if you are using runat=server for any control then defin the tag like
in javascript method use like following
document.getElementById("whateverID").checked

If you use runat=server then the name will be changed better see in viewsource or/use
document.getElementById(CustomerInfo").Checked
or try this also
document.forms[0]["checkbox1"].checked

hi
it is not working
if possible give the code.plz
|
|
|
|
|
function codename() {
if(document.form[0][checkboxname].checked)
{
document.form[0][textname].disabled=false;
}
else
{
document.form[0][textname].disabled=true;
}
}
|
|
|
|
|
What exactly isnt' working? Are you getting an error?
|
|
|
|
|
If you use runat="server" you need to create javascript variables to hold the client side Id, which is represented by the ClientID property, and is not the Id you set on the server side.

Hi friends..plz go through this pseudo code
I Included Requirid Namespaces
Dataset ds;--------------------------------------1
//static Dataset ds;-----------------------------2
protected void page_load(parameters)
{
ds = function in Data acesss Layer which retrives records from database and returns dataset.
populatedatagrid();
}
void populatedatagrid()
{
if(mydropdownlist.selectedIndex=0)
datagrid1.datasource=ds;
else
{
datagrid1.Datasource= here I performed filtering action using Row Filter Property and selected Index Value
}
}
void mydropdownlist_selectedIndexchanged(parameters)
{
populatedatagrid();
}
I am designing a web page where by default all records will displayed.but by selecting from dropdownlist I can filter the records.Later I thought its not right to perform the fuctionalities of the page_load event at each postback(unnecessry making connection to the database)..so i used Page.Ispostback to avoid that..so first time it worked fine but when i selected from dropdwn list it throws an error "object reference not set to an instance of object"..
reason for above error i understood(because in page load event i am returning dataset which does not happened at page post back)..so one of my friend commented the line no-1 and uncommented the line no-2 in above code..thus made dataset static..and it works
What I am not understanding is why making the dataset static solved the task..though HTTP is static?Is making dataset ststic makes the records to be saved at server?

change the property of dropdownlist autopostback property to TRUE and try
|
|
|
|
|
Change dropdown property autopostback to TRUE
|
|
|
|
|
Please note that you have an option to modify your message.
And what the PostBack property is going to do with the Question?

Please don't use static unless you are sure that it will not create any side effect.
Consider the following program:
<code>static int i;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
i=i+1;
TextBox1.Text=i.ToString();
}
</code>
For each Button Click event, the value of "i" is incremented and displayed in the TextBox.
I have clicked the button 5 times and the text box shows 5 in it.
At this moment,when I opened another browse , copy - paste the same url
and I tried to click the button, it shows "6" in it.
So, I think that:
For the first request, an Object of the page is created and maintained in the server.
For subsequent request separate object is created for the page and is rendered to the Client,
and the static member is shared by all objects.

Arun Kumar.A

Thanks a lot Arun..u understood my question..and answered precisely..

Facing prob in retriving data .
When a item is selected from dropdown its index value goes in database , now when i want to retrive value in front end
i m not able to do tht as backend has int value and dropdown in list item contains string value
|
|
|
|
|
for dropdown there is a ValueField and TextField. hold the int value in ValueField and use dropdown.SelectedValue
hope this is what u asked?

You can convert that(string value) to Integer like this:
Convert.ToInt32("string value");

Hi!
I’m getting on buttonclick event following exception
Sys.Webforms.PageRequestManagerServerErrorException
When updatepanel is used in page.
Do you have any idea to solve this exception.
I tried a lot ,I got some ways to solve it Like
1) set EnablePartialRendering to false, but it is of no use bcoz whole page is getting refreshed ,to solve this issue only I’m using updatepanel.
<asp:scriptmanager id="ScriptManager1" runat="server" enablepartialrendering="false">
2)Set EnableEventVaildation=”false” not possible bcoz server side validation wont happen.
3)disabling cache in Role Manger in web.config
i put following code snippet in web.config
<rolemanager enabled="true" cacherolesincookie="false">
<providers>
<add
name="SQLOLEDB"
="" type="System.Web.Security.SqlRoleProvider" connectionstringname="ConnectionString" applicationname="MClosetURL">
but problem didnt get solved
4) I used javascript to catch the exception at client side in script tag in aspx page , In this case I’m not getting exception but nothing is happening after that ,server side click is not getting fired
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
if (args.get_error() != undefined)
{
var errorMessage;
if (args.get_response().get_statusCode() == '12031' || args.get_response().get_statusCode()=='12030' || args.get_response().get_statusCode() == '405')
{
args.set_errorHandled(true);
}
else
{
}
}
}

This block should be below the ScriptManager. Check whether you placed it in the right place.

good morning venkatesh!!
Thank you for replying me, after much longer wait finally i got reply from someone. Actually the code I have put in my page is working
bcoz sys.webforms.... exception is not coming but server side event is not getting fired afte button click, Postback is not happening at all.
I have used script manager in master page and written code in script in the page
in which that error is comming.
Even if i tried putting this script below script manager in master page but nothng different happened.
I Think in the if condition of code below
is it enough to have statement args.set_errorHandled(true);
or something more is needed.
Pls guide I want button click event at server side should get fired after exception is handled by the following code which is not happening in my page .
thanks a lot again!
have a very nice day!!
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
if (args.get_error() != undefined)
{
var errorMessage;
if (args.get_response().get_statusCode() == '12031' || args.get_response().get_statusCode()=='12030' || args.get_response().get_statusCode() == '405')
{
args.set_errorHandled(true);
}
else
{
}
}
}
