For example, if a column has one cell with a long word like "hippopotamus" contained within it but all the other cells in the column have smaller words like "dog", the width of the column will be the width of the largest word (hippopotamus). Grid is the only layout panel that can distribute space in this manner.īy default, rows and columns take up the least amount of space necessary to accommodate the largest content within any cell contained in a given row or column. By combining this technique to proportionally distribute space with a HorizontalAlignment and VerticalAlignment value of Stretch, it is possible to partition layout space by percentage of screen space. In the first case, the row or column would receive one times the available space, while in the second case, the row or column would receive two times the available space, and so on. This value is expressed as * or 2* when you use Extensible Application Markup Language (XAML). This is in contrast to Auto, which distributes space evenly based on the size of the content that is within a column or row. When Star is selected as the height or width of a row or column, that column or row receives a weighted proportion of the remaining available space. ' Add the final TextBlock Cell to the GridĪ Grid contains a collection of UIElement objects, which are in the Children property.Ĭolumns and rows that are defined within a Grid can take advantage of Star sizing to distribute remaining space proportionally. Add the Grid as the Content of the Parent Window Object Add the TextBlock elements to the Grid Children collection
Txt8.Text = "Total Units: " + (db1 + db2 + db3).ToString() RowDefinition rowDef4 = new RowDefinition() RowDefinition rowDef3 = new RowDefinition() RowDefinition rowDef2 = new RowDefinition() RowDefinition rowDef1 = new RowDefinition() MyGrid.VerticalAlignment = VerticalAlignment.Top ĬolumnDefinition colDef1 = new ColumnDefinition() ĬolumnDefinition colDef2 = new ColumnDefinition() ĬolumnDefinition colDef3 = new ColumnDefinition() MyGrid.HorizontalAlignment = HorizontalAlignment.Left In this case, the grid defines three ColumnDefinition elements and four RowDefinition elements that host child content. The grid comes with two such Cell Renderers for showing data changes which are detailed in the Change Cell Renderers section.The following example demonstrates how to create a grid. Cell Renderers have a refresh method that gets called when data changes, allowing custom animations to highlight data changes. It is also possible to have more intelligent animations by putting animations into custom Cell Renderers. Flashing Cells vs Custom Cell Renderersįlashing cells is a simple and quick way to visually show to the user that the data has changed. If you do not like this exception and would like to flash changes even when it's the result of a filter change, then set grid property allowShowChangeAfterFilter=true. It typically doesn't make sense to flash these changes when it's due to a filter change, as filtering would impact many (possibly all) cells at once, thus not usefully bringing the users attention to any particular cell. If you are Row Grouping the data with Aggregations, then the aggregated values will change as filtering adds and removes rows contained within the groups. One exception to the above is changes due to filtering. The example demonstrates how to change the default colour of the flash using the -ag-value-change-value-highlight-background-color CSS variable.Clicking Flash Two Rows will pass a custom flashDuration of 3000ms and a custom fadeDuration delay of 2000ms to demonstrate default values can be overridden.Clicking Update Some Data will update some data to demonstrate the changes mentioned above.The cellFadeDuration value has been changed to 500ms, so the fading animation will happen faster than what it normally would (1 second).The cellFlashDuration value has been changed to 2000ms, so cells will remain in their "flashed" state for 2 seconds.The example below demonstrates flashing delay changes. When calling flashCells(), pass the flashDuration and fadeDuration values (in milliseconds) as params.Change the cellFlashDuration and cellFadeDuration configs in the gridOptions.There are two ways to change how long a cell remains "flashed". If you want to override the flash background color, this has to be done by overriding the relevant CSS class. The grid provided themes use this to apply a background color. Each time the call value is changed, the grid adds the CSS class ag-cell-data-changed for 500ms by default, and then then CSS class ag-cell-data-changed-animation for 1,000ms by default.
