C# - GridView - Columns.Insert() Cause Data To Vanish On Postback But Columns.Add() Works OK?

Oct 13, 2010

I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"

protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}

I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.

Forms Data Controls :: Create An ASP Grid With Dynamic Columns With An Ability To Freeze Columns And Rows

Sep 20, 2010

I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

Entity Framework: Substituting Primary Columns For Foreign Key Columns

Jun 30, 2010

I've created a new ASP.NET website. I've generated an Entity Data Model from my database and have dropped a entitydatasource and gridview onto my page and wired up the gridview to pull from the entitydatasource. Now I get columns like this: id extension prefix did_flag len ten_id restriction_class_id sfc_id name_display building_id floor room phone_id department_id

In each case where the item is named something_id this reflects a foreign key relationship in the database - and I did choose to have the EDM expose foreign key relationships. I'd like to make it so the gridview pulls in the values for these foreign keys rather than just showing the ID numbers - so, for example, department_id might have a value of "101" right now but it should pull from the department table "Marketing".

Hide Columns In GridView With Auto - Generated Columns?

Jan 19, 2010

GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();

But Grid is ok I can do

for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)

I rename request headers here but

GridView1.Columns[i].Visible = false;

I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?

C# - Display GridView With Many Columns As Two Sets Of Columns?

Jan 20, 2010

I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.

So instead of this:

Column1 Column2 Column3 Column4 Column5 Column6
Data Data Data Data Data Data
Data Data Data Data Data Data
Data Data Data Data Data Data

I'd like something like this:

Column1 Column2 Column3
Data Data Data
Data Data Data
Data Data Data

Column4 Column5 Column6
Data Data Data
Data Data Data
Data Data Data

As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.

C# - Load A Type In Parent-child Website?

I am developing a C# VS 2008 / SQL Server 2008 website. Although this same code compiles in the Project version, the website version does not compile. Many of their files are the same so I do not understand even where to look. The only compile error I get is:

Lay Out 4 Columns Of Controls In CSS?

Feb 1, 2010

Anybody have any links to any good references for laying out ASP.NET controls in CSS? For the life of me positioning in CSS doesn't make sense to me. I am basically trying to lay out 4 columns of controls: Label, TextBox/DDL, Label, TextBox/DDL. I thought I could just do .col2, .col3 and .col4 CssClasses with {Position:absolute; Left:150} type language in them, but when I get to the second row of controls, they overlap the first row a bit.
