C# - How To Hide And Show Silvelight User Control On Main Silverlight Control
Dec 26, 2010
I have a main silverlight control named MainPage.xaml in an asp.net web site.
I want to dynamically add and remove control at run time.
So, I have created another control Top10.xaml and added to selected canvas area on MainPage.xaml as described on this page(Click Me):
Now i need to modify Top10 visibility in MainPage.xaml dynamically when a button is clicked on MainPage.xaml using C# code in MainPage.xaml.cs.

I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?

I have a button on my gridview that makes visible another gridview nested inside a column. What I want to do is to use the same button to hide it again. I can already make visible my nested gridview, and I know to hide the gridview itself would be the same code again. The problem I have is setting my flag in order to control which branch of my if statement is executed. I tried writing this inside the button event bool flag = false; and then changed it to ture after the gridview is shown, but of course it re sets itself to false again, and the else bit is never reach when you press the button again.
Is there away where I can persist a flag that when the button is pressed one branch of the if statement is reached, and when it is pressed again, the next branch is run? I do want to use JavaScript because the page is already overloaded with it!! I am using a template field with a button set inside it, and thus I wish to use code behind posting back to the server

I am creating a function to hide all the gridview controls except the control whose name is being passed in the function.
Here this.Controls referes to controls present in the page (At compilation error is thrown although). I want to fetch all the controls of type GridView with Name property not equal to the one passed in the funtion.
Now after getting a collection of GridView. I want to hide all the grids
private void HideGridView(string gridToShow)
{
GridView[] result = from control in this.Controls
where control.GetType() == typeof(GridView) && control.Name !=gridToShow
select control as GridView;
foreach (var control in result)
control.Visible = false;
}
At comile time it shows me this.Control as invalid because it is not a collection.
How can I achieve this on a web application
EDIT:
private void HideGridView(string gridToShow)
{
(from control in this.Controls.OfType<GridView>
where control.Name !=gridToShow
select control).ToList().ForEach(gv=>gv.Visible=false);
}
Here is the code I wrote, shows me an error: GridView is a type but used like a variable (Compile time error).
And at where Invalid Expression Term 'where'

Is there a generic control that can be added to all aspx pages that checks for silverlight plugin and the version.. I know there is javascript and the silverlighthost object tag that accomplishes this. Is there an existing ascx control that wraps this functionality ? I need to be able to set the path to the xap on each page (via a property on the ascx control).

I have a nested accordion control for categories and sub-categories with a gridview to display the data. What I am trying to do is to hide the "Header Template" when sub-category is "Not Defined" but the results are usually inconsistent and seems like if i define HeaderCssClass, HeaderSelectedCssClass declaratively then it overrides the conditional css styles defined in code (c#) for OnItemDataBound event whereas if I don't define declaratively then css in code is not consistent.
I am not sure how to approach this or if I am using the correct event for this.
In the code - I used label's forecolor proprtery to match to the background as a workaround for now but not happy with it.
I can set lblSubHeaderId.Visible = false; which works consistently but then I still have this predefined HeaderCssClass, HeaderSelectedCssClass which is still shown as a placeholder/ just a horizantal line for the headers where lblSubHeaderId is set to false.
My structure is:
--AccordionCategory
-- AccordionSubCategory
-- Gridview
And here is some code:

I basically need some items in a grid however each item contains subitems so I need a +/- type button to show/hide them. Is there a control to do this or would it be easier to simply put them in a CSS table and use jquery or something similar to control the hide/show of subitems?

I have a listview and in each there is a dropdownlist and a textbox. The textbox is invisible. When I change a value on the ddl it fires the SelectedIndexChangedMethod. In here, if the ddl is certain value I want to show the textbox thats on the same row. How do I grab the textbox from inside this method?
Code:

OnPagePropertiesChanging="lvBillingQueue_PagePropertiesChanging" DataKeyNames="ID">
<LayoutTemplate>
<table width="100%" cellspacing="1" cellpadding="3" border="0">

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

We have a ASP.NET web application written in VB.NET where we build content programmatically during the Init event.
We make extensive use of user controls, building them on the fly, and I now want to start including SilverLight content.
Is there an easy way of embedding a SilverLight application in a control, and then instantiating the whole thing in code, in the same way as you'd programmatically add ordinary ASP.NET controls to a page?
The SilverLight component itself works fine when added to a page using the <object> tag but I really want to be able to reuse it elsewhere in code.
Since I'm expecting use of SilverLight to increase in our application, and the asp:Silverlight control seems now to be deprecated, I'm looking for an alternative way of wrapping the content.
