I have a DataGridView.
If I click over a column, it just selects a column like:
As you can see the Business Fax is selected, but my entire row is not, so in consequence, this.dgComm.SelectedRows.Count always throwd 0, but if I click on first column like:
it selects the full row and this.dgComm.SelectedRows.Count throws 1.
What I want to do is to prevent that zero. How can I select a full row if I just click in single column?
Regards.
There's a property on the DataGridView entitled SelectedMode, ensure this is set to FullRowSelect

I have a WinForms DataGrid (not DataGridView). When I manually select a row, the row indicator, shown in the first image below, shows on the selected rows. However, if I set the DataGrid's datasource after a save and programmatically select the second row using:
datagrid.Select(1), the second row gets the highlighted background color but the focus indicator is on the first row as shown in the second image below.
Is there a way to make the selected row get focus and have the indicator display for the row?
Since this is the old System.Windows.Forms.DataGrid, the Row selection method is slightly different than the DataGridView's.
You can select a Row, as you're doing, with the Select() method.
This doesn't change the Current Row. To make a Row the Current, you can use the CurrentRowIndex property.
Combined, these two move the selection and set the Current Row.
// Selects and highlights the Row at index 1
dataGrid.Select(1);
// Make the Row at index 1 the Current
dataGrid.CurrentRowIndex = 1;
Something similar in a DataGridView:
(One of the methods that can be used to achieve this result)
// Move the focus and selects the Row at index 1
dataGridView.Rows[1].Selected = true;
// Make the Row at index 1 the Current setting the CurrentCell property
dataGridView.CurrentCell = dgvTest.Rows[1].Cells[0];
Try this:
dataGridView1.FirstDisplayedScrollingRowIndex =
dataGridView1.Rows[dataGridView1.Rows.Count - 2].Index;
I'd like to show a listview in a C# application where every row represents a product so the property "view" is set on "detail". One column (the last one) should be a checkbox because it represents if the product is discountinued.
With the checkboxes property set to true, a checkbox appear in the first column so it doesn't work for my application.
How can add the checkbox to the last column? Thank you
The Checkboxes are always associated with the first Column. However you change re-order the display of the Columns.
All you need to do it go to the Columns designer and set the 1st colum's DisplayIndex to the last column's index.
Or do it in code:
listView1.Columns[0].DisplayIndex = listView1.Columns.Count - 1;
listView1.Invalidate();
Note the Invalidate which is necessary to enforce the display of the new layout..
At design time, I want to insert a row in a large TableLayoutPanel.
I want to insert an empty row, say at position 2, and have the contents of rows 2 through N move to rows 3 to N+1.
All I can find is the Add Row link, which adds a row at the end. Then I would have to manually move all the items in each cell down to the lower cell (which will take me 30 minutes) to free the row that I want to insert. Of course, I'd rather not have to do that.
Click the arrow, or in Properties sheet, select rows and click the ellipsis button.
You will see a dialog.
Select Rows from dropdown at top, and then position highlight and click insert.
You can right click the row where you want to add the new empty row, got Row and click Insert. This will insert a new row at the selected location.
I don't know if it's possible but I would like to have this column removed. I'm not sure what the name of the column is, it lets you select an entire row. It doesn't have any purpose in my program.
See the image below:
You should set RowHeadersVisible property to false.
I have a datagridview bound to a datasource, and in each row in the grid there is a category, product, and quantity. I want to filter the products in each row according to the selected category.
I'm using C# and DevExpress. How can I do this?
Please refer to the How to filter a second LookUp column based on a first LookUp column's value article which explains how to implement this feature.
Depending on how You want to filter you can set
gridView1.OptionsCustomization.AllowFilter = true;
This will display an additional filter row in your grid that will allow you to filter all columns by any text you want;
Or you can make sure that gridView1.OptionsCustomization.AllowFilter is set to true. Then there should be little icon on your column header (visible in right top corner when you move cursor over the column header) that will display filter after you click it.
