Change Headertext programmatically

[Viktor Takacs]

HI,
I am trying to set the HeaderText property of the columns in a RadTreeList, however, it doesn't seem to respond to the following command:

tlCategories.Columns[0].HeaderText = common.RM.GetString("ctName");

The column's header stays empty.
If I use the HeaderText attribute in the aspx file it displays it correctly.

I am back to a previous issue I encountered with a GridView. Are these related? Any way around it?

By the way: the localization example on your deom site doesn't work at all: it fails to display localized resources and when I click on the related files link it gives me a no access error...

Any pointers would be greatly appreciated!

HI,

I think I spoke a bit too fast... sorry about that....
It does display something in the header, but according to the Culture. So the same issue happens as with the DataGrid.
thanks

Hi Viktor,

The best way to access a column in RadTreeList is to use its UniqueName:

tlCategories.Columns["Column_UniqueName_here"].HeaderText = common.RM.GetString("ctName");

For more information, you can check the below articles:

Regarding the mentioned demo: can you check it now and let me know if you find any issues? The broken link should be already fixed.

Kind regards,
