Hi
I have a Panel, which contains 'customer information', ie date of order etc. Input is aided by extenders, checkBox, date validation etc. All out of the box microsoft Ajax extenders. Works a treat. I have a close button - which when clicked, fires some javascript to remove the panel from the DOM, and then calls a webservice. The user doesn't care about the webservice, they're just pleased the panel has gone (quickly).
But....removing the panel does not remove the Script that the Ajax library injected into the page. So if they load up the Panel for the same customer, javascript errors are abound saying you can't add the same control twice - for each extender I try and add.
So...how can I, via javascript, remove the script that was added by the extender, or is there a safe way to remove the whole extender, including script, clientside. I really don't want a postback here.
Cheers

hello frndz.
i am using a dataset. and i want to retrivw value from that.
for that i am using
Textbox1.Text = dsAppData.Tables[0].Columns[0].ToString();
Textbox2..Text = dsAppData.Tables[0].Columns[1].ToString();
where "dsAppData" is the name of my dataset
... well through this i am getting the value.
but here the problem is.
if there are 20values neeed to be retrived from dataset.
the each time when i retrive the value i must use dataset.
so here i think it reduces the perfermance of the application as it hits
the database each time i populate the data from it.
so is ther any other way to retrive data from dataset only using once
means for the first time when we use the dataset we will keep all the requiered value
from it.
plz i need ur suggestion

DataSet is logical database. you can use it in connection less envirment. so it does not have any direct connection with database.
if you go through the details of ADO.NET , you will see there is connection oriented and connection less mode. and Dataset comes under the connection less mode.
So i think there should not be any performance issue if you use this .

Hi,
Guys anyone having idea about the Tools/ Third party Tools/ Mechanism to utilise already existing Visual Basic Forms into Asp.net Applicaiton.
Here I am explaining Completly:
Using RCW/Com Interop i am able to use the Class and methods. But if a class library contains Windows Forms as well, how can i utilise them.
Any suggestion regarding this will be a great help !
Thanks in Advance.

You would be much better (and it would probably be a lot easier), to simply re-write your forms in asp.net.
If your code separation has been done well, this shouldn't be a big problem.
|
|
|
|
|
Thanks for your suggestion !
That is the end solution ! Only Web Page creation is not a matter, Lots of events codes are associated with Win Form, so how to deals about that.
|
|
|
|
|
That's unfortunate, it would be handier for you if all that code was abstracted out, but anyway. You will need to rewrite these, if only for the reason that winforms is stateful and asp.net is stateless - i imagine that a lot of your event code will not work because of this.

How do i use an array of HtmlGenericControl. This is how i have tried to use.
HtmlGenericControl objUl = new HtmlGenericControl("ul");
HtmlGenericControl objLi = new HtmlGenericControl[5]("li");
objUl.ID = "nav";
objLi[0].InnerHtml = "First element";
objLi[1].InnerHtml = "Second Element";
objUl.Controls.Add(objLi[0]);
objUl.Controls.Add(objLi[1]);
mainDiv.Controls.Add(objUl);
where mainDiv is a server control. It is giving following error
Cannot apply indexing with [] to an expression of type 'System.Web.UI.HtmlControls.HtmlGenericControl'
Is it correct approach to build html body with an array of HtmlGenericControl? if yes then how do i use it . If no then whjat should be the approach....?please help

HtmlGenericControl[] objLi = {new HtmlGenericControl(),new HtmlGenericControl(),new HtmlGenericControl(), new HtmlGenericControl(), new HtmlGenericControl()}:
objLi[0].InnerHtml = "First element";
objLi[1].InnerHtml = "Second Element";

except that will fail with Null reference exception as you have not instantiated objLi[0] or objLi[1]
HtmlGenericControl[] objLi = new HtmlGenericControl[5];<br />
objLi[0] = new HtmlGenericControl();<br />
objLi[0].InnerHtml = "First element";<br />
objLi[1] = new HtmlGenericControl();<br />
objLi[1].InnerHtml = "Second Element";

if(document.getElementById('txtbox').value=="")

So what's the problem here ? Why don't you use validation control ?
|
|
|
|
|
yes here i used validation as below you see
if(document.getElementById('txtvalue').value=="")
{
alert('Entertext value');
document.getElementById('Asteristic').style.display="inline";
return false;
}
but it says "Object required".
How can i display the "*"(label control) only if the textbox is null?

I guess your textbox name is txtTickInfo. Check that

|
|
|
Your textbox id is txtTickInfo, not txtbox.

What sort of control are you expecting ? Usually a website just streams the file down as a download.
