I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?

I'm trying to build a website for real estate listing. now the data would look like a datagrid. and while clicking on it, it should open under the clicked row the dynamic data related to the specific row. (like an AJAX accordion). this website for example ( ignore the language, couldnt find any better example [URL] Now, i've been told that this works by using "Dynamic Div Creation" which i have no idea how it should work this way. Is it possible to make it work by using an Accordion inside a datagrid? or what?

I have a two buttons ( button1 and button2 ), a panel ( panel1 ), a label ( labe1 ) on my Web page ( coded with asp.net and c# ). I want to create 2 textboxs on my page when I click on button1 ( button1_click ).
After that, when I click button2 ( button2_click ), I want to get data of textbox (added on runtime) and write them on label1.
This application is part of my master application. This is very important for me...

I had successfully created a functionality where I can dynamically add rows and columns to a asp table by creating/re-creating controls on every page load.
I have 2 buttons - Add rows and Add columns that, basically according to a asp.,net page life cycle, occur in the following order and work perfectly fine.
Page load is fired and controls along with their viewstate are recreated. In Add row button click event - I just create a new table row and add controls to each cell dynamically.
Same thing with Add column, Delete Row and Delete Column button click events.
However, now I added a Dropdown which when its index is changed needs to retrieve values from the database and create controls based on those values and then also bind the Db values.
But it doesn't work correctly since the asp.net page cycle cannot capture the dropdown's selected value in page_load as the page_load fired first and then the selectedindexchanged event is fired later, the controls are not created.
I don't know how to handle this scenario and incorporate it into my existing code.

I am Developing a database web applicationI am Creating web controls on page at runtime i.e in Page_Init event. No textbox are placed on .aspx page at design timeI have a datatable filled with a single record.now i want to bind a textbox (created at runtime) with a column of datatable so that when a page is loaded value in datatable's column is displayed in textbox.Other Important thing i want is when i make any changes in Textbox, It should be reflected automatically in a column to which textbox is binded. So while saving records i can save it directly from datatable. I dont want to write following tedious code before savinge.g.
DataRow mDr = Datatable.NewRow();
mDr["EmpId"] = TxtEmp.Text
mDr["EmpName"] = TxtEmpName.Text
Datatable.Rows.Add(mDr);

I have been tasked with producing a web application for a new client. What they're looking for requires a Gridview with slave Detailsview within an Update Panel.
I produced this, including the Gridview in markup, as follows:[Code]....
[Code]....
However, although it works, it's been requested that I move most of this to code behind (for easier maintenance), which is causing me a few headaches.
What is the correct option here, since I see many potential methods?
Should I create an instance of the Gridview and Update Panel in markup, then define all events and columns in code behind? Create a new Gridview entirely in code behind and place it within the Update Panel? Create both in code behind?

I think I've created and instantiated my first custom class. I'm pretty darn excited! Been reading up on it, I think I did it right but I'd like someone to double check. I'm trying to collect question ID's and associated answer values from a databound gridview and then insert them into the database.
I have two questions:
-Did I set up and instantiate the new class correctly? (also will need to access the class on other webpages)
-Am I ready for the next step of inserting into the Database with LINQ or is there something else I need to do?

If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

I am trying to create a table at runtime which is populated from information in a database. At the present time the table displays as follows: The problem is I need the "test test" text to be in the middle of the table, however if I show a box around the cell it only takes up the 1st half of the table regardless of the width I specify. Is it possible to have a dynamic table that effectively has rows where the cells are merged together in a specific way to allow the control to be positioned where I want it? THe code I am using to create the table is as follows:

where I am going wrong or is what I am trying to achieve not possible with a dynamic table?

I 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?
