Changing Styling Of DataGridViewComboBoxCell From DropDownList To DropDown?
Nov 20, 2009
I have a DataGridViewComboBoxColumn, and want to switch the style of the ComboBox control between DropDownList and DropDown (mainly for the text field editing capability). I'd like to do this on a row-by-row basis (at the DataGridViewComboBoxCell level).How would I do that programatically? Or maybe a different way of asking: How do I access the ComboBox control given an object of type DataGridViewComboBoxCell?
Given a datagridview, using complex binding I have a datagridviewcomboboxcolumn that displays data from a different table. My question is: when the dropdown list of the comboboxcell is shown is it possible to display a different text than the DisplayMember, lets say more detailed?I search for a solution but could not find any.
Dim cListItems As New System.Collections.Generic.List(Of Combobox_values) cListItems.Add(New Combobox_values("One", "1")) cListItems.Add(New Combobox_values("Two", "2"))
I am developing a VB.NET ASPX file in VS 2008. I am having trouble retrieving the selected input parameters however. This is real simple problem. Here is my current code:

This is a really basic question. This code currently sets the dropdownlist like I want, but just doesn't return selected month and year. How can I fix this?Note that Main2 sub is for PostBack = True.
i want to create a dropdown list which depend on each other. as example. the 1st dropdown list will let the user to select the type between sector or subsector.
select type: 1) sector 2) subsector
if the user choose sector, the sector value will be appear in the dropdownlist
this shall populate the dropdownlist data, but in the value i need it to pick up the "ID" field from the stored proc. the stored proc sends two parameters, ID and Name. so i populate name, but how do i populate the id in value like this -
I am developing desktop application using vb.net and vs2008.I have a DropDownList that I don't want it interact with use when the info is locked. But if I disable it, it is greyed out and the text is not easy to read.Is there any way to make radiobutton like readonly textbox?I want text of the DropDownList looks black and itself is not clickable.The above shows a disabled DropDownList with greyed out text and a readonly textbox

I'm trying to make my datagrids datasource change when you select a particular item from a drop down menu but all I get is blank cells! any ideas? I don't think it is changing the colums property automatically either.
If chooseType.Text = "Add / Edit Players" Then updateDB.DataSource = PlayersBindingSource
How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically. VBE 2010, and I'm hitting an AccessDB
I'm not sure how to go about making my menus and context menus to look like the other menus and context menus in vista.I thought the style would automatically be inherited from vista, but it seems not - and I can't find any sort of 'style' option anywhere either.The image on the left, is what I want the style to be, on the right is what I don't want it to be.
In my windows form, I have a button with a shortcut code using &. It looks like below:
It Text property has the value &Sales Bill - Cash
See that its default styling for the highlighted shortcut code is an underline. Instead, I would like to change that styling to Underline + Bold + Different color

Important:-This whole ddl n chk box are in updatable panel,button is nt in that.I want a browser compatible code so javascript can't b used directly(cz they give problem in mozzila and chrome).Right now, i have done this JavaScript and its is working fine.
function window.onload() { DisableProperty(); }

I have a list of servers in the first dropdown. I want to get list of all databases in the second dropdown depending on the server selected in the first dropdown.
For this I need to query each server while selecting the server.
I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table
I have a DataGridView bound to a DataTable which has an Int16 DataColumn. The DGV has a DataGridViewComboBoxColumn tied to the DataColumn.
I enter integer values in the Items section of the DGVCBColumn properties. When I run the program I get "DataGridViewComboBoxCell value is not valid".
I assume this is because my Items are text and the data column is integer so I created a List of Integer, added my integer values/choices to the list and made the List my data source for the ComboBox column. Same error.
I then created another DT in the DS with one column type Int16, added my integer choices to the DT, created a BS for the ChoicesDT and set this BS as the DataSource, the column as the DisplayMember and the ValueMember. Same error.
There are no issues like this when the DataColumn is bound to a ComboBox outside of the DGV so I assume there is some issue with the DGV understanding the underlying binding.
The problem I have now is that I can not get the value selected as a combobox, I'm trying to set the text and value to each item in the combobox of each cell in the datagrid.
On a form I have a DataGridView. Inside this DataGridView i have several columns of which one is combobox and the others are textboxes.The combobox column is populated with values from a MySql database table using a query. So far so good. What i want next is to populate a certain textbox from that DataGridView, automatically after a value from the combobox is selected. When a value is selected from the dropdown list of the combobox, that value is used in a SQL query to find the value that will be displayed in the textbox.All the textboxes and the combobox are inside the DataGridView!)I did this using DataGridView EditingControlShowing event because a DataGridViewComboBoxCell does not have aSelectedIndexChanged event.The value is displayed correctly in the textbox, but the problem is that the value selected from the combobox disappears after the selection, and the combobox remains empty. I need the value to remain in the combobox after it was selected and after the corresponding value was inserted in the textbox!Here is the code for this:
Code: Private Sub test_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Populating the combobox
I have come accross many scenarios of handling datagridviewcombobox events, however none seem to fit my scenario, or I may be missing something.1. I need to capture the column index that the combobox is resident in. This is because I have a complete row of comboboxes that should set the header text to the selected value.here is the code I have so far:' I also use a list of string as datasource publicly declared
Public cs As New List(Of String) 'to insert the combo's into the grid Dim row As New DataGridViewRow cs.add("Book") cd.Add("Author")
[URL]..But I can't design a solution. Could anyone try to help me out here? I know there are some workarounds to be found, but either the links are dead (check above link) or it's writter in a language I still can't read. Here's my code.
I have a DataGridView with two DataGridViewComboBoxColumns. I want to use the selected item in the first column to trigger a re-population of the items in the second column, on a per-row basis.
Here's the code I have so far. "addlInfoParentCat" identifies the first column, and currentRow.Cells.Item(1) is the DataGridViewComboBoxCell that I want to re-populate. ExtEventAdditionalInfoType is a type I defined that contains the string/value pairs.
Private Sub dgvAdditionalInfo_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvAdditionalInfo.CellValueChanged Dim currentCell As DataGridViewCell
I want to have a DataGridView that has two columns.The first column will always be of type DataGridViewComboBoxColumn. Based on the selection in that column, I'd like to be able to change the corresponding cell in the second column to either a DataGridViewComboBoxCell or a DataGridViewTextBoxCell.I'm thinking I just need to make the second column of type DataGridViewColumn, but don't understand the mechanics of how to change the cell type on the fly.I'm working with VB.NET in Visual Studio 2005.
Update: One way around it, I suppose, is to make the second column as a DataGridViewComboBoxColumn, and change the attributes of the cell so that it either behaves like a drop-down list, or as an (editable) drop-down with no elements. The latter looks enough like a text box that I could live with it, and it wouldn't involve changing the type of the cell.
I'm getting some data from a database and I'm setting them to a DataGridViewComboBoxCell. I also need to set the Tag property of each DataGridView ComboBoxCell item to a specific value, so later, I can query the DB with those two items.The issue, is that I can't seem to figure out how to access the DataGridViewComboBoxCell Item's Tag property.[code]I wrote it on the spot and it wasn't until later that I realized that I'm setting the Tag property of the DataGridViewComboBoxCell itself and not the DataGridViewComboBoxCell's Items.
I have a TextBox column in my DataGridView. When the user clicks one of the cells in the column I turn that cell into a DataGridViewComboBoxCell and fill the items using the columns Tag property which is a 1-dimensional array with 3 items. This is what my Tag looks like:
?CType(sender, DataGridView).Columns(e.ColumnIndex).Tag {System.Array} (0): "" (1): "No Reportable Result"
I am using VB 2010 Express to create a windows forms application with an unbound DataGridView. The DataGridView has multible columns, two of which are ComboBox Columns. I would like to make the borders of the cells be bold when selected as some type of indication to which cell is the current cell. It is possible that I overlooked something completly but I could not seem to find a property that would allow this to happen.
My solution was to create a custom class which inherits from the appropriate DataGridViewCell type (e.g. DataGridViewTextBoxCell, etc..), in that class I override the Paint sub. There I check the selected property and draw a rectangle using the cell bounds.
This works with every type except the DataGridViewComboBoxCell. On the columns of this type I receive an ArgumentException on the call to the Paint Sub. Even if I just have an empty class that only inherits from the DataGridViewComboBoxCell.
Again, it is quite possible that I have overlooked somthing and am making the a lot more complicated than it needs to be.
