Changing datagrids Headertexts /events in an dynamically created datagrid

[Anna Schmidt]

Hello,

I'm currently working on a dynamic generation of a Datagrid (without aspx )
files.

the basic Idea is sending a DataTable to my viewDatagrid class, so the
columns are determined and dates/numbers are formatted, styles are set etc.,
that works fine. so need to define fields in the aspx.files

Everything works fine, except I can't change HeaderTexts of
Datagrid.Columns. Besides, I can't bound events to this dynamic dg2.

viewDataGrid vd = new viewDataGrid(myDatatable);

DataGrid dg2 = new DataGrid();

dg2 = vd .GetDataGrid(); // after formatting a new Datagrid is returend
//databind is already happened.


dg2.Columns[1].HeaderText ="Name"; // doesn't work at all, instead
fieldnames from datatable used instead

dg2.ShowHeader = true; ///-->works fine

dg2.ShowFooter = false; ///-->works fine


this.Controls.Add(dg2); // adding in the pageload methods

I think It's because databinding already happened in the GetDataGrid()
method. but how to change headertexts afterwords? i want to set my
headertexts in the aspx.cs file, not in my Helper-Class ???

Has anyone got an idea, why this doesn't work? and why can i change the
general preferences, but not the data?

Or is there a better solution for dynamically creating a datagrid from a
datatable?

any help is appreciated.

Thankyou as.

when you bind to the datagrid you will need to place code inside the
itemdatabound event handler to adjust the title of the columns.
if(e.item.itemtype == listitem.header)
e.item.cells[0].text = "new header";
