I am using datagridviewcombobox column for the first time bound to a datasource.I have set the datasource, DisplayMember and ValueMember. The DGVcombobox is getting filled up from the datatable column content without any problem but unlike a normal combobox, it is not displaying the first item as the default text from its list.
So My question is how to display the first item, from the list as the default text so that the user don't have to select an item from the list for every row.
I am searching again and again but without any success, Please help me. Thanx.
I have a bit of a dilemma - in the ComboBoxColumn, I have added various numbers from 0 to 11. I need people to be able to type into the ComboBoxes in that column if the Combobox doesn't contain a value they need.I realise that I have to change the ComboBoxStyle to DropDown but am not sure how to. Also, for each row in the ComboBox, I believe I have to add the item that the user typed to the ComboBox list items for it to save but am also unsure how to do it.
I have one DataGridViewComboBoxColumn in the DataGridView, and that column's "ValueMember" is the "id" and "DisplayMember" is the "name" of my table. When I try to read the text with cell's "value" property, the "id" is returned instead of the "name". Is there a way to read the "name" or "DisplayMember" of a cell in DataGridViewComboBoxColumn?
How can I make my text box go to the enterd web address, through the user's default web browser?(And not by creating an actual web browser in the application..)
I'm working on a project for my VB class at school. I am creating a form with several inputs and it calculates the total amount owed for a car sale. I have a text box for input of the TRADE IN VALUE of a car. the program is looking for a numeric input. If there is no trade in, how can i get this box to default to 0.00 so it doesnt error the program?
I want to modify the default Object text size for all objects I place on my form. When I am teaching, it is hard to see the text on the objects. I have changed the code area to 16 pt, but I have not seen how to modify the default font size of the object. They all are 8.8 pt.
I have a combo box that contains installed printers on my system, a combo box that has the text file I want to print, and a print button I have created. I am trying to find an understandable way to select the file I want to print, then select the printer I want it to print from, and be able to click the print button.
How can I assign a value to a message box for when the default value displayed in the text box is unchanged. ie. If my default value is 17 and the user clicks ok without retyping a number, the Input value displayed in a textbox will be 0.
Currently I have:
Public Class Form1 Dim MyValue As Double Private Sub But_EnterInput_Click(sender As System.Object, e As System.EventArgs) Handles But_EnterInput.Click MyValue = CDbl(InputBox("Input a value", "Data Input", "17", 200, 400))
[code]....
This works however if the user types 17, the textbox will read 0. not what i want.
So i have this code that changes the size and the font of the text but my problem is that how can i make the font and the size of the font to return back to default after it runs this code.
ListView1.Items.Add("Found Files In C: ")
My code
Dim Font As Font Font = ListView1.Font ListView1.Font = New Font(Font.Name, 32, FontStyle.Bold)

i have always seemed to have found the default windows notepad useful. no matter what type of app i create that saves, edits, and does everything notepad does plus tons more, i always seem to end up using notepad one way or another.. until recently..
i finally designed my own custom notepad. pretty much all the features, minus a few, and plus a few.. i like the new features. ;o)

I have a datagridviewcomboboxcolumn which has its .DataPropertyName set to a int field, its .DisplayMember set to a nvarchar field and its .ValueMember set to a int field on a lookup table. I have captured a dataerror which states that the control is trying to push the .DisplayMember(nvarchar) to the .DataPropertyName(int) field. When I load existing data it works fine. When I try to leave the datagridviewcomboboxcolumn after selecting a different value in it or leave it when I add a new row, I get the error. What am I doing wrong?
