I have a DetailsView control, in edit mode, I want to hide and show fields based on a DropDownList's value inside it (the DropDownList makes a postback).
The problem is that when a hide and the show operation is maked, the DetailsView control will make a rebind for it and all the filled fields are cleared!
How can I prevent this behaviour?
Suppose I have a DetailsView, which is bound to a SQLDataSource. The underlying table has two columns, an ID and a value. When in display mode, I want to display only the value. When I switch the DetailsView to edit mode, I want the user to edit the value, and not see or edit the ID. Making the ID column not visible solves this, EXCEPT that then the ID value is not stored in the DetailsView so two-way binding does not work, and I can't update the corresponding DB record. How do I do two-way data binding with a DetailsView, but hide the ID column from the user?

I have a dropdownlist, the contnet in the gridview (sqldatasource connection) changes based on the value the user slects, say I have play1, play2 from the dropdownlist, I would like to show column1, column2 and column3 with user selects play1; show column4, column5, and clomn6 when use selects play2; the datatable actually includes all 6 columns.
I understand that I need to use something like RowCreated event, and I need to set up condition based on the dropdownlist value, but I dont really know how to.
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.
[code]....
dv = new DataView(table);
Table.Columns.Add("ID", typeof(string));
table.Columns.Add("Type", typeof(string));
table.Columns.Add("EmpName", typeof(string));
table.Columns.Add("Manager", typeof(string));
row = table.Rows.Add();
row["ID"] = result["ID"].ToString();
row["Type"] = result["Type"].ToString();
row["EmpName"] = result["EmpName"].ToString();
row["Manager"] = result["Manager"].ToString();
Then I am adding boundfield to gridview for all 4 columns. Now I want to check if "Type" column contain "Sales" thne do not show "Manager" columns. Let me know can I do this?

I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?
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?
I am using a detailsview to show a record from the database for editing - or for inserting a new record. When a checkbox in one of the fields is changed by the user I want to hide another field. To avoid unnecessary postbacks I want to use javascript. Here is a simplified version of what I have so far:

I have been able to select the "txtPromoCode" textbox and hide it, but it leaves the headertext. I want to hide the whole field.
I asked something like this before, On the detailsview I need to perform an IF THEN and hide fields based on their value.
View 5 RepliesI need to be able to convert all input fields in a DetailsView (Insert) to uppercase. How do I do this? My SQL query and the whole insert statement takes place in ASP.NET, and not in code behind so I'm not sure if I can dynamically do this in ASP.
I've used Text-Transform in CSS to make them look uppercase for the user, but it still enters the details in lower case in the field.
I 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 RepliesI have a GridView bound to a DataTable that I construct. Most columns in the table contain the raw HTML for a hypelinklink, and I would like that HTML to render as a link in the browser, but the GridView is automatically encoding the HTML, so it renders as markup.
How can I avoid this without explicitly adding HyperLink, or any other, columns?

View 4 RepliesI've got a grid view on my form that is bound to a data table at run tim. The data table is returned by a function rather than direct from the DB so I can't set the datasource at runtime.
I bind the grid in the page_load event like this:-
Code:
Dim _dt As System.Data.DataTable
_dt = _srvc.GetVinylShutters(0)
_dt.Rows.Add(_dt.NewRow)
grdShutters.DataSource = _dt
grdShutters.DataBind()
(_dt.Rows.Add(_dt.NewRow) is just there to add a blank row in, otherwise I wasn't seeing any columns at all)
I've then got the following snippet which I want to use to hide some underlying columns:-
Code:
For Each col As DataControlField In grdShutters.Columns
Select Case col.HeaderText
Case "OrderID", _
"ShutterID", _
"ModelID", _
[Code] ...
The thing is, wherever I put this it doesn't seem to hide the columns. If I break into the code I can see that grdShutters.Columns.Count equals zero althought I can see that the bound datatable has 38 columns.
I've tried the Page's Load, LoadComplete and PreRenderComplete events as well as the gridview's DataBound, RowDataBound and RowCreated events. I get teh same result in all of them. The grid doesn't actually have any columns until it appears on the screen.
