NamedRange.MergeCells Property (2007 System)

Gets or sets a value that indicates whether the NamedRange control contains merged cells.

Namespace:  Microsoft.Office.Tools.Excel
Assembly:  Microsoft.Office.Tools.Excel.v9.0 (in Microsoft.Office.Tools.Excel.v9.0.dll)

[BrowsableAttribute(false)]
public Object MergeCells { get; set; }

Property Value

Type: System.Object
true if the NamedRange control contains merged cells; otherwise, false.

The following code example displays the value of the MergeArea and MergeCells properties of a single-cell NamedRange before and after using the Merge method to merge a multiple-cell NamedRange that contains the single-cell NamedRange.

This example is for a document-level customization.

private void MergeRange()
{
    Microsoft.Office.Tools.Excel.NamedRange namedRange1 =
        this.Controls.AddNamedRange(this.Range["A1", "A5"],
        "namedRange1");

    Microsoft.Office.Tools.Excel.NamedRange namedRange2 =
        this.Controls.AddNamedRange(this.Range["A1", missing],
        "namedRange2");

    string beforeMergeAddress = namedRange2.MergeArea.get_Address(
        missing, missing, Excel.XlReferenceStyle.xlA1, missing, missing);

    MessageBox.Show("Before merging, the MergeArea property is '" +
        beforeMergeAddress + "' and the MergeCells property is " +
        " '" + namedRange2.MergeCells.ToString() + "'.");

    namedRange1.Select();
    namedRange1.Merge(false);

    string afterMergeAddress = namedRange2.MergeArea.get_Address(
        missing, missing, Excel.XlReferenceStyle.xlA1, missing, missing);

    MessageBox.Show("After merging, the MergeArea property is '" +
        afterMergeAddress + "' and the MergeCells property is " +
        " '" + namedRange2.MergeCells.ToString() + "'.");
}
