How to programmatically add a webpart to a page?

Question

I have created a webpart, now I need to add that webpart programmatically into the EditForm.aspx page. Can anyone help me on this.

Answer 1

You can create a feature and on the activation of the feature you can add the webpart to the page.

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    SPSite site = properties.Feature.Parent as SPSite;
    using(SPWeb web = site.OpenWeb())
    {
        using(SPLimitedWebPartManager wpManager = web.GetLimitedWebPartManager(page url, System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared))
        {
            YourWebPart webpart = new YourWebPart();
            webpart.ZoneID = "Top";
            webpart.Title = "My Webpart";
            wpManager.AddWebPart(webpart,"Top" , 0);
        }
    }
}

Hope it helps.

Take a look at the SPLimitedWebPartManager.

Grab the SPFile object related to the EditForm.aspx page and then execute the GetLimitedWebPartManager method on the SPFile object. Use the limited web part manager to modify the web part page.

Answer 4

Here is the method of SPLimitedWebPartManager class which opens the closed web parts

    // Summary:
    //     Opens a dynamic Web Part that was previously closed by CloseWebPart so it
    //     renders on the WebPartPage.
    //
    // Parameters:
    //   webPart:
    public void OpenWebPart(System.Web.UI.WebControls.WebParts.WebPart webPart);

Answer 5

If you don't want to directly reference WebPart type in the code, you can use SPLimitedWebPartManager.ImportWebPart method.

You just need to provide content of the *.dwp or *.webpart description file for the webpart instance you want to import.
