Maybe you can rephrase your question and provide a working codeblock?
I'm trying to understand the problem, but unfortunately, i'm failing.
In general, if indeces of selected items cannot be retrieved, i would double check
the databinding on that listbox. if the listbox is rebound on that postback, you may lose
the selected item indeces.
try putting your databinding in an "if(!IsPostback)" block - if youre binding of course.
Good Luck

Hi everybody.
I need some help with a problem.
Can anybody say what's wrong with my script?
When executing, IE says that there is an error on the line with the __dopostback.
I do not have knowledge on javascript, but I copied the code and made it work sometimes.
Right now, I'm going crazy with it. Thanks in advance.
<script language="javascript">
var sFeatures='dialogWidth: 500px;dialogHeight: 200px;status:no;scroll:no';
var Resp = window.showModalDialog('PopUpMsg.aspx', window,sFeatures);
if (Resp == True)
{
__doPostBack('btnBorrar','1');
}
</script>
It is supposed to show a modal window called PopUpmsg.aspx, where I'll answer Yes or No. That works fine. But after answering, I need to reload the page, and the postback does not seem to work.

Might be due to this browser cache. Are you uploading images with same name. If yes, try every time new name.

Dear,
I have created html textboxes in GridViewDataRow. I created html textboxes dynamically. I have given the IDs dynamically. By default the textboxes should be disabled. When I click linkbutton outside the gridview with onClientClick event, a javascript function should be called and then all the textboxes in gridview should be enabled. Please help me in implementing this. Help would be appreciated.
Regards,
Dileep.

Why are you creating textbox dynamically. Its better if you it to be always there, show and hide according to your requirement in rowdatabpound event of gridview.Store the Ids in some hidden field and in JS function, itereate through all the IDs and make them enable.

Hi,
Please try the following:
<script language="javascript" type="text/javascript">
function EnableTextBoxes() {
var gv = document.getElementById('GridViewID');
var objs = gv.getElementsByTagName('input');
var i=0;
for (i = 0; i < objs.length; i++) {
if (objs[i].style.display == 'none') {
objs[i].style.display = 'block';
}
}
}
</script>

Jamil

Iterate through the grid view from javascript, find the textbox either by tagname or by Id and enable it like this,
txtBox.disabled=false;
Let me know if it works.

Hi guys,
I'm currently experiencing a strange phenomenon.
I have a user-control which allows the user to add data into a list on clicking on the OK Button.
On the page where I use this control all works fine.
However, now I need to have a second page where i need to enter the same data. So I wanted to re-use the control.
The control is shown but when I click on the OK button no event is trigger, nothing happens?
I have put a break point in the PageLoad of the user-control, but it doesn't event get there.
It seems like that the event if any is missing at all, althought that the html (client-side) code is the same.
Does anyone have a thought, or knows a reason why this could happen?
Thx,
Kurt

Thanks for the reaction,
but the markup and the code behind is more then 2400 lines,
The real problem is that is have inherited this project from some other company which failed to deliver on time. And now I have to 'Make it Work, ASAP'.

Are you loading the UserControl dynamically? if yes then you must re-load it on Init event of the page.
let me know if you need any further help.

Jamil

As far as i know the control isn't loaded dynamically.
<visitcontrol:SimpleVisitorControl ID="BadgeControl1" runat="server" />
Is used to get the control on the page.
To show the Control it is call by a client side script.
badgeCallbackPanel.PerformCallback("");
Which is the same code as on the working page.
On both pages the control is shown in a 'popup' but on one of the pages the OK button doesn't work.
