I have the asp.net application where I am having the editable grid view with the edit,Delete,Add options. this grid having as usual Template fields . I want to hide some columns. I know i can do that by using columns index. but i don't want to follow it. instead I want to hide columns by Id. this is because if in my application further I need to add more columns then there is need to change the code gain and again in the core. so I am choosing this way. Bu as i found <asp:TemplateField /> does not contain Id attribute. so it is become impossible for me to hide <asp:TemplateField/> by Id. any remedy for this ?
You can always do it using column header text. Run a loop through columns of the grid view and compare header text of the column with the constant declared and hide the column, this way, if you are adding any number of columns before or after the column will not affect the code.
Maybe create a div with an id inside a template field and hide that div with client code.
Perhaps just have a different grid markup for each "view" you want to show to the user, so one grid with all the columns, and another with limited columns.
I am assuming you would always be binding the same data to the grid (regardless of whether you are hiding/showing columns), so then you would just need some logic in your code to determine what "view" you want to show the user (i.e. what grid you want to bind to).

I need to make a table with huge data from a database, I've done it very easy with a gridview in asp.net but there is a big problem,I need to customize that table a lot.
I want something like this, with a row with data about a person and the row after with a description of projects he's in, then another row with another person data and so on.
Table:

And when i click/hover on a platform(platform i want to be a accordion propriety/it can be a button too) to display a table in the right or down side.
Table inside the platform's accordion:
Hope you get the idea guys, how can I do this with horizontal table lines, tables in accordions click/hover and databind? I need to take data from database and put it in the tables I described but I don't know if i can do that with asp.net gridviews which automatically generate the rows/columns it needs or is it another method ?
Any idea, advice, code is welcome, thanks!
A GridView is a simple "PowerPoint" solution for simple data models.
If you want more complex things get rid of the GridView and use a Repeater to create your HTML table instead. The Repeater control lets you create the table row tags in the ItemTemplate. You can easily generate two rows for each item in DataSource.
Of course, you need to generate the table cells (columns) manually as well with the Repeater control. Use Literal or Label controls to view the data in the table cells. Use
<%#: DataBinder.Eval(Container.DataItem, "propertyname") %>
to assign the Text properties of the controls.
I am new to Asp.net and C#.I am working in a project where I need to create GridView.Now I wanted to bind this column wise with the data.Like the column1 in the grid is "Category" in the table of database and so on. I also want to create the Hyperlink on the basis of the content in database for example I want to show the text of Hyperlink as "This is Java program" and URL specifies as "http://blogs.article?id=1".Please tell me that how I can do that.Currently I am able to bind the all three columns in the table to the three columns in the grid.
Take a look at the HyperLinkField class. This should provide exactly what you're looking for.

I want to add DomainUpDown control inside a DataGridView as a separate column. Each time a new row is added, I want that DomainUpDown control also be added. I also want to know when the user click the DomainUp or DomainDown button in DomainUpDown control for each row. Is it possible or not? I am using language vb.net/C#. I want to do this in winform not in ASP. Any help or suggestion please!!!
All you need to do/know is how to add an unbound column to an already data bound DataGridView, because from your description you are trying to add a column to a grid which already contains other data bound columns. In fact it would be easier if you had such column in the DataTable, also because with unbound columns you need to make a slightly bigger effort to populate and save the data from/to somewhere.
anyway it should be possible, MSDN explains it here: How to: Add an Unbound Column to a Data-Bound Windows Forms DataGridView Control
i need to display the list one by one in the same line.
It mean instead of binding the value in the row i need bind it in new column first row value. Is that any control available to view the item horizontally .
i have my data in data table.
I'm not sure if I understand your question correctly but I think what you want to use is a repeater. This way you can use whatever markup you want in the itemtemplate to determine what the layout of your data is when it is displayed to the user. You could do something as simple as <%#Eval("WhatEver")%> and you would get horizontally repeating values of the WhatEver column.
I have been given a mockup that I do not know is possible to code in ASP.NET without being a real html and javascript wizard.
I want a GridView that when a row is selected, the selected row expands and below the selected row a panel of additional information is shown, which would also include another small GridView. The idea is this would all be in-line. So if the user selected row 4, then the additional information would appear below row 4 and then after the additional information the parent GridView would continue with row 5.
Ultimately I would want to do a multi-select type of set up, but first I need to figure out if this is even possible. Also, the solution must be 508 Compliant
The one solution I considered was using only one "column". Then I would put all my fields in the ItemTemplate, and my detail panel content in the EditItemTemplate and instead of selecting the row, set it to edit mode. The problem with this solution is I lose the functionality of multiple columns if I throw everything in one huge ItemTemplate.
Any and all suggestions or ideas are appreciated.
What you're describing would be best fulfilled with a ListView control. It takes a little more templating work to set up than a grid view, but you have much more control over it and you can emulate the look of a GridView. You would set your Selected Item template to contain another ListView (or GridView) thats bound to your detailed data.
I've done this using a gridview inside a ListView and using ajaxcontroltoolkit collapsible panel
Your parent list would be a listview that would have 2 table rows for each item, on the first row your parent column, on the second row use colspan and add a gridview wrapped on a collapsible panel
