Hi Venkat,
Thanks for the reply.You didnot get my problem....actually... i
have a datagrid for which i have been adding ComboBox using
ItemRenderer.The dataprovider for the ComboBox is static one(as you
can see in the above code). When i change any one of the
ComboBox.....and if i move mouse cursor down/up to my datagrid an
vertical scrolling is happening on the datagrid. Just try to execute
the code and you can observe the scroll effect.
Regards,
Malavika.
