I want my User Control to be able to have Literal Content inside of it. For Example:
<fc:Text runat="server">Please enter your login information:</fc:Text>
Currently the code for my user control is:
<ParseChildren(True, "Content")> _
Partial Public Class ctrFormText
Inherits UserControl

I try to mak a custom textbox. Something pretty easy to do but I can't figure out one thing. When I write my textbox in designmode I have this <custom:Textbox runat="server" ID="Textbox1">Test</custom:Textbox> The problem is The textbox is a webcontrol I added to my class [Parsechildren(false)] like this [Parsechildren(false)]
public class Textbox : WebControl
{
}
now the problem is I want to able to write the Text from the textbox between the beginningtag and andingtag but I want to disable every other control in designmode. When I add < between the tags then you can see you can write all tags between it. disable all controls except literal between the tage in designmode?
I need to develop control (template or user) which must have subtags with some items.
For example :
<SomeControl runat="server" id="scTest">
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
</SomeControl>
This control may contain some other web server controls such as GridView.I need explanation of experienced developers, how to do that - take me to the right way
I take a user control file. I put this
[Code].....
For example:
<uc:AdmiralAckbar runat="server" id="myCustomControl">
<Warning SomeAttribute="It's A Trap">
My Data
</Warning>
</uc:AdmiralAckbar>
I'm not sure how to add SomeAttribute.
Code without the attribute is:

I'm trying to have an asp.net custom control with a field like:
<ErrorTemplate>
<h1>Error</h1>
<p>Blue wizard shot the food</p>
</ErrorTemplate>
What I want to end up with is:
<h1>Error</h1><p>Blue wizard shot the food</p> in a string in my codebehind.
At the moment, the process I use to get this data out of the template is:
First this gets instantiated into a placeholder by my code:
ErrorTemplate.InstantiateIn(errorPHolder);
which is an asp.net placeholder control - it has to be instantiated into something which can support controls.
What I then want to do is add this to my page using JQuery and a variable, like this:
string script = "var Errortemplate = " + errorPHolder.ToString() + ";";
scriptmanager.register(script); // pseudocode
so the result would be, on my page:
var Errortemplate = '<h1>Error</h1><p>Blue wizard shot the food</p>';
Then I can use JQuery to do someDiv.html(Errortemplate);
Finally resulting in whatever they put in <ErrorTemplate> appearing on the page
Because I'm using JQuery it might be possible to do this a different way, such as adding the placeholder to the page into a hidden div and using JQuery to copy the values out.
I currently have:
<uc:MyControl ...>
<Template>
</Template>
</uc:Mycontrol>
I would like
<uc:MyControl ...>
<FishBiscuit>
html
</FishBiscuit>
<FishBiscuit>
html
</FishBiscuit>
<FishBiscuit>
html
</FishBiscuit>
<FishBiscuit>
html
</FishBiscuit>
However I'm not sure if it's possible, or how to wire it up if it is.
Is there any HTML tag that will wrap my text without changing its style at all? I've tried <pre> but that makes it look weird. I need this because I'm trying to include Literal content within a System.Web.UI.ControlCollection.
View 1 RepliesI would like to set the one template for edit/insert and view in my custom FormView control . But i got these odd exception Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.Table'.
public class CustomFormView : FormView

in the first step , I created the new user control and added a formview ("FV")
public partial class Form : UserControl
{
private IBindableTemplate _template = null;
[PersistenceMode(PersistenceMode.InnerProperty),
TemplateContainer(typeof(FormView), System.ComponentModel.BindingDirection.TwoWay)]
public IBindableTemplate FormTemplate { set;get }
protected void Page_Init()
{
if (FormTemplate != null)
{
FV.InsertItemTemplate = FV.EditItemTemplate = FormTemplate;
if (!IsPostBack) FormTemplate.InstantiateIn(FV);
}
}
}
Now , I want to convert this user control to web control.

This control when used on any aspx page will popup the control placed inside the template "divContent" as modalpopup.

The problem I am facing is that the modalpopup extennder is not coming up as a popup.
I'm creating an ASP.NET Control which has a property collection for Columns which the user can edit in the Property Collection Editor..
In most circumstances this works fine, the collection can be edited in the designer and the appropriate tags are added inside the control in the ASPX file.
It works fine when
My control is added to the form
[Code]....
My control is added inside an Update Panel
[Code]....
[Code]....
However, if My control is inside a Content Placeholder which is inside an Update Panel, it fails to work as it should. In this scenario, when the Columns collection is edited in the designer, if you then switch back to Source view, the Columns collection is emptied. I have to save the aspx page before switching back to Source view for the changes to be kept.

how to get around this problem? Is there something I may have missed?

I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control.

When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?

I'm using a literal to display some javascript on a product page control. Basically what I'm doing is in my code behind I'm declaring a new stringbuilder, writing the script while inserting some dynamic variables to populate the script then setting the literal text to the stringbuilder.

System.Text.StringBuilder sb = new System.Text.StringBuilder();
//loop through items in the collection
for (int i = 0; i < _prod.ActiveProductItemCollection.Count; i++)
{
sb.Append("<script type='text/javascript'>");
//add +1 to each item
