Rowupdating e newvalues
So what you need to do is store the data source (maybe in Session) and only bind rebind the data when you absolutely need to (Like during the Is Not Post Back) Do you understand?
Please post the code for your Page_Load method and the that handles your Update (your C# code) so we can have a better look at what's going on. Please give some references and/or details of how to. This wipes out the data provided by the user during editing (editing happens after the page load).
But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.
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.
Update() End Sub one of my other fields does not work either.
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.
The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set.
Which means I won’t make my 70% code reduction Microsoft has always promised me.
To String Message="Conversion from string "Location Name" to type 'Integer' is not valid." I would prefer to get the cells by name rather then by location e.g. Keys is an array of all the data keys you define for the gridview (Data Key Names="id", where "id" is the field name from your database query) e. Old Values are arrays of all the fields in the gridview data source that are NOT leys, where, as you might guess, e.
You access the values stored in the event by index or name: e. So, to update, you might set the parameters as id = e. of course, if I have 20 columns I could define 20 data keys but I just wondered if there is another way instead of: Sql Data Source Locations.
Text could not avoid the cell numbering :/ somehow select Row.
