DataGridView - Add Separate Gradient To Each Row?
Apr 21, 2010
DataGridView, add unique gradient to each Row I like to add a gradient brush to each row of my datagridview. I like to change the gradient colors for each row independently depending of some cell values in the row. I know how to add a solid background color to each, cell, row, column etc. but I do not know how to add a gradient brush to each row individualy.
I need to fill the datagridview with values, the datagridview is disconnected from any database or other data source. After filling the datagridview, I want to step trough each row, find my key values, decide the gradient colors and then add the gradient to the row.I like to do something similar to what I now do with a background color:
For Each R As DataGridViewRow In DGV.Rows
Dim CS As New DataGridViewCellStyle
Select Case i
[code].....
I am using VB.NET and VS 2008 and 2010.

I have recently moved from developing in vb.NET 2008 to vb.NET 2010. There is a form in the application that uses an old Ascend Gradient Caption control to visually separate sections of the form. These controls are located on a tab control. The problem isthat the gradient captions seem to be unstable. They appear in odd locations on the tab pages at runtime, and I can't seem to select them in the designer. I can choose them from the combo box on the property page and edit the properties, but they stillbehave erratically. I understand that these are older controls and was wondering if anyone has had this problem and/or could recommend an alternative control

I have a datagridview (datagridview1) on my form which onload displays all the records from the bindingsource (bindingsource1) via an sql connection to a table in sql server called "article".
I also have a combobox on the same form which displays the name column from the same "customer" table -
Me.ComboBox1.DataSource = customerTable
Me.ComboBox1.DisplayMember = "custname"
Me.ComboBox1.ValueMember = "custid"
I would like to enable my combobox to filter the datagridview via itsSelectedIndexChanged event . So if custname "xxxone" is selected in the combobox then the datagrid shows only the results for custname "xxxone".
So far I have worked out how to enable the combobox to move to the position in the datagridview depending on which custnameis selected-
Me.myBindingSource.Position = Me.ComboBox1.SelectedIndex
But this method still shows the other titles,it doesnt filter them out, it just points to the selected custname. I cannot find how to filter the datagridview so ONLY the selected custname is shown.
I will be changing the field names, I have used custname and custid just to describe what I am trying to do.

I'm a bit puzzled here. I did a form containing a simple datagridview containing data from an MDB file. The connection was alltogether done by Visual Studios wizard so alot of stuff was created automatically. Then I databinded the textboxes to each column in the database and managed to update the database via my own command buttons such as "Update" with this code:
Me.MainTableBindingSource.EndEdit()
e.MainTableTableAdapter.Update(Me.DBDataSet.MainTable)
Me.DBDataSet.MainTable.AcceptChanges()

I want to be able to have a dozen or so text boxes be emptied into separate columns in a row of a datagridview. This way the text boxes can be cleared and have new values entered then save the new values as a second row in the datagridview. This is so my VB gui which which runs everything through an old cmd line program, can do batches instead of one run at a time.
The problem is I have absolutely no idea how datagridview works. I've tried searching google and only found some vague things and stuff about databases. I also tried the MSDN library and that was of no help either, couldn't find anything on simply adding stuff and if I had it'd probably be to complicated to be of use to me.

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

I am working in vb.net, visual studio 2010.
So i want to apply gradient to a square, a center to edges gradient. This is the code:
Public Class Form1
Private Sub PicSourcefrm(ByVal sender As System.Object, ByVal e As PaintEventArgs) Handles Me.Paint
Dim Graph As Graphics
[Code].....
NOTE: Picsource is just a PictureBox named that way. If I put "BrushSquare.SurroundColors = Color.Red" in a comment. The program works but the edges are white, not red like I want them to be.

I have this code for a gradient form(EXAMPLE 1). It works fine on its own.I tried putting it into an existing project of mine and I cannot get it to work. The project is quite large so I am no sure what the issue is. Is it due to the fact that I have an InitializeComponent() line in the my Sub New in Example 2? Note I have alot of code
EXAMPLE 1:
Public Class Form1
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint

I am creating a page that auto-creates a pdf file from data in the database. I have the entire pdf working with the exception of the pdf background. The customer wants a gradient which I will need to repeat, but how would I create this? the image is 1px in width 976 in height [Code]. I was hoping that declaring a longer width it would stretch the image across but this failed.

I am using Visual Basic.NET 2008. I was earlier a VB 6 developer. I found a (VB 6) code online which generates gradient colours on a form. It has a small sub (routine) which does the trick. If we pass red, green and blue values then form's backcolour changes and it appears like a gradient.Now that code is not working in VB.NET.i mean is there an easier way to generate gradient colours in VB.NET (2008)convert the code I have into .net specific so form's backcolour becomes gradient.I have attached a zip file which contains the code.

How can I change a form's backcolor to gradient one. The code (VB.Net) -
e.Graphics.FillRectangle(New Drawing.Drawing2D.LinearGradientBrush(New PointF(Me.Width, 0),
New PointF(Me.Width, Me.Height), Color.FromArgb(0, 58, 140),
Color.FromArgb(0, 215, 255)), New RectangleF(0, 0, Me.Width, Me.Height))
'fade from left to right
This code changes the form's background to a gradient one. It works fine. Now I want this to take place in an MDI form which will be a container for other forms. If I turn option IsContainer = False then it works but otherwise it does now. How can I change backcolor of MDI Form to a gradient one ?

in the painteventargs of the form, i've got something like this: [Code] i'm getting a very cool gradient effect from red to yellow, but why is that the case? shouldn't the 1x1 portion be totally red? and the remaining pixels be totally yellow?
i'm not trying to paint a 1x1 portion in my form, im trying to know why e.Graphics.DrawImage(bm, 0, 0, 100, 100) doesn't draw a 1x1 red portion on my form through the code provided above. my understanding is that 0,0 specifies the point to draw the image. bm specifies the image actually drawn, which is 1x1 px. and 100,100 specifies the allowed space for the graphics to draw, if this is correct, the first pixel should be red and the remaining 9999 pixels should be yellow but they aren't.

I've got all the code figured out to make a picture box appear with a gradient inside of it. My problem is that the gradient doesn't appear in the picture box when the form loads, paints, or when the picture box is painted. I can only make the gradient appear if i click the picture box after the form appears.

Dim xFormBottomColour As Color = Color.DarkOrchid

I have a form which I am adding a gradient to. However on this form I have aTableLayoutPanel (with controls) with the dock set to Fill. When it fills it covers up the form and the gradient on the form. Is it possible to make the TableLayout Panel and its controls colour clear or can you pass the same gradient color from the form to all the controls in the TableLAyout Panel (including the TableLAyoutPanel).

I am using a MDI form and child forms. Now I don't like the standard back colour of mdi form so I got code on the net which paints a gradient colour to the mdi. So far it is working okay.Now the problem is when I load a child form or close it or do a similar activity then it causes flicker in the mdi background. This gets pretty annoying at times and you see the background flicker.
