when using asp.net´s visible=false e.g. for a htmlgenericcontrol asp.net renders a newline for a control that is set visible=false.
How to prevent this behavior?
I just have a
<ul> and then
<li runat="server" id="x"></li>
<li runat="server" id="x"></li>
<li runat="server" id="x"></li>
So one <li> per line. If I set one or all li´s to visible=false by code I get newlines instead of "Nothing"
there is a way to make a label visible for a seccond and then make it visible =false ; ?without javascript... just c# ,,,
View 4 RepliesI have a code below in my gridview.
I want to set the HeaderText to Visible = false on my code behind. Can i do that?
[code]....
If I have a grid, and it is binded to some data, but the visible=false for the grid, will it consume any resources for initializations or for retrieving data to perform the bindings?
How about if the grid is inside a div, and the div visible=false
If a control (say a label or textbox) is set to visible = false then
1. Is the value specific for each user(like session) or for whole application?
2. If it is user specific, then how is the value kept across multiple Http requests? is it by session management(cookie or URL rewritting) or viewstate?
3. If it's by viewstate, does that means users still have chances to modify the 'invisible' control's value?
4. If it's by session management, I can't depends on the 'invisible' control's value unless I am 100% sure cookie or URL rewritting is working, right?
i have create user control to add the new city, where i entered the name new city, select the related country from combo and select the related state from combo and click on save button.
View 4 RepliesI have an ASP.NET text control "FromDate" whose visible property is set to false, but I wanted a client side javascript to be able to toggle the visibility property using CSS properties
element1.style.display = "none"; // hides the element
element1.style.display = ""; // shows the element
but when I attempt to get the textbox, I get null on
var element1 = document.getElementById("FromDate");
When I try the same code with visble=true as the default on the "FromDate" ASP.NET control, it works (although that is not the behavior I need)

I have the following simple code:

So when i select "Yes" from the first drop down, the "hiddenDetail" label becomes visible and when i select "No" from q1 the "hiddenDetail" label becomes invisible.The problem is that because i am using AutoPostBack when you select "No" the "hiddenDetail" loses its children (i.e. the label inside it) which is obvious why but i am wondering, is there anyway i can make the "hiddenDetail" invisible (sort of like display:none in style) in VB without losing its children.

View 10 RepliesI have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?

View 1 RepliesI have a form with a ton of gridview controls on it. All of which are driven by a dropdown list control. When I select a value from the dropdown list control it populates the 5 gridview controls with data from the database.If there are no rows associated with the record from the dropdown list then I am going to set the visible property of all of the gridview cotrols to false.
I know how to set the property I just need to know where I would set it and what I would check.I can put my code in the selectedindexchanged event for the dropdownlist control but how do I check to see if there are no rows associated with that value?

' RowCommand
Dim f_iIndex As Integer = Convert.ToInt32(e.CommandArgument)
Dim f_oSelectedRow As GridViewRow = grdMeterCorrection.Rows(f_iIndex)
Dim f_oCertIdCell As TableCell = f_oSelectedRow.Cells(11)
Dim f_sCertId As String = f_oCertIdCell.Text.Trim
If e.CommandName.ToLower = "void" Then

The problem is the CertId field in the GridView has visible set to false. I think this makes the value unaccessable to the RowCommand.
I'm trying to make my TD visible or not inside a repeater. I keep getting an error "Object reference not set to an instance of an object". here is my code:
[Code]....
and my code behind:
[Code]....
I know it has something to do with how my findcontrol code is written, but I can't figure it out.
I combined MVC and DD by creating a new DD project and adding the MVC stuff (references, routing, usings, etc). The list of tables on default.aspx (from DD) will show all tables, including the ones with [ScaffoldTable(false)]. The URL's of the tables with Scaffold==true have the expected form (DD/TableName/List.aspx). However, the URL's of the tables that should not be shown are in the form /Home/List?Table=TableName. If you leave out the MVC routing (Routes.MapRoute) then the tables with Scaffold(false) are not shown. Or you can leave out only the Parameter defaults.
My guess is that Dynamic Data determines if a table is visible by checking to see if a route can be made to for the List page. The DynamicDataRoute will not match because that will not generate a route if Scaffold==false. BUT THEN the MVC Route WILL match because of the Parameter defaults at the end. Am I correct and is this a bug or am I completely missing something here? EDIT: I fixed it by adding filtering the VisibleTables on Scaffold like this, but that's a workaround...
System.Collections.IList visibleTables =
MvcApplication.DefaultModel.VisibleTables.Where(o=>o.Scaffold==true).ToList();
My RegisterRoutes in global.asax.cs:
public static void RegisterRoutes(RouteCollection routes)
{
DefaultModel.RegisterContext(typeof(studiebase2Entities), new ContextConfiguration() { ScaffoldAllTables = false });
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.Add(new DynamicDataRoute("DD/{table}/{action}.aspx")
{
Constraints = new RouteValueDictionary(new { action = "List|Details|Edit|Insert" }),
Model = DefaultModel
});
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
