Forms Data Controls :: Fill DetailsView From Two Data Tables?
Mar 17, 2010
I'm using VWD 2008 and using an SQL database with a simple web app.
I've created a SQL query that pulls data from several tables. When I execute the query in
the query builder tester, it executes OK. I'm binding the DetailsView to an ObjectSource / DataSet / TableAdapter Querry with a variable that is bound to a listbox control.
Again, the query runs fine in the query builder.
When the detailsview or gridview gets built on the page it only displays columns from one database yet it executes ok within the query builder.
I can see the generated code for the detailsview does not create fields for every field returned by the sql query ?
I have one more time a problem with a DetailsView..I would like to fill a TextBox (or Label) with a function in my DetailsView and on the Update getting value contained in this control.
It works fine when I don't use a personnal method like Bind("..") but if I try to use my function it throws an error
[Code]....
That's what I use for now and it works but I would like to fill TextBox2 with value returned by my function and update datas with this value.
I have a asp:DetailsView control with the first column are the field headers and the second column is the record details for a given user.
The DetailsView is bound from 4 tables, I need to be able to edit/amend any field. Is there another way I can achieve this from the DetailsView? Would I need to create templates for each table entry then Update SET on each template, would that do it?
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
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.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
I have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?
I get data using sqldatasource control (about 100 reacords) and fill first dropdownlist with this data , I want to fill the second one with all othe data without one which selected in the first one ( I want to remove selected record from datalist and fill others in next dropdownlist) . and repeat this operation for all 25 dropdownlist. (i want in final 25 value without dublicate )
I need to fill a label or text box either one with sql data.
I have an datagrid with rows of resumes submitted and i have the pk_id in the querystring and when the hr department clicks on the id it opens up the resume and I need to fill in the data from sql in the format of the resume.. so therefore i need to be able to load sql data into a label or text box.
I have a formview and I want to do a lot with it.First I want to go from page a to page b where page b is a formview in insert mode.After the data is in a database a want to go to page b in select mode (readonly). With a button I want to go to update mode, so you can change your profile.But whatever I do, I stuck with filling up the formview and get the right data.My prograexist off fist make a user with a create user wizard.
I have a formview and I want to fill it at page_load. The formview must show the data of the person that has logged in.So the question is how can I fill the formview so that is shows the data of the right person (UserId = @Param2) so that the formview is in editmode?
I have bind the Repeater control . After filling the Repeater control . I am dynamically binding the Dropdownlist. Now , if i have 3 rows in repeater the last two rows are binded in dropdownlist but i am unable to bind the first record's dropdownlist. Here's my code for dropdownlist binding
I have a Grid and it is filled with a list of objects... the problem is that in one column i want to show the name of one of his proporties... the problem is that this property is other object... I mean, my object medication has inside other object called producer.. so i want to show the name of this producer..
[Code]....
on the column Producer the thing that appears is : Entities.Producer.... but i want to show the name.. I tried with Producer.Name but in this way i have a error.
I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:
I use ObjectDataSource and DetailsView for Updating records . my Bll input parameter method is an Object instead of regular parameter . So i though i could make my own ObjectParameter in ItemUpdating event of DetailsView and i need some modifiation on the data that user input on boudfield in detailsView . I don't know how to access BoundFiled data from ItemUpdating Method of DetailsView.
I have a database containing a table with about 700,000 images so I recently enabled Filestream. However, I can't figure out how to render the images.
I have an Imagefield control within a Detailsview which is using an .aspx file to render the image through the DataImageUrlFormatString (which is typical). In my select statements I tried changing the binary field containing the image from objectdata to objectdata.PathName() per the Microsoft documentation but this does not work. I get the red X image box.
Just want to know if it is possible to Dynamically Populating a DetailsView with OleDb Data Adapter ? It has to be done on the Page_load because it has to display a users details that i must be able to edit!
I use a Detailsview, Entity Data Source to edit/update my table with only 3 columns.(it has primary keys).
Everything works fine inserts/edit in dev environment. but when i run this in release mode. i cannot update existing data in the database with the detailsview. whenever i update and save page gets refreshed, but nothing gets updated. but whenever i insert a new record, and then i try editing it. it works.?
Note: i handle DetailsviewItemUpdating,DetailsviewItemInserting events to do some custom checks.
I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView
[Code]....
The code of the fields that hold the DDLs in the DetailsView control
