Hi,

Try adding the " --Select--" text in the Page Load event as shown below.

CS:
 protected void Page_Load(object sender, EventArgs e) 
    { 
        if (!IsPostBack) 
            RadComboBox1.Items[0].Text = "--Select--"
        else 
            RadComboBox1.Items.Remove(0); 
    } 


Thanks
Shinu.

Hello Jun,

You can set the Text property of RadComboBox to "Select". Note that you will need to set the AllowCustomText property to True in addition.

 Hi Veselin,

I have used the Text Property of  RadComboBox to "Select".
It solved my problem.

Now i have another problem. In my form , i have a search function. The search function will fire when the textbox is not empty or when the items in the combobox is selected.

But i found that when i only fill the textbox & not selected the items of combobox. I always get the result for the "first" item of combobox.

How can i set the combobox? if no selected item, then show all the field inside the combobox ( not only the first item in combobox). Thanks.

Hi Jun Ting,

I am afraid I could not understand your logic. Can you please elaborate a bit more?
