Dear Admins.
Using Telerik Winform UI R2 2019 SP1.
I'm trying to add Custom Cell in gridview column. (want to add 2 Buttons and a TextBox)
What i have did is

public class CustomCellElement : GridDataCellElement

{

private RadButtonElement radButtonElement;

private RadButtonElement radButtonElement1;

private RadTextBoxElement radTextBoxElement;

public CustomCellElement(GridViewColumn column, GridRowElement row) : base(column, row)

{

}

protected override void CreateChildElements()

{

base.CreateChildElements();

radButtonElement = new RadButtonElement

{

Text = "-",

Margin = new Padding(1, 1, 2, 1)

};

radButtonElement.Click += new EventHandler(radButtonElement_Click);

this.Children.Add(radButtonElement);

this.radTextBoxElement = new RadTextBoxElement

{

Margin = new Padding(1, 1, 1, 1),

TextAlign = HorizontalAlignment.Right

};

this.Children.Add(radTextBoxElement);

radButtonElement1 = new RadButtonElement

{

Text = "+",

Margin = new Padding(2, 1, 1, 1)

};

radButtonElement1.Click += new EventHandler(radButtonElement1_Click);

this.Children.Add(radButtonElement1);

}

private void radButtonElement_Click(object sender, EventArgs e)

{

int value = Convert.ToInt32(radTextBoxElement.Text) - 1;

if (value > 0)

radTextBoxElement.Text = Convert.ToString(value);

}

private void radButtonElement1_Click(object sender, EventArgs e)

{

int value = Convert.ToInt32(radTextBoxElement.Text) + 1;

if (value > 0)

radTextBoxElement.Text = Convert.ToString(value);

}

protected override void DisposeManagedResources()

{

radButtonElement.Click -= new EventHandler(radButtonElement_Click);

radButtonElement1.Click -= new EventHandler(radButtonElement1_Click);

base.DisposeManagedResources();

}

protected override Type ThemeEffectiveType

{

get

{

return typeof(GridDataCellElement);

}

protected override SizeF ArrangeOverride(SizeF finalSize)

{

if (this.Children.Count == 3)

{

float textBoxWidth = finalSize.Width - radButtonElement.DesiredSize.Width - radButtonElement1.DesiredSize.Width;

RectangleF buttonRect = new RectangleF(0, 0, radButtonElement.DesiredSize.Width, finalSize.Height);

RectangleF textBoxRect = new RectangleF(radButtonElement.DesiredSize.Width - 1, 0, textBoxWidth - 1, finalSize.Height);

RectangleF button1Rect = new

RectangleF(textBoxWidth + radButtonElement.DesiredSize.Width - 1, 0, radButtonElement1.DesiredSize.Width, finalSize.Height);

this.Children[0].Arrange(buttonRect);

this.Children[1].Arrange(textBoxRect);

this.Children[2].Arrange(button1Rect);

}

return finalSize;

}

public class CustomColumn : GridViewDataColumn

{

public CustomColumn() : base()

{ }

public CustomColumn(string fieldName) : base(fieldName)

{

}

public CustomColumn(string uniqueName, string fieldName) : base(uniqueName, fieldName)

{

}

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewDataRowInfo)

{

return typeof(CustomCellElement);

}

return base.GetCellType(row);

}

and How a Add it GridView

CustomColumn customColumn = new CustomColumn

{

Name = "Qty",

FieldName = "Qty",

HeaderText = "Quantity",

Width = 150,

HeaderTextAlignment = ContentAlignment.MiddleRight,

TextAlignment = ContentAlignment.MiddleRight

};

radGridView1.MasterTemplate.Columns.Add(customColumn);

I'm Facing Display problem Please see Image.

Buttons are not displaying properly, cutting the sides. TextBox should be according to the height of GridView cell you can see empty area at the bottom.

How to get and set the value of text box. when row is adding directly to grid.

Please note that the Gridview AllowAddNewRow & AllowEditRow is set to False.(adding Row to GridView Programatically)

But I can Still change the value in the Textbox(Editing to textbox should be disabled.)

Apply the format like other column(please see image).

Thank you

Kashif

RadScheduler header text update

Hi,

I'm trying to update RadSheduler header text to show daily work hours. I'm implementing this from RadScheduler_ActiveViewChanged method, but the text is not changing unless I change active view. How can I resolve this issue?

Thanks for help

Karoon

private void radScheduler1_ActiveViewChanged(object sender, SchedulerViewChangedEventArgs e)
        {
            toolWindow2.Text = e.NewView.ViewType.ToString();

            if (e.NewView is SchedulerDayViewBase)
            {
                SchedulerDayViewBase dayViewBase = (SchedulerDayViewBase)e.NewView;

                dayViewBase.Scheduler.HeaderFormat = "ddd MMM dd";

                UpdateRadSchedulerHeader(dayViewBase);
            }
        }

I'm using the following line in UpdateRadSchedulerHeader method to update text:
((SchedulerHeaderCellElement)dayViewBase.Scheduler.ViewElement.Children[0].Children[j]).Text += "(Time 00:00:00)";

Cell tags lost on LoadLayout

I'm using tags to selectively format cells and using automatic layout saving/loading. When a layout is loaded, cell tags are lost. Example code below. I feel like the cell tag should remain intact and this is a bug? I tried to include a project but only images are allowed on the forum.

Line series not being drawn

My lineseries won't draw the line between points unless I use the category menu to change the palette at run time. I need to define my own palette.

What have I missed, or is this a bug?

Please see extracted solution that shows the problem. I've hand coded all the series etc as messing too much in the designer seems to corrupt the design file.

How i can Move between subitems in Listview Multi columns using tab Key

Normally in radlistview with multi Rows and Columns I can use arrowkey to move between subitems but my intention is to use tab to move faster, I wrote this code but it didn't work (using tabkey to activate arrowkey)
My initial idea was to locate the subitems (via the current column and the current listviewdataitem however I didn't know how to activate the subitems) like using vba to activate a certain cell in excel: Cells ( 1,1) .activate but I haven't found this function yet
Can you tell me can do it or not?
thanks you.
