Setting Focus in ASP.Net

25 Comments

• THis worked and totally rocks!
  

• can u please give me the same in asp.net using visual studio.
  

• Suhasini,
  
  This is .net code. Just define the function setFocus() in your code behind class and then in your OnPageLoad event handler, call this.SetFocus( FieldToSetFocus );

• I put this snippet in an inherited page class, changed ctrl.Id to ctrl.ClientId, and then was able to use it to locate controls inside UserControls. Very handy little script.
  

• I’ve got a page that has user controls (I used flow and not grid) and the user control that needs to have the focus set is the one handling the log in process.
  
  
  
  
  
  
  
  I have changed the ctrl.Id to ctrl.ClientId as one reply suggested, but I do not know how to name the control in the calling line – “me.setfocus(me.txtUserName)” is not working.
  
  
  
  Any help
  

• I have the same problem as Orlando. How can you reference a user control text box from the parent form?
  
  
  
  

• Orlando, I tried this as the parameter and it worked. Just substitute your user control name and field name.
  
  
  
  setFocus(Me.FindControl("UcBatches1:txBatchHeaderCode"))

• Yeh, but. You could do all this with one line of code before .net. (.focus).
  

• I want to have the cursor automatically jump to the next textbox ctrl in a series of textbox ctrls, (i.e. SS#) When my users type in the first 3 numbers, the cursor jumps to the next textbox ctrl and so on. how can this be done?
  
  
  
  A million thanks!

• Orlando,
  
  
  
  Try this for VB.NET:
  
  
  
  Public Sub setFocus(ByVal ctrl As System.Web.UI.Control)
  
  
  
  Dim strS As String
  
  strS = "<SCRIPT language='javascript'>document.getElementById('" + ctrl.ID + "').focus() </SCRIPT>"
  
  Page.RegisterStartupScript("focus", strS)
  
  
  
  End Sub

• Does anyone know how to scroll the page down to the control being focused on? I have a long form with a DropDownList that does an AutoPostback. The drop down generally requires scrolling to reach, so after the postback, the drop down is off the page, even if I have set the focus to the drop down using the above script.

• I have the same problem as Andreas, any suggestions??
  

• pls let me know your answer on this
  

• Andre Andre
  
  
  
  Its realy simple and handy code. I was hunting it from ages.
  

• Jak and Andreas when i used setFocus function with combo box my page scrolls down to corresponding combo . But if u want to save position of scrollbar in postback it can be done in asp.net with SmartNavigation attribute at Page directive. Add it like this--
  
  <%@ Page Language="C#" ClassName="clsSampleMatrix" SmartNavigation=true %>
  
  
  
  and use setFocus for combo. It should solve ur problem.
  

• I'm getting the error that login does not contain a definition for ReqisterStartupScript
