    doubkle click?

    Are you talking about Win form or Web form?

  3. It's pretty straightforward. Use ItemDataBind event to setup ondblclick
    client event for every data row click. Something like

    private void dgSelection_ItemDataBound(object sender,
    System.Web.UI.WebControls.DataGridItemEventArgs e)
    ListItemType itemType = e.Item.ItemType;
    if ((itemType == ListItemType.Pager) ||
    (itemType == ListItemType.Header) ||
    (itemType == ListItemType.Footer))
    e.Item.Attributes["ondblclick"] = "onRowDblClick(this)";

    Javascript function onRowDblClick will look like this:
    function onRowDblClick (row){
    call showModalDialog ("AnotherForm.aspx", row, "<features>");

    I'm actually using a mobile form for that respect,but I think it has the
    same fuctions as a win form.
    What I did (which I don't like at all) is that I passed the caller form to
    the child form's constructor(having the required fields defined as public in
    the caller form) ,,in the child form then I set the fields to the selected
    row's values.

    Can u suggest me a better way of doing that in windows forms?
    Thanks (I like the version too:))

    a text box?

    For win form, your approach of passing caller to child
    form via constructor is good. Or you can have a public
    write only property in child form to pass caller to it.

    For web form, you can save object to Session, then in new
    page retrieve the object from Session.

  11. It's not clear what exactly you are trying to achieve. Did you manage to
    read the row parameter in the child form?

    That's eaxctly what I am going to do,I mean I'd like to read the row
    paramtere in the child form and pass it to a textbox.
    ALI-R, Feb 15, 2005
  13. You should do it on client side with javascript, for example in <body
    onload...> event. The parameter is available as window.dialogArguments
    property. Once you get it, you can set the value of the textbox in the same

    but when I use the window.dialogArguments,it returns an "object".How can I
    get the value of that object in my javascript code?

    ALI-R, Feb 16, 2005
  15. it's a variant. it will be of the same type you've passed. in your case you
    will get the row.
