Web Forms :: Adding A Control Through Code?
Aug 15, 2010
I'm trying to essentially add a dropdownlist control array to a from from the code-behind but I am getting an HttpException error saying that it must be placed inside a form tag with runat=server. How can I do this? This is the code I have right now for it:
DropDownList[] cmbArray = new DropDownList[8];
cmbArray[0] = new DropDownList();
Page.Controls.Add(synthesisSteps[0]);
This is in the Page_Load event. Also I am using .NET 3.5.

I have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.

I'm working in 2008 and cannot find out how to simply add the preload event to the code behind. In 2005 I just simply double clicked on the event in the list and it would set it up for me.

I have a CheckBoxList generated from the code behind file that I want to validate with a CustomValidator.However, I don't succeed in stating the C# function that it has to use, and I can't seem to bind it to the CheckBoxList control.
[Code]....
and then something like:WorkCheckboxValidator.ControlToValidate = WorkScheduleCheckboxList.ToString();

I have a dropdown which i have binded code behind as:
protected void PriorityType()
{
DPriority.Items.Add(new ListItem("--Select--", "0"));
DPriority.Items.Add(new ListItem("High", "1"));
DPriority.Items.Add(new ListItem("Medium", "2"));
DPriority.Items.Add(new ListItem("Low", "3"));
}
It shows the items in gridview correctly but when i insert in database as DPriority.SelectedValue . it does not save the text but the index
Like if i choose High in database it saves as 1 but it should save as text not index.

I was wondering if there was anyway to populate the page with asp.net code like "<asp:Repeater ID="rptProducts" runat="server">MORE_CODE</asp:Repeater>" and then have the server use that code on the page. I'm not sure if i'm making sense. Like writing the asp.net front end code to the page dynamically before the .net engine generates the output html.

I am having issues correctly setting up reference to javascript code to a custom validator.This is my javascript code in the .aspx page.
[Code]....
And here is where I add the Client Validation to the customer validator in the code behind.
[Code]....
The validation is if there is a value present in the first text box then the second text box is required.The page throws an error when the validation should fail, but if I ignore the error the validation works correctly.Do I need to move my javascript to the code behind as well?

Adding an ImageButton to the ImageMap control as a child control. I am developing a map that will be contained some user-defined nodes. The user can click anywhere of the map to add the node to that location. X locations and Y Locations are stored in the database. Initializing the page all stored nodes will be created programmatically. My problem is that the created nodes are invisible. If I replace the ImageMap with a panel control then all dynamically created nodes will be visible but in this situation I cannot capture the X and Y locations.
protected System.Web.UI.WebControls.ImageButton
btn;
protected void Page_Load(object sender,
EventArgs e)
{
btn.ImageUrl = "Images/..."
}
override protected
void OnInit(EventArgs e)
{
btn = new ImageButton();
btn.ID = "btn1";
btn.Style["Position"] =
"Absolute";
btn.Style["Top"] =
"100px";
btn.Style["Left"] =
"100px";
ImageMap1.Controls.Add(btn);//... invisible nodes
// Panel1.Controls.Add(btn);//... visible nodes
base.OnInit(e);
}
So I have one of the following problems:
1. Adding child to the ImageMap Control OR
2. Capturing the mouse X and Y Locations in the panel

I inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:
Overload resolution failed because no accessible 'Add' can be called with these arguments:
'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'.
'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.
I have played around with the code quite a bit and have been researching online, but I'm just drawing a blank here.
I put the class("MyItem") in the "App_Code" folder in a file called "MyItem.vb". The class code is as follows:
[Code]....
The code I have for the sub that is supposed to add the items to the listbox is as follows:

I'm trying to do something that should be very simple, but getting completely stumped on why it's not working.
I have a page that has a few calendar controls, and when the user clicks a date, I want it to toggle the value (in this case it's the "availability" of the date).
I don't want it to post back with every calendar click, so what I'm doing is:
1. During the dayrender event, a Hidden Field gets added to the day. (As it is created, the Hidden Field is added to an array so that it can be retrieved later.)
2. When the user clicks, the value of the Hidden Field is toggled using JavaScript.
3. Once the user is done marking unavailable days, they click a Save button, which gets the values, and saves them to the database.
The Hidden Fields are getting added, and toggling is working just fine. The problem is that when the user clicks the Save button, all the Hidden Fields and their values get cleared, so at the time of the save, it thinks the length of the Hidden Field array is 0.
I think it has something to do with the order in whcih the page is rendered, and the "Save" code executed, but I'm not sure how to fix it. I'm doing something almost identical on another page that works fine - the only difference is that on that page there are no calendar controls, so instead of being added at dayrender, the dynamic controls are added on page load.
If I wanted to add a Hidden Field for each day in a calendar, whose value I can change with Javascript, how do I go about it in a way that I can access the values when clicking a Save button?

I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.

I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.

I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.

I am looking for some advice on how to accomplish something. What I have is a gridview on a page that I want on another page. I would like to show this gridview in a modalpopup.The problem is that the gridview is on a page that is not open and is not likely to be the previous page. I have simply put an iframe inside the modalpopup and loaded the page containing the gridview, however this page is a child page and I get a lot of content from the master page that I do not want. All I want from the page is the gridview.The two options I am considering are putting the gridview in the master page or copying the gridview, and all its events code, to the page that calls the modalpopup.Is there a better way to do this? Or should I just put the gridview in the master page. Can I load a control from a page that isn't open?

Long time programmer just now getting into .NET so There may be something better but I would like to use the Graphics Server Extended Graph (Graphs32.ocx) on my form.
I tried to put it in the Toolbox by going to Tools --> Choose Toolbox Items --> Com Components tab
then check that item and press OK. From what I saw in help files, it should now appear in the Toolbox. Unfortunately, I can't find it anywhere. Did I miss a step in this process? I then tried adding the ocx to the project Bin folder and repeating the steps. Still can't see it. If I can't get it onto the Toolbox, is there another way I could put the control on the form ?
