Need Help with Page Life Cycle(I think it is screwing me up)
- by chobo2
Hi
I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those.
Now my table gets filled up and has dropdown lists. When the user hits save I go through all the rows and update the values from the dropdownlist in the db.
This works all great. However if 2 columns have each have "Present" then those 2 columns should be not be shown anymore and 2 new columns get put in its place with other dropdown lists.
This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away.
So what I tried to do is at the end of the button click event. Clear the whole table and then regenerate it. However when I do this then my values are not saved to the database anymore for whatever reason.
if (IsPostBack == false)
{
// check if dummy variables exist in db- If true just generate tables with values in db. If not generate them.
}
else
{
// grab the values from the database
// generate tables with the values
}
btn click event
{
go through all rows in table(foreach loop)
update each column in the database with cells in each row. while in foreach loop.
//done
}
So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user.
Does not work
if (IsPostBack == false)
{
// same code as above
}
// if postback is true do nothing. By the time it gets to the click event it says there is zero rows in the table so nothing happens.
btn click event
{
// same code
}
Fails also.
if (IsPostBack == false)
{
// same code as above
}
else
{
// same code as above but moved into its own method.
gernerateTable();
}
btn click event
{
// update all rows
// once done clear the Tables rows
// call generateTable()
}
This last one does nothing as for some reason it does not update anything. I don't understand why.
So what am I doing wrong with this life cycle something in my process is wrong. The code works just not when I want the table to be updated right away.
