我有以下代码的麻烦.当我使用调试器,我得到一个例外,当涉及到以下行：
dgvCalls.Columns.Insert(1,msisnnColumn);
我得到一个例外：
Column cannot be added because its
CellType property is null.
奇怪的是,我为一些其他DataGridView创建了相同的过程,它工作正常.
if (!(dgvCalls.Columns.Contains("DirectionImage")))
{
directionIconColumn = new DataGridViewImageColumn();
directionIconColumn.Name = "DirectionImage";
directionIconColumn.HeaderText = "";
dgvCalls.Columns.Insert(0,directionIconColumn);
directionIconColumn.CellTemplate = new DataGridViewImageCell();
}
if (!(dgvCalls.Columns.Contains("msisndColumn")))
{
msisnnColumn = new DataGridViewColumn();
msisnnColumn.Name = "msisndColumn";
msisnnColumn.HeaderText = "Klic";
dgvCalls.Columns.Insert(1,msisnnColumn);
msisnnColumn.CellTemplate = new DataGridViewTextBoxCell();
}
有什么建议么？
解决方法
dgvCalls.Columns.Insert(1,msisnnColumn); msisnnColumn.CellTemplate = new DataGridViewTextBoxCell();
尝试翻转这两行.这可能会做到这一点.
