Dropdown - Adding A Dataset Inside A Datareader?

Mar 3, 2010

i am making a table through vb.net code (htmltablecell, htmltablerow..) no this table populates with an sql query and works perfectly. but inside this table in one tablecell, i need to add a dropdownlist which shall require a completely differernt query and shall run on its own on each row. so the code is as follows

Sql = "..."
rd = ExecuteReader(SqlCnn, Sql)
Dim newcounter As Integer = 0
While rd.Read()

[code]....

the ??? in the code is where the dropdownlist shall get populated each time with its own datareader and while loop and query.

Make The Value Of The Datetimepicker Change To What Have Clicked Inside The Dropdown Calendar?

Apr 15, 2011

I've got a datetimepicker control on a vb .net 2008 form. I have set it to show a custom format of "dd/MM/yyyy". The problem is this: - when i click on the arrow button, a small calendar is shown in which i should be able to select a date. The only way i can do that is by using the arrow keys and pressing Enter. Clicking on any date value inside this calendar doesn't do anything.How can i make the value of the datetimepicker change to what i have clicked inside the dropdown calendar?

Excel - Adding Items To Ribbon Dropdown?

Apr 12, 2012

how to add further items to a dropdown control on the ribbon.

So far I have been able to create a number of items manually and then afterwards change the label of these items using

Globals.Ribbons.Ribbon1.DropDown1.Items(i).Label

Furthermore I found that some recommend using this to add further items to the dropdown control. But I am having a hard time trying to understand how to use it.

Globals.Factory.GetRibbonFactory.CreateRibbonComboBox.Items.Add

I would like to see a sample of how others have done it.

VS 2008 Dynamically Creating And Adding Dropdown Controls To DevExpress XtraGrid?

May 6, 2011

I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements

this is what the code looks like:

vb.net
Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit
For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1
column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp

[code]....

The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.

Keep The DGV Inside The Group Box When It Is Not Bound To A Dataset?

Aug 30, 2009

I have a DGV which I am laying out in code as it is unbound. The problem I have is when it is inside a group box, it moves outside the group box to the top of the form.

If the DGV is not enclosed in a group box it stays put. I have tried docking the DGV to the group box but that does not work. If I have a dataset bound to the DGV, then there are no problems.

How can I keep the DGV inside the group box when it is not bound to a dataset?

Adding To Listview Inside Tab Control Without Knowing The Name

Sep 23, 2011

I have a tab control, that the user can add/remove tabs as they please. It is an inventory manager, and the tabs are the departments. Everytime a user adds a department, a new listview is cloned and added to the page. Upon form load, i need it to go through the tab pages, and query the database for items matching the department their in. In other words, if the Department column in the inventory database, matches the Tab Pages text, add it to the listview inside that particular page. I've tried several things, but they all end up buggy. Either it adds them all to the first listview, or it skips every other page, or worse - doesn't add anything at all. Here is the code I have, could anyone help me figure out how to:

Cycle through the pages, if any of the DB's rows Department column matches the tab page text, add it to the listview inside that tab page, then move to the next tab page, and cycle through the DB again. Here is my code, a decent start I believe.

Sub FillList()

Dim incs As Integer
Dim inc As Integer
Dim lst As ListView

Enum Inside Structure - Adding Properties?

May 19, 2009

I have an enum that I want to give some methods. I thought about changing the enum to a structure so I could add properties, but then the enum is a value inside the structure (not the structure itself), so this would affect comparisons and such. (For example, instead of writing
EnumVariable=EnumConstant,
Now it is
StructureVariable.EnumValue=EnumConstant).
At least, this is my understanding of it. It seems awkward to have to do this for such a simple scenario, so is it possible give enums properties, yet still have them treated as before? I've thought maybe I need to create a new valuetype from scratch, but I've never done that before.

VS 2010 - BindingSource And Dataset - Show Attributes In Textboxes Inside A Form

May 16, 2011

[Code] Somewhere my system haves a function that returns a DataSet with the books of a certain subject and all the Authors that wrote such books. I need to show the book's attributes in some textboxes inside a Form. I use a BindingSource to display the ISBN, Name and Subject of the books in a textbox, yet I don't know how to display the author name of the book I am currently viewing in a TextBox, taking into account I already fetched the Author into the DataSet.

Its pretty much the Child/Parent display problem somewhere discussed in the codebank, but kinda backwards, the thing is that I;m navigating through the CHILD records here, not the parent, yet i have all the data needed in my Dataset.

User Control - Adding Internal Labels Inside It

Mar 8, 2010

I've made a user control and have added some internal labels inside it. In the User control class I'm trying to handle the mouse events so that: When the mouse enters the User-Control the background of the User-Control turns white - using MouseEnter event. When the mouse leaves the User-Control the background of the User-Control turns grey - using MouseLeave event. However as soon as I move the mouse over the internal labels it triggers the MouseLeave event. I don't want it to do that, because the mouse hasn't left the bounds of the User-Control! So, how do I get it to not trigger the MouseLeave event when the mouse is still internal to the User-Control?

Adding Line Number To A Dataset?

I have a dataset that is being populated from a text file.

123,john doe,product1,20.99

There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?
