How would I change the height of a label in runtime?
I want to change it from 23px to 56px to display one error message and the rest of the time have it set to 23px.
I believe it has to do with the pixels that cant be converted in this way?
I am checking if the the labels height is bigger than the panels height.
If that is the case, I am trying to set the panels height == labels height.
[Code]....
The characters that are entered in the text box will be displayed in the label at the button click event. Label is having fixed width for ex,200px but the height is not set for the label. By changing the characters in the text box,and firing the button click event the label will get populated with the text from the text box. At that time label width will be constant but height will change dynamically according to the no of characters entered in the textbox. Here I need to get the label height in pixels on the button click event?
View 8 RepliesI 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".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>
<iframe id="hdnFrm" name="hdnFrm" src="" scrolling="yes" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0" style="width:90%;height:90px"></iframe>here is my iframe. This in on a php page on a different website. Right below the iframe is a form. The form posts variables to a page on my vb.net website. The codebehind processes the data in the form. The results of processing are sent back to the iframe above.When this happens instead of the height beinc 90px, I want to change it to a different number.How can i do this?Do I set up some type of "listener" for when the controls arrival.

<asp:Label
ID="Label2"
runat="server"
style="line-height: 22px; font-family:Verdana; font-size:12px;" />
But I want to set the line-height dynamically.
I have been trying code-behind like this:
Me.Label2.Style.Add(HtmlTextWriterStyle.Color,"green")
There does not seem to be an enumeration for line-height though.
I have a treeview inside a TabPanel but I have problems with the panel's height. It´s not resizing automatically when I expand the nodes in the treeview.
View 1 RepliesI now that I can just define the width and height of a page with the div tag to allow for dragpanels to work, but it messes things up with some browsers when rendering, sometimes shrinking the actual content to allow for the complete page and width to be shown such as on the IPAD. I have tried the Javascript below, but it doesn't work, and whenever I try to resize a page manually, it puts my computer into never never land.
Anyone have a clean Javascript that will change the width and height dynamically as I am moving a dragpanel.
I can move the dragpanel, but it snaps back as soon as I let go so in essense it doesn't work.

I have a problem with setting field height. The thing is, I have report section like this :
PO or SH is name of group and on the right, there are properties for group ("H", "101", "--" .. etc.).
As you might see that property label height and group label heights are not the same and it looks bad. What I want to do is : to set group label's height and property's height as the same. I am using Crystal Reports for Visual Studio 2008.
I am using this code to generate the current date to label.
Label14.Text = DateTime.Now.ToString
It output as 5/27/2010 10:31:53 AM
However I want only 5/27/2010
How should I change this code ?
I would just simply like to change the size of an image or panel when hovering over it. What is the simplest way to accomplish tha?

It's basically how to create an editable gridview.
I've got it up and working, but I need to change the width/height of the textboxes when the gridview is in edit mode.
The problem is, when the textboxes are rendered, they don't have ID's so I can't use FindControl to modify the textboxes.
Adding textboxes in the template items just created an independant - textbox that doesn't do anything.
My question is, how can I find these textboxes & change their height/widths, or how can I find these textboxes & assign ID's to them...so I can modify their height/widths?
Here's a snippet of what I've been playing with....haven't had any luck though...I'm probably way off:

I was hoping this is simple but i have problems.
Basically i was only able to set the string color with itemstyle-Forecolor.
But how do i set the background of a column and also set height,width.Ok height may not work because i have an itemtemplate with predefined height.
Can this be done in a simple boundfield or must i have all my datafields in itemtemplates?
What i do for one column:
[Code]....
I have the folllowig css:
div.ListDiv {
width: 750px; /* Table width will be 99% of this */
height: 320px; /* Must be greater than tbody */
overflow: auto;
}
table {
width: 99%; /* 100% of container produces horizontal scroll in Mozilla */
border: none;
}
table>tbody { /* Child selector syntax which IE6 and older do not support */
overflow: auto;
height: 215px;
overflow-x: hidden;
}
thead tr {
position:relative;
top: expression(offsetParent.scrollTop); /* For IE5+ only */
}
thead td {
background-color: #CCCCCC;
font-weight: bold;
}
td {
color: #000000;
text-align: left;
}
table tfoot tr {
position: relative;
overflow-x: hidden;
top: expression(parentNode.parentNode.offsetHeight >= offsetParent.offsetHeight ? 0 - parentNode.parentNode.offsetHeight + offsetParent.offsetHeight + offsetParent.scrollTop : 0);
}
tfoot td {
background-color: #CCCCCC;
}
td:last-child { /* Prevent Mozilla scrollbar from hiding cell content */
padding-right: 20px;
}
When I have a list with 1 or 2, rows the row height automaticaly expand to fill the heigt of the table.
How can I avoid this happening, and have fixed height colimns.
I have a HyperLink inside a panel.
I wonder if the the HyperLinks height can follow along ´automatically´ as the Panels height is changing as the HyperLinks is nested inside the Panel.
Is there a function for this?

View 2 RepliesI have a gridview inside a tabcontainer.I'm programitically binding to the gridview. All works fine, data is displayed. And after databinding I'm dynamically setting the tabcontainer height to that of the gridview so that the gridview doesn't overlap the tabcontainer and look all funky.This all works fine doing this...tabcontainer1.height = gridview1.heightUntil there is no data returned, in which case I get a really small tab container.Bascially if there is no data, I want the tabcontainer1.height = 500, and if there is data to set it to the height of the gridview.I tried this (plus other variations) but can't seem to get it to work.

I have a Imagebutton in gridview that displays an image when i click.I am using jaxToolkit:ModalPopupExtender control for display the image.The problem I have is that I only want it to display an image based on another fields like width and Height.After clicking the Image button the image should display exact width and height as in ImageWidth and ImageHeight fields in table.My table structure is
Imageid bigint, ImageWidth bigint,ImageHeight bigint,Image varchar(128)
I have 2 panels in my page with their height is fixed (ex : Panel1.Height = 200px, Panel2.Height = 300px)
I am using CollapsiblePanelExtender to collapse/expand the first Panel by clicking on an ImageButton.
If Panel1 is hidden, change the height of Panel2 = 300 + 200. And if Panel1 is shown, change the height of Panel2 = 300.
How I can do that ?
I need change htmleditor height in javascript function in pageload.
View 2 RepliesI have a panel and a background image. to stretch this image in the panel if the height is adjusting. I have tried to google this but have trouble find a solution for this.The image has the size: (647 X 158).
The only thing that will change is the height of the panel. Now it does repeat by default. no - repeat will probably only make the image its orignal size wich is not stretching it out over the whole panel.Otherwise I am thinking of change the size of the image itself in C#. [Code]....

Access to my application is controlled by user accounts. I would like my text labels to change within my pages depending on the user logged in. This needs to be easily managed.
What is the best way to achieve this? Would using the resources file work?
