But ofcourse, it will be the same label each time (not necessarily the label that needs to be updated). I need to update the label that is on the same row as the button.
public string Module(int id,string university) { con = new SqlConnection(ConStr); con.Open(); cmd = new SqlCommand("SELECT college FROM tbluniversity where id=" + id, con); da = new SqlDataAdapter(cmd); con.Close(); ds = new DataSet(); da.Fill(ds);
//Here I want to find the inner repeator of current row then bind this dataset to that.
I tried this technique as suggested on another forum and a couple of other things, suggested on SitePoint as well as others but to no avail. Im trying to find the Label in the repeater to display information depending on the output. However I was presented with the following error:
"Index was out of range. Must be non-negative and less than the size of the collection.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"
It highlights the problematic script as:
Label lblStatus = rptGeneralEnq.Items[0].FindControl("lblStatus") as Label;
I'm trying to access the Label, in the repeater, so that depending on if the text origionally displays true or false (as the label grabs the 'bit' datatype for that record to display) to then change the text to something more appropriate (completed/outstanding) - if at all possible.
I will get this in a Raw format and i am writing this using Response.write("Some.xml"); I need to find out MerchantOrderNumber from this raw data how to obtain this
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[0].Controls[0].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?
how can i set the max-width of the label field, and use multiple line if the text length larger than max-width in the templateitem of repeater. i set the width to 10, but can't fix the length.
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 method that needs to find the repeater control to add data. I try the code below, but keep getting an error "not set to an instance of an object."
am using C# ASP. NET 2.0. I have a string that has 4 parts that are separated by a '_' and here is what I want to do:Find the 3rd part of the string and change '-' to '/' in that string.Example: The string may be as shown: 100_John Doe_01-22-2010_08-00-00.txtI want to be able to pull out the date - in this example it is 01-22-2010, and then change the '-' in that string to '/' and display the
aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.
I need to assign string to repeater label on button click but it is showing error object reference not set
//Label date = (Label)Repeater.FindControl("ltpl_datefor"); Label date = Repeater.Items[0].FindControl("ltpl_datefor") as Label; date.Text = dateforloop.ToString().Substring(0);
On my website i have got a product for sale page, which has a ryt side bar with filter options while the left side bar shows the filteration results. On my ryt sidebar i have used accordion with the repeater control which display the searching criteria from database.For instance I have 2 searching criteria model and price , under model accordion there are three models, what I want to acheive is when a user clicks on that specific model , the page should run a query with respect to that click and show bind the results on the repeater of the left side bar, I know the query to get the results but I dunno how to get the value of that hyper link button, coz these buttons will be dynamic it can be 3,4 or 10. how will i get the clicked hyperlink valueso that I can run the query depending on the model selected.
I am very confused about this problem, and i have tried a lot of things to fix it, but for some reason it rejects finding my LinkButton..aspx page:

I have tried the following things and still getting the message the the object reference not set to an instance:
[Code]....
[Code]....

And still it tells me that the object reference is not set to an instance. I find this very strange and hopefully there's someone who can tell me where i make a mistake?
I want to set Label1 programmatically.How do I get Label1 from the code behind. I guess it is with FindControl but i can't work out the correct syntax.
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
