    [CLOSED] Combo box set background color code behind

    Hi All,

    There is a method (code behind):
    comboBox.SetVaue(value);
    I need to set a background color as well.
    How can I set background color at the same time as the value?

    Thank you.

    Daniil,

    Thank you for your answer.
    I saw that thread and it provides a client side solution. (if it is not, please, make it clear for me)

    Can I change a color in code-behind?

    Yes, it is a client side solution and there is no a direct code behind counterpart for that.

    I can suggest this solution.

    Example
    <%@ Page Language="C#" %>
    
    <script runat="server">
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!X.IsAjaxRequest)
            {
                Store store = this.ComboBox1.GetStore();
                store.DataSource = new object[] 
                { 
                    new object[] { "1", "Item 1" },
                    new object[] { "2", "Item 2" },
                    new object[] { "3", "Item 3" }
                };
            }
        }
    
        protected void SetYellow(object sender, DirectEventArgs e)
        {
            X.Js.Call("setBackgroundColor", new JRawValue(this.ComboBox1.ClientID), "yellow");
        }
    
        protected void SetGreen(object sender, DirectEventArgs e)
        {
            X.Js.Call("setBackgroundColor", new JRawValue(this.ComboBox1.ClientID), "green");
        }
    </script>
    
    <!DOCTYPE html>
    
    <html>
    <head runat="server">
        <title>Ext.NET v2 Example</title>
    
        <script>
            var setBackgroundColor = function (comboBox, color) {
                comboBox.inputEl.setStyle({
                  "background-image": "none",
                  "background-color": color
                });
            };

                                    <ext:ModelField Name="text" />
                                </Fields>
                            </ext:Model>
                        </Model>
                        <Reader>
                            <ext:ArrayReader />
                        </Reader>
