DataSet Property not re binding to datagrid

[Nick P]

I have declared a DataSet Property on by base winform control as
follows:

public DataSet MessageDs
{
get
{
return messageDs;
}
set
{
messageDs = value;
}
}

i then use this on my child control to bind to a datagrid

dgMsgTags.SetDataBinding(this.MessageDs, "MsgTags");

My problem is it only binds the first time. If I change data in the
dataset and try to rebind to an already bound datagrid it just does
nothing the data stays the same but it does not throw an exception. I
can updated the datagrid if I just use another Dataset and do not use
the property but this is not what I want to do.

I change the data in the Dataset as follows:

DataSet dsTags = this.SQLService.GetDS(strSQL);
DataTable dtTags = dsTags.Tables[0].Copy();

//Update DataSet Property
for(int intIdx=0; intIdx < this.MessageDs.Tables.Count; intIdx++)
{
// Remove Message Tags Data Table

if(this.MessageDs.Tables[intIdx].TableName.Equals("MsgTags"))
{
this.MessageDs.Tables.RemoveAt(intIdx);
this.MessageDs.Tables.Add(dtTags);
this.MessageDs.Tables[intIdx].TableName = "MsgTags";
}
}

The above code seems to work fine and puts the expected data in the
dataset for me, it just won't re-bind to the datagrid.

Anyone any ideas?

Thanks in Advance,

Nick
