If I have a GridView with 4 columnsthree of them displaying different prices of the same product and the fourth one should display the cheapest..how can I compare the values of the columns ??
View 5 Repliesis there an easy way to compare two columns in two datatable to see if they match? I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2). I tried:
foreach (DataRow dr in dt1.rows)
if (dt2.rows.find(dr["x"]) but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2. Tables have different columns but the same primary column and that's what I need to check
I have a detailsview data control connected to a datasource. i converted all the bound fields to item templates and they have all been converted to textboxes. i need to compare values entered in one textbox and output the value in the other.

I want to get the values from a cell in a gridview so can I do that without selecting a row. Its something like this I have a drop downmenu and based on the value selected in the dropdown menu I have to change the presentation of gridview without going to the database.
View 3 RepliesI have a gridview which has TWO rows (assume this will always be the case). The grid is set in a way that whenever "Edit" is clicked, whole gridview turns into edit mode. (I mean all the rows)
Name
Age
earth
1
mars
1
<<Edit>>
<<Update>>
I want to compare "Age" field, how can I do that. User must put same Age in both the rows
I've created a gridview having an Id column whose visible property is set to false, because I don't want users to see that column. Now when user clicks on the edit button in a particular row I want to fetch the id of the cell in the Id column of that particular row. So, for that purpose I used -
void GridView_RowEditing(object sender, GridViewEditEventArgs e)
{
string Id = GridView.Rows[e.NewEditIndex].Cells[0].Text;
}
In the above code, Cells 0th index is the column index whose visible property is kept false. Now the problem I face here is that if the columns visible property is true then I can easily fetch the contents of that particular cell with the above code. But, in invisible mode I get only "" value i.e. I don't get the text or the content of that cell. Why does it happen? I don't face this problem with DataGrid Control used with 1.0 and 1.1 version. And how to resolve it or in this case is there another way of fetching the content of the invisible cell?
I'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this
Job Location Activity 1 Activity 2 Activity 3

I want to include a footer total that looks like
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0

Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.
I have a gridview to which I am binding a database values. My requirement is to bind the values to the gridview by sorting 3 columns as a default sorting with ASC order in one column and descending order in other two.. Can I do it in my .Net code or should I do that in Stored Procedure? If it can be done in .net code Can you tel me how it can be done.

I need to compare 2 DataTables that do not necessarily have the same structure. One dataTable is the master (dtDB), the second dataTable (dtFORM) is what will have the changes, if any, but not necessarily all of the columns of dtDB. In both tables the first column will be the primary key and all columns that dtFORM has, dtDB will have.
There is another DataTable (dtResults) that will flag the differences

I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?
