Web Forms :: Removing The Border Style For Dynamically Created Image Controls?
May 21, 2010
sometimes we need to use the asp image control so we can generate empty alt tags (visual studio 2005 does not render any attributes set
to an empty string). I know how to do this and also how to remove the border style that is automatically added
We implemented this 6 months ago, however, only today have I discovered that it does not work when images are created dynamically.The first implementation was for asp images that have been set up within an aspx page:
The above works-no border style is rendered and the imageurl is populated in code.I have other pages where I'm building up sections dynamically using C# code, such as:-
i have a gridview that directly bind to a dataset.Hence there is no column in code behind for me to control the boarder color and border style.I try my code in RowDataBound, but it does not take effect.
--------------------------------------------------------------------------------------------------------- using System; using System.Collections.Generic; using System.Linq;[code].....
but when i use this, the border for header of the TabContainer also removed.as per my requirement i have to remove only the left,right and down border of the control and header will remain the same.
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I am working on reporting services 2005. I have a problem setting table cell(textbox) borderstyle.Some cells are for 'Amount' summary, so I want to set those cells' top border as 'Solid' and It works, but at the same time, the table's top border is set 'Solid' as well, that is what I don't want. I only want to set the cell' border. So how should I do?
<asp:RequiredFieldValidator ID="RequiredFieldValidatorOnlineID" runat="server" ControlToValidate="TextBoxOnlineID" ErrorMessage="Online ID is required.<br />" ToolTip="User Name is required." SetFocusOnError="True" Display="Dynamic" CssClass="validationerror"></asp:RequiredFieldValidator>
Rendered Server control code:
<span id="ctl00_ContentPlaceHolderSYLMainMaster_RequiredFieldValidatorOnlineID" title="User Name is required." style="display:none;">Online ID is required.<br />
I have tried the following to remove the style attribute with no luck:
I don't need and want the style attribute, how can I prevent it from being written into my code? It messes up the alignment of the error message with my textbox.
My validation controls don't line up with my textboxes because I can remove the inline styles, how can I make style=display:none disappear?
<span id="ctl00_ContentPlaceHolderSYLMainMaster_RequiredFieldValidatorOnlineID" title="User Name is required." class="validationerror" style="display:none;">Online ID is required.<br />
I want to make a textbox with a specific style, within this style a set of images as background parts, how can i attach these images to the custom control as whenever i take the .dll file and add it to the toolbar the images do not appear. So i tried to make them as resource files and their property as embedded in .resx file, so how to make the css style background image url to be linked to any of those image.
I have put a hoplink inside an image like this. This is a test but when looking at the banner that is shown you can see a gray border along the banner (GIF).
Is it possible to get rid of this gray border that is around the actual banner here ?
I have a tree view with checkboxes for leaf nodes. If i click on checkboxes, I am creating some html controls dynamically. And in other static button click event I need to get an ID's of those dynamically created controls.
I need to create web controls (e.g. label etc) dynamically.The problem is that for example,
on my onload event, I create a label. The text of the label is read from one line of a xml file.
But sometimes the text should be like " Messages (4)", in which the message count is something not generic and need some logic to calculate. I tried to put things like "Message (<#% MessageCount %>) " in my xml file, but the displayed text label is:
Message (<#% MessageCount %>) instead of Message (4 ).
I was looking through my transcender exam kit for 70-562 and they say load dynamically created controls in the loadviewstateEvent. This should be CreateChildControls() instead, no?

I am building a webform dynamically but when I go to get the values the placeholder has no controls. Every control added has an unique ID. Does anyone know what I am doing wrong (language is C#).
I'm using a DataPager for a ListView, it works well, I'm using ButtonType:Image to style it but I want to change the image while mouse over, but I can't, I've tried some with ButtonCssClass but there's no good result. Here is my DataPager:
[Code]....
So, is it possible to change the image while mouse over?
I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1 'use a try to target the button, use catch to handle if it's instead a label, only one cell per row. Try Dim accountLink as Button = tblAccountList.Rows(x).Controls(0) Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck Catch ex as InvalidCastException Continue For End Try Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
have some code which dynamically generates a number of drop down lists to provide the user with different options. The items in these drop downlists contain a value which is a unique id for that particular combination of options and a text component which just plain text but not neccessarily unique. I then have assigned a handler to these dropdownlists which is called on selected index changed to perform the relevant actions based on what options are selected. The problem is to make the system perform the correct action I need the unique ID from selectedValue of the drop down box but when it posts back it appears the selectedValue has been replaced to match the text of the item.
Dim dynDdl = New DropDownList() dynDdl.ID = "ddlOpts" & i dynDdl.AutoPostBack = True AddHandler dynDdl.SelectedIndexChanged, AddressOf dynDdl_selectedIndexChanged [code]...
