MVC generates the following code in my edit view for me but I don't want the user to see it, let alone try and change it. If I delete the code I get an error because a required value is missing. What is best practice when dealing with this?
How I can get the generated view code below to place the editor-field to the right of the editor-label, on the same row? I don't want to mess with the generated defaults, e.g. remove the divs, as I am still in very early dev and regenerate views quite often.
I have searched far and wide and discovered that if you hide gridview colums in the Gridview's databound event, as per the code below,then the objectdatasource binds multiple times according to the number of columns you are hiding. This is definitely the case.
I have a user requirement to hav the ability to directly edit the gridview without having to click the edit link. I was thinking of showing dropdown lists for each column-to-row so that the user can select the values for each record. Then the table will be updated accordingly (no update link).
Is this possible or do I still need the edit template and specify the item template with the dropdown list?
I have a page where I have a tab container and four tabs. the problem is on the first tab "manage quote request" I have a Gridview with the quote request general informatin listed and have a template field created with a link button to databind to the formview quote details. the porblem comes in when after I click on the select linkbutton. the Formview loads right. Then Whe I try to click on the edit linkbuttin in the form view I have to click it twice to change the mode to edit.
I am using a telerik radgrid so there are around 5 columns each column edittemplate contains a control along with a required field validator and also a property called AllowMultiRowEdit is set to true so i am able to multiple rows in edit mode.
If any of the values are cleared the for multiple rows I want only those to be validated on update of that particular row.
So i implemented the Grids item data bound event find each and every validator along with the update button and set a unique validation group.
The above implementation most times but fails at some time. Is there any other way of going about this ?
Shouldn't ScaffoldColumn(false) hide the field in the view? I create a strongly typed CREATE view (AddSO), expecting that the soID column won't be rendered and that the Label name of the field 'name' will be 'Full Name'. But the AddSO view renders the soID column and still labels the 'Name' field as 'Name. What am I doing wrong?
Is it possible to make the tree in a "collapsed" state where all the Leaf nodes and ONLY leaf nodes are hidden from view until its parent node is expanded? The ideal solution would be to do this without a postback, but any solution at this time would be helpful. The "collapsed" view would look like this:
Root |-Parent |--Child |--Child
Expanding the Root, Parent or Child nodes should show their Leaf nodes. Collapsing the node should re-hide its leaf nodes, but leave the child nodes visible.
My project includes a grid view which displays information of inventory items (Assets), data is quried from AssetTable. The GridView has a command field to allow editing, below is a description of the tables and how data is displayed
Tables BuildingTable: (BuildingID, BuildingName) AssetTable: (BuildingID,..,....,....) ItemTemplate: Using a LINQ query I join the two table and displays in a label control a string which includes BuildingID and BuildingName (5 North Building)
i just want simple mechanism to make images update at my website copyright protected, so i want to protect them witht the password. any of the techinque will do , i just want the iamges to be password protected so that i can dignose whether the uploaded image is not from my site.
I have 3 edit template fields in the gridview with 1st and 3rd as a textbox and second one is a dropdownlist. The second one gets it's data from another table. I'm trying to get the values in the 2nd one and I'm unable to do it.
im using gridview to read data from datasuorce(my access) and im editing data using 'enable editing' from smart tag(in design window .aspx), now i want to change the edit text: edit(i hav named it as edit) to 'view' for one particular user whose name:'sunil'?
this is my table(in my access layer and calling this data through datasource of gridview):
I have a combobox that is used as a control for Formview, so when the user selects a name from the combobox the data in formview displays in edit mode. However, some if the data that is displayed in formview needs to be empty. For example if the Date is being pulled in, it needs to be empty or null in edit mode.
I am facing a situation where I have to disable GridView field (in EDIT mode ) conditionally.
Here is the situation,GridView has 5 fields "Product Name" "Small" " Medium" "Large" "XLarge"
Here is the problem, application has section where user activate/deactivate sizes (SMALL,MEDIUM,LARGE,XLARGE). Suppose User activates "SMALL" and "LARGE". Now When the GridView is populted normally, I don't have to disable any fields. But when the user clicks "EDIT" on GridView row, I want "MEDIUM" and "XLARGE" fields to appear as disable.
Here is what I know
1) I will have active sizes in SESSION ... in the above case (SMALL and LARGE)
2 I know I have to catch GridView_RowDataBound and then I have to check for the edit mode for the row.
i have a grid view with some coulmns like Name,Phone no etc with Edit,Delete column in grid view. I click a row in grid view to Edit,it goes another page where i can edit all fields .Once i update i redirect the page to gridview. I want the grid view to remain in that particular page say 4 of the grid view
I'm creating a confirm delete like popup with an iframe to use along with a gridview. When you click delete on a gridview row, the iframe shows up and asks if you would like to delete the associated image as well from the server. It works perfectly the first time I delete a row. After that whenever I click select or edit on a new row, it calls the rowdeleting event from the last deleted entry every time. I'm stumped.Here's the Sub:
'// Event that Occurs when the Delete Button is Clicked //' Protected Sub Confirm_Delete(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting Dim file_name As Array = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "/") If file_name.getLength(0) = 1 Then file_name = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "") End If Dim fn As String = file_name(file_name.getLength(0) -1) fn = replace(fn, ",", "%2C") fn = replace(fn, " ", "%20") Dim url As String = Me.Master.get_root_url & "CrimeBulletinProject/ConfirmDelete.asp?img_list=" & fn & "~!" confirm_delete_frame.Attributes.Add("src", url) confirm_delete_frame.Attributes.Add("style", "display: block; left: 50%") End Sub
I created a project template at my work place that includes several classes. These classes will never be used in any view.Is there any way to hide these certain classes from the Model class combobox when you go add a new view?
By picking MVC for developing our new site, I find myself in the midst of "best practices" being developed around me in apparent real time. Two weeks ago, NerdDinner was my guide but with the development of MVC 2, even it seems outdated. It's an thrilling experience and I feel privileged to be in close contact with intelligent programmers daily. Right now I've stumbled upon an issue I can't seem to get a straight answer on - from all the blogs anyway - and I'd like to get some insight from the community. It's about Editing (read: Edit action). The bulk of material out there, tutorials and blogs, deal with creating and view the model.
So while this question may not spell out a question, I hope to get some discussion going, contributing to my decision about the path of development I'm to take. My model represents a user with several fields like name, address and email. All the names, in fact, on field each for first name, last name and middle name. The Details view displays all these fields but you can change only one set of fields at a time, for instance, your names. The user expands a form while the other fields are still visible above and below. So the form that is posted back contains a subset of the fields representing the model. While this is appealing to us and our layout concerns, for various reasons, it is to be shunned by serious MVC-developers.
I've been reading about some patterns and best practices and it seems that this is not in key with the paradigm of viewmodel == view. Or have I got it wrong? Anyway, NerdDinner dictates using FormCollection och UpdateModel. All the null fields are happily ignored. Since then, the MVC-community has abandoned this approach to such a degree that a bug in MVC 2 was not discovered. UpdateModel does not work without a complete model in your formcollection. The view model pattern receiving most praise seems to be Dedicated view model that contains a custom view model entity and is the only one that my design issue could be made compatible with.
It entails a tedious amount of mapping, albeit lightened by the use of AutoMapper and the ideas of Jimmy Bogard, that may or may not be worthwhile. He also proposes a 1:1 relationship between view and view model. In keeping with these design paradigms, I am to create a view and associated view for each of my expanding sets of fields. The view models would each be nearly identical, differing only in the fields which are read-only, the views also containing much repeated markup. This seems absurd to me. In future I may want to be able to display two, more or all sets of fields open simultaneously.
