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";

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

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.

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

You mean, deleting this word doc by using Client-side script? then, the answer is NO. You should write the server-side code to delete that file.

Yeah. What Paddy Boyd said is right. Write "
File.Delete(filePath); " in Button Click. If the user click this button which is located on the page which is shown in the browser, this code will be executed and will delete the file.

Hi,
to do the same you must have rights to delete that file.
(Rights to client to delete file).

Then you can delete that file.
Its easy to delete the file from server.

Thanks,
Sun Rays

To get something you must have to try once.
