View 1 RepliesWeb Forms :: Removing The Border Style For Dynamically Created Image Controls?
May 21, 2010sometimes 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
(http://blog.josh420.com/archives/2007/10/aspnet-image-control-border-width-inline-style.aspx).
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:
-<asp:image runat="server" id="imgMast1" GenerateEmptyAlternateText="True" alternatetext="" imageurl="" />
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:-
System.Web.UI.WebControls.Image featureImage = new
System.Web.UI.WebControls.Image();
featureImage.GenerateEmptyAlternateText = true;
featureImage.ImageUrl = imageSrc;
divImage1.Controls.Add(featureImage);
divImageFeature.Controls.Add(divImage1);
When creating controls dynamically like this, the solution describe above does not remove the border style.

View 2 RepliesSQL Reporting :: Barcode Not Displaying In PDF Export?
Jul 8, 2010I have created an SSRS report in VS 2008 that has a barcode on it. The report and barcode both view fine when looking at it via Report Viewer. It exports into Excel fine, and the barcode displays fine. However, when you export it to to PDF, the barcode does not show up any more. If I change the font to something other than barcode (which is 3 of 9), the value shows up fine.
So my question is, why will my barcode not show up when exporting the report to PDF, but shows up everywhere else?
Web Forms :: Use Dynamically Created Controls Such As A Checkbox List And Fill The Values Dynamically?
Sep 28, 2010I'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.

View 1 RepliesConfiguration :: Can't Save Barcode Image To Server
Aug 24, 2010So while working on my project on local system, i need to generate a barcode and save it to a folder then retrieve it to attach it in an email to send to user, i got the barcode generator code somewhere on these forums (thanks for sharing) and used it and it worked perfectly, generated the code as image, saved the file to a folder on the local system, retrieved and attached it to email and sent it with no probs.
Next, i uploaded the files to online server to go live, i test, no barcode is getting saved :S, i'm guessing it shouldn't be that easy, guess i have to do some stuff before i can save it to a folder on the server,
Here is the barcode generator code:
[code]....
At the same time, can you also include how to retrieve it for later use ?
currently i use this to retrieve it from the folder on local system:
<img src='" + this.Context.Server.MapPath("") + @"BarCodes" + getCode() + ".png' />

Accessing Controls Created Dynamically (c#)
Jun 5, 2010In my code behind (c#) I dynamically created some RadioButtonLists with more RadioButtons in each of them. I put all controls to a specific Panel.What I need to know is how to access those controls later as they are not created in .aspx file (with drag and drop from toolbox)?
I tried this:
foreach (Control child in panel.Controls)
{
Response.Write("test1");
[code]....
"test1" and "test2" dont show up in my page. That means something is wrong with this logic.
Dynamically Created Controls And Postback
Nov 18, 2010I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control.
When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it.In the aspx:
<asp:Panel ID="pnlFilter" runat="server">
</asp:Panel>
In the aspx.cs:
protected void Page_Init(object sender, EventArgs e)
{
LinkButton lb = new LinkButton(); [code]....

Web Forms :: How To Use AddHandler To Dynamically Assign Events To Dynamically Created Buttons
Feb 14, 2011I 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.
Web Forms :: Want To Put Code In Dynamically Created Controls?
May 28, 2010I 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 ).
How To Use Partial Caching With Dynamically Created Controls
Nov 24, 2010I have a control declared with PartialCaching attribute, like this:
[PartialCaching(60 * 60 * 12)]
public class MyControl : Control {

}
but I create it in code, using new keyword. The problem is that if the control is in cache I must not create the control again the next time, but I need to add the control to the page hierarchy, otherwise nothing is going to be rendered. What I need in pseudo-code is something like this:
if (myControlIsCached) {
var ctl = ???; // something that represents the cached control
// e.g. could be: new LiteralControl( myControlCachedData ) [code].....

Positioning Dynamically Created User Controls
Jun 17, 2010I have a set of dinamically created User Controls on the page. They are pretty small 170X120 px in size, but when the page is displayed, they are all one under the other. All styling is default, which means they should be positioned in normal flow. Is there any way to place them next to each other. This is not a problem when I dinamically create for standard controls, like a button or an image. Why the user control is different. This is the markup behind the control:
