问题 I made my grid group by date (grabbed the column name and dragged it to where it says 'group by that column'). However, when the grid is displayed all the dates are 'closed' so I must expand them to see data. That is OK but I wonder if it is possible to have current date expanded already (all other should remain closed !) so I do not have to click the expand cross? 回答1: try this, you can put the code in other event handler like a TButton for example procedure TForm1.FormCreate(Sender: TObject

问题 I am printing a details subreport that gets printed let's say 5 times on the overall report, for 5 query results. I compute some stuff for it with my code, and so I use BeforePrint event on an XRTable widget that I have in that subreport. So far so good. What I don't like is that when the BeforePrint executes for that table for the first time and I change its cells' text to something, that this renders on all subsequent instances of this report and table being printed. Now, obviously, since

问题 I am currently using DevExpress 10.2 within Visual Studio 2010. I am printing the contents of the GridControl (with both one and two GridViews contained within). This shows all the current visible columns (and not the invisible columns) and all the data in a viewable manner.

I want to make it so that if the user has none of the groups or rows expanded then the print preview displays the

问题 On my dxBarManager1Bar1 a cxBarEditItem1 is a checkbox. How can I check it's state (if it's checked or not checked) ? 回答1: For accomplishing your task, you can use the EditValue property. if (cxBarEditItem1.EditValue <> Null) AND (cxBarEditItem1.EditValue = True) then ShowMessage('Checked!') else ShowMessage('Not Checked! (or null)'); Note that EditValue is a Variant property which can also have Null value. 来源： https://stackoverflow.com/questions/41296661/if-a-cxbaredititem1-is-a-checkbox-how

问题 I am currently using DevExpress 10.2 within Visual Studio 2010. In a previous question I was trying to print the current user view of a DevExpress GridControl with the user's choice of expanded or collapsed master rows and/or group sections.
