Re: Post back in asp button Brij12-Jan-10 23:11 Brij 12-Jan-10 23:11  I think your data is getting removed on every postback so you can put your data in the viewstate and access it as per your requirement.

Re: retrieve current row values from sqldatasource Herman<T>.Instance13-Jan-10 1:57 Herman<T>.Instance 13-Jan-10 1:57  You need the grid to find the data from the source. You have to cast the Object sender in the method to the objecttype desired. I presume it is RadGridRow ( I do not use that object so better chewck your manual) RadGridRow row = (RadGridRow)sender; DataRowView dView = (DataRowView)row.NamingContainer; Normally i use the GridView component and in that case it is: GridViewRow row = (GridViewRow)sender; DataRowView dView = (DataRowView)row.NamingContainer; Good Luck In Word you can only store 2 bytes. That is why I use Writer. Re: retrieve current row values from sqldatasource mary_sa13-Jan-10 7:42 mary_sa 13-Jan-10 7:42  Look I have all data in sqldatasource but don't add all of column in grid it means that I want retrieve Data realty from grid's. How to show Last,Current and Next monts on a calendar control Vinay Babu12-Jan-10 22:05 Vinay Babu 12-Jan-10 22:05  Hello, i had a requirement to show a calender control with Last,Current and Next months with dates at time ( three months dates should be visible) in the calender control view and then provide an option to navigate to other months as it is in the normal calender control. Ideally the control always should show Three Months instead of single month. Please help me on this regard. Thanks, Vinay. Re: How to show Last,Current and Next monts on a calendar control Brij12-Jan-10 22:57 Brij 12-Jan-10 22:57  I had the same requirement earlier.For that ,I used three calendar controls, one for current another for last and next month and was syncing them on server side on any event.So you can follow this approach.

Actually I have made a mail system in any error will come in my application the mail will come to me by which we know about error. this error is comming daily ............ thnks to reply. Re: How To Handele "Invalid viewstate" Error HimaBindu Vejella12-Jan-10 23:56 HimaBindu Vejella 12-Jan-10 23:56  Intresting. make EnableViewStateMac = false and try your luck I think the root casue might be client using Vista and IE8 or IE7 are you not tracking client browser in error log. try to do that that helps in trouble shooting. If you have not checked this . go through it. http://support.microsoft.com/kb/555353[^] iblog: http://himabinduvejella.blogspot.com "If you can dream IT, you can become IT"
