Well my friend, the process you are using is actually creates one thread in the server side. You need the timer to work in the client side.
In disconnected env (Like Web) whenever a Response is transferred to the client, anything in the server regarding that request disposes. Whenever we call the server again, it will actually create another Response altogether.
Use javacript SetTimeOut/ SetInterval / ClearTimeout to deal with this.
You call like this :
function UpdateStopWatch(){
...
...
}
body onload="javascript:SetInterval('UpdateStopWatch', 1000);"

Hi all,
Please look at this following code of mine
<asp:Button ID="btnOK" runat="server"
OnClientClick="javascript:checkMinHour(txtHourFr, txtMinuteFr, txtHourTo, txtMinuteTo)" Text="OK" Width="78px" onclick="btnOK_Click" />
You can see 2 events OnClientClick() & OnClick(). All I want to do are:
OnClientClick(): is used to run a javascript which will check well-form attributes of some textboxes before executing function btnOK_Click ().
OnClick(): where I call function btnOK_Click().
What I expect next is nothing happens until users enter valid value to make well-form attribues.
The problem is: In the case my fom is not well-form, after running the javascript, an alert box appears. I then click button OK of it and btnOK_Click() runs continuosly. As a consquence, C# throws a page to inform "The input string was not invalid".
Have you got any suggestion for me?
Thank kiu so much!

Add return false; in your javascript method when you don't want server side code to run.

<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...

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

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.

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;
|
|
|
|
|
TextBox txt2 = new TextBox();
txt2 = (TextBox)GridViewName.Rows[2].FindControl("textboxname");
string a = txt2.Text;
not working
|

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;
}
}

Hi All,
how to launch an application [say notepad] installed in the client system on button click,..using asp.net?
please respond soon.
Thanks
|
|
|
|
|
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?
|
|
|
|
|
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');

Ok, thanks dude. i will try with this info.
|
|
|
|
|
But let me remind you..
Shell commands are only available to IE...  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 ..
|
|
|
|
|
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!
