Saving Data to a DB (and other things)

Hi,

I have bound data to an InputFormview that I have made:

SqlConnection myCon = Connect("myDb");

string query = "Select * from MyTable";

DataTable aSample = new DataTable();

SqlDataAdapter aSampleAdapter = new SqlDataAdapter(query,myCon);

InputFormview.DataSource = aSample;

InputFormview.DataBind();

And then in the .aspx file

<input id="Si" value="<%# Eval("Silicon") %>" />

This works fine, it puts the values where I want them.

So, then after I have updated my values, I want to save them, this is where I stumble. If I were making a WindowsForm I would just do

aSampleAdapter.Update(aSample);

Provided that aSampleAdapter and aSample is accessible from my SaveButton_OnClick function.

But how do I do this for a Web application? If I do the same my Savebutton will do a postback before it actually runs my function, so it will clear aSampleAdapter and aSample (and everything else), then it will do PageLoad and then it will run my Savebutton_OnClick function...

Can I do this without doing a postback? Or am I totally wrong in how I approach this?

 

Thanks,

Mattias
