how to get the total row counts in a Gridview control with default paging enabled? My gridview control is bind to an ObjectDataSource control.
The problem I am having right now is that when I loop through the gridview control, it only contains the total row for the current page being displayed on the screen and not
the total row in the entire grid. I am using the the for each loop.
I have a nested gridview like the code quoted below. How to retrieve the counter of each child gridview elements and display it as a field of the parent gridview ?
I am trying to add dynamically gridview (headerstylewidth, back-color, height, etc…, itemstyle width, back-color, height, etc…), in codebehind but I am receiving this error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have done some research research on my problem never found a good tutorial or post to follow. I have an mobile control ObjectList filled with a generic collection of object. This displays the data in tabular form with no problem and I have a column named amount which has a content of type decimal. Now, I wanted to calculate/display the sum of the amount column at the bottom part using the footer template.
As an example, here is my mobile form page (using ObjectList):
[Code]....
and here is my code behind:
[Code]....
What I want to do is to fill-in the mobile label control (lblTotalAmount) with the value of the TotalAmount variable on my code behind but it think the label control is always null.
One of the reports I am creating has dynamic number of columns - a datatable gets returned from the stored procedure, the number of columns depend on the number of items defined in the database (one column for each item, other than some fixed columns). Is it possible for me to use RDLC report to generate a report in this case? All the calculations are already done int he report, I am looking at RDLC only for the sake of export to excel/pdf and repeating header/footer.
how can i find the total null values in a table without using sql cursor .
i want to find the percentage of the data which is avaibale in the table and how much percentage of data is unavailable ( or null). to make a comparision chart.

I have data grid with page size 15. I need to find total number of record(s) in a grid. How to do it?There is two ways to do:
1) Here I have used LINQ. So calling stored procedure again and we can done using .Count () property. But here I don't want make call to data base again.2) Creating our own logic like here I have done like:
I am having problem with calculated columns in the following code

orderDT is the DataTable. When "Extra" column has nothing (I am NOT using Default), "Total" comes out to be blank? "Price" will have a value (always) "Extra" may not have any value
I'm looking at implementing tags in my ASP.NET website. After looking at several algorithms, I'm leaning towards having a couple of database columns that contain one or more tag words. I will then use full-text search to locate rows with specified tags.
All of this seems pretty straight forward except for one thing: I need to be able to generate a list of available tags, which the user can select from.
I know I can write a C# program to build the list of available tags, and then run it once every week or so, but I was just wondering if there's any SQL-method for doing stuff like this more efficiently.
Also, I can't help but notice that the words will be extracted anyway as part of building the full-text index. I don't suppose there's any way to access that information?
I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns() { // The first column to begin to insert the columns in the GridView int columnIndex = 5; BoundField aoColumn = new BoundField(); aoColumn.HeaderText = "New Column 1"; gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback gvMyGrid.Columns.Add(aoColumn); // works fine columnIndex++; foreach (MyEntity my in _myEntityCollection) { BoundField myColumn = new BoundField(); myColumn.HeaderText = String.Format("{0:d}", my.StartDate); gvMyGrid.Columns.Insert(columnIndex, myColumn); columnIndex++; } }
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
I have created a table in my SQL database that has a primary column (Title) and another column named Callsign. How can I access the table row that has a certain title and Callsign using C# in a web page event handler?
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.
So instead of this:
Column1 Column2 Column3 Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data
I'd like something like this:
Column1 Column2 Column3 Data Data Data Data Data Data Data Data Data
Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data
As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.
I'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
