Persist RadWindow in between postback

[Ambuj]

Hi,

I am using Radgrid, I have a colum with the html link upon clicking on that we are opening a radwindow , I have to preserve the rad windows even when the parent Radgrid refreshes ( Postback), I am using asp.net timer control to refresh the grid at a particular interval, as soon as the grid refreshes the windows disappear , Please suggest me how can I preserve the rad window during postback..

we are using DLL version of  2009.1.311.35.

I have done the below code to achieve that.

protected override object SaveViewState()
        {
            Control windowsManager = ctlVariables.FindControl("listPopupManager");
            Control windows = windowsManager.FindControl("variableValue");
            Object basestate =  base.SaveViewState();
            object[] allStates = new object[10];

            allStates[0] = windows.Visible;
            return allStates;
        }

        protected override void LoadViewState(object savedState)
        {
            if (savedState != null)
            {
                object[] myState = (object[])savedState;
                if (myState[0] != null)
                {
                    string visible = myState[1].ToString();
                }
            }

Thanks,

Hello Ambuj,

One approach is to set the VisibleOnPgeLoad property to true based on the scenario. Another approach is to Show the RadWindow through registering a script from the server on refreshing the page.

Can you please give some example on that?

Hello Ambuj,
Try the following approach.

protected void Page_Load(object sender, EventArgs e)
  {
        if (Session["WindowOpend"] == "true")
        {
         //set the visibleonpageload property here
        //  or calluse the RegisterStartUpScript to open the window.
        }
  }
protected override object SaveViewState()
   {
         . . . . . . .
         session["windowopened"]=true;
         return allStates;
    }

Thanks,
Shinu.
