![]() The following code snippets (auto-collected from DevExpress Examples) contain references to the TreeListControl class. ![]() To simplify managing hierarchical data (without writing additional recursive code), the WPF DXTreeList ships with an easy to use API, so you can sequentially visit nodes starting from a specified node down to the last node. The only requirement is that these data objects should have common fields (columns). ![]() Nodes can be represented by objects of different types. You can manually create a Tree in XAML or code. The information is displayed in a TREE from hierarchical data structures. To bind the TreeListControl to a data source, use the DataControlBase.ItemsSource property. This view supports multi-column display of hierarchical data, data shaping and layout customization features such as Sorting and Filtering, Data Editing via Embedded Cell Editors, Column Auto Width, Column Reordering and Resizing, Fixed Columns, Field Chooser Window and Extendable Context Menus. ![]() It presents the most widely used method of presenting data - TreeListView. The TreeListControl uses the same View-based data presentation approach introduced by the WPF GridControl. This includes: data editing, automatic and custom sorting and filtering, full end-user customization options, editable unbound columns and DevExpress Expression editor, built-in validation, automatic and manual summary calculation, UI virtualization and per-pixel scrolling, template and style support, UI localization, extendable context menus, design-time support and much more… The TreeListControl inherits the majority of features exposed by the WPF Grid. tag property in coding but it would take alot of work maybe there is an easier way.If you want to display only single-column data, you can use the TreeViewControl. and please help how to set the tag property automatically for each data to the said diagram. it worked without the fetching of data but after fetching the data it didn't work. where in when I drag the data fro the grid control it would become a diagram on the diagram control. I have tried searching for different topics that could help me but the program doesn't really tell me where the error is but I hope someone could help me with this. = 2 ĭataTable transactionSteps = dataAccess.ExecuteQueryDataSet( " select WF_STEP_DESC1 from WF_STEPS where wf_id= 10101 and MODULE_CODE= '" + cmbProject.Text + " '").Tables GrdDocuments.DataSource = transactionDetails Private void FillTransactionDetails( int systemTransactionId)ĭataTable transactionDetails = dataAccess.ExecuteQueryDataSet( " SELECT DOC_TYPE_DESC1 FROM WF_SYSTEM_TRANS_DT WHERE SYS_TRANS_ID=1001 and MODULE_CODE= '" + cmbProject.Text + " '").Tables Var tool = new FactoryItemTool( " ", () => " ", diagram => new DiagramShape(BasicShapes.Rectangle), new ( 150, 100), false) ĭ(DiagramCommandsBase.StartDragToolCommand, tool, null) Var draggedRow = (gridHitInfo.RowHandle) as Item Return gridHitInfo.InDataRow & (Math.Abs(location.X - mouseDownLocation.X) > 2 || Math.Abs(location.Y - mouseDownLocation.Y) > 2) Private bool CanStartDragDrop(Point location) Private void grdTransactions_MouseLeave( object sender, EventArgs e) GridHitInfo = grdVTransactions.CalcHitInfo(e.Location) Private void grdTransactions_MouseDown( object sender, MouseEventArgs e) If (e.Button = MouseButtons.Left & CanStartDragDrop(e.Location)) Private void grdTransactions_MouseMove( object sender, MouseEventArgs e) Private void btnSalesInvoice_Click( object sender, EventArgs e) GrdTransactions.DataSource = dtTransactions LblCurrentProject.Text = cmbProject.Text ĭataTable dtTransactions = dataAccess.ExecuteQueryDataSet( " select sys_trans_id, sys_trans_desc1 from WF_SYSTEM_TRANS where MODULE_CODE= '" + cmbProject.Text + " '").Tables Private void cmbProject_SelectedIndexChanged( object sender, EventArgs e) Project intiation // Fill drop down for project listĭataAccess dataAccess = new DataAccess(GlobalFunctions.GetConnectionString()) ĭataTable dtResult = dataAccess.ExecuteQueryDataSet( " select MODULE_CODE ,MODULE_DESC from SYSTEM_MODULES where module_is_active=1").Tables ĬmbProject.DisplayMember = " MODULE_DESC" TODO: This line of code loads data into the 'vA_ERP4_ADMINDataSet.SYSTEM_MODULES' table.
