How to perform ondatabinding event?

Question

Suppose there is checkBox with id chkSelect and to perform ondatabinding event.How to do that?

Answer 1

You can add AutoPostBack="true" and OnCheckedChanged="chkSelect_CheckChanged" to your chkSelect CheckBox, then add this in your codebehind:

protected void chkSelect_CheckChanged(object sender, EventArgs e)
{
    // your code here
}

if you want to perform actions when the CheckBox is checked/unchecked.

Or add OnDataBinding="chkSelect_DataBinding" to your CheckBox and the following in your codebehind:

protected void chkSelect_DataBinding(object sender, EventArgs e)
{
    // your code here
}

if you want to use the OnDataBinding event.

Answer 2

I suppose you want to get ondatabinding event method called.

For this your check box should have event declared as:

<asp:CheckBox runat="server" ID="chkSelect" Text="CheckBox to bind" ondatabinding="chkSelect_DataBinding"/>

or

you can also do it Page_init or OnInit method as

protected override void OnInit(EventArgs e)
{

   chkSelect.DataBinding += new EventHandler(chkSelect_DataBinding);

   base.OnInit(e);
}

Now to let this event fire, you can call

chkSelect.DataBind(); in page_load. This will fire ondatabinding event.
