Forms Data Controls :: Show Hyperlink On Condition In Repeater ItemTemplate

Nov 2, 2010

I have a Repeater displaying some data that doesn't do what I'd like to see. If a certain condition is met (ex: parent.NumOfChildren > 0) I would like a hyperlink shown. Here is what I have so far:

<asp:Repeater ID="parents" runat="server" >
<ItemTemplate>
<asp:HyperLink NavigateUrl='<%# "Children.aspx?parent=" &#43; DataBinder.Eval(Container.DataItem,"Parent_ID")%>'
Text='View Children' runat="server" target="_self" ID="Hyperlink2" NAME="Hyperlink2"/> -
</ItemTemplate>
</asp:Repeater>

In this case, the "View Children" link shows up for every item in my Repeater, but I'd like it shown only if parent.GetNumOfChildren() > 0. Would it be correct to try setting the Visible="true/false" property of the HyperLink? Is that the norm for this sort of problem? Or, is there a way to wrap the entire <asp:Hyperlink> ... </asp:Hyperlink> tag in an if statement that has a reference to the object that is currently being interated in the Repeater? Ie:

if(CurrentDataItemInIteration.GetNumOfChildren() > 0)
{
<asp:Hyperlink> ..... </asp:Hyperlink>
}

To me, the Visible="true/false" solution seems cleaner, if possible.

Forms Data Controls :: Conditionally Create A Hyperlink Within A Repeater ItemTemplate?

Dec 12, 2010

using a repeater to display multiple 'comments' related to a parent database entity (a 'task' in my case). When the user creates these comments they can optionally attach a file. Now, I'm working on the page that lists these comments and I'm not sure how to go about displaying the link to the attached file, if one is present. There may not be a file. The database record that contains the comment will also contain the url to the file if one was attached.

what are my options for this? I would like to just display a link to the file after the comment content, only if a file is available.

Forms Data Controls :: Hyperlink Inside An ItemTemplate?

Jul 15, 2010

I have a DataGridView with a ItemTeplate column, which has a HTML hyperlink (<a href....>) inside. When a user clicks on a link, a popup with a TextBox is showed to the user. Then the user can type a data. With this data, I must update the hyperlink's text in which the user clicked. All using javascript. The problem is that I don't know how to find the Hyperlink because there will be so many hyperlinks as rows in the DataGridView and they will have the same Id.

How can i find the hyperlink using javascript?

Forms Data Controls :: Repeater With A Tag In The ItemTemplate

Jun 22, 2010

I have tried many different combinations to try to get this to work, but I cannot. In the ItemTemplate of a Repeater control, I have a <form> tag. For this third party button to work, each button needs to be surrounded by <form></form> tags. I cannot get the first iteration of the repeater to display the tag, but 2, 3 and beyond, it will. It doesn't make sense to me. Because of this, IE is displaying the page in a funky way.

Forms Data Controls :: Repeater ItemTemplate To Create A Div Container

Apr 16, 2010

In my application I have successfully pulled some rows from a database into a DataSet and then used an ASP.NET Repeater Control to create a div container for each row with each field contained within a span element as follows:

<asp:Repeater
id="repeater"
runat="server">
<ItemTemplate>
<div
id="ticketContainer">
<a
href="#"><img
src="~/Images/treeview_expand.png"
alt=""
runat="server"
/></a>
<span><%#DataBinder.Eval(Container.DataItem,
"USERNAME")%></span>
<span><%#DataBinder.Eval(Container.DataItem,
"COMPUTERNAME")%></span>
<span><%#DataBinder.Eval(Container.DataItem,
"CATEGORY")%></span>
<span><%#DataBinder.Eval(Container.DataItem,
"DATE")%></span>
<span><%#DataBinder.Eval(Container.DataItem,
"TIME")%></span>
<span><%#DataBinder.Eval(Container.DataItem,
"STATUS")%></span>
<p><%#DataBinder.Eval(Container.DataItem,
"DESCRIPTION")%></p>
</div>
</ItemTemplate>
</asp:Repeater>

My problem is that I want the .png graphic link to have a onclick event so that a new div is dynamically inserted under the div to show data from a seperate database table. However since its all declared within the ItemTemplate then targeting the correct div using the JS DOM would be difficult/impossible as the id for each of the divs will be the same.

If this is going to be infeasible then what is the possibility of having data brought in from multiple tables would I have to manipulate the DataSet to include the extra columns as I think Repeater Controls can only have a single DataSet (corret me if i'm wrong).

Forms Data Controls :: Work With Repeater Itemtemplate Coding?

Feb 7, 2010

I have the following code in an aspx form for an asp:Repeater

<ItemTemplate>
<tr class='<%#Container.ItemIndex % 2 == 0 ? "normalRow" : "alternateRow" %>' >
<tr>
<td>
<asp:LinkButton ID="LinkButton1" runat="server">blabla
<%#DataBinder.Eval(Container.DataItem, "ListName")%>
</asp:LinkButton>
</td>
</tr>
</ItemTemplate>

Which produces a syntax error (and a sqiggle blue underline) on

<%#Databinder.Eval(Container.DataItem, "ListName")%>

the build tells me I have an invalid character in the position before the opening <%
above

This only happens after I add the conditional class for the <tr> tag

"<tr class='<%#Container.ItemIndex..."

before I add the above line (to replace the <AlternatingItemTemplate>) everythings ok.

Forms Data Controls :: How To Alter A Control In A Repeater's ItemTemplate From A Handler

Mar 27, 2010

I have a repeater bound to a datasource that servers as a list of birds. When the user clicks an item in the list the bird's image is displayed on the page. I want to change the background color of the item that is currently selected in the OnClick handler for the main item in my repeater's ItemTemplate.

I have changed the styling of controls prgrammatically before and it worked fine but in those cases i used the ID of the control to directly access it in my code behind file. But since this is some arbitrary item in a repeater I don't know it's ID at runtime, all I have is the sender object passed to the control's OnClick handler. So in my code behind file, I tried casting the sender object passed to the OnClick handler to the appropriate type and used Style.Add("background-color", highlitColor) but it failed to change anything.

I had a thought - maybe this sender object gets passed by value so all I did was change the Style of a COPY of the control item.

If this is indeed my problem, how do I start with a casted sender object in an event handler and get a reference to the actual control in order to change it's Style?

Forms Data Controls :: Show / Hide A Div In A Nested Repeater By Clicking On A Button Inside Parent Repeater?

Nov 12, 2010

what changed do I need to make to my code for it to achieve what I'm after.

At the moment I am getting a "cannot cast to type" error message with the below code.

I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

Forms Data Controls :: ItemTemplate (Detailsview) For Certain Fields Does Not Show Up?

In this case I'm having, the ItemTemplate for various fields in my DetailsView (2 in my case) does not show up, but when you click the edit button, the EditItemTemplate shows up. I played with it, moving it around. No matter where I put it, one of the fields did not show up.

To get even stranger (and don't ask me how I came up with this), if I put a dummy boundfield BEFORE it, the ItemTemplate shows up. But this is totally absurd.

Forms Data Controls :: Pass Variable With Repeater Hyperlink URL

Jan 15, 2010

I query the database to get the VideoName and VideoURL of the videos held in my database (Videos saved on the file system with their location stored in the database) then bind the query results to a repeater with the following code

protected void Page_Load(object sender, EventArgs e)
{
// Variables declaration
string strConnString = ConfigurationManager.ConnectionStrings["vidConnectionString"].ConnectionString;
SqlConnection sqlConn = new SqlConnection(strConnString);
SqlCommand sqlcmd = new SqlCommand("SELECT [VideoName], [VideoURL] FROM [Video]");
SqlDataReader sqlReader;
sqlConn.Open();
sqlcmd.Connection = sqlConn;
sqlReader = sqlcmd.ExecuteReader();
VideoRepeater.DataSource = sqlReader;
VideoRepeater.DataBind();
sqlConn.Close();
}

and put a hyperlink into the repeater to list all the VideoName's this works fine but I want to pass the VideoURL to the next page I am using NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" but when I try and load the Page I get the error saying The server tag is not well formed. the whole repeater code is

<asp:Repeater ID="VideoRepeater" runat="server" >
<ItemTemplate>
<asp:HyperLink ID="VideoLink" NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" runat="server"><%# Eval("VideoName") %></asp:HyperLink>
</br>
</ItemTemplate>
</asp:Repeater>

I'm sure i've just got the hyperlink navigateURL wrong put not sure how else to pass the VideoURL variable

Forms Data Controls :: Use Hyperlink With Repeater - Links Are Not Evaluated Well

Forms Data Controls :: Setting Text Programmatically In ItemTemplate Of Gridview Does Not Show

Mar 7, 2010

The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.

On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.

I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.
