Forms Data Controls :: ItemTemplate (Detailsview) For Certain Fields Does Not Show Up?
Jan 19, 2011
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 got a problem about finding controls in Edit/Insert Itemtemplate inside a DetailsView.Here is the code.I put a Label (id= "Label6") to test whether the findcontrol method works or not. Unfortunately, I almost tried every means but still coudn't find it.
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 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 Repeater displaying some data that doesn't do what I'd like to see. If a certain condition is met (ex: parent.NumOfChildren > 0) I would like a hyperlink shown. Here is what I have so far:
In this case, the "View Children" link shows up for every item in my Repeater, but I'd like it shown only if parent.GetNumOfChildren() > 0. Would it be correct to try setting the Visible="true/false" property of the HyperLink? Is that the norm for this sort of problem? Or, is there a way to wrap the entire <asp:Hyperlink> ... </asp:Hyperlink> tag in an if statement that has a reference to the object that is currently being interated in the Repeater? Ie:
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?
The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.
have table COLLECTIONS and table CLOTHES.As an example, when showing the items on Listview, collection HAWAII would be written on the top, and its texts and images on the itemTemplate.Then, collection WINTER and its texts and images on the itemTemplate.And so on.P.S: I´m connecting the Listview visually thru SQLDataSource, not programatically.How can i do it ? On the layout template using a JOIN on the SQL Statement ?
I have Master - Details relationship between GridView & DetailsView controls bound. So each time the GridView's index is changed the DetailsView image is updated.
However, after I fire Response.Redirect("~/theSamePage.aspx"), the DetailsView data does not get displayed.
All binding script is withing <asp> tags, provided declaratively on .aspx page
I have a gridview that allows you to select and a details view show up at the bottom. Is there a way to make the details view show in a new window instead,
