Details View - Change control rendering

  

Hi

i am currently using the CSSFriendly adapters and need to change their behavours.  I am currently using a detailsview control to generate a form based upon a table in a DB and that the detailsview generates the column automatically.

If a column in the DB is of type bool the adapter displays a check box but for all other types it displays a text box.  I want to be able to customize this and actually have some rendered as dropdowns.  Is this possible by updating the adapter?

Custom Control Design view error

  

Hi

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'


This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.


Property Code Example:

public string Text
        {
            get
            {
                string ret = "";
                object obj = ViewState["Text"];
                if (obj != null)
                {
                    ret = obj.ToString();
                }
                return ret;
            }
            set
            {
                ViewState["Text"] = value;
            }
        }


I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it

Change grid view from table to other HTML layout

  

Hi,

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:

		<table>
			<tr>
				<td>
                    <asp:GridView ID="GVMoments" runat="server" AllowPaging="True" AllowSorting="True"
                        AutoGenerateColumns="False" PageSize="20" RowHeaderColumn="FirstName"
                        SkinID="GroupSkin" DataKeyNames="moment_id" 
                        DataSourceID="SqlDataEditMoments">
                        <PagerSettings Mode="NumericFirstLast" PageButtonCount="20" Position="TopAndBottom" />
                        <RowStyle />
                            <Columns>
                                <asp:BoundField DataField="moment_id" HeaderText="moment_id" ReadOnly="True" SortExpression="moment_id"
                                    Visible="False" In

Custom tree view for navigating wiki pages

  
I'm creating an information resource on our intranet (WSS 3.0) using the wiki style format.  The only trick is, unlike a standard wiki, where all pages are directly under the parent, I want to be able to create a customizable tree view where some pages are nested underneath each other.  For example, this particular site talks about all of our different IT systems.  I'll have a wiki page for each system, then underneath each of those pages, there will be more pages for things like training, documentation, etc.  Even though all those pages are at the same level, I need to be able to nest them in a navigational tree view on the quick launch bar.  I suppose if there were also a way to nest the wiki pages themselves, I could just use the pre-packaged tree view.  Anyone have any ideas?

Applying custom CSS to the MOSS 2007 Calendar control Month view

  

hi,

I have a requirement to use the MOSS 2007 Calendar Control - month view is to apply a custom css to have a look and feel as per our requirements.

We tried applying the custom css to the MOSS 2007 calendar control - month view, it does take the custom css and applies it, but when i click on any date and come back to the calendar control, it changes the CSS of the MOSS calendar control back to the default one.

Let me know if anyone has any suggestion on  how to customize the calendar control for css for our intranet application.

Your response would be highly appreciated.

Use update progress control to change image control imageurl

  
UPDATE: Apologies for the previous formatting error - hopefully the post is now more readable... Hi I have a button with an image control next to it. Before the button is clicked, the image control "ConfirmedStatusImage" shows a "cancel.png" image. When the button has been clicked (and some other code successfully executed), then I change the imageurl for the "theConfirmedStatusImage" to show a "ok.png" image. Quite a bit of time can often pass between clicking the button and the associated code executing, so I have an ajax update progress control that shows a "bluespinner.gif" image while the page is updating after the button click. At the moment, the update progress updating image appears next to the "ConfirmedStatusImage" control. However, I would like to change things so that when the update progress starts, the imageurl of "ConfirmedStatusImage" changes from "cancel.png" to the update progress image (i.e., the "bluespinner.gif"). Then, when the update is complete, then the image should change to the "ok.png" image. My question is: how can I achieve this? As far as I can tell, the update progress control does not have any events that I can hook into. Also, placing the "ConfirmedStatusImage" inside the ProgressTemplate would not work either, as this only displays

Drag drop functinality not working on Explore View control for file containing special characters in

  
We have created a control which uses explorer view control for file drag and drop. This functinality works fine for a file having filename without special characters but it gives an error if we drag and drop a file having special characters in the file name. The reason for this is Sharepoint uses WebDAV protocol for file transfer to the Sharepoint document library and WebDAV protocol has limitation that it does'nt accept file with special characters. Please let me know the way how I can accomplish drag and drop of file with special characters in file name, onto Explorer View control with WebDAV.
