I have a vertical menu placed on top of (z-Index) a background image. The background appears nicely on my development server but does not appear on the production server. I have deleted all folders and file from the appropriate directory on the production server and copied all files and folders from the dev server to the production server to no avail. I figure that there must be a setting blocking this functionality on the production server or perhaps that older version (Server 2003) does not support this function.Oh, I have been attempting to add 2 PNG images to this post but cannot succeed.
The Get of the Visible property of a control recursively looks up the tree to indicate if the control will be rendered or not.
I need a way to see what the "local" visible value of a control is regardless of what its parent controls are set to. i.e. Whether it itself was set to true or false.
I have seen this question, How to get the "real" value of the Visible property? which uses Reflection to obtain the local state, however, I have not been able to get this working for WebControls. It's also a rather dirty method of getting the value.
I have come up with the following extension method. It works by removing the control from its parent, checking the property, then putting the control back where it found it.
public static bool LocalVisible(this Control control) { //Get a reference to the parent Control parent = control.Parent; //Find where in the parent the control is.
[Code]....
Is this an acceptable way of doing this? It works fine and I haven't come across any performance issues. It just seems extremely dirty and I have no doubt there could be instances in which it might fail (for example, when actually rendering).
I'm working on a .NET 3.5 web application which shows/hides table rows contained in ascx files via an interface implementation (the controls containing the table implement the interface).So, given this markup in the .ascx:
I want to set the value of a session variable to a hex color code in the Global.asax, then use the value of that session variable (hex code) as the background color in the default.css file.
I 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? Maybe some sort of If gridview1_rowdatabound = 0 then...
What do I have wrong here? This page is essentially broken into 5 divs, the middle 3 divs that represent the left, middle and right page columns are wrapped in a div with the id content. I linked to the page if you want to view the source. It wouldn't go in this message as a snippet very well when I tried.
Here is the style for #content
#content { background-color:White; }
How do I get the whole background of #content to show as white? link to a live version of[URL]
I have a Sidemenu item in my ASP.NET application like below. There are two types of users in my application (Associates, Managers).When ever Associate Login then I have to disable Manager link. I am not able find visible property in codebehind since it is a HTML control. So need your support how to handle this
This was originally posted, in error, to another forum. Not sure how that happened. Anyways, here goes... I have a web app that uses javascript functions to make rounded corners. One of the functions requires two colors as parameters. I cannot change this function definition. My web app is in asp.net 4.0 and uses master pages and themes. To facilitate programmatic access, I moved all javascript declaration into the code behind file of the master page. It gets generated in the load event: I declare it there as a big string (using StringBuilder) and then put it into the page with Page.
ClientScript.RegisterClientScriptBlock(... Now that I have introduced themes into my application, I have discovered a serious problem. These themes each utilize their own CSS and skin files to paint the various elements of the app's web pages in different colors (of course). But remember, as parameters, one of my javascript functions requires two colors. And now that I have themes I can no longer manually code these colors into the javascript declaration... Now I have to discover a way to extract the background color and one other color from the current theme's CSS file. Then I can feed that into the javascript declarations in the master page's PageLoad event in the master page's code behind file. This would allow the javascript function to be called on the page load and to use the current theme's colors as parameters.
"'ErrorMessageResourceType' property specified was not found."
{"The resource type 'XXXX.XXXXXX' does not have a publicly visible static property named '_RequiredXXXX'."}
I'm getting this error when my Create.aspx view is called and steps over that line:
<%=Html.TextBoxFor(Function(model) model.NO_DEMND, New With {.class = "txtbox", .disabled = True})%> <%=Html.ValidationMessageFor(Function(model) model.NO_DEMND)%>
The message is there in the Ressources file, I think the problem is deeper than that but i'm having a hard time finding it. It pops this error very early on the ASPX page. It's the first model component it goes thru, i tried removing this one and it's the same message for all the model.xxxx components. I guess it's an error somewhere in the linkage. The .EDMX is correct and I get no build errors,
I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:
I'm building a custom web control with a public property which I only want to be available in design time (i.e. make it unavailable in code behind). The DesignOnly attribute promises to do just that, but when I set [DesignOnly(true)] it has no noticeable effect whatsoever:
[Bindable(true)] [Category("Appearance")] [DefaultValue(null)] [Localizable(false)] [DesignOnly(true)] public string MyProp { get { return ViewState["MyProp"] as string; } set { ViewState["MyProp"] = value; } }
The property still appears in code behind IntelliSense. Setting a value to it in code behind works. In these respects, the behavior is just as if the attribute had never been set. And I've cleaned and rebuilt the complete solution. Twice.
I'm writing ASP.NET custom control, and I want it to have a few properties which should be visible only from code behind during run-time - I mean, these properties should not be visible both in a designer and in a aspx code of page containing this control. I've tried to use following attributes:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] [Browsable(false)] public List<Item> SomeData { ... }
but unfortunately this property is still visible in an Intellisense combobox when editing aspx page. Is it possible to hide this property everywhere besides server-side code ?
I want to show some panel with a label, both located on a MasterPage, from inside it's child pages.. I already did the coding on the MasterPage:
public class MyMaster : MasterPage { public void ShowPanel(string pMessage) { labelInside.Text = pMessage; myPanel.visible = true; [code]...
This "works" ok, but it won't show nothing, since I need the page to be "refreshed" in an "ajax-way" like an UpdatePanel, which I can't use because the Trigger is in another page, right?I really need this to work.. even if you have another completely different way to do this,
I have a database field called ImageLocation, I have the ImageUrl property bound to: Eval("ImageLocation", "{0}")I would like to bind the Visble property to false if the ImageLocation is null data. I can not figure out how to set the control properly, currently the Datalist shows me all the data and when the image location is null it shows me the name of the Hyperlink control which happens to be Hyperlink2.
