I have a datagridview with 1 combobox and 2 textbox. In combobox I show the description. I want when the user update the combobox the program fill the first textbox with the VALUE of the combobox. I have the code to take back the description of the combobox but I don't know how to take the value of the combobox.
Private Sub dataGridView1_CellValidating(ByVal sender As Object, ByVal e As DataGridViewCellValidatingEventArgs) Handles Movement_roller_DDataGridView.CellValidating
Dim headerText As String = _
Movement_roller_DDataGridView.Columns(e.ColumnIndex).HeaderText
' Abort validation if cell is not in the CompanyName column.
[Code] ......
DataGridView TIPs has TextBoxes and ComboBoxes in it and the data comes from an SQL table. I see how to get or set the cell values that come from the ComboBoxes using Item, but how do I access the actual ComboBox events and properties?
how will I find an item that's in the combobox that everytime I pressed the keyboard it will be automatically displayed in the combobox?for example I have Items like cats,pigs,dogs in the textbox then when I press d or do the Items dogs will be displayed.
Controls: textbox, combobox and button I want to have a condition to find out if the value I enter in the textbox exists in the combobox. The combobox reads a text file.
This is well documented and easy to accomplish in Access, but how does one accomplish this in Visual Basic 2010 on a form designed in Visual Studio that is bound to a SQL Server database?
The idea is to create a combobox that holds 2 columns - a primary key value and a unique value such as a [Company Name] or a [Student Name]. The user would then find the appropriate record within the combobox and the code behind the combobox control would then perform a .findfirst method that would NOT filter out all other records, but would rather use selectedvalue primary key column value to move to the selected record.
I am currently getting into VS 2010 & revisiting VB having been programing in ACCESS & VBA for years. In the Access/VBA environment it is very common to have to find a given record on a given form using this method, but it would appear to be poorly documented if in fact not commonly used in the VB.NET/VS community.

I have combobox column in datagridview.I have loaded a particular database table column value into it from my mysql database. The combobox in all the rows is filled with my database value successfully.But i am unable to select values from it.
And my second problem is I am unable to retrieve the penultimate row values in datagridview before the new row which is automatically generated.The error for it is nullpointerexception. But i have values in that row.
I have a combobox on a datagridview on my form. The problem I encounter is I have to click the button twice to see the items at the dropdownlist rather than once at runtime. Is there any change I can make probably in properties of the datagridview / combobox to show the dropdown list by clicking once rather than twice..
I though the problem was resolved but unfortunately is not.. I added this code to my form; Me.DgvReturns.Item(6, 0).Value = Me.DgvReturns.Item(5, 0).ValueThis Only affects the first line of the datagridview.. The second, third, fourth etc etc records are not reflected. Therefore, the vale of the textbox is not shown on the combobox.
Is it possible to have a column in a Datagrid with Only one combox at the second row and rest of the column remains empty ?.. means I want to have only one combobox at the 2nd Row and nothing else in that entire column...
i have seen the message describing the problem where the autosizing of the combobox column in the datagrid view will cause an error stating "datagridviewcomboxcell value is not valid"
I am using visual studio 2008, vb.net Windows app and ms access 2003.I just wanted to know that there is a form in which i select an option from the list of options in combobox.. While the user selects a type, i want the data relevant to the type be displayed in the datagridview. I have bound the datagridview to datasource in design..But am blank as to which event can i use and how should i start it ?? Went through various sources, but seemingly vague.
here is what i'm stuck with i have datagridview and datasource is dataset. Everything is fine no problem.
It has 3 coloumns, ID, Name, City. ID is PK Now I have rowfilter on dataset like this
dataset.tables(0).defaultview.rowfilter = "Name Like '" + txtName.text + "%'" everything is fine till here. it show selected records. now, i have another text box on form which ask for id and search id in datagrid like this dim dr as datarow = dataset.tables(0).findbyid(cint(txtId.text)
in above case if id found then it will dr with row. which is fine. the question is how i can find if current row is in list or not because of filter on dataset.table
I have a datagridview which have a ComboBoxCell, ComboBox is bound to data,, I want to use it as Traditional ComboBox,, I mean I want to display its Item (from display members) on the base of its value.
For example: When I do this Datagridview1.CurrentRow.Cells(4).value = 4 'Cell 4 is the DatagridviewComboBoxCell
It gives me the error that "DatagridviewComboBoxCell.value is not valid",
But I want that this combobox should Select And Display the item which value is 4.
I am trying to add a combobox into my datagrid which connect to access database by using the code below. The result I wish to get is the combobox is locate at my datagrid column that already exist, but what I get now is it will add a new column with combobox that I want to add. Can I just update the combobox into my existing column7 but not a new column?[code]...
I bound a column ("Initials") of DataGridView (which is bound to dataset ds) to dataset ds2 ("employees"). This part works fine (comboboxes appear loaded with employees initials in combobox selection), but theere is no default value in the column. Do I have to add some event handler or binding stuff??
Because there was no aswer in Windows Forms General general forum i decide to post the same question in here... is about cascading comboboxes in vb.net.. Could somebody give me a guideline how to stop previouses selections of dissapearing when another selection is madein a new row... [URL]
I am trying to have cascading comboboxes within a datagridview.I have it partially working. dataset1 has 2 tables, with a parent-child relation built inDatagridview1 contains:column 1: combobox, bound to bindingsource 1 which is bound to dataset1column 2: combobox, bound to bindingsource 2 which is bound to bindingsource 1when column 1 is selected, column 2 choices are limited to those related to column 1however, if column 2 is chosen in a row that previously had data, and was loaded with the form, then its choices stay the same as the last row where column 1 was physically selected before column 2.I seem to need to refresh the binding source somehow to emulate how it works if I was to go into column 1 and make a selection by hand.H
