Hi,

I am using drop down lists in grid view.

I have predefined data in ddl. I am using pagination.

I am in first page. I have some data in ddl. I changed data in ddl and going to second page. If I come back to first page from 2nd page, it is not retaining changed values. It is getting default values.

I want to retain the values after coming back to first page from second page.

It would be great if u can help me out in this regard.

Thank you so much in advance.

You have to maintain the selected value somewhere and show the selected item once again loaded.
Have a look to the following article. It'll help you

Sure you put the dropdown populating code in page IsPostback property. Make sure it is not getting repopulated on every page postback.

This is bit tricky logic.

Every time you move from 1 page to other, the data will get loaded freshly.

Option 1

Save the selected value data of DDL on every page navigation in to the DB.
Onbind you check the saved value and change the selected index of the DDL.

Option 2

Store the selected value in some temporary place and re-use(But home values you can save? If the pages more?)
