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:
[code]....
I have created a custom control and I intended to assign some attributes which is not necessary to implament.
I also assign default value for them but I am getting System.NullReferenceException error.
Here is my CC's attibute code;
public class ApplicationModule2010 : CompositeControl
{
[DefaultValue(true)]
public bool AppFormOnLine { get { return (bool)ViewState["AppFormOnLine"]; } set { ViewState["AppFormOnLine"] = value; } }
...
also ı have written the below code for another attribute but its default value doesn't work as well;
[DefaultValue("Application is Offline ! Define an offline Text insted of this text !<br/><br/>TugberkUgurlu.Com")]
public string OfflineText { get { return (string)ViewState["OfflineText"]; } set { ViewState["OfflineText"] = value; } }
What am I missing here ?
I want to add a custom attribute to an asp.net RadioButton called Key which I'm using client-side for an ajax request.
What I'm finding is that my aspx markup which is the following:
<asp:RadioButton ID="rdoPost" GroupName=PreferredContactMethod" value="Post" onclick="DoStuff(this)" runat="server" />
gets rendered in the page as<span Key="ContactMethod">
<input id="rdoPost" type="radio" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
</span>
whereas I'd expected (and hoped) to get the following
<input id="rdoPost" type="radio" Key="ContactMethod" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
I've tried the same thing with an asp TextBox control and it works exactly as I'd expect simply adding the Key="myKey" attribute to the <input type="text"/> element.Is there a way around this with the standard RadioButton control, or will I have to inherit from the standard one to achieve the markup I'm wanting? Currently I'm using these attributes in JavaScript in the following way:
var key = rdoPost.Key;
public class CustCtl : WebControl
{
protected override System.Web.UI.HtmlTextWriterTag TagKey
{
get
{
return HtmlTextWriterTag.Div;
}
}
}
With this bare bones control, it would render the root element as a Div tag. But how can I add attributes to that root HTML element that this control will render .
I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I have a question regarding the GridView and the Control Designer of it.
I've made a composite control inherited of the GridView. I would like to make some new created BoundField controls available in the designer of the GridView control? So that I can select the custom BoundField control from the Available fields list.
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
View 8 RepliesI need to develop control (template or user) which must have subtags with some items.
For example :

</SomeControl>

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>

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