Microsoft.Maui.Controls.BindableObject: Warning: Value is an invalid value for Maximum

[PuppyLo]

I'm new to MAUI.

This error keeps popping up:

Microsoft.Maui.Controls.BindableObject: Warning: Value is an invalid value for Maximum’ 

Trace.WriteLine($‘PaginationStepper Maximum: {DataGrid.PageCountProperty.DefaultValue}’ gives ‘PaginationStepper Maximum: 1’.

Can you tell me what to do?

<datagrid:DataGrid ItemsSource="{Binding TradeDataGrid}" PaginationEnabled="False" PageNumber="1" PageSize="5" >
            <datagrid:DataGrid.Columns>
                <datagrid:DataGridColumn Title="USDT" PropertyName="[0]" />
                <datagrid:DataGridColumn Title="BTC" PropertyName="[1]" />
                <datagrid:DataGridColumn Title="USDD" PropertyName="[2]" />
                <datagrid:DataGridColumn Title="HTX" PropertyName="[3]" />
                <datagrid:DataGridColumn Title="TRX" PropertyName="[4]" />
                <datagrid:DataGridColumn Title="ETH" PropertyName="[5]" />
                <datagrid:DataGridColumn Title="XRP" PropertyName="[6]" />
                <datagrid:DataGridColumn Title="LTC" PropertyName="[7]" />
            </datagrid:DataGrid.Columns>
        </datagrid:DataGrid>

Here's a piece of code just in case

 private void UpdateGrid(List<List<string>> allData)
 {
     try
     {

         for (int i = 0; i < 10; i++)
         {
             var row = new List<string>();
             foreach (var currencyData in allData)
             {
                 row.Add(i < currencyData.Count ? currencyData[i] : "");
             }

             Trace.WriteLine($"PaginationStepper Maximum: {DataGrid.PageCountProperty.DefaultValue}");

             TradeDataGrid.Clear();


             TradeDataGrid.Add(row);
         }
     }
     catch(Exception ex)
     {
         Trace.WriteLine(ex);
     }
 }

Seems like there could be bugs in both this control and your usage.

I see you set PaginationEnabled="False" and it still throws this error even when disabled?

Setting an invalid page number should probably fallback to a reasonable value, instead of failing. An erroneously low value should default to 1, and an erroneously high value should default to the last page. And a hardcoded value of 1 should never fail, even when there are no records.

I will review the code to ensure this is the case. Until then, I recommend just removing the PageNumber="1" attribute unless there's a strong reason to need it.

I added these attributes just to see if the error would go away but no, tried different options but nothing worked.
Initially it was just <datagrid:DataGrid ItemsSource=‘{Binding TradeDataGrid}’ >

It is possible the error is not coming from the DataGrid at all.

Also, the use of the square brackets to define the property names for the columns is unlikely to work. Although the error you showed seems unrelated.

Make a normal collection and define the properties that way. You can also use sub-properties with a dot as the defined PropertyName.
