AJAX :: User Control Inside Updatepanel?

Sep 14, 2010

I have a custom control created to autofill the box as typed in. Its working great. But if I put the control inside an Update Panel, it works for the full postback but if partial postback happens (because of the update panel), it does not work.

AJAX :: How To Control Inside UpdatePanel Menu

May 28, 2010

I started a new project using VS2010. I have a menu control connected with an XML datasource inside UpdatePanel, Menu control works fine, problem is the styling. using a StaticHoverStyle Css works only after the page reloads, when I click a menu entry, the entry is selected but StaticHoverStyle does not reflects the menu items anymore (of course when I hover the items) Same behave with both Net versions 3.5 and 4. When I remove the UpdatePanel the StaticHoverStyle comes back to life ( post back occurs ).

AJAX :: Literal Control Inside UpdatePanel?

Aug 5, 2010

I should probably say I love these forums, I've been viewing for some time and have found loads of valuable information. I'm having a problem with my project, I have an updatepanel containing several items (Two Daypilot Schedulers and a Literal Control). I have set it to conditional and have it update whenever bookings are added/modified in the schedulers. This all works perfectly! I then have a literal control which contains div items with onmouseover= parameters. The control basically contains a list of pending booking requests. On Page_Load I call a method which populates the list...which works fine.

However, whenever I call the UpdatePanel.Update() method (say, when a booking is added), the schedulers update but the literal control does not. I have gone through the debugger and found that the LiteralControl.Text property is correctly set to the new updated list just before calling the Update() method. So basically it all works perfectly apart from the literal control not updating along with the schedulers in the UpdatePanel.

FileUpload Control Inside Gridview (ajax Updatepanel)

Mar 11, 2011

I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.

Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.

The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this

Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
'todo: this part is not working
If f.FileName.Length > 0 Then 'returns 0 always
'this returns 0.
end if
if f.HasFile() then
'this also returns false
end if
Next
End Sub

This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:

<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />

AJAX :: Chart Control Vanishes After Showing Up Inside UpdatePanel With 2 ModalPopupExtenders Present Ins?

Dec 6, 2010

Explaination in detail I have a tree view control on left of my page and AjaxToolkit:TabContainer on the right,consisting of 9 tabs in it (I have developed individual controls and added to the tab panels). On selecting a value from the tree view control the I am refreshing the values inside all the tab panels. There is a method reload written on all the controls which are called on tree view click which sets the value of the selected tree item in properties in all the controls and also refreshs them. Its a big performance issue for sure which i need to improve on but that would come later.
My problem

1. In the Main tab (ascx control) consists of asp:chart control which I am populating and it also consists of 2 buttons in which ModalPopupExtender would open up another 2 controls on button click within this control. Now on the tree view click I am calling
the reload of Main Tab which internally called the reload function of these 2 controls also

On Tree view click

Maintab.reload
{
ModalPopupExtender1.reload
ModalPopupExtender2.reload
}
Secondtab.reload
Thirdtab.reload
If I populate the asp.chartcontrol without reloading the ModalPopupExtender1.reload ModalPopupExtender2.reload it works great but when I call both ModalPopupExtender1.reload
ModalPopupExtender2.reload it shows up and goes away.

Any thing i am missing on ? How to make chart control stay on the page and not vanish. I tried making it visible again. The main page contains a chart control which comes and goes away and does not stay only if i comment out the reloading of these usercontrols it stays visible with values on the main page else goes away.

2.Performance problem- I am not sure how to lazy load the content inside the tab panels so that controls should have the selected item for tree view click and can populate thereon.

3. This is how I call my user controls to reload on the treeview click from within the main page.
PEGeneralInfoPortfolioProfiler1.PortfolioCode = strPortfolioCode;
PEGeneralInfoPortfolioProfiler1.ReloadControl(1);

AJAX :: Showing A Control On Click Of Linkbutton Column Of Gridview (present Inside UpdatePanel)

Jan 8, 2010

I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.

On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?

I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).

AJAX :: Dynamic Loading Web User Control With Gridview Updatepanel?

Jan 8, 2010

Wasn't quite sure where to post this, seems like the issues could be any number of things, so I'm trying to keep it general... mods, feel free to relocate appropriately.

I am trying to build a page which will load various web user controls dynamically in response to menu selections made by the user, and then allow other interactions inside those controls (such as gridview manipulation and updates). The content page simply has a loginview, an ASP:Menu control, and an ASP:Placeholder. The placeholder is filled by the appropriate user control in response to the menu selection. Selecting a menu item causes a postback and the correct control is loaded as expected.

I realized that using dynamic loading with interactive controls would be a problem with respect to postbacks, so I added a ScriptManager to the content page and enclosed the gridview controls in the web user controls within UpdatePanels, thinking that all postbacks required by the GridView would be handled inside the UpdatePanel and not cause the parent page to refresh (which would then wipe out the dynamically loaded control). However, it does not seem to work this way. Instead, although the control containing the GridView loads correctly and displays data, when I attempt to page, edit, or select any item on the GridView, nothing happens on the first click. If I click on any item inside the control a second time, the entire page refreshes and the control and its contents disappear.

I have removed all the code inside the web user control and placed it directly into the content page to test, and everything functions correctly in that case. I think therefore that I must be missing something with how the user control is working, particularly with respect to the UpdatePanel. Is it just not possible to use an UpdatePanel to confine actions inside a user control that would otherwise cause the entire page to postback, or am I missing something somewhere?

AJAX :: How To Get An Array Of All The Textbox Control Inside Create User Wizard Control

Aug 10, 2010

How can I get all the textboxes inside a create user wizard control using getElementsByTagName().

Below is my JQuery code:

[Code]....

The above code isn't displaying hint text when the textbox retreives focus.

I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .

But no one of them gets the textboxes array.

Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?

AJAX :: Editing Image Inside DetailsView Inside UpdatePanel?

Oct 4, 2010

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.

The source code:

<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

AJAX :: User Control Inside A Tabpanel?

May 11, 2010

I have this code:

TabSecciones.Tabs.Clear(); //the panel container
TabPanel nuevoTab =
new
TabPanel();
encabezadoSeccion encabezadoSec =
new
encabezadoSeccion();
//A user control, a couple of labels and a table
nuevoTab.Controls.Add(encabezadoSec);
TabSecciones.Tabs.Add(nuevoTab);

For some strange reason, the user control is "outside" of the panels, thus visible no matter what panel is selected... if I programatically insert another control (ie: a texbox) inside another panel, it works fine...

User Controls Inside An UpdatePanel - Css Styles Are Gone When Updating (IE8)?

Jan 30, 2011

I have an user control inside an UpdatePanel. Once an event is triggered and updates the user control - it seems to lose its css styles. This happened to me in IE8 only, while in Chrome and FF it was fine.

A user control for example:

[Code]....


In Chrome and FF it seems to be working as expected (button click causes current time to display in the user control, nothing else happens), but in IE8 the div inside the user control loses its styles (background color, borders). What could be causing this problem, and what can be done to prevent it?
