Show Several Columns In Datasource As Autogenerate Columns In Gridview?

Jan 27, 2011

I have a datasource, which includes many columns, idealy, I need use a gridview to show:

1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.

2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?

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.

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.

How To Make The Gridview Columns NOT To Expand And If The Data Needs To Show In Full

Feb 25, 2011

So i'm currently designing a site ( ) and i've made my skeleton master page.What i've noticed is that the gridview must be cut down a little to fit my 1024x768 design.

Now i have taken a note in the past to look at this but i couldn't find the time so i guess the time is now.
What i have problem with is shrinking the columns.If i have a name, say "jack R" and i make a gridview column,say width 15 then the name is included and all is ok.However if i have another name,say "jack the 3rd" then the column will expand to fill the name.So all the grid will expand to the right.I have tried in the past some stuff but it seems that if a value is longer than the column then i expands whatever i do.Also i was surprised to see that only the dates will not expand and go "down" instead of right.At least in the gridview i have.

So the 2 questions.How do i make the gridview columns NOT to expand and if the data needs to show in full then how do i make the data go DOWN and not expand right.I have no problem of the grid expanding downwards but i have a problem of the grid expanding to the right.

Forms Data Controls :: Hide / Show Gridview Columns Using Javascript?

Jul 15, 2010

I have a webpage that lists information about trucks and their map sections and whether the combination is active and will be used.

On the page I put a check box that says Show Only Active and marked the checked property as true by default. When the RowDataBound event fires I check to see if that checkbox is marked as true and if it is I check if the individual map sections are marked as active. If they are not active then I set the row visibility equal to false like below.

Forms Data Controls :: GridView,calculate Value Based On Other Columns& Save To Datasource?

Nov 8, 2010

I had just started with Visual Studio 2008 + VB.net. I've now designed my tables, and basic gridview functions properly.Now I'm faced with the problem of having to calculate a value based on 2 - 3 columns/data in the gridview, display the result in an existing column in the same gridview, and saving the calculated value in the datasource.I had initially created the "Total" column as a textbox displaying a manually calculated amount that is saved in the datasource. Now, I want to change the field to auto-calculate based on 2 other columns.

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".

Is there some way other then keeping track of the # of columns in the table manually for me to set the colspan to be # of all the columns in the table-1? Preferably a HTML or CSS solution?
