推荐答案

大家好， 我假设你已经实现了IDataGridViewEditingControl来托管T DataGridView控件中的extbox。所以在这种情况下你也可能也派生了TextBox控件。 你只需要覆盖On TextChanged事件并解析文本。它会给你更新的价值。 请参考下面的代码块。 Hi All, I assume that you have implemented the IDataGridViewEditingControl to host the Textbox inside the DataGridView control. so in that case you might have also derived the TextBox control as well. You just need to override On TextChanged event and parse the text. it will give you updated vlaue. Please refer the below code block. protected override void OnTextChanged(EventArgs e) { base.OnTextChanged(e); DataGridViewColumn dataGridViewColumn = this.dataGridView.Columns[this.dataGridView.CurrentCell.ColumnIndex]; ISwitchRowStatement swtRowStatement = this.dataGridView["ColRow", this.dataGridView.CurrentCell.RowIndex].Tag as ISwitchRowStatement; float value; if (float.TryParse(this.Text, out value)) { this.dataGridView["ColumnHystersis", this.dataGridView.CurrentCell.RowIndex].Value = value; } }

如果以上解决方案不是，请发布代码为你工作。 问候， Sathish
