Rowupdating oldvalues empty

Rated 4.94/5 based on 835 customer reviews

I too have been searching for this and all the "answers" that I've seen are not the answers I think some of us are really looking for.All the mentioned methods I've seen here are not bullet proof references to a database tables field name. If you reset the Data Source at this stage, your values for updating will be lost. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working. Please give some references and/or details of how to. Ok what's happening is that you are binding the data source for the Grid View every time a postback occurs in the Page_Load method. Count ----------- The most common problem for losing new data entered while updating a Grid View or Data Grid is that you are resetting the Data Source for the Grid View or Data Grid in the Page_Load method. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working.Please help me with writing a Row Updating function in C#, I don't know how to grab the current field's value and also get the old value for one of keys (which is Project Name for editing) of the selected row. the idea wa to don't allow binding the grid view after a post back. hello my problem was that my gridview editable controls heep their old values. this is due to the grid view binding in the page_load method after every post back. Please review the attached examples: How to set and get a value of an unbound control within the Edit Form An example with an editable unbound column Thanks, Nick Nick, Thank you.It was the underlying data source that was not editable which caused the fields to be read-only in edit mode.

Then On Row Updating use the page variable as the new values. To initialize editors on the grid's Edit Form, you can use the Init New Row event (it's fired for new rows only) or the Html Edit Form Created event.

I've seen a number of "answers" which only provide the text in the selected row of a gridview, or the header text which both do not answer the question that was asked... If you were going to do audits of updates in a system and wanted to compare old values and new values and only update if they change and want to indicate which field was updated how do you show the database table field name at the index of the loop.

For instance: So the questions is how do you get the database table field name by index via code behind?

Get String("Grid View_Unhandled Even t", new object[] { this.
