vb.net DataGridViewComboBoxColumn和下拉样式 [英] vb.net DataGridViewComboBoxColumn and dropdown style

问题描述

在数据网格中，我使用的是其中包含项的组合框，因此用户可以开始键入新值或选择comobo框中存在其他项的项.

问题是当您开始键入并自动使用已经存在的项目填充它时，您按Enter键或向右箭头转到下一个字段，comobobox中的项目将变为空白.

当您回到该领域并再次执行该操作时，它将起作用！我到处搜索，找不到解决方案，有人可以帮忙，我真的很感激.

谢谢

Within a datagrid, I''m using a combo box which has items within it so a user can start typing a new value or select an item that alrerady exists within the comobo box.

The problem is when you start typing and automatically it populates with an item that alread exists and you hit the enter key or right arrow to go to the next field the item within the comobobox goes blank.

When you go back into that field and do it again - it works! I''ve searched everywhere and can''t find a solution to this, can anybody please help, I would really appreciate it.

Thanks
