#C CHANGE GRID COLUMN TYPE CODE#

To remove a column in code, call the or method.Ĭolumns that you create in code are invisible even after you add them to the Columns collection. To remove a column, utilize the “Remove Column” designer button, or click a column header at design time and press the “Delete” key. Otherwise, a column is unbound and does not receive cell values from a data source. In this case, you need to set every column’s GridColumn.FieldName property manually. You can also utilize the “Add Column” and “Insert Column” buttons on the same designer page. Data fields that have no corresponding grid columns are highlighted with bold text. To add such columns manually, invoke the Data Grid designer, switch to the “Columns” tab and click the “Show Field List” button, then drag a data field into the column list. See also: Obtaining Fields Available in Data Source.Ĭolumns associated with data fields declared in a data source are called bound columns. See this help topic to learn more: Unbound Columns. In addition to regular columns that retrieve data from a source, Grid Control also supports unbound columns that display custom values. The “Display” attribute in the code below prevents the Data Grid from generating an “Additional Info” column. For code-first data sources (for example, Entity Framework models), you can mark a property with the Display attribute and disable its AutoGenerateField parameter to skip column generation for this property.

When you bind a Data Grid to a data source, the control automatically generates a column for each bound data field (if the AutoPopulateColumns property is not disabled). This limitation also applies to other data-aware controls (Data Grid, Tree List, Vertical Grid, etc.).įor information about the similar functionality in other data-aware controls, refer to these help articles: Columns (Tree List), Rows (Vertical Grid), Pivot Grid Fields (Pivot Grid). If you need to do that, create Unbound Columns and handle the CustomUnboundColumnData event to manually copy data source values to unbound column cells. You cannot bind multiple Data Grid columns to the same data source field.
