How to lock combobox for typing

开发者_如何学运维I use DevExpress 2.4 and I have a combobox which is bound to a row in a propertygrid control. I want to disable this combobox for editing it content by keyboard and be able only to choose the value by clicking with the mouse. I read on the internet just to change the DropDownStyle property to DropDownList, instead of DropDown but when I go to the combobox in properties I don't have property DropDownList and only DropDownItemHeight and DropDownRows... So how to disable typing in this combobox?

---

Open property editor for this GridControl and open repository, now in options of this ComboBox go down to TextEditStyle and choose DisableTextEditor as option.

---

Just do this: this.comboBoxType.DropDownStyle = ComboBoxStyle.DropDownList;

---

How about using the LookupEdit control?

---

the point about setting the DropDownStyle they have told you is right for standard .NET Framework windows forms DropDowsLists, the DevExpress one you are using is a different control which offers a much richer API and feature set.

I have used the XtraEditors very much in the past and I was always able to get what I needed, can't remember now the exact property name but surely there is a property to do what you need now, not exposed to the main control, try to check the properties of the current editor in your combo box.

In VB.NET, we do as :

    ComboBoxEdit1.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.DisableTextEditor 

I hope there will be similar for C#.NET.

Grid Control Repository Item has its own properties. You could view it by

Run Designer -> Repository -> In-place Editor Repository

Select the item you wish to edit the property. Explore those properties and you would love the manipulation of the properties.

BTW, just change the TextEditStyle property to DisableTextEditor.

Enjoy!
