Similar to tabpanel's ._hide() function, how can this be implemented in C#?

Even though I feel like I've tackled this issue in the past, I can't seem to locate a resolution anywhere...

In my situation, there are 3 tabs within an ajax TabContainer and two CheckBoxes located outside of it. All 3 tabs are visible unless both CheckBoxes remain unchecked - at that point, the 3rd tab should be hidden.

I have managed to show/hide using javascript whenever the checkbox values change:

    $find('<%=OptionsTabs.ClientID%>').get_tabs()[2]._hide();
    $find('<%=OptionsTabs.ClientID%>').get_tabs()[2]._show();

Yet, during PageLoad, I'm struggling to achieve similar results with C#. I attempted adjusting display and visibility properties, only to find that the tab remained visible. The only method that successfully hid the tab was setting Visible=false, but doing so prevented the tab from being rendered at all and thus couldn't be shown via javascript later on.

UPDATE: I tested embedding the same script during PageLoad, still without success.

    string script = "<script type=text/javascript> $find('<%=OptionsTabs.ClientID%>').get_tabs()[2]._hide(); </script>";

    ClientScriptManager cs = Page.ClientScript;
    String csname1 = "TabScript";
    Type cstype = this.GetType();
    cs.RegisterStartupScript(cstype, csname1, script);

The issue lies in OptionsTabs being null at this point.

I experimented by passing the ClientID obtained server-side. I tried substituting the tab name for the tab container name. I also attempted modifying the display/visibility properties of the tab and its header. Unfortunately, none of these approaches yielded positive outcomes.

Answer №1

Here is a suggested code snippet:

string script = "$find('" + OptionsTabs.ClientID + "').get_tabs()[2]._hide();";
ClientScriptManager cs = Page.ClientScript;
String csname1 = "TabScript";
Type cstype = this.GetType();
cs.RegisterStartupScript(cstype, csname1, script, true);

Alternatively, if you are utilizing MS Ajax with client-side page lifecycle features, you can experiment with using the JavaScript Load event. Include the following code in your client-side script:

Sys.Application.add_load(appLoaded);

function appLoaded(sender, eventArgs) {
   $find('<%=OptionsTabs.ClientID%>').get_tabs()[2]._hide();
}
