I'm trying to show/hide panels in a masterpage depending on what page the user is on.

But it didnt work.
We have a dynamic sitemap and all nodes in the sitemap display a breadcrumb. Is it possible to have the breadcrumb still showing, but make the link in the sitemap invisible or non-clickable? Reason for this is that... we dont want users to select some pages from the sitemap (becasue they need to conduct a search first to populate a datagrid) and clicking on the link will only take them to an empty page. I tried just removing the url, or having a blank title, but that didn't work.
View 14 RepliesI have created a simple method to check if an image has been approved and finally returns it as an control. But how do i call and show it on the page? I've tried something like this in the aspx-file:
<% SendImage("DKBygMiniLogo.gif", "True"); %>
Here is the simple method:
protected Image SendImage(object Image, object Approved)
{
bool approved = Convert.ToBoolean(Approved);
Image img = new Image();
if (approved)
{
img.ImageUrl = "~/images/Ads/" + Image.ToString();
img.Visible = true;
}
else
{
img.ImageUrl = "~/images/Ads/" + Image.ToString();
img.Visible = false;
}
return img;
}
How do I actually show the image?

Code:

document.getElementById("<%=UpdateProgress1.ClientID %>").style.display = 'none';

View 3 Replieswhat is the best way to show/hide controls in .net?
I have a page with many show/hide depending on the control value.
eg. radio button list rbl (dynamically generated from the database values)
based on the radio button list value,will need to show/hide the other controls.
if the value is 1, will need to show or hide dropdownlist1.
if the value is 2, will need to show or hide dropdownlist2.
I tried using the javascript with rbl.Attributes.Add("onChange","return toggleDropdown();")
then in my javascript function i will show/hide the control.
However when I toggle the dropdown for the second time, it became very slow. The first time is okay.
I have also tried using ScriptManager and UpdatePanel (putting the controls inside the UpdatePanel), but it is also very slow when toggling dropdown for the second time onwards, causing the page to hang.
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'
i have a detailsview and if the tick box field "controlled" = true then I want the edit button to be hidden.
