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 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!
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
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:
[Code]....
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 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.
I want to hide few columns of a gridview before they gets displayed. I want to do it by create a common function which can be used by multiple controls. I am using an extension and would like to know how it can be done.
Here is my code
[Code]...
I want to create an extension to hide or show columns provided in the list as an array. 1st function is used on page. While below two functions are needs to be used for multiple applications
I'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.
I have a DetailsView control with two columns and 7 rows. I need the two columns to merge in row two and get rid of the header. I only the data from the DB to display no the header name in row two. How do I merge it in DetailsView control?
I am displaying the output of a LINQ query in a Detailsview control. I have a Detailsview called DetailsCaAb and a DropDownList called DropDownList2, when the use makes a selection from DropDownList2 the Linq query fetches the data CatAbstract from the table CatagoryTables. e.g.
[code]....
Unfortunately I cannot seem to control what is displayed by the DetailsView, I only want to display CatAbstract, but the details view generates another column called Items. How do I ensure only the data I want is displayed? I need a way of controlling the columns generated programmatically.
I have a Gridview and I want to hide a column when empty. The code works then the column is in Boundfield but not in Templatefield. Can anyone show me the code of how to do it in Templatefield?
Is there any way to hide or show the columns in rdlc local report . I have main report with many columns now i have to hide or show some columns for creating the other reports from the main report.
I have a gridview containing 10 columns. Three of them are set to visible="false' by default. When I click on 'Export to excel' Button, I can hide those invisible columns.
[Code]....
There must be more efficient way than this. How can I find the invisible columns and store their information in array and then only do a loop once?
I have a gridview that I am loading from a stored procedure. I need to be able to hide certain columns and change the column names. Since it is loading with stored procedure the columns aren't listed in the gridview->edit columns properties.
