foreach (GridViewRow rw in this.grdEmpSearch.Rows)
{
ChkBox =(CheckBox(rw.Cells[0].FindControl("chk"));
if (ChkBox.Checked)
{
chkCount++;
}
}
i wrote the above code to check whether the checkbox inside a grid is checked or not but although the checkbox is not checked the above code is returning checked true is all the cases....

Use this
int checkedCount = 0;
foreach (GridViewRow row in gvData.Rows)
{
bool result = ((CheckBox)row.FindControl("CheckBox1")).Checked;
if (result)
{
return true;
}
else
{
return false;
}
}

i do have 2 gridviews in my page, both of which contains check boxes. i need to uncheck and enable second gridview when any of the checkbox from first gridview is selected and vice versa.
|
|
|
|
|
Here is a demo example, i m takin two grids and than disabling and enabling the second one through checkbox click in first one through javascript.
.aspx code
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<input type="checkbox" id="chkitemheader" name="chkitemheader" onclick="SelectAll('chkitemheader');" />
<ItemTemplate>
</asp:TemplateField>
<Columns>
</asp:GridView>
<asp:GridView ID="GridView2" runat="server" style="visibility:hidden;">
</asp:GridView>
Javascript:-
function SelectAll(id) {
if(document.getElementById(id).checked)
{
var grid = document.getElementById("<%= GridView2.ClientID %>")
grid.style.visibility = "visible";
}
else {
var grid = document.getElementById("<%= GridView2.ClientID %>")
grid.style.visibility = "hidden";
}
}
</script>

thanks , but i need to enable asp.net checkbox inside gridview .
|
|

1. You need to put a javascript function in each checkbox in row in first gridview. in that checkbox you call the javascript function as follows
<asp:checkbox ...... OnClientClick = "return EnableBelowGrid(this.id)" />;
2. Following would be your javascript function defination
function EnableBelowGrid()
{
var chkBoxID = arguments[0];
if(document.getElementByID(chkBoxID).checked)
{
document.getElementById('<%=BelowGridID.ClientID%>').disabled = true
}
return false;
}
Assumed that "BelowGridID" is the ID of your below grid as you have refered.
Thanks,

 What is this ? Can you please write it in English ?

It appears to be txt-speak French. Interesting, haven't seen that before. Asking for help with a final year project I think?
I'd rather set a challenge for an application that could translate that.

I used some online tool and paste his text over and translate to english. It comes like :
"A student i ss as CDA creation and development of application intranet, extranet and my project of end of study and a blend between discussion forum and site training numriser and courses video upload and download ben if quilqu a little m help if you plez"

I think this is what JHizzle did if he is not French (his profile says so  ).
But still it doesn't make much sense.

Nah, my french is pretty good but even so, I only got something about a final year project for his course and pretty much turned off after that.
|

|

Yeah of course. txtspeak in French 
I thought it's only English that got affected.

Hi all,
In my project, Parent page opens a child page using window.open method on a button click.
Child page has a method LoadDropDownList() in page_load, which is supposed to populate a drop down list in the page. LoadDropDownList method creates an object of a class from the referenced library and calls a method on that object which performs some heavy operation to get strings and populate the dropdownlist. This takes around 3-4 seconds. I release the object in the finally{} block in this method.
Now, Even if my child page is closed using (X button) immediately after its opened (before 3 seconds), the loaddropdownlist method is already initiated.
After that I open the child and close it immediately for 3-4 times aproximately and then the next time parent page is unable to open child page . IE 7 just shows running status. Probably Server experiences some heavy load due to multiple LoadDropDownList ongoing runs in the stack.
Is memory leak is happening here?
Shouldn't it stop running child's LoadDropDownList() and get read of the objects immediately after I close the form? But it's not happening. I found control returns to this method multiple times after i (opened for number of times and) closed the form respectively.
What is the remedy here? How child should stop running any method in it after it's closed?
Kind regards,
Vijay

Closing the browser does not tell the server anything. So the server still does all the processing initiated by the request as if nothing happened. It is not a memory leak from the browser point of view. But if only 3-4 calls to this process of yours are enough to slow down the server you really need to evaluate that method and figure out how to optimize it.

Vijay you say that you have a function that Binds the DropdownList. i have few questions for you.
How many times does this function call appear in your code ?
Do you Protect that Function against unnecessary post backs by doing something like
if(!Page.Ispostback)
{
}
The Slowness of your page might be caused by a lot of things , please give us more info and tell us what you are doing or share a part that binds the dropdown

This is a major issue which you cant do anything. Actually ASP.NET runs in request response approach. so whenever you call the server to get the dropdownlist, you are actually creating a new thread to send your request object from your browser.
Now after receiving the request object to the browser, until it sends back the response, you dont have any communication between the client and the server. At that moment, the browser shows something like "Waiting for Response... ".
If you close your browser the processing will not stop and hence your server will keep doing processing.
I think one option might be useful in this regard. You might cache the result for few seconds, so that the same request when received within a minute, it will be served from cache, rather than go and process it again. This would improve the performance of the page (only if the data is not very big)
I hope Caching would be the best solution for your problem, as there is no straightforward way to stop the thread running in the server before sending the response.
