Learn how to setHyperlinkfieldAfter the text of the hyperlink generated by the Data row is learned, the next step is to set the hyperlink goal.URL. If you want to link all hyperlinks to the sameURL, Please directlyNavigateurlSet the property to the requiredURL. Although this setting is the most simple, it is also very impractical. After all, even if it is linked to the same web page, each data column is linked to different locations in the same web page (that is, bookmarks ). -Bookmark). Therefore, what is more practical isDatanavigateurlfieldsAttribute, the reason is very simple. It allows you to specifyURLAs the destination of the Link (Note that the attribute name isSAt the end, there is a mystery. I will explain it later.).

For example, assume that you assignDatanavigateurlfieldsThe attribute fields are not complete.URL(For example:Http://www.gotop.com.twIs only the name of the webpage file (for example:Alexpage. aspx), If you want the hyperlinkURLIf you can add a complete path before the webpage file name, you can write the following code:

 

<Asp: hyperlinkfield datanavigateurlfields = "personal webpage"
Datanavigateurlformatstring = "~ /Members/{0 }"
Headertext = "personal webpage" text = "view personal webpage"/>

 

In the preceding statementRoot directoryBottomMembersWebpage files in the data folder. In terms of the following statement, it means to link to an absoluteURL(That is, a website)MembersWebpage files in the data folder:

 

<Asp: hyperlinkfield
Datanavigateurlfields = "personal webpage"
Datanavigateurlformatstring = "http://www.alexmember.com/members/4100 }"
Headertext = "personal webpage" text = "view personal webpage"/>

Memberpage. aspx? Name = Zhang Limin & memberlevel =
