How to unbind a data control... ?

Trying to UNBind a DataBound Control like GridView. I have tried many things but most popular way is to hide it using panel.

I want to know if there is any way to unbind it to null.

C#

GridView1.DataSource = null;
GridView1.DataBind();

I don't see this working ...!!! Any Ideas...????????

Please clarify what you are trying to accomplish. What do you mean "unbind"?

I m trying to do is - Reset the page to default (starting) scenario like clicking a 'Reset' does in a form. Plus I want to unbind anything that contains anything...

Can you not simply add the data source that does not contain any data ? Such as an empty ObjectDataSource, Datatable etc ?

Please have a look followings,

correct-way-to-unbind-a-bindingsource-from-a-datagridview[^]

system.web.ui.webcontrols.basedataboundcontrol.datasource.aspx[^]

and DataSource is a property of GridView class and set part of the DataSource is work something like below,

C#

...
set
{
  if (value != null)
  {
    //does some sort of validation on value;
  }
  this._dataSource = value;
  ...
}

So null value is acceptable to set DataSource property values.

Hope it helps :)
