Remove Selection In Combobox2 If Selected In Combobox1?
Oct 9, 2009
I want to learn how to populate a combobox so if a vlaue is selected in another combobox then it will be invisible for selection. You can NOT use combobox1.items.remove since my box is bound to a datasource.So I either need to create a new query and adapter and bind the combobox2 to that query, or fill combobox2 from combobox1 minus the selected item in combobox1. Either way I need some help writing code correctly.I have tried a few different ways but not succesful, I was probably on the right track a few times but I am still not very proficent in code writing.This is the code I have written so far for my program, I deleted all my attempts at remove selected item since none worked and were just confusing.
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
OpenFileDialog1.InitialDirectory = "c:\"
OpenFileDialog1.Filter = "CSV Files (*.csv)|*.csv|Text Files (*.txt)|*.txt"
OpenFileDialog1.ShowDialog()

I have one table from where two comboboxes get their drop down lists, showing info that has been entered into the table (boxes are bound to the table columns I.E City (Box1) and Country (Box2). what I would like to do is if a city is selected in box1 then box2 will autofill with the country name.

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?

If you add a list view, then add a column, and an item, set the view to Details and run it, there will be dots around the item. Those dots will also appear whenever you select an item, along with a highlighted color. I've downloaded projects that don't have them, and when comparing I don't see any difference in listview settings between that and my listview... How do you remove those dots?

I know the question is a little choppy and perhaps misleading,but I have a gridview with dropdownlists on the rows. I created an AddHandler and a Delegate for the SelectedIndexChanged and it gets to the sub. Here is the code for that:
AddHandler ddlmgr.SelectedIndexChanged, AddressOf ddlmgr_SelectedIndexChanged
Public Delegate Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As DropDownList_SelectedIndexChanged)
Protected Sub ddlmgr_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
End Sub How can i get the row's Id if GridView_RowCommand is not called?

In my program I've got several comboboxes that all have the same comboboxitems and when the user makes a selection in one of the comboboxes the selected comboboxitem gets disabled in the other comboboxes. (i.e. If the user has selected the comboboxitem with value 'a' in combobox #1 and selected the comboboxitem with value 'b' in combobox #2 then in remaining comboboxes both the comboboxitems with values 'a' and 'b' are disabled)

I am Working in vb.net .The only i found is C# .. "The fuction you want can be called "cascade comboboxes", i.e. there're two comboboxes and the items of the second combobox depends on the selected item of the first combobox. The basic way to implement cascade comboboxes in a DataGridView is to handle the EditingControlShowing and CellValueChanged event of the DataGridView. in the EditingControlShowing event handler, if the column in question is the second DataGridView combobox column, change the data source of the editing control (DataGridViewComboBoxEditingControl) to another data source and filter the new data source.... In the CellValueChanged event handler, if the cell value under the first DataGridView combobox column is changed, clear the cell value under the second DataGridView combobox column in the same row.."
The Problem is this: 2 ComboBoxColumn already with their dataset (via propretries of datagridview design) and the DGV2 is a detailed datagidView Reffered to a Master which is another DGV on the top of my Form. So in DGV2 the first ComboBox 1(column 2) displays data .According to this Data the other ComboBox2 (column 3 ) filtered. The problem is that when you select more than one time the same value of the Combobox1 and then you try to select another value the displaying data of the ComboBox2 dissapears.
keep the values of combobox2 always visible..
Private Sub DGV2_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DGV2.CellValueChanged
If e.ColumnIndex = ComboBox1Column.Index Then

I am using datarepeater to display rows of information from database. When i click a 'save' button and i would like to loop through the rows of data in repeater. The code i am using is able to do all these. The only problem i encountered is at the Interface side. When i am looping the data-repeater. The selection 'frame' (refer to the picture point as 'A') is moving from record to the next record and scrollbar is auto moving as well to scroll to further down until the last row where looping finish.Is there anything can be done to remove the selection 'frame' and stop datarepeater from scrolling while looping the datarepeater.

I seem to be having issues with the selected index on a list box.
The list box is having various items inserted depending on the user selection. An example would be:
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")
[CODE]......................
This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex
I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.

This code seems right but its not working. It's giving me an "Index out of range" error. If I change the upper bound of the loop to "(Count - 2)" the code works, it just deletes all except 1 selected row. So can't figure out why "(Count - 1)" doesn't work.

Is there a way to remove the LineShape shadow effect when selecting the lineShape? I tried
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
Dim g As Graphics = e.Graphics
g.SmoothingMode = SmoothingMode.AntiAlias
Dim oldmode As SmoothingMode = g.SmoothingMode
g.DrawLine(_Pen, X1, Y1, X2, Y2)
g.SmoothingMode = oldmode
End Sub
but finally, this have some back effects on invalidation: when moving (in a panel) the line leave traces - does not invalidate properly.
