I want to be able to create the checkbox control object in a gridcontrol and place it in every cell in a column because it has the functionality
I need with optional text built into the control. Does anyone know how to do this using vb.net, not C#.
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.
View 1 RepliesI 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.
View 1 RepliesI 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 RepliesUsing 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 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.

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've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......

I need to change the cell type of an unbound datagridview ROW to checkbox type at runtime. Optionally adding a row of all checkboxes or changing the default type to checkbox is also fine. I see many examples for setting a column type to checkbox but I don't see anything that operates at the row level. Even operating at the cell level would be fine.
