PictureBox Related To DatagridView Row/column Value When Clicked?
May 19, 2009
I have a loaded DatagridView which contains a row/column with an employee number in it. Outside of the DatagridView at the the top of my form I have a small PictureBox. My goal is for the user to select the employees row (not cell),pull the employee number from that row/column, and then use a LINQ query against another table to display the image stored in that table.
Determine the event needed in the DatagridView?How do I pull the employee number from the selected row?What considerations, if any would the LINQ query need to pull the picture from the table?
I'm new to VB.NET BTW. I designed a form and radio buttons and a submit button with a picture box ! Every radio button selected will display the image related to it in the picture box !
So, we have O smile O sad O mad O happy O ...etc When pressing the submit, the selected radio button will display a face of the mood !
Here is my code. If RadBtnSmile.Checked Then PicBxMood.load("smile.gif") End If If RadBtnSad.Checked Then PicBxMood.load("sad.gif") [Code] .....
i have a GridView bound to a DataView. Some columns in the DataView's table are foreignkeys to related tables(f.e. Customer). I want to enable sorting for these columns too, but all i can do is sorting the foreignkey(fiCustomer) and not the CustomerName.
I have tried this without success(" Cannot find column ERP_Customer.CustomerName "):
A tried also the DataViewManager, but i've a problem to detect the table to sort:
Dim daCharge As New ERPModel.dsERPTableAdapters.ERP_ChargeTableAdapter daCharge.Fill(dsERP.ERP_Charge) Dim viewManager As New DataViewManager(Me.dsERP)
I am using the MouseClick event toc change the image of a picturebox when it is clicked:
Private Sub PictureBox7_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox7.MouseClick PictureBox7.Image = Image.FromFile("C:Documents and SettingsjacobscDesktoplogogoclick.png") End Sub
The problem i have is that this tool will be used on different users computers and not just my own and at the moment when it is used on another computer it gives an error that it can'f find the image.
This obvioulsy happens as it is looking for my desktop, how can i change so that the image can be saved within the tool and therefore will work on other computers?
Let's say I have a PictureBox with an image of a house, for example, and I want to know if the user clicked on the roof, the door, the window, or the walls.
Is there some way to, maybe, set up an If statement so that it checks what the coordinates of the mouse click was and compares it to a set of pre-determined graphed points to decide what object was clicked?[code]....
I am using vs2005 with access db. I am retrieving a tables data thru datagridview using an access query. The table i am calling is contains "ID" of something and I convert it thru the query and show it as names for the sake of my users.
My problem is how to store again the related "ID" s after they alter the datagridview cells? (i.e:the retrieved table contains only id's of customers and i showned the users as names, after they are editing how can i convert the user name as "ID" because the field is Long Integer foreign key field) Or otherwise how can i show the datagridview partuclar cell value as combobox style?

I am fairly new to vb.net and the form includes 3 picture boxes in red which you can click and change their color to green, also each picture box have three text box associated with it and they are by default color dark gray. I want the system to check whether the picture boxes are clicked and if yes set the associated text box colours to white.
Here is the code I wrote: Public Class Screen Inherits Windows.Forms.Form Dim T(1, 2) As TextBox Dim S(2) As PictureBox Dim x, i, j As Integer [Code] .....
I am currently creating an app and i want to be able to get the colour of a pixel, but in a picturebox.Example: I click anywhere in the picturebox and it will give me the color of the pixel I clicked.

[code]I'm able to display Data from the tables to Datagridview but how do I update two tables from Datagridview?For some reason under Advanced Options Generate Insert, update and delete statements gets unchecked.
I am currently working on a program in VB that is 480,600 and am using a panel with a picturebox inside of it so that I can use scroll bars to view a chart in the picturebox since my form will be so small. Since viewing a large chart is pretty irritating using scroll bars to some, what properties can I enable or disable to get the panel and picturbox to expand also when the Form Maximize button is clicked rather than staying the same size up in the top corner?
I am trying to produce a form in VB2008 which shows data from two related database tables, and then allows the data in one of the tables to be updated. I would like to do this using a DataGridView, but I have no idea how I would go about this.
i = dgStudentsHandled.CurrentRow.Index txtStudentNumber.Text = dgStudentsHandled.Item(0, i).Value
I can get the value of the first cell of the first row of the first column. But I have to get the value of the first cell of the the first column of the any row index I click.
I'm using datagridview in my vb.net project.

I have a datagridview that I have put a ContextMenuStrip1 on. I would like it to remove a row in the datagridview when the row is right clicked on and they click on "delete row". I have the delete working and the menu is showing up but this isn't firing when you right click on the datagridview.
This is where I am setting the row to edit: Private Sub ModifyRowToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ModifyRowToolStripMenuItem.Click If Not datagridview_TagAssignment.CurrentRow Is Nothing Then [Code] .....
I am always ending up on row(0) and never the row I right clicked on. Private Sub datagridview_TagAssignment_CellMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles datagridview_TagAssignment.CellMouseClick If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then datagridview_TagAssignment.Rows(e.RowIndex).Selected = True End If End Sub
This is my first time using the checkbox in a datagridview. I added the column at design time and it is false for readonly and frozen. But when I click on it at runtime nothing is happening. Do I have to check it through the event?
i need to know exactly when a checkbox is checked either by clicking or by spacebar.
I have looked at cellbeginedit, cellclick, cellcontentclick,cellendedit,cellformatting,cellleave,cellpainting,cellvalidating,cellvalidated,cellvaluechanged, and cellvalueneeded.
None of these inform me of when the checkbox value is changed. cellclick is almost the one, but it fires before the value is changed. cellvaluechanged doesnt fire until you leave the cell. the cell value changes and the cell is painted even if you dont leave the cell.
I have spent all day trying to get it right. I want to detect exactly when the checkbox value is changed so i can do some calculations and depending on the calculations, i may cancel the check mark.
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

i have a datagridview with three columns. i set the first column to visible=false, so the user can only see two columns.when the user presses the tab key in the first visible column -- column(1), i want to ignore column(2) so that the user only tabs through the rows in column(1)i can't get it to work. it will always tabs through the rows in column(2) even if i use the column name.
In my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.
