Hello,
Is it that you want the image in panel1, which is the same as the image in the grid, to be full sized when it pops up?
If so, try to specify a width and height for the image in panel1.
<asp:ImageID="image"Width="200px"Height="440px"runat="server"ImageUrl='<%# Eval("img_s") %>'></asp:image>
Thanks,
Louis
Thank you for solution but still not work. Maybe I need different script...What you think? You have some solution?
Guys is possible click in button image from gridview and this open ModalPopupExtender for see the same image but more big, so different filed?
Please Help me!!
OK,
I think I have something for you. I used the gridview image example on MSDN :http://msdn2.microsoft.com/en-us/library/aa479350.aspx to make my grid.
Basically, I use javascript to add a click event to the row when the grid binds. You could do it on the image itself, its pretty straightforward.
When you click the row, I get the image path and put that path into the image inside the modal panel, where the image size is expanded, then I show the modal.

Oh mamma mia! I change:
<asp:GridViewID="GridView1"Runat="server"DataSource='<%# GetData() %>' ........
to
<asp:GridViewID="GridView1"Runat="server"DataSourceid="sqlsource1" ............ and all field but not worl the javascript
In original script everythin is ok, but when change for put database,don't work the error say:cells.3.children : is null or not object.
So I change in:
var sc = elem.cells[3].Rows[0].src; --> not work
var sc = elem.Rows[3].Cells[0].src; --> not work
and I delete allprotectedDataTable GetData() {........................} all delete, and
delete this line command: Page.DataBind();
But not work............Why?
Hello,
You need to do a few things if you attach a new Datasource to the grid.
Frist - find the new index of the column that holds the image path url. That column index is the new index of ele.Rows[X].Cells[columnindex].src;
Second, make sure you handle on row databound. If you post the schema of your resulting table, I can help.
Thanks,
Louis
