refresh gridview on parent form after modal child form closed [modified]

[johland]

hi i've got a gridview on a parent webform. after closing a child form that was opened in modal mode i want the gridview to be refreshed. now i have tried several things that dont work and i dont know why: 1. tried to use: __doPostBack(buttonName,'') in javascript methode but nothing happened. this is the code i have used: code behind:

protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
return;
//btnNewChore:the button that activates the modal dialog
//btnRefresh: the button that shld activate the gridView refreshing

btnNewChore.OnClientClick = "javascript:OpenChild( theURLOfTheChildForm, btnRefresh.ID)";

}

protected void btnRefresh_Click(object sender, EventArgs e)
{
gridViewChores.DataBind();
}

Javascript:

function OpenChild(theURLOfTheChildForm,targetButton)
{

    var winSettings = "center:yes;resizable:no;dialogHeight:300px"
    var returnValue = window.showModalDialog(URL, "", winSettings );
  
        if (returnValue == null)
        {
          window.alert("NO chore was created!");
        }
        else
        {
         \_\_doPostBack(btnName,'');
        }

2.i've also tried to use document.all("btnRefresh").click(); instead of __doPostBack but i've got an error :document.all("... not an object etc... Thank you in advance for your help yohay

I had this same problem. I never found a solution, I ended up using window.redirect('samePage.aspx'); I had used the code in the modal window to save the parameters in session state. Then when the parent page reloaded it used the new parameters to bind the grid.

I didn't get any requirements for the signature

Is the other page that's being opened an aspx page? If it is, you can try declaring an object type of formview in the popups code behind. For ex. FormView fv = new FormView(); fv = (FormView)this.Parent.FindControl("NameOfFormView"); fv.DataBind(); However, I used AJAX's modalpopupextender on an ascx User Control that was on my page, so I hope it will work for you too. There is a possibility Parent may need to be in there more than once depending upon the levels.
