Use webpart series controls in ASP. NET 2.0 (2)

Next, we will introduce how to use custom controls in the webpart control series.

1. First, we add a "Google. ascx" Control for the project, and add the famous Google logo image under the images directory.

Next, add a 2*2 row table to the form, set it to google.gif, and add a text box and a button, as shown in. The name of the control is in the brackets:



3. Write the following in the Click Event of the btnsearch button: Code :

Response. Write (page. isvalid)
Dim querystr as string = httputility. urlencode (txtsearch. Text)
Response. Redirect ("http://www.google.com/search? Q = "& querystr)
End sub

4. Drag the compiled Google. ascx control to the cell in the middle of the table we just created, as shown in:



Modify the Code as follows:

<Uc1: Google Title = "Google Search" runat = "server" id = "google1"/>

Next, run F5. You can see that Google search is performed in the webpart of googlesearch.

At the same time, if you think that the buttons for webpart close, restore, and minimize are not very nice, you can also customize the buttons, such as adding the following image under the images directory:



Then, you can specify the following attributes in the attributes of webpartzone1.

Closeverb. imageurl = "images/closeverb.gif"
Editverb. imageurl = "images/editverb.gif"
Minimizeverb. imageurl = "images/minimizeverb.gif"
Restoreverb. imageurl = "images/restoreverb.gif"
