Attributes["onchange"]

[sangramkp]

Hi, I am using Dunda's Charts in my asp.net application. I want to refresh two charts on selectedindexchanged event of a dropdown ddlmovie. I have written the code: if (!IsPostBack) { ScriptManager1.RegisterAsyncPostBackControl(ddlMovie); ddlMovie.Attributes["onchange"] = Chart1.CallbackManager.GetCallbackEventReference("ddlMovie", "NA"); ddlMovie.Attributes["onchange"] = Chart2.CallbackManager.GetCallbackEventReference("ddlMovie", "NA"); } But it refreshes the chart2 only.. i want to refresh both the charts... Any solution... :rose:

it is because the way you arr adding onchange (only second onchange will occur) try this if (!IsPostBack) { ScriptManager1.RegisterAsyncPostBackControl(ddlMovie); ddlMovie.Attributes["onchange"] = refreshCharts(); } private void refreshCharts() { Chart1.CallbackManager.GetCallbackEventReference("ddlMovie", "NA"); Chart2.CallbackManager.GetCallbackEventReference("ddlMovie", "NA"); }
