PONeed Help with Page Life Cycle(I think it is screwing me up)
text
Body
copied!<p>I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those. </p> <p>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.</p> <p>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.</p> <p>This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away. </p> <p>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.</p> <pre><code>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 } </code></pre> <p>So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user.</p> <p>Does not work</p> <pre><code> 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 } </code></pre> <p>Fails also.</p> <pre><code>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() } </code></pre> <p>This last one does nothing as for some reason it does not update anything. I don't understand why.</p> <p>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.</p>

Querying!

An individual column

Larger individual text columns get their own page to allow for proper reading.
