Im using VS 2008 and have created a Visual C# ASP.Net Web Application and have a Table on the Page (Created at Design Time).
Im Trying to add rows at runtime when the user presses a button but it creates one row then none after.
[Code]....
I am showing data from different databases in a web part. Would it be possible to dynamically add and remove that data including the layout that that <DIV> has and would I go about in doing this?

and Test.ascx has the following event
[Code]....
How can I add this part OnEvalCommand="Eval_Command" to the control at runtime. I am familiar with setting properties but not events.
to duplicate an already existing <div> with its existing controls multiple times on one form. I have a situation where I have a group of controls contained in one <div>, but the user might need to add more information in the same format so I would like to just have them click a button to add another component and the same set of controls will be duplicated below it.
View 6 RepliesIn my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?
View 3 RepliesI am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I need to have a siteMapeNode for a menu control to only show up during development.
The following node would be in the web.sitemap file.

I can either put this node in my web.sitemap file and remove it in release builds.
Or Add the node in debug builds.
Probably done in PreInit or Page_load events.
I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.
Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.
I have the Gridview setup to show table2 data.
I created a field template and inserted my dropdown list and linked it to my table1 data source.
When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.
posting the dropdown value from table 1 into the appropriate field in table2..
Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.
I'm trying to add some user controls on a page. Thats easy, I just do it like this.
UserControl block = (categoryblock) LoadControl("categoryblock.ascx");
Panel1.Controls.Add(block);
But i want to access the label controls and more that are inside the categoryblock.ascx. How would i do that? I cant do it like this,
block.l_itemName.text = "blabla";
I managed to user FindControl("l_itemName") but i would rather like to have the intellisense.
I'd like to add a control A (that exists on a page) to a Footer user control's panel. If I create the control A dynamically and add it, I don't have issues. But I would like to avoid adding this dynamically.So, I defined control A in the aspx page and in the code behind, I got reference to the footer's panel and did a Controls.Add() It works fine, but postbacks from this control has strange behavior (could be due to viewstate?) as it doesn't execute some code that is on the page with a !IsPostback condition

View 1 RepliesI have a table on my web form that I need to populate at runtime. I can do this ok and add controls to it, and all works well. However in between each row in the table I am trying to insert an empty row using the following:

View 6 RepliesI have have two radio button lists that need to be mutally exculisve, i.e when one is clicked the other one neesd to be cleared, my further problem is beause they are in a formview I had to add handlers to clear all the controls in the other list when the one is clicked and vice versa. here is the code below Now the code works but one of the testers found that if you click back and forth around twenty times you get the above java error:
Exception message: Maximum request length exceeded
my though here is the handler is being added to many times ? but even if I remove the handler after the process is complete I still get the same error.

I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?
View 6 RepliesI am trying to add a radio button click event at runtime.
Radiobutton button = new RadioButton();

I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.
In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:
If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN
I have an asp:Table and around the mid point of the table there is a DDL with values 2-5. What I want to do is add the selected amount of rows using AJAX right after the table row that has the DDL in it. I know how to dynamicly crate the rows, the info in the rows, and how to use AJAX to make things. Problem is I can not put the ContentTemplate tag inbetween the asp:TableRow which would mark the location I want the dynamic rows to start being added. I did some searching on here but most posts I find start with making the table from code and not the asp:Table tag
