Question

I’m having trouble figuring out something that should be simple but I’m having trouble trying to figure it out.

I have a Page (Default.aspx) which contaiins a WebTab Control (Infragistics, but shouldn’t matter really). Inside each Tab Control of the WebTab is another page, Page1.aspx, Page2.apx, so it’s like this:

Default.aspx
WebTab
    WebTabControl(0)
        Page1.aspx <-- I'm in this codebehind after 
                   calling __doPostBack from JavaScript 
                   as I have a parameter from a WebDataGrid.
    WebTabControl(1)
        Page2.aspx <-- I want to open this page and pass it a parameter.

I’m in Page1.aspx codebehind doing a postback as I have a parameter that I need to pass to the next page, and I want to open Page2.apx which is inside the 2nd Tab.

Basically, I think I need to do the following steps.
1. Set the Active Tab to WebTabControl(1)
2. Give it the Parameter that I have for it to do something with.

I know I’ll have to shoot myself once someone tells how to do it 🙂
Thanks!

Answer 1

Thanks very much for the response, but that’s not what I was looking for.

What I actually did to resolve this problem was to create a JavaScript function in the Default.aspx page that I was able to call from Page1.aspx.

This is the function in the Default.aspx Page, which activated the Tab that I needed and populated the search box with the value I needed from the WebDataGrid from Page1.aspx.

    <script type="text/javascript">
    function activateTab(rowId, tabId) {
        var tab = $find("WebTab1");
        var ctl;
        if (tabId == 3) {
            ctl = window.frames.document.frames[tabId].window.document.getElementById("WebDialogWindow2_tmpl_txtAddressNumber");
        }
        else if (tabId == 2)
            ctl = window.frames.document.frames[tabId].window.document.getElementById("WebDialogWindow2_tmpl_txtAccount");

        if (ctl != null) {            
            ctl.value = rowId;
            tab.set_selectedIndex(tabId, true, null);
            window.frames.document.frames[tabId].window.DoSearch(rowId);
        } 
    }
</script>

I was then able to call the activateTab() function from Page1.aspx with the following function, which is called from the DoubleClick event of the WebDataGrid (I needed to grab a value from the row that was selected.)

        function doubleClickRow() {
        var grid = $find("WebDataGrid1");
        //Get the ADDRESS_NUMBER value.
        var rowId = grid.get_behaviors().get_selection().get_selectedRows().getItem(0).get_cell(2).get_value();
        window.parent.activateTab(rowId, 3);
    }

The next step was to call this JavaScript function on Page2.aspx from the activateTab() function on Default.aspx as shown in the first code example.

        //Force a Postback
    function DoSearch(id) {
        HideSearch();
        __doPostBack("WebDataGrid1", id);
    }

This actually did the post back that I needed so that’s all I had to do. If I wanted to pass those 2 __doPostBack() values into the Page2.aspx Page_Load event, I would have to do the following. However in my case the Post back was all I needed as I had already populated the search box.

            //Don't need these right now, but just in case we might I'll leave them in.
        string eventTarget = Page.Request.Params.Get("__EVENTTARGET");
        string eventArgument = Page.Request.Params.Get("__EVENTARGUMENT");
        Search();

For those who don’t understand the last part with the __EVENT* code, it’s possible if you use a ScriptManager, otherwise you have to code your own Parameters, which I won’t get into here.

That’s all there was to it. I certainly learned some JavaScript along the way here so I hope it’s useful for someone else out there.
