I have a databound checkbox control that displays items with different widths. In order to get a better outlook, I would like to set a fix width for each items in the checkboxlist control which has horizontal repeatdirection.
Here is the control:
[Code]....
I have a silverlight project that I need to resize the width.
What I need to do is have horizontal scrollbars appear when a user shrinks the browser's width to less than the page width of the app.
I've been pointed to the ResizeDiv function in my test page:
function ResizeDiv(height) {
var x = document.getElementById("silverlightControlHost");
x.style.height = height;
}
but I don't know what to do here. I've set the width to different values (x.style.width = 100) but that just chops the page.
Is this the right function/page to do this? What do I need to do to get horizontal scroll bars to kick in if the browser is smaller than the page?
[Code]....
set the width of the datagrid and hidden the head?
I have a gridview on a page but when the results are rendered they push the page out to the right causing you to have to scroll left to right.
Is there any way I can set max width on this?
Here is my code:

I want to render something like this (with ASP.Net Controls in the codebehind):
<ul>
<li class="first"><h1>This is a caption</h1></li>
<li><a href="#" title="" target="_self">Foo</a></li>
<li><a href="#" title="" target="_self">Foo1</a></li>
<li><a href="#" title="" target="_self">Foo2</a></li>
<li><a href="#" title="" target="_self">Foo3</a></li>
<li><a href="#" title="" target="_self">Foo4</a></li>
</ul>
<ul>
<li class="first"><h1>This is a another caption</h1></li>
<li><a href="#" title="" target="_self">Foo5</a></li>
<li><a href="#" title="" target="_self">Foo6</a></li>
<li><a href="#" title="" target="_self">Foo7</a></li>
<li><a href="#" title="" target="_self">Foo8</a></li>
<li><a href="#" title="" target="_self">Foo9</a></li>
<li><a href="#" title="" target="_self">Foo10</a></li>
<li><a href="#" title="" target="_self">Foo11</a></li>
</ul>
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.
I have a GridView with bound columns, for which I am manually setting the ItemWidth and HeaderWidth to 500px, and nothing happens. Is there some trick to getting this to work?
This is a column a large amount of text in it, and it keeps sizing to the width of the header text, which is simply "note". I don't want to set Wrap to false, becuase then the colummn could be thousands of px wide in cases.
I have a GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).
View 2 RepliesI have a CheckboxList that seems to load and do everything right, except for when I do a postback, it will not have the Item.Selected property set. I have viewstate disabled for the entire page.
I load it like so(inside Page_Load on every load):
foreach (DataRow service in d.Tables[0].Rows)
{ [code]...
and MyLabel never has any text added to it. I can verify with the debugger that it does reach the _Click's foreach loop, but no item is ever selected. What could be the cause of this?
I am trying to set the width and height of images in a datalist in the codebehind.
The plan is to do something more complex than this based on the width/height, so setting width and height in the aspx file to 50% is not an option.
For some reason I always get 0 for width and height. Image1.ImageUrl is what i would expect though. Image is the System.Web.UI.Webcontrols.Image, not a System.Drawing.Image.
[Code]...
is there possible to control the table (tr, th, td) width in cs code? i dont want in HTML.

View 2 Repliesi have a FormView, and i already have a Label control that gets the value of theselected propery inside the FormView, so each time the FormView displays data, i have a Label control that displays individual values, according to the value of the FormView, here is the code:
[code]....
What i would like to do is to know how i could add a DataList instead of a Label, and then each time the FormView databinds an item, to show the value of the DataList How would i go about doing that?
for the radiobuttonlist control, when I try to style individual buttons with 'span'I get a error, is there some way to style each button?
[Code]....
error is:
System.Web.UI.WebControls.ListItemCollection must have items of type 'System.Web.UI.WebControls.ListItem'. 'span' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl
The width of the gridview control got increased in the browser, Because of that I got Horizontal Scroll. I don't want to get Horizontal scroll in the browser.
Below is the code .
<table align="center" width="100%" style="table-layout:fixed;">
<tr>
<td style="width: 115px">
OR</td>

I am fairly new to asp.net programming. I found this custom control that uses ajax to update the contents of the control and it is working perfectly. However, I need to access some of the asp.net labels and images in the databound event so I can set their values/properties appropriately, and am not sure how to go about adding additional code or accessing these in my custom control (I have been googling endlessly with no results). My code for the custom control is below.

i am developing a tree view component which should be data driven and amendable instead default layout provided by .net can we change that proper hierarchial structure like organization chart is there any chance to provide with an hyperlink to redirect other page or content view control below to display the content related to it.
i am trying to use silverlight with c#.
SqlCommand _cmd1 = new SqlCommand("Viewstate2", _cn);
_cmd1.CommandType = CommandType.StoredProcedure;
_cmd1.Parameters.AddWithValue("@behcode", data);
string data1 = Request.QueryString["id"].ToString();
_cmd1.Parameters.AddWithValue("@id", data1);
_cn.Open();
SqlDataReader _dr1 = _cmd1.ExecuteReader();
while (_dr1.Read())
{
lblprice.Text = _dr1["price"].ToString();
Lbldate.Text = System.Convert.ToDateTime(miladitoshamsi(Eval("Date"))).ToString(" yyyy/MM/dd");
In the above code I get the following error

MY Drop Down width is Different in IE and Mozilla
How to make constant width in both browsers.
I have a dropdown list in a gridview field. The DataValueField for the ddl is an 8 digit item code. The text to display through will be quite longer, 40-60 characters because it will combine the item code and item name into a single string. I don't want the dropdownlist field to be that wide though, only what is displayed when the ddl is selected.In Access you can set the width property of the list to display wider than the field itself. Is there that capability in ASP.NET and if so where do I find it?
View 2 RepliesIs there any way to set the width of a GridView to a pre-determined width?
I have set the width of the gridview and all the columns to a % and then to a number of pixels but it does work. The gridview always sets itself to a width required to display all fields and it goes beyond the resolution of the screen. I would like to contain it to 1024 pixels.

I have an AJAX tab container with 2 panels within aspx page. Each panel hosts an ascx control. Each control contains GridView and FormView that are databound - 1st control to the parent table and 2nd - to the child. The 2nd control/tab contains standard DropDownList that is bound to the parent values so the user can select a parent to create "child" for. everything works fine except when the parent (on the 1st tab control) is created/updates the ObjectDataSource on the 2nd tab does not getting refreshed. Only after refreshing the hole page I can see the new "parent" value in the ddl on "child" page. I use strongly typed dataset. How I can programmatically refresh the DataSource? Simple rebinding didn't make a dent. Do I need to refresh page, the tab container, tab panel?

I have a repeater I've databound with a generic arraylist from a LINQ query (.ToList() ) in the code behind.
I was using
<%# Bind("FirstName")%> but noticed
<%# Eval("FirstName")%> works just as well.
Is it better to use Eval or Bind? or does it depend on the situation?
I have a checkboxlist control in ASP.NET
<asp:CheckBoxList ID="chkchrges" runat="server">

I am binding in following way
chkchrges.DataSource = objclsChargeMaster
chkchrges.DataTextField = "chrgdcd"
chkchrges.DataValueField = "chrgcd"
chkchrges.DataBind()
And i am trying to get values (value member) of checked checkboxes
I am trying in folllowing way but each time it rerurns false on
li.Selected
For Each li As ListItem In chkchrges.Items
If (li.Selected) Then
Dim XX = li.Value
'' Do something with Value
End If
Next
How do I get the width of a control in javascript if it hasn't been set by a css file declaration, a Style declaration, or a skinID.
I have tried control.width, control.getAttribute.width, and I get nothing!
