Hi,

We are using Q1 2007 version controls. We are getting problem with combo box in safari browser.

When we try to write some text in editable combo box, safari browser throws unhandled exception (xp, vista OS) and web application gets hanged. While,in Mac OS, browser gets closed for this same scenario.
Error message is: “Safari Web Browser has encountered a problem and needs to close” Also we are not able to track that where problem is occurring. For other browsers (IE 6/7, Fire fox), its working perfectly fine.

My combo box declaration is like this :

radC:RadComboBox ID="ddlUDC1" Skin="Default2006" Height="60px" runat="server" Width="200px" DropDownWidth="187px" meta:resourcekey="ddlUDC1Resource1" SkinsPath="~/RadControls/ComboBox/Skins" MarkFirstMatch="true" >

</radC:RadComboBox>

Please suggest solution for this.
Please note we want to continue with Q1 2007 version only. We do not want to upgrade it.

Any help on this will be appreciated.

Thanks,
Mittal

Hey,
Thanks paul for the reply.

I have seen your live demo and yes its working fine.

But as I have mentioned earlier also, we can’t upgrade our controls. So could you please suggest some workaround for Q1 2007 version controls.

If you can suggest some “patch” or some code we need to add in our controls then also it will be good help for us.

Any help on this, would be great help for us.

Thanks,

Hi Paul,
            As I said earlier also, We cant upgrade our controls.

            But after doing some research and debugging , We have understood that because of following code, safari browser is getting crashed.

            (ComboBox\Scripts\2_8_1\RadComboBox.js)
            RadComboBox.prototype.SetText=function(_5e){
            ....
            this.InputDomElement.value=_5e;

            "_5e" Value is coming blank and its not handled for safari.

            Now we have handled this problem and its working fine.

            Now Our headache is, We have used combo box in almost each page of our web application and in order to get this change in effect, we have to add ' UseEmbeddedScripts ="false" ' in all combox instances. Obliviously, it will be very time consuming and somehow not feasible.

           So can you suggest any way/ solution to get this code in effect with minimal effort.....

Again, I am summarizing the problem,

We have added RadControld folder in our web application.
We have made some changes in ComboBox\Scripts\2_8_1\RadComboBox.js file.
To use this code we have to set UseEmbeddedScripts ="false" property in each control instances.
We have used combo boxes at several places. We have to go and change this property in each instances.

Please let me know what can be best feasible way to fix this.

Thanks,

Hi Mittal,

The easiest solution would be to change the JavaScript source code itself and re-build the control dll. Then you could simply update the dll in your application without modifying any pages.

Another solution would be to inherit from the current version of the control and emit your patched script, overriding the original code (i.e. RadComboBox.prototype.SetText = [your function]). Then again, you could build this new control in a dll and use it across your application.
