Property Value

Returns return value.

Example

The sample below shows you how to display message box before user selecting a row on the grid.
C#Copy Code
WebGrid1.LayoutSettings.ClientSideEvents.OnBeforeRowSelect = "WebGrid1_BeforeRowSelect";
The following is the example of the javascript function that is assigned in above event:
JScriptCopy Code
function WebGrid1_OnBeforeRowSelect(controlId, tblName, lastSelectedObject) 

{ 
   var WebGrid1 = ISGetObject(controlId); 

   alert("The Row is selected") 

   return true; 
}

Remarks

You can specify user-defined Javascript function to respond before a row is selected. The user-defined function should only contain the name of the function. For example, "DoBeforeRowSelect".

The function can be defined in either inline or linked JavaScript files and can accept following parameters:

gridId

The ID of the grid calling the function.

tblName

The Table's Name of the selected row.

lastSelectedObject

The last selected object before the target row is set as current.

Note that you should include the return value of your function. Returning a true value means that default behavior will be processed. Otherwise, the default behavior will be skipped.

Requirements

Target Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family, Windows Vista, Windows Server 2008 family
