a method to set the title of webpart in code

how to set the title of a webpart without modifying the webpart's property in IE the first time when it is imported and allow user to change the title in IE later by modify the webpart's property. i try many ways ,but the below is one of those, please let me know if anyone find a better way

1. define a public property

string webpartTitle = "WebPlaza Admin";

const string WEB_PART_TITLE = "WebPlaza Admin";

/// <summary>

/// custom web part title

/// </summary>

[Browsable(true),

Category("Miscellaneous"),

DefaultValue(WEB_PART_TITLE),

WebPartStorage(Storage.Personal),

FriendlyName("Custom WebPart Title"),

Description("use this property to set the WebPart Title")]

public string WebPartTitle

{

get

{

return webpartTitle;

}

set

{

webpartTitle = value;

}

}

2. override onPrereder method

protected override void OnPreRender(EventArgs e)

{

this.Title = this.WebPartTitle;

base.OnPreRender (e);

// this.SaveProperties = true;

}

3. override GetToolParts method

public override ToolPart[] GetToolParts()

{

ToolPart[] toolparts = new ToolPart[2];

WebPartToolPart wptp = new WebPartToolPart();

CustomPropertyToolPart custom = new CustomPropertyToolPart();

toolparts[0] = wptp;

hide the default title property

wptp.Hide(Microsoft.SharePoint.WebPartPages.WebPartToolPart.Properties.Title);

toolparts[1] = custom;

return toolparts;

}
