RadTextBox issue in IE7

[Wolfgang Sigel]

Hi Telerik,
I'm facing serious problems with a RadTextBox in IE7. The setting of the textbox (in a user control) is as follows:

<telerik:RadTextBox ID="RadTextBoxRollingStock" runat="server" TextMode="MultiLine" Rows="1"
                Label="Name the rolling stock" LabelCssClass="label_inputfield" Width="340px"
                Skin="input_calculator" EnableEmbeddedSkins="False">
 </telerik:RadTextBox>

When I try to run the page the VS debugger comes up displaying (reduced to the part where the problem comes up):

Telerik.Web.UI.RadInputControl.prototype={initialize:function(){Telerik.Web.UI.RadInputControl.callBaseMethod(this,"initialize");
this._clientID=this.get_id();
this._wrapperElementID=this.get_id()+"_wrapper";
this._textBoxElement=$get(this.get_id()+"_text");
this._originalTextBoxCssText=this._textBoxElement.style.cssText;
if(this._originalTextBoxCssText.lastIndexOf(";")!=this._originalTextBoxCssText.length-1){this._originalTextBoxCssText+=";";
}if($telerik.isIE7){var b=$get(this._wrapperElementID);
if(b.style.display=="inline-block"){b.style.display="inline";
b.style.zoom=1;
}

I've debugged these lines and got:

this._clientID   "CalculatorWizard_CalcStep3_RadTextBoxRollingStock"   String
this._wrapperElementID   "CalculatorWizard_CalcStep3_RadTextBoxRollingStock_wrapper"   String
this._textBoxElement   {object}   DispHTMLTextAreaElement
this._originalTextBoxCssText   "WIDTH: 100%;"   String
this._originalTextBoxCssText.lastIndexOf(";")   11   Long
this._originalTextBoxCssText.length-1   11   Long
$telerik.isIE7   true   Boolean
$get(this._wrapperElementID)   null   Object
b   null   Object
b.style.display   Objekt erforderlich   Fehler

So the problem comes up when variable b is used - since it's null at that time. In FireFox this problem doesn't come up. I also don't understand why this problem comes up only with this specific RadTextBox since we're using similar ones with same css, skins, etc
and there is no problem.

Any suggestions what could cause this ?

Thanks, Wolfgang

I found the "source" of the problem: there is an asp:panel before the RadTextBox, and that Panel has its visibility initially set to false.
Setting its visibility to true resolves the problem with the RadTextBox mentioned before. However - I do have a reason to display / not display that panel.

Hello Wolfgang,

$get(this._wrapperElementID) can be null only if there is no HTML element with an ID of this._wrapperElementID on the page. Since such an element exists (this is the wrapper DIV of the RadTextBox control), the error is a little strange and we will need a simple web page in order to track down the exact cause of the problem.

By the way, please validate the page and check for invalid HTML.

Hi Dimo,
how do I upload files to you - doing about 30 - 50 hardcopys is a little cumbersome - for me to do & for you to read ...
