组合框短路未将键入的值放在前面

Question

I have two combobox one is product Id and another one is product name. For the both combobox I am assigning same DataTable as datasourse.

My combobox proprieties are follows

cmbprID.DataSource = prdList;
cmbprID.DisplayMember = "PRD_ID";
cmbprID.ValueMember = "PRD_ID";

cmbprName.DataSource = prdList;
cmbprName.DisplayMember = "PRD_NAME";
cmbprName.ValueMember = "PRD_NAME";

and AutoComplete mode=None

 Sorted=false

And now when I run the program all the data loading properly. When I tried to type it is shorting the data but some times some of the data not bring to front. But that data available in drop down.

Following steps I took to solve

• Shorted=true;

For this every thing is working fine. But the problem is, it is not picking product name with respect to PID which I select. The reason is the combobox sorting the data so the index value getting change.

• ORDER BY PRODUCT_ID ASC in my SQL query.

Even this also not working. But it accuracy is better initial stage.

cmbprName.DisplayMember = "PRD_NAME";
cmbprName.ValueMember = "PRD_ID";
cmbprName.Sorted=true;

But no use

Please help me to get of of it

Answer 1

I would use Shorted=true; with ValueMember set with ID rather than same display member. then you can get the selected text and the value from same combobox.

cmbprName.DataSource = prdList;
cmbprName.DisplayMember = "PRD_NAME";
cmbprName.ValueMember = "PRD_ID";
