in a databound scenario I have a database column value that is of type
varchar with 3 discrete text values.
Binding to this table column with autogenerated columns displays the text
values in a DataGridViewTex tBoxColumn column type.
I would like to display images as follows but I need to do so with the
DataGridViewIma geColumn column type. How can I do that switcheroo ? Can I
set autogenerate columns to false and somehow transform the text values into
a new column that will accommodate the image display? thank you. -greg
private Bitmap Valid_Image;
Valid_Image = new Bitmap("green_b all.ico");
private void dataGridView1_C ellFormatting(o bject sender,
System.Windows. Forms.DataGridV iewCellFormatti ngEventArgs e)
{
if (dataGridView1. Columns[e.ColumnIndex].Name.Equals("S tatus")) {
String stringValue = e.Value as string;
switch (stringValue)
{
case "NV":
e.Value = NV_NotValidated _Image //cell display does not
display image but rather 'System.Drawing .Bitmap'
break;
case "V":
e.Value = V_Valid_Image;
break; 2 8858
Hi Hazz,
Remove the column, Insert(0, a new imagecolumn, Rebind the data source to
a lookup that returns the image file. This is just like the example in the
documentation on dataGridViewCom boBoxColumn; but you are replacing a column
with an imageColumn rather that a comboboxColumn.
HTH

Working at the event level here was completely wrong. Creating the image
types prior to databinding was the solution.

Dear all,
I have a datagrid which bind to a dataset object
Datagrid autogenerate propertie is set to True.
I need to create the first column of my grid to be used as an hyperlink and

Hi,
I have been trying to see if I can do the following:
1. Create a DataGridView
2. Create 2 columns in the DataGridView (1 textbox and the other combobox)
3. Create a DataTable containing my data. (AutoGenerateColumns is true).
The data is 2 columns of System.String cell.
4. If I assign the DataTable to DataGridView.DataSource, I get 4 columns. 2

Hi,
I have a DataGridView control, and I am using it's datasource property
to assign a datatable to it at runtime.
The datatable has some columns in it that I don't want to be visible.
With the DataGrid control in .Net 1, each Column had a property that
allowed it to be bound to a column in a datatable, so I could define the
columns of the grid, and which columns they related to in its
datasource, and they were all that would display.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
