Adding WebPart Dynamically - Part-II

In a scenario we have created a CustomWebPart whose .dll is kept in the application Bin folder as per the requirement, now we have to add that webpart at runtime on the activation of a Feature,(so we cannot place that webpart dll in GAC), for this i have followed the following steps:

1.       Open the webPart gallery and click edit on your webpart.

2.      Now Click on "View Xml" .

3.  Copy that XML which looks something like:

@"<?xml version=""1.0"" encoding=""utf-8""?>

<webParts>

<webPart xmlns=""http://schemas.microsoft.com/WebPart/v3"">

<metaData>

<type name=""CustomWebPart, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"" />

<importErrorMessage>Cannot import this Web Part.</importErrorMessage>

</metaData>

<data>

<properties>

<property name=""Title"" type=""string"">CustomWebPart</property>

<property name=""ControlName"" type=""string"">ucSiteSearch.ascx</property>

</properties>

</data>

</webPart>

</webParts>

You can also add your property values as I have added my custom propety value "ControlName" in the XML.

Now the Code snippet:

SPWebPartCollection objWebPartsCollection = objWeb.GetWebPartCollection(URLPage, Microsoft.SharePoint.WebPartPages.Storage.Shared);

string dwp = @"<?xml version=""1.0"" encoding=""utf-8""?>

<webParts>

<webPart xmlns=""http://schemas.microsoft.com/WebPart/v3"">

<metaData>

<type name=""CustomWebPart, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"" />

<importErrorMessage>Cannot import this Web Part.</importErrorMessage>

</metaData>

<data>

<properties>

<property name=""Title"" type=""string"">CustomWebPart</property>

<property name=""ControlName"" type=""string"">ucSiteSearch.ascx</property>

</properties>

</data>

</webPart>

</webParts>";

objWebPartsCollection.Add(dwp);
