Web Forms :: Retrieve Dynamic HtmlTable Data?
Feb 22, 2010
a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button).
These rows contain textboxes, dropdownlists, checkboxes and other input controls.
When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on the server side, validate it (yes all rows at once) and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows.

I have created a dynamic table using user entered values for Rows and columns. After the table is created the data is populated on the table. I have a separate event that is clicked to retrieve this data, but I am not able to get this data upon postback.
I need to convert the table values (in int) to an array for further processing.

I have a form in a page and a panel inside the form.The panel gets loaded with dynamic controls like radio button and text boxes.
User is allowed to choose any radio option and enter any value in the textbox beside it and then goes for submit button to move to next stage.
Problem Descritopn:
I load the controls in the panel based on the index of a combo control on the same form.it is done in selectedIndexChanged - This is working fine.
When i go for the submit button and ask for the textbox control, it says "object reference not set to instance of object", denoting that instance is not available. Moreover the panel control list gets empty automatically.

I'm working with a website written in aspx.net over vb.
I have a placeHolder, and I create a table of names inside this PlaceHolder, each name has an HtmlInputCheckBox next to it.
Im doing this in the aspx.vb file, when the page is uploading.
Then, when the user wants to send mail, he presses a button and than I need to access the checkboxes, and I'm having problems with this, the Sub doesn't know the checkBox object.

I have a website, where I load some info into 6 table rows.
Every row loads a different thing and it lasts a different amount of time.
Loading of the whole table takes a lot of time (5-15 secs), so What I would like to do is to load every row with an AJAX UpdatePanel (or 6 UpdatePanels) like this:
When the loading of one row's data is finished, the table row is displayed with the data.
Then row by row finish loading and are displayed too.

If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.

I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
