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".
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
Private Function LoadSupplierData()

I 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.

View 6 Replieswant to make a custom calendar. For that I made a table of 7 cols and 6 rows and added 42 buttons in it. I added an event handler. I used this file in other form and when I click at the button the event is fired in form2. I understand this is not hte efficient way to add so many buttons. As it is a calendar, so I got to add dates to buttons based on month selected.I am finding that part difficult. For this feature, I think I should add buttons dynamically. But I can't make out how to add buttons to each cell of the table. Later on each buttons text will also change. I have added the code written so far :
Public Partial Class CalendarControl
Inherits System.Web.UI.UserControl

how to focus a particular Row in devexpress
View 4 RepliesI want to add CheckBox at DevExpress's xtraGrid columm so for this what should i do
View 1 RepliesI 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.

I currently have a DevExpress GridControl where one of the columns have a GridLookUpEdit assigned under ColumnEdit. Yet when I run there is a column name (the display member) that shows up.I know with a LookUpEdit you can set the column headers to invisible with lookupedit.Properties.ShowHeader = False but I have no clue how to make it invisible for the GridLookUpEdit.
View 3 RepliesI have been working in Visual Studio which has DevExpress. My project now doesn't recognize DevExpress so I now have 102 errors on lines like:[code]...
In addition to this when I try to go to the designer for my DevExpress report it can't load the designer :
"The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: rptAll --- The base class 'Object' could not be loaded. Ensure the assembly has been referenced and that all projects have been built."
Yet when I look in my toolbox the DevExpress tools (XRLine, XRLabel...) are still shown and DevExpress is still located in my reference folder.
I have a custom EditButton that shows a dialog for the user to select a value.This is used by an xtra grid as an editor for a cell.The user can click the cell editor, the dialog shows and they can select the item they want.

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.
