从选定的combox获取价值并将其放在文本框c＃中

Question

Mabuhay!

Hi! I search this code here but unfortunately didnt get what I am looking for. Any help on this?

I got this form and have a combo box which i uses dataset so I can get the value of description on this table. And I have a textbox after that but I wanted to get the value of labor cost based on what I selected on combo box.

heres for my combobox

 private void Form1_Load(object sender, EventArgs e)
 {
     // TODO: This line of code loads data into the '_10daliriPayrollDataSet.Description' table. You can move, or remove it, as needed.
     this.descriptionTableAdapter.Fill(this._10daliriPayrollDataSet.Description);
 }

for my laborcost.Text value

private void description_SelectedIndexChanged(object sender, EventArgs e)
{
    laborcost.Text = description.SelectedItem.ToString();
}

I got this error;

System.Data.DataRowView

Any help on this?

Thanks, Chris

Answer 1

try

description.SelectedItem.Text this will do

Answer 2

尝试这个，

description.SelectedValue.ToString();

Answer 3

The correct way of retrieving the item text is the GetItemText method.

It works for any item, including the selected one. The later can be retrieved from the SelectedItem property.

In your case

laborcost.Text = description.GetItemText(description.SelectedItem);

Please note that SelectedText and SelectedValue properties (suggested by some commenters) have different semantics and cannot be used for this purpose.

Answer 4

You need to define DataValue member and Text Member field on your combobox. Its binding with DataRowView.

So just add two line after this.descriptionTableAdapter.Fill(this._10daliriPayrollDataSet.Description);
