Web Forms :: Removing White Space When Aspx Label Is Hidden?
Feb 8, 2011
I have a page with several asp labels with no text. I use a click event to add text the fields that have related values from a datareader. In my code I state that if column value of the datareader is null, then make the label visibility false.
[code]....
That all works fine, but then when I render the page, white space where the hidden labels are located is shown.is it possible to remove the blank white space when labels have null values and are visually hidden?
I am currently working on an invoice report which may or may not span across multiple pages. I have a header which I have setup to only be displayed on the first page, and a footer which I have setup to only be displayed on the last page. The problem is, the hidden header/footer reserves unwanted whitespace and messes up the report layout (see the screenshot). The black areas represent space that is reserved by the header/footer. There must be a simple way to remove this unwanted space.
I found an useful link which show tutorial for setup Gridview export to Excel.http://archive.aspsnippets.com/post/Export-GridView-To-WordExcelPDFCSV-in-ASPNet.aspxIt works well but if I want to preserve white space for certain boundfield, after the excel export, I got merged cell for every row. how do I avoid the merged cells?
I am having problems with rendering differences between a gridview control and a local report .rdlc rendering. The dataset shows different spacing between characters in the dataset visualizer than it does in the gridview. The sql reporting services report is more closely rendering what is shown in the visualizer. The dataset is filled From a DAL and then bound to the gridview and reporting service at runtime. I'm currently using VS2008 and programming in VB.
In my website, users have the ability to upload images to my website. When the image is uploaded it will automatically have a smaller thumbnail created by my website. The thumbnails are not displaying correctly in my repeater though (and by correctly I mean Im not sure how to display them).
Each image sits inside a square div element which is 145 x 145 pixels. Some of the images are 145 wide with a relative height and some are 145 high with a relative width. When my page is displayed the wider images sit at the bottom of my 145 x 145 div,whereas the higher image sit at the bottom and to the left. I would prefer them to all be centered.
I cant find a way to do this is in CSS becuase the images are retrieved dynamically so I cant assign a height beforehand. Is there a way to add white space to my image during the thumbnail creation process so that all images are 145 x 145 but still maintain the aspect ratio? Or can someone think of a good way to do this with CSS and HTML, OR even with javascript (keeping in mind that my images come inside a repeater bound to data in the db.
If you want to see any of my code or the thumbnail creating class just ask.
I'm trying to remove all white or transparent pixels from an image, leaving the actual image (cropped). I've tried a few solutions, but none seem to work. Any suggestions or am I going to spend the night writing image cropping code?
In my ASP.NET application, I was trying to add few white spaces between two text boxes by typing space bar. The equivalent HTML source was instead of . So I just wanted to check: is this the new replacement for white space? If yes, why they changed?
The table cells on the List.aspx all have an inline CSS style that prevents the text from wrapping. Sometimes I want the cells to wrap. How do I prevent the inline CSS from appearing?
I am trying to achieve freezing the first column not to be scrollable horizontally and i am able to achieve but having two gridview inside a table with two td's. The problem what i ma facing is i am getting some space between two td's. attached the image for reference and below is the my code.
If you use the multiview and view controls you'll notice that there's about 1/4 of an inch of unusable space at the top of the view.Is there any way I can eliminate that space?
I think that there is a good solution to remove white spaces from aspx page and from aspx.cs files. There are some solutions how to remove white spaces from html (aspx) but there is nothnig about aspx.cs.
i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).
i would like to call the external js file's function onclientclick event, but how can i pass the parameter, which i get from the hidden field value from the same aspx file.
I have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden(); t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType"); if (t.Value=="GV") { assign one template} else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.
I have a user control that i have registered to an aspx page. Now from the aspx page, i am trying to access one of the registered usercontrol's hiddenfield value in my aspx page using javacript using the below code:
I looked into the page's trace, and i could see 'control1$hdnField'. Then why i am not getting its value in my aspx page. I have also confirmed that the hidden field by this name exists in the user control and also has a default value set.
I am trying to use the key value pairs with the AutocompleteExtender to allow a user to select a name of a buyer from an autocomplete list and then insert the pkId of the buyer from the database into a hidden label for later use. I can get the Autocomplete part to work; however, when I fire my btn_click event to save my form information I lose the value of the pkId. Also if I try to hide the label I get javascript errors as if the control isn't even there. I have tried hiding the control by using the visible attribute as well as style="display:none;"
I wrote a small .NET applications that removes all line breaks in aspx/html/css code to make it harder to read for people trying to steal my design. And surprisingly I get weird characters that appear out of nowhere such as Â, » and others. They all stay at the same places, but I have no clue why they appear.
I am working on Scott Mitchell's ASP.Net in 24 hours book. I am running into what looks like a simple problem that is getting the best of me.
When a page loads, the UserId of the currently logged in user will be retrieved in the page Load event and placed into the Text value of a Label. But, when the page opens when I am running the app, I am getting an error in the lower left corner of the browser. When I open up the error message, I see this:
