VS 2008 Adding Columns To A Gridview Dynamically
Jul 13, 2010I have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?
I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.

Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.
Forms Data Controls :: Adding Dynamic Columns In An Existing Gridview?
Mar 2, 2011I have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.

Forms Data Controls :: Add Columns Dynamically In Gridview?
Jan 21, 2011I have gridview which auto generate column is false, and I add some template columns, databind with a class ClassA . it works fine. now, I need add some columns to this gridview. the problem is: I do not know the # of columns that will be added (it is dynamic), and the data with these columns is in ClassA, but it is a array (or list). so, there is no public property for these data, only the array.
now, what I did is: I dynamically add template column to the gridview (column header ...), so, it shows the correct columns in the gridview, but how can I bind the data? I found some example, i.e.
[URL]
but it is for aleady know the data field (which is a public property in the class). all I have is just a array, and I need bind them to the newly created columns in sequence.

Forms Data Controls :: Gridview With Links / How To Dynamically Add Linkbutton Columns From Code Behind
Jan 26, 2010I have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]
I need to display linkbuttons that link to user-id related documents in columns 2 to n for each name.How do I dynamically add linkbutton columns from code behind?
Forms Data Controls :: Dynamically Adding Second HeaderRow To GridView?
Mar 15, 2011I've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
[Code]....
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)

Forms Data Controls :: Get Cell Values In A GridView After Dynamically Adding Validation Controls?
Mar 31, 2010So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.

View 1 RepliesForms Data Controls ::working On Setting Up A Gridview That Dynamically Creates New "columns" After A Set Amount Of Rows?
Mar 10, 2011I'm working on setting up a Gridview that dynamically creates new "columns" after a set amount of rows. To do this, I bind a datasource to the Gridview and then add new cells and shift the other items into those cells. I seem to be having an error with the link buttons that I move around. All of the items get put in there correct location, but for some reason, when I click a link button that has been added to a new cell, the sender's text is the LinkButton in the original cell's text. Does anyone know why this would be happening? Is the gridview not meant to be manipulated after it has been data bound? This is the code that I use to update the gridview.

C# - Dynamically Adding Columns To A Table In An MVC View
Apr 20, 2010I am returning an IList to my model of data about users. I want my end users to be able to select which columns they want to see.
I know I can do this with a huge "if statement" however, I know there must be a better way. I have created an Enum with the column names. I feel if I could take the IListItem.EnumName I would be set. However, I'm not too sure on how to do this.

Forms Data Controls :: Adding Columns To Databound Datagrids?
Mar 5, 2010I have started creating a DAL and have successfully bound my adaptor and the query within the adaptor to a gridview.
In lots of the intranet type apps I code in regular ASP for myself I often have a few columns with little icons in that do various things for that rows identity, such as drill down to more details, overlay a graph, text the person via an ajax call, send em an email via ajax and so on.
I think Ive got the hang of styling elements of each row depending on the data but Im completely at a loss as how to add a column which would have an icon whos url link properties would be dependant on the data.
EG
ROW1 | Name | Email Address | ICONFOR EMAIL(with a querystring id matching the row id) | ICON FOR MORE DETAILS (with a querystring id matching the row id)
I realise I am probably looking at this the wrong way but its difficult when you are almost on autopilot doing these things in classic ASP.
