DataGridView / ComboBoxCell - ComboBox Display Nothing Until It Is Clicked On And Selected?
Mar 9, 2011
I am using vb.net 2010 and winforms and DataGridView. The DataGridView has a DataGridViewComboBox column. When I show the form with the DGV it shows this and empty grid but the column that contains the ComboBox shows the first item on the dropdown list. How can I have the ComboBox display nothing until it is clicked on and selected?
I am trying to display a record in my datagridview based on the value selected from a combobox. I tried the code below using SQL Management studio and it works perfectly.
I've been programming for a while now and I have a Datagridview which is databound. It pulls up a list of my line items and that works fine. So I have: OrderID, OrderType, OrderNumber, OrderDescription Anyhow... these fields all come from the OrderDetails table. I have another table, AllOrders, where one OrderID can have multiple OrderNumbers.
What I need to do is: 1.) The OrderNumber column should be a dropdown list of all OrderNumbers from the AllOrders table where the OrderID matches. 2.) This column should also let users manually type in a value and it saves it to the list. 3.) When the user clicks a save button on the form I need to be able to reference the values from each row to save the selected value to the OrderDetails table.
I thought this would be something rather simple... and I've been pulling my hair out for days. Sometimes I can get the dropdown to load the OrderNumbers correctly, but I can't add one. I can get a ComboBox cell where I can add a value to the list, but I can't load the existing OrderNumbers, etc.
I have a Windows Forms DataGrid currently filled with text.What I want to do is have a ComboBox appear in a cell when the user enters it.After the user has chosen their item from the ComboBox list I want the ComboBox to be removed leaving just their selection as text in the DataGrid, when they leave the cell.
As part of a user interface I'm designing, I'd like the user to encounter the following: when the user wants to edit a value in a cell, the cell in the DataGridView is replaced by a DataGridViewComboBoxCell. This is working now, however, when the user enters the cell (edit cell) the edit cursor stays there, and the combobox won't show. When the user leaves the cell, the Combobox shows, and after again entering the cell and clicking on the combobox, the dropdown finally shows. So 6 clicks are necessary, and I'd like to reduce this to a maximum of two clicks.

This is my code:
Public Class Functions: Public Sub ComboBox(ByVal source As System.Windows.Forms.BindingSource, ByVal MainView As System.Windows.Forms.DataGridView, ByVal valuemember As String, ByVal displaymember As String, ByVal row As Integer, ByVal column As Integer)
I am working on WPF application. I have a window which has "Combobox" and "Textboxes". Well,I want to display the selected combobox values in textbox. (Combo Box displays the concatenated string firstname+lastname+initials).But I have two text box for firstname & second name. I want to display only "firstname" in first text box and "last name" in second text box.I wrote the below code. IT displays the values but concatenated. IS there any way I can just display first name in first text box and last name in second text box.
I have a form with a ComboBox, two labels named "Price" and 'Dealer Cost" respectively a NumericUpDown control and two buttons named "calculate Commission" and "Enter Another product" respectively.I want to be able to retrieve the corresponding Price and Dealer Cost from the local database and display them next to the labels when a product is selected from the ComboBox.[code]...
I am very new to programming, I have developed my first application - an xps viewer. What I want to achieve is to be able to allow the user to select which document to open from a range of options that I have predefined in a combo box. I've searched all over the net and can't find an article that shows me how to do this. MSDN is bit too cryptic for me at this moment, so I get confused. PS> I think I'm using the FixedDocumentViewer (hope I wrote it right).
I have a combo box that has a drop down list with long values in the drop down Ex:
LB - Pounds GR - Grams
When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows
LB - Pounds GR - Grams
When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

I'm loopiing through a datagridview and I want to get the selected value in a combobox, not the bound column's value. (I'm putting the contents of the dgv on a Word document.)
For icounter = 0 To Me.ConversationTblDataGridView.RowCount - 1 range.Text = range.Text & Me.ConversationTblDataGridView.Rows(icounter).Cells("PersonID").Value <-- I want to change "Value" so I get the displayed value, not the person's id range.Text = range.Text & CHR(13) Next icounter
It will not take .DisplayMember or .SelectedItem and .Selected returns True of False. Can anyone tell me how to get the name that shows in the combo box instead of the id number?
I can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.

For example i had three textboxes (txt1, txt2, txt3) and the datagridview had three columns (name, surname, address). The datagridview in connected with an access database using oledbconnection. So i wanted to select a row and then display the selected row in there respective textboxes. The name goes in txt1, the surname goes in txt2, the address goes in txt3

I'm working on a project. Part of the project needs me to capture data, for example, email address, from certain rows/columns of a datagridview and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). I am familiar with doing these in web form but windows form are different and i am not familiar with it.
How to setup a datagridview to display data based on a combobox value, then query the data on that value to display the results in a datagridview. This is what i have so far but i'm sure the is a better way of doing it. the current code doesn't work. [code]...
Note: Combobox contains company name, then when i select one of the company in the list, the information on the table connected to to the company table like purchase order table info will appear on the datagridview.

In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Button1.PerformClick() Button1_Click(Nothing, Nothing)
I have a problem regarding listview control in asp.net and vb.net.

There's a link in a listview where users can click to view a file.I want to get the selected value of each item in a listview after the user clicked the link.
How would I go about changing the color of a line of text in a Listbox when the user clicks a button? I have tried using ListBox1.Items(ListBox1.SelectedItem).Forecolor = Color.Gray, but I receive the error "Conversion from string "Mathematics 1" to type 'Integer' is not valid."
