Hello,

I need to modify the properties of one HtmlInputImage from a cell in a bidimensional table.

To obtain the control HtmlInputImage I do:

HtmlInputImage image = new HtmlInputImage();
image = (HtmlInputImage)Table2.Rows[i].Cells[j].Controls[0];

Then, I modify the properties of the image.

How must I do to update the control in the same place of the table?

Thanks

Hi there,

I am not sure what you mean with your last question? With the code you have now, you'll be modifying the original image, inside the table. What exactly are you trying to do?

BTW, there is no need to set image to a new image. This will work as well:

HtmlInputImage image = (HtmlInputImage)Table2.Rows[i].Cells[j].Controls[0];

Cheers,

Imar

Everyone is unique, except for me.

I've created a table with n x n elements, in the way:

                imagen = Array.CreateInstance( typeof(HtmlInputImage), nFilas, nColumnas);
                Panel1.Height = nColumnas * 15 + 2;
                for (int j=0; j<nFilas; j++)
                {
                    HtmlTableRow r = new HtmlTableRow();
                    r.BgColor="Gainsboro";
                    r.Height = "15";
                    for (int i=0; i<nColumnas; i++)
                    {
                        HtmlTableCell c = new HtmlTableCell();
                        HtmlInputImage image = new HtmlInputImage();
                        image.Src = "images/tapada.jpg";
                        image.ServerClick += new ImageClickEventHandler(Imagen_ServerClick);
                        imagen.SetValue(image, j, i);
                        c.Controls.Add((HtmlInputImage)imagen.GetValue(j, i));
                        c.Height = "15";
                        r.Cells.Add(c);
                    }
                    Table2.Rows.Add(r);
                    Table2.Align = "Center";
                }
                Table2.Width = Convert.ToString(nColumnas*15);

The name of the image has to change if the user clicks on it. If the images changes, I don't need anymore the event handling. I want to change the image and deassing the handler.

            for (int i=0; i<nFilas; i++)
            {
                // TODO: recreación de las imágenes según estado de cada casilla
                for (int j=0; j<nColumnas; j++)
                {
                    if (tablero.casilla(i,j) != tablero_old.casilla(i,j))
                    {
                        HtmlInputImage image = new HtmlInputImage();
                        image = (HtmlInputImage)Table2.Rows[i].Cells[j].Controls[0];
                        //int Indice = Table2.Rows[i].Cells[j].Controls.IndexOf(image);
                        if (tablero.casilla(i,j) == TableroBuscaminas.EstadoCasilla.Vacia)
                        {
                            image.Src = "images/destapada.jpg";
                            image.ServerClick -= new ImageClickEventHandler(Imagen_ServerClick);
                        }
                    }
                }
            }

Doing like above, I change the image, but I need also to update it again in the table.

Sorry. I need nothing to refresh the image. All the problem was a bug in the logic.
Now, all is working right
