How to reload the same page on a button click , with the data from database and ignoring the changes

Question

0.00/5 (No votes)

See more:

I have an aspx page with repeater control on it used for showing the data.The user can modify the data inside the repeater but the data will not get saved until the SAVE button is hit.
I also have an UNDO button on the page. If the user clicks this button, I want to reload the page and discard the changes made by user (similar to UNDO functionality in MS Office)
I need to show him the same data that was shown when the page was loaded for the first time.

Kindly help me with this.

Thank you !

UNDO button is clicked before SAVE or after SAVE

These two buttons are independent. Undo can be clicked any time even before the save is clicked.

Hi,
Keep the data in ViewState that you have already bind to the repeater control.
Track the chages using JavaScript. If user press the undo button compare view state data with the JavaScript recoreded data.

So, You can compare the data and reinstall.But this works for one undo solution not muliple times.

Before SAVE is very Easy
just write following code in ur UNDO click event
Page.Response.Redirect(Page.Request.Url.ToString(), true);

Doing after SAVE is tricky for me sorry for that
