i am adding rows and cells dynamically to asp table control...and i wish to put extract a particular cell's of the row when clicked ...

I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.

View 1 RepliesI'm new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.

reading on the forums about assigning event handlers to controls that are dynamically created via code and am just not getting anywhere.In my particular case, I'm rolling through a directory of images and creating ImageButton controls on the fly and want to assign the OnCommand event to a single handler.Then, by using the CommandName (which is different for each control) I can figure out which ImageButton was clicked and act accordingly.
The snippet below (which can be found in many posts on this topic) is inside a foreach which loops through the directory and gets each FileInfo (fi).Each is then added to a PlaceHolder (phImages).
[Code]...
This code compiles and runs but the event handler is never invoked when an ImageButton is clicked. I believe this is because you cannot, without some coding I'm not familiar enough to do yet, assign a handler to multiple controls.I say this because I ran into a similar problem in a Silverlight app I wrote and had to use a lambda (=>) operator to do something similar (although I admit to not knowing enough about this to know if this situation is the same).

how to create user control dynamically in a web form ?When i am creating server controls of user controls are not instantiated and it is not getting initialized .when i am tyying to initialize its properties error occurs tha object instance not created .
View 6 RepliesI have a situation where I dynamically load one of twenty user controls at a time in an ASP.net web page. Based on much reading I've done, I understand that I am to reload the user control upon postback via the Page_Init event handler. This I've done and it seems to work fine.
But now I would like to wire up assorted controls in the user controls such that when the value of each is changed, an event is fired and the web page is notified. Here's an example of how I'm doing that:
userControl.NewData_Handler += new EventHandler(UserControl_NewData_Handler);
There's a problem though. Because the user control is being done in Page_Init (ie. before Page_Load) I don't believe that a line of code such as the one above can function yet.
So I'm wondering what the best practice to do this is. It occurred to me that perhaps I could execute the line in the Page_Load event handler but I'm not sure if that's correct or not.
Is it possible to use AJAX and an update panel and create server-side controls such as checkboxes, buttons, and radio buttons (asp server side) that is created when another server-side control (that which exists outside the update panel) calls them?
secondly, how do you keep them from re-appearing after a postback?
When I do a postback, the controls in the update panel disappear.
Due to the size of content, I would like to dynamically create tab pages on a page dependant on user action. Also, I would like to have the ability to allow the user to close/dispose of the tab pages. Is there anyFREE user control that can do this?
View 1 RepliesI'm trying to develop a web application where there webpage would contain a list of Web control (textbox, label, calendar...) images on the left (as a menu), and the user would be able to drag any of the images onto a specific space within the page and it would dynamically create that specific control (for example, if the user drags an image of a TextBox into a panel, then a TexBox control would be dynamically created into that panel). Basically, I need to reproduce the basic drag-and-drop functionality of an IDE. To be honest, I have no idea how to do this.. anyone can point me in the right direction??

I would like to find out if there is anyone who would know how to read from a database then returns the same number of records that a stored procedure returns and display those records on the webpage there after pass the ID of the record to a variable to another stored procedure that displays the data related to the record that was clicked, I tried doing this in a asp.net repeater but I can't seem to be able to reference the controls inside the repeater.

I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.

I am using Repeater control. In DataBound event I am preparing output of item and everything works ok. But now I need to add a command button to item. I cannot add button to item template in designer (some project specifications do not allow it). I create new button at DataBound, set unique ID, command name and argument and bind it to command event and, thenm place it to Item controls container. It is not working as command button.
