Forms Data Controls :: Listview Toggle Visibility Of A Textbox Based On Data Not Null?
Sep 3, 2010
I want to toggle a Textbox to be visible (true, false) contained within an InsertItemTemplate based on the data being Null/Empty.
It Works in the Item Template since it is calling the "select parameters", but once it is in the "insert parameters" on databinds, I am unable to get this to work.
One task that I would like to make a lot easier, is to be able to toggle a control's visibility to off/false if a particular database field is null. Is there an expression I can put in the visibility='<%# %>' part of my code that could handle this?
I have a tablix with subtotals at each level in the header and footer of each group. I know how to toggle the header textback to Hidden when expanding that group, but it then leaves a jagged appearance to he whole report. If I leave it the way it is, I have subtotals in both the header and the footer. What I'd like to do is to blank out the subtotal text in the header when expanded so only the footer is showing the subtotal, thereby retaining the header's textbox's color, borders, etc. and generally eliminating the jagged-looking right edge of the tablix.
I've tried accessing the Hidden property of the matching footer subtotal without success. I've even tried counting rows in the text-color expression of the header, but to no avail. Does anybody have any ideas on how to toggle the subtotal text in the header without creating a gaping empty space in that cell? I'd like to write something like,
=iif(ReportItems!sumFtrCustomerHours.Hidden,Sum(Fields!Hours.Value), "") but ReportItems only have one one property - Value.
I am working with a formview edititemtemplate. Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values. These dropdown values get binded during page load. I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.
I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback. I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render. I'm just not sure how to get the stars aligned here. The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender. However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.
I am simply trying to change the listView template based on a value in the listview data. I do have this displaying the information correctly. Except when I try to change the item template based on a value in the listview. My code is below ....

I traced the flow using the debugger. When the page load, txt_Cat_ID.Text = "2" correctly resolves to FALSE and the toggleOptionsDiv script is run with the 'hide' parameter. The page correctly hides the div.
When I click on the link that makes txt_CAT_ID.Text = "2" resolve to TRUE, the code executes the line where the toggleOptionsDiv script is run with the 'show' parameter. However, the div remains hidden.
The link that is clicked triggers an asynchronous post back and I'm not sure if that is the problem. How can I get the div to display on postback?
I have a set of server side combo boxes in a table. Based on client events, I need them to appear or disappear. I've tried the following with no success:
m using a listview and an object data source in my application, with optimistic concurrency control.i have only 2 columns in the listview: category_ID and category_name;when i try to delete an item, an error message is generated saying that one of the old values populated by the list view is null, i performed debugging, and found that the category_ID old value is populated correctly, while the category_name old value is populated as nulli can't find a problem in the code, i executed the delete command in the query builder directly and it worked fine,
I come across the technique on how to apply a different CSS class to make a row stand out from the others. However, the original code is for gridview whilst I am trying to get it works on a listview. The original code for the gridview is as follows and how to get it done on listview.
I have a gridview. In the rowupdating event, the txtbox returns null. I have enabled viewstate for the gridview. But still it does not work. I have made this in Kentico.
i have 2 template field columns time and total_time in a gridview.. time column has a label in the item template and a textbox in th edit item template..
similarly, total_time has a label in the item template and a textbox in the edit item templte..
what i need is, when the user enters a value in the time textbox,it must get updated in the total_time textbox.. and on edit,when the user changes the value of the time textbox ,dis value must be ADDED to the total_time textbox.. both should be displayed in the label also..
I have a listview that is retrieving some values from a database and showing them. The information are; product name, price, etc. At the end of each row, I have a textbox and a button. Within the textbox the user is able to insert how many items he wants of that particular item and by clicking the button I want the value from the textbox retrieved. It may be relevant to mention that with the button is a event attached (OnClick) which is where I want the value of the textbox to be retrieved. The part that is giving me problem is retrieving the textbox value for that specific row when the button is clicked.
I have a ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.
