my first datagrid custom column - feedback appreciated!

i have just developed my first datagrid custom column. it is very
simple. i know that each cell will only display a char value of 'T'
or 'F'. so if the cell value is 'T' i am displaying a ticked checkbox
image and if it is 'F' i am displaying a blank checkbox image.

it seems to be working ok but as this is my first attempt I am posting
my code as I do not know if I have coded it the best way. many thanks
for any feedback.

public class CheckboxColumn : BoundColumn
{
public CheckboxColumn( ): base()
{
}

public override void InitializeCell( TableCell cell, int
columnIndex, ListItemType itemType)
{
base.Initialize Cell(cell, columnIndex, itemType);
if (itemType == ListItemType.It em || itemType ==
ListItemType.Al ternatingItem)
cell.DataBindin g += new
EventHandler(On DataBinding);
}

private void OnDataBinding(o bject sender, EventArgs e)
{
HtmlImage hi = new HtmlImage();
if (((TableCell) sender).Text ==
"T")
hi.Src = "../images/checkbox_ticked .gif";
else
hi.Src = "../images/checkbox_blank. gif";
((TableCell)
sender).Control s.Add(hi);
}
}
[/code]

Hi, I have a datagrid that supports bi-directional sorting - i would like an icon (like an up or down arrow depending on the sort order) to be displayed in the datagrid column headers which changes dynamically when the column is sorted. Any ideas on how to implement this? If I have to create a Custom clumn for this (which derives from BoundColumn class), how do I proceed with this - how do I make a column that has a text and image?

Hi, In C# i) Is there anyway to input value on particular cell in datagrid in the coding? ii) How do I save the contents of the datagrid back to database? iii) I've made a custom datagrid myself, with button on column. However, what I really want is actually a textbox with button in one column. Is there any example regarding that?

I am creating a custom datagrid based, in part, from someone else's code. The author declared a derived datagrid class in a windows form, then declared a derived ColumnStyle class, in the same form, that accepted his custom grid type as an argument. For example: public class HisCustomGrid : DataGrid { public HisCustomGrid() { } } public class HisColumnStyle : DataGridTextBox { public HisColumnStyle(int anyint, HisCustomGrid grid) { } }...

I've been bothered for some time about my DataGrid not populating my rows very quickly. I have about 10K rows loading into the grid. I create a datatable dt with 2 columns, an ID and a display. The ID is a member of the keys array. I then create a DataView dv over the table, and sort it by Display and ID column (in case of duplicate Display). I then set my DataGrid.DataSource = dv; I then load the datatable with my rows, and this is...

Hi all, Have a datagrid that displays the price column of a table. Went to the Datagrid's Property builder and set the 'Data Formatting expression' for the PRICE column to {0:c}, so that the dollar sign, the comma, and the decimal are included (i.e. $44,644.48) Managed to update the price column of the datagrid back to the database, as long as, the user doesn't delete the dollar sign (in the 0 position).

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
