Hi,
I've created an editable grid which allows the users to add new rows (using
a Postback) on the the fly and save this information back to the database.
I pretty much have my control like the one in the Docs for Creating a
DataBound Templated control.

Here is how I would like things to work:
1. The user adds new rows (this works)
2. They hit save and the information is stored to the database (works too)
3. The information is then rebinded to the control (this doesn't work). I
want to reflect the values in the database without completely reloading the
page. It seems there is viewstate data that is conflicting with what is
being rendered in the controls of the individual rows.

I don't want to have to reload the page from scratch. How can I do this?

Opps. I forgot to mention that the problems occurs after a postback that
happens after the postback which rebinds the data.
Like this
1.Save button clicked
2.Postback - Data is saved and rebinded
3.Page is rendered (looks ok)
4.Another button is click that causes a postback (can be any button)
5.Postback
6.Page is rendered but with problems

thanks,
-Ray

Does anyone have any ideas on re DataBinding? I'm desperate for some help
on this.

thanks,
p.s. Sorry, I don't have a VB version. I also didn't post the complete
code, but I think the important parts are there.

*************************************

Opps. I forgot to mention that the problems occurs after a postback that
happens after the postback which rebinds the data.
Like this
1.Save button clicked
2.Postback - Data is saved and rebinded
3.Page is rendered (looks ok)
4.Another button is click that causes a postback (can be any button)
5.Postback
6.Page is rendered but with problems

thanks,

Hi,
I've created an editable grid which allows the users to add new rows (using
a Postback) on the the fly and save this information back to the database.
I pretty much have my control like the one in the Docs for Creating a
DataBound Templated control.

Here is how I would like things to work:
1. The user adds new rows (this works)
2. They hit save and the information is stored to the database (works too)
3. The information is then rebinded to the control (this doesn't work). I
want to reflect the values in the database without completely reloading the
page. It seems there is viewstate data that is conflicting with what is
being rendered in the controls of the individual rows.

I don't want to have to reload the page from scratch. How can I do this?

Here it is:

I am doing the same thing. My Grid however uses clientside javascript to add
new rows or delete/modify existing. On Postback I update the database and
after that using the posted back values recreate the Grid. I use the
AddSubParsedObject override in TemplateItem class and
SetDataBoundString(index,value). Still not finished it though, because have
no free time to work on it.

Regards,
Deyan Petrov

I fixed the problem without fully understanding the answer. I had two
controls defined at the class level like so:
private LinkButton AddButton = new LinkButton();

so to fix the problem I put this in OnDataBinding:
this.AddButton = new LinkButton();

I guess the main control needs a new instance of the child controls to clear
everything out? Can someone explain this to me?

thanks,
