Is it possible to not render a label control unless there is content in it?
I have a situation whereby the labels need CSS padding, but when there's nothing in the label it still obviously renders the <span> tag with the padding, and it looks odd having a huge gap on the page (looks fine when there's content in the span, but not when there isn't).
Or can I set the CssClass conditionally only when there's content?
I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
i have a dropdown in a div which is toggeld visible true false the dropdown is populated with data on page load (is not postback) but is visible false when i click a button to make the div with dropdown visible true the div with dropdown appreas but the dropdown doesnot conatin data.
Is it possible to display or hide a label based on the text rendered in it?
I have a label that will display the value of a control on the previous page. If the value rendered is "0" then I want to hide the label or hide the label and one more label associated with it. (or if the value is more than "0" make it visible.
My problem is when a label's text property has a value without space and bigger than it's width property. -Mostly when i enter a link url- The text of label exceeds the width of label!
I have a web user control with a dropdown that is populated from a SQL table:
[Code]....and then the .cs
[Code]....
Catalog Access:
[Code]....
I can give the rest of the GenericDataAccess if that will help, but here's the problem; When I run a web page with this control, all the dropdown items are 'System.Data.DataRowView'I'm sure there's some obvious stuff I'm missing but I'm new to populating dropdowns.
I have 2 dropdown lists on a WebForm. One of them is populated in the page's Page_Load event. This oneworks fine with the following code.
[Code]....
Then, after a value is selected from this list and a date is selected from a DateTime picker, then I click a button which is supposed to populate the 2nd dropdownlist. In the debugger in the button's click event I can see that the dataset is being populated with data, but then the list is never populated after the DataBind() method is run. Here is code from the button's click event.
I have a DropDownList populated with a SQL Stored Procedure. On the page, there is also a button that when pressed, processes the contents of the dropdownlist. I would then like the dropdownlist to automatically remove the selection, and if there is nothing left in the dropdownlist, I would also like the button to be disabled.
I have two drop down lists on my page. One (DropDownList A) has the values preset by me. The other (DropDownList B) has its values filled by a database query if a button is pressed. Each of them have AutoPostBack set to true. Each of them have corresponding onselectedindexchanged functions. DropDownList A works fine. When I change it, I want it to turn itself invisible. It does. DropwDownList B is not working. When I select something, it does the postback but the selected item is reset and the onselectedindexchanged function is never called. I feel like this is a problem I've solved in the past, but it's been 3 years since I programmed ASP.NET. All this is done in C# by the way.
i am currently working on a webform that has several dynamically populated dropdown lists. this works just fine, however, i have other web controls that require to have a postback..and at the time the page postsback, it reloads my dropdownlists, reseting whatever option i had chosen...
I saw first few video tutorials and they seemed to get the values from the control like text = Textbox1.text; All the form fields are got this way. On the other hand in mvc all the request parameters are populated into a model object. I am not sure whether this already exists or not, but is there any mechanism built-in asp.net which would populate the data from the controls automatically and give us a nice model object which can be saved directly onto the db. Something like this:
<asp:textbox ... ... value="${model.name}">
I don't remember the exact syntax of textbox control. So in this case the textbox would be filled when get request and put into model object when posted back.
Item Selected in MediaTypeDDL determines values in MediaFormatDDL. I'm using Javascript to populate MediaFormatDDL. This is working. I now select the item I want from MediaFormatDDL. That works The problem I'm seeing occurs when I press the button to save the values from the screen. I don't see the Item I selected from MediaTypeDDL. All the other fields are okay. This must be someThing simple, but I'm not seeing it.
how to programmatically create an ASP.NET Menu Control populated using LINQ to SQL (with an unknown number of levels) and couldn't find one anywhere. It took me a while to figure out the logistics of it so I thought I would post my final solution so that you don't have to spend time figuring this out for yourself. Note that I am a self taught developer so I am potentially breaking any number standards coding protocols.
In this example I am working with an ASP.NET project named Virtual. Non-Standard NameSpaces are Virtual.(tools, components) etc...
1. Create your database table that will eventually be used to populate your menu control.
I've got a dynamically populated drop down list and was wondering if web crawlers are able to see dynamically rendered data? Here is my static html below, and the end result to the end user is a drop down list that's populated from my SQL query within my datasource below.
I have a listbox that I am populating at runtime with javascript. After the listbox is populated I am using a button to get that value. on button click when I am trying to get the value it is the listbox item count is 0, Can anyone tell what's wrong after t he javascript populates the code,I have written the code in button click :
for (int i = 0; listbox1.Items.Count - 1; i++) { string s = listbox1.Items[i].ToString(); }
the value of count is showing as 0, though it has the values populated. What I am missing ?
