  generate statement dynamically

  Nov 11, 2003 01:13 AM|LINK

  Here is the problem: WebControl.TextBox aaaab, aaaac,aaaad,aaaae; aaaab.visible = true; aaaac.visible = true; aaaad.visible = true; aaaae.visible = true; ... and I need to run above batch a number of times, now, I want to build a function something like void setVisible(string str, bool val) { (str+"b").visible = val; (str+"c").visible = val; ... } does anybody know how to accomplish this? this soulds like trivil, to generate statement dymamically, but i do not know how to do it. thanks for your help. ^^

  ::this soulds like trivil, to generate statement dymamically It IS trivial to GENERATE statements dynamically. Just you dont try to do this. WHat you try to do is EXECUTE statementy dynamically. What for? Does it make any sense? I mean, I never stumbled over the need for this. How does it come you: * Have only the NAME of the textbox, but nothing else about it * Can not use an iterator over all controls and their subcontrols (recursive) to identify all WebControls, possibly filter the name? With the latter you could basically do something like this: void setVisible (COnstolrCollection Controls, string str, bool val) { foreach (Control c in Controls) { WebControl.Textbox box = c as WebControl.TextBox; if (box != null) { if (box.Name.StartsWith(str) { box.Visible=val; } } else { SetVisible (c.Controls, str, val); } } } Not the fastest way (tons of string comparisons). Makes possible seense to pre-compute the list once and then just iterate over it.

  Hi, Personally I would rather write a function that can be called to handle the group.

  private void setVisible( bool visible )
  {
    aaaab.Visible = visible;
    aaaac.Visible = visible;
    aaaad.Visible = visible;
    aaaae.Visible = visible;
  }

  It would be much more readable, and maintainable. If ever another control is included in the set it is a matter of adding it to the setVisible function and the rest is taken care of. Hope this helps

  ::Personally I would rather write a function that can be called to handle the group. He propably can not. THere are a ton of reasons for this, like the controls are dynamically added from a database :-) Stuff like a survey system would work like this.

  ::WebControl.TextBox aaaab, aaaac,aaaad,aaaae; I did consider what you are saying and agree, but the above piece of code seemed to imply statically defined controls. Sorry if my answer was misleading.
