Providing Images

This topic describes how to provide images for the Image and Bound Image dashboard items.

Providing Static Images

To load an image into the Image dashboard item, use the Ribbon's Load Image and Import Image buttons in the Open group on the Design tab of the Image Tools contextual tab set. You can alo use the corresponding menu buttons in the toolbar (the Image_LoadImage_Toolbar or Image_ImportImage_Toolbar buttons, respectively) or commands in the context menu (Load Image... and Import Image..., respectively).


These commands invoke the Open dialog, which allow you to locate the desired image.

The Load Image command saves the path to the image in the dashboard definition, while the Import Image command saves the image itself.

To load an image in code, assign the image URL to the ImageDashboardItem.Url property, or provide the image as a byte array using the ImageDashboardItem.Data property.

Binding the Bound Image to Data

The Bound Image dashboard item provides the Attribute data section containing the corresponding placeholder.


You need to specify the binding mode for the Bound Image by clicking the Options button (the BoundImageAttributeOptionsButton icon) next to the Attribute placeholder. This invokes the following dialog.


This dialog provides two options.

  • Binary Array - Use this mode if images are stored in the data source as byte arrays.
  • URI - Use this mode to locate images accessible by a predefined URI. In this case, the data source field should return strings that are parts of URIs to these images. For instance, the URI pattern in the form below specifies the path to the folder containing the required images.


    C:\Users\Public\Documents\DevExpress Demos 18.2\Components\Data\ProductDetailsImages{0}.jpg

    Data source field values will be inserted to the position of the {0} placeholder. Thus, the Bound Image maps the current dimension value with the image placed at the specified URI.

To bind the Bound Image to data in code, do the following steps.

Note that the Bound Image can display only a single image simultaneously. If Master Filtering is not applied to the Bound Image, it selects the displayed image in the following ways.

  • In the Binary Array mode, the displayed image cannot be predicted precisely as a result of sorting limitations for the image/binary data types. Use the Master Filtering feature to display the specified image.
  • In the URI mode, the Bound Image displays an image corresponding a first attribute value taking into account the attribute's sort order.
