I want to do something like this, haven't been able to make it work, I can't get the code syntax right on the style attribute of the div tag:
[Code]....
Maybe it wont ever work and I must find another way?
I have repeater and I am using foreach to go through each row, checking for specific value and assigned the label accordingly. However, when there is a value that is not expected, I would like to highlight the whole row on yellow color.
How can I set only for specific row in repeater with different background color?
1.how to implement whole row as selected in repeater..
2.Like gridview(when select button is clicked then color will b changed to row)..
I am brand new (like 2 weeks) to ASP.NET and VB.
I have a series of linkbuttons that are generated dynamically inside a repeater.
I need the background color of the selected linkButton to change and remain a new color when clicked. I thought that the ItemCommand property of the repeater would do the trick, but it doesn't.
Here is the code for the repeater:
[Code]....
I've a asp.net linkbutton inside asp.net repeater control which renders multiple link buttons. I want to set the style of each and every linkbutton dynamically.
I'm trying
style="color:#6D7B8D;font-size:<%# DataBinder.Eval(Container.DataItem, "Title")%>;"
But i'm getting "The server tag is not well formed" error.
I have usercontrol, I have develop menu there like this
[Code]....
This user control i put several pages. When i goto that perticular page i want change background image of menu item which related to that page.
Can I use variable in eval in repeater? Or how can I use it?
For example:
<%# DataBinder.Eval(Container.DataItem, lngHome) %>
Code behind in form load:
[code]....
I have 2 fields in database table: eng_detail and tr_detail
So how can I use like this <%# DataBinder.Eval(Container.DataItem, lngHome) %>?
I am new to Repeater and DataBinding
In PageLoad, I have
var photos = from p in MyDataContext.Photos
select new {
p,
Url = p.GetImageUrl()
};
repeater1.DataSource = photos;
repeater1.DataBind();
In the Repeater control, I have
<ItemTemplate>
<% Photo p = (Photo) Eval("p"); %> <!-- Apparently I can't do this -->
...
<asp:TextBox runat="server" ID="txtTime" Text='<%= p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss") %>' />
...
</ItemTemplate>
But that is wrong.
What I need is to get the Photo object in ItemTemplate so I can do things with it (eg. to display the time as in the second line in ItemTemplate above). Is it even possible to do this in a Repeater?
i have managed to develop a status wall some what similar to facebook, using Repeater Controls- Parent Repeater is bound to the status and the child repeater is bound to the comments inside that status. I am strugling to implement the following solution- hiding and displaying a btnDeleteComments - depending of the owner of the comment- i.e. only owner of the wall and those who leave the comment can only delete that comment.
Status X
Comment A - left by member John
Comment B - Left by Member Doe
Comment C - Left by Member Harry
The owner of the wall can delete all comments, and only John can delete comment A, Doe can delete comment B and so on Here is what i have tried so far
1. fill a data set with two tables and relate them (table one = status, Table 2 = comments of that status)
2. data bind the repeater to this data set
3. here is the HTML of the child repeater
<asp:Repeater ID="rptComment" runat="server"
datasource='<%#((DataRowView)Container.DataItem).Row.GetChildRows("myrelation")%>'
OnItemCommand="rptCommentonCommand">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<asp:Table
ID="Tblcomments"
runat="server"
Width="70%"
BackColor="#f5f5f5">
<asp:TableRow>
<asp:TableCell>
<asp:Image ID="ImgComPic"
ImageUrl='<%# DataBinder.Eval(Container.DataItem, "["comPicThumbPath"]")%>'
runat="server" />
</asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="TxtDisplayComment"
ReadOnly="true" TextMode="MultiLine"
BackColor="#f5f5f5"
Wrap="true"
BorderStyle="None"
Rows ="3"
BorderWidth="0px" runat="server"
Text='<%# DataBinder.Eval(Container.DataItem, "["Comment"]")%>'
CssClass="WrappedTextBox"
Font-Bold="true"
Font-Size="smaller"
ForeColor="Gray"
Font-Names="Verdana"
MaxLength="250">
</asp:TextBox>
<asp:Label
ID="LblCommentDate"
runat="server"
Font-Names="Verdana"
Font-Size="X-Small"
ForeColor="LightGray"
Text='<%# DataBinder.Eval(Container.DataItem, "["CreateDate"]")%>'>
</asp:Label>
</asp:TableCell>
<asp:TableCell HorizontalAlign="Right">
<asp:Button ID="BtnDeleteCom" runat="server"
CommandName=' <%# DataBinder.Eval(Container.DataItem, "["CommentID"]")%>'
Text="Delete" Width="60px" CommandArgument="DeleteCom" CssClass="buttonDelCom"
Visible=' <%# DataBinder.Eval(Container.DataItem, "["ViewersComment"]")%>' />
</asp:TableCell>
</asp:TableRow>
</asp:Table>
<br />
</ItemTemplate>
</asp:Repeater>
The higlighted bit is causing the cast invalid error- i thought this would do the trick, by deafult all the delete buttons next to each comment is hidden for members other then the owner of the wall- and only if they are the one who left the comment will teh delete button be visible-
<%# DataBinder.Eval(Container.DataItem, "["ViewersComment"]")%>'
The SQL which retreives the comments for a specific status, also retrieves a column2 ViewersComment which is either 'true' of 'false', indicating wether that comment was left by this person viewing the status wall-
I have a GridView with an TemplateField:
<asp:GridView runat="server" ID="gvReport" ondatabinding="gvReport_DataBinding">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("answers") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions") %>' />
</ItemTemplate>
</asp:TemplateField >
</Columns>
</asp:GridView>
What I'd like to do on gvReport_DataBinding is change the field the Evals point to, so I end up with something like:
<asp:Label runat="server" Text='<%#Eval("answers_foo") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions_foo") %>' />
I have gotten this far:
TemplateField tf = ((TemplateField)gvReport.Columns[0]);
But I'm not sure what I should be doing with tf. tf.SomeProperty.Replace("answers", "answers_foo")?
Or am I barking up the wrong airplane on this one?
i would like to know if its posible to change an eval binding of a label on a mouse click. something like:

I am using repeater control in my project and I have made its rows clickable by javascript, when I click a row it changes its background color.
My problem is that when ever i click any server side control in the page the color of the selected row disappear. Can Anyone has Idea to retain the background color.
The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.

I'm trying to make a page, with a textbox, and a linkbutton. In the textbox you can enter any hex colour code you want, then you can click the linkbutton and the pages background will change to that colour. But I don't want the page to postback. I was trying this with themes, and then dynamically editing the CSS file. But neither has worked.
