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.

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 ?

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# - 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.

Forms Data Controls :: Updating GridView With GridView Columns That Are Readonly

Feb 20, 2011

I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).

I have an UpdateCommand as follows

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>

The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.

I get the error "

Must declare the scalar variable "@PLAYERID"."

Programatically Change The HeaderText Of Gridview Columns In A Nested Gridview?

Jul 31, 2010

I have a gridview and I would like to be able to programatically change the HeaderText of it's columns (probably in the DataBinding event). I know this can normally be achieve with something like this:

myGrid.Columns[0].HeaderText = "My Header Text";

However, the gridview in question is actually nested within another gridview (via template column). So I can't access it directly. I'm trying to use the FindControl method to access it, but so far that isn't working.
