I have a data table, in one of the column, I will have this data, I will bind the data table to a grid view. I was hoping that this column change to a hyperlink. But, it was display the entire text.
<A HREF="page_url">Remark(s)</A>
When I view the page source code, I saw this:
<A HREF="page_url;Remark(s)</A>
How to correct this?
on which all conditions we use dataset and datatable to bind data to a gridview?
View 2 RepliesI have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
I need a bit of help with a scenario. I am working on a web application that requires huge amounts of data to be Added, Deleted, and Updated. The data entry forms are divided into logical groups through Multiviews. All the information is saved when the mighty Finish button is pressed. The current setup (previous developer) does not allow me to use transactions. Therefore, if I am to save a new Courier to the database, I need to add his/her Distance and Rate info. In addition, I need to add his/her Banned Areas info (Area Name, Post Code).This is where it gets interesting. Obviously, the DistamceAndRate table and the BannedArea table in my SQL Server will have the CourierID as a foreign key. Since I'm going to save the Courier as well as the Rates and Areas info in one go, I cannot have the newly created CourierID before. Therefore, I cannot bind my Grids for Distance + Rates and Banned Areas directly to database.What I am doing is creating two DataTables and managing them in Viewstate through properties as follow:
[Code]....
So, on page load, the DataTables are initialized with a blank schema. Here are the attempted CRUD implementations (Distance and Rate only):
[Code]....
I am having issues when I am canceling a new entry and when I am editing a new entry. In addition, for Distance and Rates, Rate is acting as unique (cannot be repeated) and attempting to control that is also giving me a headache. I end up creating blank rows.And here's the ASPX cut-out:
[Code]....
Hope to get an answer soon.Also, off-topic, I'm using LINQ here. In order to save a Courier and his/her extra details, I first save his/her address to DB. Then I take the ID of the address and save the courier. now the courier ID is avaliable and i start filling extra tables related with the courier table. If something goes wrong, I have to manually delete created rows. LINQ uses transaction internally but only until a SubmitChanges() call. I'm forced to save each entity so I keep calling SubmitChanges().I tried manual transaction but after saving the address inside a transaction, the Address.OID (Address table's mapped prime-key) had a 0. attempting to use this newly added address while saving Courier in the same transaction threw an exception. If there is a way to get the primary key for entities created in a transaction that is yet to be commited, please mention that'll as well.
My DataTable is programatically generated, and contains objects of type JobInstance in the cells.
[Code]....
When I bind this DataTable to an ASP GridView, it only displays the first column. But if I remove the "typeof(Job)" when creating the column (the line with // !!!), the GridView displays all the columns by showing the result of JobInstance.ToString() in the cells. However, I have no access to the underlying JobInstance object, only the string values that are being displayed.
I need access to the JobInstance object when displaying the GridView (for example in the OnRowDataBound), because I want to access the fields inside JobInstance for each cell to determine formatting options, and add other links in each cell.
I have a delimted file , like a csv file but the delimters are # and not ,
I assume I would use SqlConnection and SqlDataAdapter
So for a csv file what is the sequence to read in for example c:datademo.csv
What would the connection string be.
Also can you specifiy a different delimiter.
The code below is what I assume it would possibly look likea although its only a frst guess.

I have a dataset that has two datatables. In the first datatable I have EmpNo,EmpName and EmpAddress. In the second datatable I have Empno,EmpJoindate, EmpSalary. I want a result where I should show EmpName as the label and his/her details in the gridview. I populate a datalist with the first table, and have EmpNo as the datakeys.

My Design is

</asp:DataList>
I do not get results in the gridview, instead have errors. I tried then placing the bound field

<asp:BoundField DataField="EmpNo" />

It throwed an error stating / A field or property with the name 'EmpNo' was not found on the selected data source.

I need to pass the data from GridView1 to a DataTable, and then pass the DataTable to GridView2 and preview it. I have BoundFields and ImageFields in the GridViews. I think I am doing something wrong but I can't figure out how to do it. I know I have to iterate through the GridView.Rows, but I don't know how to pass it to the DataTable.
