Forms Data Controls :: How To Add Column To A GridView Programmatically
Nov 17, 2010
I have a GridView which pulls info from a SQL DB. It works fine. I use a CMS to upload the data which includes thenumber referred to below.
The last (rightmost) column in the GridView is a number.
I'd like to know how to know how to:
1) Make a further column visible (to the right of the number) which contains a Button BUT only when the user is logged in.
2) Make that Button call a function (the workings of the function are irrelevant here) and pass to that function the number in the previous column.
I know I could use a LoginView with two GridViews, one for logged in (showing the Button) and one for anonymous (without the Button), but then I'd have to put the Button in the database... I think.
A better idea would be to add the Button column programmatically.
how this can be done and how the Button in each row, when clicked, can pass whatever number is to its left as a parameter?
I've programatically created a DataView item by adding columns and rows to a table in the class file. Then I add that to my webform using a GridView. I'd like to hide some of the columns so that the end user doesn't see them but still be able to access their values.
How do I do this programatically? The table.Columns.Count returns the actually number of columns. Somehow when it converts into a DataView, it is only returning 1 column.
I have a gridview that has certain values in it that I would like to change based on a condition. For example, if a value in the column is 'x', I would like to make that Value Bold and have text that says 'Not applicable'
How can I do this? How can I programtically chnage values in a gridview?
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
I am using GridView ,I want to do a validation like if i edit any one of the Cell in that column, it will through the validation when the sum of column value is more than 100. How can i do this validation?
I need to change padding for one column in ASP.NET GridView, while all other CSS atributes defined in external CSS file should be left untouched. How can I do it? Update: Below is my code that solved the problem:
I have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.

How can I programatically call a gridview row when it is loaded based on the primary key. For example, say I have a record in the gridview where the column name is ID (Identity Field) and has the number 37 in it. When the gridview loads up, I need to get the rowindex where the primary key = 37 and have that row automatically selected.
I have already google the question, but couldn't found any relevant post.1) I want to make gridview's one column () editable according to some boolean value (flag). If flag is true when the edit is clicked, related column would be editable (text field), otherwise related column would be label.2) Same again, I want to make enable delete button in some rows and not some rows according to that flag.
I was wondering what would be the best pratice to databind a gridview programmatically.Normally i put my databind code in the page_load() but is there a way to reduce the number of times the databind method is called?I mean... the page_load() method seem to be called a lots of times when doing callbacks with the grid.
I have a gridview with bound fields and a templateField that receives data from a submit button which, depending upon the selected object, i.e. dropdown 1, 2, or 3, return a result set. The gridview also has a checkbox column which is used as a marker to determinie the rows to be added to and existing table. If a user selects multiple row, those rows are written to the database. Everything works.
Now, I need to add additional functionality to the gridview:
Upon selecting the checkbox, programmatically the accompanying row must become editable; for each row presented.
Deselected the checkbox, return the gridview row to a read-only state.
There are 14 columns, one of which is a dropdown which needs to maintain its default value.
