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);
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).
My problem is very simple: I have a chart inside an UpdatePanel (I'm using AJAX) and 2 RadioButton in which AutoPostBack=true.When I click on my "generate chart" Button, the chart is well painted on the page but the AutoPostBack of my 2 RadioButtons seems to stop firing. That is to say, after painting, If I click on my RadioButton the postback doesen't works!I need to set some kind of trigger related to the chart?
I have 1 ModalPopupExtender inside a UserControl. Everything works great until I start adding the same usercontrol to the page. I am getting this error message in the javascript console::
Message: Sys.InvalidOperationException: Two components with the same id 'MPE1' can't be added to the application. I understand the error, it obvious that the framework wants unique IDs. What I can't figure out is how to give them unique name.
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.
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.
I have a CheckBox that is located inside a SelectItem Template. The CheckBox has Autopostback= true. Located outside the list view is a label. When the CheckBox is checked, I would like to trigger an the Updatepannel that includes the label. Instead I get an error message "'CheckBox1' could not be found for the trigger in UpdatePanel 'UpdatePanel3'. The code snippet is as follows:
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:
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.
protected void OnRatingChanged(object sender, RatingEventArgs e) { SqlConnection con = new SqlConnection(connStr); SqlCommand cmd = new SqlCommand("Insert into rating(rating,postid) values(@rate,@pi)", con); cmd.Parameters.AddWithValue("@rate", e.Value); cmd.Parameters.AddWithValue("@pi", Request.QueryString["ID"]);
[Code] ....
The rating value get inserted to database async but updated rating is not displayed after update. I have to refresh page in order to display updated ratings.
I'm using an asp.net chart control to display a pie chart, image below.

I can't find the property (I assume there must be a property) to get rid of the whitespace surrounding the chart. Does anyone know how to? I feel like I've tried everything...
I'm trying to put Google's BarChart and PieChart both the client side version, and i'm experiencing some problems with the labels over the pie and the labels on the left of the vertical axis (of the bar chart).
I checked the code a lot of times and it seems to be like that you can see in the examples.I've tried the same page on Firefox and Chrome and it shows the labels without problems.If i try the examples on IE8 the labels are shown but not in my page.Sincerely I've not any idea where to start to fix this thing.
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.
I either don't understand or I'm not using AJAX right. I'm running a long report. I'd like to have a label to show the user that the "Report Running", then, that the report has finished. But, when the user runs another report, I'd like to have the label that shows "Report Finished!" to clear so that you don't have "Report Running!" and "Report Finished!" on the screen at the same time. But, the label will not clear???? I get both lables showing. What am I doing wrong?
In my web application, i have declared modalpopup extender and corresponding div(popup control) inside master page to make it generic. In my page i am using updatepanel with a button inside it. Clicking on this button will fire the modalpopup extender. Before calling show() of modalpopup i am setting some text to a label inside the popup control. But when the popup comes, the updated text is not showing.
I'm trying to implement Google Interactive chart inside an updatepanel.
The regular Google Charts do work (I think because there I'm just calling an URL).
But now I want the interactive chart inside an updatepanel within a tabcontainer etc. But now the request to Google is made, resulting in an infinitely loading white page to Google.
A project I own was just moved from an older server to a new one, and in the process of moving the web folder, re-deploying the SSRS reports, restoring the database, configuring IIS, etc... I have lost the ability to view the Microsoft Chart Controls that are embedded in the SSRS reports, that are then displayed by a Microsoft.ReportViewer.
I could view them both locally and remotely (via the internet) on the old server. I can view them if I preview the SSRS report in Visual Studio. The report displays fine, only missing all the embedded charts. I can still view them locally through the web browser, just not from the internet.
I tried giving permissions to the ChartImageHandler temp storage folder, but it didn't work.
I'm getting the Javascript error: Error: ClientReport380ec8ca0c294a809e9986c1bef9db1c is undefined
I'm having problem with MS Chart chart type column. If there are only 9 bar in the chart like the following picture, then the axis-x label show up properly.
However, there are more than 9 bars bar the chart, the axis-x label wont show up properly, some of them just dissappear.
Here's my mark-up for the chart:
[code]....
I don't know it works with only 9 bars? Is there any way to make the chart work properly? Also, if possible, how to make each bar have different color.
