C# - Collapsing Columns In Gridview?
Aug 9, 2010Instead of hide/collapse the traditional rows, what I want to do is a user control that hide and collapse the columns when I click in the respective buttons.

C# - GridView - Columns.Insert() Cause Data To Vanish On Postback But Columns.Add() Works OK?
Oct 13, 2010I 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.

View 1 RepliesHide Columns In GridView With Auto - Generated Columns?
Jan 19, 2010GridView1.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, 2011I 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, 2010I 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.

AJAX :: Accordion Immediately Collapsing On Safari?
Nov 3, 2010I have a relatively simple AJAX accordion control running on a C# website. It works perfectly on Firefox, Chrome, IE, but not on Safari. On the iPad and iPhone, the accordian expands, but then almost immediately collapses again. It is supposed to stay open (and does so on the other browsers). After expanding, the page looks like it is refreshing (I can see the bar at the top).I have other Ajax controls on the page that all seem to work fine. I have not put in any other code to expand or collapse the accordion control. This page uses a masterpage, if at all relevant.Here's what the properties look like up to the start of the panes:
<AjaxToolkit:Accordion ID="AccordionStat" runat="server" SelectedIndex="-1" RequireOpenedPane="false"

Web Forms :: Panel Not Collapsing On Page Load?
Apr 27, 2016I am working on an asp.net webforms application using VS2013.
I have two panels on a form. The first panel acts as intended, it is collapsed when the page loads. But the second panel is not collapsed when the page loads. Instead it collapses after I do anything else on the form like choosing a dropdown list or gridview - neither of which are located in the panel I am attempting to collapse.
The following is the code for the first panel that is operating correctly:
<asp:Button ID="btn_open_new_rvw_frm" runat="server" Text="Initiate A New Document Review" CssClass="frm_btn_style" Visible="false" /><br /><br />

AJAX :: To Make Expanding/collapsing CollapsiblePanelExtender From Code Behind Smooth And Animated
Aug 24, 2010I've got a CollapsiblePanelExtender in place on a panel in test and it works like a champ. (I get excited about the simplest things). When I click the panel header it expands and collapses with smooth animation, as expected and desired.
But when I change its state via code behind, it seems I am merely changing its state and somehow bypassing the javascript that controls the smooth animation.
My markup is out of the box. I have added code behind and some javascript, but I am missing the connection. Here is the javascript:
function pageLoad(sender, args)
{
smoothAnimation();[code]....
And here is the code behind:
protected void btnExpand_Click(object sender, EventArgs e)
{
this.CollapsiblePanelExtender1.Collapsed = false;[code]....

Forms Data Controls :: Updating GridView With GridView Columns That Are Readonly
Feb 20, 2011I 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, 2010I 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.

Mar 17, 2011I have the asp.net application where I am having the editable grid view with the edit,Delete,Add options. this grid having as usual Template fields . I want to hide some columns. I know i can do that by using columns index. but i don't want to follow it. instead I want to hide columns by Id. this is because if in my application further I need to add more columns then there is need to change the code gain and again in the core. so I am choosing this way. Bu as i found <asp:TemplateField /> does not contain Id attribute. so it is become impossible for me to hide <asp:TemplateField/> by Id.
View 3 RepliesC# - Getting Xml Columns From LinqDataSource To Appear In A GridView?
Jul 25, 2010I have a LinqDataSource and a GridView displaying a table. Columns of type xml don't show up. I'd like them to show up something like they do in Sql Server query outputs, with a link to display the clickable xml, though there may be another approach i'm not considering (maybe a styled display of the xml data, etc.). Two things i'd like to know how to do
First, get the xml converted to a string, and display it in the table. Maybe the first 30 chars.
Finally, style the xml into something useful, like a clickable link to display the full xml, or a sub-table, or a styled string.
So the following works, and displays a nice table, with edit and delete links. But Xml fields are missing. How would you go about adding support for the Xml fields?
