Currently working on a project that will allow users to change the font of a richtextbox control. I gathered all the system fonts on form load into a combobox control. I am having difficulty having the richtextbox control's text change with the combobox control value is changed.
View 2 RepliesI have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.
View 3 RepliesSynopsis: I have a AJAX enabled ASP.Net application, the purpose of which is to allow users to ad hoc drill an engineering database. The application UI is divided into three sections, Filtering, Column Selection, and Results. The filtering section (implemented as a user web control) uses a PlaceHolder control, to which I allow addition and removal of individual Filter user controls.
All of that works well. The Filter user control essentially consists of three ComboBox controls with SqlDataSources bound to each of those ComboBoxes, and a TextBox to enter in a value. The first ComboBox, once a value is selected in its list, passes the SelectedValue to the SqlDataSource of the next ComboBox, which uses that value as a Select Parameter so the DataSource can fill out the ListItems of the next ComboBox. So simply, the results of the previous one cascade to the next.
Again, all this worked well. But one of the requirements was to allow storage of these queries the customer comes up with, allowing them to reload the query at a later time to run again.
I implemented that by writing a simple set of container classes, Filter, Column, and Query, where Query has public arrays of Filters and Columns. I serialize that simple Query object, then store it as XML in my database. To reload it, I de-serialize the xml, and rebuild the Query object, which I then use in turn to rebuild the Filters and Columns.
And that is the problem. I am rebuilding the query, and I think I am setting up the Filters correctly. Everything reloads on the page, just as I had saved it. But then when I try to use the query, I get the error
System.ArgumentOutOfRangeException 'ComboBox' has a SelectedIndex which is invalid because it does not exist in the list of items. Parameter name: value
I believe the problem is that the SelectedIndex is attempting to set the index for the ComboBox before the DataBind occurs during a postback.What is curious about this is if I hadn't tried to load and initialize these controls myself and just added a bunch of fliters setting ComboBoxes as I go, it has no problem maintaining the SelectedIndex, the list of values in the ComboBoxes and so on during a postback. I don't believe in that case it is even doing a DataBind for those controls.
I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.

<ajaxToolkit:ComboBox ID="cmbAddressAlias" runat="server" DropDownStyle="Simple" AutoCompleteMode="Suggest" CaseSensitive="false" AutoPostBack="true" RenderMode="Inline" Width="170px" CssClass="cmbProvince" OnSelectedIndexChanged="cmbAddressAlias_SelectedIndexChanged"> </ajaxToolkit:ComboBox>
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).
I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.
In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.
I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts.
<div>
<%
string fontName = "Segoe Script"; //Change Font here
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100);
System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp);
[Code]...
If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.
Update:
Based on this question here I was able to get it working by using a PrivateFontCollection() and loading the font file like so.
<div>
<%
string TypeFaceName = "Segoe Script";
System.Drawing.Text.PrivateFontCollection fnts = new System.Drawing.Text.PrivateFontCollection();

I have an ASP.NET page that I need to have access the local file system. It's an intranet. I need to download a zip file and an executable to a temp location and then run the executable.
Then afterwards, I need to delete the contents via an ASP.NET page.
Is there any way to access the local file system? Generally, I would think this would cause a security concern, but I've seen posts about Silverlight being able to access it.

I have a WYSIWYG textarea (CKeditor) in my CMS.Most of the users write the article first in a word document and then paste it in the textarea.
Sometimes they paste as plain text, but sometimes not. And sometimes the articles final result is a mess because of the HTML that Word generates.
I have problems specially with the fonts, people change font face in Word and when they paste text in the textarea, the font face used in Word remains (seems that Word uses the <font> tag.

View 2 RepliesWe are using ASP.NET ReportViewer Control to render rdl files. In the rdl files we have set the font to "Century Gothic" and in preview mode it renders the fonts nicely. However - when it gets rendered on browser we see the fonts defaulted to "Times New Roman".
I tried couple of things without success:
1. Setting the font family of the page ()
2. Setting the FontNames of the ReportViewer control
One more thing is I don't see Century Gothic in the list of available fonts in the HTML Editor inside Visual Studio 2010. Do I need to add them somewhere?

View 1 RepliesI am creating some simple asp.net web forms. All these forms need to have is a simple message that indicates the system is unavailable.

View 1 Repliesthis is an extremely frustrating situation. We have just upgraded to Visual Studio 2010, and very nice it is, except for when it won't do something really simple, like Publish your ASP.NET Web Application to a folder on your desktop.For some unearthly reason, what used to work flawlessly in 2008 is now generating an error: It stops Publishing, after successfully Building, saying:Error: Copying file ImagesProfile32_32.JPG to objx64ReleasePackagePackageTmpImagesProlfile32_32.JPG failed. Could not find file 'ImagesCelebrityProfileImages32_32.JPG'.The problem is that there isn't any reference to that file in the project code (in the database, yes, but not in the code itself), and we don't want to store such images with the project (and they're not).Why (and how) has it suddenly decided that this unreferenced image (and presumably more if I get it to move past this one) is suddenly necessary to run the project? How can I stop this from happening?
