Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(null)]
[Parameter]
string IndeterminateDisplayText { get; set; }

Property Value

Type	Default	Description
String	null	A text string.

Remarks

Use the IndeterminateDisplayText property to change the display text string that corresponds to the indeterminate state at runtime. To specify the display text in markup, use the DxCheckBoxSettings.IndeterminateDisplayText property.

The Grid displays this string in the following UI elements:

• Filter row
• Column filter menu
• Column cells, if the ShowCheckBoxInDisplayMode property is set to false and the Grid is in display mode

The ICheckBoxSettings interface allows you to get and customize settings of a checkbox editor at runtime. You can get editor settings in the following ways:

• Call the GetColumnEditSettings method to get editor settings of the column bound to the specified data source field.

  Important

  You need to enclose your code between BeginUpdate and EndUpdate method calls to change values of Grid component parameters outside the Grid component markup. Otherwise, an exception occurs.

  var checkboxSettings = e.Grid.GetColumnEditSettings<ICheckBoxSettings>("Discontinued");
  if(checkboxSettings != null) {
      e.Grid.BeginUpdate();
      checkboxSettings.IndeterminateDisplayText = "Unknown";
      e.Grid.EndUpdate();
  }
  

• Handle the CustomizeFilterRowEditor event to customize a cell editor in the filter row.

  void Grid_CustomizeFilterRowEditor(GridCustomizeFilterRowEditorEventArgs e) {
      if(e.EditSettings is ICheckBoxSettings checkboxSettings)
          checkboxSettings.IndeterminateDisplayText = "Unknown";
  }
  

• Handle the CustomizeDataRowEditor event to customize a cell editor in a data row.

  void Grid_CustomizeDataRowEditor(GridCustomizeDataRowEditorEventArgs e) {
      if(e.EditSettings is ICheckBoxSettings checkboxSettings)
          checkboxSettings.IndeterminateDisplayText = "Unknown";
  }
