.NET MAUI DataGrid Column Resizing
Columns inside the Telerik .NET MAUI DataGrid are resizable by default. The feature is available only on Desktop - WinUI and MacCatalyst.
On WinUI and MacOS, you can change the column width by positioning the mouse over the column's vertical grid line (in the column header) and dragging it until the desired size is achieved.
Column Resizing on MacCatalyst
To resize a column programmatically, you can use the columns Width property. For more details review the Columns Width article.
In addition, you can set a MinimumWidth(double) to the column. This property is applicable when setting SizeMode column property to Fixed. When MinimumWidth is set, you can not reduce the width of the column to a value lower than the MinimumWidth.
Disabling Resizing
Two ways to disable the resizing.
1. Disable the resizing on a DataGrid level
You can disable the resizing by setting the CanUserResizeColumns property to False. The default value is True.
<telerik:RadDataGrid x:Name="grid"
CanUserResizeColumns="False"/>
When disabling the resizing on a DataGrid level, all the columns won't be resizable.
2. Disable the resizing on a column level
To disable the resizing on a specific column, set the IsResizable property. The default value is True.
<telerik:DataGridNumericalColumn PropertyName="StadiumCapacity"
HeaderText="Stadium Capacity"
IsResizable="False"/>
