Hi All,
I am using Infragistics v11.2.20112.2086. I have two text boxes with the NullText property set.
a. The user enters a value in TextBox A
b. clicks a checkbox to copy the value to text box B.
c. When the user then clears text box A, it clears text box B successfully via a javascript function.
postalField.set_text(source.get_text());
However, if step a is skipped, i.e. text bos B is not given a non-blank value initially, then this text box can never be completely blank. If the user enters text in text box A and immediately clears the text in text box A, the text box B is not cleared.
I have confirmed that if If I leave NullText property blank for the text box, this issue does not exist.
I am currently setting the value to " " if it sender.get_text() if it is blank and this seems to fix the issue for now.
Is there any other alternative to solve this problem?
Thanks!
Hello,
I put together a sample to test with that does what I believe you have described above only my sample doesn't work correctly in NetAdvantage 2011 Volume 2 service release 2086 or the latest service release 2225. When testing with NetAdvantage 2012 Volume 2 service release 2121 my sample works as I expect. Does the sample that I have attached demonstrate the issue that you are seeing? If so I recommend upgrading to a later volume of NetAdvantage.
If my sample isn't an accurate representation of what you are doing, please provide me with an example that I can test with so I can make a more appropriate suggestion.
Let me know if you have any questions with this matter.
Hi Viktor and Alan,
Thanks for the reponse. Yes, both your samples are correct. Alan's example with the checkbox is exactly what we are doing.
Thanks for confirming that the issue is fixed in the new version. We will use the temporary fix for now until we upgrade to the next version.
Thanks Alan, this fix solves the issues I have highlighted in this request.
You are a life saver!
I saw that the behavior was different between 11.2.20112.2086 and 12.2.20122.2121 and that the behavior of the 12.2 volume with service release is what you want. I have now done a little more testing and found what is different. It is the implementation of set_value and set_text for the WebTextEditor.
In 11.2.20112.2086 the implementation is:
set_text:function(val){ /// <summary locid="P:J#Infragistics.Web.UI.WebTextEditor.text">Sets text.</summary> /// <param name="val" type="String">Text for control</param> this._setVS(this._text = val); this._repaint(); if(this._fix == 1) this._old = this._instant(true);},set_value:function(val){ /// <summary locid="P:J#Infragistics.Web.UI.WebTextEditor.value">Sets value for control.</summary> /// <param name="val">Value for control. It can be String, Number or Date depending on type of control.</param> this.set_text('' + ((val == null) ? '' : val)); this._fixNull();},
In 12.2.20122.2121 the implementation is:
set_text:function(val){ /// <summary locid="P:J#Infragistics.Web.UI.WebTextEditor.text">Sets text.</summary> /// <param name="val" type="String">Text for control</param> this._setVS(this._text = val = val == null ? '' : val.toString()); this._nullT = !val; this._fixNull(); this._repaint(); if(this._fix == 1) this._old = this._instant(true);},set_value:function(val){ /// <summary locid="P:J#Infragistics.Web.UI.WebTextEditor.value">Sets value for control.</summary> /// <param name="val">Value for control. It can be String, Number or Date depending on type of control.</param> this.set_text('' + ((val == null) ? '' : val));},
You can correct the behavior in my original sample with the version you are using by adding a script after the closing html tag that changes these methods on the prototype for $IG.WebTextEditor:
<script type="text/javascript"> <!-- $IG.WebTextEditor.prototype.set_text = function(val) { /// <summary locid="P:J#Infragistics.Web.UI.WebTextEditor.text">Sets text.</summary> /// <param name="val" type="String">Text for control</param> this._setVS(this._text = val = val == null ? '' : val.toString()); this._nullT = !val; this._fixNull(); this._repaint(); if (this._fix == 1) this._old = this._instant(true); }; $IG.WebTextEditor.set_value = function(val) { /// <summary locid="P:J#Infragistics.Web.UI.WebTextEditor.value">Sets value for control.</summary> /// <param name="val">Value for control. It can be String, Number or Date depending on type of control.</param> this.set_text('' + ((val == null) ? '' : val)); }; // --></script>
Alan,
The issue can clearly be seen in the code below:

Hi Alan,
Thanks for your help. I am using Version=11.2.20112.2086 and not the latest version. Using this version set_value does not work for me, the text editor control B is always blank. My code is
<%@ Register Assembly="Infragistics35.Web.v11.2,Version=11.2.20112.2086 , Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" Namespace="Infragistics.Web.UI.EditorControls" TagPrefix="ig" %>
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <script type="text/javascript"> function changeState() { var editorA = $find("WebTextEditor1"); var editorB = $find("WebTextEditor2"); var copyto = document.getElementById("copyto"); editorB.set_value(editorA.get_value()); editorB.set_enabled(!copyto.checked);
function WebTextEditor1_ValueChanged(sender, eventArgs){ ///<summary> /// ///</summary> ///<param name="sender" type="Infragistics.Web.UI.WebTextEditor"></param> ///<param name="eventArgs" type="Infragistics.Web.UI.TextEditorValueChangedEventArgs"></param> var copyto = document.getElementById("copyto"); if (copyto.checked == true) { var editorB = $find("WebTextEditor2"); editorB.set_value(sender.get_value()); }
I have done some testing with my sample after updating the changeState() function to be:
function changeState() { var editorA = $find("WebTextEditor1"); var editorB = $find("WebTextEditor2"); var copyto = document.getElementById("copyto"); editorB.set_value(editorA.get_value()); editorB.set_enabled(!copyto.checked);}
With this change I don't reproduce the issue that you have. Of if I am I am not looking at it correctly. Please update my sample so that it does reproduce the issue and provide me with the exact steps to duplicate the issue so that I may look into this.
