I m trying to change the img src using the code behind.
A dinamic image that the final user can alter anytime and after this he can send that html content to some email adress.
My trouble is that when I change the image using the code behind the img src doesn't come with html content.
I have a drop down box that is in the edit template of a formview. I want to be able to add a parrameter to the querystring when the drop down selected index is changed.
I tried
Request.QueryString.Add("tabindex", (sender as WebControl).TabIndex.ToString());
But I got an exception saying the collection is readonly.
Here is my markup
<icms_ref:ReferenceDropDownList ReferenceDataManagerProviderName="ROCSQLReferenceDataProvider"
ID="ddlEnquirerHearType" TabIndex="2" runat="server" ReferenceSetName="EnquiryHearType"
AutoPostBack="true" OnSelectedIndexChanged="EnquirerHearType_SelectedIndexChanged"
DataTextField="ShortName" DataValueField="ReferenceId" />
and here is my code behind.
protected void EnquirerHearType_SelectedIndexChanged(object sender, EventArgs e)
{
var pnlEnquiryHearTypeOther = fvEnquiryInformation.FindControl("pnlEnquiryHearTypeOther") as Panel;
pnlEnquiryHearTypeOther.Visible = DdlEnquirerHearType.SelectedValue == ((int)EnquiryHearType.Other).ToString();
ResetTextBox("txtEnquiryHearTypeOther", fvEnquiryInformation);
Request.QueryString.Add("tabindex", (sender as WebControl).TabIndex.ToString());
}
i facing a problem to change the date format at gridview display.
below is my coding:
[code]....
When i run the following code i get an error when gridview changes mode to Edit. stating that you can't change string to decimal!
To get around the occurance i want to disable code when in Edit mode or resolve another way?
GridView1_RowDataBound
For Each row As GridViewRow In GridView1.Rows
Dim cell As TableCell = row.Cells(7)
Dim invoicetotal As Decimal = CDec(cell.Text)
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'm trying to build a web page where the user can send the contents of the web page to someone of their choosing. The email body is html scraped from the website. I have it working, but the the problem is that the image src is relative <img src="/images/filename.jpg"> and I need to make it absolute. What function is the best for me to use on the string that contains my html to make file path absolute in the method I'm trying to create? I tried the following, but am getting error "too many characters in character literal"
reformattedContent.Replace('src="/images/', 'src="http://' + domain + '/images/');
I'm concatenating a string in codebehind to use in a sql select statement.
in aspx
<asp:Label ID="LabelHidden" runat="server" Visible="False"></asp:Label>
SelectCommand="SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)"
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList_Employees" Name="ID"
PropertyName="SelectedValue" Type="Int32" />
<asp:ControlParameter ControlID="LabelHidden" Name="ActivityName"
Type="String" />
</SelectParameters>
in codebehind
foreach (ListItem li in ListBox_Activities.Items)
{
if (li.Selected)
{
queryBuilder += li + "', ";
}
queryBuilder = queryBuilder.Substring(0, queryBuilder.Length - 1);
LabelHidden.Text = queryBuilder;
When i run the code it comes up blank. I did a query trace and it seems to be running as
exec sp_executesql N'SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)',N'@EmployeeID int,@ActivityName nvarchar(50)',@EmployeeID=4,@ActivityName=N'Production Technical Support'', Tools Development'','
with exta "'s
How can i format the queryBuilder string correctly in my code?
I have seen the MVC source code,and I found that the source register the Areas like this:
foreach (Type areaRegistrationType in areaRegistrationTypes)
{
AreaRegistration registration = (AreaRegistration)Activator.CreateInstance(areaRegistrationType);
registration.CreateContextAndRegister(routes, state);
}
so... how can I change the order without change the source code?
Does anyone has an idea on how to change the connection string of the webparts at runtime. i have a multitenant app, and would like to store each accounts users settings in their respective DB's i tried changing the connstring in the webpartsmanager init, and the page load event
Dim myConfiguration As System.Configuration.Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")
at present i'm using like this
If Not IsNothing(ID) AndAlso Not ID = "" AndAlso Not CInt(ID) = 0 Then do something End If
i'd like to add, if it is not string. How?
String is immutable and StringBuilder is mutable. So if I change the value of a string a new memory created with the new value, whereas in StringBuilder it updates its memory location rather than creating a new memory location. So for large concatenation stringBuilders are preffered. But when I create a new String object, a fixed memory is created. And any changes will update its memory location, rather than creating a new memory location.
For e.g.
String s = new String();
s = String.Empty;
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s =string.Concat(s, "test" + i.ToString()); ///This is effecient compared to previous step
}
Now instead of String class I will use a StringBuilder class.
StringBuilder s = new StringBuilder(String.Empty);
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s.append( "test" + i.ToString());
}
I'm struggling once again to get something centered on a page, and fighting with recalcitrant browsers. I can fix the problem for one browser by adding a style. I can fix it for the other browser by NOT adding the style. I can determine which browser I'm using. If I can change the properties of a div in the code behind, I can create a class and apply it to the div as needed. I added an id to the class:
<div id="alignLV2" runat="server">
but in the code behind, alignLV2 doesn't seem to have a class property. Is there a way to add a class or change the style?
I'm trying to to display the first 50 characters of text from a database field.
I thought I could do it something like this: <%# Eval("BodyTxt").ToString().Trim("50")) %> but it doesn't work.
I've also tried this: <%# Trim(Eval("BodyTxt")) %> although I never expected that to work.

I created a new project in VS2010. It automaticly creates masterpages and other stuff.
In the login page i create a connection with my local database. To test my login-routine i want to change te text of a label.
I wanna do this with behind code (C#).
But i continue get errors that the refered label doesn't exist: Error 1 The name 'Labeltest1' does not exist in the current context l:DocumentenVisual Studio 2010WebSitesWebSite1AccountLogin.aspx.cs 46 13 l:...WebSite1
I tryed different solutions, but nothing .
[Code]....
protected void Page_Load(object sender, EventArgs e)
{
TextBox tb = new TextBox();
tb.TextChanged += Test;
}
private void Test(object sender, System.EventArgs e)
{
Label2.Text = "ok";

I have the following code in visual studio 2010:
TextBox1.Text = My.Computer.FileSystem.ReadAllText("C:UsersBabyDesktopSimulator websiteResourcesTextFile.txt")
It reads the text in the textfile and displays it in the textbox. However, this link only works on my computer. How do I change the code so that when published online, it still works on anybody's PC? I think i need to refer to a relative path, but do not know how this should be done.

I have two DropDownLists; DropDownListStart displays the hours 09:00 - 19:00 and DropDownListStop displays 10:00 - 20:00. When the user chooses one of the hours in DropDownListStart I want the program to adjust what's shown in DropDownListStop so that the first hour shown is one hour after the hour chosen in DropDownListStart. How can I do that in code behind (c#)? An example: if the user choses 13:00 in DropDownListStart I want DropDownListStop to display only 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00.
View 12 RepliesI have a page currently setup to upload 1 image at a time, it uploaded the image, then creates a thumbnail for that image in the same directory. Client needs / wants to be able to upload a few more images at the same time. So i would like to see if i can use the existing code that works, but setup to upload a few more images and process them all to create the thumbnails.
I currently have a page that allows them to upload 5 images at a time and that works fine, but its just simple uploading the images, nothing else is happening at that moment.

I am trying to get my head around the ASP timer control. What I am trying to achieve is to get a page to reload every 60 seconds but change the url querystring everytime between 3 values
i.e. scroll through
server/page.aspx?value=1
server/page.aspx?value=2
server/page.aspx?value=3
how I have though to do this is to use ASP code to grab the querystring value, and then create the next url. But I am having trouble passing that newly created url to a refresh control. im guessing HTML meta refresh is out of the question as I am using a variable. So from what I can see my option is to use the ASP timer control to count down (after the page has loaded) and after 60seconds load the next url.
