DataRecordCellAreaGridTemplate and Resizing

275

I've set the initial column widths of my grid using FieldLayoutSettings.DataRecordCellAreaGridTemplate which works fine. However i want to give the user the flexibility to adjust the width, in which i set the AllowResize to true in the FieldSettings.

When i start the application all seems well, but when i try to resize my application crashes.

Resizing a field shouldn't cause a crash but the recommended method of controlling the size of the fields is to set the Width (or FieldSettings.Width) in v9.2 and later or the FieldSettings->CellWidth/LabelWidth properties (either via each Field's Settings and/or the FieldSettings of the FieldLayout/DataPresenter). The DataRecordCellAreaGridTemplate was primarily meant as a means of controlling which fields were * columns when using autofit but with the addition of the FieldLength typed Width/Height properties in 9.2, this really isn't needed any more.. The DataRecordCellAreaGridTemplate is limited in that when fields are moved the size of the columns affects whatever field then occupies that column in the grid as opposed to controlling the size on a specific field. Note I tested resizing a field in a grid using a datarecordcellareagridtemplate and was not able to reproduce the crash so that may have been addressed in a hotfix.

I'm now using the v 2009.2 and the client doesn't crash anymore.

Regarding DataRecordCellAreaGridTemplate if this is not any more approriate how could i set the initial width at start in which i expect to get 5 fields. The first get 25%, second 30% ... and last gets the rest. Also the AllowResize is set to true.

Aside from the main topic i've noticed that when the AllowFieldMoving is set to No in v 2009.1 the fields weren't draggable but in the latest version this is possible, just that the moving doesn't really takes place.

So I'm guessing you want autofit then since the %'s only make sense when autofit is enabled. If that's the case you can set the Width property of the Field to * values - e.g. 25*, 30*, 45*. Note, this is a little different than star values since the preferred sizes are assigned first and then the remaining is assigned based on the weights but the effect should be similar.

Yes this is correct. One of the new features in 9.2 was the ability to drag field headers into the group by area to group by those fields so its allow you to drag since the AllowGroupBy for the fields is true by default. You can change the FieldSettings->AllowGroupBy to false to disable grouping for that field or you can set the GroupByAreaMode to DefaultFieldLayoutOnly which is essentially the behavior available before - that only the root field layout supports grouping and the way that you group by a field is to go to the group by area box and drag a field from the list in that box into the group by area above it.
