Web Forms :: Accessing Web Part Property Using JavaScript?
Mar 15, 2010
I need to access a custom property of web part(that wraps an ASP.NET user control) from JavaScript. Is it possible ? I need that property value so that I could pass that to an AJAX web service then.
i have a usercontrol with a few dropdownlist....n i am using that usercontrol in few pages and depending on pages those dropdownlist can be enabled mode or disabled mode.
so i created a property:
[Code]....
Now i am accessing in HTML as
[Code]....
it seems to work.
Just curious know that am i going in right direction or any better approach is available?
So here is the problem , Is it possible to get the "SelectedItem.Text" of a binded dropdownlist? because everytime I'm getting null Even though I'm having items in the dropdownlist.
I'm getting the items that I want in the dropdownlist but I can't find out which one is selected.
There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?
On my web part page I use a JavaScript timer to call a Page Method to check if data has changed and then only I refresh the page. Now I want to disable that JavaScript timer when the web part page is in shared personalization mode. Then when web part page is again in BrowseDisplayMode, I want to reenable the timer to poll for updates. How do I access web part manager personalization mode in the client side JavaScript ? Do I need to use a hidden file in UpdatePanel ?

I'm trying to access the Data text Field value of a HyperLinkField inside of a GridView Control during the databind event. Normally, I could access any cell's value with some syntax along the lines the following in the RowDataBind function:
myVarText = e.Row.Cells(2).Text
But this doesn't work when trying to access the value of the hyperlinkfield. All that's returned is an empty string.

So in my website, I use jquery to fetch data through ajax. AS part of the ajax response, some of the javascript code comes as well which is executed. The problem is how to debug this javascript in firebug or other tools. This is my experience so far: putting debugger; doesn't work For some javascript, can't set the breakpoint as that script is not yet loaded. even if this new javascript calls some other function thats already loaded (i.e. i can see it in firebug and set a breakpoint), that breakpoint on that function is still not triggered However, the javascript does executes normally and even things like console.log works but cant seem to debug it.
Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'. In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment

We have several asp.net web applications we've built and we also want to embed them into various sharepoint pages. We need to have them look like standalone applications when viewed in their own pages, but also have them look like they fit within the sharepoint page when embedded. We are doing this currently with IFrames and it works ok, but I'm wondering if there is some sort of proxy web part where we can configure the web part to point to an existing web app and it will proxy the contents through from the web app into the sharepoint page removing the need for an IFrame. Possible?
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?

When using SPWeb.GetCatalog(SPListTemplateType.WebPartCatalog), it returns an SPList which of course contains a SPListItemCollection of the web parts in the web part gallery. When looping through the items, is there any easy way to get properties of the web parts? Such as AllowClose, CatalogIconImageUrl, etc... I know I can probably accomplish this using the listItem.OpenBinaryStream etc and loading the xml of the .webpart file, but I wondered if there was an easier way to do this.
