DataGridCommandEventHandler

[Guest]

Hello EveryBody,

How can i assign dynamically the DataGridCommandEventHandler to a
dynamically created link buttons command property.

as i have been trying to do the following
in the ItemDataBound event of the datagrid , I am dynamically creating a
link button and assigning the command property with
DataGridCommandEventHandler ,like below:

LinkButton lButton=new LinkButton();
lButton.Text ="Add Details";
lButton.ID ="flagbutton";
lButton.CommandName="changeFlag";
lButton.Command +=new
System.Web.UI.WebControls.DataGridCommandEventHandler(this.HighRevenuePaxDg_ItemCommand);
//where HighRevenuePaxDg is the datagrid.

I am trying to add the itemcommand event handler of the datagrid, so that
the click of the link button should invoke the event
"HighRevenuePaxDg_ItemCommand".

But i am getting a compile time error at the place where i am assigning the
event to the command property of the link button
lButton.Command +=new
System.Web.UI.WebControls.DataGridCommandEventHandler(this.HighRevenuePaxDg_ItemCommand);

Error:
Cannot implicitly convert type
'System.Web.UI.WebControls.DataGridCommandEventHandler' to
'System.Web.UI.WebControls.CommandEventHandler'

so could anyone of you help me out in solving the problem and also telling
me the cause of the problem.

your expert advice would be highly appreciated.

Shiju:

I believe your issue is a result of the Command event derives from
CommandEventHandler, and the ItemCommand event handler you are specifying
uses a DataGridCommandEventHandler. One way to work around this is to use
the Button_Command event to call the HighRevenuePaxDg_ItemCommand procedure.

For example:

private void Button1_Command(object sender,
System.Web.UI.WebControls.CommandEventArgs e)
{
DataGridCommandEventArgs dgcea = (DataGridCommandEventArgs)e;
DataGrid1_ItemCommand(sender, dgcea);
}

You will not have access to the additional properties of the
DataGridCommandEventArgs in this case, of course. Alternatively, you could
create an overload of the HighRevenuePaxDg_ItemCommand procedure that takes
a CommandEventArgs parameter rather than a DataGridCommandEventArgs
parameter. In either case, you will have to assign the event using the
CommandEventHandler.
