ADO.NET :: Iterating Through Rows In A Table Without Using GridView
Feb 25, 2011
how to iterate through the rows in a database table without using a GridView? I have a DataSet and a SQLDataReader, but I can't iterate through rows using the SqlDataReader.
I have a DataTable available with me which contains thousands of rows. There is a column called EmpID which is containing '0' for some of the rows. I want to remove them from my current DataTable and want to create a new correct DataTable. I cannot go row by row checking it since it contains huge amount of data.
i am having Nested Gridview and from the child Grid i have to select the checkbox to retrieve the id's by iterating the child grid and that to on the Button Clik which is outside the Gridview.
in my gridview iam at page load event iam displaying data from view.my 1st column in the gridview is checkbox, when user selects the checkbox and iam using paging in gridview, when user selects the checkbox and selects the rows from first page or from any page, that have to be stored in database.
in my database the table contains
orderid int primary key autoincrement productname nvarchar price nvarchar quantity nvarchar total nvarchar
when user selects the rows then in database how to store multiple rows in that table field

I have made a call logging application in which i have authorised a normal user to edit update and delete from the gridview.But i want to give the admin person rights to see all the complaints deleted updated edited..i have thought a lot but all in vain havent found.
I'm doing this in my Master Page. I want to access a Linkbutton within the Gridview and set the enabled = false; I tested this and it works all the way up to the first if statement.If I insert a response.write to get the frmctrl.ID, I get all of the controls on the page. BUT, can't get the controls within the gridview.How do I get the contorls within the gridview? I prefer not to do this using Findcontorls and esp setting the control to Public.
i have a table that has some columns and rows i want this table to have borders that are visible inside it i want every column an row to be closed in borders how can i do that?
I have an asp:Table and around the mid point of the table there is a DDL with values 2-5. What I want to do is add the selected amount of rows using AJAX right after the table row that has the DDL in it. I know how to dynamicly crate the rows, the info in the rows, and how to use AJAX to make things. Problem is I can not put the ContentTemplate tag inbetween the asp:TableRow which would mark the location I want the dynamic rows to start being added. I did some searching on here but most posts I find start with making the table from code and not the asp:Table tag
I have one table named 'dbo.ac_Products' Within this table there is a column named 'ProductId' There is also another table named 'dbo.ac_CatalogNodes' Within this table there is a column named 'CatalogNodeId' and a column named 'CatalogNodeType'
I need to delete all the rows from 'dbo.ac_Products' and 'dbo.ac_CatalogNodes' where 'ProductId' = 'CatalogNodeId' and 'CatalogNodeType' = 1
I am trying to generate a dynamic table andd add rows to a ASP.Net table control on my UI. My problem is as I add a new row from MyTable, in to another table the table I am copying from, will loose one row. Here is the code:
Table myTable = new Table ();
[Code]....
am just reading one row in every loop and add that row in to another table object, why is 'myTable' loosing loosing one row in each loop?

I have two possible header rows for a DataTable that I build dynamically. Setting the value of a cell works fine. Adding the cell to a TableRow works fine. The problem comes in where I have to build a second possible header row that uses the same cell.
An example is below.
trHead1 = New TableRow trHead2 = New TableRow tcCalc = New TableCell tcCalc.Text = "Rates" trHead1.Cells.Add(tcCalc) trHead2.Cells.Add(tcCalc)
As soon as I make the second row add the cell, the cell disappears from the first row. This really doesn't make sense to me but that seems to be the way it is. If there is a work around other than duplicating the lines;
I 'm curious to know how I could hide rows in my <table> in logical cases where, for instance, I have a list of radio buttons and depending on whether the user selects "Yes", the row below it appears for them to fill in some information.
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)
i have gridview and having few rows. each rows have checkbox,textbox,combo in each column. how can i loop through gridview using jquery and access each elements in rows in loop for collection the value at client side by jquery.
I seem to be running into an issue where my Grid-view doesn't display any rows when the number of items is less the page size (in this case 10), I'm using the object data source and at times it can return 1 or 7 for the number of items function call, which cause the grid view to not display anything at all. If I change the page size to 1 or 7 then the results will show.
I have a gridview which right now is getting loaded with four pages of data. There are 50 rows per page. My problem is I need the "select all" button on my page to select 180 rows, not just the 50 on the page. This is my javascript:
Code: function sel() { var frm = document.forms[0]; isSelected = !isSelected; for (var i = 0; i < frm.elements.length; i++) { var e = frm.elements[i]; if (e.type == 'checkbox' && e.name.indexOf("ckSelected") > -1) e.checked = isSelected; } }
I am more a C# person than javascript, but I am deducing that I need something other than document.forms[0] to represent the entire gridview. Or perhaps, I can't do this in javascript at all. Do I need server code to run and set a session variable, then when the user clicks the button to do something with all his selected rows (it goes to a detail page), query that session variable to see if it's all rows instead of iterating through each gridview row individually to see if the checkbox is checked?
