Web Forms :: ImageButton Command Event Inside A UpdatePanel
Apr 28, 2010
have a created a dynamic solarsystem map. Basically I have a updatepanel which inside I programattically create imagebuttons of the 'planets'. These imagebuttons are given a Command event and when clicked the idea is to set the clicked planet in question as the parent and redisplay the map.Inside the command event I pass in the ID of the planet and this sets a session varible. The panel load event is then designed to use this session varible to set the new parent and display the child 'moons'

I am having a custom ASPX page with following structure. Its having 2 update panel and I have a ImageButton outside them. The two UpdatPanel are triggered by this ImageButton.The Problem is whenever user clicks the Imagebutton, the image in the ImageButton is getting reloaded...it disappears and the reappears. I am not able to figure out why the postback is happening when the imagebutton is place outside UpdatePanel. Is it because I am using this Imagebutton for triggering AsyncPostBack in UpdatePanel?

I've got a textbox being used to enter a password inside a wizard control. I'm trying to get a password strength meter working with it.
Unfortunately, the password box isn't visible until step 4 and this means that I can't register the event handler onload() and putting some JS next to the PW box to register the event handler doesn't seem to fire. I'm guessing this is due to the contents of the wizard being loaded through an AJAX postback.

I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects
checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator)
2. Click the Linkbutton (fires two validators)
3. Uncheck the checkbox (which should disable requiredfieldvalidator)
4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.

I have a div with "id=ShowDetails". In my javascript I have this:
$(document).ready(function () {
UIactions();
});
function UIactions () {
$('#ShowDetails').click(function () {
alert("bingo");
}
});
The div is inside the update panel that gets posted back. When the page loads, if I click the div, I get the bingo but after the postback, I don't.

I'm designing a sort of hierarchical system, as follows:
Contract
Master Commodity
Commodity
Sub-Commodity
Part
Each one of these are on their own page (for now). The user starts out on the Contract.aspx page. If they want to see the Master Commodities for the contract they are currently on, they will click the "ImageButton" I have set up, and I pass in as a command argument the ContractID (CommandArgument='<%# Eval("ContractID")%>'). This works great- I get to my Master Commodity page with the Master Commodities filtered on the ContractID I passed in.
Here's my problem: Navigating from the Master Commodity page to the Commodity page will (I think) require passing in the ContractID (so we JUST see stuff for the contract we're on), AND the Master Commodity ID (so we JUST see the Commodities that are related to the Master Commodity). I've tried the following: CommandArgument='<%# Eval("ContractID") + ',' + Eval("MComID")%>', but as you could probably expect, that doesn't work. If I can just do something like above and have a delimiter like the comma, I can go from there and make it work.

I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?
Complete code is below:

why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?

I created a form in a popup div, that contain an UpdatePanel with ImageButtons in it.Initially, I used LinkButtons to test but I wanted ImageButtons. The thing is, it works well with LinkButtons and not with ImageButtons (absolutely nothing happens).

WebForm_PostBackOptions("ctl00$cphC$ctrlAdr$AdrMapo$lbAdresseSaisie",

I have an asp page that has an iFrame. In the onload event of the iFrame, the javascript code copies the content of the iframe to the div. The iFrame has src="test.aspx" and hence displays the content of the test.aspx inside the div.Test.aspx page contains and imageButton, which does not show up in the iFrame.I am getting the following issues:1. the image does not show up (cannot see test.gif)2. When i click on the imagebutton link, it tries to search for test.aspx in the directory where the asp page resides inside of the actuallocation/directory of the aspx page.
