如何在数据网格视图中绑定comboxcell选择的值 [英] how to bind comboxcell selected value in datagridview

问题描述

嗨 我创建了一个combox，并在用户单击
时将其添加到datagridview 特定的单元格组合框将显示在该单元格中.这里的问题是
从combox选择值后，如果我移到下一个单元格，则选择的值
将消失.我要将所选值存储到datagridview单元中.
我的代码是

 公共 ComboBox combobox2 = 新 ComboBox();
私有 无效 hmloadingpage1_Load(对象发​​件人，EventArgs e)
{
   
   combobox2.Hide();
   dataGridView1.Controls.Add(combobox2);

}

私有 无效 dataGridView1_CellDoubleClick(对象发​​件人，DataGridViewCellEventArgs e)
{
   此 .combobox2.Location = 此 .dataGridView1.GetCellDisplayRectangle(e.ColumnIndex，e.RowIndex， true ).位置；
           此 .combobox2.SelectedValue = 此 .dataGridView1.CurrentCell.Value;
           此 .combobox2.Show();
       } 

如果有人知道如何存储所选值，请帮帮我.

解决方案

我使用数据网格的方式是将单元格的属性设置为组合框，然后将内容添加到集合中.我相信您也可以为此使用绑定源.

当用户从组合框中选择时，该值将保持显示.如果需要设置默认值，则需要使用Text属性，然后如果要保存数据，则需要将单元格引用为datagridname.row [index ] .cell [index] .value并将其转换为所需的数据类型.

希望对您有所帮助.

解决方案

Hi,

The way I used the data grid was to set the property of the cell as combo box and add the contents in the collections. I believe you could also use a binding source for this.

When the user select from the combo box the value remains displayed.If you need to set a default value you need to use the Text property and if you then want to save your data you need to refer to the cell as datagridname.row[index].cell[index].value and convert this to your desired datatype if necessary.

I hope this helps.
