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

Hi. it was great to see the option "ImageOnly", for columns of small width, where only the image is placed in the header, and the "HederText" property was set, for the correct display of the grouping field

GridViewDataColumn column;

column.HeaderText = "Счет";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;

GridViewDataColumn column;

column.HeaderText = "";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;

it’s impossible to choose one thing, either an ugly header, or a grouping without a description

Hi,

I want to add a MultiComboBoxColumn to a GridView

is it possible to define the columns for this MultiComboBox at design time (in Property Builder editor of Grid) ?

how can i insert , update or delete? i tried after choosing the data source , it shows the data correctly but when i edit or add a new item the database is not affected (allow edit,delete and add row are set to true)

Hi Mostafa,

The end users can copy a single cell even when the SelectionMode is set to FullRowSelect via the ContextMenu when opening it on any of the data cells. If the context menu is opened on the row header they will select the whole row. Please check the attached video: radgridview-context-menu-behavior.gif.

If you would like to copy a single cell using the Ctrl-C command and have the grid setup in FullRowSelect mode please check the attached project featuring a solution. I am also attaching a video showing the result using the custom implementation in the project: radgridview-full-row-ctrl-c.gif

Please refer to the attached screenshot.

Workaround:

public Form1()
{
    InitializeComponent();

    DataTable dt = new DataTable();
    dt.Columns.Add("Id");
    dt.Columns.Add("Name");
    for (int i = 0; i < 5; i++)
    {
        dt.Rows.Add(i, "Item" + i);
    }

    this.radGridView1.DataSource = dt;
    this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

    this.radGridView1.AllowSearchRow = true;
    this.radGridView1.SearchRowPosition = Telerik.WinControls.UI.SystemRowPosition.Bottom;

    this.radGridView1.ViewDefinition = new CustomTableViewDefition();
}

public class CustomTableViewDefition : TableViewDefinition
{
    public override IRowView CreateViewUIElement(GridViewInfo viewInfo)
    {
        return new CustomTableElement();
    }
}

public class CustomTableElement : GridTableElement
{
    protected override RowsContainerElement CreateViewElement()
    {
        return new CustomRowsContainerElement();
    }
}

public class CustomRowsContainerElement : RowsContainerElement
{
    protected override SizeF ArrangeOverride(SizeF finalSize)
    {
        float y = 0;

        this.TopPinnedRows.Arrange(new RectangleF(0, y, finalSize.Width, this.TopPinnedRows.DesiredSize.Height));
        y += this.TopPinnedRows.DesiredSize.Height + ElementSpacing;

        this.ScrollableRows.Arrange(new RectangleF(0, y, finalSize.Width, this.ScrollableRows.DesiredSize.Height));
        y += this.ScrollableRows.DesiredSize.Height + ElementSpacing;

        this.BottomPinnedRows.Arrange(new RectangleF(0, finalSize.Height - this.BottomPinnedRows.DesiredSize.Height,
            finalSize.Width, this.BottomPinnedRows.DesiredSize.Height));

        return finalSize;
    }
}

There should be a convenient and more straightforward API for accessing the TableElement of a child gridview. Currently, the API is:
void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridDetailViewCellElement)
    {
        ((GridDetailViewCellElement)e.CellElement).ChildTableElement.RowHeight = 50;
    }
}

Add an ExportToXlsx option into the native RadGridView exporting.  It has been done for WPF (http://docs.telerik.com/devtools/wpf/controls/radgridview/export/export-xlsx) - why not WinForms.  This would avoid the pain of having to implement the export using RadSpreadProcessing.

For now you can manually add the columns to the ExcelFilteredColumns collection when the filters are added in code:

FilterDescriptor fd = new FilterDescriptor("Value", Telerik.WinControls.Data.FilterOperator.IsEqualTo, "B");
fd.IsFilterEditor = true;
radGridView1.FilterDescriptors.Add(fd);

this.radGridView1.MasterTemplate.ExcelFilteredColumns.Add( this.radGridView1.Columns[0] );   

Synchronization between the filter descriptors collection and the excel like filtering.

There should be a Enum (Left, Right, None) property of the Expander Column indicating whether the position of the expander column should be left right or none.  This would be especially important during pinning activities meaning no matter how many columns are being pinned and repositioned in the pinned area of the grid, it would always remain on the left, right or none.

RadGridView should be able to create new rows using objects with properties matching the FieldNames of the control's columns.

Currently when RadGridView contains multiple header rows and its layout is being saved, after loading it the grid shows "No data to display" although it is binded to a data source. 

Add a functionality to support saving the layout when RadGridView contains multiple header rows

Save\Load functionality of the control should work with ColumnGroupsViewDefinition.

Currently it is not possible to change the table header row height when using column groups view definition.
