datagrid combobx问题 [英] datagrid combobx problem

问题描述

这是我的代码

here is my code

if (e.KeyChar == 13)
           {
              panel4.Enabled = false;
           if (dataGridView1.CurrentCell.ColumnIndex == 0)
           {
                    cmb.SelectedIndexChanged += new EventHandler(cmb_SelectedIndexChanged);
                    this.cmb.Location = this.dataGridView1.GetCellDisplayRectangle(0, rowindex, true).Location;

                    this.cmb.Show();
                    this.dataGridView1.Controls.Add(cmb);
                    cmb.Select();
                    cmb.Visible = true;
                    cmb.SelectedIndexChanged += new EventHandler(cmb_SelectedIndexChanged);
                    dgvc = (DataGridViewCell)dataGridView1[dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex];
                    //dgvc.Value = cmb.SelectedText;



           }

当用户输入键时，将弹出一个combobx，但他无法在combobx显示项目上移动光标...任何伙伴都可以告诉我如何移动光标????????

推荐答案

问题是未选择控件.为什么要检查KeyChar而不是Keys枚举?您的代码对我来说似乎很草率，例如，您两次设置了SelectedIndexChanged事件.您意识到控件将以选定的索引开始，并且直到它更改后才会触发?那是你问题的一部分吗?如果必须将Visible设置为true，则应在选择控件之前执行此操作，选择不可见的控件将无济于事.

The issue is that the control is not selected. Why are you checking the KeyChar instead of the Keys enum ? Your code seems very sloppy to me, for example, you set the SelectedIndexChanged event twice. You realise that the control will start with a selected index, and this won''t fire until it changes ? Is that part of your issue ? If you have to set Visible to true at all, then you should do it before making the control selected, selecting an invisible control won''t do anything.
