Good Day All

I have a UserControl in my page. i want to Reload it and refresh it everytime i click a Button, i only want it to be refreshed not the whole page. at the moment i force the postback with the

response.Redirect("mycurrentpage.aspx");

Its working but the Page Flickers a Lot.

Specifically at this page:

Good Morning

I have the Following User Control in the Pic "UserControl_Design_Mode.JPG" and i have the Following code to enable Partial Rendering

UserControl_Design_Mode.JPg

    /*Enabling Partial */

    [DefaultValueAttribute(true)]

    [CategoryAttribute("Behavior")]
    
    public bool EnablePartialRendering { get; set; }

Am exposing the Properties of a usercontrol like like this

    public UpdatePanelUpdateMode UpdateMode
    {

        get
        {
            return this.UpdatePanel1.UpdateMode;
        }
        set
        {
            this.UpdatePanel1.UpdateMode = value;
        }


    }

And there are of them


and i went to the Hosting page we have a pic




for Example, in the Button Remove i have Finally something like this

   Response.Redirect("SubjectStaff.aspx", false); //Refresh the Page again

I was Forcing a Postback and the Whole Page flickers, i want to Refresh only the UserControl.

i tried the Following instead of the above statement



Here am trying to call the name of the usercontrol first and then the Properties it exposes, but i only get the load and load1 event , it seems every is hiden now since i have taken the Control inside the Update Paanel in the User Control.


Can you Help me in that Regard

Thanks

Hey,

To be honest, I haven't really yet played with the UpdatePanel, I simply know about it's existence, and the tutorial I linked to sounded like it would have exactly what you needed. My best guess would be that the UpdatePanel is a Control Container, and as such you will need to use the FindControl method to first locate the control that you want, cast it as the correct type, and then you can access the properties that you have on it.

Hope that helps!!

That is true, it seems after adding the Update panel i could not even use the name of usercontrol to do that as you seen in the pic.

Hey,

I would try the FindControl method and see how you get on. I think this should resolve your issue.

I one concern that I might have is that I don't though enough about the best practices surrounding UpdatePanel and I don't know whether you should be using this method. i.e. should the information you are wanting to add not already exist in the update panel as well.
