunction.Count; GridViewSummaryRowItem summaryRowItem = new GridViewSummaryRowItem(); summaryRowItem.Add(summaryItem); this.radGridView1.SummaryRowsBottom.Add(summaryRowItem); radGridView1.ViewCellFormatting += RadGridView1_ViewCellFormatting; } private void RadGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e) { if (e.CellElement is GridSummaryCellElement) { e.CellElement.DrawFill = true; e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid; e.CellElement.BackColor = Color.Red; } else { e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, Telerik.WinControls.ValueResetFlags.Local); } } protected override void OnLoad(EventArgs e) { base.OnLoad(e); radGridView1.MasterView.SummaryRows[0].PinPosition = PinnedRowPosition.Bottom; } static DataTable GetTable() { DataTable table = new DataTable(); table.Columns.Add("Dosage", typeof(int)); table.Columns.Add("Drug", typeof(string)); table.Columns.Add("Name", typeof(string)); table.Columns.Add("Date", typeof(DateTime)); for (int i = 0; i < 5; i++) { table.Rows.Add(25, "Indocin", "David", DateTime.Now); table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now); table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now); table.Rows.Add(21, "Combivent", "Janet", DateTime.Now); table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now); } return table; } private void radButton1_Click(object sender, EventArgs e) { radGridView1.SaveLayout("test.xml"); } private void radButton2_Click(object sender, EventArgs e) { radGridView1.SummaryRowsBottom.Clear(); radGridView1.SummaryRowsTop.Clear(); radGridView1.LoadLayout("test.xml"); }
To reproduce: this.radGridView1.MultiSelect = true; this.radGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect; radGridView1.ShowRowHeaderColumn = false; Then select the cells in the firs column by dragging the mouse. Workaround: // radGridView1.ShowRowHeaderColumn = false; radGridView1.TableElement.RowHeaderColumnWidth = 0;
Workaround: handle the GridViewPdfExport.CellFormatting event and apply the column`s format string Public Class Form1 Sub New() InitializeComponent() Me.RadGridView1.DataSource = Me.GetData() Me.RadGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill Dim decimalColumn = DirectCast(Me.RadGridView1.Columns("Money"), GridViewDecimalColumn) decimalColumn.DecimalPlaces = 0 decimalColumn.FormatString = "{0:C0}" Dim dateTimeColumn = DirectCast(Me.RadGridView1.Columns("Date"), GridViewDateTimeColumn) dateTimeColumn.FormatString = "{0:D}" End Sub Private Function GetData() As Object Dim dataTable As New DataTable() dataTable.Columns.Add("Id", GetType(Integer)) dataTable.Columns.Add("Name", GetType(String)) dataTable.Columns.Add("Money", GetType(Decimal)) dataTable.Columns.Add("Date", GetType(DateTime)) For i As Integer = 0 To 999 dataTable.Rows.Add(i, "Name " & i, i * 10, DateTime.Now.AddDays(i)) Next Return dataTable End Function Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click Dim pdfExporter = New GridViewPdfExport(Me.RadGridView1) AddHandler pdfExporter.CellFormatting, AddressOf pdfExporter_CellFormatting Dim renderer = New PdfExportRenderer() Dim fileName As String = "..\..\exported-grid.pdf" pdfExporter.RunExport(fileName, renderer) End Sub Private Sub pdfExporter_CellFormatting(sender As Object, e As PdfExportCellFormattingEventArgs) If e.RowIndex > -1 Then e.CellElement.Text = TryCast(RadDataConverter.Instance.Format(e.Row.Cells(e.ColumnIndex).Value, GetType(String), e.Column), String) End If End Sub End Class

To reproduce: please refer to the attached sample project and follow the steps in the provided gif file: 1. Enter something in the search bar 2. Filter on some column, uncheck "All", then select a few items, then validate 3. Click on a random row on the grid 4. Filter on the same column as in 2., check "All", then uncheck a few items, then validate Workaround: private void radGridView1_FilterChanged(object sender, Telerik.WinControls.UI.GridViewCollectionChangedEventArgs e) { this.radGridView1.MasterTemplate.Refresh(); }
To reproduce - Start the attached project press "Add in code" then "Save" - The row is still not added to the underlying data table. Workaround: TryCast(Me.radGridView1.Rows.Last().DataBoundItem, IEditableObject).EndEdit()
Please refer to the attached sample project and gif file illustrating the behavior. ColumnGroupsViewDefinition view = this.radGridView1.ViewDefinition as ColumnGroupsViewDefinition; foreach (GridViewColumnGroup group in view.ColumnGroups) { group.ShowHeader = false; } Workaround: use the ViewCellFormatting and enable the back color for the header cells that are over the hidden group headers public RadForm1() { InitializeComponent(); ColumnGroupsViewDefinition view = this.radGridView1.ViewDefinition as ColumnGroupsViewDefinition ; foreach (GridViewColumnGroup group in view.ColumnGroups) { group.ShowHeader = false; } } private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e) { if (e.Row is GridViewTableHeaderRowInfo && !(e.CellElement is GridColumnGroupCellElement)) { e.CellElement.DrawFill = true; e.CellElement.BackColor = Color.FromArgb(234, 242, 252); e.CellElement.GradientStyle = GradientStyles.Solid; } else { e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local); } }

To reproduce: please refer to the attached gif file and sample project. Workaround: when you set the DrawFill property to true, specify the BackColor to the desired one and reset for the rest of the cells. private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e) { if (e.Column.Name == "ProductName" && e.Row is GridViewDataRowInfo) { if (e.CellElement.Value.ToString().Contains("C")) { e.CellElement.DrawFill = true; e.CellElement.BackColor = Color.Yellow; e.CellElement.GradientStyle = GradientStyles.Solid; e.CellElement.ForeColor = Color.OliveDrab; } else { e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local); } } else { e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local); e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local); } }

To reproduce: please refer to the attached sample project and gif file illustrating the behavior. Add cell value in the new row and press teh down arrow. Workaround: this.radGridView1.MasterTemplate.SelectLastAddedRow = false; This problem is applicable for OpenEdge as well: http://knowledgebase.progress.com/articles/Article/Telerik-RadGridView-highlights-unnecessary-columns-and-rows-in-batch-mode
To reproduce: please refer to the attached sample project and gif file illustrating the behavior. Workaround: in order to cancel adding of the new row, you can call the MasterView.TableAddNewRow.CancelAddNewRow method: private void radGridView1_UserAddingRow(object sender, Telerik.WinControls.UI.GridViewRowCancelEventArgs e) { e.Cancel = true; this.radGridView1.MasterView.TableAddNewRow.CancelAddNewRow(); int index = this.radGridView1.Rows.Count; this.radGridView1.Rows.Add(index, "Row" + index); }
To reproduce: private void MasterTemplate_ViewChanged(object sender, DataViewChangedEventArgs args) { if (args.Action == ViewChangedAction.ExpandedChanged) { } } Workaround: - Use the GroupExpanded event.
To reproduce: - Add default values for all cells in the grid. - Try to add the new row without changing any value. Workaround: private void RadGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e) { var editor = radGridView1.ActiveEditor as BaseInputEditor; var field = editor.GetType().GetField("originalValue", BindingFlags.NonPublic | BindingFlags.Instance); field.SetValue(editor, "asd"); }
To reproduce: - Add DateTime columns to the grid and set the MaskType of the editor to FreeFormDateTime. - Go to the new row enter a valid date and press Tab. Workaround: class Myditor : RadDateTimeEditor { public override bool IsModified { get { return true; } } }
