I'm trying to align datagridview columns at once to middlecenter. It works for the first column and does not for the others. I suspect it's a matter of the datasource property which is bind to a datatable which catches data from a SQL Server table. Below is my simple code and I thought that after this code runs I would have every column aligned to middlecenter:

how to change the Cell Alignment depend on the conditions. If cell value is text then cell alignment should be Left and If cell value is Integer then cell alignment should be Right.
I am going to change the Default Cell Style property then all cell alignments are changing.. But i want to see if cell value is Integer then the value starts from Right Side...
I am using vb.net 2005. I want one clarification for datagridview.I use the following property to set the alignment of header text:
DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomCenter

View 1 RepliesI have a datagridview to show the database data in order to let the user view the data. But i am thinking of adding a checkbox column to the datagridview and when the user selects on the checkbox in the datagridview on a particular row, he can actually delete that row when he checks the msgbox are you sure you want to delete this?
I am also not sure on how to provide the provision for user updating through the datagridview. If he can update through the datagrid view and press the save button, and the database is updated, it would be better.
Currently i wrote the code for the inserting of data already . But i am stuck at the deleting and updating of data through datagrid view. the below is my code for inserting of data

I have a DataGridView.DataSource set to a Collection of custom objects. The columns use read only properties from the custom object for display, this dialog is for display only. The properties all return String objects. I set the columns all but 2 of them to sortmode automatic (the ones that are not set is a button or a checkbox). Yet it does not sort. I have googled around and most people use sql or binding sources but I am using a trivial vb collection. Some say I should implement IComparable but isn't String already IComparable?
Per a request here are some code snippets.
This method defines the columns in detail from columns I designed in the designer.
The column names are called pSelected or pCustomer and corresponds with a property by the same name that the column definition ties to.

View 8 RepliesI used to have a single DataGridView (DGV) on a form. I formatted and populated this, then used DGV.Show to make it appear on my form. This worked fine.I upgraded my form, to included 2 DGVs. Within a sub I dim a new DGV, populate and format it as before then set this equal to whichever DGV on the form it's meant to be. For example:
Dim pDGV as new DataGridView

1) My problem is that, when I uncheck the checkbox in Cell 2, I want Cell 9 and Cell 6 to be empty.
2) When I uncheck the checkbox in Cell 2 and click any other Cell in the datagridview and check again checkbox in Cell 2 - it DELETES the data in Cell 9 & 6.
Now, when I check again the checkbox in Cell 2, Data is not populated in Cell 9 & 6 regardless how many times I try....

I have a datagridview with 4 columns (bound to a datasource).The following code ensures only numbers can be typed in the first column, all but numbers in the 2nd column, and only letters in the 3rd and 4th cooumn. It also converts the input in column 3 and 4 to capital letters.

The problem I have is that the user still has the possibility to place restricted characters in a column by pasting them in (with ctrl+v or right click-->paste), because the keypress doesn't notice the pasting.What should I do to make it impossible for the user to use restricted characters? In other words, how can i check the text the user wants to paste in a cell (cause that's the only other way to input data I can imagine)
Basically I try to get a DataGridView and a BindingSource working inside a class. I define them by:
Dim TempDGV3 As DataGridView = New DataGridView
Dim TestBinding As BindingSource = New BindingSource
When I manually add columns to the DataGridView, it works perfectly, but when I set it's DataSource to a bindingsource from a base class, it doesn't load data and keeps throwing 'object does not exist' errors. The bindingsource mentioned here did, however, work on other DataGridViews that are defined in the base class (and implemented in the form to which the base class belongs)
Same for the BindingSource(not the above mentioned, but the one I try to create inside the class in the beginning of this post). I try to use it in the following way:
TestBinding.DataSource = TempDGV3
TestBinding.Filter = filterString()
SourceDataGridView.DataSource = TestBinding
But the BindingSource keeps returning 'Nothing' for it's datasource and basically doesn't work. However, the SourceDataGridView mentioned here gets filled with 63 columns with "AllowUserToAddRows" and other properties when the columns names are asked.
So my question is: how do I get the BindingSource and the DataGridView to work in this class? I'm getting the feeling I'm missing out on something very obviously here. If that's not the case, I can report back with more code?
I have a datagridview that takes time when loading, and once loaded, is also very slow when using the scroll bar to see the other rows.[code]..
View 12 RepliesI have a datagridview control that where I need to color the rows based on a value in one of the cells in each row. I'm using the CellFormatting event like so: [code]This works fine when the grid loads and when I scroll it, etc. But when I click on the column headers to sort the grid, e.Row Index is always zero and all of the rows get the formatting of the first row..[code]For some reason, e.RowIndex is set correctly here but not on the other methods. The only thing you have to worry about here is it can be -1. But when I tried to use other methods, including PrePaint, I had to deal with it always coming up zero on a sort. If I exclude the zero case, like I excluded the negative one case about, then the first row is always white!!! I'm not sure why this works, but it does. It also produces no flicker beyond what I got using the CellFormatting event.
View 2 RepliesIt is a few years later and the same issue pops up! The enviroment is 50+ dynamically created DGVs that work properly except for having to format the data supplied as the DataSource to the DGVs Alignment appears to work but formatting does not. The datasources are 1 of 2 sources. 1) a datatable from the program 2) a SQL database. If you format the datatables everything works well. The additon of ValueType had no effectdoes not work

View 2 RepliesI am bringing in data to a richtextbox but when I bring it isn't aligned like i thought it would. Is there a property or something i need to enable to get this to work. Here is how I would have imagined it to work:-I figured this wouldn't display correctly.this was just an example, but was hoping to have the asterisks display even with the last asterisks on the first line and the slash on the last line.
/************************

* Some Text *
************************/
The text when i look at the .Text Property and click the magnifying glass shows it like i would imagine but within the control itself the alignment is all over the place and doesn't make much sense how it is doing it. If i bring the same text file into notepad it all looks fine and is also aligned correctly.what I need to enable to get this to work?
I should also mention that I thought maybe it had something to do with tabs, but when i view the .rtf property for many of the lines that should be aligned still are not even without tabs.

How is it posible to align each "Column", so that, no matter the size of each value, the columns line up perfectly under each other.

I have a PictureBox that is docked in the upper left corner of a form. It is contained inside of a SplitContainer, and the PictureBox is set to Fill the side of the panel that it resides:
SplitContainer:
___________________
| _________ >
| | | >
| | LogoBox | >
| |_________| >
|___________________>
I have the SizeMode set to Zoom so that the image will be resized to fit the bounds of the PictureBox. By default, the image is centered with this SizeMode. I am wondering if it is possible to force the image to be left-aligned instead of centered.
I've added a status bar to the form and have it set to "RightToLeft" True so that it adds my Label to the far right hand side.Now what I wanted to do was add a label that is left justified, but I can't figure this out by looking at the properties, so I'm assuming this has to be done through code somehow?I'm aiming for something along the lines of a browser's status bar layout.
