ADO.NET :: Filling Labels With Table Data Outside Datalist Using Single Call To Db?
Oct 15, 2010
On a single page, I'd like to fill 2 hyperlink controls as well as a datalist control with table data using one call to the database. The page looks like this:
[Code]....
In the code-behind, I've tried several ways to accomplish filling the labels and the datalist with a single call but I can't make it happen without using either reader.read() or if (reader.read()) on the line before I make the call to fill the labels and the datalist. This fills the hyperlink controls correctly but advances the recordset forward by one, which results in the datalist missing it's first record.
I've tried using while (reader.read()), but I get an "invalid attempt to read when no data is present" error. I've also tried using if (reader.hasrows) but I get the same error as above.Here's an example of one of the 2 ways I can get the labels and the datalist filled with data, but again this advances the recordset forward and I end up missing the row of data:
I have a page with a datalist on it, with an image button and some labels in the datalist item(1,2)..
I have some more labels on the page which get their values from querystrings(17,18)..
I have more labels which are empty (34,35)
On image click in the datalist item, i want the labels from that item to add with the labels outside of the datalist, and the last lot of labels to show this number..
I have 3 gridview,4 lables having the information, i have a button(Report), when i click this i want make this as Non-editable format single report. i have seen converting Webform to PDF but we should fall back to 3rd party tool to produce the report.
I need to create a display grid of picture cells 5 columns by rows determined by database select. Each cell to contain picture, title, name, phone number pulled from database. How do I create a table like structure and populate it? Can a DetailsView control be called into each table cell with the table row count being determined by the same select statement?

I have a table on top of my gridview. My table contains labels. However, though I would like to align the size aka the length of the table with the length of my gridview so that everything looks decents. How do you go about doing so.
I have a datalist that is populated via and SqlDataSource. Code is VB

I have Table named PRODUCTS , that have 4 column productid, productprice,productname & discount( type numeric(18,0)) .. i am using datalist with itemtemplate that have 4 label to display all ..
I am binding datalist on pageload, now i want that Label4 with "discount" should only visible for those product that have discount , otherwise it remains hidden,
Problem in my code is that when i run it , label becomes invisible for all products whether they have discount or not. Here is my code i am using for it:
ds1 is my dataset
foreach (DataListItem item in DataList1.Items) { for (int i = 0; i <= ds1.Rows.Count - 1; i++) { double[] arr = new double[ds1.Rows.Count]; double temp = double.Parse(ds1.Rows[i]["discount"].ToString()); arr[i] = temp; Label lbl = item.FindControl("Label4") as Label; if (arr[i] == 0) lbl.Visible=false; } }
i have an datalist within that i have a imagebutton while clicking this i just call an js function, here when i pass the identity column value from hiddenfield then js function calls good, if i pass the Imaagebutton url then raise an error as "Error on Page".
here is the code
function onGridViewRowSelectedZoom(imagePath) { alert('hai'); alert(imagePath); }

I am trying to export just a table that is contained on my page. I have some filters above it but when exporting, all the text and filters are copied into this file.
This is the code:
tableCreateOrders a = new tableCreateOrders(dtReportColumns, 2, 10); divResult.Controls.Add(a.displayTable()); Response.ContentType = "application/ms-excel"; Response.AddHeader("content-disposition", "attachment; filename=orders.xls"); Response.Write(a.displayTable());
a.displayTable() is the object containing the table, but the filters are defined on the .aspx so there is no way the command take it. Is there anything I am doing wrong?

I am trying to show data on a datalist, but with some caveats.1. WHERE the User Id = the querystring id pass on the url2. WHERE the table 'resume', the 'permissions' column shows as '1'orWHERE the table 'resume' the 'permissions' column contains within it any number from 2-4, any of which matches one or more numbers in the 'permissions' column of the 'contacts' table (but WHERE the 'contacts' table where the url querystring id = column 'myuserid' and the signed in Profile.UserName = the column 'theiruserid'Its complicted, but i dont know how to reference another data table when selecting data from the first table...?
I'm using a datalist that uses an item template to display results from an objectdatasource. The thing is, I'm only fetching a single record so a datalist doesn't seem like the best option. Is there a more suitable control I can use?
Also, how do I access the data on an objectdatasource that has been created in design view from code-behind. I've tried google but with no success.
Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'. In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I just wanted to know if there is any way to dynamically set the width of a column inside a table within a datalist based on the length of the text fetched from the database.I am inserting my code.
