Serverside Controls Vs Html Controls From AJAX Point Of View
Mar 8, 2010
i know this question have been mentioned alot here but mine is a little more updated, now with ASP.net 4 and new Ajax client templating plus JASON services. so if i got all these new capabilities will i really need server side controls as long as i can bind on client side, create data-views on client side heck i can even use data-context and apply CRUD operations on clients side.
so i actually i wont need button_click server side event or what so ever... i am asking this because i own some commercial Controls like Telerik and Component art and they both offer client side operations ow but still i am confused as to my knowledge creating these controls will still have to go through Page Life cycle
I have an aspx page that is getting an Object Expected javascript error on submit, but when you break into the error the breakpoint is somewhere in the middle of the __VIEWSTATE input html element.A javascript stack dump shows just "{anonymous}(null)".What does this mean and how does one go about debugging further?
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:
I can't seem to figure out how to set a breakpoint in a Razor view. I understand why that might seem a little weird and may be difficult since a cshtml file is a combination of html and then c# code, but I can step into it. The ability to step into it makes it seem like I should be able to set a breakpoint. Am I missing how to do this or is this not possible in the RC? If not any plans to add this before RTM or in the future?
n my application i am using ajax html text editor control , its working fine . but the contents that is typed in html editor contains bullets and numbering and while i am filling this content to a label control then the nuembering(ordered list) and bullets are not shown , is any solution ?Is it possible to view contents only by using ajax html control in preview mode.
I want to build a high traffic video site, which has many videos and visitors, using ASP.NET. But I have no experience of high traffic sites and video sites. Anyone can give me some stuff to read or some keywords for me to google? In the performance point of view.PDATE: I said our site is similar to Youtube, but that just meant that the site structure would be similar to Youtube. We won't have that high traffic.
How can i give validation to all controls (like textbox, radiobuttonlist, checkbox, fileupload) in my aspx form in server side.... and also validation for controls with regular expression in serverside...
on the server side created cell content for my GridView that have html anchors. However when the page is emitted all I get is the entities in the Source and the anchor tags show up in the gridview instead of the hyperlink.
This seems like it should be extremely simple. I have a list of x,y cords in SQL table that I am pulling out into a reader. I am then trying to bind my points to a point (have to use it since I can't find scatter) chart control.
Where Xpos = the x cord column and Ypos = the y cord column.The chart generates but my problem is that I am getting multiple x values that are the same. For example I have (67, 45) and (67,54).I would think there would be one x value for 67 with the two points on it, at 45 and at 54.Instead I am getting 2 x values listed, both for 67, one with 45 and one with 54.
Just as a test I listed these values in excel (in 2 columns) and did a scatter plot and it generated what I expected (2 items plotted on the same x value, one above the other. Is there a setting I am missing or does the chart control "Point" not have this capability.
FOr this i Used __doPostBack but page flickering is occured eventhought if we keep update panels,
I have a gridview control from gridview I am calling RowCommand event and then a Popup Page from Popup i will return some values and again i need to bind the values back to the DataTable and then to GridView.
In JS if i User doPostBack('xyz','') page flickering is ocurred and if i user doPostBack('updatepanel1','') ID also flickering is not occuring bt values gets binded to GRidview after 5 sec delay....
is ther any alternate sol for this to do...
any Jquery or any JS???
or if i use ScriptManager Page Method is there any issues with that bcz we need to have a static method in server side.....:(
You'll have to excuse my ignorance, I'm coming at this from a front-end perspective, and don't really know how to deal with data views in ASP.NET.
Basically, I'm trying to change the layout of some repeated data from a straight table, to something more design-heavy. It's the same data, just re-organised slightly. The current ASP.NET code looks like this:
[Code]....
However, I want to replace all of this, such that each 'row' of data renders like this:
[Code]....
How is this done? Can I just edit the code above, or would I need to do something more advanced in terms of not using a data grid and using some other control instead? Is it something that can be done in just a .aspx file or would it need to be done in C# and compiled?
I'm having asp.net ajax tab container in a datalist control with 4 tab panels. I set ActiveTabIndex to 0 on .aspx page, and using OnActiveTabChanged event in code behind, when the tab container tab index is changed, server side event is not working, when i debug the code, i can see the event is getting fired, even though i click the third tab, i'm getting Active TabIndex "0" only.
<cc1:tabcontainer id="TabContainer1" runat="server" AutoPostBack="true" Font-Names="Calibri" ActiveTabIndex="0" Width="710px" CssClass="yui" align="left" OnActiveTabChanged="TabContainer1_ActiveTabChanged"> Server Side Code:
[Code]....
I need to load data only when tab index changes, this way i can reduce burden on whole page.
i am using a modalpopup extend in asp.net using ok and cancel buttons

I'm trying to develope a collapsible panel control with designer.
I have the following two classes:
[Code]....
and this one:
[Code]....
In fact, the designer class is a copy of a sample class in MSDN and I only tried to customize it to work for me. I'm not sure if all methods are necessary or not.
I have the following two questions:
1- When I use this contrl in design mode, I can add or delete controls to it, in the html view, tags are not updated. so when I close the page and open it again, all changes are lost.
2- I have added this control to the same asp.net project that is using this control. Isn't there any way to have this controil in tool box?
We are plannning to use Ajax in our ASP.net project.. But we still want member panel of our web site to work in all browsers, So we have decided not to use Ajax in some forms where browser independence is must.. N I am now confused with whether to use ASP controls or HTML controls or both? And which 1 is better considering efficiency and performance...
I am displaying a Modalpopup programmatically with todo_modalpopup.show() in serverside code. The Panel's Style is set to display:none.. But when I click on the target control id (which is inside the Grid) , the panel loads fully in the page itself and then displays the modal popup.
would like to build a chart that will focus on the point plot. which mean every first point index is plotted will show in the chart as more and more chart plotted those point already been plotted will move to the back of the chart so the user only see the latest point is plot in the chart,anyone try this before in mschart ? can we add scrollbar, slide show or something for user to view the past plotted chart ?
Can the standard ASP.NET Visual Studio validation controls display an icon with a tool tip message instead of text, the way the WinForms ErrorProvider controls work? If not, is the AjaxToolkit's ValidatorCallout control the best approach? Is this control flakey?
I have a user control embedded in a web part. It has the following snippets of code:
[code]....
Why are some controls initialised and others not? How do I get around this if I'd like to update the Text property on currentPageLabel?
Update:
I've placed breakpoints all the way through the page life cycle and found that nextButton and currentPageLabel are never initialised. The breakpoints were placed at OnLoad, CreateChildControls, goButton_Click, OnPreRender, Render and OnUnload.
I have several gridviews on an aspx and each has a hyperlinkfield. All of them redirect to another page with a single gridview. I am trying to figure out how to get each hyperlinkfield to redirect to the actual point on the receiving page with the corresponding value. In the sample data below, I need to be able to click on 'def' and open aspx page 2 to the point on the page where 'def' is located. All values still need to be visible. Can anchors be used in gridviews?
