As it’s a well known issue that after being firefox version 3.6 the Infragistic UltraWebGrid does not behaves correctly i.e we can’t able to edit the grid.

This issue exists in the “ig_Wedgrid.js” file inside the function “igtbl_getAbsBounds”. This is the inbuilt file of the Infragistic to support grid functionality

To fix this issue i have been following the solution provided in the following link:http://blogs.infragistics.com/forums/p/37295/218919.aspx

I.e to replace     else if (ig_csom.IsFireFox && document.getBoxObjectFor (elem)) with else if (ig_csom.IsFireFox && document.getBoxObjectFor)

Now in my project, I have created my own user control i.e UXGrid derived from UltraWebGrid

 public class UXGrid:UltraWebGrid

So in the OnPreRender event I am registering

System.Web.UI.ScriptManager scriptManager1 = ystem.Web.UI.ScriptManager.GetCurrent(Page);

scriptManager1.Scripts.Add(new System.Web.UI.ScriptReference("~/Javascript/ig_WebGrid.js"));

Where ig_WebGrid.js present in the “JavaScript” folder containing the correct above mentioned changes

This fixes the issue of the Grid and Now the Grid become editable and works fine for me.

However I am facing the Issue in the WebCombo control.

As we know that WebCombo is as well internally using the UltraWebGrid, So I am facing the same issue i.e I can’t able to select any item present inside the WebCombo in the Firefox browser after version 3.6.

Same as above I have my own user control created in my project derived from WebCombo as below:

public class UXWebCombo : WebCombo

However in the same way when I am trying to register the JavaScript as below:

System.Web.UI.ScriptManager scriptManager1 = System.Web.UI.ScriptManager.GetCurrent(Page);

scriptManager1.Scripts.Add(new System.Web.UI.ScriptReference("~/Javascript/ig_WebGrid.js"));

this.Columns.Band.Grid.JavaScriptFileName = this.Page.ResolveUrl("~/Javascript/ig_WebGrid.js");

This does not worked for me. However when I am using the above code as below:

System.Web.UI.ScriptManager scriptManager1 = System.Web.UI.ScriptManager.GetCurrent(Page);

scriptManager1.Scripts.Add(new System.Web.UI.ScriptReference("~/Javascript/ig_WebGrid.js"));

this.Columns.Band.Grid.JavaScriptFileNameCommon = this.Page.ResolveUrl("~/Javascript/ig_WebGrid.js");

This Worked for me.

So I want to understand why this is happening and what is the exact difference between the “JavaScriptFileName” and “JavaScriptFileNameCommon” Property and is what I am doing seems correct for your side.
