I have a question, I have a combo box, which when changed fills the data grid. Now Wen I change the Tab and come back to same tab again(one containing the combo box)..the value of combo box remains there, however the grid gets empty. I need this data to be maintained till the user selects another value from drop down.
View 1 RepliesI am using Visual Basic.Net 2003 with an Access 2000 database.
An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.
1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.
2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.
Data retrieve successfully in the combo box. But first look on combobox is look empty until i click the side button of combo box. I want that combobox show first line of data without click the side button.

View 8 RepliesTry something along these lines:
TextBox1.Text=(dt1.rows(DataGrid1.CurrentRowIndex).item(0).tostring)
where dt1 is the datatable you're using as the data source and you want the data from the first column of the grid to be shown in the text box.

I have two grids inside a TabItem and in the code-behind I want to be able to add controls to both grids and have all the controls visible at run-time. Currently at run-time the controls added to "Grid3" are not visible while he controls added to "Grid4" are visible.The overlapping grids have the same rows but a different set of columns.I'm trying to do this with two grids so that I can vary the number of controls I can add per row in the code-behind by adding the controls to one of the two grids.Here's the XML:
<Grid Name="TabControlGrid" Margin="20,171,0,70">
<TabControl >
<TabItem Header="Tab1" >[code].....
The controls in the XML are just place holders for the controls I am adding to the grids in the code-behind.
How are crossword puzzle grids made? I have written a program to generate a puzzle, my problem is the GUI part.I ended up using Visual Basic (VB) because I'm more familiar with that language.However, eventually I have to write this in Java. So far the only way I am displaying the results in a grid-like format is using two controls Groupbox with a Label inside it.This way I can put the number to the word's clue in the title line of the Groupbox, and the individual letter in the Label. To make the cell in the grid editable (my goal for a different version of the puzzle), I guess a Textbox would have to replace the Label.The GUI for real online (professional) crossword puzzle grids is much nicer than this.I know there is a way to combine controls to make a customized one. Even if this works in VB, I'm not certain if it can be done in Java, therefore, I really don't want to go that route (unless someone knows how make customized controls in Java). I have searched the net and looked in books on games, VB and Java with no luck.I need something that I can grow dynamically depending on the grid size needed to hold the content.

View 2 RepliesI am trying to use a grid to display datasets. The database that I am using is not on my local machine. I have to dial in and log in to the database. We are using an image database. I was shown by my boss that he uses MSFlexGrid, but it appears that is no longer available on the newer versions of Visual Studio (he is using VB6). I was wondering if there was a way to display these grids without going through the Data Sources?
View 4 RepliesI'm curious what we all are using to display grids of data.I keep falling back to LISTVIEW's in DETAIL mode - they visually look nice to me. But I'm always writing code to load them from datatables and such - lots of work.DATAGRIDVIEW's - not so nice looking. Of course we can edit them easily - and they bind really easily

View 1 RepliesI have a bit of a weird issue. We use DevExpress controls to do all our Windows Form development. Anyway, I found a perfect use for the DataRow.SetParentRow/GetParentRow methods in my grid. So I created a DataRelation, added it to the DataSet and bound it as the data source for my grid. The issue is I now find this:On my grid. It seems to be the DataRelation (when I mouse over it the tooltip is the DataRelation name).
View 1 RepliesI have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).
I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

I have been trying to find and/or think up a way for data to automatically update a data table.I have a log that shows all the customers that came in today with various information. There could be twenty or thirty employees adding to this log or updating or doing things with that customer. This information is in a Data Table on a ASPX page in Visual Studio 2010 that the code is binded in the aspx.vb page that is calling a page in my APP_CODE database file that calls a query in my Database to get the information.My question is could someones actions on a different computer make my computer refresh or to re-bind that data.I have thought of some kind of timer/counter maybe that looks to see if the count of the log is different.
View 2 RepliesThis must've have been asked before but I couldn't locate it. In a mixed code project (VB and C#) we were debugging some old Visual Basic code where a statement as follows could be found:
If Request.Params("xxx") <> "" Then
'do something
I considered this a bug as Request.Params could be null, in which case the statement would've become false which wasn't the idea. So I thought. I just found out, -- probably for the tenth time and I will keep forgetting -- that the following two statements are not equal, while Nothing in VB should be equal to null in C# (thought I):
if(String.Empty == null) // always false
If String.Empty = Nothing Then ' always true
Should I dismiss this as a typical Microsoft backward compatibility effort, or should I consider this a huge error in the VB.NET compiler? Does anybody know the Microsoftean opinion on this oddity?
