ColSpanTagHelper class | QSYS API Reference Guide

Provides a ColSpan tag helper to Razor elements.

Namespace: ASNA.QSys.Expo.Tags Assembly: ASNA.QSys.Expo.Tags.dll

Inheritance: Object –> TagHelper

Remarks

Legacy DDS for display files described field and constant Display positions using a grid-like row and column coordinate system. Typically a field was described with a start-position spanning to an end-position according to its width (or field length).

Sometimes it is desirable the override the end-position by providing a Column Span value that extends the bounding-box of the field or constant beyond the natural calculation of the end-position (as in start_position + length).

For example, the constant “Selection” in the markup below, has a character length of 9. Without the ColSpan property, the end-position would be calculated as: 4+4+9 = 17. Instead we want the constant’s bounding box to extend to position 23 (that is 4+4+15).

Extending a DdsField’s or DdsConstant’s width may be desirable when a CSS style wants to be applied (such as background-color).

    <div Row="3">
        <DdsConstant Col="4+4" ColSpan="15" Text="Selection" Color="DarkBlue" />
        .
        .
        .
    </div>
