VS 2010 Binding Single Item Without Using FormView / DetailsView / Repeater
Aug 11, 2010
The title pretty much explains it. I want to bind a single item to a detail type control. I can bind to a repeater perfectly fine and obviously only one item will be displayed. It seems like there would be a better suited control for this. I know about FormView and DetailsView but they both generate a table which I don't really want. Something similar to the Repeater since it doesn't generate any content other than what you put in the template.
am in commercial development for few months only,the team leader is not using gridview, detailsview, formview, repeater, datalist.we alwyas write our own looping to dislpay the data even it is read only.He said : we do this for better performance.and I am always thinking, so why microsoft create them???I checked other questions and articles, and I am still confused.
I'm trying to bind both GridView and DetailsView to a single ObjectDataSource declaratively (in markup). I'm getting the error read as below when I tried to run it.
"The DataSourceID of 'DetailsView1' must be the ID of a control of type IDataSource. A control with ID 'ReservationsDataSource' could not be found."
It works when I bind GridView and DetailsView each seperately to my ObjectDataSource. Is it I can't bind two pagable data web controls to a single datasource?? or there is a trick needed to be done for this to work.
FYI, I'm trying to create a Master/DetailsView of my data. DetailsView of my application should show the record selected in GridView and it should be editable.
I am trying to use a repeater control that will display a hyperlink control. For the text of that Hyperlink control I would like to concatenate to fields from my data source (lets say First Name and Last Name). How would I do this appropriately for the Hyperlink control within an ItemTemplate?
I am trying something apart of my boundries, is there any way to disable a single intem in dropdownlist or stop the ddl change event for a single item.
What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
I wanna use the DetailsView control without binding it with a datasource (just in insert mode) but the problem is when I try to get the values of the fields throught ItemInserting event handler I found the e.Values property empty however there are some fields.
Note: I wanna use it (The DetailsView control) [instead of allign the fields manually] because there're already a theme for it in whole the system and I don't want to do that again from scratch for custom template.
I have a DetailsView control which gets data from a IEnumerable custom class. But I can't get updated values from the control so I can process to update them manually in the database. How can I do that?
I have a FormView that I user for updating a record. There is a link button that when fires should perforom the updating via BLL and DAL. I am not using built-in ODS and I will not condsider using it. I have all my grids and formviews populated manuualy by calling methods that fetch the data from the database. For instance my details view is populated like this:
protected void DlMembers_ItemCommand(object source, DataListCommandEventArgs e) { if (e.CommandName.ToString() == "Select") { DlMembers.Visible = false; lblError.Text = string.Empty; lblError.Visible = false; fvMemberDetail.Visible = true; fvMemberDetail.ChangeMode(FormViewMode.Edit); MemberBLL getMemberInfo = new MemberBLL(); int Ident = Convert.ToInt32(e.CommandArgument.ToString()); fvMemberDetail.DataSource = getMemberInfo.GetMemberByIdent(Ident); fvMemberDetail.DataBind(); } if (e.CommandName.ToString() == "DeleteSelected") { DlMembers.Visible = true; lblError.Text = string.Empty; lblError.Visible = false; fvMemberDetail.Visible = false; fvMemberDetail.ChangeMode(FormViewMode.ReadOnly); } What I want to do if to capature my linkbutton on click event and do this (except that the runtime never reaches this method): protected void MemberInfoUpdating(object sender, EventArgs e) { TextBox id = (TextBox)fvMemberDetail.FindControl("txtIdent"); if (id.Text != string.Empty || id.Text != "") { TextBox txtFN = (TextBox)fvMemberDetail.FindControl("txtFN"); TextBox txtLN = (TextBox)fvMemberDetail.FindControl("txtLN"); DropDownList ddlAddress = (DropDownList)fvMemberDetail.FindControl("ddlAddress"); TextBox txtEmail = (TextBox)fvMemberDetail.FindControl("txtEmail"); TextBox txtHPhone = (TextBox)fvMemberDetail.FindControl("txtHPhone"); TextBox txtWPhone = (TextBox)fvMemberDetail.FindControl("txtWPhone"); TextBox txtMPhone = (TextBox)fvMemberDetail.FindControl("txtMPhone"); DropDownList ddlPos = (DropDownList)fvMemberDetail.FindControl("ddlPos"); DropDownList ddlIsAdmin = (DropDownList)fvMemberDetail.FindControl("ddlIsAdmin"); bool blIsAdmin = false; if (ddlIsAdmin.SelectedValue == "True") blIsAdmin = true; TextBox txtComments = (TextBox)fvMemberDetail.FindControl("txtComments"); MemberBLL updateMemberInfo = new MemberBLL(); bool UpdateOK = updateMemberInfo.UpdateMemberByIdent( txtFN.Text, txtLN.Text, ddlAddress.SelectedValue, txtEmail.Text, txtHPhone.Text, txtWPhone.Text, txtMPhone.Text, blIsAdmin, txtComments.Text, Convert.ToInt32(ddlPos.SelectedValue), Convert.ToInt32(id.Text)); } else { //Display error - no user id cannot update record } }
Below is a line I have in my ItemTemplate of a FormView. The value in the table is null rather than true/false. Is there any way I can set the default for this to be false if it is null? Or can I do this in my stored procedure in the Select statement to return false if null?
I don't much care for the template rigmarole of the ASP.NET FormView web forms control. It seems the only way to access template defined controls is to 'capture' module level references to the wanted controls in the ItemCreated data binding event, for use in other tasks and event handlers. Ideally I would just like to be able to call set this.DataSource and call this.DataBind on a page, but only the latter is possible through inheritence, and doesn't achieve any of my normal data binding needs. What else is there besides the hairy, scary FormView control?
I have a Formview that is bound to an SQL database, and in its item template I have added an image button.
That image button on selection needs to postback a primary key Value (VoucherID) to be used in a second control on the same page. In VWD I can get it to post back but I can't get it to post back with the VoucherID parameter.
I can easily get it to send a querystring parameter, but I don't want to do it this way.
I need a complete code reference for Detailsview and Formview using the code only:OnRowCreatedOnRowEditingOnRowUpdatingOnRowDeletingOnRowCancelingEditOnPageIndexChanged OnPageIndexChanging OnSorting OnRowDataBound
I have a FormView which will bind values from the database using a ID parameter from queryString. In my database, I have a field named CategoryList which can store multiple CategoryID (From Category table) in CSV format (eg: "1,3,4,5"). I'm using SQLDataSource as my datasource.
So, I want to show the selected category in CheckBoxList. Meaning that, the checkbox will be checked (on page load) if its ID is in the CategoryList. Also, I want to allow the user to check/uncheck the CheckBoxList and updates to the database in CSV format. How can i do that?
