                                                <Editor>
                                                    <ext:ComboBox ID="cmbStation" runat="server" ReadOnly="true" >

                                                </Editor>
                                            </ext:Column>

background code:

   public void BindCombo()
    {
        DataTable dt = DB.Select().From<TStationcharacter>().ExecuteDataSet().Tables[0];
        if (dt.Rows.Count > 0)
        {
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                cmbStation.Items.Add(new Coolite.Ext.Web.ListItem(dt.Rows[i]["C_TYPENAME"].ToString(), dt.Rows[i]["C_ID"].ToString()));
            }
        }

Hi,

It is difficult to say what wrong without full example.
The single wrong thing I saw in your existing code that your column have no DataIndex

thank you everybody.
i try any method,but the combobox can not display Text,it's display value field yet
i used store ,DataTable,DatatSet to bind.fuction is ok,display is wrong.

        //DataTable dt = DB.Select().From<TStationcharacter>().ExecuteDataSet().Tables[0];


        //if (dt.Rows.Count > 0)
        //{
        //    for (int i = 0; i < dt.Rows.Count; i++)
        //    {
        //        cmbName.Items.Add(new Coolite.Ext.Web.ListItem(dt.Rows[i]["C_TYPENAME"].ToString(), dt.Rows[i]["C_ID"].ToString()));
        //        cmbName.SetValueAndFireSelect(dt.Rows[i]["C_TYPENAME"].ToString());
        //    }
        //}
        //DataTable dt2 = DB.Select().From<TLines>().ExecuteDataSet().Tables[0];
        //if (dt2.Rows.Count > 0)
        //{
        //    for (int i = 0; i < dt2.Rows.Count; i++)
        //    {
        //        cmbLineCode.Items.Add(new Coolite.Ext.Web.ListItem(dt2.Rows[i]["L_NAME"].ToString(), dt2.Rows[i]["L_ID"].ToString()));
        //    }
        //}


        storeStation.DataSource = DB.Select().From<TStationcharacter>().ExecuteDataSet();


        storeStation.DataBind();

aspx:

 <ext:Column Header="Station" DataIndex="S_NAME">
                                                <Editor>
                                                    <ext:ComboBox ID="cmbName" runat="server" StoreID="storeStation" DisplayField="C_TYPENAME" ValueField="C_ID">
                                                    </ext:ComboBox>
                                                </Editor>
                                            </ext:Column>

Hi,

Is it a problem for you? Just this non-standard tags using by combo for building template. Just ignore this validation message.
