How do I set the value of a field in a detailsview to the selectedvalue of a gridview on the same page? I am also trying to set today date as value of another field in the detailsview as well as UserID. I wrote the following codebehind for the date setting:
TextBox tb = (TextBox)DetailsView2.FindControl("TextBoxCreDate"); tb.Text=System.DateTime.Now.ToShortDateString(); TextBoxCreDate is a template field in my DetailsView.
Unfortunately, I get a Object reference not set to an instance of an object. Error message.
I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event: Dim dv As TextBox = CType(DetailsView1.FindControl("txtNew"), TextBox) If (e.NewMode = DetailsViewMode.Insert) Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
I have a gridview and detailsview that are connected. When I delete records everything works fine except when I delete the last record in the gridview. I want the detailsview to revert to insert mode when I delete the last row in the gridview. Instead the detailsview shows up blank. I want to show the detailsview in insert mode after last row in grid has been deleted? How can do I this?
A DetailsView in Insert mode has all fields cleared after events such as the following:
1. Clicking New. 2. Clicking Cancel. 3. Clicking Insert (if the default mode is Insert).
I have some fields linked to ViewState and they are populatd at PreRender event handler. I am wondring if there is a single place where all relevant ViewState elements can be cleared instead of doing this in all possible relevant handlers such as ItemCreated, ItemCanceled, ItemInserted, etc.
I have some ImageField in my DetailsView and when I changed it to Insert mode then ImageField is also became the textbox that allow you to type something, and my question is how I can make ImageField to be read only when I changed DetailsView to Insert mode?
On my DetailsView for inserting, I have a field "manager code". When the user types in the code, I want another field "manager name" to be populated based on a lookup table in the database. I have done this on a FormView using code behind and "ontextchanged". How can I do this in DetailsView?
I use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?
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 using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:
ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.
The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.
In my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.
I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.
I have a problem with DetailsView linked with Database, DetailsView is Insert/Edit enabled, and adding/ediditng data works, however........ when I add a new record (DetailsView in Insert mode) and press INSET instead going to record I have just created in Read-Only Mode it shows me blank form, it looks that the "linking" field is null.
For ASP.NET, I'm using a DetailsView for insert and edit of a record. For edit mode I don't want to display the primary key field because it should not be changed. For insert mode, I want to display the primary key field because it doesn't exist and the user can specify it via a DropDownList that insures they will pick an unique value. A TemplateField is used in the DetailsView markup for the primary key field (hence the DropDownList for insert mode).
My problem is that I cannot get the primary key field to not display for edit mode and to display for insert mode. In the markup I have:
With the TemplateField Visible="True", the HeaderText="name" always displays which I don't want for edit mode. With the TemplateField Visible="False", the field never displays which I don't want for insert mode.How can I achieve the display behavior I want for insert verses edit mode. I'm fine with changing some property programmatically rather than relying an a pure markup approach,
I am trying to "reset" the DetailsView in View1 to ReadOnly mode if the user changes the index in RadioButtonList. Currently, it is working correctly for the first pass and second pass, but fails at the third pass. I want it to just cycle through the DetailsVIewdatabound event, but the cycle breaks on the third pass and I'm not sure why?
I am trying to handle the detailsview programmatically but I don't know what I am doing wrong. My details view control isn't going into edit mode. My code for my gridview's select button properly loads the data into the detailsview but once the detailsview renders clicking on "Edit" doesn't switch the detailsview contol into edit mode.
This code draws the information from my database and loads the information into the dataview:
[Code]....
This code is in my dvTeamDetails_ItemCommand sub and the beep works:
I currently have a page that is used to insert or update records in a DetailsView using an EntityDataSource control. Insert is working perfectly. However, Updating is not. I have the default view set to insert. In PageLoad, I have:
[Code]....
However, the DetailsView always defaults to the first record in the table rather than the record with ID that is equal to the ID querystring parameter. I am not sure how to make it select the correct record. From spending a while researching, it looks like I might need to use a QueryExtender control on the Entity DataSource, but haven't been able to figure out how to configure the QueryExtender correctly.
There is also perhaps some sort of datasource="stuff", databind() that I could toss in there but again.. not really sure how to proceed.
I have a SQL DB with just 2 fields, ID and TEXT.What i was trying to do, was placing a Detailsview in EDIT MODE, then selecting from the DB like SELEC TOP 1 Text FROM DB.Then i placed a Ajax HTML Editor in the template field.How can i, keep the HTML Editor on the page, and use it for INSERT and/OR EDITING ?e.g.: on the first time the user opens the site management page, it will be blank, so it will show the HTML with no text on it. but the bottom button will be UPDATE and CANCEL. So when he enters the TEXT he clicks on UPDATE.
I'm really struggling with this. How do I display my data with radio buttons in a detail view and bind it to my datasource like I've done with the textbox? The database values are int {yes = 1, no = 0, na = -1}. I want my user to be able to quickly update the radiobuttons instead.I'm working in C#.
