Re: how to retrive data from dataset

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.

Hi All,

I am using CascadingDropDown on my web page and when I click on the save button I have to save all the data into database, which works fine.

But I want to set the values of CascadingDropDown to Select again.
Ex: I have 2 combo and when I say save then these combo's must be set to Select Country and other one to Select State.

Please help me with this.

Thanks in advance....

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";

Hi,

If the Textbox value is empty then, when i click "Ok" button an alert should display as "Please Enter the value for textbox" and simultaneously i have to display an "*"(Asteristic) only if the textbox is empty. Otherwise don't display.

Please help me..

if(document.getElementById('txtbox').value=="")
{
alert('Enter text value');
return false;
}
-------
<asp:textbox id="txtTickInfo" runat="server"></asp:textbox>

<asp:label id="Asteristic" runat="server" forecolor="Red" text="*" visible="false"></asp:label>

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

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

What is big there in implementing download functionality ? Provide a link to the file, and download will be managed by browser.
