Re: Problem with OnClientClick() & OnClick()

8-Dec-09 7:46

<asp:Button ID="btnOK" runat="server" 
OnClientClick="javascript:return checkMinHour('txtHourFr', 'txtMinuteFr', 'txtHourTo', 'txtMinuteTo');"            Text="OK" Width="78px" onclick="btnOK_Click" >

Just if you return false to the Onclick of the client side, it will not call the serverside and hence the postback will be removed.
Also what is the meaning of checkMinHour(txtHourFr, txtMinuteFr, txtHourTo, txtMinuteTo)... ?? If the arguments are names of some other controls, you must use quotation while passing them. Now the function will look like :

function checkMinHour(txtHourFr, txtMinuteFr, txtHourTo, txtMinuteTo){

  .... ...
  .... ... 
  if(Data is valid)
   return true;
  else 
   return false;
}

Cheers...

User Controls

Hi-

I want to create a container user control which will have two place holders (one on left and one of right). Developers should be able to put this container control on their page and set properties to decide which user controls they want to load (dynamically) in those left and right place holders in the container control. For example, i want to create a container control C1.
Developers can put this C1 on their page like
<C1:C1 ID="ucC1" runat="server" uc1="2L" uc2="1R" uc3="1L">

So basically ucC1 is the container control. uc1 and uc2 and uc3 are other user controls that developers need in those place holders (left and right) inside the container control. And "2L", "1R" and "1L" decide the position of the control. for example "1L" means load that one first in the left place holder, 1R means load that one first in the right place holder, 2L means load that as second control in the left place holder, etc....

Now I was wondering, if there is any better or more efficient way to do this whole thing, or atleast a better way to do this "2L" kinda ordering?? Also, i am using the properties of container control to load other user controls dynamically, is this the best way or there's a better way to do this? Any help would be much appreciated! thanks

A wild guess

You can have a user control which exposes a Dictionary property. There, key can be a placeholder ID. And the value will be control's name. Then, in the set block of the property, you can add the mentioned user control in the container control.

Or, you can have a property each for each PlaceHolder and in its set block, load the mentioned control.

Retrieve value from TextBox inside a GridView

8-Dec-09 8:40

I think you are not looking for User Control... Rather you are asking for Custom Control.

There are two ways to do this, either you create the whole control yourself by deriving from INamingContainer interface, which requires lots of efforts or inherit from an existing control.

I think your requirement needs a completely new control to be created.

Just create a class, derive from INamingContainer, place ParseChildren attribute to all the template children etc.
This might come handy for you :

I hope you are now in right path.

Navigate to the row containing TextBox.

then, get the string value like:

string str = ((TextBox)Row.FindControl("txtName")).Text;

how to launch an application in the client system?

8-Dec-09 5:12

Use RowDataBound event of Gridview to find the context item.

protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {

    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      TextBox tb = e.Row..FindControl("textboxname") as TextBox;
    }

  }

Why do you want to launch an application on the client machine from the server? This can be done using client scripting, but has very high security risk and will not work if javascript/activex is disabled.

Hi Dinesh,

Thanks for ur reply. How can it be done?

Dinesh Mani8-Dec-09 0:38

I don't exactly remember how to do it, but you need to create activeXobject for the client machine's shell and use the run command on the object to launch the intended application. This would work only on intranet applications where the browser security level allows the browser to access the client machines' shell.

I think this is the code, but not sure, please test and modify -

w = new ActiveXObject("WScript.Shell");
w.run('notepad.exe');

Re: how to launch an application in the client system?

8-Dec-09 2:44

But let me remind you..

Shell commands are only available to IE... Thumbs Down | :thumbsdown:

and also if it has given previledge.

It will not work in any other browser..

So I recommend you to use a custom popup div in your page to show whatever you want to show, rather than opening notepad.

Also let me know if your have some specific requirement around this .. Rose | [Rose]

one more clarification,, how about using this?

System.Diagnostics.Process.Start("Notepad.exe")

This runs on the server and starts notepad on the server. This again has high security risks!
