Answer 2

谢谢楼上的几位，不过你们根本没仔细看我的问题。我不是不知道怎样添加ComboBox到DataGrid，我只是在给ComboBox预设SelectedValue初值的时候，不知道为什么语句实效了

Answer 3

lz: 你的要求无非是根据行中某一列的值,动态填充另一列的COMBOX,我这里在VS2005里用DataGridView实现类似的需要,现在给你贴出来,希望对你有所参考:
        private void FillGrid()
        {
            DataGridViewRow dgr = null;
            ArrayList blockArr = (ArrayList)this.Tag;            int count = blockArr.Count;
            int i = 0; string first="";            dataGridView1.RowCount = count;
            try
            {
                foreach (InPutBlock block in blockArr)
                {
                    first = block.ParentDocument.FileName;
                    dgr=dataGridView1.Rows[i];
                    FillRow(first, ref dgr, block);
                    i++;
                }            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }        private void FillRow(string firstCol, ref DataGridViewRow dgr, InPutBlock inputBlock)
        {
            try
            {
                dgr.Cells[0].Value = firstCol;
                dgr.Cells[1].Value = inputBlock.ValName;
                dgr.Cells[2].Value = inputBlock.GetTabName();
                //dgr.Cells[2].Tag = inputBlock.InType;          //将输入端子类型附加到第二个单元格tag上 
                FillCommbox(inputBlock.InType);
                DataGridViewComboBoxCell comCell = (DataGridViewComboBoxCell)dgr.Cells[3];
                comCell.Items.AddRange(nameArr.ToArray());
                if(inputBlock.PinName!="")
                    dgr.Cells[3].Value = inputBlock.PinName;                //dataGridView1.Rows.Add(dgr);
                dgr.Tag = inputBlock;                           //为保存做准备，一行对应一个定值参数
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }        private void FillCommbox(InputType type)
        {
            XmlFile xmlFile = new XmlFile(strResDir);            switch (type)
            {
                case InputType.AI:
                    xmlFile.LoadXml(strResDir + "\\AI.xml");
                    break;
                case InputType.DI:
                    xmlFile.LoadXml(strResDir + "\\DI.xml");
                    break;
                case InputType.FI:
                    xmlFile.LoadXml(strResDir + "\\Frequency.xml");
                    break;
                case InputType.MI:
                    xmlFile.LoadTotalMeasure();
                    break;
                case InputType.YI:
                    xmlFile.LoadXml(strResDir + "\\Pressboard.xml");
                    break;
            }            nameArr =xmlFile.NameArr;
            indexArr = xmlFile.IndexArr;        }

谢谢 sdl2005lyx，可惜我不会2005

Answer 5

我也碰到和你一样的问题，不过我是在2005下，不用DataGridViewComboBoxCell的原因是它没有SelectedValue等事件
