DataGrid doesn't display changes ???

[Chris]

Hi,

using a DataGrid :

I set the TableStylesCollection and GridColumnStyles at designtime .. map to
a DataSource and everything ..
but the Datagrid doesn't use those settings (not at design-time nor at
runtime) ???

It always uses the default layout being : showing all the columns that are
available in the DataSet it is bound to.

What am I doing wrong ?

If I set the TableStylesCollection and GridColumnStyles at runtime (setting
the DataGrid styles in code) then it works when I run the program.

Thanks

Chris

Did you use Datagrid1.Update or Datagrid1.Refresh?

It'd help if I saw the code but here's a sampe we use... it almost sounds
like the styles are being set but not added.

Hi,

thanks for your suggestion but ...
I have no coding to show... that's my whole point. I've been doing it the
way you do in your code and it works ... but I try to make it work as well
without having to code the styles, so just by setting the properties of the
DataGrid at design time.

try it out : select the properties of the DataGrid, set the DataSource to a
created DataSet-object (via the dataadapter is how I created the
DataSet-obj)
and then set the TableStylesCollection and GridColumnStyles properties

But it doesn't work. Well, the grid accepts the properties (no errors or
anything) but it displays in the form just the same as before setting any
style-properties at all ??

Any ideas ?

I executed dataGrid1.Update() or refresh() .. nothing. and actually I would
like see the changes without have to execute the app first (it works fine if
using a web-DataGrid in a WebForm, there yhou see the changes even before
running the app)

Thanks

Chris

Hi Chris,

The most forgotten thing is always is not setting the Mappingname from the
styles to the right table, however you told you did, are we talking about
the same, the Mappingname in the Styles propertie box?

You can of course show us the code, when you open the plus on the designer
created code you will see somewhere someting as
'
DataGridTableStyle1
'
You can copy that, paste it in a notebook, copy that back and show us that.

Maybe we can help you then better when my answer above does not.

Post the code that fills your dataset and the code that you are using for a
style. I know you said you are doing what Bill is doing but I want to see if
you are mapping properly.

Indeed , that's why !

I forgot to set the MappingName of the TableStyles-coll to the name of the table used in the DataSet

Thanks Cor !!!
