C# - RowFilter On A DataTable To Display In A Gridview?
Aug 10, 2010
I have the following code which doesn't seem to work. In the Page_Load function I populate the DataSet and display the results in a grid view.
newsCommand = new SqlCommand("SQL code here", dbConnection);
newsDataSet = new DataSet();
newsDataAdapter = new SqlDataAdapter(newsCommand);
newsDataAdapter.SelectCommand = newsCommand;
newsDataAdapter.Fill(newsDataSet, "Bulletins");
[Code]....
Yet the gridview shows the data it orignally loaded, and not the filtered data. The only thing I can think of is that I'm not using the DataTable in the Page_Load function.
I have a gridView which is populated with the code below. This is working perfectly except for one issue. In the "Region" column, I need for each region name to be a hyperlink. If I set the row code to dr(0) = "<a href='table_display.aspx?IO_ID=" & objDataReader("IO_ID") & "'>" & objDataReader("Region") & "</a>" it actually displays the entire string of text from "<a href..." through "</a>", but not as a hyperlink. I have read in many places to manually put a hyperlink field in the aspx page, but I would really prefer to do this programmatically in the code-behind.
how to join two datatable datas into one datatable to show in one gridview
i.e in 1 datatable i have username and pwd and in another datatable i have that user details. how to show all these in one datatable to get those values display in gridview(asp.net)
I have a method that I created to use the row filter on a dataview. It works fine with a single filter but when I add the AND statement to the end it throughs and execption.

Syntax error: Missing operand before 'And' operator.I spent all day Friday trying to debug this but got nowhere?
as a php developer ive been told to go the MVC route which ive been trying since yesterday. Im using visual web delveloper 2010 express and im using the MVC template project.Ive basically got a news table in MSSQL Express, in there are these fields ID,(Title,Body,PostedOn,PostedBy) all i wanna do is loop through them to put them on the view.Im after a nudge in the right direction, I want to be able to do a SQL lookup in the controller put that data in a DataTable then run a foreach loop on the table to display this on the view. The problem im getting is I know youre not suppsed to put any HTML in the controller and I cant pass the datatable to the view to do the loop in the view.. so where/how do I do the loop.
I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.)
Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.
I am filtering dataview using my Date Column but the result is not proper because the Field value also stores time, so I want to convert this Date Field to only Date during Filter. How can I achieve this? Here is my code. And the actual value I am getting in the Dataset Field "CreationDate" is a DateTime field which is like
First off, im using a checkbox to highlight a true or false value from a dataset which I want to be able to change it. Unfortunately databinding the DataTable to the GridView checkboxes doesnt work (as you probably know) as it requires it to be in "edit" mode.
The way I've gotten round this is having the checkbox reading the data table value seperately rather than being databound and locked:
So that solves checkbox values from DataTable -> GridView, now I need to do the opposite having the changed checkbox values go from GridView -> DataTable as it is not ready to submit it to my data source (SQL) just yet.
I figure I need to run a loop through the GridView rows, thats a give'un, what I can't figure out is how to replace/update just a single value in a row of a DataTable , only the ability to add or remove an entire row by the looks of things (something I don't want to do).
So can anyone offer a workaround? Or is there a way to have a databound but always editable checkbox in a gridview?
I would like to display the relevant data about the specific productIDs in the DataTable in a DataList with the Product data being drawn another Database called Products.
How do I do this?
And how do I write the select statement in VB.net in the SqlDataSource of the Gridview?
i have the dataset with one table.Table contains three column like 'Name','Location','Pin'.I would like to move the data from another table based on schema.
If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
im trying to copying specific record from one datatable to another datatable i used below code
public System.Data.DataTable selectspecificdatarow(System.Data.DataTable dtg, int count, int startindex) { System.Data.DataTable dtn = dtg.Clone(); for (int i =startindex; i < count; i++)
[Code]....
its taking too long time in cloneing is there any better way to do this task which is Time effecent
