Hi Prabhjeet,
Sorry for the delay in responding.
I am afraid that I was not able to reproduce the issue that you mentioned here. I have created a simple sample and tested this issue in the following environment windows xp with service pack2, Vs2005, .Netframework 2.0, v6.1.0.34. But it is not reproduced.
Please refer the sample in the below link:
http://websamples.syncfusion.com/samples/Tools.Web/6.1.0.34/F72650/main.htmPlease have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample and send us the modified sample so that we could sort out the cause of the issue and provide you a solution?
Also please provide your system details.
Regards,
G.Yavana
