Describe the bug
When we set the CurrentPage of RadzenDataList component, skip value is not recomputed.

I have a data filter component which configure the request for a data list component.
Imagine that I have a configuration of 5 results per page, and my user go to page 5. Data list will set its internal skip value to 20 (skip 4 pages of 5). Now the user wants to make a new search, this search will return only 4 items. the data list will send to the server a request with skip = 20 + take = 5, so it will return no result.

We can't access property skip as it is protected

To Reproduce
Set a filter upon a RadzenDataList, change the page of the RadzenDataList and then change the filter. Results in RadzenDataList is bad

Expected behavior
We need a way to reset pagination of RadzenDataList.
A good way can be to have a binding on CurrentPage and not just a public property, and when CurrentPage changed, compute the new value for skip

There is no filter UI for RadzenDataList, where do we set the filter?

In my case for example, I have 2 searches : a simple search with a textbox and an advanced search with a full RadzenDataFilter component up to our RadzenDataList.

Only look at the simple mode as it is easier :

<RadzenTextBox Change="@(_ => _dataList.Reload())" @bind-Value="@searchValue" ></RadzenTextBox>

<RadzenDataList @ref="_dataList" LoadData=@LoadData>
...
<RadzenDataList>

client code side

private string searchValue;
private async Task LoadData(LoadDataArgs args)
{
    //Make your request on server using searchValue

}

Again , there is no UI for filtering in RadzenDataList. You have full control when and how is requested - for example you can call FirstPage() on search change. Use our forum in the future for such questions.

@enchev It's not a problem to make the search, it's a problem to change the page and reset the skip value.

You can see a similar trouble on the RadzenDataGrid component, but it seems that the grid "understand" that result count 1 and no result in the scope is not a normal state, so the grid try to decrease its skip value by the page size.

On your demo, go on DataFilter > OData, remove the existing filter and open your network console :

Copy the first Order ID (10248), then go on last page :

Now, add a filter with your first order id :

the grid make a lot of request to decrease the skip value :

Not the same behavior, but same problem. We can't reset the skip value before to start LoadData events of RadzenDataGrid & RadzenDataFilter
