I've got this gridview. The gridview uses TemplateFields as the number of fields in the database's table. What I do next is use an ItemTemplate to present the correct column info.
Now, problems rise when the user click's Edit. Since I can only use EditItemTemplate to edit I am resulted with a control in each column. What I really want is to have a single row with no columns so I can easily style the edit mode (having a table with a different layout for example).
Is this possible? If so, how?
I suspect you will have to create your own specialized class that inherits from GridView and does its own rendering to accomplish this.
You might hack some workaround though... such as manually editing the rendered HTML output or DOM.

Which control should I use to show post records from my database in ASP.NET?
On my project page I would like to show recently featured projects. The number of projects can vary. I'm looking for a control like GridView or something that alter the properties of accordingly to get data from my database.
Below is an image of what I would like my page to look like:
I have been told to use asp:ListView but I don't know how to use it. Is this the right solution for my problem?
You could use a GridView Class
Displays the values of a data source in a table where each column
represents a field and each row represents a record. The GridView
control enables you to select, sort, and edit these items.
Or a Repeater Class
A data-bound list control that allows custom layout by repeating a
specified template for each item displayed in the list.
Specifically, I am using DevExpress 10.1 for their APSxGridView. I have a grid with a command column. I plan on using two of the standards: new and edit. I would like to create a custom button that will take a value from within the current row and redirect to another page using that value as part of the query string.
I have seen some suggestions to create a hyperlink column to do this, but I would like to have all of these commands in a single column. I can see solutions for this if I weren't constrained by leaving all buttons within a single column. Is this something that maybe I could assign during HtmlDataCellPrepared?
Thanks.
If it's anything like the standard .net GridView I would create a template field. In a template field you can put whatever you want in there. I have done this when I need an asp.net control (a button, hyperlink, etc) instead of the standard grid buttons and commands. You can then access controls and the datasource during the OnRowDataBound event handler and customize the button during run time if need be.
I have an "action" column in my repeater which shows actions a user can select for an item. The column contains ASP.NET HyperLink or LinkButton controls. Some actions are based on whether a user is in a role, which I determine programatically. I'm struggling with the best way to dynamically generate this column when I populate the repeater. Now I am assigning in-line code to the Visible property of each control, but I feel that is sloppy and not very straight forward. Would I be better served using a PlaceHolder control and populating that at runtime? What kind of methods do other people use for situations such as this?
The "normal" way to apply any sort of dynamic rendering to a Template based control such as the Repeater is to handle the ItemCreated or ItemDataBound events.
In your particular case, you could check appropriate conditions within that event handler and toggle the visibility of the relevant "Action" column.
Also, see this question where Ian Quigley posted a code snippet that should serve as a good example for you. It may also help to read my own answer which shows how to use visibility toggling in inline code.
I have created a GridView whose columns are dynamically created based on my data source. I have implemented these columns by using the approach described here.Those columns display properly on the initial load. However, I need to implement commanding so that a user can edit / delete a row in the GridView.
At this point, I have implemented commanding as I would with a normal GridView. I have a TemplateField with an ItemTemplate that has LinkButton elements for edit and delete. The CommandName for each LinkButton is set to either Edit or Delete respectively.
Oddly, when a user clicks either the Edit or Delete link, the data in the GridView disappears. However, I have verified that I am in fact re-binding the data when one of these LinkButton elements is selected.
Can anyone provide some suggestions as to what the cause could be?
Thank you!
Here are good examples. You can figure out postback issue.

I have a Gridview in which no rows populated initially. means i am not setting any datasource to gridview.I have to populate gridview by adding footerrow.I have given visibility of footerrow as true.So one error is coming as 'Object not set to an instance of an object'.what may be the reason for this? Can anybody help?
Actually i need to add data into the Gridview through the FooterRow.After inserting a few records,i need to insert this data into the database.So, i want this Gridview only to insert data into the database.For a particular "FileID", i have many records,thats why i am using Gridview.Is there any other method for this?
See this question: How to insert a Row in GridView.
The object reference error is probably because you have set no datasource for the GridView. In such cases, the Gridview will not render.
Edit:
I have already linked to another question which provides a very useful link to accomplish the type of functionality you desire. Since you appear not to have found it, here is the relevant link - How to easily insert row in GridView with SqlDataSource?
The article shows how you can use the EmptyDataTemplate of the GridView to enable record insertion using a GridView. Note that you will have to modify the logic a little to insert a group of records in one go, rather than one at a time.
If you have a problem with this solution, please clarify via comments.
