    I am using a rad grid. I have added custom template columns dynamically. On template column i am having a custom multiselect combobox (RadComboBox with CheckBox and Label inside ItemTemplate).

    How can i access the combo selected value on post back due to save buton click.
    if possible send me sample solution with dynamically created multiselect ComboBox.

    I am using following code snnipet for custom combobox:

    public class CustomDDLItemTemplate : ITemplate

        ListItemType templateType;
        string ColName = "AppName";

        /// <summary>
        /// Create the template
        /// </summary>
        /// <param name="container"></param>
        public void InstantiateIn(Control container)
            CheckBox checkBox = new CheckBox();
            Label lblDisplayText = new Label();      

            checkBox.ID = "checkBox";
            checkBox.Attributes.Add("onclick", "onCheckBoxClick(this,'"+ container.ClientID +"');");
            lblDisplayText.ID = "label";
            lblDisplayText.DataBinding += new EventHandler(this.Label_DataBind);

            // Create a new HtmlGenericControl.
            HtmlGenericControl NewControl = new HtmlGenericControl("div");

            // Set the properties of the new HtmlGenericControl control.      
            NewControl.Attributes.Add("onclick", "StopPropagation(event);");

            // Add the new HtmlGenericControl to the Controls collection of the PlaceHolder control. 


        public void Label_DataBind(Object sender, EventArgs e)
            Label lbl = (Label)sender;
            RadComboBoxItem radCombo = (RadComboBoxItem)lbl.NamingContainer;     
            lbl.Text = DataBinder.Eval(radCombo.DataItem, ColName).ToString();
