Forms Data Controls :: Count Values Inside A Dataset - Or Gridview
Mar 16, 2011
I create a gridview in the code behind and fill it with a dataset. I want to provide some information about the data in a label above the grid. In the code posted I want to be able to say something like "Story county has 6 overdue tasks, Polk county has 12 overdue tasks, etc ..." So far I have been trying some different combinations with the dataset and the gridview but nothing gives me totals.
When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.
Im developing a web application. I've to create a grid view which displays the brand and model of Mobile handsets. In edit template i've added a dropdown list box for brand and model. The user have to select brand, the model dropdownlist should display its respective model names of the selected brand. How to accomplish it..
I have a gridview that have some boundfield and a table inside a tamplatefield. That table have 6 input (hidden) that binds when the page load.
How can I get the values of those 6 input inside the table from server side?
I know how to get the boundfield values , with
Dim selectedRow As GridViewRow = GridDetail.SelectedRow Dim fName As String = selectedRow.Cells(1).Text Dim lName As String = selectedRow.Cells(2).Text Dim Iname As String = selectedRow.Cells(3).Text
I HAVE A GRID VIEW IN asp.net + VB Code. There is a drop down list and the selected data is displayed in web page. I placed a label in web page and code behind i used following code.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound Label1.Text = GridView1.Rows.Count.ToString() Dim ONYO As Integer = 0 Dim DONE As Integer = 0 For i As Integer = 0 To GridView1.Rows.Count - 1 If GridView1.Rows(i).Cells(0).Text = "ON YO" Then
I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these
I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see: http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
string studentno = "select regno from stu_ref where batch='" + dropbatch.SelectedItem.ToString() + "'"; SqlDataAdapter dastudent = new SqlDataAdapter(studentno, cn1); DataSet dsstudent = new DataSet();[code]....
form the above coding i will get all values form the table stu_ref of regno of student now i need to get the first and the last regno from the table
I have a gridview inside which there are 4-5 checkboxes. In that gridview, I have 10 rows too. So, Now what i want is.
IF I check, 2 checkboxes and don't check remaining checkboxes. how to save the value of the checked checkboxes value as Y and unchecked checkboxes value as N into the database.
I want to get Row Fields in Gridview on Checkbox Change inside gridview.I have checkbox column in grid, i want to get row details in msgbox as i select checkbox. On selected index change of checkbox inside ridview.Everytime i select checkbox, it gives msgbox for row details.
i have a datagrid with paging on my .aspx page now i want the footer of the grid to display the total count of row on page and the grand total also
like
1-10 of 50
11-20 of 50
i got this code from somewhere but not working.
protected void GridView1_DataBound(object sender, EventArgs e) { // Set the text in the first cell of the footer row to equal the number of // Rows in the GridView GridView1.FooterRow.Cells[0].Text = String.Format("Total: {0}", GridView1.Rows.Count.ToString());...............
on my program, i have count button on below listview, when user click that button, system will auto count salary + extra_salary and updated into total_salary...
I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
I habe a arraylist that can pass in the result of a quiz and once the user finishes this quiz, the result will be displayed in a gridbiew which is binded into a sqldatasource. In this gridbiew, there is this column which will highlight the the result of this qn which displays correct and incorrect. what i want to do now is, i want to count the number of correct answers. I want to count all the correct answers and bind it to a label in the same page.
I want to count all checked checkboxes in gridview. How can I possiblty do that? I've tried several ways but didnt work. This is my code for checkboxes.
I'll start off with a snapshot of the application i'm working on.
Basically, what's going on is i'm using a bunch of sqldatasources to track truck loads (shown) based off a date/ date range. As there are generally multiple loads that all have the same information, so the information is grabbed with a SELECT DISTINCT so that you're only seeing one entry per multitude of loads. From there, customers can select the load type they want to work with and it goes into more detail, such as who trucked the different loads in, where it came from, where it's going to, references, that kinda stuff.
My question is, would it be feasible to show how many loads there are in total per distinct select? For instance, the top entry actually has 14 loads that are similar to that entry. How would I go about showing it has that total of 14 loads that could be shown?
