View 5 Repliesi want to select the row on datagridview and send it cell's value into textbox / label control on the same form..but it seems not work, but when i use
Private Sub DGV_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DGV.CellClick
it can but i have to choose by click on each cell on it datagridview..what i want is i only have to click on it[datagridview] row but i get all value on it's column.. so i can parse/send it value into textbox.it only can be clicked with single row i knew it by DataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect
i have a DataGridView responsible for showing a bit of data and two of my columns allow for user input using comboboxes.The trouble is that one column only needs to show preset values in it's list, but the other needs to both show the presets and allow for the user to enter in their own values.i accomplish this by showing the editing control for the combobox with this bit of code:
Private Sub DGV_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DGV.EditingControlShowing

I searched a few threads for TextBox number solution and found that most were using e.Handled and e.KeyChar in TextChanged. But I couldn't find them in VB 2008. What can I find in Vb 2008 for the same meaning?
View 7 RepliesPrivate Sub TextBox4_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox4.KeyPress
If (e.KeyChar < "A" OrElse e.KeyChar > "Z") Then
e.Handled = True
End If
End Sub
If e.Handled = True means we can enter a to z and A to Z in textbox.If e.Handled = False then what it means??

I am making a program that uses the datagridview control for making the sales invoice and I want to add direct values from textbox control to datagridview. But the problem is I am not getting the row, col index properly and if I use:
dgv.item(0,dgv.rowcount -1).value=textbox1.text
Then the value goes to the 1st col and 1st row. When I use dgv.rows.add() then value goes down to last row of the dgv control.
I created a table in mySql named 'user' where fields are:
UserID,UserFirstName,UserMidName,UserLastName,Username,UserType,AcctPassword,DateCreated, DatLastModified and IsDeleted.

I have a list of customers (over 50k) that I am trying to change the way my users search and interact. Presently, they fill in parts of a first name, last name, home phone field(s) and then click a button and it searches and presents a listview list to the user for selection of the one they are trying to find. Fairly straight forward behind the scenes with a customers object making the call to the sql server on the network and returning customer objects as indicated. I want to add a datagridview control and display all customers and then have a textbox for the user to type their selection into and have the datagridview update accordingly.
I want the filter to be dynamic as the user is typing. What I have so far is the datagrid loaded with data and the text box. I also have a stored procedure that takes a string(the text box) and returns the customers collection object as the "new" datasource. But as you are guessing, that is to many calls to the database over the network. Just not very efficient. Once I have the original collection object, how can I filter it dynamically in memory as the user inputs characters into the textbox.
how can I detect if press Enter in the Textbox Change event and not in Textbox Keypress?
View 3 Replieshello,
i'm trying to build a application for my buddy who plays online games and has asked for a simple program to click the mouse button within his game that he plays for a certain amount of time with a certain duration between. my questions comes ( and i searched but didnt find much useful information for .net framework anyway) about how to detect a combination of keystrokes to start an action and further more to send a click event to the game that should be main focus. i'd also appreciate any tutorials on sending information to other forms controls etc.
thank you for any help
I have a datagridview with 12 columns and 30 rows I want to use as a scoreboard for a game (no need to input or save data). Columns are for the players and rows for the scores of each turn played. Say player1 has a score of 10 I type it in in his column in row1, the 10 should show up in a label as his total. His next turn his score is 100, type it in row2 and the label should show 110 as total. Hope I am clear enough, is there anyone able to give an idea on how to do this (in code if possible)?
View 3 RepliesI am automating a datagridview that will hold the name of an object in one column and the number of units in the second column. The datagridview keeps recognising my numbers as a string and doesnt sort them accordingly. Any ideas how to inform the datagridview to sort by numeric?

I am trying to send keys to a control on my form. But I am getting a NullReferenceException and I don't know why. The code is about as basic as it gets: [Code] The error reported is object reference not set to an instance of an object but Send is a shared method so doesn't need an instance. Strangely if I ignore the error it works fine and F4 is passed to the control. I know there was an issue with sendkeys and UAC but I thought this had been solved (I am using 4.0 framework).

Me.DataGridViewTblInvoiceDetailsAndTblTempInvoiceDetails.Columns(2).DefaultCellStyle.Format

View 4 RepliesI have to give textbox control id like below

It is not allowing me. If I give

Then it works fine. Why? Why can not give start with numbers?
I'm trying to create my own numeric textbox that will handle decimal as well as whole number values. The concept is, unlike the regular textbox, this one will accept a value of 'Double' data type and show it with proper formatting e.g. Leading Digits, Digit Grouping etc. When the textbox value is called, it returns the actual 'Double' data type value. The entire thing is done through the 'Text' property; wherein the regular 'Text' property is shadowed and one with 'Double' data type is used.

What's my mistake?
