I am dynamically loading user controls into my main page on button event.The user control has a textbox and a gridview When i enter data in textbox , the autopostback event fires and loads data into the gridview. when i load another instance of user control and do any post back the gridview data is not persisting.Until and unless I bind the data, gridview is not having any data after postback.This is creating issue when I al updating a row in gridview as data is not persisting after postback.

I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

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 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?

Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .

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.
