Hi all,

Got a problem I can't seam to figure out.

I have a form that contains 2 textboxes and 2 datagrids.

The textboxes hold a date that can be selected by clicking a button. the button opens a popup date selector that populates the forms date box.

The datgrids also have a button attached to them that brings up a popup where the user can select a value that is then dynamically inserted into the datagrid.

The insertions are working as expected. I click the button, the popup comes up, I set the values, click ok in the popup, the data is added as a new row in the datagrid. The unwanted behaviour is this. If I add my row to the datagrid through the popup, then select any of the buttons the form does a postback and my datagrid reverts to it's viewstate thereby erasing the row I just dynamically entered.

Is there a work around to this? For instance, is there a way to dynamically add the row to the datagrids viewstate. What can I do to ensure that the rows I dynamically add to the datagrids remain after a postback of the page?

Any help is appreciated.

you can't add a row to a datagrid in this manner and its reason is exactly the same you mentioned,you must add a row to the datasource for your grid then re-bind the grid.also check out this thread.

Hey all,

I fixed this issue and thought I would post the fix for those that may need it. As my previous post stated the issue I was having was my form was posting back every time I clicked the button to enter a date. Thereby, erasing all of the changes I had made to the datagrid.

What I did was replace the asp button that opened my datepicker and entry form for the datagrid with an html button. I set the html buttons onclick even to a custom method that opened the correct form. When the user completed all of the changes to both the date text box and the datagrid they click a save button that does a post back where all of the values are saved to the database.

The routine for updating the database was a little tricky because I had to pick out the rows in the table that had actually been changed. It's important to note that when I was looking for changes to the datagrid I did not use the datagrid itself. Instead I used the actual table on the form. Each time I added a new row I added that row with a different background color so the user could easily pick up that it was a new row. When I filtered for new rows from the table for entry into the database I just looked for the rows that had the different background color. I did all of this filtering client side.

Theres two keys here; one is using an html button instead of an asp button because the html button doesn't explicitly do a post back. The other is to work with the form table client side and not the datagrid server side.

Hi,

I am looking for code to add rows dynamically to the datagrid at client side. Can you post what code/script you used to add rows to the table control. Appreciate your help!

Thanks,
