RadGridview Excel filter box has tiny elements

Hi all-

I'm using a RadGridview (Telerik Winforms version 2018.1.220.40) and am having trouble getting the excel filter grid to look right. The radGridView seems to default to Seguoi 8.5 font, but I increased that to 14 to make it readable. The problem I'm having is that, after I enable Excel filtering, when a user chooses to filter, the excel filter box is tiny (I think it's still 8.5 font) - all the checkboxes are tiny, and the titles are unreadable.

I've searched the forums and found some related posts that instruct in (c#) to run through the elements in the viewCellEditing event, but, either I haven't translated them right into VB, or they aren't doing what I expected.

Restricting focus to specific dock window

Hi,

The scenario is following

The system has 2 different windows (type floating.).

Say user is doing something like editing in a first window.

I want programatically to restrict user to the window he is currently working in, until he commits his work.

I.e. prevent him to go to window #2 until he clicks save - so it should work as a modal dialog box while user in editing mode.

I tried to hook up to ActiveWindowChanging event of RadDock class.

I wrote essentially

private void DockerContainer_ActiveWindowChanging(object sender, DockWindowCancelEventArgs e)
{
// some processng
if (needTo capture)
{
e.Cancel = true;
}
}

But it doesn't work.

Are there any way to do what i want to do?

Please help,

Boris Pitel

ColumnGroupsView height

Sample code below. Just copy, paste and run. :)

var grid = new RadGridView

{

Dock = DockStyle.Fill,

AutoSizeRows = false,

AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill

};

grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column1", HeaderText = "Column 1" });

grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column2", HeaderText = "Column 2" });

grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column3", HeaderText = "Column 3" });

grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column4", HeaderText = "Column 4" });

var columnGroupsView = new ColumnGroupsViewDefinition();

columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup("Group 1 Line 1" + Environment.NewLine + "Group 1 Line 2"));

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows.Add(new GridViewColumnGroupRow());

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column1");

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column2");

columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup("Group 2 Line 1" + Environment.NewLine + "Group 2 Line 2"));

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows.Add(new GridViewColumnGroupRow());

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column3");

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column4");

grid.ViewDefinition = columnGroupsView;

var form = new RadForm();

form.Controls.Add(grid);

form.ShowDialog();

How to change by code height of group row? Please see attached image.

Important: I want to stay with AutoSizeRows = false.

RadTextBoxControl custom block

It looks like the stand text block formatting is done on word boundary, i.e. text delimited by spaces. Is there any way to make a custom block so I can format based on words delimited by other characters, e.g. "|", "[", "]" etc. Also, what is the extent of customisation, is it just fore/back colour of text? I'd like bold, italics etc. also so perhaps my best option is to use a rich text editor.

Can't open property builder

I'm having a very strange issue. When I click "open property builder" I am presented with an error message. It says...

Could not load file or assembly 'Telerik.WinControls.Themes.HighContrastBlack, Version ...' or one of its dependencies. The system cannot find the file specified.

What's most interesting is that I am not using or referencing this theme anywhere in my project.

Change color or border a one header column

I'm trying to highlight just one column header.
I would also like the whole column to have a different border to the others.
But I have not managed to modify any element of the header either.
This is the code I am using:

Private Sub RadGridView1_CellFormatting(sender As Object, e As UI.CellFormattingEventArgs) Handles RadGridView1.CellFormatting

If TypeOf e.CellElement Is GridHeaderCellElement Then

e.CellElement.Font = myCustomFont

e.CellElement.BorderBoxStyle = BorderBoxStyle.OuterInnerBorders

End If

End Sub

Thanks!

Custom RowPaint does not work in Print event

I'm using RowPaint event to "merge" cells. But when Printing it is not using the RowPaint event.

I tried to use PrintCellPaint event. But Row of event args are different. One is GridDataRowElement and other is GridViewDataRowInfo.

How can I use the same code to both events?

private void radGridView2_RowPaint(object sender, GridViewRowPaintEventArgs e)

{

var dataRow = e.Row as GridDataRowElement;

if (dataRow == null)

return;

var value = Convert.ToInt32(dataRow.RowInfo.Cells["Group"].Value);

if (value == -1)

return;

var startCell = e.Row.VisualCells[2];

var leftPos = startCell.PointToControl(startCell.Bounds.Location).X + (startCell.TableElement.CellSpacing * startCell.ColumnIndex);

var msgLocation = new Rectangle(leftPos + 1, 1, e.Row.Bounds.Width - leftPos - 2, e.Row.Bounds.Height - 2);

e.Graphics.FillRectangle(new SolidBrush(Color.White), msgLocation);

e.Graphics.DrawString(EventLogs[value], e.Row.Font, new SolidBrush(Color.Black), msgLocation);

var textSize = e.Graphics.MeasureString(EventLogs[value], e.Row.Font, msgLocation.Width);

//if (textSize.Height > dataRow.Size.Height)

startCell.RowInfo.Height = (int)textSize.Height;

}
