AJAX :: ModalPopup As An .ascx Control To Be Triggered By Hyperlink?
Sep 29, 2010
I have found a couple of good topics here in the forum and wanted to see any other extra ideas for this control that I am making and trying to implement. So here is the basic information:
The control is going to display a SQL output in a bunch of label controls. The information is going to be coming from a gridview control where the field is going to be hyperlinked.
So I am wanting to set the "TargetControlID" property to the .ascx page load event.
now what I have found is that I can simply run the Popup.show(); function in the .cs file at the end of the page load, but I still have to place a valid control within the TargetControlID property. As you know, the property cannot be "null" and if I put in the control ID for something that is not valid, then it won't work either. So the only thing I can think of is tying it back to the overall control itself. Then I can always change it on the fly if needed, but I think I would not have to since it would fire on the page_load event...
Not sure if this is making any sense... Just understand that have to make this control go across several web pages that are already fully developed. I am just adding this in as new functionality...

I have a page that has a few requirements1. A Gridview that is dynamically populated (and refreshed at a regular interval) with a button control that is conditionally displayed 2. The button control should show a ModalPopup of a Panel that serves as a form 3. This Panel form contains a textbox populated with a value from the gridview and another dropdown control I can get 2 of these 3 requirements via a couple of different approaches (like 1+2 work, but 3 fails or 2 +3 work but 1 fails).The code pasted below is the closest I have gotten, and is actually my preferred method, and I was wondering if anyone could tell me why the ModalPopupTextBox1 is not rendered when ModalPopup button is clicked.If I place the Gridview1 outside of UpdatePanel1 (refresh controlled by Timer1), the ModalPopup Panel works as expectedMarkup: GridUpdate.aspx

This is an ASP.NET 3.5 app. The page has the following controls in this order: GridView with Select button enabled UpdatePanel, which containsA trigger pointing to the SelectedIndexChanged event of the GridView A child DetailsView that displays the record of the selected item in the GridViewUpdateProgressSelecting an item in the GridView triggers the UpdatePanel and the record displays in the DetailsView, as expected. However, since the GridView is outside of the UpdatePanel, the UpdateProgress doesn't display while the record is being retrieved. If the GridView is moved inside the UpdatePanel, everything works as expected but for several reasons it needs to be outside of the UpdatePanel for this app.
There are several articles about how to trigger the UpdateProgress display. Most involve using a button, which has an OnClientClick event, that can be used to trigger some javascript to change the display style of the UpdateProgress. Unfortunately, there is no client side event for the GridView so no way to trigger the javascript. Any ideas on how to display the UpdateProgress when a GridView item is selected? Here is a trimmed down version of the controls involved:

Most of the solutions found on the internet and in this forum made use of javascript triggered by a button. Pretty much all of the javascript followed along these lines:

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?
At the moment, the only pseudo logic for this I can think of is?
'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)
'Try to find the user control as a child of the update panel

I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null.
ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked.
rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here [URL]

I am quite new to asp.net. I would like to ask for some advice on how this scenario can be achieved. Here is the problem:
I have a 5 gridviews on my page. In each gridview, I have two important columns. They are SellerID and BuyerID. Because I already have too many gridviews on the page, I want to load a webuser control with a modalPopupExtender when either SellerID or BuyerID is clicked. That is to say if a user select a SellerID, the details information about that SellerID should be loaded with DetailView from the user control and if the buyerID is click, the details information about that buyer should be loaded with another detailview
from the user control as well.
My problem is I do not know how to get the Selected Value from the gridView since the DetailView is in the WebUserControl. One more thing, both SellerID and BuyerID are in the same GridView, so how can we distinguish when a user select a SellerID or vice versa.

I have a user control that contains a modal popup extender.
I am using the user control inside of a repeater so it could be shown multiple times on a page.
Everything works fine if the repeater only contains one item.
When there are multiple user controls on the page I get the following error:
"Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'PosAdjPopup' can't be added to the application."
How do I get my user control to work with the modal popup extender when it will be used multiple times on a page?
Can I keep the modal popup extender in the user control or do I have to put it on my aspx page and trap the event on the button click?

I have three modal popups that are working properly because I test it the controls with simple plain text.
I placed a form view and a datalist in the first two modal popups and everything seems to be okay.
I need to place a user control in the third modal popup but everytime I place the user control I get a javascript error for that particular modal popup.
When I copy paste the same modal popup on a blank page and place the user control inside of the panel then the modal popup works perfectly fine.
I basically copy/paste the same code back where the other two modal popups are then I get the same JavaScript error.
The modal popup crashes first on:
this._popupElement.parentNode.appendChild(this._foregroundElement);

I am using a modal popup control which contains an UpdatePanel. There are one combo and few text boxes and Calendar control in it. When I select any item in combobox, then it's selection change event is fired and there iI set the values of other controls and finally I call update method of update panel. Functionality wise it works properly but it takes a time to update the panel.Here combobox contains around five thousands of items. But when it contains 100s of items it works good.

The target control is a Button (ID = "btTest");
The following is in code-behind:

The click has been verified, but the popup does not show. Of course, if btTest is manually clicked, the popup will show without any problem.
Is there any way to show a popup window from code-behind?

I have an aspx page with multiple modal popups. These modal popups are trigger in the page behind code using .Show() and .Hide().
This is what I have in the .aspx page for the particular modal popup under discussion:
[Code]....
The example below demonstrates the type of calls I am making to the modal popup extenders. Basically using the Datalist item command, the datalist commands are responsible for triggering my modal popups.
[Code]....
They all work fine after postbacks except the "activityReport" case (the last one). The only difference with this modal popup is that it contains a user control and all the postbacks are happening in the user control. So the problem is that in the last case whenever a postback happens in the user control then the modal popup is close.
1. If I separate the modal popup and place it in a page all by itself and trigger it to .Show() through a button click in the page behind code then the modal popup doesn't close. See below example.
[Code]....
2. The button click event in the test page looks as follow:

I have a master page which contains a Login control so that the user can login/logout from any page. However, a couple of content pages require a Recaptcha control. This causes problems because when I try and log in on a page that has the Recaptcha control, the system expects me to enter the words. I'm aware of the lack of validation groups in the Recaptcha control, and the fact that you can't have multiple forms on an ASP.NET page. Is there a way to work around this? A 'hacky' way I can think of, is in the "Login" event, check the page for a Recaptcha control. If one exists, then disable it, otherwise continue. However, that just seems quite inefficient especially when there are quite a few pages and most won't have a Recaptcha control.

I have controls and some has AutoPostBack set to true.
i.e
<asp:CheckBoxList ID="cblTest" runat="server" AutoPostBack="true"
OnSelectedIndexChanged="cblTest_SelectedIndexChanged" >
</asp:CheckBoxList>
How can I capture which control has triggered the autopostback event when it runs again in the Page_Load method.

I am trying to modify the Interval and Enabled properties via ViewState but it is not working.
Here is my code:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
//set the default Refresh Interval to 3 seconds and enable Timer to TRUE
ViewState["TimerEnable"] = true;
ViewState["RefreshInterval"] = 3000;
}
Markup:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server"
Enabled = <%# Convert.ToBoolean(ViewState["TimerEnable"].ToString()) %>
Interval = <%# Convert.ToInt32(ViewState["RefreshInterval"].ToString()) %> >
</asp:Timer>
...
If I use Enabled = "true" and Interval = 3000, the code works just fine!

I have a simple table with 5 text boxes, above that i have a dropdown where you make a selection, if there are any records of associated with the selection, then i display in the fields..
A while back this was working, you could make a selection and the fields were within a update panel and they were populated. But im revisiting the pages to make some updates and changes and noticing that the page no longer populates the fields when a selection is made..
Is there anyway to debug the updatepanel? I put a breakpoint in my selectedindexchanged event and my Db call is returning values and the textboxes .TEXT values are being assigned the right values in the code behind, but the fields never show up..
This page hasnt been touched since it was wworking last, so need to see how i can test / debug the update panel to determine what coudl be causing it..
