AJAX :: AutoComplete Control Popup Truncated From EO.Web Grid Control?

Apr 13, 2010

I have implemented AutoComplete Ajax control inside EO.Web Grid Control similar to this one:


I have this this code:


The good news: It is working successfully !

The bad news...

I am facing the following problem.

When the AutoComplete Ajax Control gives the Popup Box after typing few characters in the "CustomColumn" input, and if the grid row is near the bottom of the grid, the popup box will be truncated, or it will not be shown at all. This is becuase the height of the popup is bypassing the bottom edge of the EO.Web Grid Control.

I am sure this can be solved by styling AutoComplete Control. I tried to change the style, and it is now completely messed up.

How I can ensure the the AutoComplete Popup Box will be visible even if it is near the bottom of the grid ?

AJAX :: Modal Popup Click Control Within Panel Is Closing Popup

Jul 27, 2010

I'm using modal popup extender and panel with calendar in it. Click the "Next / Previous Month" closes the modal popup. How do I tell the modal popup to ignore click events in a calendar control inside the panel targeted for popup? I'm confused because when using extender before, you had to click OkButton or Cancel to close popup. I have update panel for reason. I just minimized the code for easy review.

AJAX :: Template Based Custom Control For Ajax Modal Popup

Jun 15, 2010

Lets say I have a user control AjaxUC.

<asp:ModalPopupExtender ID="modalSearch" runat="server" TargetControlID="btnHiddenSearch"
PopupControlID="pnlModalSearch" DropShadow="false" RepositionMode="RepositionOnWindowResize"
Drag="false" BackgroundCssClass="modalBackground" >
<asp:Button ID="btnHiddenSearch" runat="server" Style="display: none" />
<asp:Panel ID="pnlModalSearch" runat="server" CssClass="modalPopup">
<asp:Panel ID="pnlModalSearchContent" runat="server">
<asp:Label ID="lblSearchTitle" runat="server" CssClass="modalPopupTitle"></asp:Label>
<div id="divContent" runat="server">
<asp:Button ID="btnModalSearchClose" runat="server" Text="Close" CausesValidation="false"
OnClick="BtnModalSearchCloseClick" />
<input type="hidden" id="hdVisible" runat="server" />

------------------------------------------------------------------------ AjaxUC.ascx.cs:-

public partial class AjaxUC : System.Web.UI.UserControl { private ITemplate _content = null; [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(Container))] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate Content { get
{ return _content; } set
{ _content = value; } } void Page_Init() { if (_content != null) { Container container = new Container(); _content.InstantiateIn(container); divContent.Controls.Add(container); lblSearchTitle.Text = LblModalSearchText; } } protected void Page_Load(object sender, EventArgs e) { if (hdVisible.Value=="true") { modalSearch.Show(); } } } public class Container : Control, INamingContainer { internal Container() { } }}
This control when used on any aspx page will popup the control placed inside the template "divContent" as modalpopup.
Now I am trying to convert this user control to Custom Control and my code is:-

[ParseChildren(true)] [PersistChildren(true)] public class DNAWebAjaxTool : PlaceHolder { public event EventHandler BtnModalSearchCloseClickEvent; public event EventHandler Click; private ITemplate _content = null; private HtmlInputHidden _hdVisible; private Panel _pnlModalSearchContent; private Panel _pnlModalSearch; private ModalPopupExtender _modalSearch; private Button _btn; private DivContainer divContent = new DivContainer(); private string _viewState; public DNAWebAjaxTool() { } public Panel PnlModalSearchContent { get
{ if (_pnlModalSearchContent == null) { _pnlModalSearchContent = new Panel(); } return _pnlModalSearchContent; } } public ModalPopupExtender ModalSearch { get
{ if (_modalSearch == null) { _modalSearch = new ModalPopupExtender(); } return _modalSearch; } } public string ViewState { get
{ return _viewState; } set
{ _viewState = value; } } public HtmlInputHidden HdVisible { get
{ if (_hdVisible == null) { _hdVisible = new HtmlInputHidden(); } return _hdVisible; } } [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(DivContainer))] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate Content { get
{ return _content; } set
{ _content = value; } } protected override void OnInit(EventArgs e) { _content.InstantiateIn(divContent); base.Controls.Add(divContent); base.OnInit(e); } protected override void OnLoad(EventArgs e) { if (HdVisible.Value == "true") { ModalSearch.Show(); } base.OnLoad(e); } void _btn_Click(object sender, EventArgs e) { BtnModalSearchCloseClickEvent(sender, e); } public virtual void Hide() { PnlModalSearchContent.Visible = false; ModalSearch.Hide(); ViewState = "false"; } public virtual void Show() { PnlModalSearchContent.Visible = true; ModalSearch.Show(); ViewState = "true"; } protected override void CreateChildControls() { base.CreateChildControls(); } protected override void Render(HtmlTextWriter writer) { if (ViewState == "true") { _modalSearch = new ModalPopupExtender(); _modalSearch.ID = "modalSearch"; _modalSearch.TargetControlID = "btnHiddenSearch"; _modalSearch.PopupControlID = "pnlModalSearch"; _modalSearch.DropShadow = false; _modalSearch.RepositionMode = AjaxControlToolkit.ModalPopupRepositionMode.RepositionOnWindowResize; _modalSearch.Drag = false; _modalSearch.BackgroundCssClass = "modalBackground"; _modalSearch.Show(); _btn = new Button(); _btn.ID = "btnHiddenSearch"; _btn.Style.Value = "display: none"; _btn.RenderControl(writer); _pnlModalSearch = new Panel(); _pnlModalSearch.ID = "pnlModalSearch"; _pnlModalSearch.CssClass = "modalPopup"; _pnlModalSearch.RenderControl(writer); PnlModalSearchContent.ID = "pnlModalSearchContent"; PnlModalSearchContent.RenderControl(writer); divContent.RenderControl(writer); _btn = new Button(); _btn.ID = "btnModalSearchClose"; _btn.Text = "Close"; _btn.CausesValidation = false; _btn.Click += new EventHandler(_btn_Click); _btn.RenderControl(writer); } } } public class DivContainer : Control, INamingContainer { internal DivContainer() { } }
The problem I am facing is that the modalpopup extennder is not coming up as a popup.

Ajax Control Toolkit Popup Style?

Jun 29, 2010

I am converting across an old popup system from an older app into a newer one and want to take advantage of the ajax control toolkit to do all of the popups.

Unfortunately the business will require me to make the popups look like the old version (essentially just another page opened in a smaller window and showing the title bar). The problem I can see with using the ajax toolkit is that there is no "title bar" that gets included with it as its not really a new window.

AJAX :: User Control In Modal Popup?

May 11, 2010

At the bottom I have couple of buttons that call a modal popup to add new user to a grid.Now when I click on add user button it opens a modal popup. In that modal popup I have a add user control. Aslo In that add user control I have some jquery validations, autocomplete etc.Now when I open my modal popup it loads my user control in modal but none of my javascript is fired. By fired I mean if i start typing in my autocomplete textbox or even validate some fields none of my js is fired. I do have the jquery file included at the top of my user control. This page works fine if i create a simple aspx page and call my user control from there. But somehow when I call it from modal it screws up. Also even if I place a simple alert('Hello') on my user control that also does not fires (just wanted to make sure jquery is not the prob)

AJAX :: Dynamically Created Popup Control Extender

Apr 5, 2010

Im trying to dynamically create a popup control extender for labels which are also dynamically created. the labels are one a dynamically created accordion pane. Here is a section of my Page_Init method:


When I run the site with this code I get the following error:Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.Parameter name: element

I thought it might be because the target control ID changes during compilation so i tried to find the labels in the Page_InitComplete method with this:[Code]....

The expression in the FindControl argument is what the id of the label looks like when i view source in my browser after running the page.I also tried to use the popup control's DynamicControlID property, but im not sure what the DynamicServiceMethod is for.

Ajax Modal Popup Loads Behind The Activex Control?

Aug 4, 2010

In a page there is an activex control as well as a button whose onclick opens an ajax modal popup. The problem i face is that whenever the button is clicked the ajax pop up loads behind the activex control and thus it is hidden.So I am not able to use that control at all. I have not found a proper solution to this. I tried a solution where a browser check condition was removed from the ajaxtoolkit code. but no luck. Am using Ajax toolkit version 3.0.30512.1.

AJAX :: Pressing Enter Causes Calendar Control To Popup?

Apr 7, 2010

I have a page where the calendar imagebutton and extendar are the first button on the page. I notice that when I hit enter on any of the fields (textboxes) that the calendar will open. How can I prevent this?

I tried setting a default button for the form, which works, but it then causes another problem in that it fires my validators when I hit enter on a field that triggers a button other than the default button. For example, I have a lookup field with a button and if I hit enter on this field the validators will flash quickly because the default button is the submit button and it's trying to submit the form.
