Hello,

I've a RadGrid bases on a datatable. On initial binding the pager item does not show up. When refreshing the grid it does.

Can anyone help me?

Hello jos,

There is not any such type of issue with radgrid.
Then also please try with below code.

<PagerStyle AlwaysVisible="true" />

Thanks,

Hello,

Try setting AllowPaging as true and VirtualItemCount property . Also take a look into the following documentation.

Custom Paging

Thank you all for the input.

The problem was caused by setting the PagerStyle.AlwaysVisible option on the OnPreRender. That was to late obviously.
Moving this to the Page_load solved the problem.
