AJAX :: How To Set MasterPage Only Render ContentPage And Control Inside UpdatePanel
Mar 27, 2011
I have a DateTime in my MasterPage.aspx that is outside of UpdatePanel1. There are two Hyperlink controls inside UpadatePanel1 to navigate or to move to the other pages. Full code of MasterPage.aspx is below.
[Code]....
If the user clicks Hyperlink to navigate or move to the other page, the DateTime will change. It means that my MasterPage.aspx render the whole page when the user clicks Hyperlink. I do not want this behavior. I want my MasterPage.aspx only render the ContentPage and the
Hyperlink inside UpadtePanel1. Controls outside UpadtePanel1 like DateTime should not be rendered again. Please advise the code to achieve my example goal.

From a content page i am assigning a css class to one of the list item.
HtmlGenericControl home = (HtmlGenericControl)this.Page.Master.FindControl("mainMenu").FindControl("mainManage") as HtmlGenericControl;
string cssToApply = "current";
if (null != home)
{
if (home.Attributes.ContainsKey("class"))
{
if (!home.Attributes["class"].Contains(cssToApply))
{
home.Attributes["class"] += " " + cssToApply;
}
}
else
{
home.Attributes.Add("class", cssToApply);
}
}
and my css,
#header ul li {
display:inline;
float:left;
}
#header ul a {
-x-system-font:none;
color:#FFFFFF;
display:block;
font-family:Trebuchet MS,Arial,sans-serif;
font-size:1.1em;
font-style:normal;
font-variant:normal;
font-weight:bold;
text-transform:uppercase;
text-decoration:none;
}
#header ul a {
-moz-border-radius:3px;
-webkit-border-radius:0.2em;
padding:3px 7px;
text-decoration:none;
}
#header ul a:focus, #header ul a:active, #header ul a:hover {
background-color:#829E7E;
outline-color:-moz-use-text-color;
outline-style:none;
outline-width:medium;
}
#header ul a.home {
margin:0 16px 0 17px;
}
#header ul #current a, #headermenu #current span{ /*currently selected tab*/
background-color: #BCE27F;
color:#666666;
white-space:nowrap;
}
#header ul a.manage,#header ul a.enquiry,#header ul a.report {
margin:0 14px 0 0;
}
#home #header ul a.home, #enquiry #header ul a.enquiry, #report #header ul a.report, #manage #header ul a.manage{
-moz-border-radius:3px;
-webkit-border-radius:0.2em;
background-color:#B9E27F;
color:#FFFFFF;
}
But i get the error, System.Web.UI.AttributeCollection' does not contain a definition for 'ContainsKey' and no extension method 'ContainsKey' accepting a first argument of type 'System.Web.UI.AttributeCollection' could be found (are you missing a using directive or an assembly reference?

I have a masterpage with a timer that shows server time and refreshes every second, on the content page I have a chat program with ajax, refreshes every to second to get the last messages entered.
I have a Html TextBox and a hidden Submit Button, when user write a text, and hit the enter, I check to see if this is the enter key and then submit the message,it is working perfectly in IE, but in FireFox and Opera it show the same message twice. I think the problem is the Timer, is there any way to avoid the MasterPage timer in this particular content page?

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 ).

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.

We have a master page file in which we have a MenuControl. We are displaying some menus according to users credentials. We are handling MenuItemDataBound event inside master page for adding & removing menus.
There is user edit page{ContentPage} on which user may edit his own credentials. After saving the edited data {users credentials} by ASP.Net Button control, the MasterPage's MenuItemDataBound event doesn't fire (in case of refresh it is firing but in case of post back it is not firing).
We need to recreate/refresh MenuItems for master pages after saving the user and add/remove any nodes from Menus.

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" />

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);

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).

firstly,i am going nuts with this problem. here it is:
i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.
now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to
see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.
i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage
