I am using DevExpress 11.2 within Visual Studio 2010 and I am currently using the DevExpress.XtraTab.XtraTabControl within my form. I love the way the tabs look; however, I would like the tabs to be located at the bottom of the TabControl rather than the top.
View 1 RepliesI was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?
View 1 RepliesMy code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
how to focus a particular Row in devexpress

View 1 RepliesI have a DevExpress LookUpEdit that I am using withing Visual Studio 2008 in VB.Net. I have the LookUpEdit bound to my datasource and the value that it is displaying may be null or one of the rows in the datasource. My program displays a treelist and when a node is select the LookUpEdit is supposed to display the assigned value (could be null) and let the user reassign the value. I do have the LookUpEdit.Properties.AllowNullInput set to True. Right now when the program first starts if the first node in the treelist I choose has a null value the LookUpEdit displays nothing, if I change the value of the LookUpEdit the value changes in the database, if I change to a node that has a value for the LookUpEdit the value does display.
The problem is that if I switch from a node with a value to one without the LookUpEdit displays the previous value. I have gone through the debugger and it is still going through the fetch properly.
I have tried to reset the LookUpEdit.Text, LookUpEdit.EditValue and LookUpEdit.SelectedText but nothing works. I even replicated the conditions that the LookUpEdit has when it first displays nothing (LookUpEdit.Text = "" and LookUpEdit.EditValue = " ") but it still displays the last value.
[Code]...
The values are set. The problem is that in the act of setting the value the dropdown menu opens. So I get it to close with lueLocation.ClosePopup(). For some reason when it gets called it changes the .Text and .EditValue back to the previous values and thus calls the TextChanged Event.
I want to know how to get the value member value in lookupEdit.I set the DisplayMember as prior to SupplierNameAnd ValueMember to SupplierIDThe code below displays both and SupplierName as the text in lookupedit..what I want is to keep the SupplierName as the Display but I want to get the supplierID when saving it to databaseScenario: want the value of the Supplier ID for example 001 - Supplier1 Thedisplay text in the look up is Supplier1 what I want is the 001

I am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2. I just started programming with the WinForms XtraGrid FindPanel and so far it works wonders. However I was wondering if there is any way to know when the user closes the FindPanel. Right now if gridview.OptionsFind.AllowFindPanel is True and gridview.OptionsFind.AlwaysVisible is False then the user is able to click on the x and close the FindPanel. Is there anyway to catch this closing? I don't want to stop it just do a couple of things once it is hidden or closed.

View 1 RepliesI am using DevExpress.XtraEditors.LookUpEdit to display the information about the classes available. Currently it has 3 columns. The lookupedit is working perfectly except when I set the editValue to the last row. When the editvalue is set to any row other than the last one it shows the selected row when the lookupedit isn't opened yet when the lookupedit is set to the last row nothing is displayed.
[Code]...
Right now the lookupedit displays the selected text unless I select the last row, row number tableData.Rows.Count which then displays nothing. Yet when I print the values they are correct and when I remove the +1 when setting the lookupedit it sets it to the previous line I want an the first row can't be displayed.

I have a Devexpress LookUpEdit that I want to fill with 2-3 values. For example "Value 1" (1) and "Value 2" (2). I want this name to be displayMember of the LookUpEdit and the number in brackets be the valueMember so that if I was given the number 1 I know to set the selected value of the LookUpEdit to "Value 1".

I am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2, specifically WinForms. In the DevExpress GridControl at runtime you can click on the right side of the column header and choose which values in the column you want to show. For example if your table contained:
Name1 Checked
Name2 Unchecked
Name3 Unchecked
Name4 Checked
Then if you click on the right side of the checkbox's header you can choose checked (or unchecked) and it would display only the data that is checked (or unchecked). In this case with checked you would have:
Name1 Checked
Name4 Checked
I was wondering if there was some way to override the names so instead of letting me choose checked or unchecked I could override it with 'owned' and 'rented' or 'active' and 'inactive' based on what the checkbox represents in that specific column.
I am using VB.net within Visual Studio 2008. I currently have GridControl where one of the columns fetches a real number from the database. Whenever I try to remove the value I get a red 'X' saying that the input string is not the right format even though I know it can display null because the row underneath fetched a null value for that column.

I am using VB2008 on Win XP SP3 and an relatively new using this language. I would like orientation or advice on how to proceed given the following:I execute an SQL statement, such as select * from MyTable where FieldX='aaa'An exception happens. Now I need to attempt to determine what went wrong:1. Cable was cut2. Syntax error in SQL3. PC where SQL Server is running crashed4. Timed outI need to attempt to recover from this issue. I have basically 2 options: It is a glitch that self corrects after a period of time, so I can just go ahead and retry the operation a few times. Option 2: It is something permanent, so no matter how many times I retry, the error will persist.
View 3 RepliesI have a tabcontrol that creates tab pages from a "User Control" I created (a separate form in vb.net) using this code: (MainTab is the separate user control I created which has text boxes etc in it)
Dim tmpTab As New MainTab
myTabControl.TabPages.Add()
Dim tmpTabCount As Integer = myTabControl.TabPages.Count
myTabControl.TabPages.Item(tmpTabCount - 1).Controls.Add(tmpTab)
myTabControl.TabPages.Item(tmpTabCount - 1).Text = "Untitled"
I'm using the devexpress xtratab control so the code might look a bit different than the default vb.net tab control.
Now in my MainTab user control file file, I can't for the life of me figure out how to call a control in the form1 where the xtra tab control is placed on. "Me.Parent.Dispose" works for closing the tab when executed via the MainTab control, but that's as far as I can get for communicating with the parent from.
I'm not sure if I have to reference something in the MainTab user control or what in order to communicate with any objects on the default form1.
I'm using DevExpress 2010 vol 1, VS2010 and VB.NET. In my form I have a xtraBar which is used to create the application main menu. Each of the menu items were carefully captioned using the ampersand char (&) to create the keyboard accelerator key, so when user press ALT key and hit the accelerator key the menu is shown. The problem is I can't make the underscore show in any caption. For instance, my first menu "File" has caption "&File", but the "F" is never underscore, and pressing ALT + F doesn't work either.
