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?
does anyone know how to access a webpart using the HTML Document Object Model? for example: for a given page which contains a webpart manager and a webpartzone.
[Code]....
I cant access the custom control using the HTML DOM Like this: HtmlDocument doc = HtmlPage.Document;
HtmlElement element = doc.GetElementById("HostTest");
HtmlElement element1 = doc.GetElementById("silverlightControlHost");
HtmlElement element2 = doc.GetElementById("WebPartZone3");
HtmlElement element2Parent = element2.Parent;
HtmlElement element3 = doc.GetElementById("SLRoomConsumerPart1"); //element3 does not return anything at all just Null!
all of the other elements are returned except for element 3 which returns a null! Any controls (regardless if it is a custom control, ASP control, Usercontrol . i tried it by replaceing the custome control with an aspnet button. i go t a null value as well) placed in the <ZoneTemplate> Tag of the <WebpartZone> is not returned using the HTML DOM. I find this stupid and pointless, as the whole point of a webPart is that you can place all sorts of controls in it :
customcontrols, usercontrols html controls, html server controls, aspnet controls and you cant seem to get access to those controls using the HTML DOM model in codeBehind
<asp:WebPartZone ID="WebPartZone3" runat="server" Height="90%" Width="
<ZoneTemplate>
<cc1:SLRoomConsumerPart ID="SLRoomConsumerPart1" runat="server" />
</ZoneTemplate>
</asp:WebPartZone>
HtmlDocument doc = HtmlPage.Document;
HtmlElement my_WeBpart_Element = doc.GetElementbyId("myCustomWebPartControl1")
can anyone point me to a solution or a work around as i am trying to access the dom from silverlight 3 but should be exactly the same as doing it from the webpart'shosting page's code behind. so that i can reference the controls inside my web part from the code behind of the custom page once i get hold of the webPart Element referece.
I created an Extender which has a custom property that drills down a list XML elements from an xml file, where users can select xml elements during design-time. This works perfectly fine. However, my code only has a hardcoded xml filename (source of the xml elements list) and I need to change this by maxing the xml file user-specified.
What I did is that I created another control (panel) which has a custom property that when clicked (through the ellipsis), it will allow a developer to select the xml file which is supposed to be the source xml file that the Extenders shall use. The filedialog from custom panel's property works perfectly fine.
However, my problem now is that when I drag-drop my Extender, I cannot find a way to get the property value of the custom Panel Control which contains the xml filename. I tried creating a static variable which I thought the custom controls can share but VS2010 is breaking.
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.
View 4 RepliesSo what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
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.
[Code]....
here is my aspx code:
[Code]....
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?

View 3 RepliesIam developing a custom checkbox control deriving from the 'compositecontrol' which i need to use it for a composite control purpose.
public
class
TngCheckBox :
CompositeControl
{
i have written the required properties which are working fine except the "checked" property. here is my code for 'checked' property. i tried both the below ways (commented one and not commneted) . the problem is the 'checked' value is not setting the value at the get set part of the property.its assigning the value at the design time , but when i check and uncheck its not updating the property value.which is resulting me wrong .

I have a custom control, inherited from Button. This is the class definition for the control and 2 properties:
[Code]....
I show you 2 properties, only to illustrate the problem.
as you see Aplicacion property is of a custom type Sistema, and Roles property is of type List<UserRol>.
The Aplicacion property is rendered well, this way:
[Code]....
The problem I have is with List<UserRol>. I couldn't get it to be rendered. I expeect to be rendered this way:
[Code]....
Finally, this is the TypeConverter and Editor definitions for the list:

The UserRol class is a typical class, without any special attributes.
I have discovered that when I use the custom editor for Roles property, the collection is not persisted. When I use the default editor for the collection, the collection is persisted.
I need to create one custom text box control which should be bind with data base.
I am referring following link...

Description("The text to display on the link."),

public virtual string DataTexValue
{
get
{
string s = (string)ViewState["Text"];
return (s == null) ? String.Empty : s;
}
set
{
ViewState["Text"] = value;
}
}
protected override void PerformDataBinding(IEnumerable retrievedData)
{
if (retrievedData == null)
return;
base.PerformDataBinding(retrievedData);
Controls.Clear();
nameTextBox = new TextBox { ID = "nameTextBox" };
foreach (object dataItem in retrievedData)
{
if (DataTextField.Length > 0)
{
nameTextBox.Text = DataBinder.GetPropertyValue(dataItem, DataTextField, null);
}
DataTexValue = nameTextBox.Text;

this.Controls.Add(nameTextBox);

View 4 RepliesI was able to acces an HTML element from my c# code this way:
Page.Request.Form["Name"].ToString(), where name was an html element:
<input id="Name" style="z-index: 102;" type="file">
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?

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:

View 2 RepliesI wanted to know whether this is possible or not. I have a page with a div. I populate div at run time with a HTML table I wanted to access that table to get the data back.

I'm trying to do something which to me seems like it should be simple, yet I cannot think of a simple way to do it.
I have a built custom control, that has a property I want to change based on a user's interaction with a second custom control. This second control will be a table of data, with an 'edit' link in the last column. I would like the control, when the edit link is pressed, to pass an ID and trigger some event so that I can assign this ID to the first control. My initial technique for building this (second) control was to create some code which will iteratively create some html based on a dynamic range of data selected by the user. I know that I could create some sort of link with a value in the query string, but I would like to implement AJAX and was hoping that I could enable this communication without changing the URL.
I have a custom class downloaded from internet. In this class, there is a properties where by the value can be either 0, 1 or 2 only and I MUST assign it during run-time. But some how, this assignment only work using VB, and not C#.
[Code]....
In C#, it the compiler said "missing cast or conversion...". But in VB, it works perfectly.
