Forms Data Controls :: Detailsview Clears Filled In Fields?
Aug 26, 2010
I have a details view on my page that has a template field in it. In the template field is a button that when clicked, sets the visible property of another field to true. When this happens the whole detailsview resets and anything that was entered into other fiields is cleared. Is there any way to prevent the other fields from being cleared when the hidden field is set to be shown.
I'm using asp.NET MVC, and am looking at the JQuery autocomplete plugin for what I want to do. I need some extra functionality that I don't think it provides.
I have a page with two text fields, First and Last name. Ideally, when someone begins typing into either, I would like autocomplete to display both the first and last name of all matches. If one of these matches were selected, I would like only the appropriate (first/last) name to go into the current field, while the other field is also filled in with the appropriate name.
So the problems here are that A) I would like the suggestion text to be different from the value that would be filled into the current field, and B) I would like to update multiple fields from a single autocomplete. Does this make sense? It seems to be difficult to find information on this situation on the net.
In this case I'm having, the ItemTemplate for various fields in my DetailsView (2 in my case) does not show up, but when you click the edit button, the EditItemTemplate shows up. I played with it, moving it around. No matter where I put it, one of the fields did not show up.
To get even stranger (and don't ask me how I came up with this), if I put a dummy boundfield BEFORE it, the ItemTemplate shows up. But this is totally absurd.
I have created DetailsView in designer page with SqlDataSource, Details view is with autoGenerateRows="false" i.e. I have declared my own fields. it is fine there, but what if I want to add these fields dynamically from codebehind with select & edit commands. I want to to use Details View in designer page and want to add fields from codebehind
I have a working gridView/DetailsView used as a member Lookup.
Some Fields in the Details View have data only some of the time, and when there isn't any, I want to suppress that row of the detail. No Go.
It seems that some of the function available in other controls don't exist so I cannot make the "field and its "header" Visible = "False"
FWIW, The control is nested inside a loginview control.
[Code]....
When I try and put logiin the control the error I get is:
Error 156 Literal content ('<asp:TemplateField ItemStyle-Wrap="false" HeaderText="PO Box:" Visible="') is not allowed within a 'System.Web.UI.WebControls.DataControlFieldCollection'. C:UsersBillDocumentsMy Web SitesNausetNewcomersMembershipCopy of Lookup.aspx 345
I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.
Im not sure what i could have done wrong here but i created a dataset (ran a query and it returns the correct data) - created my BLL class - bound the ObjectDataSource to the control using the BLL - ran the site and all the data is showing as expected. Now i click edit columns (from DetailsView smart tag) and the selected fields are empty. I refresh the schema and this makes no difference. What could i be doing wrong?
I have set a couple of my DetailsView fields to readonly=true. In Update mode the fields are readonly but in Insert mode they are not readonly. What do I do to set it to readonly or blank (no field for entry)?
When you click the edit button in detailsview I want it to store some values in "PreviousAddress" and "PreviousVehicle" to show what the data used to be before it was edited... Just wondering what would be the best way of doing this?
I'm not sure if you would consider it a foreign key field or not, but I have an agency table with an association to my Project table. It exists primarily to limit the input values of agency in the Project table to those listed in the Agency table. Anyway, everything works fine, except that when you insert/add a project, the Agency field is moved to the end of the list. I'd like to move it back where it belongs (further up the list).
I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
I have a detailsview in insert mode. I want to prompt the user to enter data in all fields, if left empty. Could someone please find a few minutes to show me how to do it?
I'm using a Gridview with Paging enabled. Also i'm using the Datakeys in Gridview. I can able to get the DataKeys values on first page. But when i click on the second page, i'm not able to get the DataKeys values. How to get the DataKeys values on Paging.
I have a Repeater and an update button inside the repeater
[Code]....
When I run this databound control to wire a javascript function it clears the viewstate and I don't get itemcommands. When I remove the button attributes command it works.
[Code]....
Obviously I can find a more creative way to add the javascript function, but this was the clearest way. Can anyone determine why adding an OnClientClick even in the ItemCreated would cause viewstate to fail?
I have a GridView with two templatefields, one with a DropDownList and the other with a TextBox, both loose their values once I hit the "update" button. Is it any way I can make the controls keep the values?
I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
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:
What I have is a datatable being constructed from Sharepoint API. We dont need to worry about the sharepoint api.The code where it fills the data is as follows
Datatable dt = new datatable(); Sharepoint.fill(dt);
Write what I want is as the dt is being filled is to create another column called full path which has a formula col1+col2I dont want to do a for next loop after the dt is filled . very slow !
I'm having major performance issues with my BBCode/Commenting system. It's taking 3 seconds to process the code, with 5 comments and a simple [b] command.
So here's what I am doing (it's done like this because of the way my backend system is designed):
"LoadComments" function is called with referenced to the repeater. "PagingSystem" is initializedBind data to controlData is pulled from the binded control (if bbcode is enabled) Data is put into a dataview Process text and convert BBcode (update row) BindData I disabled every feature, including the BBCode, and it's still loading slow. This is the ONLY thing I can think of causing the issue. Here is the base code that process bb:
[Code]....
As you can see, it uses my own data management code. Even without using it, I'm still not 100% sure how to modify the contents inside of a repeater. I don't see how modifying them could slow it down so bad..
I have a Detailsview working fine in ASP.NET 2.0 VB. where I can obtain any links or articles detailing the settings for the Template as a guide to me apply RegularExpressionValidators to a number of the fields in my application.
My application works fine with the Required Field Validator. The majority of examples that I have been able to find are using this particular Validator.
