I want to add DomainUpDown control inside a DataGridView as a separate column. Each time a new row is added, I want that DomainUpDown control also be added. I also want to know when the user click the DomainUp or DomainDown button in DomainUpDown control for each row. Is it possible or not? I am using language vb.net/C#. I want to do this in winform not in ASP. Any help or suggestion please!!!
All you need to do/know is how to add an unbound column to an already data bound DataGridView, because from your description you are trying to add a column to a grid which already contains other data bound columns. In fact it would be easier if you had such column in the DataTable, also because with unbound columns you need to make a slightly bigger effort to populate and save the data from/to somewhere.
anyway it should be possible, MSDN explains it here: How to: Add an Unbound Column to a Data-Bound Windows Forms DataGridView Control

I need to create an expander in my datagridview that adds additional info about that row to the datagridview when selected, and hides the same when collapsed.
This is possible by creating RowDetails templates in WPF, but can I do something similar in winforms datagridview? A workaround I'd thought of was dynamically adding objects to the datagridview on expand/collapse, but it won't work in this case because the number, type, arrangement of columns is very different for the details rows than the data rows.
Can RowTemplate possibly help? All examples I've seen thus far use rowtemplate only to fix height, width etc of rows in a datagridview and nothing else.
You can use ToolTip for selected row if you want to show additional data info.
I want to add a new row to a datagridview such that when a user clicks on new button , a new is is generated with few textboxes and combo boxes and after filling up all the details he save the info by clicking on save button.
EDIT
I want to do it like it is seen in gridview(Template Fields) in asp.net
I am looking for same kind of functionality.
Since I'm not sure exactly how you want to achieve this.. I would have a hidden panel with your text boxes, ...etc, show the panel when the new button is clicked. After all information is entered into the fields, click the save button. Assuming that you will be inserting this information into a table, after the row is inserted, call the stored procedure to get the desired records from the table being displayed in the grid.
Assuming your _dataGridView.Columns collection is not null and contains a template of the rows you wish to add, it is as simple as something like this:
foreach(var item in _collection)
{
_dataGridView.Rows.Add(item.Foo, item.Bar);
}
In order for this to work, you will have had to design your Columns collection in the VisualStudio designer or programatically add DataGridViewTextBoxColumn objects to the Columns collection.
In the example above, I added two DataGridViewTextBoxColumn objects to the _dataGridView.Columns collection and then populated the datagrid from a List of my object that contained a 'Foo' and a 'Bar'.
EDIT
Have you checked out the DataGridView FAQ? The information about using the DataGridView in unbound mode may help you.
HTH
I have been given a mockup that I do not know is possible to code in ASP.NET without being a real html and javascript wizard.
I want a GridView that when a row is selected, the selected row expands and below the selected row a panel of additional information is shown, which would also include another small GridView. The idea is this would all be in-line. So if the user selected row 4, then the additional information would appear below row 4 and then after the additional information the parent GridView would continue with row 5.
Ultimately I would want to do a multi-select type of set up, but first I need to figure out if this is even possible. Also, the solution must be 508 Compliant
The one solution I considered was using only one "column". Then I would put all my fields in the ItemTemplate, and my detail panel content in the EditItemTemplate and instead of selecting the row, set it to edit mode. The problem with this solution is I lose the functionality of multiple columns if I throw everything in one huge ItemTemplate.
Any and all suggestions or ideas are appreciated.
What you're describing would be best fulfilled with a ListView control. It takes a little more templating work to set up than a grid view, but you have much more control over it and you can emulate the look of a GridView. You would set your Selected Item template to contain another ListView (or GridView) thats bound to your detailed data.
I've done this using a gridview inside a ListView and using ajaxcontroltoolkit collapsible panel
Your parent list would be a listview that would have 2 table rows for each item, on the first row your parent column, on the second row use colspan and add a gridview wrapped on a collapsible panel
Howdy, using vs2008 winforms.
I want to be able to use a slightly customised datagridview but cant think of a way to do it.
i have
1. a sqldataadaptor fill a dataset
2. a binding source bound to the dataset
3 a datagridview with the bindingsource set as the datasource.
I want the binding to allow sync between the dataset and datagridview, so i can edit data and then update to database with sqldataadaptor. update.
I want to show some custom columns that are calculated results.
And i want to show a final bottom row that is totals of all the columns in the DVG.
My problem is once the DGV is bound i cant add a custom column or row, it wont let me.
I know i could add it directly to the dataset that is the underlying datasource but then by changing the structure of the dataset i cant update to a database once edits have taken place.
or can i ???
Can someone tell me how i can add my custom columns and a final total row to a bound DGV.
Also while im here, if i click on the top of a column to sort on it, in a bound DGV, will it also re-sort the underlying dataset, so i i edit things will still stay synced ?
thanks in advance for any help
Yes, you can.
The adapter does not care about structure. It only cares about column names used in the Select/Insert/Update/Delete commands. You can add custom columns, expression columns, columns for subtotals, columns for totals, or whatever you need. Even change the order of the columns. I do advise adding a sort column, so you can keep the custom rows in the proper place when you or the user sorts.
You can do the same thing for custom rows. When you update through the adapter, you handle the RowUpdating event and set the SqlRowUpdatingEventArgs.Status to SkipCurrentRow for these custom rows. I strongly advise creating a row type column so you know which rows to skip when updating. (You can also use the sort column's value as a key to skip rows.)
There are a couple of articles on MSDN or KB that illustrate how to add total rows.
"How to sum the fields in a Windows Forms DataGrid control and then display the calculated totals in a footer by using Visual Basic .NET" at http://support.microsoft.com/kb/836672.
In my experience, manipulate the data table first before binding. Do what you need to do in order to support the grid and the grid's interface. It is okay to manipulate the data, add/change/remove columns and rows, then rebind when needed.
To be able to add additional unbound columns to your DataGridView you could also set its AutoGenerateColumns property to false and then add custom columns with the following method:
dataGridView->Columns->Add(...)
To calculate the contents of the unbound columns you can handle the CellValueNeeded and CellValuePushed events but you must set the DataGridView into 'virtual mode' by setting the VirtualMode property to true in order for the eventhandlers to be invoked.
Hope this helps a little....
I have a DataGridView in a C# WinForms app that is DataBound at runtime (through Form_Load) to a custom Object.
In the design view of the DataGridView I have no columns set up.
When the Form loads the the columns are automatically created based on the data in the Custom object that it is DataBound to.
My question is how can I control the the Columns that are automatically created.
For example if I want one of the columns to be a DataGridViewLinkColumn instead of the DataGridViewTextBoxColumn that is automatically created?
The default columns are based on the data-type. I haven't checked, but for a link you could try exposing the data as Uri, but that might be hopeful. Really, if you want a specific type of column - add the columns through code and set DataGridView.AutoGenerateColumns to false.
As Andrew implies; normally something like reflection is used to generate the columns, and you'll get a column for every (browsable + public + readable) property. There is a layer of abstraction on top of this if you need, but this won't help with adding a hyperlink column.
You can pre-create your columns in the designer. If the name of the column matches the name of the property the column will end up bound to, the databinding will take care of the DGV population for you as before.
