[Solved] Cell Sizing in Custom Cell

[Phillip]

Hi,

I have a custom cell layout, similar to a Business Card, and it lays out exactly correctly. However I want to instruct the grid to obey a minimum size for the cell, but I cannot seem to get it right.

Heres my code from the custom GridDataCellElement - I wonder if you can spot the problem or sugges a better way of forcing a minumum cell size ?

Thanks.

 protected override void CreateChildElements()
            {
                base.CreateChildElements();
                this.pictureBox = new Telerik.WinControls.UI.RadButtonElement();
                this.pictureBox.MinSize = new Size(150, 150);
                this.pictureBox.Size = this.pictureBox.MinSize;
                this.pictureBox.AutoSize = false;
                this.Children.Add(this.pictureBox);

                this.dataLabelsAndValues = new List<Telerik.WinControls.RadElement>();

                foreach(string propertyName in column.ColumnDefinition.SelectedFields)
                {
                    iSIMS.DataModel.SimpleProperty fieldDefinition = iSIMS.DataEntity.DataEntity.DataModel.GetField<iSIMS.DataModel.SimpleProperty>(propertyName);
                    if (fieldDefinition != null)
                    {
                        Telerik.WinControls.UI.RadLabelElement label = new Telerik.WinControls.UI.RadLabelElement();
                        label.Text = fieldDefinition.Description;
                        label.Font = new Font(label.Font, FontStyle.Bold);
                        label.MinSize = new Size(100, 20);
                        label.Size = label.MinSize;
                        label.AutoSize = false;
                        dataLabelsAndValues.Add(label);

                        Telerik.WinControls.UI.RadLabelElement textBox = new Telerik.WinControls.UI.RadLabelElement();
                        textBox.Tag = propertyName;
                        textBox.AutoSize = false;
                        textBox.MinSize = new Size(100, 20);
                        textBox.Size = textBox.MinSize;
                        dataLabelsAndValues.Add(textBox);
                    }
                }
                this.Children.AddRange(dataLabelsAndValues.ToArray());

            }

            protected override SizeF ArrangeOverride(SizeF finalSize)
            {
                SizeF size = base.ArrangeOverride(finalSize);
                RectangleF clientRect = GetClientRectangle(finalSize);
                int controlOffset = 0;
                int maxWidth = 0;
                int maxHeight = 0;
                foreach (Telerik.WinControls.RadElement element in this.Children)
                {
                    if (element == pictureBox)
                    {
                        element.Arrange(
                            new RectangleF(
                                clientRect.Left+5,
                                clientRect.Top+5,
                                150,
                                150)
                                );
                    }
                    else
                    {

                        element.Arrange(
                            new RectangleF(
                                clientRect.Left + 150 + 5 +5,
                                clientRect.Top + (controlOffset * 20) +5,
                                clientRect.Width - (150 + 5),
                                20)
                                );

                        controlOffset++;
                    }


                }

                return size;
            }

Hello Phillip,

You have to set a minimum height for the row and a minimum width for the column. Please check the following code snippet:

this.radGridView1.Columns["Name"].MinWidth = 150;
this.radGridView1.Columns["Name"].Width = 150;

void radGridView1_CreateRow(object sender, GridViewCreateRowEventArgs e)
{
    if (e.RowInfo is GridViewDataRowInfo)
    {
        e.RowInfo.MinHeight = 150;
        e.RowInfo.Height = 150;
    }
}

Another option is to set the AutoSizeRows property to true and to return your desired size by overriding the MeasureOverride method:

public class MyCell : GridDataCellElement
{
    protected override SizeF MeasureOverride(SizeF availableSize)
    {
        return new Size(100, 100);
    }
}

I hope this helps.
