I'm sure you've seen sites that display a portion of the available text in a limited space followed by an ellipsis or a [more] link. That's what I need to do. The text is in a database field, and includes carriage returns and line feeds. I can't just count the number of characters. How can I only display the text that will fit in a defined space? I've tried using a panel control with the height defined. I've also tried a div with the height defined. Neither has worked. How is this done?
View 6 RepliesI was wondering if people out there test the length of their text values before inserting them into an SQL INSERT or UPDATE command? I got lazy and stopped doing it lately but I do restrict the length of some of my character fields so that I have a NCHAR(50) field but don't test the length of the string when inserting or updating and just rely on the server to fire back any problems.Am I being 'efficient' or 'lazy' or even 'dangerous'?I appreciate the opinion of you as just about anyone has more experience with SQL Server than I do.

View 4 RepliesI have a check box list with some items. I want to make it a single selection. A Radio button list won't work because I need it to allow no selection. It may work if it has allows users to deselect the item selected(like in a check box). The second problem would be that instead of simple text I want a text with link.
View 3 RepliesIs there a way to check/uncheck the checkbox in a tree node by just clicking on the treenode text. I tried something like this - I can check the right checkbox when I click on the node text but I am unable to uncheck it. Is there a way to do that.

I'm new to programming and recently spent some time navigating these forums and searching google to learn how to manipulate Validations with ClientValidationFunction using JavaScript and OnServerValidate with C#. Now that I have a decent handle on it I wanted to give back a bit. I hope some of you all can use this information. Mess around with it and see what its doing and how.I'm using Visual Studio 2008 as my IDE. I did not include a master page so just copy and paste, set break points, and add a watch to the following:
x
options[x].value
options[x].checked

I have a form with several textboxes. All of these have AutoPostBack="True".
My problem is that the focus disappears to goodness knows where after each postback. The behaviour I would like to enforce is as follows,
If the user hits the Enter or Tab key after filling in a textbox then the focus should go to the next field on the form (to be explicitly specified in my code).
If the user clicks on textbox X after filling in textbox A then the focus should go to textbox X after postback, even if it is not the next in the list.
In other words, I want the form to behave in the way that most users would intuitively expect.
I have Googled for potential solutions to the loss of focus after postback but the few that I have found were many years old and I am unsure that the advice is still relevant for ASP.NET 4.0. Some of these old solutions also appeared to be invalid for browsers other than IE. What is the current best practice for handling this issue?
BTW, VB.NET solutions are preferred though I will also be happy to accept C# suggestions (which I would run through a code converter). Note that I have a single sub in my code for handling the TextChanged events for all my textboxes. This means that I have to use the following code to work with the textbox that has called the sub.
Dim CurrentTextBox
As
TextBox =
DirectCast(sender,
TextBox)
If addressing the focus problem means that I have to have individual TextChanged event subs for each textbox then so be it, but I prefer the simplicity of my current single sub approach.
I'm trying to figure out how can I control my linkbutton which nests inside my DataItem in the ItemTemplate.What I wish to do is to check something in the server side and according to that, decide whether I wish to alter its visibility to "true" or to keep it hidden. I think that the method which is going to solve it is the ItemCreated, although, I don't happen to know how to control that specific item of mine.
Here is my DataList control:

I have a GridView bound to a SqlDataSource. If the text in a particular column is very long then the Grid view becomes very wide, well off the page. How do I constrain it, if necessary truncating the text displayed? I cannot find the relevant setting in the properties section.
View 1 RepliesI have a question regarding the use of Panel control in a FormView controlled by buttons outside a FormView.
There is nothing found on the internet about it.
Can somebody explain to me what the code is for 2 Panel controls in a FormView with 2 buttons outside of the FormView changing the Views.
And also the code with the buttons insise a FormView.
without binding it to a datalist or something else only thru buttons.
The Panel's are in the edit template but I dont think it doesnt really matter in which template it is.
I tried hours to search for an answer or to code it myself but I even dont get a error message.
The normal way with Panel control without a FormView is easy.

I have a gridview inside a div and everytime i scroll to the bottom rows of gridview, it throws back to the top of the grid.
<div id="divGvIncidentDetail" runat="server" style="overflow:scroll; min-height: 10px; max-height: 250px;" onscroll="SetDivPosition()">
<asp:GridView ID="gvIncidentDetail" runat="server" ...>
</asp:GridView>
</div>
To prevent it, i tried implementing following javascript code by user Sun Rays:
<script type="text/javascript">
window.onload = function () {
var strCook = document.cookie;
if (strCook.indexOf("!~") != 0) {
var intS = strCook.indexOf("!~");
var intE = strCook.indexOf("~!");
var strPos = strCook.substring(intS + 2, intE);
document.getElementById("divGvIncidentDetail").scrollTop = strPos;
}
}
function SetDivPosition() {
var intY = document.getElementById("divGvIncidentDetail").scrollTop;
document.title = intY;
document.cookie = "yPos=!~" + intY + "~!";
}
</script>
I get the following error when i run the code: Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object Am i missing something? or is there any other better solution to maintain the scroll position

View 3 RepliesSuppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.
Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.
How I can I do that in javascript?
This is slightly different to most questions regarding HTML tags in strings - I want to add HTML!
I'm using a WYSIWYG editor which produces some eratic results. What im looking to do is to check the string it produces and check whether there are any sentences that aren't wrapped in a <p></p> tag. Typical strings could be:
Example 1
<p>Hello, this is string 1</p>
But string two doesnt appear to be in a <p> tag.
Example 2
None of this text is in <p> tags.
Example 3
Single line of text, again not in a <p> tag.
Could this be done using a regular expression?
