Hola, tengo un problema con 2 UniDbGrid relacionados con Maestro/Detalle. Agrupo los datos por un campo de la UniDbGrid y empieza el problema. El problema es que si me desplazo con el teclado (por ejemplo, presiono y mantengo presionado hacia arriba/abajo, la cuadrícula de detalles no puede mantenerse al día con las actualizaciones y las paradas. Solo funcionan los clics del mouse. Estoy usando el evento afterscroll para actualizar la cuadrícula de detalles, pero si me desplazo hacia arriba y hacia abajo varias veces, el afterscroll simplemente deja de funcionar. procedure TUM.qConPedidoAfterScroll(DataSet: TDataSet); var id:integer; begin id := Dataset.fieldbyname('id').asinteger; qdetalle.Close; qdetalle.ParamByName('IDPEDIDOS').AsInteger:=Id; qdetalle.Open; end; ¿Puede darme una solución con alguna funcionalidad en DBGrid, o quizás pueda recomendar una solución alternativa? Actualizar master-detail no es un problema en el escritorio, pero en la web es completamente diferente. Gracias.

Hi, How to reverse the column number with multiselect in unidbgrid. Regards.

Can anyone explain why (or what would cause) UniDBGrid.RecordCount event to be called several times upon the creation and initial display of a form? In fact, it's called approximately 6 times before the form finishing loading. Even weirder, it appears to be called even before the table has even been opened, based on my logging snippet below: [2 µs][Trace][Value: TframeItem.UniFrameCreate][Type: string] [1040 µs][Trace][Value: TframeItem.UniFrameBeforeReady][Type: string] [25689 µs][Trace][Value: TframeItem.UniFrameReady | begin][Type: string] [29 µs][Trace][Value: TframeItem.tblItem_BeforeOpen][Type: string] [5420560 µs][Trace][Value: TframeItem.UniDBGrid1RecordCount][Type: string] [1876286 µs][Trace][Value: TframeItem.UniDBGrid1RecordCount][Type: string] [18 µs][Trace][Value: TframeItem.UniDBGrid1RecordCount][Type: string] [1196 µs][Trace][Value: TframeItem.tblItem_AfterOpen][Type: string] [2 µs][Trace][Value: TframeItem.tblItem_AfterScroll | begin][Type: string] Thanks in advance.

Hi After ticking each of the selected cells in Test Case, the horizontal scroll will jump. Rtl = True. Regards. GridCheckSelectOnly.zip

Hi, Currently any colour changes in the grid are not reflected on the export. I need to be able to persist either cell colour or text colour when exporting from a grid to make cells visually clear. Like the image below: I can get the cells to change to the respective colour on the grid within the application, what I'm looking for is a way to persist these cell colours when exporting. I am currently using the UniGridExcelExporter component calling grid.Exporter.ExportGrid; to export. Any help would be great. Regards, Wicket

@Sherzod доброе время суток. Заметил странное поведение грида, после того как уничтожаешь объект Edit, который является редактором фильтра в столбце, столбец исчезает. Срабатывает событие "onColumnHide" testGrid.zip Суть в том, что я запоминаю действия над столбцами и записываю в конфиг. При последующем построении грида, настройки столбцов считываются с этого конфига. Получается так, что при каждом перестроении грида, у меня не произвольно пропадают столбцы

I know drag&drop using two UniDBGrids are discussed and there are even demo about it but how about dragging and dropping inside one grid? I have data in which rows are ordered by indexed row number and I'd like to add feature where user can drag rows to different positions and when user does that, row numbers are updated in the background accordingly. What is the easiest and more importantly, correct way to achieve this?

Hey guys. Is there any way to add a jpg/png image to the Title of a UniDBGrid column? For this specific case, FontAwesome does not work, it needs to be an image that can be loaded or drawn. I've already researched a lot but I didn't find it (maybe I went the wrong way in the searches). Thanks in advance for any help.

Good afternoon! How can I make it so that when you set the UniDBGrid.Enabled property:=False, then the component would not turn gray, but would remain as with the UniDBGrid.Enabled property:=True, but was not available for any actions on the part of users? Otherwise, the information in it is less visible:

Hi, As the title says, I converted a library that Mike Heydon made to export a DataSet to old format Excel file (xls) without OLE or Excel installed. This library now converts an UniDBGrid to Excel. Sample of usage. // Add uses UExportExcel procedure TMainForm.UniButton1Click(Sender: TObject); var url, filename, reportname : String; exportExcel: TDataSetToExcel; i: integer; begin reportname := 'ExcelReport'; url := UniServerModule.LocalCacheURL+name+'.xls'; filename := UniServerModule.NewCacheFileUrl(false, 'xls', reportname, '', url); exportExcel := TDataSetToExcel.Create(filename); exportExcel.Grid := UniDBGrid1; exportExcel.WriteFile; FreeAndNil(exportExcel); UniSession.SendFile(filename, reportname+'.xls'); end; Hope it helps everyone.

Как перевести на другой язык пункты Lock и UnLock? Спасибо.

I have a UniDBGrid attached to a datasource. I also have a UiDBNavigator attached to the same datasource. As expected, I can navigate the datasource either by pressing the Next / Previous button in the navigator or by using the grid itself (eg. up / down arrow key or clicking on desired row using the mouse - all good, so far. Note: Moving to a different record in the datasource can potentially take a couple seconds. This happens because the Dataset.OnScroll event of the datasource applies a filter to a couple of other datasets (i.e. achieving a master detail relationship) and these other datasets themselves are bound to some visual components, many of which are displaying images from the dataset. That's mostly for a background of what's causing the delay and I will refer to this lengthy period as "THE DELAY" After enabling the ScreenMask property for the navigator... when I press a navigator button (Next or Previous) it works as I hoped it would. That is, a) press next b) Mask is displayed c) THE DELAY occurs d) finally the mask is hidden immediately after THE DELAY is complete. However, if I navigate the datasource using the UniDBGrid itself (with LoadMask enabled)... a) no mask is ever displayed b) I can navigate the records immediately back-to-back without THE DELAY c) however, if I quickly move to 3 different records THE DELAY gets "queued" up and does in fact happen 3 times asynchronously. How can I make navigation using the grid work the same as via the navigator? That is, display a ScreenMask, thereby not allowing me to make another move, until THE DELAY is completed. PS I have tried setting UniDBGrid.LoadMask with & without WaitData. And the LoadMask appears to work correctly (it appears when I change pages via the grid). Your thoughts, please.

Hi, I'm trying to put the Filtering.Editor option on dynamically created columns in a UniDBGrid, but it doesn't work at all, in all the ways I try, I get the message "Argument out of range" when running.
