Fetching The Id From The First Column Of GridView?
Jan 12, 2011
I have a Grid in which I am showing some records in each row. Here's how it is:
Now, my problem is that when I press the view button, I want to fetch the ID from the first column in a session variable so that I can display the same ID on the next page.
For the ItemTemplate of EditButton, I am using this code:
name | phno. | emp_name(in dropdown) | buttonfield
wen user comes on this page this grid comes filled but then I need to select 1 emp_name from dropdown and click button(in last column) corresponding to that row. then on clicking that row button it should fetch that toq Primary Key and dropdown corresponding id. how? Wen I m fetching its fetching row index as 0 though it is no.4 record as per database(coz my records are in desc.order). I mean its giving row index as per grid and not as per my actual table(primary key).
I want to find a control in gridview using client id of the control as the id is changing dynamically. I am getting the client id but it is not getting assigned in a variable whether of string type or object type.
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
I have a gridview which is present inside a repeater. I have been successful in displaying the data inside the grid view. Now I want to fetch data from the gridview. But i have not been able to fetch the data from the grid view.
I have two databases (DB1 & DB2) from which i wish to build a single table/gridview output, ideally i want to be able to sort the table by using any data.
However i cannot seem to figure out how to have more than one datasource per Gridview, and if i have more than one Gridviews then i can't sort all the data by any of the columns.
This is a oneway street, i do not want to update the databases from the webfront end.
As per my requirement, I am getting CompID, Company Name and URL from SQL database. I want to display just CompName and URL in gridvew. So, I need to hide the CompID in gridview. One way I can do BoundField field Visible to false but I need to retrive that compID id when user selected any of the row. if I set visible to false user wont see any compID in gridvew but I want access the selected compID also using SelectedRow.Cells[1].Text..
Now what I want to achieve is, when user clicks IsComplete checkbox, she must enter the date of completion. So, I want a validation (client side) on DateOfCompletion if the checkbox is selected (checked). And, I also want to use Validator Callout Extender if possible.
I am using GridView ,I want to do a validation like if i edit any one of the Cell in that column, it will through the validation when the sum of column value is more than 100. How can i do this validation?
I have a grid view with 4 columns and 12 rows. Getting the row index is not problem; ;however, I cannot find a way to get the column index of the cell that i select.
I have several columns and I want to have borders on the left and on the right of some like this:| column1 column2 | column3 column4 |If I specify the border in the ItemStyle, it shows on both side and won't render the absence of column between columns 1 and 2 and column 3 and 4.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
How can I fetch the first two information from it into my aspx page? for example I want to read the first two timings.. Should I use xmlReader or what?
1)usign execute scalar i will get 1st col and 1st row value.
2)using dataset i will get whole table.. if my stored proc has 2 queries then i will get 2 tables within same dataset.. i can reference therese using ds.tables(0).rows(value).
3)suppose i use a datareader then i will get multiple-rows. i want to know how to get these each separate rows coloumn values into variables. below is the reader aspx.vb
reader = cmd.ExecuteReader(); while (reader.Read()) {
4)what is it mean by data reader is forward only method of getting data.
5)why do we do readeritem.tostring()
6) can you tell me the basic how is this reader,ds,scalar works.i mean i know to use but donot know basics esspecially the dataadpapter.why do we fill it when using dataset.
i m trying to use the sql datareader to fetch a single row at a time i wanna know can we use it to fetch a single row at a time or not if yes i m unable to figure out what i m doing wrong here bcus its not returning any data
[Code]....
of course data is present in my table bcuz when i m using dataset i m able to the return the single row throuugh dataset
