Adding a custom control to the SharePoint 2010 Team Site Wiki Page Template ( wkpstd.aspx ) programm

  
Topic This is maybe my last post about the Team Site Wiki Page customization with the aim of exceeding its limitations. This time we are going to customize the unique template ( wkpstd.aspx) by replacing the control that renders the editable content by a custom one. In this post example, we will take advantage of the use of this custom control to render not editable additional contents, for instance, a header and a footer that could be the same for a specific Wiki Page Library. Of course, we are not going to really customize the template, but we are going to use a delegate control to replace the control at runtime. Here are the screen shots of the result: We can see a non editable Header and Footer on the Team Site Wiki Page In edit mode these additional contents are not rendered, but we can add new content as usual And of course, after having saved the page, the new content is rendered wtih the non editable Header and Footer. Steps required   If you look at the Team Site Wiki Page template, wkpstd.aspx, you can see the control that is rendering the editable content/ <SharePoint:EmbeddedFormField ID="WikiField" FieldName="WikiField" ControlMode="Display" runat="server" /> We are first going to create a custom EmbeddedFormField control Then, we are going to use a delegate control to replace the native EmbeddedFor

How to Access Parent Page (.aspx) control (IDs) from its child User Control (.ascx)

  
I have a parent .aspx page that has a asp:panel control in it, and this parent .aspx is also referencing a user control that I registered in that .aspx. Lets just call it usercontrolA.ascx for this post.The user control has a radiobuttonlist itself.Based on a selection from the radiotbuttonlist in the user control, I want to be able to hide the asp:panel in my .aspx (parent) but unfortunately I cant' get it to work:parentPanel.visible = true;  <<< I trried this in usercontrolA.ascx.csBut the user control doesn't know about the panel in the parent .aspxSo do I need to expose that somehow from the parent so that I can access it from the code behind of the child .ascx?  How?

Adding a server control on aspx page does not add events in aspx.designer.vb file

  

Hi,

I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.

I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ? Please advise.

Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.

Please advise if any settings have to be changed.

Thanks,

Arunesan


How to access child(.ascx) page control from parent page(.aspx) javascript

  

I have functionality to select All check boxes on grid rows.

Child User control is having grid with checkbox to select all rows of grid. I want to select individual cell html from each row when I select all rows when checkbox 'select all' is clicked and place it into textbox which is in Parent page.

This textbox can only be in parent page.

So i need to call child(.ascx) page control from parent page(.aspx) using javascript as follows.

function CheckUncheckChildren(event)
    {
        document
        debugger;
        var childChkBoxes = document.getElementById('<%=gvUserDetails.ClientID %>').getElementsByTagName("input");
        var childChkBoxCount = childChkBoxes.length;
        var evtelem = (isIE())?event.srcElement:event.currentTarget;
        if(evtelem.checked == true)
        {
            for(var i = 0; i<childChkBoxCount; i++)
            {   
    &nbs

User Control not accessing the value of the properties send to it from the aspx page.

  

I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as

<ContentTemplate>

<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>

</ContentTemplate>

but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong


the problem is eval is not passing the value to usercont

Adding .aspx page to existing web site

  

Hello,

I have a running ASP.NET web site. There is following problem with one of the forms:

One part of submitted data is added to database after "submit" is clicked. (to "table1")

Another part is lost (not added to "table2", and no files uploaded)



I have no source code of that project.

So, because I cant edit existing page, I came to a decision to add new .aspx page to a running application with same functions as existing one.

How can I do that? Or maybe you can recommend some other solution.

Thanks, Alex. 


How To : Add a ListBox Win form control to a asp.net .aspx page

  

Here is my requirement:

Do File upload without fileupload asp.net control, instead do following:

1) 'drag and drop' of file (attachment) from windows explorer to .aspx page

2) 'Copy / Paste'  - in a .aspx


What I can think of is doing it by creating a 'Windows ListBox control'.dll and calling it in aspx page with

<object></object>,


Is there any better solution out there?
