C# - Inline Script Conditional Statement Inside A ListView?
Dec 15, 2010
I'm trying to display an image inside a ListView control based on the value of a databound property. I've tried two methods of doing this (one at a time) and both returned errors of "The server tag is not well formed". Consider the code below.
<ItemTemplate>
<div class="left">
<!-- Method 1 -->
<img src="media-play-button.png" alt="Play" class="mediaplay noborder" runat="server" visible="<%# Eval("MediaType").ToString() == "video" %>" />
<!-- Method 2 -->.........

is there a way that I can format a Date binded in a ListView?I have this snippet of ListView
[code]...
What I want is to Format that date to output something like this Oct. 20, 2010. Normally if it is a DateTime I can write something like this requiredDate.ToString("MMMM dd, yyyy") but inside the ListView binded data I cannot do that.I don't want to use OnItemDatabound. I just want it to be formatted inline.

EXISTING CODE:
<asp:HyperLink ID="HyperLinkG102" runat="server" Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) %>' Text='<%# Eval("L_GalleryName") %>' NavigateUrl='<%# String.Format(".... /findlink.aspx?linknum={0}", Eval("L_ID")) %>' Target="_blank" Font-Size="9"
ForeColor="Blue"></asp:HyperLink>
Is there anyway to put an OR conditional in the Visible text?
( Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) OR Visible='<%# (Convert.ToInt32(Eval("L_Rank")) != 0 ) %>' )

I use LINQ.But I can not add data twice "ZnizanaDnevnica.
How could you do one box:
tbl_dnevnice_obracun tbl_dnevnice_obracun = new tbl_dnevnice_obracun()
{ZnizanaDnevnica = ((totDiffHours> = 6 & & totDiffHours <8)? Convert.ToDecimal (dt.Rows [0] ['Znizana']. ToString ()): 0),((totDiffHours> = 12
& & totDiffHours <24)? Convert.ToDecimal (dt.Rows [0] ['Znizana']. ToString ()

this might be an easy one, but I just can't get it.I am creating a page which will query a table with many columns and most items are not unique. I need to be able to get a list of records that match as many of the (up to 4) search criteria as possible.Example:am user searching for the following items, I enter at least one and up to 4 of the items below in a text box:Name, age, gender, weight (user may or may not fill in all of them).If he just enters "F" for gender, then he will get a list of thousands of females with their name, age, gender and weight.However if he enters "F" for gender and "300" for weight, he will get a much smaller list of returned records.I need to be able to create a sql statement that can perform that search with that functionality.

I have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :

As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me.

I am trying to do an inline IF statement inside a asp:Repeater control to add a class to the first item, but I can't quite seem to figure it out.
Basically the code I have right now that is not working but should give an idea of what I'm "trying" to do looks like this.
<asp:Repeater ID="rptrTabRepeater" runat="server">
<ItemTemplate>
<div class="tab <%= If Container.ItemIndex = 0 Then %>highlight<% End If%>">
'Other stuff here
</div>
</ItemTemplate>
</asp:Repeater>
I have tried using the OnItemDataBound event but the delegate interface cannot return a value. If I'm going to do anything from a code-behind function really it would just need to be an "echo" kind of function which I wasn't quite sure how to get the item index in a code behind function. If I could do something inline like my example that would be the best solution for me.
EDIT: The compile error I am getting is:
Compiler Error Message: BC30201: Expression expected.

I have few inline sql statements with some arrays and if loops. I want to change them all into one stored procedure in SQL server 2005.
As i am learning SQL, i have got no idea about how it should be done with arrays and if loops. Is that possible to send arrays into stored procs or is there any other solution.

I have a conditional Eval statement in a Gridview that returns a boolean result to display an image if two datafields(strings) are identical:
Visible='<%# Eval("customerA").Equals(Eval("customerB")) %>'
Works great except I don't want the image to display if both datafields are empty. How can I add that logic into this Eval stmt?

How can I achieve the desired effect?
Here's the code:
<% if(!String.IsNullOrEmpty(%><%#Eval(Container.DataItem,"OrderXml");%><%)){ %>
etc., which is placed inside of an ItemTemplate inside of a TemplateColumn. In the CodeBehind page I will bind a value to the OrderXml field, which occasionally is NULL.
Unfortunately I get compilation errors.

How can I make this show yes or no instead of true or false?

I'm trying to get a Razor conditional to write a few characters into an HTML page, but I can't figure out the syntax to pass the text characters straight to the screen. This bit of code works correctly:
@{if(sortColumn=="BbConvTerm"){<p>ASDF</p>}}
But I don't want those <p></p> tags. I just want it to insert the "ASDF" characters into HTML. For example:[doesn't work] @{if(sortColumn=="BbConvTerm"){ASDF}} [doesn't work] @{if(sortColumn=="BbConvTerm"){new HtmlString("ASDF")}} [doesn't work] @{if(sortColumn=="BbConvTerm"){Html.Raw("ASDF")}}

I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

I am loading the autocomplete extender properly but I need the PK from the selectedValue. I have looked at other examples and they do NOT show how to drill into the tabcontainer, then drill into the listview, and then locate the extender value. Here is what I have so far. My "TABCONTAINER" value shows the extender correctly but I am unable to locate it.
