is there an easy way to make the size of a datagridview expand dynamically (like say it is not long enough to display all the data it will grow in width), or do i have to implement this functionality manually?

I have 2 datagridviews on different tabs of a tabcontrol.The user can input names into datagridview1 column1.I want these names to automatically appear in datagridview2 column1, in such a way that when rows in datagridview1 are added and removed the same rows are added and removed in datagridview2.I also want the column sort function to effect datagridview2.
View 3 RepliesI'm using the follow code to grab values when a row is selected on my datagridview:
Me.DataGridView1.CurrentRow.Cells(0).Value
in this case for the first column. I am doing this for several columns. What I would like to do is switch to specifying the columns by name so the code won't have to be changed if columns are moved around. I have tried several things that didn't work. Can anyone supply me with the code to retrieve the value of a column on a selected row by the name of the column?
I have a simple DataGridView that I fill in with data from a SQL server source. The query is fairly simple and after the grid gets populated I manually add several new columns and then iterate through each row and fill in the columns with appropriate data. all that works well. but now when i click on a column header to arrange the data the data in the columns that were manually added disappears. is that suppose

View 2 RepliesI am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.
I have formated a column : "N2" but when it is : 1,2 or 1,3 or 2,3 .... then it OK BUT IF IT IS 0,1 OR 0,2 OR 0,.... THEN MY PROGRAM DETERMINE IT IS LETTER BEHIND ZERO , NAMELY THEY ARE 1 OR 2 OR 3.... I want it should be exactly 0,1 or 0,2...

View 2 Replies(All of this is in a datagridview) i would like to know if it would be possible to say, take Columns 1 and Column 2 and multiply the value of each row and post it to a Column 3 with each row in Column 3 reflecting the multiplied values of the previous 2 columns..

View 18 RepliesI�m migrating a project from VB6 to VB.NET 2010 Express. Im replacing msflex grid with datagridview. But i�m not quite familiar with it. Im not using datasource. This will be done (far) latter.
So far i�m filling datagridview by code reading a recordset from mdb. Works fine.
The problem is that, I have defined the columns at visual studio designer mode, without using any code. When I open my mdi child form for the first time it works. But If I close this form and open it again a error occurs because it loses the defined columns.
how to preserve columns defined at design after close de form?
My MS-Access database contains 30 "table" files with identical formats (e.g. Composer, Arranger,Lyricist, etc.) and I use a common VB.NET form and DataGridView for displaying and editing any one of the 30 tables. When a user makes a menu choice, the menu program puts the file name and its first field into two global variables and then shows a form that contains an unbound DataGridView. This other form then loads a dataset from the appropriate database table and programatically binds the DataGridView to the DataSet. (I clear the dataset before filling it.)
All goes well and three DataGridView columns are displayed for the first time. However on subsequent operations, the DataGridView retains the columns that were previously generated along with their column headings (but no data) and I get six DataGridView columns. On the third operation I get nine DataGridView columns.
I have unsuccessfully tried to obtain a count of the number of DataGridView columns so that I can remove them from the DataGridView but it always gives me a column count of zero.How can I accomplish the simple task of removing all columns from the DataGridView?

View 3 RepliesI have a program where i let the user dynamically add DataGridViews to the interface, those are also added to a list for easy management. All of the DataGridViews have their own datasources. I am using a Databinding source to get different DataGridViewTextBoxColumns to add.
The problem is the following: When the user adds the first table the following code runs:
dataGridList(dataGridList.Count -1).Clear()
dataGridList(dataGridList.Count -1).Add(NameDataGridViewTextBoxColumn)
No problem there and the right data is displayed, but when the user adds the second table i get an exception thrown:
"Provided column already belongs to the datagrid view"
I think this is strange since i access different DataGridView's right?
The point of all of this is to be able to view different columns in all the DataGridViews depending on the users choices.
Is there a way to add columns in a datatable to the intellisense of the datatable? Is there a way to display the columns of a datatable in a datagridview?

View 1 RepliesI'd like to copy some rows of data from a data-bound datagridview to a different datagridview.I thought adding a row would just be like this: [code]The trouble is that, instead of copying all the data from the row and putting it in the correct cells in the other datagridview, it seems to be taking the whole row object and putting it in the first cell, so the first cell contains this: [code]And the other rows are empty. How do I make rows copy properly?
View 3 RepliesRecently I was working on a project that included several DataGridView objects. With one, I dynamically create columns based on the types of data being displayed. I established a baseline size (so each column would initially display the same width), and a minimum size. AutoSizeMode was set to None. I knew that I wanted the new column to be resizable by the user, so I put in code to that effect:
Resizable = True
When I tested the code, the columns were not resizable. I traced the code, looking for anything that would reset the property Resizable to False. Nothing. I commented out the line with the
Resizable = True command;
The columns were resizable after this. At this point, I remembered that Resizable is defaulted to true. But I still did not understand why the columns were not resizable after setting the property to True.
I did some experiments. If you create a new DatagridViewTextBoxColumn, add it to the
DatagridView, and then set the Resizable property to True, the result (via Watch) is False {2}. If you do the same, but set the Resizable property to False, the result is True {1}.
This is disturbing (and confusing) on at least two levels. The fact that the exact opposite boolean value is passed in. The fact that {2} is False. It was always my understanding that VB treated
{0} as False, and
Any other value as True.
Is it possible to remove from a datagrid view very first "column" i.e. the row selector and also to remove the ability to reorder the columns ?
View 3 RepliesMy requirement is as follows, I am calling a procedure and I'm populating a DataTable. Assume that the procedure is returning emp_id, emp_name, designation and status. When I use DataGridView1.DataSource = <Name of the DataTable>, I get all the columns populated into the DataGridView. How can I display only selected columns in the DataGridView. For e.g, I want to show only emp_id and emp_name.Similarly, as to how I can increase the width of the columns of the DataGridView by writing code.
View 3 RepliesI have a datagridview that is bound to an access database. The first column is a checkbox, the second is first name, the third is last name, the fourth is start time, and the fifth is end time. Is there a simple way that can either be explained to me, or demonstrated with some example code to have the data copied from the first name, last name, start time, end time when the checkbox is checked in the corresponding row? (there are other columns in the datagridview, but i only want the first four cells copied that are in the same row as the checkbox to be transferred to the second datagridview. This would also have to be able to work for each checkbox in each row)
