Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(2)]
[Parameter]
int Rows { get; set; }

Property Value

Type	Default	Description
Int32	2	The number of text lines.

Remarks

Use the Rows property to specify the number of rows at runtime. If the text does not fit the specified number of lines, the component displays a scrollbar. To change the number of rows in markup, use the DxMemoSettings.Rows property.

The IMemoSettings interface allows you to get and customize settings of a memo 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 memoSettings = e.Grid.GetColumnEditSettings<IMemoSettings>("Notes");
  if(memoSettings != null) {
      e.Grid.BeginUpdate();
      memoSettings.Rows = 3;
      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 IMemoSettings memoSettings)
          memoSettings.Rows = 3;
  }
  

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

  void Grid_CustomizeDataRowEditor(GridCustomizeDataRowEditorEventArgs e) {
      if(e.EditSettings is IMemoSettings memoSettings)
          memoSettings.Rows = 3;
  }
