以编程方式设置 DataGridView 中组合框的选定索引 [英] Programmatically set selected index of a ComboBox in DataGridView

问题描述

我想在避免数据绑定的同时，在 DataGridView 的 ComboBox 中设置选定的索引.它没有连接到数据库.

I want to, while avoiding databinding, to set the selected index in a ComboBox in a DataGridView. It is not connected to a DB.

我发现的所有解决方案都将 DataGridView 连接到数据库，但我没有，所以我无法解决问题.

All solutions I have found have the DataGridView connected to a Database, which I have not, so I couldn't solve the problem.

推荐答案

由于 DataGridViewComboBoxColumn 没有 SelectedIndex 或 SelectedValue 属性，您可以尝试像这样设置值:

Since the DataGridViewComboBoxColumn has no SelectedIndex or SelectedValue properties, you can try and set the value like this example:

DataGridViewComboBoxColumn cmbCurrencies = (DataGridViewComboBoxColumn)myDataGridView.Columns["ComboboxCurrencyColumn"];

var currencies = entities.currencies.Select(c => c.currencyName).DefaultIfEmpty().ToList();     

cmbCurrencies.DataSource = currencies; 

然后:

for (int i = 0; i <= myDataGridView.RowCount - 1; i++)
    {
         myDataGridView.Rows[i].Cells["Index of Combobox Column"].Value = "Pound";
    }

另见如果 这个 可能会有所帮助.
