VS 2008 DataGridView Cell With MultiLine And Colors?
Feb 11, 2010
I have a big datagridview that has a list of items, that have several states, every state has a date. My dgv will look like this:
----- Date1 | Date2 | Date3 ...
It1 |
It2 |
It3 |
The same item can have multiple states in the same date, for example: The item1 enters the factory in the date1, and leaves the factory in the same date1, what i need it's that the intersection cell, have one line with the background in green with an F (means that the item enters in the factory), and in the same cell, but in another line (multiline) in the same cell i need another F but this time with the background red (means that item leaves the factory).
The usuals columns doesn't allow me to do this, i created a simple code to use a image column and then draw a image that does what i want, but i don't like the final results and it's a little slow, and when i select the full row, i don't have the usual selected cell visual effect in this columns... I was thinking to create a datagridview column with a different type (inherited) but i don't know what column to use as base column for my column, image column and then paint the content of another control in the cell or another type?

I have a MySQL database which acts as a source for a datagridview, is there anyway I can set colors to the rows based on values in a cell? So that if the value in a row in the field "Priority" is "yes" then the row is red?

I am using vb2008 and MsAccess2007.
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Dim SearchJob As String = TextBox1.Text
ds.Tables("MyTable").DefaultView.RowFilter = "ProductID =" & SearchJob
End Sub
By using the code above, I can search relevant ProductID details in DGV when I type the ProductID O want to locate. My question is, is it possible to perform multiple search using multiline textbox? That's all the result from the multiline textbox will be searched and showed in the DGV. If this method is possible, what code should i use? or rather, should be using any SQL Statement?

I've a datagridview with a multiline textboxcolum, if the cell content is small (one line) the scroll works fine and I can see the content of all rows. But, if a row cell content is very large (ten lines), only is visible the top of the cell and if I try scroll down, the scroll goes to the next row without can see the rest of the cell text, even using the arrows for move inside the cell, the bottom is not visible.I was searching in the web and the only solution is use panel and put inside the datagridview. It looks me a fix more than a solution.

I am working on a page where I need to highlight different events in a day with different colors in a ASP.NET Calendar Cell. The events are store in a database with a start date column.
For example, if we have two different events for today, the cell should display half green and half red color. If there are three events for today, it would 1/3 green, 1/3 red, 1/3 blue in the cell for today.
In addition, currently I use tooltip in jquery to hover a cell, it would display a tooltip above the cell. How to handle this when we have different events in one cell?

I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

I'm making a data entry form using a datagridview and I want to control which cells in a row are visible. For example, I only want the first cell in a new row to be visible until I validate what was entered - then I'll either fill in the other cells with data or ask for user input.

I am working on a vb6 to vb.net migration project using vs 3.5. I have a datagridview.in a particular cell of this grid, user has to enter only numeric data. but after user enter data, itshould become concainated with a $ symbol (eg: if user enter 34, the cell value should become $34). And if he/she presses the hyphen ("-") in the key board, the data (ie. $34) should become -$34 and if again presses the hyphen button in key board, the data should become $34.

I have a bound DataGridView where the user should enter an item number in one cell, the name of this item will be displayed in the next cell, and depending upon variables of this item number, the focus should be set to the correct cell on the same row.
My problem is that I can not seem to get the focus to the correct cell.
My code so far. I am having problems with the marked line:

I'm trying to format a column of numbers is a datagridview and I'm having some problems. This is the code I'm using: dgv.Columns(5).DefaultCellStyle.Format = "n2" If the number I put in the cell is 100.50, it shows up as 100.00. If I try to edit it back to 100.50, I get a "value was either too large or too small for an Int32" error. The cell also is accepting Char data. I want to format the column so it only accepts numbers in a '#####.##' format.

clearing cell contents within a DataGridView?I have a column with a list of names and would like to be able to make the whole column blank.I can currently achieve this (not the greatest) by clicking on individual cells and doing this ..
DataGridView1.CurrentCell.Value = " "
But rather than doing this I would like to be able to do every cell in the column, all at once. I'll put the code behind a button, so it can all be achieved by a single click.

Have this code so that when a checkbox in a column of my datagridview is checked, then the corresponding cell in column 2 (of the same row the check box is in) will turn blue with font color white.
[code]...
I'd also like to add a line so that as well as the cell going blue, the bottom border of the cell disappears, so cellborderstyle = none.

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

My program parses chat room text. In the room there are smileys that get displayed. What I'm trying to do is parse out the image URL, download the image and put the smiley in the correct spot between the text of the message.I can do the parsing and downloading of the image into the datagridview but this only works of the column is set as an image column. Obviously due to the nature of the program I need to be able to put both text and images into the same cell. How can I do this?

Well, the title pretty much says it all. I have a user control that is a a collection of six label controls. three are used as visual color indicators, and the other three are used as the corresponding value for each color indicator. (It's sort of like a legend key on a chart or map.) I have created a custom class to store the three values, and the associated methods to interact with the values. (I can probably use a structure instead of a class, but right now, I don't want to discuss that.) My problem, is that I want to show my user control inside a cell of a DataGridView. I've looked at the examples that create a MaskedTextBox DataGridViewCell, but I can't seem to get it to work. Here is what I have:

I have a DGV where I'm setting the backcolor of certain cells to light gray. But I need to be able to restore the backcolor to what it was before I changed it to gray. I could just set it to transparent, but the problem with that is that I use an alternating row color of alice blue for the DGV & setting a cell in a blue row to transparent makes it white. So, in summary, I need to be able to restore white rows to white & blue rows to blue. Any ideas? I thought about checking the backcolor of another column in the row & then using that to reset the cell, but that seems kind of a hack.
