Steps to reproduce:

1. Bind RadGridView to BindingList 

2. Clear the rows collection

3. You can see that SelectedRows.Count =1 although Rows.Count = 0

To workaround:

private void radButton1_Click(object sender, EventArgs e)
        {  
            while (this.pedidos.Count > 0)
            {
                this.pedidos.RemoveAt(0);
            }

            int rows = this.radGridView1.Rows.Count;
            int srows = this.radGridView1.SelectedRows.Count;

        }

Hello,

I am using a radGridView on a Windows touch screen. When I am trying to scroll the rows by hand (EnableKineticScrolling was set to true), the scrolling process is very slow. If I will use the vertical scrollbar, then it is ok. How can I achieve this without using the vertical scrollbar?

I used EnableFastScrolling=true, but I did not see any improvement.

 

Regards,

Yannis

I was creating a table with filters when I noticed that there is an option in the filters for 'EndsWith' but not one for 'DoesNotEndWith'. We use internal part numbers for our products where the last 3 digits determine the department in which the product was made. Because wildcards cannot be used within the RadGridView filters, I am having to create a unusual workaround. The same can be said about 'DoesNotBeginWith'.

Hi,

when I select the column chooser multiple times via context menu, the column chooser dialog scales multiple times.

Reproduced here with the Telerik sample application. 150 % dpi scaling.

I'm just starting with RadGridView and trying to figure out how to create a combobox column inside my RadGridView.  I've added a column that is of type GridViewComboBoxColumn.  I've created a BindingSource that Contains the values for the combobox.  I can't figure out how to set the datasource property of the Column to use that BindingSource.  Google search says to set the datasource property but when I'm going through the "Open Properties Builder"  and I select my combobox column I don't see that property listed under advanced for the column.

Thanks

Lee

If you want to use Conditional Formatting via code (expression based formatting) you will see that it throws an exception if you set TRIM() condition.

ExpressionFormattingObject expressionCondition = new ExpressionFormattingObject(
expressionCondition.Expression = "TRIM(ContactName) = 'Maria Anders'";
expressionCondition.CellBackColor = Color.Aqua;
this.radGridView1.Columns["CustomerID"].ConditionalFormattingObjectList.Add(expressionCondition);

There is no exception if you use the same condition via "Conditional Formatting Rules Manager" form.

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;
            }
        }

It seems that the GridViewColumnGroup.MinHeight has a big influence on the height of the filter cell.

Workaround:

this.radGridView1.AutoSizeRows = true;

Please refer to the following code snippet demonstrating how the comparer can be applied:

        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.EnableFiltering = true;
            this.radGridView1.ShowHeaderCellButtons = true;
            this.radGridView1.FilterPopupInitialized += radGridView1_FilterPopupInitialized; 
        }

        private void radGridView1_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
        {
            RadListFilterPopup popup = e.FilterPopup as RadListFilterPopup;
            if (popup != null)
            { 
                popup.MenuTreeElement.TreeView.TreeViewElement.Comparer = new MyComparer(popup.MenuTreeElement.TreeView.TreeViewElement);
            }
        }

        class MyComparer : TreeNodeComparer
        {
            public MyComparer(RadTreeViewElement treeView)
                : base(treeView)
            {
            }
            public override int Compare(RadTreeNode x, RadTreeNode y)
            {
                if (this.TreeViewElement.SortOrder == SortOrder.Descending)
                {
                    return x.Text.CompareTo(y.Text);
                }
                return x.Text.CompareTo(y.Text) * -1;
            }
        }

I am currently working in Telerik v2019.3.917 and .Net 4.5.2. I have multiple theme's setup for a local application for my users but I am seeing something odd with the Telerik.WinControls.Themes.HighContrastBlack theme. It appears that I am unable to select more than one cell in this theme. My grid has multiselect as true and SelectionMode as CellSelect. I have tried holding ctrl and clicking cells, clicking the row header, holding the mouse down and dragging, and using Ctrl+A but none of these select more than one cell.

I am setting the application theme on launch:

var _t = new Telerik.WinControls.Themes.HighContrastBlackTheme();
ThemeResolutionService.ApplicationThemeName = "HighContrastBlack";

 

Themes that work: All Fluents, All Material, All VS.

Is this a bug or am I missing something?

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.

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.

Add a new DeferredFilter property on RadGridView level which controls whether the filtering logic will be immediately preformed on each key stroke or only by pressing Enter.

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

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.
