Changing Mode from BrowseDisplayMode to Edit Mode

Question

I have a custom webpart, i am trying to get to do a one-click transition from WebPartManager.BrowseDisplayMode to SPControlMode.Edit. Unfortunately, there is no direct means of transitioning between these two very different modes. But i have built, maybe a successful process but need some help, as the behavior is kind of silly.

So i have a Link Button, with the text "Edit", in the event that the Properties are not set. This situation would be the case where someone comes in and drops the controls on a page and then later on fills in the properties for execution.

Link Button Click event:

void lbtnViewEdit_Click ( object sender , EventArgs e ) {
    if ( WebPartManager.DisplayMode == WebPartManager.BrowseDisplayMode) {
        WebPartManager.DisplayMode = WebPartManager.DesignDisplayMode;
        //SPContext.Current.FormContext.SetFormMode( SPControlMode.Edit , false );
    }
}

And then i started playing with the FormContext DisplayMode settings. Currently it is in the CreateChildControls() event, as i was playing with the event models.

protected override void CreateChildControls () {
    if ( WebPartManager.DisplayMode == WebPartManager.DesignDisplayMode ) {
        SPContext.Current.FormContext.SetFormMode( SPControlMode.Edit , false );
    }

    base.CreateChildControls();
}

The behavior i am currently experiencing, maybe a postback behavior, but i am unsure.

From the BrowseDisplayMode (Published Page), i see the Edit LinkButton. But when i click the Edit button, i have to click it twice to get to the SPControlMode.Edit Mode. The second click of the LinkButton gets me to the display i want to be in, but i would like for it to be a single click transition from a Published Page view to a Edit display, similar to clicking the Edit from the Ribbon.

Any help on which process i should use, would be greatly appreciated.

There is some extra stuff you need to do if you are on a publishing page. This is the JavaScript code I've had success with in the past doing what you are asking:

function ChangeToEditMode(){
    if (window.location.search.match("[?&]PageView=Shared")){
        var inDesignMode = document.forms[MSOWebPartPageFormName].MSOLayout_InDesignMode.value; 

        if (inDesignMode == "1") 
        { 
            // page is in edit mode 
        } 
    }
    else{
        if (document.forms["aspnetForm"]["MSOLayout_InDesignMode"] != null) 
            document.forms["aspnetForm"]["MSOLayout_InDesignMode"].value = 1;
        if (document.forms["aspnetForm"]["MSOAuthoringConsole_FormContext"] != null) 
            document.forms["aspnetForm"]["MSOAuthoringConsole_FormContext"].value = 1;
        if (document.forms["aspnetForm"]["MSOSPWebPartManager_DisplayModeName"] != null) 
            document.forms["aspnetForm"]["MSOSPWebPartManager_DisplayModeName"].value = "Design";
        ChangeLayoutMode(false);                
    }
}

Here was my final implementation without using the JavaScript model to perform the evaluation

if ( WebPartManager.DisplayMode == WebPartManager.BrowseDisplayMode ) {

} else if (WebPartManager.DisplayMode == WebPartManager.DesignDisplayMode) {

}

I do this in my PageLoad, but theoretically you could put this control block anywhere where you need to perform conditional logic based on the current mode the Page/Webpart is in.

Then i overrode some Events:

protected override void CreateChildControls () {
    if ( WebPartManager.DisplayMode == WebPartManager.DesignDisplayMode ) {
        SPContext.Current.FormContext.SetFormMode( SPControlMode.Edit , false );
    }

    base.CreateChildControls();
}
protected override void OnPreRender ( EventArgs e ) {
    if ( ProviderPart != null ) {
        ProviderPart.GetParametersData( new ParametersCallback( SetProviderData ) );
    }

    base.OnPreRender( e );
}
protected override void OnInit ( EventArgs e ) {
    base.OnInit( e );
    InitializeControl();
}
