Forms Data Controls :: DetailsView Controls Not Recognized?
Jul 19, 2010
This is odd. I have a simple detailsView on an aspx page, which I dragged and dropped. I think edited each basic text box in the grid to either be a date picker, or a drop down list. This is working. I can see my data fine with no errors. This is an "edit" page, so when the user clicks "Save", I do a simple "update" statement. However, when I'm writing the code for the save button, the intellisense isn't picking up any of my control names?? Here's an example of my code:
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.
When I go to the page_load event in the codebehind, I can't seem to find this control at all. No intellisense whatesover. I've tried renaming, closing the solution, even changing the codebehind directive at the top of my aspx page to "codefile".
bolded part for extracting date in a label( lblRequestDate). is it ok by point of view security (I never get an error although the data may be complex)
I am developing web application using csharp on visual studio 2008. I am loading the data from Microsoft Excel to datagrid. But when I want to check the date in a given column and getting the error String was not recognized as a valid DateTime . How can I solve this problem? The code I am using is below.
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 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.
im using visual studio 2008, c#, asp.net, sqlserver to develop website. my problem is i want to change textbox control in detailsview when editing and inserting to other controls such as dropdownlist or radio button. is there any possible way to do it? i've try using edit item template, its work only to change it to other control but not working to bind it to database.
have two detailsview controls on the same page, one showing pictures, one showing the comment on the current picture. I separated them because they are in different parts of the page (just in case someone was wondering why). They both bind on the same objectdatasource. The issue is that since I use paging to navigate the pictures and i dont know how to also update the comment detailsview control to the same page as the picture.
I have to put my little details view controls (the 4 dates textboxes) side by side (horizontal align) to use more page space.what the best way to do this? javascript? DetailsView have an option to do this?
I created a new page in an existing project. The existing pages are still good, but the new page is having problems at runtime. The problem is that controls are not recognized and throw a "object reference not found" error. I even tried Page.FindControl and that didn't work either. This is only happening with this page. The controls are recognized at design time, and are not recognized only at runtime.
The controls were copied from a regular Web form into a content form with a master page. They worked fine when in the regular web form. Could that be the issue?
I tried creating a new page and moving the controls over, but that didn't fix the problem. I also tried deleting the designer file and recreating it (using convert to web application) but that didn't resolve it either. I'm out of ideas here. Here is the page directive and the first control that is not recognized.
I am having trouble formatting the date on a textbox I get the error above if I don't enter the date in MM/DD/YY format in the textbox. I am also using this in a FormView so I can't format it or don't know how to in the code behind so if there is a way to format it in design view that would be preferable. Does anyone have any ideas on how I would do any of this.
I want to filter a Gridview by date. I enter the date in a textbox and use FilterExpressions. I keep getting the error message: String was not recognized as a valid DateTime. How can I solve this?
I downloaded iTracker to get started doing some web development with ASP.NET. I don't understand why in the code behind file, the standard web controls are not recognized.
I need to access controls of aspx page and usercontrol page through the external .js file. I created a global varaible in the aspx page
<script language="javascript" type="text/javascript"> var loadPanelID = "<%=ajaxLoadingPanel.ClientID%>"; </script>
Now I pass this value in the onclick event of button click (Let the funtion name be Fun(loadPanelID) ) . The controls is recognised in the .js file. Everything is fine till now. Now i need to call the same javascript method Fun() from the button click of usercontrol.
<script language="javascript" type="text/javascript"> var loadPanelID = "<%=ajaxLoadingPanel1.ClientID%>"; </script>
I have ajaxLoadingPanel1 in the usercontrol and I have defined global variable as in the first one in ascx and passed that value to Fun() method. But this time it gives error called "loadpanelID" is undefined.
First of all, I'm relatively new to asp.net (3.5) and all of its controls. What I'm trying to do is to split up a detailsview. I have a submission form containing quite a lot of fields that are supposed to be filled out by the user. In my design I have a tabstrip with headlines about the different sections of the form. For example:
Tab1: Personal Info Tab2: Info about your car Tab3: Contact info
I have tested to add a new "user" via a DetailsView and it works. But what I want to do is to split up the contents within the <Field> tags In the DetailsView In different div classes (using css and javascript to hide/show the right tab contents). But when I try to do this Visual Studio says that characters like <p> and others aren't allowed within the Field tags, which makes sense. Is there any control to use for these kinds of situations?
getting error saying Operator '<' can't be applied to operands of type.TableCell' and int What am I missing? How does this differ from a GridView container?
What I'm trynna do is to input value in the TextBox1, and pass the string value to the label when button "ChangeText" is clicked.Pretty straightforward.
and how to use both of those checkbox (for example: when i click update in my detailsview, if the checkbox is checked will return 1 and if unchecked will return 0 and insert that value to database)
I have a detailsview which is used to input data into an SQL database. Some of the fields contain drop down menus which are populated from the database.
I also have a form that allows the user to select mutiple values from a listbox (populated from an sql database) by moving the required items from one list box containing all the available items into a second one containing the selected items. There is also a text box which is used to filter on the available items. When this is passed through to a stored procedure to be put into the database, it is passed as a comma delimited string containing all the selected values.
This works fine on a separate form, however I would like to include it in one of the fields of the detailsview. This creates a BC30451: Name 'ListBox1' is not declared error. I have looked for hours on the internet to try and resolve this but cannot find what I need for how to declare the list for use within the detailsview.
Here is the code for both the working multiselect form and the code for when I have tried to integrate it into the detailsview:
