I have a label control in datalist. When thw word is long, the text of label corrupts the design. Label hasn't a multiline property.I tried different ways . I tried to use textbox like a label but this time I can't give a link to textbox.I tried to use MeasureString() method for the label. But I couldn't do it.
Lets say I have the above situation, and I need to update the appropriate label based upon which button is clicked. I have no idea how to do this. I can find a label via: (Label)Repeater2.Controls.Controls.FindControl("Label1");
But that only gives me the same label each time (so no matter which button I click the same lablel gets updated). How would I find the correct label to update?
I have a repeater set up which takes all records from a SQL DB table and displays. One of the items in this repeater is a Label. The Label's job is to display the 'Responded' field of the database, which is a 'bit' Datatype.
However, when the label displays naturally, it will show TRUE or FALSE. As this is not appropriate for the end-user they would prefer If True = Completed and if False = Outstanding.
I have written the script to do this in an ItemDataBound field, so that (hope my understanding of itemdatabound is correct), everytime a record is found it checks to see what the value is in responded field and 'if true then do X else do Y'.
However, when I have ran it through debug mode it shows that the Label Text of the label is just "". Therefore it will always show 'Outstanding'. In addition, the AssociatedControlID is also blank (""), although I am unsure whether this would present a problem or not.
If any extra information is required I'll do my best to provide it.
I have a label control inside of repeater and I can't seem to get FindControl to locate the label inside of the repeater or even the repeater itself. I'm not sure what I'm doing wrong here. OnItemDataBound is firing because "hello1" is being written but if I put anything inside of the For Next loop of rptMarketFundamentals, nothing is run inside of it.
<asp:Repeater id="rptMarketFundmentals" runat="server" DataSourceID="dsMarketFundamentals" OnItemDataBound="rptMarketFundamentals_ItemDataBound"> <asp:Label ID="lblOwnershipCategory" runat="server" Text='<%# Eval("OwnershipCategory") %>' /> </asp:Repeater> Sub rptMarketFundamentals_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs) Response.Write("hello1") 'this works Dim dataItem As RepeaterItem For Each dataItem In rptMarketFundmentals.Items Response.Write("hello2") 'this does not work Dim lblOwnershipCategory As Label = CType(dataItem.FindControl("lblOwnershipCategory"), Label) If lblOwnershipCategory.Text.ToLower = "family firm" Then blOwnershipCategory.CssClass = "highlight" End If Next End Sub
I have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?
I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.
I want label to display limited text say 20 char even the data it retrieve from database may be more than 20 char.. like in gmail,we see message body limited when we click it display whole message..how is that possible...?
I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
