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?

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)
Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c)
c.Open() if Not IsNothing(da) Then da.Fill(dt)
[code]...
When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.
I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
I have two datatables, I want to get all records which are in one datatable but all matching records which exist in another datatable should not be available.
In terms of set, you can say that record which are in 1st datatable but not in 2nd DataTable.
I have a datatable with 17 columns and a bunch of data. I wnat a datatable with only 6 of the columns and the data for those 6 columns. So I need a subset of the original datatable. How do I loop through the original datatable with 17 columns and end up with a datatable with only the 6 columns I want with the corresponding data for those 6 columns?
Below is a beginning attempt to increment through a DataTable populated by a Stored Procedure and create a new DataTable where every Category is represented by exactly four products. I need to add dummy product entries for some and skip over those with over four products.
A) - I think I understand the basics but this builing from scratch is not my practice. 1) I do not know how to query a previous row in reference DataTable. 2) I do not know how to jump to next row from IF construct. 3) I hope I am able to build a DataTable row by row. 4) Partial sample data is at bottom of pseudo code
I want a 10*10 (100 cells which is created dynamically) grid to be displayed in the following manner.Initially all the cells' color is green.If i click on any cell its color becomes red if it is green and if i click again it becomes red.(Toggle the cell color)I should be able to display dynamic number of link buttons in each cell.On the click of which it pop ups a window.
I'm relatively new to ASP, so this may be a simple fix that I am just not figuring out (here's hoping!). I am working in VisualStudio2010 using C#.
Basically, I have a table in SQL with the following columns: Product, ProductGroup, Attribute1Value, Attribute2Value, Attribute3Value
For each ProductGroup, the Attribute definition is different. For instance, in ProductGroup1, Attribute1 is Size and Attribute1Value might be 2,3,5, etc. In ProductGroup2, Attribute1 is Quality and the Attribute1Values would be Standard, Economy, Premium, etc.
I will only ever pull in one Product Group at a time and would like to have my column headers reflect the Attribute definition (Header= Size rather than Attribute1Value when applicable".
What I would like to do is pull in a gridview that is invisible with the columns ProductGroup, Attribute1, Attribute2, Attribute3 and then assign the values within the column to be variables that I can use to reassign my column headers. I have been able to set column headers based on other variables (specifically the selected value from a dropdown), but am having trouble with the code to set variables equal to gridview values.
I got the error message that my index was out of range. I thought at first that this may be because my Gridviews have no rows upon page load, only after a few selections from DropDowns, but I don't know if they are at all related. Is there a better way to do this in general?
Although I'm a total novice at building web pages, I figured the best way to learn is to do it. I've used a master page and, so far, all the basic information pages work OK.
My problem starts when I have several options for the same Content Holder. Is it possible to use clickable cells to show various *.html files in a different row in the same table.
I can show an image using a script but not a file.
<script type ="text/javascript" > function Change() { document.getElementById ('tdContentItem').innerHTML ='<img src="Images/Thumbs/Councillors.png"/>' } </script>
What I need to show is a clickable imagemap that loads the resulting pages into the same row.
My code is below. I want to add space between cells in tableCell()something the equivalent ofI am NOT looking for cellpadding or cellspacing because they both add space between the left cell border and the left table border;I want to add space between two CELLS, not the table and the cell;
I am working with gridview in my application. I want to get values of a particular cell in my rowcommand event on the click of a link button in a button field. Following is my code from aspx:
I have an ASP.NET page that uses a repeater to populate a grid. There will eventually be a dozen or so columns, one of which is a linkbutton that does a postback (it removes the row). The rest of the row I want to be clickable and navigate to the specified url I set up at runtime.
how can i access the controls in a gridview cells in which i use for inline edit? In the gridview, there would be two controls in a cell, which is a label and a textbox. When user navigate around the gridview, next cell would turns textbox become visible and label become invisible. How can i enhance the code below. I'm not familiar with javascript,
function NavigateCell() { if (event.keyCode == 37) { //to the left if (currentCellReference.previousSibling.cellIndex != 0) { currentCellReference.style.borderWidth = 1; [code]...
