New Post: Using Asp.Net 2 without Asp.Net 1.1 loaded

adrianaitken — Sun, 24 Aug 2008 14:59:34 GMT

Worked it out - the Regsiter directive should just say '... Assembly=MetaBuilders.Webcontrols' and not specify the individual DLL as in his Asp.Net 1.1 controls.

New Post: Using Asp.Net 2 without Asp.Net 1.1 loaded

adrianaitken — Sun, 24 Aug 2008 13:22:35 GMT

Hi all, even using the samples in the Help file, if I have only Asp.Net 2 (+sp1) installed, I get the 'Could not load file or assembly 'Metabuilders.webcontrols.dialogwindow' or one of its dependancies' error.
I was under the impression this is a Asp.Net 2 app now that I've just downloaded. Do I also need Asp.Net 1.1 installed ?

If someone could answer this I'd be grateful.

New Post: How To Use Control Inside DetailsView

johnywhy — Tue, 19 Aug 2008 00:19:16 GMT

Apparently, the comboBox (and maybe other controls of this collection) will not behave properly in a DetailsView in the following scenario. I'm no expert on this, so maybe else will see my mistake.

You create a details view bound to a dataSource, enable editing, and convert one field into a template. Then you add a comboBox to the editItem template, and bind that comboBox to a different dataSource.

Then, to bind the comboBox's text value to the current record, you add the following attribute to the asp control. This attribute can be copied from the default textBox that visual studio created when you converted the field into a template:

Text='<%# Bind("Region") %>'

So the resulting script will look like:

<mb:ComboBox ID="ComboBox2" runat="server" Text='<%# Bind("Region") %>' DataSourceID="SqlDataSource1"
DataTextField="Region" DataValueField="Region">
</mb:ComboBox>

When you run the page, and click "Edit", you'll get an error something like "There is no source code available for the current location" in debug mode, or "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

The solution I suggest is the following:

Remove the following line from the combobox:

Text='<%# Bind("Region") %>'

Next, add the following Prerender event to the DetailsView:

protected void DetailsView1_PreRender(object sender, EventArgs e)
    {
        if (DetailsView1.CurrentMode == DetailsViewMode.Edit)
        {
            ComboBox boxRegion = DetailsView1.FindControl("ComboBox1");
            boxRegion.Text=     // here's where you have to get the bound value of this field in the details view
        }

    }

I'll leave it to someone else to fill in the missing bit of code above.

The purpose is to use code to load the current value of the field into the comboBox when the user switches to edit mode.

Three questions:

is it possible to use the comboBox as a databound control in a detailsView template field without any custom event code?
if not, what should the missing code above look like?
would it be possible, rather than writing to the PreRender event, to write a custom function to replace the following?

Text='<%# Bind("Region") %>'

New Post: MetaBuilder Help file - No content ?

aychung — Wed, 13 Aug 2008 13:59:14 GMT

Hi,

I hope this is the right place that I can post this issue.

I just downloaded the MetaBuilders WebControls to use Combo Box control. When I open the help file

MetaBuilders WebControls.chm

, it only shows the left panel with index/contents/search tabs, but on the right panel, it only says

Navigation to the webpage was canceled

Is the url to the help context gone wrong or is the server down?
Pls help me!! I really want to use that combo contols and don't know how to start without help context.

Do anybody have any sample that I can use until the help gets fixed, pls?
I am using ASP.Net with VS2008.

Thanks,

New Post: DialogWindow on Asp.Net 1.1

adrianaitken — Mon, 30 Jun 2008 14:36:48 GMT

Hi, does anyone have working code on how to call the DialogWindow from inside code. Basically my website has a autopostback on a listbox, takes the item, does 'stuff; to it and then needs an inputbox displayed.
I have tried to write out javascript by looking at the source code for the online sample which shows a hyperlink version. However I get object not referenced and other errors. I can successfully get it running if I put a button on screen but that is not intuitive for endusers.

Any help ?

Hi, I'm trying to use the webcontrol "combobox" in my project but there are two problems for me :

If you know some properties or settings to change in my project please email or answer me asap please.

Commented Issue: JS error in SelectorField

DarthRob — Sun, 22 Jun 2008 20:45:36 GMT

Hi,

I've placed SelectorField into my GridView to have a RadioButton column there.
<mb:SelectorField SelectionMode="Single" AutoPostBack="false" />
When my page loads IE reports a JS error:
Line: 5
Char: 19
Error: 'MetaBuilders_SelectorField_CheckAllBoxes' is undefined
Code: 0
URL: (mine)

How to fix it ?
I looked into the JS file, it seems like this variable/array was not defined anywhere...

Thanks,

Slava
Comments: ** Comment from web user: DarthRob **

For me, this error occurs when the GridView that contains the SelectorField is not Visible. In this case, MetaBuilders_SelectorField_CheckAllBoxes is undeclared. To test for an undeclared JavaScript variable, you could use typeof(). In "SelectorFieldScript.js" change the first function so that it looks like this:

New Post: How to get value of radio button using GlobalRadioButton

DistortionJunky — Wed, 18 Jun 2008 02:56:16 GMT

My solution has been to add a hidden label control next to each radio button, bind the value to the label, and then access the related label text when a radio button is selected. If there's a better solution, please feel free to chip in.

New Post: How to get value of radio button using GlobalRadioButton

DistortionJunky — Wed, 18 Jun 2008 01:58:27 GMT

I'm trying to use the GlobalRadioButton control within a repeater. All seems to be working OK except there does not seem to be a way to access the value field of the radio button. I can access a text field, but that's no good since I don't want to display the data I need to retrieve. Any help would be appreciated.

NEW POST: ResizeMonitor on first page load

EduardoMArtins — Fri, 06 Jun 2008 19:36:16 GMT

Is there a way to have the ResizeMonitor component return the client screen dimensions on the initial page load, without the need for the user to resize the browser window? I guess I would need to raise the resize event, but I am pretty new to VB and don't know how to do that... Any help will be greatly appreciated!

Thanks!

Patch Uploaded

ewsachse — Wed, 28 May 2008 19:10:30 GMT

ewsachse has uploaded a patch.

Description:
This is a fix for 9182 - 'undefined' is null or not an object

The source of the erroris in the MetaBuilders_DialogWindow_DoDialogPostBack function in the DialogWindowBaseScript.js file. It was not checking if the result was undefined. See below.

broken code:
if ( result == null) {
result = info.DefaultValue;
break;
}

fixed code:
if ( result == null || result == undefined) {
result = info.DefaultValue;
break;
}

COMMENTED ISSUE: 'undefined' is null or not an object

ewsachse — Wed, 28 May 2008 14:29:03 GMT

I got this error when testing the OpenDialogButton in IE7 when I try to close the dialog using the IE7 tab close button.
The sample in http://www.metabuilders.com/Tools/DialogWindow.aspx also produces the same error in IE7, open a "poorly" designed dialog box, then close the tab/window via its close button.
Comments: ** Comment from web user: ewsachse **

I found the source of the error in the MetaBuilders_DialogWindow_DoDialogPostBack function in the DialogWindowBaseScript.js file. It was not checking if the result was undefined. See below.

broken code:
if ( result == null) {
result = info.DefaultValue;
break;
}

fixed code:
if ( result == null || result == undefined) {
result = info.DefaultValue;
break;
}

I also attached an updated DialogWindowBaseScript.js if you want to get the source and rebuild the project with this change.

NEW POST: Selectorfield allowselect cannot be false???

bhastings316 — Tue, 20 May 2008 14:36:55 GMT

I'm am using Metbuilders Selectorfield within a gridview control and everything was working quite happily. As I am short of screen space I decided to hide the header of the gridview, this caused a script error 'Metbuilders_selectorfield_checkallboxes is undefined.

I showed the header and all was well. I then decided to set allowselect all to false again producing exactly the same error. It obviously isn't happy when the Select all check box cannot be seen but I can't understand why.

Has anyone else come across this? Is it a bug in the control?

NEW POST: Please - can anyone share a SelectorField example?

blankers — Wed, 14 May 2008 02:54:16 GMT

I have the selectorField displaying correctly in a GridView - but I'm beating my head against the wall trying to figure out how to retrieve the selected checkboxes in my code-behind. Has anyone seen any documented examples of how to get this working? Can anyone please share a working example of this??

Thanks,

NEW POST: SelectorField control not available on ASPX page?

blankers — Wed, 14 May 2008 00:22:22 GMT

finally figured it out - SelectorField belongs at the column level, not within a TemplateField like most of the other MetaBuilder.WebControls...

NEW POST: SelectorField control not available on ASPX page?

blankers — Sat, 10 May 2008 23:35:34 GMT

Hello,
I'm trying to use the SelectorField in an .aspx page and can't figure out how to implement it in my gridview's TemplateField column. After registering the assembly, I can see most of the MetaBuilders.WebControls in IntelliSense on the aspx page, but I can't see any of the controls that are inherited from System.Web.UI.WebControls.DataControlField (like SelectorField, BooleanField and LookupField). (I am able to instantiate a SelectorField within my code-behind file but I would really like to be able to use SelectorField in the .aspx page. )

Here is my code:

(web.config)
          <add tagPrefix="mb" namespace="MetaBuilders.WebControls" assembly="MetaBuilders.WebControls"/>

(aspx page)
    <asp:GridView ID="GridView1" runat="server" >
        <Columns>
            <asp:BoundField DataField="BlacklistUrlId" HeaderText="Id" SortExpression="Id"></asp:BoundField>
            <asp:TemplateField>
                <ItemTemplate>
                    <mb:SelectorField SelectionMode="Multiple" AutoPostBack="false" Visible="true"/>
                </ItemTemplate>
            </asp:TemplateField>

Can anyone please tell me if there is something I'm missing about how to use this control? An example page would be extremely helpful!

Many thanks,

Terry

CREATED ISSUE: XHTML compliance - all attributes should be lower case

robh — Sat, 03 May 2008 19:41:33 GMT

According to http://www.w3.org/TR/xhtml1/#h-4.2 , all attributes should render lower case. But the RolloverImage control renders its onmouseover and onmouseout in title case. Example:

<a id="header1_RollOverLink4" href="Invest.aspx"
OnMouseOver="RollOverLink_swapImage('header1_RollOverLink4_img','','/images/invest_r.png',1);"
OnMouseOut="RollOverLink_swapImgRestore();">

It should be like this:

<a id="header1_RollOverLink4" href="Invest.aspx"
onmouseover="RollOverLink_swapImage('header1_RollOverLink4_img','','/images/invest_r.png',1);"
onmouseout="RollOverLink_swapImgRestore();">

Easy fix, right?
