I found this article [URL] on how to create a customvalidator for the checkboxlist. Followed all the way thru, but when i load my page i get the following error, how can it exist in 2 places? How can i resolve this to use the validation on the page?
Compiler Error Message: CS0433: The type 'CustomValidators.RequiredFieldValidatorForCheckBoxLists' exists in both 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot294f506e54827e67assemblydl3b4b5a368e15533_8dcfca01RequiredFieldValidatorForCheckBoxLists.DLL'and 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot294f506e54827e67App_Code.5yh9snf-.dll'
I have a page, there is a pre-created checkboxlist, for certain people it should be possible to add new checkboxes to the list.How should they do that? Here is what I have in mind.
Next to the checkboxlist there is a button (Add new items), when clicked a popup should be shown, there the name for a column (in a pre-created table MSSQL) can be entered (this column is only a text column), column is created and when clicked ok, the checkbox is added to the list (checkbox binded to the just created column).
I have a little question about building controls at runtime.
In my case I would like to create a checkboxlist in my page_load event
[Code]....
This control is a part of a wizard-Control. At the end after clicking the finisch-Button, the selected values have to sent by email to me. My question is, how can I get the ID of the Checkboxlist-Control whitch was build at runtime?I tried following workaround
[Code]....
But I get following error-message:
System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
I have a requirement to create our own MultiValueControls like CheckBoxList, RadioButtonList, DropDownList. I need a headstart, the usercontrols should have all the Even Handler implementation, setters and getters. Also,i will have a table which has the control properties(width, height, cssclass, etc) stored for that control. HOw to dynamically set the properties from the database to the usercontrol. This is required, because the requirement is for the Dynamic Form creation, I store all these ascx controls in the database and all the properties of the usercontrols in another table and map them dynamically.
I am using this modal pop up with animation externder, but my question is how can I enable the vertical sroll bar, if the textbox gets overlapped the browser? And be responsive if I am using mobile.
I need to charge my checkboxlist1 from database, eg load fruits and vegetables. When selecting fruits, new filter based on the previous selection in my checkboxlist2. for specific search.
But the problem is that, when the grid is placed inside the "Update panel" and if some button action fired, the scrollable grid with the fixed header is changed to the normal grid.
I wonder how it can be possible to "Flip" an image vertically and set it to a control. The code compiles fine but no image is set to the control, setImage1b ?
I am porting an ASP.NET 2.0 project to VS 2010 and ASP.NET 4.0. I have the asp.menu set up to go horizontally across the top of my master page. This works pretty good, but I have a couple of pages that take a long time to load a lot of data (that is another issue though). The problem that I am having is that when these slow pages load the menu is initially vertical and then switches to horizontal. This looks so bad that I had initially thought that it was displaying my sitemap page. I just want it to draw properly (horizontal) to begin with.
Also, the content page has a script manager with CDNenable set to true.
I'm also looking for scrollable Grid with freezed header, which is working in IE8. In above solution fixed column width is used. Is it possible to have a such grid where grid width is changing together with page width (when changed)?
I want scrollable gridview with fixed header. For that i create belw code
[Code]....
It works fine uptil page loads.I have functionality to delete rows from gridview.Once i click delete button from gridview the width of header columns get decreased then the width od data inside gridview.It means depending on the content of data the size gets variable.HOW to show data inside gridview irrespective of the content of data.
I am using VS 2010 and ASP.NET 4.0. I have the ASP:Menu in the top of my master page and it's orientation property is set to horizontally. I have a problem with some pages that take a long time to load data. The problem I am having is that when these slow pages load, the menu is initially vertical and then switches to horizontal after few seconds which doen't look good. I have tried to change Orientation in MenuItemDataBound but no difference.
The menu control when used on the newly released VS2010 with ASP.Net version 4.0 renders vertically briefly, then renders horizontally. This causes a 1/2 second annoying flash of the menu in vertical form before it disappears and renders horizontally as intended. If you choose to render the menu as a table this problem doesn't happen, but if you choose to render the menu as a list (using <ul><li>) then if happens every time, but is hidden on development systems where response is quick enough such that the rendering vertically is not visible to the naked eye. How can I cause the rendering to be horizontal (without the brief vertical rendering)?
I'm working with a databound gridview that has two columns: a checkbox and zip code. It works fine but upon rendering, it is a very long and skinny two columns which requires the user to scroll down a lot in their browser. I'd like it to be more user friendly and not require so much scrolling. tried to repeat it vertically by adding additional checkbox and databound column but just ended up with duplicate data, not continuing data from the bottom of databound column 1 to the top of databound column 2.Is there any way to repeat the columns vertically and have the data continue?
I have a ListView that is grouped into 4 columns. But the results are displayed horizontally accross the table. Has anybody any advice or resources about dispaying them veritically?
I am trying to draw a horizontal line and want to repeat an image horizontally so that it is 380px long. How do I do that? How do I also do it for a vertical line?
