Forms Data Controls :: Display A Radio Button In The Editable Mode Of A Detailsview?
Jan 19, 2010
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#.
How would I go about coding a button that would set a DetailsView in the "New" mode? (all fields blank and preferably place the cursor in the first field to be entered). I have the Insert mode turned on in the DetailsView but want to add a button outside of the DetailsView that would do the same thing.
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
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 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:
Note: Code is taken from this tutorial [URL] I currently have an editable gridview with only some columns editable by the user. In the background I want to record the time/date they have saved the data to the grid. This column 'Time' is not bound to the grid. Is there anyway I can still include this update when rebinding the newly edited data?
I'm also having a problem saving the updated data of my column ActivityTotal. I've been debugging that and following the variable, and it holds the correct value, but just doesnt seem to update. I am providing the codes below for both my gridview and the cs behind and would be grateful if someone could take a look, I assume it's a sort of minor sql issue on my part.
code
protected void UpdateButton_Click(object sender, EventArgs e) { originalDataTable = (DataTable)ViewState["originalValuesDataTable"]; foreach (GridViewRow r in GridView_ABC.Rows) if (IsRowModified(r)) { GridView_ABC.UpdateRow(r.RowIndex, false); } // Rebind the Grid to repopulate the original values table. tableCopied = false; GridView_ABC.DataBind(); }
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 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 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 a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?
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?
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,
