sir,
i have two tables and want to interchange values in eachother. How to implement state management in c#.
|
|
|
|
|
This question is very hard to answer.
1 - what sort of tables. In the database ?
2 - what do you mean by state management. Do you know what it means, or did you see it in a magazine ?
3 - what values do you want to swap and why ?
State management is build in, just use viewstate or the session. Perhaps if you can better explain what you need, we can give a more specific answer.

Code is below.
Problem is that when I delete 1st row, it gets deleted successfully.
When click happens, post back takes place. In page load, again resetting of dataset etc takes place. Now again dataset is populated with original values.
Please note that after deleting one row, I am not transferring the change back to connected data.
So how to achive it i.e. delete as many as rows in disconnected mode (without transferring any change to connected database).
IF I put all code of page load in (!Ispageback), it will not work because in deleting event, it will not find instance of ds etc.
More details:
Say 3 rows in dataset. I delete one. it is successful. post back takes place. In page load, again data set reinitialized, again filled up with 3 values (because after 1st deletion, we have not update the live data). So how to set the variables in such a way to achive it?
----------------------------------------------------------------
public partial class database : System.Web.UI.Page
{
OracleConnection oo;
String tt;
OracleDataAdapter adp;
DataSet ds ;
DataTable dt;
DataRow rw;
protected void Page_Load(object sender, EventArgs e)
{
oo = new OracleConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
tt = "select emp_id,emp_name from ado";
adp = new OracleDataAdapter(tt, oo);
ds = new DataSet();
adp.Fill(ds, "ado");
GridView1.DataSource = ds;
if (!IsPostBack)
{
GridView1.DataBind();
}
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
int pos = e.RowIndex;
ds.Tables[0].Rows[pos].Delete();
ds.AcceptChanges();
GridView1.DataBind();
}
}

Once your page has done it's work ( such as deleting a row ), redirect it to itself. That way, if you refresh, it will reload the page without regenerating the event.

I am trying to implement your idea but does not work.
Can u give an example or 1-2 liner snippet of code.
Again summarizing my requirement:
1. I should be able to delete the rows one by one in disconnected mode.
2. After deleting one row from disconnected, I am not making any chnages to live(connected) database.

Oh - I see. You want to delete lines from visibility, but NOT from the database AT ALL ? How bizarre.
I guess you need to transfer your data to viewstate on first read, and then manipulate it from there, without ever referencing your data source again.

You have to write a simple query for that, which will retreive data from two table based on join condition. Output of the query would be the source of GridView.

You should buy a basic book or two before attempting this task, you need to cover some basics, or you're going to keep hitting the same brick walls.

I create a webservice and when i build it , "Build Succeeded"
but when i run it it has a error in IE .what shoud i do?
The error in IE is :
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

Does it consumed properly by any client? 
I think there must be some problem with the WSDL. Check the WSDL generated with the web service, and find if there is something missing. Also check the WebService interface.

yesterday i ask you about the webservice and you guide me to this link:
//msdn.microsoft.com/en-us/library/8wbhsy70%28VS.80%29.aspx#Mtps_DropDownFilterText
I do steps but when i run .asmx it has error that i said in my main question.
additionally when i want to open my webservice it has some erorr:
configuring website with asp.net2 failed.you must manually configured this site for asp.net 2 in order for the site to run correctly.
if WSDL has some problem how can i solve it?

Is it possible to show us what you did to build web service. I think it shouldnt have any problems. 
|
|
|
|

I send my webservice and my website that use webservice to your email.
I run conver.asmx (it is class in my project)
I thank you that you answer me.

You realise that you don't 'run' webservices' as such, although it SHOULD show you an interface if you browse to it. What if you view the source ?

Im using AJAX to load the HTML from usercontrols through a webservice.
My webmethod returns a string(which is the resulting html from the ascx) and then in javascript i add it to the page. To test, in my usercontrol i have this:
<pre>
<script type="text/javascript">
function meep() {
alert("heeeeelllooooha");
}
</script>
<a href="#" onclick="meep();">Click here</a>
<pre>
Which in my mind should add a javascript function to the page. But when i click the "ClickHere" link it says meep is undefined(i know this thanks to the firefox webdeveloper toolbar)
Thanks

If you read about web tech you might come across, anything that implements IHttpHandler, can only handle Requests from the client. ASCX or rather UserControl is not inherited from IHttpHandler, so it cant be called directly from the client. You need to add the user control inside a page (which implements IHttpHandler) and then call the page from the client.
I guess you are using XMLHttpRequest object to make request. When you get the response, you need to place the responseText a div or any container of your wish.
Generally if you set innerHTML you are actually stripping out the <script> elements from the request. So you need to eval Scripts before you place the innerHTML. Rather than doing so, I would recommend to place all the javascript blocks into a javascript file and then from html you call the function.
I think this way your problem will be solved. If you find any more problem, just paste your client side code here to help you. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Sounds perfectly reasonable. I would prefer to eval them to keep everything in one file(without having to call external js). So how would i go about that? Im using normal asp ajax webmethods with a webservice. And yes im using innerHTML. So what do i need to do just before setting the innerHTML?
Also, if I did decide to have external js files then how would i include those? Because surely when i sent through the <script> tag to include it it would be stripped out too when setting innerHTML?
Thanks alot

Well,
Just use this :
function sethtml(div,content)
{
var search = content;
var script;
while( script = search.match(/(<script[^>]+javascript[^>]+>\s*(<!--)?)/i))
{
search = search.substr(search.indexOf(RegExp.$1) + RegExp.$1.length);
if (!(endscript = search.match(/((-->)?\s*<\/script>)/))) break;
block = search.substr(0, search.indexOf(RegExp.$1));
search = search.substring(block.length + RegExp.$1.length);
var oScript = document.createElement('script');
oScript.text = block;
document.appendChild(oScript);
}
var container = document.getElementById(div);
if(!!container)
{
while(container.firstChild)
container.removeChild(container.firstChild);
container.innerHTML = content;
}
}
Now once you receive the response, instead of directly setting the content to the innerHTML, pass it to this function:
say the id of the div is dvResponse, then
setHtml('dvResponse', ajaxResponse);
The function will find each script blocks using RegEx pattern and add them at the end of the page. If you want the script in head sectionn, just replace the line
document.appendChild(oScript); with document.getElementsByTagName("head").item(0).appendChild(oScript);

Yes.. you are right.. In that case you need to add the scripts on the original page where the container div is.

brilliant, works perfectly
One more question if you dont mind. At the moment if i add two of the same control they obviously have the same javascript functions. So when i do a function it will run the wrong one etc. Is it possible to encapsulate these controls like [if they were c#]they were two seperate classes with private methods, but still with access to my main classes(the javascript variables and functions on the asp.page that werent added by any contols) pubic methods.
If not, how would i do it? I messed around with dynamic functions and incrementing an int for each function name but thats plain messy.
Thanks

Thanks ..
Well.. If you are unsure that the same script may come twice to the page, I think you have to name each script block using ID.
use <script id="srpt">
and before doing appendChild(oScript) just do a call
var scrElem = document.getElementById("yourId");
if(!!scrElem)
document.appendChild(oScript);
Hope you can do it now. Just need to alter the script a bit.
Thanks again for appreciating.. Dont forget to click "Good Answer" if you like my solution.

Ok I know what you mean but I didnt explain properly.
Lets say i load the same control twice and each one outputs the same javascript:
function doSomething()
{
//something
}
function doSomething()
{
//something
}
And then in each control if i have <a onclick="doSomething">click</a> it wont neceserily run the function that was generated by it.
This is why i was asking about encapsulation, so if each control could only have access to its doSomething function it would always call the right one.
I dont really want to got the route of dynamically making doSomething1(), doSomething2() etc for each control thats added. That seems sily.
