Two Gridviews Within A Gridcontrol - Cannot Get Focused Row Handle For The Inner Grid
May 5, 2011
Using DevExpress 10.2 within Visual Studio 2008 with VB.Net I have created a single gridcontrol that contains two different gridviews. The gridviews are related using an id column. Basically if there are related details about a row in the first gridview then the user can click on the plus sign to see all the related details. When I have any row on the first gridview I am able to get the focused row. Yet when I have the focus on any of the rows in the second gridview I am unable to get the focused row or the content of the row.
[Code]...
Is there any way to get the value in id from the focused inner gridview? Or at least figure out the parent row and grab the id value from there?
I am currently programming within Visual Studio 2010 using VB.Net and DevExpress V10.2 Winforms. I currently have a DevExpress GridControl that contains two DevExpress GridViews.So there is the main view and the subgrid (similar to the DevExpress demo for Master-Detail Grids - example with WinForms and better view with ASPxGridView). Currently the data for the grid is fetched into a DataSet:
If myDataSet.Tables.Count > 0 Then myDataSet.Relations.Add("Details", myDataSet.Tables(0).Columns("id"), myDataSet.Tables(1).Columns("id"))
I have a datagrid view that loads data from a database. This is unbound datagridview.The columns are Description, UPrice, Quantity and TotalDescription UPrice come from database then quantity is typed. I want it so that when my datagrid loads, cursor goes to Quantity column and it is shown blinking like we have in text boxes.
I have a data grid view with columns created when it was filled from a sql table. some of the data types are "bit" (meaning 0 or 1 and automatically shows a check box in the column of in the data grid view).I need to get a handle of the cell that has a check box in it so that when a check box in one column is checked or unchecked, i can change the status of the rest of the columns (only one column can be checked at a time) and then update the entire row in the sql server..when column 3 in the data grid view is checked, app will uncheck column 2,4,5 run sql statement to update changes?
Is it possible to change the data source of a dropdown list in a gridview from another dropdown list selected index changed method in the same gridview
I am using DevExpress GridControl to display information from my database through a stored procedure (ie. SELECT * FROM aTable). Unfortunately when I run the program it doesn't display any of the information, columns, etc. It displays an empty table. I know that there is information contained by the GridView though as I have print statements that return the row count. Specifically:Console.WriteLine(GridView2.RowCount) ' returns the number of rows that should be displayedConsole.WriteLine(myTable.Rows.Count) ' returns the number of rows that should be displayedWhat should I do so that the actual data within the table (DataTable) and the DataView is displayed to the user. I know the row count is correct as when I add/remove a record the row count correlates by incrementing/decrementing.
I was having a heck of a time populating a gridview combo box.I learned a ton in the last 48 hours but would really like to know the answers to the bottom three questions.You guys are the experts, so I'm hoping you will enlighten meBut the summary of it is below:I was never able to get the ComboBox to bind to the data source. I tried everything until I turned blue. So I went to the basics and coded all the automatic stuff. I'm curious as to why the automatic binding didn't work. Perhaps its because my gridview datasource was LINQ.Here is how I pulled it off. I hope someone down the road benefits from the last 48 hours of my delima:First of all, know that I have two drop down lists on my form, one is the GPField and the other is the BankField. These are already populated DDLs that are static. So I used them to cheat on the values instead of using enums.
Sub fillGPFieldListDDL(ByVal obj As Object) Dim db As New CompanyDataDataContext Dim myConn As New Connection With {.ConnCls = ConnCls}
I have created a site in VB.Net and ASP.Net where a user types in a centre code and clicks on 2 buttons to retreive 2 GridView's of records from an SQL Server backend database.
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:
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.
Im trying to add data into a new column I have created in my gridview.[code]...
Now I need to go in and add data for the rows below the column. I have seen ppl saying I need to set it equal to a datafield but how do I create a datafield from scratch then?
I'm looking for a solution to implement in web apps where I have the option to see a print preview or print either a gridview, datagrid, or datatable or export it to word or excel. What's the best method to do this or has someone written a class that does this, and does it well (I've seen many examples, but many still have errors)?
I'm developing a user control that exports a grid view to many file formats, this control takes the gridview as a property, I need a code that returns the gridviews in the form if so that in design time user can choose one to export
I found out how to keep track of the currently expanded grouped rows by using 2 events: - gridview.GroupRowExpanded - gridview.GroupRowCollapsed
Where I increase or decrement an integer that keeps track of how many group rows are currently expanded. I am now tackling the problem of what to do if the user expands or collapses all of the group rows. I currently know when this is done by checking the e.RowHandle. Any way to find the total number of groups rows currently in the GridView (something like rowcount for normal rows) so I know how many to set the tracking integer to.
For Example: If my current count is 2 and the total number of groups are 15 then when the Expand All is fired the current count is set to 15 rather than 3.
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.
My issue is the print preview always shows all the grouped rows and the master-detail rows fully expanded. I want to make it so that if the user has none of the groups or rows expanded then the print preview displays the grid with none of the groups or rows expanded. Also if the user expands the first group and rows fully then only the first group and rows will be expanded in the print preview and none other.
When I have changed the name of a table field name none of my combo boxes or grid views work properly. The TableAdapter still refers to the original name. Is there an easy way to make the change propergate through the program or do I have recreate all my TableAdapters.
I've created a Gridview control that pulls some data from my database, but doesn't display all of the information I'm hoping it gathers. I choose not to display the primary key for user interface purposes, but require that key for basic operations on the grid.I'm currently attempting to add a "Delete" option to the table, but unfortunately I'm having very little luck. Here's my .aspx file.

This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.
How do I retrieve the name of a textbox that has the focus? I have many textboxes on my form and when the user right clicks anywhere in one of the textboxes I want my code to store the name of the textbox in a string variable such as NameOfSelectedTextBoxString as string.
I am using Dev Express to develop a form in which i have a GridControl with a View inside a View.It looks like this:
I am then trying to use the event ValidatingEditor to validate the user input.I tried to do that by doing:
Private Sub grvObsAM_Artigos_ValidatingEditor(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs) Handles grvObsAM_Artigos.ValidatingEditor Dim row As Integer = Me.grvObsAM_Artigos.FocusedRowHandle
This, however always returns me something like -99999.. I poked around and tried this other solution using the sender from the event:
Private Sub grvObsAM_Artigos_ValidatingEditor(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs) Handles grvObsAM_Artigos.ValidatingEditor Dim grv As DevExpress.XtraGrid.Views.Grid.GridView = CType(sender, DevExpress.XtraGrid.Views.Grid.GridView) Dim row As Integer = grv.FocusedRowHandle
And using this second solution i managed to get the focused row handle. Even though this worked this time (because the event was triggered by the view itself and i had access to the sender) this doesn't solve my problem as there are other events where the sender is not the view and the problem persists.Usign Me.grvObsAM_Artigos."insert anything here" doesn't seem to work properly.
I have a Class(ChorNumbers) and in this class i have a Function that test textbox1...17 is a Character or a Number.I create a WindowsForm that have 9 textboxs. And if i enter 1 in the textbox1 that must jump to next textbox2 (that do this) If i enter A in the textbox2 that must jump to textbo3, but they does not jump. Where is the Problem why it doesnt not Jump?And i want a use one textbox1_TextChanged Function.
I want to beable to make a Form Focused over the over one.E.G. I have 2 Forms Called: MainForm.vb && HelpForm.vb When I Press 'Button1' on 'MainForm.vb' 'HelpForm.vb' Pops-up I want to make HelpForm Focused so that the User cannot continue working on 'MainForm.vb' But when HelpForm is closed i want MainForm to be Enabled again.
Is there anyway for a form to become in focus.. basically something like Me.inFocused = True, In order to print a form, it must be visible and in focus, so I need to focus on it without the user having to click it so that I can send the form to a printer
I am creating a 2D RPG game similar to the pokemon interface. After solving my problem with walls, I came across another problem. If I make the panel show the whole map, it would be too small. Thus, I tried to increased the size to 1200,1200, but it wouldn't let me because my screen is smaller than that. Then I thought about it and realized that most games limit the sight of the map to the characters surroundings.
I have my menustrip with the standard edit items. I know I can do this:
If TextBox1.Focused = True Then TextBox1.Undo() ElseIf TextBox2.Focused = True Then TextBox2.Undo() 'Ect. Ect. Ect.
End If until I type out every textbox. However, I have like 30 textboxes and don't want to type out every textbox to see if they have focus. Is there a work around for that?
