I have checkboxes inside datagridview and when the user selects some checkboxes and click the button the price should be calculated how can i achieve this?

推荐答案

复选框有一个酒店IsChecked属性。您可以使用它来计算您的定价值。 对于那些检查的复选框，您只能为它们执行价格计算。 U可以使用此属性来区分已选中和未选中的复选框。 Checkbox have a property IsChecked property. U can use it to calculate your pricing values. For those check boxes which are check u can perform price calculation for them only. U can use this property to differentiate between check boxes which are checked and which are not.

DataGridView包含DataGridViewRows集合。集合中的每一行都是 DataGridViewRow [ ^ ]。 要获得所选行的总和，您需要遍历行集合： DataGridView contains DataGridViewRows collection. Each row in the collection is DataGridViewRow[^]. To get the total sum of selected rows, you need to iterate through the collection of rows: private void button1_Click(object sender, EventArgs e) { DataGridViewCell dc = null; DataGridViewCheckBoxCell cbx = null; double mySum = 0; string s = string.Empty; foreach (DataGridViewRow dr in dataGridView1.Rows) { dc = dr.Cells[2]; cbx = (DataGridViewCheckBoxCell)dc; if (Convert.ToBoolean(cbx.Value)) { mySum += double.Parse(dr.Cells[0].Value.ToString()); } } s = String.Format("Total sum: {0}", mySum.ToString()); MessageBox.Show(s); } }
