I don't know if I'm on the right track here, but this is what I know about it.
Example:
<p>Oligarchy (from <a href="/wiki/Greek_language" title="Greek language">Greek</a> <span xml:lang="grc" lang="grc">ὀλιγαρχία</span> (oligarkhía); from ὀλίγος (olígos), meaning "a few", and ἄρχω (archo), meaning "to rule or to command")<sup id="cite_ref-0" class="reference"><a href="#cite_note-0"><span>[</span>1<span>]</span></a></sup><sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span>[</span>2<span>]</span></a></sup><sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span>[</span>3<span>]</span></a></sup> is a form of <a href="/wiki/Power_structure" title="Power structure">power structure</a> in which <a href="/wiki/Political_power" title="Political power" class="mw-redirect">power</a> effectively rests with a small number of people. These people could be distinguished by royalty, wealth, family ties, education, corporate, or military control. Such states are often controlled by a few prominent families who pass their influence from one generation to the next.</p>
To the best of my knowledge, the example is created in something like ckEditor, in which the content is composed online, and selected words are highlighted, and a custom control button is clicked to wrap the word with a HTML tag, that provides a pre-selected function or formatting feature.
However, it is done in Javascript, inside the editor during creation. To automatically pick out words, and wrap them in HTML tags, it can be done server side, in which you would have to iterate through the words, find the start and stop of the word position number, and replace the word with an HTML tag wrapped version of the word.
If you need to do it on the server side with raw text, you could check for the word, and do a replace.
if (string.contains("raw word") {
string.replace("raw word", "<a href="word.aspx">raw word</a>)
}

thanks jkirkerx, this is on the right track- the search and replace stuff I would do on the server as you suggest- the problem is, what do you put as the href? If I wanted to redirect to another aspx page, it would be easy- but what I really need to do here is to return some data from the server based on what the user has clicked.
e.g. supposing in my html, I had this
<a href="#" onclick="myFunction('click this')">click this</a>
then 'click this' would appear as a link in the html, and it would call javascript myFunction, sending in the parameter 'click this'.
I then need to go back to the server (maybe using Ajax??) and get some data, which then needs to be displayed on another container in the same webform, i.e NOT in the container hosting the html file from where it was clicked.
What would the javascript call be?
Just to clarify- I have an asp.net webform which has a container (iFrame or Literal maybe- doesn't matter), which shows the contents of an Html file. The user clicks on the link in the html file, and it has to show some other data *in another container* on the web form.
thanks so far...

I would use a span tag because it's inline, and won't change the format of the paragraph text. Many buttons just use a span tag for formatting, and are backed by Jquery or Javascript.

Then in JQuery, you add a bind to the class for the click event, pick up the click, get the word, transmit it via $.Ajax to the Web Service, get a response back, figure out what to do.
[Code]: the code is just for conveying the concept, it does not work.
$(document).ready(function () {
initiateBinding();
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
});
function EndRequestHandler(sender, args) {
initiateBinding();
}
function initiateBinding() {
$('.specialWord').click(function () {
var theWord = $(this).html();
var newPage = runWebService(theWord);
window.location = newPage
$(this).empty();
$(this).appendTo("new text");
return false;
});
}
function runWebService(theWord) {
[edit]: window.location = "newpage.aspx";
return newPage;
[3rd edit] take the response, and populate the container using .empty() .appendTo(" la la la"") to the new container.
var newText = objB.newText;
$('newContainer).empty();
$(newText).delay(250).appendTo($('newContainer'));
}
Like I said, just an idea of one way to do it on the client side, with web services on the server side to make decisions.

Error must be here.
You have defined two values for this dropdown - Male & Female.
Based on the error, your datasource field "Gender" at some time has any other value than above two. May be empty! Check what all values are coming.

Hi All,
let's suppose
DataSet ds = new DataSet();
ds.Tables.Add(datatable1)
ds.Tables.Add(datatable2);
Repeater1.DataSource = ds;
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:GridView ID="GridView1" runat=server DataSource="?????" AutoGenerateColumns=true >
</asp:GridView>
</ItemTemplate>
</asp:Repeater>
then what would be the DataSource="?????" in gridview.
Thanks,

zeeShan anSari wrote: Repeater1.DataSource = ds;
Is incorrect. If you have a System.Data.DataSet with multiple tables as a datasource, you must specify which table to bind to the control.
Either:
Repeater1.datasource = datatable1
Repeater1.datasource = ds.Tables[0]
Same thing for GridView too.
GridView1.datasource = datatable1
GridView1.datasource = ds.Tables[0]
Details here:
MSDN: Repeater.DataSource Property [^]
MSDN: BaseDataBoundControl.DataSource Property [^]

I don't think so.
should:
DataSource=Repeater1.DataSource
|
|
|
|

???

DataSource connect Database ,
Not table.
|
|
|
|

put ul li in it Repeater,
that can Meet your needs！You try!
|
|
|
|
|
you can't set to table for repeater datasource, set it as one, or if you need each of them, use view in sql database, or use union linq method, that get it in one source!
like this:
var ds = (table1)Union(table2).ToList();
repeater1.DataSource = ds;

Hi,
I have included a radiobutton on a gridview using HTML control. I tried getting the index of the row selected by the radio button, but I can't figure out how. I tried using the Request.Form["RadiobuttonName"] but it gives me the value on the cell not the row index. Here is the code When I click the button to retrieve the value.
protected void btnSelect_Click(object sender, EventArgs e)
{
string selectedValue = Request.Form["radSelect"];
int index = Convert.ToInt32(Request.Form["radSelect"]);
}
And here is .aspx page
<asp:GridView ID="grdAll" runat="server" OnRowCommand="MPS_Selected" AutoGenerateColumns="false" OnRowDataBound = "grd_rowdatabound">
<Columns>
<asp:BoundField DataField="ID" HeaderText = "" Visible="false" />
<asp:BoundField DataField="Name" HeaderText = "MPS Account Name" />
<asp:BoundField DataField="Industry" HeaderText = "Industry" />
<asp:BoundField DataField="SubIndustry" HeaderText = "Sub-Industry" />
<asp:BoundField DataField="Geo" HeaderText = "Geo" />
<asp:BoundField DataField="LocType" HeaderText = "Location" />
<%--<asp:buttonfield buttontype="Button" commandname="Select" headertext="" text="Select"/>--%>
<asp:TemplateField HeaderText="Select One">
<ItemTemplate>
<input id="rdSelect" name= "radSelect" type="radio" value='<%# Eval("ID") %>' />
<%--<asp:RadioButton ID = "rdSelect" runat="server" onclick = "RadioCheck(this)" />
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%#Eval("ID")%>' />--%>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Any help will do.
Thanks!

What you have given is not a server side control.
<input id="rdSelect" name= "radSelect" type="radio" value='<%# Eval("ID") %>' /> is a client side html control.
2 things:
1. Convert it into server control using runat="server" to access it on server side.
2. In button select, loop through all the rows of grid, use FindControl to find radiobutton control. See if it is selected, if so use the row and it's values
Again, using a radiobutton in gridview is little tricky and needs extra effort to group them together so that only one can be selected at a time. If you face issue, just look for article/question on it on this website itself (shared before with lots of users)

Thanks for the reply. I tried using literal, but I am getting an error Quote: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
in this line
output.Text = string.Format(@"<input id=""RowIndex{0}"" type=""radio"" name=""radSelect"" value=""{0}"" checked=""checked"" />");

You forgot to mention the string to be replaced in {0}
Something like:
string.Format("Hi {0}", "there!");

Actually im getting error when the below code is executed from unit test project...
where import is an xml file in the below code..
XmlTextReader importReader= new XmlTextReader(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Importcontent/import"));
the above code is present in one of the methods in different project(class library) which is used in test method in the unit test project
where as the above path is present in web project.
and the value of the
System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Importcontent/import")
is null..ie unable to get the complete path of the file i guess bcos the hostingenvironment is not running(web project)
The above code is working fine when running from the webproject ie it returns the exact path.
whereas returning null value when running from test project.
please let me know how to fetch the file path(where file is present in web project) when running from test project.
|
|
|
|
|
Either you need to copy the file in bin/root folder of your test project to access OR give an absolute path of the file to access.

I have some objects I should add to ASP.NET application state. Of course, I can add the object as a whole. The class that object belongs to have some properties and all of them will be added with the object to the application state.
But, is there a way to mark some properties of the class to not be included in adding object to the application state? I've thought about writing attribute, but am not sure if it will work.
Thank you for any suggestion.

Hi All,
i would like to do (ASP.NET-AJAX with C# )an autocomplete search textbox(like Google search) that give the user to choose more than one value to research in DataGrid as follows :
1 | 2 | 3
Rome,Paris,New York
when the user insert the first value can have also the possibilities to insert the second value value and so on ... then the datagrid can show all result requested and preferably i should do it in C# .
DO you have any idea how i can do it??
Thanks so much for your attention
Cheers 
|
|
|
|

You can use this control(Multiselect Dropdown for Web Applications[^]) coupled with AJAX calls to make it as an autocomplete list. Based on the text entered, filter the datasource of the checkboxlist and once the values are selected, use the selected values as a folter for your grid.
Try!

Thanks Sandeep,
it is a good example but i can not filter the checklist box meantime i am inserting the value in the textbox...anyway i am trying to repair this error if you have any suggestion i will be so gratefel.
Thanks a lot.
Cheers
