Javascript - Assign ID To A Field In DetailsView?
May 24, 2010
I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time.
I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do?

A TemplateField of a DetailsView can be assigned a value easily at any of many event handlers such as Load, PreRender, etc. when the page is loaded. However, after Insert or Cancel is clicked, all the fields are cleared. I cannot figure out how to assign a value to the field again in code-behind.

The detailsview is used for logged users to add a new item to a table in my sql database. The detailsview default mode is set to "insert".
The UserID is a field in the table in which the user enter the new record.
How can I get the UserID Guid value assigned automatically on pageload to the specific bound field in my detailsview

I am using a detailsview to show a record from the database for editing - or for inserting a new record. When a checkbox in one of the fields is changed by the user I want to hide another field. To avoid unnecessary postbacks I want to use javascript. Here is a simplified version of what I have so far:
[Code]....
I have been able to select the "txtPromoCode" textbox and hide it, but it leaves the headertext. I want to hide the whole field.

I now can reference a field in the formview, but, assigning it a value is fighting me.
I want to assign the UserName field in the formview with the login name from the Master (HttpContext.Current.User.Identity.Name).
(A) I tried the likes of: FormView1.FindControl("UserName").DefaultValue = username but of course that doesn't work.
(B) Alternatively, I tried to edit the SQL so that I passed it the HttpContext.Current.User.Identity.Name but didn't have any luck.
InsertCommand="INSERT INTO [TechUserName] ([CertName], [CertLevel], [CertLast], [CertFreq], [CertDue]) VALUES (@temp1, @CertLevel, @CertLast, @CertFreq, @CertDue)"
temp1.text=(HttpContext.Current.User.Identity.Name)

how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.

Is that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?

Using MySQL 5.
In my SAP.NEt project, defined a constant:
public static DateTime NullDateTime = DateTime.MinValue;
I have a function:
protected static DateTime GetDateTime(DataRow row, string columnName)
{
return (row[columnName] != DBNull.Value) ?
Convert.ToDateTime(row[columnName]) :
Globals.NullDateTime;
}
In the source code:
public DateTime StationFeedTime{ get; set; }
StationFeedTime = GetDateTime(row, "StationFeedTime");
I ran a SQL to fetch records from MySQL, this field is Time field in MySQL.
Got an exception inside the function:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.

Say I have a DetailsView with a bunch of fields, and I want only certain kinds of users to edit a few of them. They're too few to split them into another DetailsView, so what I'm thinking is to find some way to only allow a user to edit them based on some code-behind logic, effectively making them read-only at will.
I feel it's important to mention that the fields are both TemplateFields, not normal BoundFields with ReadOnly properties. For some reason the required functions don't jump at me from reading the documentation. Oh and I need eveyone to see their specific values, I just want to restrict edit access to them.

I have an ASP.Net detailsview control. Its DataSourceId varies and I set it in Page_load accordingly... (based on LLBLgen sub types, but this is not too important)I guess this is a page lifecycle leaky abstraction I am not "getting".The problem is that I bind to fields that may or may no be there depending on the datasource...To "disable" a bound field under certain conditions I've tried wrapping the bound field in a panel which I set to visible or invisible in code-behind, but I still get the following error:Sys.WebForms.PageRequestManagerServerErrorException: DataBinding: Entity does not contain a property with the name 'FilePrefix'.I change the detaislview.datasourceid in pageload...might be too late in lifecycle.I don't want to bind to that field, as it doesn't exist for the new datasource, but it tries to do so none-the-less and I get the error.[Edited]: Code as requested...ASP, detailsview bound column:
<asp:TemplateField>
<ItemTemplate>
<asp:Panel ID="pnlNormalAdditionalFields" runat="server" Visible="false">

I just can't figure out how to approach this, but this is what I want, would be I have a database-table containing an XML-field. Using LinqToSql I succesfully bound this table to a GridView and a DetailsView control.ow I wrote a WebUserControl that renders a bunch of textboxes, and has a method 'Serialize' that returns the XElement-object that I can use in my codebehind to assign it to the LinqToSql-property to save it to database. It also has a public property 'Xml' (type string) that I can use to Bind() the xml-string from the database to it, so the WebUserControl can prefill it's textboxes.

I have a DetailsView control in a VS2010 project. There are 20 fields, most of which have been converted to template fields. However, when I right click the control and choose Edit Template, I only see the first 15. I cannot choose to edit any of the template fields beyond that. The fields work when I run the project, but I cannot edit them via the designer. Is this by design or is something corrupted?

I am passing in a value to the form that I ultimately assign to a textbox using javascript. The value is a calculation based on values from another page/form. However, the textbox is editable.
When reloading the form with the previously saved data, I don't want the value of the textbox to be overwritten with the pre-calculated value from another page if it was edited manually upon save.
The other stipulation is, the page/form that has the values that the calculation is created from, can be changed. Therefore, I would also want to check to see if the calculated value has changed since last load, and if so, load that over the manually entered value.
So...
If textbox is blank populate with calculated value else if Manually entered value trumps calculated value else if calculated value has changed since last calculation, it trumps manually entered value.
The other concern with this all, is how do I determine if the user has typed in the textbox to determine if the value was manually entered?

I've got a Gridview which has a datasource to a particular database.
I've got a DetailsView which has a datasource to a table in another database.
when I select a Gridview row, I need to populate a field in the DetailsView with the Primary Key field (showing in the Gridview) from the Gridview.
Can this be done (if so, how?)?
Also (but not as important) :
If there's no field related in the second table, I'd like it to come up in Insert Mode - if there is a field related, I need it to come up in Edit mode
